| 摘 要： | 城市道路地表径流污染已经成为城市水体恶化的重要原因之一。2006年8月-11月,通过对成都市9条不同类型道路6次降雨径流水质的监测分析,探讨了成都市路面径流污染的现状、成都市道路地表径流的污染负荷及道路地表径流中污染物之间的相关性关系。结果表明,成都市道路地表径流中污染物SS、COD、TN、TP的含量高,浓度均超出地表水环境质量Ⅴ级标准。成都市道路地表径流的年污染负荷为LCOD=3.1×104t,LTN=1.19×104t,LTP=1174.9 t,LZn=109.46 t。SS浓度与污染物COD、TN、TP、Zn浓度之间存在较好的相关关系(R2>0.8)。可以通过控制径流系数、削减径流中的污染物含量和污染物总量控制3个方面的措施来进行道路地表径流污染的削减。

| Abstract: | Urban-road runoff has become one of the most important reasons causing the deterioration of the urban water quality.Six rainfall-runoff water qualities from nine different kinds of roads were monitored in Chengdu.The actuality of surface runoff,the pollution loading of Chengdu Urban-road runoff were investigated and the correlations were analyzed between COD,TN,TP,Zn concentration and SS content.The results showed that the concentrations of SS,COD,TN and TP all exceeded the fifth level of the environmental ... |
