住宅小区雨污分流改造方案研究

由于各种原因,上海市分流制排水地区目前仍然存在着不同程度的雨污混接现象,导致大量未经处理的污水直接通过雨水管网排向了周边河道水体,对河道水体造成了环境污染.城市内涝与黑臭水体治理的根本措施是控源截污,而控源截污的首要工作是全面推进雨污分流改造工作.以上海市某地区小区雨污分流改造工程为例,结合存在的雨污混接现象以及设计施工过程中遇到的问题,探讨在雨污分流改造中的技术措施.

Research on Separation Reconstruction Scheme of Rainwater and Sewage in Residence Community

Due to various reasons, there are still different degrees of rainwater and sewage mixing phenomenon in the separate-system drainage area of Shanghai, which results in a large number of untreated sewage directly discharged to the surrounding rivers through the rainwater pipe network so that the river environment is polluted. The fundamental measures of urban waterlogging and black and odorous water body treatment are to control the source and intercept the sewage. The primary work of controlling source and intercepting sewage is to comprehensively promote the reconstruction of rainwater and sewage separation. Taking the rainwater and sewage separation reconstruction project in a residence community of Shanghai as an example, combined with the existing rainwater and sewage mixing phenomenon and the problems encountered in the design and construction process, the technical measures in the separation reconstruction of rainwater and sewage are discussed.
