The urban black and odorous water body is a water environment problem which is reflected by common people, so that the urban living environment is damaged, and the urban image is seriously influenced.
Along with the rapid development of urban economy in China, the urban scale is increasingly expanded, and urban environment infrastructures are gradually insufficient. After a large amount of organic pollutants, organic reduction nitrogen, phosphorus and other external pollutants enter the water body, the aerobic rate is greater than the oxygen-rich rate in the oxidative decomposition process, the DO of the water body is approximately reduced, the water body is converted into an anoxic or anaerobic state, so that anaerobic bacteria are propagated in a large amount, organic matters in the water body are promoted to be decomposed, putrefied and fermented, particle suspended matters are formed to float in the water body, and meanwhile, malodorous gases such as methane, hydrogen sulfide and the like are generated to escape from the water surface and enter the atmosphere, so that the water body is black and odorous. The black and odorous water body not only damages urban living environment, but also seriously affects urban image, and the problem of how to effectively inhibit the black and odorous water body and recover the self-cleaning function of the water body is urgently solved in the control of water environmental pollution. At present, the black and odorous water body is generally treated by adopting an artificial aeration method, and DO in the water is increased by adopting an artificial method, so that the black and odorous water body is changed into a water body rich in oxygen, and the self-purification capacity of the water body is improved. However, the existing treatment method has high technical cost and poor effect, and still has room for improvement.
