摘　　要：[目的]研究砾石潜流-浮桥平流复合湿地系统对生活污水的净化效果。[方法]人工组建砾石潜流-浮桥平流复合湿地系统,以生活污水为研究对象,考察该系统对污水中化学需氧量(COD)、氨氮(NH_3-N)、总氮(TN)、总磷(TP)的净化效果。[结果]系统对生活污水中COD、NH_3-N、TN、TP的平均去除率分别为73.3%、56.1%、47.1%、65.7%;一级湿地单元对COD的去除效果较好,二级湿地单元对NH_3-N、TN和TP的去除效果较好,三级湿地单元对各项污染指标的去除率均较差。[结论]砾石潜流—浮桥平流复合湿地系统对生活污水整体净化效果良好,可拓展研发新型生态污水处理技术。[Objective] The purification effect of gravel subsurface flow-floating bridge advection composite wetland system on domestic sewagewas studied.[Method] We constructed a gravel subsurface flow-floating bridge advection composite wetland system and took domestic sewage asthe research object, to observe the purification effect of the system on COD, NH3-N, TN and TP in sewage.[Result] The average removal ratesof COD, NH3-N, TN and TP in domestic sewage were 73.3%, 56.1%, 47.1% and 65.7%, respectively. The first level wetland unit had betterremoval effect on COD. The second level wetland unit had better removal effect on NH3-N, TN and TP. The third level wetland unit had poor re-moval rates for all pollution indicators.[Conclusion] Gravel subsurface flow floating bridge advection composite wetland system has good effect ondomestic sewage purification and can develop new ecological sewage treatment technology.
