摘要
人工湿地污水处理系统作为一种处理成本低、运行费用低、效率高和管理方便的污水处理技术,具有良好的应用前景。污水中的磷主要是通过湿地植物的积累和吸收作用、微生物的生物化学作用以及基质的吸附、络合和沉淀作用共同完成的。本研究主要通过正交试验的方式,在水力负荷(HLR)、基质、植物以及湿地类型几个条件中,筛选出人工湿地系统去除总磷的最优方案。实验结果显示,种植再力花的基质为沸石且水力负荷为0.125 m/d的下行垂直潜流人工湿地系统具有最佳的去除总磷的效果。
the Constructed wetland,as a kind of low cost,convenient operation,high efficiency and manageable sewage treatment technology,will show better practical value and promising future in these fields.The phosphorus in sewage is removaled by the accumulation and absorption of the plants,the biochemistry of microbial,and the adsorption,complexation,precipitate of substrate.By orthogonal experiment,the hydraulic load（HLR）,substrates,plants and wetland types were investigated in this study.Which affect the efficiency of the constructed wetland system,confirms the optimal scheme of removal of total phosphorus.The results show that,the downward vertical undercurrent wetlands with thalia dealbata,zeolite as the substrate and hydraulic load of 0.125m/d,is the best scheme.
