- Abstract:
- In response to local needs, Jiangsu Province has divided the urban built?up area into several zones to assess sewage treatment quality and efficiency, and then created an action plan to address the findings. The “333” Action Plan for Improving the Quality and Efficiency of Sewage Treatment in Jiangsu Province was issued, detailing the guiding principles of “three elimination” as the basis, “three remediation” as the focus, and “three improvement” as the goal. This framework is designed to ensure effective sewage collection, removal of external water intrusion, and a gradual improvement in sewage treatment quality and efficiency. Combined with the practice of improving the quality and efficiency of urban sewage treatment in Jiangsu Province in recent three years, this paper analyzes the policy documents and technical measures. The experience of Jiangsu was summarized in four aspects: “block division, gradual promotion”,“system investigation, find out the resources”,“identifying and filling in gaps, eliminating blank areas of pipe network”,“mixed and wrong connection transformation, rainwater and sewage diversion”. And the application effect of Jiangsu’s experience in the service scope of Nanjiao sewage treatment plant of Taicang was introduced, providing a reference technical roadmap for the improvement of sewage quality and efficiency in other cities.
