摘　　要：用准好氧矿化垃圾反应器来处理垃圾渗滤液，研究4mm以下、4～10mm、10～20mm三种粒径的矿化垃圾对渗滤液的脱氮性能。结果表明：在水力负荷2L／d，进水频率1次／d的条件下，粒径为4—10mm的矿化垃圾处理渗滤液的效果最好，其渗滤液出水中氨氮和COD去除率分别达到92％和65％以上。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 nun.
