| 中文摘要: |
| 通过采集杭州市临安区不同功能区6个监测点3 次降雨径流过程的水样，监测降雨径流中总磷（TP）、总氮（TN）、氨氮（NH3-N）、化学需氧量（COD）的EMC值，分析城市道路地表径流污染特征。结果表明，临安区不同功能区路面降雨径流中相同污染物浓度不同，降雨径流污染物EMC平均值由高到低为商业区＞交通区＞居民区＞文教区。降雨径流污染物EMC值随着降雨时间增加逐渐降低。降雨前期空气污染越严重，降雨径流污染物浓度越高，即冬季降雨径流污染物浓度大体上高于秋季。 |
| 英文摘要: |
| In this paper， 3 rainfall runoff samples were collected from 6 sites in different functional zones of Linan， Hangzhou， the EMC values of total phosphorus（TP）， total nitrogen（TN）， ammonia nitrogen（NH3-N）， chemical oxygen demand（COD） in the samples were monitored and the pollution characteristics of the road rainfall runoff were analyzed. The results showed that the concentration of the same pollutant varied in different functional zones. The average EMC values from high to low were business district， traffic area， residential district， institutes and colleges district. The pollutant EMC values in rainfall runoff decreased as the rainfall time increased. The more serious of air pollution before rain， the higher concentration of the pollutant in rainfall runoff. In general， the pollutant concentration was higher in winter than that in the fall. |
