小区雨污混接改造设计探讨

城市水环境治理， 重点在源头， 由于早期设计不合理、施工不规范等历史原因，现状小区内部雨污水排放无序，造成小区内部环境不佳、 市政雨污水管网及污水处理设施不能充分发挥效益。在国家及各地区大力改善水环境的背景下， 以上海某区雨污混接改造工程为案例，结合设计及施工过程中遇到的情况， 回顾总结小区内部雨污混接存在的问题， 提出相应的解决措施。

Discussion on Reconstruction Design of Rainwater and Sewage Mixing in Housing Estate

Urban water environment treatment focuses on the source. Due to the unreasonable design and non-standard construction in the early stage and other historical reasons, the internal rainwater and sewage discharge in the current housing estates is disordered, which results in poor internal environment of the housing estates, and the municipal rainwater and sewage pipe networks and the sewage treatment facilities cannot give full play to the benefits. Under the background of the national and regional efforts to improve the water environment, taking a rainwater and sewage mixing reconstruction project in a housing estate of Shanghai as an example, combined with the situations encountered in the process of design and construction, the problems existing in the rainwater and sewage mixing within the housing estate are reviewed and summarized, and the relevant solutions are proposed.
