Constructed wetlands (CW) with vertical flow were used to treat leachate from municipal landfills (active and closed, at different concentrations) using a combination of substrates, i.e., gravel, sand and an exchangeable layer, depending on a variant: organic substrate (pine bark) or mineral substrate (zeolite, expanded clay). The systems were planted with Phragmites australis. The aim of this study was to compare the efficiency of removal of selected pollutants from landfill leachate in CW using different types of filling. For most parameters, the best reductions were obtained on zeolite substrates. In the investigated CW, reductions were achieved at the levels of: AN 96%-99%; TKN 75%-88.5%; TN 62.5%-70%, TP 84-88% and heavy metals (Zn, Ni, Cu, Cr) 41%-56%.
垂直流人工湿地被用于处理来自城市垃圾填埋场（活跃和封闭的，浓度不同）的渗滤液，使用了多种基质的组合，即砾石、沙子和一个可交换层，具体取决于不同变体：有机基质（松树皮）或矿物基质（沸石、膨胀粘土）。这些系统种植了芦苇。本研究的目的是比较使用不同类型填料的人工湿地去除垃圾渗滤液中选定污染物的效率。对于大多数参数，在沸石基质上获得了最佳的去除效果。在所研究的人工湿地中，去除率达到以下水平：氨氮96%-99%；总凯氏氮75%-88.5%；总氮62.5%-70%，总磷84%-88%以及重金属（锌、镍、铜、铬）41%-56%。
