摘　　要：将波形潜流人工湿地(wavy subsurface flow constructed wetland,简称W-SFCW)在相同条件下与水平潜流人工湿地进行对比试验.W-SFCW床优化了传统潜流人工湿地的水流流态,使污水在W-SFCW床内进行波式流动,充分发挥了湿地系统降解污染物的能力.试验结果表明:W-SFCW在污染物去除方面明显优于传统潜流人工湿地.在相同试验条件下,W-SFCW对污水中COD,NH4+和TP的去除率分别比SFCW提高12.6％,22.0％和8.4％.A new type of constructed wetland system for sewage treatment, called wavy subsurface flow constructed wetland (W-SFCW), was studied and paralleled with horizontal subsurface flow constructed wetland (SFCW) at same test conditions. Main characteristics of W-SFCW are optimal flow-state on wastewater and domestic sewage flow wavily in W-SFCW bed. So the efficiency of constructed wetland for pollutant removal is higher. Experiment shows that the removal efficiency of W-SFCW bed on COD, NH4+ and TP are 12. 6%, 22. 0% and 8. 4% higher than that of SFCW.
