Abstract: Using semi-aerobic aged refuse reactor to deal with landfill leachate,the denitrification property of aged refuse with different particle sizes（＜4 mm、4 ~10 mm、10 ~20 mm） was studied. The results showed that the removal effect of aged refuse with granularity of 4 ~10 mm on COD and NH3-N was better than that of other granularities. Under the conditions of hydraulic loading at 2 L/d and influent frequency at one time per day,92% of NH3-N and 65% of COD in leachate were removed by the aged refuse of 4 ~10 mm.
