Rain flood bioretention pond-infiltration canal recharge structure
The invention discloses a rainfall flood bioretention pond-infiltration canal recharge structure in the technical field of rainfall flood resource recharge, and aims to solve the problems that a recharge structure in the prior art is low in rainfall flood resource recharge rate, cannot adjust the recharge mode and the recharge depth according to different rainfall amounts, is poor in recharge water quality, high in recharge structure cost and the like. The biological detention pond comprises a biological detention pond body and an infiltration canal structure, and the biological detention pond body is embedded below a stratum and sequentially comprises a water storage area, a planting soil layer, a biological carbon matrix layer and a divalent iron ore matrix layer from top to bottom; the seepage ditch structure comprises a shallow underground water conveying pipe and a deep underground water conveying pipe, the shallow underground water conveying pipe is connected with the planting soil layer, the deep underground water conveying pipe is connected with the divalent iron ore matrix layer, and the other ends are connected with the far-end underground water storage space. The efficiency of removing ammonia nitrogen, total phosphorus and organic pollutants in recharge water can be greatly improved, meanwhile, different water conveying modes of the infiltration canal structure can be controlled according to the rainfall, and underground water of different depths can be efficiently recharged.
本发明公开了一种雨洪资源回灌技术领域的雨洪水生物滞留池‑渗渠回灌结构，旨在解决现有技术中回灌结构针对雨洪资源回灌速率慢，无法针对不同雨量调整其回灌方式和回灌深度，回灌水质差和回灌结构造价高等问题，其包括生物滞留池和渗渠结构，生物滞留池嵌设于地层之下，其从上到下依次包括储水区、种植土层、生物炭基质层和二价铁矿基质层；渗渠结构包括浅层地下水输水管和深层地下水输水管，浅层地下水输水管与种植土层连接，深层地下水输水管与二价铁矿基质层连接，另一端均连接远端地下储水空间。本发明能大幅提升对回灌水氨氮、总磷、有机污染物去除效率，同时能够根据雨量的大小控制渗渠结构的不同输水方式，高效回灌不同深度的地下水。
