Characterization of urban surface runoff in main districts of Kunming
摘要
Abstract
Located on upstream of Dianchi Lake,the pollution load of urban surface runoff in Kunming contributes greatly to the water quality of Dianchi Lake.In this study,runoff samples were collected from 12 monitoring sites in Kunming city during seven rain events in order to characterise urban surface runoff.The results showed that the average values for TSS,COD,TN and TP of urban surface runoff were 182.8 mg/L,138.2 mg/L,2.37 mg/L and 0.43 mg/L,respectively.There was significant difference in urban surface runoff among four functional areas.The pollution load followed the order of road areas ＞ commercial areas ＞residential areas ＞cultural and educational areas.During a single rainfall event,pollutant concentration was higher at beginning,and decreased quickly to a relative stable level.Land use function,rainfall characteristics,and traffic volume were the main factors determining urban surface runoff quality.The TSS was significantly correlated with COD,TN,and TP,indicating that most pollutants were absorbed on the particle surface.关键词
