事实证明透水型路面砖及铺设系统(在本文中,所指透水路面砖可相互替换)能够有效地“捕集”和降解雨水中所含的城市污染物,例如:碳氢化合物和金属元素。英国的Formpave公司和Coventry大学经过5年试验证明:加在试验所用溶液的中矿物油,98.7%能被滞留在路面铺设材料的结构中;被滞留的油污经多样性的生物降解作用,六个月的降解量约为滞留量的45%。这种路面铺设系统成功的关键是:铺设于基层下面的土工织物薄膜。这种土工织物的物理和化学性能可降低水的流动速度,使污染物停止流动,为降解油污的微生物生长提供了适宜的环境。透水型路面砖已在世界各地广泛应用,在英国,它正在为从源头控制污染物和推动建立可持续发展的生态环保城市道路排水体系,做出重大贡献。
Translucent paving blocks and laying systems (in this paper, the interpenetration of permeable pavers) have proven to be effective at “trapping” and decontaminating urban pollutants contained in rainwater, such as hydrocarbons and metallic elements. Formpave and Coventry University in the United Kingdom after 5 years of testing proved that: 98.7% of the mineral oil added to the solution used in the test can be retained in the structure of the road paving material; the retained oil is subjected to various biodegradation and six The monthly degradation is about 45% of the retention. The key to the success of this paving system is the geotextile film laid under the grassroots. The physical and chemical properties of such geotextiles reduce the flow of water and stop the flow of contaminants, providing a suitable environment for the growth of microorganisms that degrade oil. Permeable pavers are widely used all over the world and in the United Kingdom, they are making a significant contribution to controlling pollutants at source and promoting the development of sustainable eco-friendly urban road drainage systems.
