INTRODUCTION TO CORE PROCESS

核心工艺介绍

INTEGRATED SEWAGE TREATMENTEQUIPMENT CORE TECHNOLOGY/核心技术

MICRO ELECTROLYSIS PROCESS

Micro electrolysis technology is an ideal process for treating high concentration organic wastewater. when it is used to treat high salinity, refractory and high chroma wastewater this process can not only greatly reduce cod and chroma, but also greatly improve the biodegradability of wastewater. This technology uses the micro electrolysis filled in the micro electrolysis equipment without electricity iron carbon filler produces "galvanic cell" effect to treat wastewater. When water is supplied, numerous "galvanic cells" with potential difference up to 1.2V will be formed in the equipment. The primary battery battery uses waste as electrolyte, and electric current is formed through discharge to conduct electrolytic oxidation and reduction treatment of waste water to achieve the purpose of degrading organic pollutants.

The new ecology [OH], [H], [O], Fe2+, Fe3+, etc. generated in the treatment process can have redox reaction with many components in the wastewater. For example, it can destroy the chromogenic group or color aid group of the colored substances in the colored wastewater, or even break the chain, so as to achieve the role of degradation and decolorization; Fe2+generated further oxygen. It is formed into Fe3+, and their hydrates have strong adsorption flocculation activity, especially the formation of ferrous hydroxide and ferric hydroxide colloidal flocs after pH adjustment by adding alkali coagulants, their flocculation capacity is far higher than that of iron hydroxide colloid obtained by hydrolysis of general agents, and can flocculate a large number of small particles and metal particles dispersed in water, And organic macromolecules Its working principle is based on the combined action of electrochemistry, oxidation reduction, physics and flocculation precipitation. The micro electrolysis process has a wide range of applications. The advantages of good treatment effect, low cost, short treatment time, convenient operation and maintenance, low power consumption, etc. can be widely used in the advanced treatment of industrial wastewater.

Micro electrolysis process is widely used in dye, printing and dyeing wastewater, coking wastewater and petrochemical wastewater; Leather wastewater, papermaking wastewater, wood processing wastewater; electric plating wastewater, printing wastewater, mining wastewater and other wastewater containing heavy metals; organic phosphorus agricultural wastewater, organic chlorine agricultural wastewater; Pharmaceutical and chemical industries and other high concentration wastewater industries.

APPLICATION EFFECT

INTEGRATED SEWAGE TREATMENTEQUIPMENT CORETECHNOLOGY/核心技术

微电解工艺

微电解技术是处理高浓度有机废水的一种理想工艺，该工艺用于高盐、难降解、高色度废水的处理不但能大幅度降低cod和色度还可大大提高废水的可生化性。该技术是在不通电的情况下，利用微电解设备中填充的微电解铁碳填料产生“原电池”效应对废水进行处理。当通水后，在设备内会形成无数的电位差达1.2V的“原电池”。“原电池“以废水做电解质，通过放电形成电流对废水进行电解氧化和还原处理，以达到降解有机污染物的目的。

在处理过程中产生的新生态[0H]、[H]、[0]、Fe2+、Fe3+等能与废水中的许多组分发生氧化还原反应，比如能破坏有色废水中的有色物质的发色基团或助色基团，甚至断链，达到降解脱色的作用：生成的Fe2+进一步氧化成Fe3+，它们的水合物具有较强的吸附-絮凝活性，特别是在加碱调pH值后生成氢氧化亚铁和氢氧化铁胶体絮凝剂，它们的絮凝能力远远高于一般药剂水解得到的氢氧化铁胶体，能大量絮凝水体中分散的微小颗粒、金属粒子及有机大分子、其工作原理基于电化学、氧化-还原、物理以及絮凝沉淀的共同作用。微电解工艺具有适用范围广、处理效果好、成本低廉、处理时间短、操作维护方便、电力消耗低等优点，可广泛应用于工业废水的深度处理中。

微电解工艺广泛应用于染料、印染废水、焦化废水、石油化工废水：皮革废水、造纸废水、木材加工废水；电镀废水、印刷废水、采矿废水、其他含有重金属的废水；有机磷农业废水、有机氯农业废水；制药化工等高浓度废水行业。

应用效果

INTEGRATED SEWAGE TREATMENTEQUIPMENT CORE TECHNOLOGY/核心技术

FENTON OXIDATION PROCESS

The mixed solution of hydrogen peroxide (H2O2) and divalent iron ion Fe oxidizes large molecules into small molecules and small molecules into carbon dioxide and water. At the same time, FeSO4 can be oxidized into 3-valent iron ions, which has a certain flocculation effect. 3-valent iron ions become ferric hydroxide, which has a certain netting effect, so as to achieve the purpose of water treatment.

