摘要
以路面滞留雨水作为研究对象,对石英砂进行分组控制变量试验,分析使用不同粒径的过滤材料对过滤速度以及过滤效果的影响,找出相对过滤速度与相对过滤效率最大的粒径级配,通过进行相对普通路段更多的污水量试验,对易积水路段的实际情况进行拟合,试验表明在相对更多的污水量下由于水压影响将使过滤系统的相对过滤时间更少,相对过滤效率更高,提高了该装置在易积水路段使用的可行性。
Taking the road surface rainwater as the research object.The quartz sand was tested by group control variable.The influence of different particle size filter materials on the filtration rate and filtration effect was analyzed.The particle size gradation with the largest relative filtration velocity and relative filtration efficiency was found out.The test results show that the relative filtration time of the filtration system will be less and the relative filtration efficiency will be higher due to the influence of water pressure under relatively more sewage volume,which improves the feasibility of using the device in the section prone to ponding.
