摘　　要：针对我国生活污水处理现状及要求,对比研究了普遍推广的人工湿地技术与新兴的土壤净化槽技术,发现在进水水质、环境条件均相同的情况下,上行流人工湿地处理效果优于下行流人工湿地;基质按照不同需氧层铺设不同粒径填料的土壤净化槽处理效果优于基质直接分层铺设填料的土壤净化槽;土壤净化槽和人工湿地出水水质都很好,出水CODCr、TN、TP、氨氮分别达到了二级、一级A、一级B、一级A标准;土壤净化槽装置占地面积小,为人工湿地的2/3.土壤净化槽技术是适合我国国情的有发展前景的生活污水处理技术.In view of the status quo and requirements of domestic sewage treatment,the technology of widespread constructed wetland（CW） and emerging soil trench（ST） are comparatively studied.It is found that under the circumstance of same inflow qualities and environmental conditions,upward flow applied in CW treatment is better than the downward flow;matrix consists of different sizes of granules according to different aerobic layers have better performance in ST treatment than direct layered matrix;the effluent qualities of both treatments are close,in which the CODCr,TN,TP,NH＋4-N reach the standard Ⅱ,Ⅰ（a）,Ⅰ（b）,Ⅰ（a） respectively;the occupied area of ST facilities is 1/3 smaller than that of CW;and the soil trench is one of the promising technologies of domestic sewage treatment suitable for national conditions.
