摘　　要：城市排水系统是城市公用设施的重要组成部分,是保障城市运行的“生命线”。老城区排水系统大多仅有一套排水系统,同时排水管道规格小、雨水口堵塞严重、设施老化,雨污混流严重,甚至污水外溢,严重影响城市形象。文章以某老城区为例,通过阐述某老城区排水系统存在的雨污混乱问题,提出雨污分流改造要遵循可持续发展、与现状相结合及因地制宜等原则,并从管材选择、雨污管管径、沟槽回填、合理规划、科学施工及相关配套设施等方面提出某老城区雨污分流改造设计方案,以此解决雨污混乱、污水外溢问题,提升老城区品质和形象。Urban drainage system is an important part of urban public facilities and the"lifeline"to ensure urban operation.The drainage system in the old city has small trench specifications,few rain outlets and aging facilities,which leads to mixed flow of rain and sewage and affects the city image.Taking an old city as an example,this paper expounds the problem of rain and sewage confusion in the drainage system of an old city,puts forward that the transformation of rain and sewage diversion should follow the principles of sustainable development,combining with the present situation and adapting to local conditions,and puts forward the design scheme of rain and sewage diversion transformation in an old city from the aspects of pipe selection,rain and sewage pipe diameter,construction site layout,pipeline landfill and related supporting facilities,so as to solve the problem of rain and sewage confusion and sewage overflow,and improve the quality and image of the old city.
