The main purpose of this study was to investigate the removal of ammonia, orthophosphate, and COD present in landfill leachate using vertical subsurface flow constructed wetland systems (VFCW). The effect of different types of plants () in the removal of pollutants was also investigated. The systems were operated identically at a flow rate of 5 l/day and a hydraulic retention time (HRT) of 22 days in the reactor (R1), reactor (R2), and Control reactor (R3). Concentration-based average removal efficiencies for R1, R2, and R3 were NH-N; 60.0%, 56.0%, and 46, COD; 81.0%, 84.0%, and 79.0%, PO-P; 45.0%, 46.0%, and 32.0%, respectively. These results show that the model is a good predictive tool for determining the plant lengths using the growth equations. It is also revealed that the Logistic and Cubic models are suitable for the R1 and R2 reactors.
本研究的主要目的是利用垂直潜流人工湿地系统（VFCW）去除垃圾渗滤液中的氨、正磷酸盐和 COD。还研究了不同类型植物对去除污染物的影响。三个反应器（R1、R2 和 R3）以相同的条件运行，水力停留时间（HRT）为 22 天，流量为 5 l/天。R1、R2 和 R3 的基于浓度的平均去除效率分别为 NH-N：60.0%、56.0%和 46.0%；COD：81.0%、84.0%和 79.0%；PO-P：45.0%、46.0%和 32.0%。结果表明，该模型是使用生长方程确定植物长度的良好预测工具。还表明，Logistic 和 Cubic 模型适用于 R1 和 R2 反应器。
