Change Law Research and Characteristic Analysis of Urban Pavement Runoff Pollution

Abstract:

Through the pavement runoff monitoring of USST（the University of Shanghai for Science and Technology） courtyard pavement runoff and JunGong road runoff, the analysis of main influence factors and pollution degree, this article indicate that underling surface, rainfall duration, rainfall intensity and rainfall are important influencing factors of initial runoff water quality. Organic and suspended solid are the main pollutants of urban runoff. COD, SS and turbidity are the main pollution index, and they present exponential change law and finally achieved stability along with the delay of rainfall. The more heavily it rains, the more quickly water quality become stabilization. Stable water quality are influenced by rainfall character and pavement character. The more heavily it rains, the better stable water quality is. The more dust pavement contain, the worse stable water quality is. Stable water quality of courtyard pavement runoff are better than street runoff.
