摘　　要：在对北方某人工湿地长期观测取得的大量详尽数据的基础上,分析了人工湿地系统总体净化能力和潜流人工湿地水质动态变化特征。结果表明:该人工湿地示范工程对水质净化效果较为明显,对各类污染物的去除率平均可达40%;潜流人工湿地可对污水进行深度处理,对BOD5、NH4-N的去除效果最好,去除率为80%～90%,对NO3-N、TN的去除效果较好,去除率为65%～75%,对CODMn和SS的去除效果一般,去除率为40%～60%,对TP的去除效果随着时间推移逐渐减弱,碎石吸附对TP去除起主要作用。Based on the long-term monitoring water quality data in northern constructed wetland,the overall purification capacity of constructed wetland system and dynamic characteristics of water quality along the way were analyzed.The results show that removal rate of contaminants reachs more than 40% averagely.Subsurface flow constructed wetland can be the depth of sewage treatment,BOD5 and NH4-N removal rate of the most significant,basically 80% to 90%;NO3-N and TN are better,the removal rate are 65%-75%;CODMn and SS removal are in general,the removal rate are 40% to 60%.Subsurface flow constructed wetlands for the removal rate of TP over time,gradually weakening the adsorption of TP removal of gravel from the major role.
