摘　　要：采用2个微曝气(0.1 L/min)矿化垃圾反应器处理渗滤液,研究进水频次对矿化垃圾处理渗滤液效果的影响。结果表明:在进水频次为1次/d和2次/d的条件下,提高进水频次可促进COD、NH4+-N和总磷的去除,促进NO2--N向NO3--N的转化,但对总氮的去除无促进作用。进水频次2次/d时,COD、NH4+-N和总磷的平均去除率分别达到83%、95.8%和96%,高于进水频次1次/d的68%、88.3%和87%。但两者总氮平均去除率相差不大,进水频次1次/d时总氮平均去除率为48.7%,高于进水频次2次/d的46.4%。Two micro-aeration aged refuse reactors with air flow rate 0.1 L/min were constructed and the impact of irrigation frequency on leachate treatment by them was investigated. Results indicated that the increase of irrigation frequency could promote the removal of COD, NH4^＋-N by facilitating the conversion of NO2^--N to NO3^--N, and TP, while the disposal of TN was hardly influenced. When the irrigation frequency was 2 times each day, average removal rates of COD, NH4^＋-N and TP reaching up to 83%, 95.8% and 96% were better than that irrigating leachate 1 time each day with the corresponding removal rates of 68%, 88.3% and 87%. However, the average removal rate of TN in the two reactors was close, attaining to 48.7% and 46.4% respectively.
