摘  要:初期雨水径流会对城市自然水体造成污染。为提供南昌市经开区初期雨水处理基础资料,本文对该地区初期雨水SS、浊度、COD_(Cr)、TN、NH_(3)-N、TP等水质指标进行了监测,分析了南昌市经开区主干道路上3种不同功能区初期雨水径流的污染特征。结果表明:初期雨水污染程度受不同用地类型的影响,商业区初期雨水的污染程度最严重,公路次之,住宅区污染程度最轻;不同降雨事件和功能区污染物浓度随降雨历时增加而逐渐升高,后逐渐降低趋于稳定,降雨强度越大冲刷效应越明显;SS是污染物质的重要载体,SS与浊度、COD_(Cr)、TP有较高的相关性。In order to provide the basic data of Rain Water treatment in the early stage of urban natural water body polluted by Rain Water runoff in Nanchang Economic Development Zone,the initial water quality indexes such as Rain Water SS,turbidity,COD_(Cr),TN,NH_(3)-N and TP were monitored,and the initial Rain Water runoff pollution characteristics of three different functional areas on the main road in Nanchang Economic Development Zone were analyzed.The results showed that in the early stage,the pollution degree of Rain Water was affected by different land use types,and the pollution of Rain Water was the most serious in the early commercial district,followed by road and residential area;the pollutant concentration in different rainfall events and functional areas gradually increased with the increase of rainfall duration,and then gradually decreased to stable,and the scouring effect became more obvious with the increase of rainfall intensity;SS is an important carrier of pollutants,and SS has a high correlation with turbidity,COD_(Cr)and TP.
