Background technique

In recent years, with the rapid development of industrial mariculture characterized by high density and the increasing pollution of the aquaculture environment, the pollution degree of mariculture water far exceeds the purification capacity of the water itself. After the residual feed and fish excrement in the artificial mariculture process are discharged into the offshore, they will be rapidly decomposed and transformed under suitable conditions, producing a large amount of nitrogen and phosphorus compounds. These large amounts of nitrogen and phosphorus wastes will lead to the excessive accumulation of nitrogen and phosphorus pollutants in the water, thereby causing the pollution of seawater itself and even the deterioration of water quality. Especially in the intensive areas of mariculture, the pollutants in the discharged wastewater will have an impact on the marine environment. The superimposed effect occurs, which can easily lead to the occurrence of offshore eutrophication and red tide.
