摘　　要：根据稳定表流湿地新技术,对比研究了折流式稳定表流湿地和推流式稳定表流湿地处理生活污水中有机物、SS、氮和磷的去除效果及其影响因素。在水力负荷为0.53 m3.m-2.d-1,处理低浓度生活污水试验研究结果表明,推流式稳定表流湿地对COD、TP、NH3-N、SS去除率分别为63.8%、20.2%、2.14%和65.8%,折流式稳定表流湿地相应的去除率分别为73.4%、20.61%、2.69%和73.6%,折流式稳定表流湿地对4种污染物的去除效果优于推流式稳定表流湿地。This paper introduced a new wastewater treatment process which named stable surface flow wetland. Meanwhile, we discussed the removal rate of organic substance, suspended solids, nitrogen and phosphorus in the folds stable surface flow wetland （FSSFW） and the pushing stable surface flow wetland （PSSFW） comparatively for domestic sewage treatment. Also, the influence factors during this treatment process had been studied. Under the hydraulic loading of 0.53 m3.m-2.d-1, the results of experiment indicated that the removals of COD,TP,NH3-N,SS of PSSFW were 63.8%,20.2%, 2.14% and 65.8%, raspcctively, the corresponding removals of FSSFW were73.4%, 20.61%, 2.69% and 73.6%, respectively, and FSSFW surpassed PSSFW in terms of removals of all the four pollutants.
