GuangdongLESSoAgricultural FacilitiesTechnology Co.,Ltd.
Guangdong Lesso Agricultural Facilities Technology Co., Ltd., a wholly-owned subsidiary of China LESSO Group Holdings Limited, mainly specializes in the development and promotion of standardized agricultural facilities. The products that the company has developed to date include integrated shore-based aquaculture tail water treatment systems, industrialrecirculating aquaculture systems,intelligent integrated machines of water and fertlizer, high-pressure sprayers, as well as energy-saving and noise-reducing aerators. The company aims to achieve a lower carbon and green power agriculture and explore the models of multiple and high production in a single piece of land by combining fishery-solar and agricultural-solar hybrid projects.
Guangdong Lesso Agricultural Facilities Technology Co., Ltd. holds dozens of patents for aquaculture and tail water treatment systems,among which the integrated shore-based aquaculture tailwater treatmentsystem,developedbycollaborativeresearchand development,was included in the Recommended Models of ComprehensiveTreatment Technologies for Aquaculture Tail Water in Guangdong Province. The cumulative area of fishpond aquaculture tail water treatment projects served by the company in thePearl River Delta area has now exceeded 10o,000 mu (approximately 66.67\ k m^{2})

Product Strengths
Efficient operation
Thedailytreatmentcapacityofthe aquaculturetailwaterpurificationtreatment system isashigh as 2500~\mathfrak{m}^{3} andthe system can be used to effectively treat and discharge aquaculture tail water up to therequiredstandards.
Low operating costs
Reagents maynot berequiredwhenthe aquaculturetailwaterpurificationtreatment system is running. Since the equipment has a relatively low power consumption, its main operating cost is only electricity expenses, resulting in integrally low operational costs.
Small occupied area
The aquaculture tail water purification treatment system occupies an area ranging from21to 63 ~m^{2} andcanbeplaced between pond banks for use. Its footprint ismuchsmaller thanthatofthe three-pond-two-dam tailwater treatment system
Simple operation, and easy maintenance
Allfunctionalvalves intheaquaculture tail waterpurificationtreatmentsystemare controlled by automatic timers,with no need for manual operation.The system is designed with a buit-in backwashing function, providing easydailycleaningandmaintenance.
Low cost per unit area
The adoptionof theequipment cansolve the critical issues of fishpond tailwater treatment accordingtostandardrequirements. Its investment cost requires only CNY 2,000 to 2,500 per mu (a traditional Chinese unit of area,approximately equal to 666.67~\mathsf{m^{2}}) whichissignificantlylower than thatofother tailwater treatmenttechnologies.
Flexible combinations
The aquaculture tail water purication treatment system can improve its treatment capacity of tail water by adding supporting combinations according towater quality requirements,in order tomeetmostwaterqualityrequirements for tail water discharge.
Thesystemextracts thetailwater into the equipment,and the water thenisdirected into the protein skimmer.The protein skimmer utilizes the air flotation method to generate a largenumberofmicrobubblesinthewaterandallowthesemicrobubblestoadhere to the suspended particles in the water.Once the particles are attached to the bubbles, the floating flocs that have an apparent density less than that of water are formed.These floating flocsrise to the water surface,andform a scum layer that needs tobescraped off;inthis way,thesuspendedparticles areremoved from thewater.
Thesystemusesabiofilmtechnologytoimmobilize aerobicmicroorganismsthrough membranes,and it also utilizes the metabolism of the microorganisms to consume organics in sewage.The application of this technology increases the surface area of microorganisms, and ismore efficient in actual sewage disposal.At the same time,the tailwaterisfurther treatedby theA-A-Omicroorganismnitrogenandphosphorusremovalfilter.After thetail water enters into the fiter,it firstpasses into the underlyingactivated sludge treatment area. Inordertoincrease thediverseenvironmentof theactivatedsludgearea,thesystemis provided with an anaerobic-anoxic-oxic generator to regularly supplement the tail water with oxygen，create ananaerobic,anoxic andoxic environment,andalsoreplenish carbon sources for anaerobic microorganisms.Subsequently,the tail water is further treated through thebiologicalfilteringmembranes.Finally,the tailwaterisdisinfected byultraviolet andozone beforebeingdischarged，andrecycledforreuse.
