雨污分流工程后期运维管理短板及长效管理对策

Shortcomings in Post-construction Operation and Maintenance of Separate Sewer Systems and Long-term Management Strategies

摘要:

伴随城市水环境综合治理与黑臭水体整治工作的持续推进,国内各地大规模实施雨污分流改造,有效解决了污水直排与溢流污染问题。然而,行业内长期存在重建设、轻运维的倾向,管网混接、淤堵、权责不清、资金不足、监管缺位等问题,治理成效难以持久巩固。文章从管理、资金、技术、公众参与四个维度剖析运维痛点,并从权责划分、资金保障、智慧运维、源头管控、考核机制、宣传引导等方面构建长效管理体系,结合实例数据进行验证,为雨污分流工程的常态化、精细化运维提供有益借鉴。

Abstract:

With the continuous promotion of comprehensive management of urban water environment and the remediation of black and odorous water bodies, large-scale rainwater and sewage diversion transformation has been implemented in various parts of China, effectively alleviating the problems of direct discharge and overflow pollution of sewage. However, there has been a long-term tendency in the industry to prioritize construction over operation and maintenance, with increasingly prominent problems such as mixed connections, blockages, unclear rights and responsibilities, insufficient funds, and lack of supervision in the pipeline network. The effectiveness of governance is difficult to consolidate in the long run. The article analyzes the pain points of operation and maintenance from four dimensions: management, funding, technology, and public participation. It constructs a long-term management system from the aspects of power and responsibility division, funding guarantee, intelligent operation and maintenance, source control, assessment mechanism, and publicity guidance. It is verified with case data to provide useful reference for the normalization and refinement of operation and maintenance of rainwater and sewage separation projects.
