摘要
选取苏州高架路面、沥青油毡屋面、瓦屋面3种城区典型性汇水面的雨水径流作为研究对象,对径流中主要污染物COD,SS,TP,NH3-N进行监测,对不同汇水面的初期冲刷规律作曲线拟合和对比分析,研究得出影响初期冲刷效应的主要因素是降雨强度。
Three typical gathering grounds of the urban rainwater runoff were selected, which were the elevated road, asphalt roof and tile roof of Suzhou. COD, SS, TP and NH3-N as the main pollutants in the runoff were monitored, and curve fitting and comparative analysis were discussed for the flush rules in initial stage of different catchment area. The result shows that the main factor which affects the flush rules in initial stage is the rainfall intensity.
