摘要
选取武汉市动物园4种典型的不透水面暴雨径流污染特征进行了系统的研究,以期为旅游区面源污染危害评价和治理提供基本的依据。结果表明,动物园4种不透水面初期径流污染物浓度很高,COD最大值达1140 mg/L,下垫面类型及地表累积污染物是影响径流水质的主要因素。通过无量纲累积曲线的分析,表明旅游区不透水面径流初期冲刷严重,该曲线还为面源治理提供了重要的工程参数。
In order to provide basic information for effective assess and control of diffuse pollution in tourist attractions, stormwater runoff from four impervious surfaces were selected for study in Wuhan Zoo, Wuhan city, China. The result showed that main pollutants （ TN, TP, COD, SS ） concentrations of surface runoff were much higher in initial stages,especially the maximum value of COD got to 1140mg/L. The types of ground surface and pollutants stored on those surfaces were key factors for effecting on stormwater runoff pollution. The first flush phenomenon was significant by analyzing on dimensionless cumulative curve. At the same time, the curve provided important engineering parameters for runoff treatment.
