Aquacultural tail water treatment

通过对水产养殖过程中产生的残饵、粪便等污染水体进行高效处理，利用物理过滤、化学吸附、植物过滤及微生物作用等多种方法，显著降低水产养殖尾水中的氮、磷等营养元素含量，去除大部分生化需氧量和微小悬浮物，达到净化水质、保护环境的目的。并通过尾水的循环利用,，实现工厂化循环水养殖，促进水产养殖业的绿色高效发展。

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.
