Investigation and Characteristics Analysis of Runoff Water Quality on Vehicular Roads in Beijing Urban Area
摘要
Abstract
Motor way runoff pollution is an important part of the urban non-point source pollution. On basis of investigation of urban motorway runoff in Beijing, runoff quality and characteristics were analyzed and summarized. The results show that the average concentration of the conventional pollutants in road runoff is beyond level V of the Surface Water Environment Quality Standard (GB 3838-2002), and all pollutants show good correlation with SS. Moreover, biodegradability of runoff is not obvious and precipitability is good; rainfall characteristics, traffic flow, land use types and environmental features around the road influence the runoff quality; concentration of first flush is significant, but pollution of load first flush is not significant, which happens more easily for freely soluble pollutant. The research results can provide reference for pollution control technology implementation and resource utilization of the urban road runoff.关键词
