摘要:
通过对苏州市古城区内商业区、现代住宅区、老旧住宅区、交通区、园林旅游区这5种具有代表性的功能区路面降雨径流中SS、COD、TN、NH3+-N、TP水质指标的分析,探讨了不同功能区降雨径流中污染物浓度差别,不同污染物之间的相关性关系和初期冲刷效应。结果表明,路面降雨径流中污染物浓度存在空间分布差异,商业区和交通区路面径流污染最为严重,其中交通区SS的EEMC值超出污水综合排放二级标准16.79倍,COD的EEMC值超出地表水环境质量V类标准6.88倍; 降雨径流中SS与TP、TN、COD之间存在良好的相关性,交通区路面降雨径流中各污染物之间呈现极显著性相关; 不同功能区路面降雨径流中污染物大多存在初期冲刷现象,交通区与园林旅游区出现初期冲刷频率高,商业区和老旧住宅区初期冲刷强度大,相比其他污染物,SS最易出现初期冲刷现象,降雨特征参数对初期冲刷效应有一定影响。
Abstract:
The differences of pollutant concentration, the correlation between different pollutants and the first flush effect in rainfall runoff of different functional areas were discussed, through analysis the water quality indexes such as SS, COD, TN, NH3-N and TP in the five representative functional areas, including commercial areas, modern residential district, old residential district, transportation area and landscape tourist areas in Suzhou Ancient City. The results showed that there was a spatial distribution difference of concentration of pollutants in runoff, and the pollution in commercial and traffic area were more serious than other areas. There was a good correlation between SS and TP, TN and COD in rainfall runoff, and there was a very significant correlation between the pollutants in the runoff of transportation area. During the rain flush, most pollutants had first flush effect. The traffic area and the landscape tourist area had high first flush frequency, and the first flush intensity of commercial areas and old residential areas was large. Compared with other pollutants, SS was most prone to initial scouring. The rainfall characteristic parameters had a certain influence on the first flush effect.
