An Ezperimental Study on Green Water-storing Roofs Removal Efficiency of Pollutants in Rainwater Runoff

摘要：

This article makes an experimental study on the quality of common roof rainwater and the rainwater treated by the green water-storing roof. The findings are as follows: the urban green water-storing roof has a high removal efficiency of SS, COD, TN and TP in roof rainwater runoff. To be specific, the removal rate of SS can be up to 80% to 90%; COD, 50% to 70%; TN, 50% to 70%.TP, 40% to 70%. After the pollutants are removed by the green water-storing roof, the roof rainwater can meet the quality standard of Urban Wastewater Reuse: Urban Miscellaneous Water Quality(GB/T 18920-2002).
