摘要：
In this study, we constructed aquatic microcosms, including four experimental groups, to simulate eutrophic lakes. Using polyurethane sponges as artificial substrates to support periphyton, we conducted a systematic study of the effect of periphyton on the water quality of eutrophic lakes by monitoring water-quality indexes including TN, TP, and NTU. The results show that periphyton can effectively degrade N and P in these bodies of water, reduce NTU and the concentration of Chl-a, and restore the aquatic environment. Periphyton can also promote the formation of the DO-Chl-a-NTU-TN-TP synergistic system, which can provide a basis for the comprehensive management of eutrophic lakes. Periphyton can also effectively improve the water quality of eutrophic lakes, and its positive impact on lake ecosystems cannot be ignored during the treatment of eutrophic lakes.
