Study on the Application of Bio-flocs Technology in Tail Water Treatment

Abstract

In aquaculture, the deposition of biological manure and residual bait in water can cause water pollution. If the discharged aquaculture tail water is not treated in time, the surrounding water environment will be affected and the quality of aquaculture organisms will be reduced. Controlling inorganic nitrogen by controlling the carbon-nitrogen ratio is a potential aquaculture system control method. This method can effectively reduce the accumulation of inorganic nitrogen in ponds, convert ammonia and nitrite nitrogen in water into proteins for culture organisms, and inhibit the growth of harmful microorganisms. This paper discusses the research development of bio-flocs technolgy at home and abroad, how to treat tail water with maximum efficiency in order to solve the problems of debris and feed retention in aquaculture water and realize the reuse of bait, and purifying water quality.
