上海某乡镇农村生活污水收集处理研究

通过对上海市崇明区某乡镇农村污水收集处理系统现状的调研,进一步分析现场所发现的诸多问题,因地制宜,探索基于世界级生态岛建设农村污水处理高标准下的生活污水收集处理提标改造工程的新工艺、新技术,并针对原污水处理工程的设计问题提出对策建议及整改措施,以便推广利用。

Calculation of Intercepted Volume of Sewer Overflows: a Model for Control of Nonpoint Pollution Sources in Urban Areas

The authors discovered large differences in the characteristics of overflows by the calculation of 1） intercepting volume of overflows for sewer systems using SWMM model which takes into consideration the runoff and pollutants from rainfalls and 2） the intercepted volume in the total flow at an investigation site. The intercepting rate at the investigation point of CSOs showed higher values than the SSDs. Based on the modeling of the receiving water quality after calculating the intercepting amount of overflows by considering the characteristics of outflows for a proper management of the overflow of sewer systems with rainfalls, it is clear that the BOD decreased by 82.9%-94.0% for the discharge after intercepting a specific amount of flows compared to the discharge from unprocessed overflows.

北京市农村生活污水收集处理研究与思考

以当前北京市正在开展的农村污水治理为背景,结合现行标准规范及支持政策,综合美丽乡村建设的生活污水治理思路,就农村生活污水收集处理的现状及基本情况进行阐述。通过对截污模式选择、化粪池改造、建设和运维管理等农村生活污水收集处理工程实施中突出问题的研究与思考,总结"通州模式"经验,提出下一阶段工程实施的方向及重点,对于工程实践具有一定的指导意义。
