Abstract:
Taking the rainwater and sewage diversion transformation of residential zones as the research object, this paper focuses on the implementation of highquality “zero direct discharge of sewage” construction in residential zones of Hangzhou. From the aspects of accurate investigation of sewage pipe network in residential zones, construction and transformation of rainwater/sewage diversion in pipe network, implementation of dynamic supervision of informatization operation and maintenance, the construction and management of sewage pipe network have achieved the goal of greatly improving COD concentration and centralized collection rate of sewage in the sewage drainage pipes of residential zones. Therefore, we introduce the construction experience of “zero direct discharge of sewage” in residential zones of Hangzhou, which provides reference and replicable experience for sewage treatment of other residential zones in China.
