At present, eutrophication of closed water bodies is a global problem of water environment pollution. About 80% of closed water bodies in China have eutrophication problems. Existing treatment methods have high cost and secondary pollution problems. Therefore, the use of photocatalytic technology to treat inorganic nitrogen, organic pollutants and algae in the surface of closed water bodies can better avoid the eutrophication of water bodies. Occurs to achieve the purpose of maintaining the water environment.
