摘要:- 針對提質增效行動中污水管網排查體量大、投資費用高、耗時長等問題，分析了目前污水管網排查主要方法的優缺點，選取以水質對
比法為核心進行管網排查。南京市某污水收集系統排查項目，采用便攜式氨氮檢測儀對污水管網重要檢查井水質進行檢測分析，逐步縮小項目排查范圍后,再利用清疏檢測進行輔助排查，快速有效找到低濃度問題后做到即查即改，整改完成后再進行閉環水質檢測，驗證整改成效。結果表明，水質檢測是提質增效行動中的重要環節，在縮小排查范圍和確定問題點位中作用顯著；快速水質檢測手段（如便攜式氨氮儀）在污水管網排查項目中既經濟又快捷，具有推廣意義。
Abstract:- Aiming at the problems of large workload, high investment cost, and long time consumption in the quality and efficiency improvement action of drainage network investigation, the pros and cons of the main methods are analyzed, and the water quality comparison method is selected as the core for drainage network investigation. The portable ammonia nitrogen instrument was used to detect and analyze the water quality of key inspection wells in a drainage network of Nanjing and gradually narrow the project inspection scope before using the dredging test for auxiliary inspection. The low concentration problem was rectified right after found out quickly and effectively, and closed-loop water quality detection was conducted after the rectification is completed to verify the effectiveness. The results show that water quality testing is an important link in the action of quality and efficiency improvement, and plays a significant role in narrowing the scope of investigation and determining the location of the problem. Rapid water quality detection methods (such as portable ammonia nitrogen instruments) are economical and quick in drainage network investigation projects, and have promotion significance.
