| 摘 要： | 以重庆大渡口区建胜镇为典型区域,选取水泥瓦屋顶、石棉瓦屋顶、水泥平屋顶、居民区水泥路面、餐饮沥青路面、油库沥青路面等不透水下垫面和附近一条合流制溢流渠为采样点,研究了城镇地表径流中营养性污染物和重金属排放特征.结果表明,路面径流中TSS、COD、TN、TP平均质量浓度为(1 681.2±677.2)、(1 154.7±415.5)、(12.07±2.72)、(3.32±1.15)mg·L-1,普遍高于屋面径流污染物平均质量浓度:(13.3±6.5)、(100.4±24.8)、(3.58±0.70)、(0.10±0.02)mg·L-1.不透水地表径流中,TDN、TDP分别占TN、TP的62.60%±34.38%、42.22%±33.94%.与中心城区相比,本城镇地表径流污染物质量浓度一般较高.合流制溢流中,TSS、COD、TDN、TN、TDP、TP为(281.57±308.38)、(231.21±42.95)、(8.16±2.78)、(10.60±3.94)、(0.38±0.23)、(1.51±0.75)mg·L-1,重金属质量浓度均未超过地表水环境质量Ⅴ类标准.合流制溢流中大部分污染物存在初期冲刷效应,而TSS的初期冲刷效应较弱.合流制溢流中,COD、TP与TSS都具有显著正相关关系,NH+4-N和TP、TDP、TN、TDP之间呈显著正相关关系,而NO-3-N和其它指标都呈负相关关系.
