[0002] In the treatment of water bodies, the method of using ecological floating islands to plant plants to treat water bodies is a method with relatively low cost among existing methods. Ecological floating islands have the function of cultivating aquatic plants. For eutrophic water quality, using the principle of ecological engineering, they degrade COD, nitrogen, and phosphorus in water to reduce the pollution load in the water body and improve the water transparency.
