摘　　要：介绍了一种改进的人工湿地,该湿地在传统潜流湿地的基础上,提高水流曲折性,改用波形方式的流态,使污水反复多次地经过土壤基质,从而增强了吸附、沉淀的效果,更为有效地提高污染物的去除效果。通过实验将传统湿地和波形湿地进行比较,发现波形湿地出水COD和NH4+-N明显低于传统湿地。On the base of the traditional subsurface constructed wetland （SFCW）, this study introduced an improved subsurface constructed wetland-Wavy subsurface constructed wetland （W-SFCW）, which made the flow flexuous, adopted wavy mode, so that the sewage could pass through the soil and fillings repeatedly, therefore, it advance the efficiency of adsorptions and depositions and raised the removal efficiency on waste matters. In this discussion, W-SFCW was paralleled with SFCW through experiment, the data showed that the outflow of W-SFCW is lower than that of SFCW.
