高效组合澄清系统在某雨水泵站污染物削减中的应用

Analysis on Reduction of Pollutant from Rainwater Pumping Station by High-Efficiency Comagnetic-Flo System

随着国家对环境要求逐步提高,城市河道水体黑臭现象已引起人们的广泛关注,而城区雨水泵站放江造成的污染是制约河道治理的难点问题,需采取有效措施对泵站污染物在排河之前进行处理。文中分析了高效组合澄清系统对上海市中心城区某雨水泵站前池污染物的削减效果,观测了受纳河道污染的减轻情况。结果表明,高效组合澄清系统对SS的去除率为80%~87%,对COD的去除率为50%~80%,对TP去除率为60%~86%。说明高效组合澄清系统对去除颗粒态污染物,提高水体透明度,降低泵站水体COD.TP效果较好,适用于雨水泵站前池污染物的削减。

With the gradual improvement of national environmental requirements,the phenomenon of black and odorous water bodies in urban river bodies has aroused widespread concern,and the pollution caused by the discharge of rainwater pumping stations in urban areas is a difficult problem that restricts the regulation of river courses.It is necessary to take efiective measures to deal with the pollutants from the pumping station before discharging into the river.In the paper,effect of high efficiency combined clarification system on reducing pollutants in the forebay of a rainwater pumping station in the central city of Shanghai is analyzed.The results show that removal rates of SS,COD and TP were 80%~87%,50%~80%and 60%~86%,respectively.High-efficiency combined clarification system is effective in removing particulate pollutants,improving water transparency and reducing COD and TP in the pumping station,and it's suitable for reducing pollutants in the forebay of rainwater pumping station.
