The pollution sources of the water body mainly come from industrial wastewater, domestic sewage, wind sand dust, dirt carrying and the like. When the total amount of pollutants entering the water body exceeds the self-purification capacity of the dissolved oxygen content in the water body, the total dissolved oxygen in the water body is rapidly consumed, so that the water body is in an anoxic or even anaerobic state, and simultaneously, the ammonia nitrogen content is greatly increased, thereby causing the algae to breed in a large amount, leading the water body to present eutrophication, leading the transparency of the water body to be sharply reduced, and even leading the phenomenon of blackening and smelling.

Ten items of water are mainly used for treating urban river channel, and the problems of eliminating black and odorous river channels and improving the landscape appearance of the river channels are mainly solved in river treatment.

The existing urban river treatment technology in China mainly comprises the following steps: the water changing and water adjusting, the artificial aeration technology, the wetland ecological technology, the ecological floating bed technology and the like are adopted, frequent water changing and water adjusting difficulty is high, the existing ecological wetland and ecological floating bed technology need to occupy certain bank line space and water surface space, certain difficulty is brought to urban river water body cleaning, river channel dredging and river channel management, and the factors become bottleneck problems in river channel management in China.
