城镇污水处理提质增效推进的江苏经验
- Title:
- Thinking and Practice of Improving Quality and Efficiency of Sewage Treatment in Jiangsu Province
- Keywords:
- municipal sewage; Jiangsu Province; quality and efficiency improvement; mixing of rainwater and wastewater; diversion of rainwater and wastewater
- 摘要:
- 江苏省结合地方实际，将全省县、市建成区划分为若干污水处理提质增效达标区，化整为零，并印发《江苏省污水处理提质增效精准攻坚“333”行动方案》，明确了以“三消除”为基础、“三整治”为重点、“三提升”为目标的工作思路，收齐污水、赶尽外水，逐步实现污水处理提质增效。结合江苏省近3年在污水处理提质增效工作方面的具体实践，从政策文件、技术措施等方面进行了分析，总结得出“区块划分，逐步推进” “系统排查，摸清家底”“查缺补漏，消除管网空白区”“混错接改造，源头分流”四方面的江苏经验。并介绍了江苏经验在太仓南郊污水处理厂片区的应用效果，为其他城市污水提质增效工作提供了可借鉴的技术路线。
- 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.
