Structure of biological decontamination retention facilities in rainy area
The invention provides a structure of biological decontamination retention facilities in a rainy area. The structure comprises a planting soil layer, a retention layer and drainage layers, wherein theplanting soil layer is covered with vegetation, the vegetation and the planting soil layer form first filtration, the retention layer comprises an artificial filler layer and a submerged area, the artificial filler layer forms second filtration, the submerged area forms third filtration, and the rainwater sequentially passes the first filtration, the second filtration and the third filtration andthen leaves from the drainage layers. According to the structure, compared with the prior art, the submerged area is additionally arranged in the retention layer, so that the effect of removing nitrate nitrogen is improved.
本发明提供了一种多雨地区生物去污滞留设施结构，包括值土层、滞留层和排水层，值土层上设置有植被，植被和值土层构成第一重过滤，滞留层包括人工填料层和淹没区，人工填料层构成第二重过滤，淹没区构成第三重过滤，雨水依次经过第一重过滤、第二重过滤和第三重过滤过滤后从排水层离开。本发明相较于现有技术在滞留层内增设了淹没区，进而提高了对硝态氮的去除效果。
