- 摘要:
- 《城镇污水处理提质增效三年行动方案（2019—2021年）》提出加快补齐城镇污水收集和处理设施短板，通过推进生活污水收集处理设施改造和建设，实施管网混错接改造、管网更新、破损修复改造等工程，实现清污分流、雨污分流、查漏补缺等目标，全面提升现有排水设施收集效能。结合镇江提质增效达标区“四位一体”排水管网诊断项目经验，总结归纳了提质增效达标区管网测绘、检测、排查一系列诊断工作与整改和修复设计的配合流程，可为其他城市开展污水处理提质增效排水管道“四位一体”项目提供参考。
- Abstract:
- The Three-year Action Plan for Improving the Quality and Efficiency of Urban Sewage Treatment (2019-2021) proposes to speed up the completion of the short board of urban sewage collection and treatment facilities. Projects such as the transformation of mixed and wrong connection of pipe networks, the renewal of pipe networks, and the repair and reconstruction of damaged pipes can be implemented by promoting the transformation and construction of domestic sewage collection and treatment facilities. Thereby the goals of separating clean water and sewage, separating rainwater and sewage, and detecting leakage and making up for defects can be achieved and comprehensively improve the collection efficiency of existing drainage facilities. Taking the experience of “four-in-one” drainage network diagnosis project in quality and efficiency improvement standard area in Zhenjiang, the matching process of diagnosis work and repair design in pipe network mapping, detection, investigation were summarized. The paper aims to provide a reference for other cities to carry out the “four-in-one” project of quality and efficiency improvement of drainage pipeline for sewage treatment.
