摘要
合流制溢流污染是造成汛期河道水质下降的重要影响因素之一。文章对北京市中心城区试点区域通过截流改造方式控制合流制溢流污染实施方案进行了介绍,对流域范围内污染物消减效果进行分析。结果表明,因地制宜通过截流改造方式控制合流制溢流污染具有操作简单特点,可以有效减低入河污染物浓度,其中,COD、BOD5、SS、NH3-N、TP、TN和石油类平均消减比例分别为61.6%、57.8%、57.6%、42.4%、49.5%、48.9%和53.3%。该研究可以为其他类似地区合理确定合流制溢流污染治理方式提供借鉴。
Combined Sewer System Overflow(CSO)pollution is one of the important factors affecting the deterioration of water quality in flood season.This study introduces the scheme of controlling CSO pollution in typical urban areas of Beijing by means of river closure and reconstruction,and analyzes the effect of pollution reduction.The results show that it is easy to reduce the pollutants entering the river by controlling the combined flow and overflow pollution by means of interception and transformation.The average reduction rates of COD,BOD5,SS,NH3-N,TP,TN and petroleum were 61.6%,57.8%,57.6%,42.4%,49.5%,48.9%and 53.3%,respectively.The results of this study could provide a case basis for other similar areas to control CSO pollution.
