摘要
城市污水管网是城市的重要组成部分。国内大多数城镇的污水管网已投产运行数年,管道漏损、路面塌陷、污水外溢、污染河道等现象屡屡发生,存在较大的环保风险和安全隐患。近些年,国家住房和城乡建设部、生态环境部、发展改革委等发布了多份与城镇污水管网改造相关的政策文件,污水管网修复在全国范围内开展起来。文中通过对某镇区现状管网的摸排调研,制定优化改造方案,并对建设及运行过程中遇到的问题及经验进行归纳、总结和提炼,旨在为国内类似污水管网的优化改造工程提供基础经验和借鉴。
The urban wastewater pipe network is an important part of the city.The wastewater pipe network in most cities and towns at home has been put into operation for several years.Pipeline leakage,road collapse,wastewater overflow,and river pollution have occurred frequently,posing great environmental risks and potential safety hazards.In recent years,the Ministry of Housing and Urban-Rural Development,the Ministry of Ecology and Environment,and the National Development and Reform Commission have issued a number of policy documents related to the renovation of urban wastewater pipe networks,and the restoration of wastewater pipe networks has been carried out nationwide.Through the investigation and investigation of the current pipeline network,the optimization plan is formulated,and the problems and experiences encountered in the construction and operation process are refined and summarized,aiming to provide an experience basis and reference for the optimization and transformation project of the domestic wastewater pipeline network.
