There is a strong contrast between urban river pollution and the need to improve the quality of residents' living environment. Comprehensively eliminating urban black and odorous water bodies has become one of the important tasks of urban water management. In this paper, through the application of biological aerated filter in environmental biology, the filter technology will be applied to the purification of urban domestic sewage. Taking River B in city a in the South as the research object, the effects of different filling filter materials, biofilm hanging time of biological aerated filter and other factors on the treatment effect will be studied through a small-scale test system, The actual operation effect of the combined process of multi-stage filtration and biological aerated filter for the treatment of urban black and odorous water is verified by field tests.
