Abstract:

With the continuous development of China's aquaculture industry, the improvement of aquaculture tailwater treatment technology becomes more and more urgent. In recent years, with the continuous expansion of the scale of industrialized aquaculture, untreated aquaculture tailwater not only increases the mortality rate of aquatic organisms in the surrounding environment, but also leads to eutrophication of surrounding water bodies, thereby limiting the development of aquaculture industry and affecting industrial upgrading. The current research on tailwater treatment process, the technologies for screening of water purification materials and ozone disinfection, and the current situation of constructed wetland technology were summarized in this study, and on this basis, the prospects were put forward to provide reference for optimizing the water purification mode and realizing ecological priority and green development of the aquaculture industry.

Key words: tailwater treatment, water purification materials, ozone disinfection, constructed wetland technology
