摘要
随着城市点源污染控制程度的提高,雨水径流引起的面源污染日益突出。非渗透性地表径流污染成为城市水体污染的主要来源。对上海市城区非渗透性地表径流进行了为期3年的采样调查,监测了COD、BOD5、SS、NH3-N、TP和TN等污染物指标,并估算了单位面积径流年污染负荷。结合上海市实际情况,提出了城区径流污染控制的综合策略。
With effective control of point source pollution in Shanghai, runoffs from urban impervious surfaces are now major sources of water pollution in the region. This paper presents characteristics of urban runoffs in Shang hai based on the results of a three-year field study. Environmental quality parameters （COD, BOD5, SS, NH3-N, TP and TN） for 492 samples taken at 19 sampling points following 22 rainfall events in 2003-2005, were measured and data analyzed; the pollution loadings of urban runoffs were estimated. Recommendations for better management and control of urban runoff pollution in Shanghai are proposed.
