摘　　要：采用人工处理池,将水平流与垂直流湿地系统组合成复合式人工湿地处理系统,研究了此系统在停留时间为5d时对城市污水的净化效果。结果表明,水平流-垂直流复合人工湿地系统处理效果相当稳定,其对化粪池出水中COD,BOD5,TP,TN,SS的平均去除率分别为72%,80%,83%,33%和60%以上。而种植系统去除效果明显高于无种植系统。The integrated wetland systems were constructed by combining horizontal- flow and vertical- flow bed, and their purification efficiencies for septic tank effluent were detected when the hydraulic retention time (HRT) was five days. The results showed that horizontal- flow and vertical- flow beds had very stable effects on the removal of COD, BOD5, TP, TN and SS .The average removal rates of COD, BOD5, TP, TN and SS were over 72% , 80% , 83% , 33% and 60% , respectively, and the removal effects of plant- systems were greater than that of the control (no plant growing system).
