Study on Typical Rectification Cases of Sewage Outfalls into Environmental Water Bodies in the Urban Built-up Areas
In order to continuously optimize and improve the level of rectification and supervision of sewage out-falls into environmental water bodies,this paper takes the inspection and rectification of Yangtze River sewage outfalls into environmental water bodies in Gulou District,Nanjing City as an example for analysis and study.The typical types of sewage outfalls into environmental water bodies in urban built-up areas are urban rainwater sew-age outfalls and front pool of the pump-station sewage outfalls.In addition to cleaning,dredging and repairing the rainwater and sewage diversion pipelines,the rectification of the urban rainwater sewage outfalls should also solve the problem of direct sewage discharge caused by the mixing of balcony sewage in old residential areas;The front pool of urban drainage pump stations adopts in-situ ecological treatment processes such as assembled wetlands,which can effectively solve the problem of direct discharge of micro-polluted wastewater in the front pool.The rectification experience of these typical cases has exemplary and guiding significance for the next step of urban built-up areas to carry out full caliber sewage outfalls into environmental water bodies inspection and rectifica-tion work.
