摘　　要：以厌氧沉淀塘、垂直潜流湿地、水平潜流湿地、表流湿地和生态景观塘为单元构建了4种不同工艺组合的人工湿地系统并应用于生活污水除氮实验研究,连续一年的实验监测结果表明:不同工艺组合人工湿地系统对生活污水除氮效果差别明显,以潜流湿地为单元构建的CW4系统对污水中氨氮和总氮的去除效果最好,分别为52. 23%~82. 46%和38. 72%~88. 46%;而CW3和CW1系统对污水中氨氮和总氮的去除率最差。此外,不同人工湿地系统在不同季节对生活污水除氮效果差异较大。Based on the units of anaerobic sedimentation reservoir,vertical subsurface flow wetland,horizontal subsurface flow wetland,surface flow wetland and ecological landscape reservoir,these four different processing combined constructed wetland systems were established and applied for removing nitrogen from sewage. The one year continually experimental monitoring showed that different processing combined constructed wetland systems achieved different nitrogen removal efficiency. On the basis of subsurface flow wetland unites,the established CW4 system had highest removal efficiency for ammonia and total nitrogen,with a percentage of 52. 23% ~ 82. 46% and 38. 72% ~ 88. 46% respectively. However,the CW3 and CW1 systems achieved the lowest removal efficiency for ammonia and total nitrogen,33. 46% ~ 67. 42% and 12. 32% ~ 61. 43% respectively. Additionally,different seasons greatly affected all the constructed wetland systems removal efficiency for ammonia and total nitrogen. The systematically and comparatively experimental research proved that the based vertical and horizontal subsurface flow constructed wetland system has higher removal efficiency for nitrogen and better application prospect.
