Permeable pavement for intensively removing nitrogen pollutants in rainwater runoff
The invention particularly relates to a permeable pavement for intensively removing nitrogen pollutants in rainwater runoff, the permeable pavement comprises a surface layer, a leveling layer, a base layer and a cushion layer from top to bottom, an internal water storage area and a bark chip layer are arranged at the bottom of the cushion layer, the internal water storage area forms an anoxic environment at the bottom of the permeable pavement, enough carbon sources are provided with the bark scraps, so that denitrification is promoted, and removal of nitrogen pollutants in rainwater runoff is enhanced. Aiming at the defects of the traditional permeable pavement in the prior art, on the basis of the permeable pavement technology, the removal effect of the permeable pavement on nitrogen pollutants in rainwater is improved by strengthening the denitrification effect in the permeable pavement. The permeable pavement is low in cost, convenient to maintain and manage and suitable for large-scale popularization and application.
本发明具体涉及一种强化去除雨水径流中氮类污染物的透水铺装，自上而下的结构分别是：自上而下的结构为面层、找平层、基层与垫层，所述垫层底部设置的内部蓄水区与树皮屑层，所述的内部蓄水区在透水铺装底部形成缺氧环境，与所述的树皮屑提供足够的碳源，以促进反硝化，强化雨水径流中氮类污染物的去除。本发明针对现有技术中传统透水铺装存在的不足之处，以透水铺装技术为基础，通过强化透水铺装中的反硝化作用，提高透水铺装对雨水中氮类污染物的去除效果。本透水铺装造价低，维护管理方便，适合大规模推广应用。