ADVANTAGES OF FENTON REAGENT METHOD

(1) The reaction rate is high. Under the action of Fe2+ions, H2O2 can quickly decompose to produce • OH. • OH has a very strong ability to obtain electrons, that is, the oxidation ability. The oxidation potential is 2.8V, and its oxidation ability is second only to that of fluorine;

(2)•OH can directly react with pollutants in wastewater to degrade it into carbon dioxide, water and harmless substances;

(3) Because of the strong oxidation capacity of hydroxyl radical, the reaction speed is fast, and the treatment requirements can be met in a short reaction time;

(4) Fenton reaction can be used as a separate treatment process or combined with other treatment processes to provide treatment efficiency and reduce treatment costs.

The application of Fenton oxidation method in wastewater treatment has incomparable advantages compared with other methods. However, due to the high price of hydrogen peroxide, if Fenton reagent is used alone, the cost is too high, so it is usually used in combination with other methods in practical application, such as coagulation sedimentation method, biological method, activated carbon method, etc., for wastewater pretreatment or final advanced treatment to obtain good results.

Fenton reagent is added to pretreat wastewater through hydroxyl radical (·OH) reacts with organics to couple or oxidize the refractory organics in wastewater to form intermediates with small molecular weight, thus changing their biodegradability, coagulability, sedimentation and solubility, and then

Removal by coagulation sedimentation or biochemical method can achieve the purpose of purificatior

Some industrial wastewater, after physicochemical and biochemical treatment, still has a small amount of refractory organics in the water that have not been removed. When the water quality fails to meet the discharge standard, Fenton oxidation method can be used for advanced treatment. For example, when neutralizing biochemical method is used to treat dye wastewater, there are still biodegradable organics, COD and chromaticity of effluent cannot meet the discharge standard. The addition of a small amount of Fenton reagent can achieve the goal of removing COD and decolorization at the same time, so that the effluent can meet the national emission standard

INTEGRATED SEWAGE TREATMENTEQUIPMENT CORE TECHNOLOGY/核心技术

芬顿氧化工艺

过氧化氢(H2O2)与二价铁离子Fe的混合溶液把大分子氧化成小分子把小分子氧化成二氧化碳和水，同时FeSO4可以被氧化成3价铁离子，有一定的絮凝的作用，3价铁离子变成氢氧化铁，有一定的网捕作用，从而达到处理水的目的。

Fenton 试剂法的优点

(1)反应速率高，在Fe2+离子的作用下，H2O2能够迅速分解产生·OH，-OH具有极强的得电子能力也就是氧化能力，氧化电位2.8V，其氧化能力仅次于氟；

(2)OH可以直接与废水中的污染物反应将其降解为二氧化碳、水和无害物；

(3)由于羟基自由基的氧化能力很强，所以反应速度快，可以在较短的反应时间内达到处理要求；

(4)芬顿反应可以作为单独处理工艺，又可与其他处理工艺相结合，提供处理效率且能够降低处理成本。

Fenton 氧化法在废水处理中的应用具有其它方法无可比拟的优点，但由于过氧化氢价格昂贵，如果单独使用Fenton 试剂，则成本太高，所以在实践应用中通常与其他方法联用，如与混凝沉降法、生物法、活性炭法等联用，用于废水的预处理或最终深度处理，以取得良好效果。

加入Fenton试剂对废水进行预处理，是通过羟基自由基（·OH)与有机物的反应，使废水中难降解的有机物发生偶合或氧化，形成分子量较小的中间产物，从而改变它们的可生化性、混凝沉淀性和溶解性，然后通过后续的混凝沉淀法或生化法加以去除，可达到净化的目的。

