摘　　要：在序批式工况下,研究了深床过滤型垂直流人工湿地(深度1.5 m,C系统)相对常规0.5 m(A系统)和1.0 m床深(B系统)湿地对进水中主要污染物的净化效果和堵塞过程。结果表明,C系统污染物整体去除效果最优。A,B,C系统分别在运行约140,155,175天后严重堵塞,各系统总处理水量A B C=1.0 2.1 3.2,深床过滤垂直流人工湿地能一定程度延缓湿地堵塞,增加水处理量,水力负荷一定时,可有效减少湿地建设面积。The purification efficiency of main pollutants and clogging process of deep - bed filtration （ 1.5 m, system C） vertical flow constructed wetland （VFCW） compared with conventional 0.5 m （ system A） and 1.0 m deep bed （ system B） VFCWs under continuous batch condition has been investigated. The results show that the overall removal efficiency of pollutants of system C is better than that of system A and B. Systems A, B and C are se- riously clogged after operated for about 140, 155, 175 days respectively, and the ratio of total wastewater treated for the systems is ： A ： B ： C = 1.0 ： 2.1 ： 3.2. Thus, the deep - bed filtration VFCW can delay the clogging process to certain extent and increase the amount of wastewater treated, and under set hydraulic load, it can effectively reduce the wetland construction area.
