    摘要:

    为改善透水铺装在弱透水土质地区的应用,通过增加渗透导管的方式改良了常规透水铺装的土基层。通过人工降雨试验对改良型透水铺装及其不同结构层对弱透水土质地区典型雨水径流中COD、TN、TP和Cu2+等污染物的去除效果进行了分析,并与相同条件下的常规透水铺装进行了对比。结果表明,改良型透水铺装对4种污染物的去除效果有明显增强,在60min降雨历时条件下,降雨重现期为2 a时改良型透水铺装对4种污染物的去除能力分别提升了11.87%、27.61%、9.17%和29.02%,且降雨重现期越短越有利于透水铺装对COD、TN、TP和Cu2+的去除。

    Abstract:

    In order to improve the application effects of permeable pavement in weakly permeable soil areas, the conventional permeable pavement soil base layer has been improved by increasing the permeation tube. The removal efficiency of COD, TN, TP, Cu2+ and other pollutants from typical rainwater runoff in weak permeable soil area by improved permeable pavement and its different structural layers were analyzed through artificial rainfall test, and it is compared with conventional pervious paving device under the same conditions. The results show that the removal effect of improved permeable pavement on four pollutants is obviously enhanced. Under the condition of 60 min rainfall duration, the removal capacity of improved permeable pavement for four pollutants increased by 11.87%, 27.61%, 9.17% and 29.02%, respectively, when rainfall recurrence period was 2 years. The shorter the recurrence period of rainfall, the better removal effects of COD, TN, TP and Cu2+ by permeable pavement.