一些工业废水，经物化、生化处理后，水中仍有少量难降解有机物未得以去除，当水质未能达到排放标准时，可采用 Fenton 氧化法对其进行深度处理。例如，处理染料废水采用中和生化法时，由于仍残留着生物难降解有机物，出水的 COD 和色度不能达标排放。而加入少量的Fenton 试剂，可以同时达到去除 COD 和脱色的目的，使出水达到国家排放标准。

OXIDATION DITCH PROCESS

As a mature activated sludge wastewater treatment process, the oxidation ditch process has been widely used throughout the country. It is a variant of the activated sludge process. Its aeration tank is a closed ditch type. Common oxidation ditch processes such as Obel oxidation ditch, Carrousel oxidation ditch, etc; So it is not similar to the traditional activated sludge process, it is a kind of circulating flow aeration ditch connected from end to end, in which sewage is infiltrated and purified.

The oxidation ditch process uses a continuous annular reaction tank as a biological reaction tank, in which the mixed liquid is continuously circulated through a closed aeration channel. Oxidation ditch is usually used under delayed aeration conditions. The oxidation ditch uses an aeration and agitation device with directional control to transfer the horizontal velocity of the substance in the reaction tank. The stirred liquid circulates in the closed channel. Oxidation ditch is generally composed of ditch body, aeration equipment, water inlet and outlet devices, diversion and mixing equipment. The plane shape of the ditch body is generally annular, or rectangular, L-shaped, circular or other shapes. The end faces of the ditch are mostly rectangular and trapezoidal.

PROCESS CHARACTERISTICS OF OXIDATION DITCH

(1) Simplified pretreatment

The hydraulic retention time and sludge age of oxidation ditch are higher than those of ordinary biological treatment plants. Suspended organics and dissolved organics can be completely removed at the same time, and the discharged excess sludge has been highly stabilized. Therefore, the oxidation ditch may not be equipped with a primary sedimentation tank, and the sludge does not need anaerobic digestion.

(2) Small floor area

Because the primary sedimentation tank, sludge digestion tank, and sometimes the secondary sedimentation tank and sludge return device are omitted in the process, the total floor area of the sewage plant can be reduced rather than increased.

(3) It has the characteristics of push flow pattern

The oxidation ditch has a plug flow characteristic, which makes the dissolved oxygen concentration form a concentration gradient along the length of the tank, forming aerobic, anoxic and anaerobic conditions. Through reasonable design and control of the system, better nitrogen and phosphorus removal effect can be achieved.

(4) Simplify process

The oxidation ditch and secondary sedimentation tank are combined to form an integrated oxidation ditch, and the oxidation ditch developed alternately in recent years no need use the secondary sedimentation tank, thus simplifying the treatment process.

氧化沟工艺

氧化沟工艺作为一种成熟的活性污泥污水处理工艺已在全国范围内得到广泛应用，它是活性污泥法的一种变型，其曝气池呈封闭的沟渠型，常见的氧化沟工艺例如：奥贝尔氧化沟、卡鲁塞尔氧化沟等等：所以它在水力流态上不同于传统的活性污泥法，而是一种首尾相连的循环流曝气沟渠，污水渗入其中得到净化。

氧化沟工艺利用连续环式反应池作生物反应池，混合液在该反应池中一条闭合曝气渠道进行连续循环。氧化沟通常在延时曝气条件下使用。氧化沟使用一种带方向控制的曝气和搅动装置，向反应池中的物质传递水平速度，从而使被搅动的液体在闭合式渠道中循环。氧化沟一般由沟体、曝气设备、进出水装置、导流和混合设备组成，沟体的平面形状一般呈环形，也可以是长方形、L形、圆形或其他形状，沟端面形状多为矩形和梯形。

氧化沟工艺特点

(1) 简化了预处理

氧化沟水力停留时间和污泥龄比一般生物处理法厂，悬浮有机物可与溶解性有机物同时得到较彻底的去除，排出的剩余污泥已得到高度稳定，因此氧化沟可不设初沉池，污泥不需要进行厌氧消化。

