旧城区排水管网雨污分流改造设计与思考

市政排水系统对于城市建设起着举足轻重的作用,尤其是在城市化不断推进的背景下,其作用愈发凸显。市政排水系统作为其他各项工程的基础设施或者配套项目,其质量直接影响着城市的整体功能。为了从源头上治愈水污染顽疾,积极推进控源截污,切实推进流域水环境综合治理,需要对市政排水系统进行正本清源地改造,分析其污染原因,弄清楚污染源。针对旧城区地下管线错综复杂、现状改造条件受限、协调工作量特别大等特点,结合既有排水系统、改造区地形地貌等因素综合分析,提出了设计的总体思路,因地制宜制定雨污分流管网改造方案,以期达到雨污分流、提高环境效益的目标。

Municipal drainage systems play a pivotal role in urban construction,especially in the context of continuous urbanization.As the infrastructure or supporting project of other projects,the quality of municipal drainage system directly affects the overall function of the city.In order to cure the stubborn disease of water pollution from the source,actively promote source control and interception,and effectively promote the comprehensive treatment of the water environment in the basin,it need to carry out the transformation of the municipal drainage system to clean up the source,analyze its causes,and figure out the source of pollution.In view of the intricate underground pipelines in the old urban area,the limited conditions of the current transformation,and the particularly large coordination workload,combined with the comprehensive analysis of the existing drainage system,the topography and landform of the reconstruction area,this paper puts forward the general idea of the design,adapts measures to local conditions,and formulates a renovation plan for the rain and sewage diversion pipe network,in order to achieve the goal of rain and sewage diversion and improve environmental benefits.
