摘　　要：通过建设5个系列不同组合复合人工湿地中试工程,考察复合人工湿地对受污染河水的净化效果及人工湿地污水处理最佳组合形式,为渭河大型人工湿地群建设提供技术支持。研究结果表明,成熟复合人工湿地各系列对COD、BOD5的平均去除率一般可达80%、85%,NH4+-N、TN、TP的平均去除率除系列1、2外,其它各系列一般可达80%。在皂河入渭口建设人工湿地能有效改善渭河水体水质,可以在渭河湿地群建设中采用。Five groups of different hybrid constructed wetlands were constructed. The purification efficiency of polluted river water, optimum combination, design and operation parameters of the constructed wetland were investigated to provide technical support for establishment of the large-scale constructed wetlands in Weihe river Shaanxi China. The results shows that the integrated constructed wetland can remove COD, BOD5 with the average removal rate of 80%, 85% in every Series during maturation, NH4^＋-N, TN, and TP with the average removal rate of 80% besides Series 1 and Series 2. It＇s showed that the integrated construction artificial nearby Weihe river Shaanxi can greatly improve the water quality in Weihe river and should be adopted in the Weihe river wetland cluster construction in the future.
