摘　　要：介绍了沈阳浑南人工湿地示范工程的运行效果，为北方寒冷地区应用湿地技术处理生活污水提供了技术支持与保证。当进水COD为182～423mg／L、NH3-N为42．0—69．45mg／L、TP为4．11～8．0mg／L时，对上述指标的平均去除率分别为90．85％、98．38％、89．68％，出水水质达到国家排放标准。在冬季增加保温措施后，垂直流人工湿地不仅可以安全越冬，利用水流的进入和排出还可有效地与大气进行气体交换，缓解床体内氧气的不足，大大提高对污染物的去除率，达到与其他季节相近的处理效果。The operation effect of Hunnan constructed wetland demonstration project is introduced to provide technology support and guarantee for the application of construction wetland to treatment of domestic sewage in cold climate in northern region. When the influent COD, NH3 -N and TP are 182 to 423 mg/L, 42.0 to 69.45 mg/L and 4. 11 to 8.0 mg/L, their average remove rates are 90.85% , 98.38% and 89.68% respectively, and the effluent quality meets the national discharge standard. The Hunnan vertical-flow constructed wetland can survival through the winter with certain heat preservation measures, exchange air by making use of influent and effluent flow, compensate the oxygen inadequacy of the bed, which improves the removal rates of contaminants and reaches the similar treatment effect to other seasons.
