| 摘 要： | 选取广州市中心城区典型纯雨水排水口进行了18场降雨的径流污染监测,分析了在典型小雨、典型中雨及典型大雨场次下排水口各水质指标随降雨历时的变化规律。研究结果表明,雨水口的COD浓度峰值一般不超过55 mg/L,均值通常介于20~30 mg/L雨水口水质随降雨过程的变化规律较为复杂,初始冲刷效应最明显的水质指标是SS,其次是COD,NH3-N和TN基本没有初始冲刷效应。

| Abstract: | Taking a typical outfall solely draining away rainfalls as trial point, the monitoring data of 18 runoff pollution have been recorded. The water quality index with the changing law of the rainfall have been analyzed in typical drain under light rain, moderate rain, and heavy rain events respectively. The results show that the maximum of COD concentration is generally not more than 55mg/L, and the mean value is usually between 20 mg/L~30mg.The variation law of the water quality of the rain water outlet with the rainfall is complex,the most obvious quality indexes of the first flush effect is SS, followed by COD, NH3-N and TN had no initial scouring effect. |
