不同填料垂直流人工湿地系统的净化能力研究OA北大核心CSCDCSTPCD
A Study on Purification Capacity of Different Substrates on the Treatment Performance of Vertical Flow Constructed Wetland
以火山石、沸石、牡蛎壳、陶粒、麦饭石和砖红壤作为人工湿地填料,在水力负荷( 0.5～1.5 m/d)的条件下,构建垂直流人工湿地模拟系统,进行单一填料和组合填料的污水净化实验.结果表明,单一填料砖红壤、牡蛎壳、陶粒和麦饭石人工湿地系统对有机物去除能力较好,COD的去除率在40％以上.砖红壤、麦饭石和沸石对总氮的去除率达到39％以上,火山石29％,牡蛎壳和陶粒填料对总氮去除率均低于20％.除砖红壤具有较好去除磷的能力86％外,其余填料系统对磷的去除…查看全部>>
Several kinds of substrates were utilized in the vertical flow constructed wetlands simulation system to compare the purification capacity of single packing and combination packing by treating artificial sewage at hydraulic loading rate of 0. 5 ～1.5 m/d, including volcanic rock, zeolite, oyster shells, ceramsite, medical stone and laterite. The results showed that the COD removal efficiency was more than 40% in the single packing constructed wetlands of late…查看全部>>
