Through soil infiltration filter system，the effects of difference dry-wet ratio on the removal efficiency of subsurface
infiltration system ( SIS) were discussed． At the hydraulic loading of 0. 08 m3
/ ( m2
d) ，five kinds of operating conditions
were set up，dividing the continuous operation and four dry-wet ratio conditions ( 1 ∶ 2，1 ∶ 1，2 ∶ 1 and 3 ∶ 1) ． The results
showed that intermittent running was a positive method to enhance the removal efficiency of SIS． The dry-wet ratio of 1∶ 1 had
the best removal efficiency that COD，ammonia nitrogen，TN and TP removal rates reached 90%，95%，70% and 90%
respectively． Dry-wet ratio of 1∶ 1 in SIS was suggested when used in the north area predominantly sandy soil．
