5 ℃) , an indoor simulation system was constructed with effluent sample collected from a rural septic tank and in-situ surface soil at the sewage drain, and the transformation of nitrogen of sewage through soil filtration process was discussed. The results showed that, the nitrogen of rural septic tank effluent was mainly dissolved inorganic nitrogen(DIN) , and NH+

4 -N accounted for more than 70% of DIN, an insignificant difference (P>0.05, n=12)in DIN concentrations and a significant difference (P0.05, n=12) , NH+ 4-N、 NO- 2-N、 NO- 3-N浓度均具有极显 著性差异 (P
