Background technique

At present, most lakes and reservoirs in my country are polluted to varying degrees, some water bodies are in a state of eutrophication, and algal blooms occur from time to time. When algal blooms break out or water body eutrophication is severe, the algae content in the water body is high and covers the middle and upper layers of the water body, which makes the oxygen content of the water body drop and the organisms in the water body die. Some algae such as Microcystis release algae toxins into the water body, which affects the biological safety of the water body and transmits hazards through the food chain, seriously affecting the ecology of the water body and human health. Transferring excessive algae out of the water body can reduce the nitrogen and phosphorus content in the water body, and at the same time improve the transparency of the water body. Therefore, how to effectively remove harmful algae in the water body and restore the good ecological environment of the water body is an urgent problem to be solved in water body governance.
