| 摘 要： | 研究了单级垂直向上流(vertical up-flow, VUF)和单级垂直向下流(vertical down-flow, VDF)潜流式人工湿地组合在不同进水负荷条件下的污染物降解效果.结果表明,VDF-VUF人工湿地组合是最优的两级垂直潜流式人工湿地组合,在进水负荷(C/N=5)条件下其可以达到最好的污染物去除效果.COD和TN的去除率都受到了季节变化、湿地系统组合变化以及两者的综合作用的显著影响(PPP<0.05).

| Abstract: | The combinations of two stage vertical-subsurface flow constructed wetlands, i.e. vertical up-flow (VUF) and vertical down-flow (VDF), can achieve high nutrient removal efficiency. The optimal combination is VDF-VUF; and the optimal influent C/N ratio is C/N=5. The removal efficiencies of chemical oxygen demand and total nitrogen are significantly affected by season variation, constructed wetlands combination, and the combined effect of them.The total phosphorus removal efficiency is only significantly affected by season variation; the total organic carbon removal efficiency is significantly affected by season variation and constructed wetlands combination. |