(2) 占地面积少

因为在流程中省略了初沉池、污泥消化池，有时还省略了二沉池和污泥回流装置，使污水厂总占地面积不仅没有增大，相反还可缩小。

(3) 具有推流式流态的特征

氧化沟具有推流特性，使得溶解氧浓度在沿池长方向形成浓度梯度，形成好氧、缺氧和厌氧条件。通过对系统合理的设计与控制，可以取得较好的脱氮除磷效果。

(4) 简化工艺

将氧化沟和二沉池合建为一体式氧化沟，以及近年来发展的交替工作的氧化沟，可不用二沉池，从而使处理流程更为简化。

SBR PROCESS INTRODUCTION

SBR is sequencing batch activated sludge process, which is called sequencing batch activated sludge process. It is an activated sludge wastewater treatment technology that operates in the way of intermittent aeration. It is mainly characterized by sequential operation and intermittent operation, and its core is SBR reaction tank, which integrates homogenization, primary sedimentation, biodegradation, secondary sedimentation, etc. It can be used in one tank without sludge return system. It is especially suitable for intermittent discharge and large flow change. SBR is a variant of the current activated sludge process. Its reaction mechanism and pollutant removal mechanism are basically the same as those of traditional activated sludge, except for its operation.

The operation mode of SBR consists of five basic processes: water inlet, reaction, sedimentation, water outlet and standby. A cycle is counted from the beginning of sewage inflow to the end of standby time. In a cycle, all processes are carried out successively in a reaction tank equipped with aeration or stirring devices. This operation cycle is repeated. Repeat to achieve the goal of continuous sewage treatment. Therefore, the sedimentation tank, return sludge pump and other devices necessary for traditional activated sludge method are not required.

The traditional activated sludge method is to set up different facilities in space for fixed continuous operation; SBR operates in a single reaction tank for different purposes in time.

OUTLET<br>INLET

CHARACTERISTICS OF SBR PROCESS

(1) It is not easy to produce sludge bulking, especially when the sewage enters the biochemical treatment unit and is maintained in the anaerobic state, which reduces SV1 (sludge index) and saves the power cost of aeration.

(2) The structure of the treatment structure is simple, and the equipment cost and operation management cost are less than those of the continuous type.

(3) In most cases, no flow regulating pool is required.

(4) The volume of aeration tank can also be reduced compared with continuous tank.

(5) If properly operated, the water quality can be better than that of continuous treatment; At the same time, it can realize biological nitrogen and phosphorus removal in a single tank.

SBR工艺介绍

SBR即序批式活性污泥法，全称为序列间歇式活性污泥法，是按照间歇曝气的方式来运行的活性污泥污水处理技术。它的主要特征是按照顺序运行和间歇操作，其核心是SBR反应池，该池集均化、初沉、生物降解、二沉等功能于一池，无污泥回流系统。尤其适用于间歇排放和流量变化较大的场合。SBR是现行的活性污泥法的一个变型，它的反应机制以及污染物质的去除机制和传统活性污泥基本相同，仅运行操作不一样。

SBR的操作模式由进水、反应、沉淀、出水和待机等5个基本过程组成。从污水流入开始到待机时间结束算做一个周期。在一个周期内，一切过程都在一个设有曝气或搅拌装置的反应池内依次进行，这种操作周期周而复始反复进行，以达到不断进行污水处理的目的。因此不需要传统活性污泥法中必需设置的沉淀池、回流污泥泵等装置。

传统活性污泥法是在空间上设置不同设施进行固定地连续操作；而SBR是在单一的反应池内，在时间上进行各种目的不同操作。

(1)不易产生污泥膨胀，特别是在污水进人生化处理装置期间，维持在厌气状态下，使得SV1（污泥指数）降低，而且还能节省曝气的动力费用。

(2)处理构筑物的构成简单，设备费、运转管理费也较连续式少。

(3)大多数情况下，不需要流量调节池。

(4)曝气池容积较连续式也可缩小。

(5)可得出比连续式更好的处理水质；同时可以实现单池生物脱氮、除磷的目的。

CASS PROCESS INTRODUCTION

CASS (Cyclic Activated Sludge System), also known as circulating activated sludge process, is developed on the basis of SBR, that is, a biological selector is added at the inlet end of the SBR reaction tank to achieve continuous water inflow (continuous water inflow during sedimentation and drainage periods) and intermittent drainage.

