摘　　要：采用三段式水平潜流人工湿地处理生活污水,具有较强的抗污染负荷冲击能力,出水水质可达GB 18918—2002一级A标准。人工湿地对COD_(Cr)的去除规律符合一级反应,COD_(Cr)与长度的关系为C_i-C_*=90.356L^(-0.5201)。Three-section subsurface flow constructed wetland was applied to treat donmestic sewages. The wetland has the strong capacity in resistance to shock loading of pollutant,and the effluent quality sat- isfies the I-class A criteria of GB 18918-2002.The equation of COD_(Cr) concentration degraded by construe- ted wetland is C_i-C_*=90.356L^(-0.5021),which is first-order reaction.
