Design of pollution control system for CSOs of Huangxiao River in Wuhan

黄孝河位于湖北省武汉市汉口中心片区,历史悠久,承载着武汉市的沧桑巨变,伴随城市的发展,水环境逐步恶化,目前已然成为影响城市形象的黑臭水体,合流制排水系统污水在雨季发生的溢流(CSOs)是主要因素。工程通过对黄孝河CSOs污水截流、调蓄、处理等有效治理措施,将污染物削减后再行排放,年溢流频次控制在10次以内,可有效缓解C SOs污染。

Huangxiao River is l ocated in the central area of Hankou,Wuhan,Hubei province,with a long history.Carrying the vicissitudes of Wuhan,wit h the development of this cit y,the water environment is deterior ating.At present,it has becom e a black and odorous water influencing the image of the city.The overflow(CSOs)of sew age in the combined drainage system during the rainy season is th e main factor.By intercepting the CSOs sewage of Huangxiao River,and by storing,treating and o ther effective treatment meas ures,cut down the pollutant b efore discharge,annual overflow frequency sho uld be controlled within 10ti mes,CSOs pollution can be eff ectively alleviate.