On the basis of Sequencing Batch Reactor (SBR), the reaction tank is designed into two parts along the length of the tank. The front part is the biological selection area, also known as the pre reaction area, and the rear part is the main reaction area. The rear part of the main reaction area is equipped with a lifting automatic skimming device. The whole process of aeration, sedimentation and drainage is in the same tank. Cyclic operation eliminates the secondary sedimentation tank and sludge return system of conventional activated sludge process; At the same time, continuous water inflow and intermittent drainage are available.

In the pre reaction area, microorganisms can quickly adsorb most of the soluble organic matters in the sewage through the fast transfer mechanism of enzymes, and experience a rapid accumulation process of high load substrate, which inhibits the growth of influent water quality, water volume and pH, and can effectively prevent sludge bulking; Then, a lower level is experienced in the main reaction zone. Substrate degradation process. CASS process integrates reaction, sedimentation, drainage and functions. The degradation of pollutants is a plug flow process in terms of time, while microorganisms are in the process of aerobic, anoxic and anaerobic periodic changes, so as to achieve the removal of pollutants, and also has good nitrogen and phosphorus removal functions.

Working principle of CASS method: A biological selection area is set in the front of the reactor, and a lifting automatic decanting device is set in the rear. Its working process can be divided into several stages: aeration, sedimentation, decanting and idling, which are carried out periodically. The sewage continuously enters the pre reaction area and enters the main reaction area through the bottom of the partition wall.

Under the condition of oxygen supply, the organic matter will be degraded by microorganisms in the tank. The operation parameters can be adjusted according to the inlet water quality.

CASS工艺介绍

CASS(Cyclic Activated Sludge System)，又称为循环活性污泥工艺，这是在 SBR的基础上发展起来的，即在 SBR 反应池内进水端增加了一个生物选择器，实现了连续进水（沉淀期、排水期仍连续进水），间歇排水。

在序批式活性污泥法(SBR)的基础上，反应池沿池长方向设计为两部分，前部为生物选择区也称预反应区，后部为主反应区，其主反应区后部安装了可升降的自动撇水装置。整个工艺的曝气、沉淀、排水等过程在同一池子内周期循环运行，省去了常规活性污泥法的二沉池和污泥回流系统同时可连续进水，间断排水。

在预反应区内，微生物能通过酶的快速转移机理迅速吸附污水中大部分可溶性有机物，经历一个高负荷的基质快速积累过程，这对进水水质、水量、pH生长起到抑制作用，可有效防止污泥膨胀：随后在主反应区经历一个较低负荷的基质降解过程。CASS工艺集反应、沉淀、排水、功能于一体，污染物的降解在时间上是一个推流过程，而微生物则处于好氧、缺氧、厌氧周期性变化之中，从而达到对污染物去除作用，同时还具有较好的脱氮、除磷功能。

CASS工作原理：在反应器的前部设置了生物选择区，后部设置了可升降的自动灌水装置。其工作过程可分为曝气、沉淀、灌水、闲置几个阶段，周期循环进行。污水连续进入预反应区，经过隔墙底部进入主反应区，在保证供氧的条件下，使有机物被池中的微生物降解。根据进水水质可对运行参数进行调整。

IMPROVED A2O PROCESS

A2O is the abbreviation of Anaeroxic-Anoxic-Oxic. A2O biological nitrogen and phosphorus removal process is a combination of traditional activated sludge process, biological nitrification and denitrification process and biological phosphorus removal process.

The biological tank is divided into anaerobic section, anoxic section and aerobic section through the arrangement of aeration device. propeller (anaerobic section and anoxic section) and return channel. In this process flow, BOD5, SS and nitrogen and phosphorus in various forms will be removed one by one. In the activated sludge of the A2O biological nitrogen and phosphorus removal system, the bacteria group is mainly composed of nitrifying bacteria, denitrifying bacteria and phosphorus accumulating bacteria.

