利用沈阳市满堂河污水处理中心人工湿地8年来运行数据,对人工湿地整体系统和不同功能区的水质净化效果进行了对比分析,结果表明,潜流人工湿地对COD(Cr)的去除效率,在50%～70%;表面流人工湿地对COD(Cr)的去除效率,稳定在20%左右;人工湿地系统整体对悬浮物和氨氮的去除效率保持在50%以上;人工湿地系统对污染物质的去除效率,随着运行时间增加而日趋稳定.%Based on the long-term water quality monitoring data in Shenyang Mantang river wastewater treatment center,water quality purifying effect of overall constructed wetland system and different function regions were analyzed. The results showed that CODCr removal rate reached 50％～70％ in subsurface flow constructed wetland, CODCr removal rate reached about 20％ steadily in surface flow constructed wetland, SS and NH3-N removal rates reached over 50％ of the total constructed wetland. The removal rates of contaminants in constructed wetland system were stable gradually with running time increasing.
