摘　　要：随着城镇化的快速发展,我国城镇污水收集处理的短板日益突出。污水管网建设改造滞后,分流制、合流制并存,雨、污水管网破损老旧,排水能力不足,部分污水漏接、错接,导致城镇污水收集率较低,现有合流制管道在雨天溢流导致水体污染。以嘉祥县老城区住宅小区雨、污分流改造为例,介绍合流制系统改造的具体方案及改造要点。With the rapid development of urbanization,the shortcomings of urban sewage collection and treatment in China are becoming increasingly prominent.The construction and renovation of sewage pipe networks are lagging behind,with both separate and combined systems coexisting.The rainwater and sewage pipe networks are damaged and old,with insufficient drainage capacity.Some sewage is leaking or misconnected,resulting in a low urban sewage collection rate.The existing combined system pipelines overflow on rainy days,causing water pollution.Taking the rainwater and sewage diversion renovation of residential communities in the old urban area of Jiaxiang County as an example,this article introduced the specific plan and key points of the combined sewer system renovation.
