Aquacultural tail water treatment

通過對水產養殖過程中產生的殘餌、糞便等污染水體進行高效處理，利用物理過濾、化學吸附、植物過濾及微生物作用等多種方法，顯著降低水產養殖尾水中的氮、磷等營養元素含量，去除大部分生化需氧量和微小懸浮物，達到凈化水質、保護環境的目的。并通過尾水的循環利用,，實現工廠化循環水養殖，促進水產養殖業的綠色高效發展。

Through efficient treatment of contaminated water bodies such as residual bait and feces generated in the aquaculture process, physical filtration, chemical adsorption, plant filtration and microbial action are used to significantly reduce the content of nitrogen, phosphorus and other nutrients in aquaculture tail water, remove most of the biochemical oxygen demand and small suspended solids, and achieve the purpose of purifying water quality and protecting the environment. And through the recycling of tail water, to realize the factory circulating water aquaculture, to promote the green and efficient development of aquaculture industry.
