摘　　要：对准好氧垃圾填埋所产生的垃圾渗滤液进行全循环处理,考察了水力负荷和回灌次数对渗滤液除污效果的影响。正交试验结果表明,水力负荷是影响渗滤液中污染物去除效果的关键因素,回灌次数则为次要因素;较优的水力负荷和回灌次数分别为15.9 L/(m2.d)和3次/d,此时对渗滤液中COD、BOD5、NH4+-N的去除率分别为99.3%、99.7%和98.7%。An orthogonal test simulating quasi-aerobic full-scale landfill leachate recirculation was conducted. The factors influencing leachate treatment investigated were the hydraulic load and recirculation frequency. The results show that the hydraulic load is the critical factor in determining the pollutants removal. Hence, the recirculation frequency is the secondary factor. The optimal hydraulic load and recirculation frequency concluded are 15.9 L/（m^2 · d）, and 3 times/d, respectively. The removal percentages of COD, BOD5 , NH4^＋ - N under the conditions are 99.3% , 99.7% , 98.7% , respectively.