In the aerobic section, nitrifying bacteria convert the ammonia nitrogen and organic nitrogen in the influent into ammonia nitrogen, which is converted into nitrate through biological nitrification;

In the anoxic section, denitrifying bacteria convert the nitrate brought in by internal reflux into nitrogen and escape into the atmosphere through biological denitrification, so as to achieve the purpose of nitrogen removal;

In anaerobic section, phosphorus accumulating bacteria release phosphorus and absorb easily degradable organics such as low-grade fatty acids; In the aerobic section, phosphorus accumulating bacteria absorb phosphorus in excess and remove phosphorus through the discharge of excess sludge

PROCESS CHARACTERISTICS

① The organic combination of anaerobic, anoxic and aerobic three different environmental conditions and microbial communities can simultaneously remove organic matters, nitrogen and phosphorus.

② In the process of simultaneous deoxidation, phosphorus removal and organic matter removal, this process is the simplest, and the total hydraulic retention time is also less than other similar processes.

③ Under the anaerobic anoxic aerobic alternative operation, filamentous bacteria will not multiply in large numbers, SVI is generally less than 100, and sludge bulking will not occur.

④The phosphorus content in sludge is high, generally more than 2.5%.

INTRODUCTION TO IMPROVED A2O PROCESS

The characteristic of the improved A2O is that a pre anoxic tank is added in front of the anaerobic tank to better achieve the effect of nitrogen and phosphorus removal, so as to reach the national first-class A standard. This process is a good choice for wastewater with high phosphorus content.

INVERT A2O PROCESS AND ITS CHARACTERISTICS

The rationality of anaerobic, anoxic and aerobic layout of traditional A2/O process is questionable. In terms of carbon source distribution, it always gives priority to the need for phosphorus release, placing the anaerobic zone in the front of the process and the anoxic zone behind. This method is based on the premise of sacrificing the denitrification rate of the system. But phosphorus release itself is not a phosphorus and nitrogen removal process. The ultimate purpose of. As far as the final purpose of the process is concerned, it is worth studying whether it is really beneficial and what are the advantages and disadvantages of putting the anaerobic zone in front. Based on the above understanding, they proposed a new carbon source distribution mode for the conventional phosphorus and nitrogen removal process. The anoxic zone is placed at the front of the process, and the anaerobic zone is placed behind it, namely the so-called inverted A2/O process, as shown in the figure below.

INVERT A2O PROCESS FLOW CHART

FEATURES OF INVERTED A2O PROCESS

① After anaerobic phosphorus release, the phosphorus accumulating bacteria directly enter the aerobic environment with high biochemical efficiency, and the phosphorus absorption power formed under anaerobic conditions can be more fully utilized, with the advantage of "hunger effect";

② All sludge involved in the reflux are allowed to experience complete phosphorus release and absorption processes, so it has the advantage of "group effect" in phosphorus removal;

③ The anoxic section is located at the first end of the process, allowing denitrification to obtain carbon source preferentially, thus further strengthening the denitrification capacity of the system;

④ With proper measures taken in the project, the return sludge and intemal circulation can be combined into an external retum system, so the process is simple and suitable for promotion.

改良A20工艺介绍

改良A20的特点就是在厌氧池的前面加上了一个预缺氧池，以更好的达到脱氮除磷的效果，从而达到国家一级A的标准。对于含磷较高的污水，该工艺是一个不错的选择。

倒置A20工艺介绍

传统A2/0工艺厌氧、缺氧、好氧布置的合理性值得怀疑。其在碳源分配上总是优先照顾释磷的需要，把厌氧区放在工艺的前部缺氧区置后。这种作法是以牺牲系统的反硝化速率为前提的。但释磷本身并不是除磷脱氮工艺的最终目的。就工艺的最终目的而言把厌氧区前置是否真正有利，利弊如何，是值得研究的。基于以上认识，他们对常规除磷脱氮工艺提出一种新的碳源分配方式缺氧区放在工艺最前端，厌氧区置后，即所谓的倒置A2/0工艺见下图。

MEMBRANE BIOREACTORMBR膜生物反应器

MBR is a new type of efficient sewage treatment process that combines efficient membrane separation technology with traditional activated sludge process. It uses MBR flat membrane modules with a unique structure to place them in the aeration tank. The water after aerobic aeration and biological treatment is pumped out after filtering through the filter membrane by the pump. It uses membrane separation equipment to intercept and retain the activated sludge and macromolecular organic substances in the biochemical reaction tank, eliminating the secondary sedimentation tank. As a result, the concentration of activated sludge is greatly increased. The hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while the refractory substances are continuously reacted and degraded in the reactor.

