Building an equipment room on a river bank, introducing two microorganism culture tank bodies 52, installing a stirrer 53, an inflator pump and a corresponding delivery pump 54, and communicating the delivery pump 54 with 5 paths of half-section ecological filter walls 72 and 1 path of full-section ecological filter wall 71 through multi-channel pipelines;

the aeration fan 63 is started to supply air towards the aeration head 62, so that the artificial waterweed filter layer 6 is assisted to proliferate microorganisms, the microorganism culture tank body 52 is used for culturing microorganisms and supplementing a large amount of microorganisms for 5 paths of half-section ecological filter walls 72 and 1 path of full-section ecological filter wall 71, the 5 paths of half-section ecological filter walls 72 and the 1 path of full-section ecological filter wall 71 are matched with the multiple artificial waterweed filter layers 6 to filter flowing river water in the river channel 7 layer by layer, river floating garbage, large particle impurities and the like are intercepted, organic pollutants are degraded, the turbidity of the water body is reduced, the cleanliness of the river water is improved, and the river pollution is effectively treated.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
