Whenever summer comes, these eutrophic water bodies often have cyanobacteria "blooms". Once a cyanobacteria "bloom" breaks out, in order to ensure that the water body is not polluted, it is necessary to collect and treat the cyanobacteria in the water body. At present, the method of collecting blue-green algae in the water body mainly adopts the setting of blue-green algae prevention and control floating dams on the water surface along the water body. This cyanobacteria prevention and control floating dam is connected by multiple floating bodies. This cyanobacteria prevention and control floating dam is placed on the water surface all year round to intercept and guide the cyanobacteria on the water surface for subsequent collection and treatment of cyanobacteria.
