- Abstract:
- In order to improve water quality of middle ancient canal in Zhenjiang city, a pollution control project was carried out. The research area is the middle catchment area of the ancient canal river system in the old town of Zhenjiang. The specific research object is the runoff of the outfall of rainwater-sewage confluence in the area. On the basis of detecting and analyzing the water yield and water quality of the runoff of rainwater-sewage confluence, a combined technology which contains four independent continuous processes for lowering pollution load was developed, and system equipment was established and put into operation. The processing effects of the project were monitored and analyzed. The results show that the pollution control project of outfall runoff is efficient, which decreases the pollution load including chemical oxygen demand(COD), total phosphorus(TP), suspended solids(SS), and ammonia-nitrogen(NH3-N). As a result, the water environment of the ancient canal is protected.
- 为改善镇江市古运河中段水质, 实施了相应污染控制工程, 选择镇江市老城区古运河水系为研究区域, 以古运河中段汇水区雨污合流排口的径流为研究对象.在分析该区域晴天和雨天雨污合流排口水量、水质的基础上, 针对该区域的径流特点, 确定了降低污染负荷的组合处理工艺, 该组合处理工艺由4个连续的独立处理工艺流程组成.然后根据所确定处理工艺开发了系统成套设备并投入运行.对工程处理效果进行了监测和分析, 结果表明, 此雨污合流排口污染控制工程可行, 并有效降低了排入古运河的降雨径流的各项污染指标, 包括化学需氧量(COD)、总磷(TP)、悬浮物含量(SS)、氨氮(NH3-N), 从而有效保护了古运河的水环境.
