At higher temperatures, endogenous pollutants release a large amount of nitrogen and phosphorus, causing water eutrophication. When a large amount of organic matters in the bottom mud are decomposed by aerobic microorganisms, the dissolved oxygen in the water is consumed at a high speed, and the anaerobic microorganisms and the facultative microorganisms in the water decompose the organic matters to generate a large amount of hydrogen sulfide and ammonia, so that the water body generates odor. Because the dissolved oxygen content in water is low, aquatic plants, metazoan, fishes, shrimps and amphibians are few, a benign food chain is not available, the ecological environment of the water body is damaged, the self-cleaning capacity of the water body is small, and the river landscape is poor. In general river sewage treatment devices, sewage in rivers needs to be moved through a pump body, but the effective utilization of the kinetic energy of the sewage in the treatment process is usually neglected in the traditional working mode.
