摘　　要：采用削减系数法及主成分分析法,对人工湿地不同工艺组合去除COD、BOD、NH3-N、TN、TP、SS的经济效益进行比较分析.以西安皂河实验人工湿地的五种不同组合类型为例,通过计算分析得出:垂直潜流+水平潜流人工湿地的组合的经济效益最优,适宜于北方地区废水处理.Economic efficiency of COD, BOD, NH3-N, TN, TP, SS removal in different combined process of constructed wetland by using the method of reduction factor and principal component were analysed. Xi＇an Zaohe River experimental constructed wetland was used as a case. The results showed that the composite economic efficiency of horizontal and verti cal sub surface flow constructed wetland system is the best, and this combined process is suitable for the wastewater treatment in China＇s northern regions.

关 键 词：人工湿地 组合工艺 经济效益 削减系数
