摘要
为研究合流制城区的暴雨径流污染特征,在武汉市汉阳区的 4个合流制集水区布置了监测断面,对暴雨径流过程中的水质、水量进行了连续监测。结果表明:污染物浓度的峰值一般提前或同步于径流量的峰值,初期径流污染较重;采用污染物浓度变异指数可以反映不同集水区暴雨径流污染的差异性;汉阳城区暴雨径流的SS、COD、TP和TN平均浓度分别为 601. 1、299. 2、0. 88和 12. 26mg/L,同珠海市相比,其暴雨径流污染水平明显要高。
In order to investigate the characteristics of urban storm runoff pollution of combined sewer system, monitoring sections were arranged in four catchment areas to make continuous monitoring on quality and quantity of storm runoff during heavy rain period. The result shows that the peak of pollutant concentration is ahead of or synchronous with that of runoff, and heavy pollution occurs in initial period of storm runoff. Index of variation in pollutant concentration can be used to exhibit the disparity of storm runoff pollution in different catchment areas. The mean concentration of SS, COD, TP, and TN of storm runoff in Hanyang District is 601.1, 299.2, 0.88, and 12.26 mg/L respectively, the storm runoff pollution level is significantly heavier as compared with that in Zhuhai City.
