南京城区两类典型屋面降雨径流的特征
Characteristics of Two Types of Typical Roof Rainfall Runoff in Urban Areas of Nanjing
摘要
Abstract
Taking 2 rainfalls of Nanjing in 2014 as an example,the author analyzed the roof runoff water quality. Characteristics of runoff in different roof,first flush of roof runoff and correlations between pollutants of roof runoff were studied in the paper. The results show that the pollution extent of COD is serious. Coefficient of dispersion of water quality index show that SS > COD > NH3 N > pH, and SS,COD,NH 3 N are basically the same trend with the rainfall duration. Besides,pollution load of COD and NH 3 N which in flat cement roof are higher than in the top tile roof,but the pollution load of SS is lower than which in the top tile roof . First flush effect of the slope tile roof runoff is obvious,but there is no first flush effect in the flat cement roof runoff. SS and COD have a good correlation,but correlations between NH 3 N and SS,COD are poor.关键词
