- 摘要:
- 针对南昌市某片区污水处理厂进水污染物浓度低、进水水量变化大等问题，通过对污水管网系统现状和水量水质进行测算、监测和分析，对其存在的管网覆盖不全、工业废水纳管污染物浓度低、高校污水存在“潮汐性”、清污混流等进行系统诊断，并从前端污水全收集、中端污水传输转输全分流、末端污水处理能力满足需求等方面提出针对性的治理措施和系统性整治方案，同时对污水系统提质增效的效果和限制性因素进行预测。针对案例片区特有的工业废水、高校污水以及未建成区新建管网问题的分析与处理，对污水系统提质增效具有重要的参考意义，同时也可为我国南方城市其他类似片区的污水系统整治提供借鉴。
- Abstract:
- To address the challenges of low influent concentration and significant variations of influent volume at a sewage treatment plant in a district of Nanchang, this study measured, monitored, and analyzed the current situation and water quality and quantity of the sewage pipe network system. Key issues identified include incomplete coverage of the pipe network, low concentration of industrial sewage, intermittent sewage discharge from universities, and the mixing of clean water into the sewage system. Targeted treatment measures and systematic treatment plans were proposed, focusing on comprehensive sewage collection, transmission, distribution, and capacity enhancement to meet treatment demands. The effects and limiting factors of improving sewage system quality and efficiency were also assessed. In particular, analyzing and treating industrial wastewater, and university sewage and integrating new pipe networks in unbuilt areas offer important guidance for improving sewage quality and efficiency and serve as a reference for sewage system treatment in similar regions across southern China.
