Methods such as placing chemicals in the river are quick to take effect, but have poor sustainability, especially for flowing river water, which requires regular placement of chemicals, which is too expensive and not economically feasible. Methods such as dredging, intercepting sewage, and changing water do not establish the self-purification capacity of the river water body, that is, they do not establish a water ecosystem formed and strengthened by technical behavior. After maintaining a short period of cleanliness, the river water becomes black and smelly again due to eutrophication of the water body formed by natural pollution and artificial pollution, and the purification treatment results are discounted to a certain extent. Therefore, it is urgent to design a combined ecological filter dam to solve the above problems. Summary of the invention
