Research on the Characteristics of Rain Water Runoff Pollution in the Early Stage of Different Functional Areas in Nanchang Economic Development Zone
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,CODCr,TN,NH3-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,CODCr and TP.
