摘　　要：设置了不同基质(砾石、加气混凝土)及是否种植美人蕉的不同人工湿地结构,通过小试实验对比各个工况对雨水径流污染的阻控效果.研究发现,加气混凝土与种植美人蕉的人工湿地组合成本略高(4.20元/工况),较其余工况高出1.00~2.90元/工况,但在运行的两个周期(交替运行30 h,落干48 h)内,NH_(4)^(+)-N、NO_(3)^(-)-N、TN、PO_(4)^(3-)、TP和COD_(Cr)的平均去除率分别为73.3%、47.0%、85.4%、56.4%、76.0%和65.5%,平均高出其余工况10.9%~18.8%,效果最优,性价比最高,适于推广应用.In this study,constructed wetland structures were established using different substrates(gravel and aerated concrete),with or without cannas planting.Subsequently,the effects of different working conditions on rainwater runoff pollution were investigated through small experiments.The cost of the constructed wetland with aerated concrete and cannas(4.20 yuan/working condition)was slightly higher(1.00~2.90 yuan/working condition higher)than those under other working conditions.However,in both cycles of operation(i.e.,alternating operation for 30 h and drying for 48 h),the average removal rates of NH_(4)^(+)-N、NO_(3)^(-)-N、TN、PO_(4)^(3-)、TP and COD_(Cr) were 73.3%,47.0%,85.4%,56.4%,76.0%,and 65.5%,respectively.These values were higher than those under other working conditions by an average of 10.9%~18.8%.Thus,this constructed wetland structure had the best effect and the highest cost performance.Therefore,it is suitable for promotion and application.
