| 摘 要： | 目的]研究合肥市校园区屋面和路面两类不同下垫面降雨径流污染特征。方法]以SS、CODCr、TN和TP作为主要水质指标进行比较,分析校园内屋面和路面2010年4场降雨径流污染物输出规律和降雨径流水质特征及其差异。结果]合肥市校园区降雨径流污染负荷水平较高,降雨径流主要污染物浓度一般在降雨初期较高,后期随着降雨历时的延长浓度下降,并趋于稳定;不同类型下垫面对降雨径流水质的影响差异较大,受人为活动直接干扰的路面降雨径流中SS和TP平均浓度远高于屋面,CODCr和TN平均浓度略高于屋面;合肥地区大气湿沉降对降雨径流中TN的贡献很大。结论]该研究可为合理开展城市径流面源污染控制和有效利用城区雨水资源提供科学依据。