PLATE AND FRAME FILTER PRESS 板框压滤机

The plate and frame filter press is an intermittent solid-liquid separation equipment. Under the pressure of the feed pump, the feed liquid is loosened and tightened in each filter chamber to separate the solid-liquid through the filter medium. The utility model has the advantages of large filtering driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and high conditioning drug consumption.

板框压滤机是一种间歇式固液分离设备，在输料泵压力作用下，将料液松紧各滤室，通过过滤介质，将固液分离。具有过滤推动力大、滤饼的含固率高、滤液清澈、固体回收率高、调理药品消耗量上等优点。

Plate and frame filter press is used for separating solid and liquid. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has higher solid content and excellent separation effect. The basic principle of solid-liquid separation is that the mixed liquid flows through the filter medium (filter cloth), the solid stays on the filter cloth, and gradually accumulates on the filter cloth to form filter mud cake. The filtrate will permeate the filter cloth and become a clear liquid without solids.

板框压滤机用于固体和液体的分离。与其它固液分离设备相比，压滤机过滤后的泥饼有更高的含固率和优良的分离效果。固液分离的基本原理是：混合液流经过滤介质（滤布)，固体停留在滤布上，并逐渐在滤布上堆积形成过滤泥饼。而滤液部分则渗透过滤布，成为不含固体的清液。

With the process of filtration, filter cake filtration starts, mud cake thickness gradually increases, and filter resistance increases. The longer the filtration time is, the higher the separation efficiency is. The specially designed filter cloth can intercept particles with a diameter less than 1 μ M particles. In addition to excellent separation effect and high solid content of mud cake, the filter press can also provide a further separation process: during the filtering process, the filter mud cake can be effectively washed in combination, so that valuable substances can be recovered and high-purity filter mud cake can be obtained.

MULTI-DISK SCREW PRESS 叠螺式污泥脱水机

The stacked snail sludge dehydrator is composed of a fully automatic control cabinet, a flocculation modulation tank, a sludge thickening and dewatering body and a liquid collecting tank. It can achieve efficient flocculation under the condition of fully automatic operation, and continuously complete the sludge thickening and pressing dehydration, and finally return or discharge the collected filtrate.

叠螺污泥脱水机由全自动控制柜、絮凝调制槽、污泥浓缩脱水本体及集液槽组成，可在全自动运行的条件下，实现高效絮凝，并连续完成污泥浓缩和压榨脱水工作，最终将收集的滤液回流或排放。

When the screw rotates, it drives the dynamic and static rings around the circumference of the spiral shaft to produce relative movement, so that the filtrate can be filtered out quickly in the relatively moving ring gap. At the same time, the volume between the spiral shaft and the ring is continuously reduced to increase the internal pressure. By adjusting the back pressure plate, the solid content of the mud cake is continuously increased. Under the continuous thrust of the spiral shaft, the filtrate is continuously separated from the outside flow, and the sludge is dehydrated and discharged.

当螺旋转动时，带动螺旋轴圆周外围的动、静环片产生相对移动，使滤液在相对游动的环片间隙中快速滤出，同时利用螺旋轴与环片间体积的不断缩小，增大内压力，并通过调节背压板，使泥饼含固量不断提高，在螺旋轴连续推力下，使滤液连续分离外流，污泥脱水排出。

The spiral sludge dehydrator adopts mechanical extrusion for dehydration, and does not need a large machine body such as a roller, so the machine is designed to be quite light; The machine body is almost made of stainless steel. The only parts to be replaced are the spiral shaft and the traveling ring, which have a long service life and are durable. The equipment covers a small area and is more practical. The sludge dewatering rate of the screw type sludge dehydrator is as high as 80%. It is fully automatic and does not require manual operation, saving benefits and costs for the enterprise.

