砖下垫面对降雨径流污染物削减作用的研究

Research on Reduction Effects of Brick Substrate on the Runoff Contaminants

针对目前主要的房屋材料──砖,进行了一系列室内模拟降雨径流实验,考察了不同污染物浓度、不同流量对实验结果的影响。结果表明:原水浓度越小,砖吸附径流污染物的效果越好;降雨强度越大,径流污染物削减率越好。

A series indoor runoff simulating experiments have been carried out on brick which is the main housing material presently,to test the effects of different concentrations and different flow rates.The results show that the absorption of runoff pollutant increases with the concentration of the crude water while the reduction of runoff pollutant decreases with the rainfall.
