摘要

Campus, sidewalk, business-street and viaduct's surface runoff in Beijing city were selected to carry on the sampling and examination, through several field rainfall contrastively analysis found that: COD, SS and the TP of the viaduct initial period runoff is obviously higher than other functional districts, and the TN of the campus is highest. Although the runoff water quality is difference in different functional districts, the concentration first flush phenomenon is all very obvious. Various functional districts have the obvious mass first flush phenomenon. When we control 20％ of the initial stormwater runoff, it is possible to control 40％-60％ of the pollutant total quantity.
