摘要
Abstract
Taking a city in Northwest China as an example,the concentration of pollutants in inflow and outflow of three typical source LID facilities in rainwater garden,high-level flower beds and pervious paving in sponge city construction area of the city was measured and analyzed in combination with actual rainfall conditions of heavy rainfall,double-peak rainfall and small rainfall,multi-peak rainfall.The analysis showed that in the double-peak rainfall event of heavy rainfall,the concentration distribution of pollutants at the outlet of sponge city facilities was unimodal;in the event of low rainfall and multi-peak rainfall,the concentration of pollutants at the outlet of sponge city facilities was linear with negative slope.The pollutant removal rates of rain gardens and raised flower beds were higher in low rainfall events with multiple peaks than in heavy double peak rainfall events.The pollutant removal rate of permeable pavement in multi-peak rainfall events with low rainfall was lower than that in double-peak rainfall events with heavy rainfall.关键词
