【Abstract】 Biofloc Technology(BFT) uses metabolic action of microorganisms to treat nitrogenous wastewater efficiently, which has a unique advantage in aquaculture water treatment. In this paper, the research progress of BFT in aquaculture water treatment and a variety of treatment mechanisms on harmful nitrogen in aquaculture water were reviewed. The effects of different culture conditions on the structure of microbial community in the nitrogen transformation process of aquaculture wastewater were discussed. Some process control and management measures of BFT were put forward. Finally, the existing problems of technology application are analyzed, and the future research directions are put forward, which provide reference for its application in aquaculture water treatment.更多还原
