Abstract

Simultaneous monitoring of the water quality in the outlet of storm sewer and downstream receiving water was performed in two small watersheds with typical underlying surfaces in Beijing urban and suburban during four rainfall events of 2008—2009.The pollution of runoff in urban storm sewer was severe,with its SS concentration higher than urban sewage.Its COD,NH3-N,TN and TP were lower than urban sewage,but higher than Grade Ⅴ water of GB3838—2002 and Grade B of GB18918—2002.Runoff EMC of Muxiyuan small watershed was 21.4%—246.5% higher than Xipu,due to lower green land coverage,larger road to land area ratio and worse suburban environmental management of Muxiyuan.The pollution concentration in urban storm sewer reflects a First Flush Effect.COD and TP were strongly related to SS in rainfall runoff.The pollution concentration in receiving water increased by 16.9%—541.7%,with the highest extent for SS,COD and NH3-N.The urban green land can reduce SS and the transported organic materials in rainfall runoff.