叠螺污泥脱水机采用机械挤压脱水，无需滚筒等大型机体，因而该机设计得相当轻巧；机体几乎全部采用不锈钢材质，更换部件只有螺旋轴和游动环，使用寿命长，经久耐用。设备占地面积小、实用性更强。叠螺式污泥脱水机污泥脱水率高达80%，全自动运行，不需要人工操作，为企业节省利益成本。

The first stage three-phase separator is mainly used to separate biogas and water, the second stage three-phase separator is mainly used to separate sludge and water, and the influent and return sludge are mixed in the first anaerobic reaction chamber. The first reaction chamber has a great ability to remove organics. The wastewater entering the second anaerobic reaction chamber can continue to be treated to remove the residual organics in the wastewater and improve the effluent quality.

其构造的特点是具有很大的高径比，一般可达4-8，反应器的高度达到20m左右。整个反应器由第一厌氧反应室和第二厌氧反应室叠加而成。每个厌氧反应室的顶部各设一个气、固、液三相分离器。第一级三相分离器主要分离沼气和水，第二级三相分离器主要分离污泥和水，进水和回流污泥在第一厌氧反应室进行混合。第一反应室有很大的去除有机物能力，进入第二厌氧反应室的废水可继续进行处理，去除废水中的剩余有机物，提高出水水质。

TECHNICAL CHARACTERISTICS

应用特点

1. High volume load

Due to the strong internal circulation, the Ic reactor has good mass transfer effect and large biomass. Its volume load is much higher than that of ordinary UASB reactors, generally about 3 times higher.

2. Save infrastructure investment and floor area

The volume load of the Ic reactor is about 3 times higher than that of the ordinary UASB reactor, and it is about 1/4-1/3 of the floor area of the ordinary UASB reactor, so the infrastructure investment of the reactor can be reduced.

3. Strong impact load resistance

The Ic reactor realizes its own internal circulation, and the circulation volume can reach 10-20 times of the influent water. Because the circulating water and the influent water are fully mixed at the bottom of the reactor, the concentration of organic matter at the bottom of the reactor is reduced, thereby improving the impact load resistance of the reactor; at the same time, the large amount of water also makes the sludge at the bottom evenly dispersed, ensuring the waste water. The full contact reaction between organic matter and microorganisms increases the processing load.

4. Good water outlet stability

Because the IC reactor is equivalent to the series operation of the upper and lower UASB and EGSB reactors, the lower reactor has a high organic loading rate and acts as a "coarse" treatment, and the upper reaction has a low loading rate and acts as a "fine" treatment The effect is to make the effluent water quality good and stable.

1、具有很高的容积负荷

1c反应器由于存在着强大的内循环、传质效果好、生物量大。其容积负荷远比普通的UASB反应器高，一般可高出3倍左右：

2、节省基建投资和占地面积

Ic 反应器比普通UASB 反应器高3 倍左右的容积负荷，是普通UASB 反应器占地面积的1/4-1/3 左右，所以可降低反应器的基建投资。

3、抗冲击负荷能力强

1c反应器实现了自身的内循环，循环量可达进水的10-20倍。因为循环水与进水在反应器底部充分混合，使反应器底部的有机物浓度降低，从而提高了反应器的耐冲击负荷能力；同时大水量也使底部污泥得以均散，保证了废水中的有机物与微生物的充分接触反应，提高了处理负荷。

4、出水稳定性好

因为IC反应器相当于上下两个UASB与EGSB反应器的串联运行，下面一个反应器具有很高的有机负荷率，起“粗”处理作用，上面一个反应的负荷率低，起“精”处理作用，使出水水质好且稳定。

UASB REACTORUASB 反应器

The upper part of the UASB reactor is equipped with a gas, solid and liquid three-phase separator, and the lower part is the sludge suspension layer area and the sludge bed area. The wastewater is uniformly pumped into the sludge bed area from the bottom of the reactor, and fully contacts with the anaerobic sludge. , organic matter is decomposed into biogas by anaerobic microorganisms. Liquid, gas and solid form a mixed liquid flow and rise to the three-phase separator, so that the three are well separated, so that more than 80% of the organic matter is converted into biogas, and the wastewater treatment process is completed.

UASB反应器的上部设置气、固、液三相分离器，下部为污泥悬浮层区和污泥床区，废水由反应器底部均匀泵入污泥床区，与厌氧污泥充分接触反应，有机物被厌氧微生物分解成沼气。液体、气体与固体形成混合液流上升至三相分离器，使三者很好的分离，使80%以上的有机物被转化为沼气，完成废水处理过程。
