Bioretention system
The invention discloses a bioretention system, the bioretention system comprises a retention pond body and a reservoir, a water outlet pipe used for draining water to the reservoir is arranged at thebottom of the retention pond body, the retention pond body comprises a retention area, a gravel supporting area and a flow slowing area arranged between the retention area and the gravel supporting area, and the flow slowing area is used for delaying sewage in the retention area from flowing into the reservoir. According to the technical scheme of the bioretention system, a number sign-shaped partitioning unit is used for partitioning planting soil filler on the upper layer of the bioretention pond, filling of the high-permeability and high-adsorbability filler is alternately conducted, so that the function of planting soil for planting plants is reserved, and the advantages that part of rainwater can be preferentially stored by the partitioning unit during high-intensity rainfall, transverse and longitudinal infiltration is performed, the anti-overflow capacity of a facility under an extreme rainstorm condition is remarkably improved, the rainwater runoff retention and storage capacity and the water quality purification capacity are improved, and particulate matter blockage is prevented are achieved; and meanwhile, the structure is simple, installation is convenient, and the maintenance efficiency of the facility is remarkably improved.
本发明公开了一种生物滞留系统，包括滞留池本体和蓄水池，所述滞留池本体底部设置有用于向蓄水池排水的出水管；所述滞留池本体包括滞留区、砾石承托区以及设置于滞留区与砾石承托区之间的缓流区，缓流区用于延缓滞留区中的污水流入所述蓄水池，本技术方案的生物滞留系统采用“井字型”分块单元将生物滞留池上层种植土填料进行分块，并交替性的填充高渗透、强吸附性填料，不仅保留了种植土用于种植植物的功能，也可在高强度降雨时，分块单元优先贮存部分雨水，并进行横向及纵向入渗，显著提高设施在极端暴雨条件下的抗溢流能力，提高雨水径流滞蓄能力、水质净化能力及预防颗粒物堵塞的优点，同时其结构简单、安装方便，显著提升设施的养护效率。
