- 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.
