摘　　要：根据厌氧、好氧以及准好氧生物反应器填埋场的特点,结合农村地区生活垃圾处理现状,开展了厌氧-准好氧生物反应器处理农村生活垃圾产酸期最优工况的室内模拟试验。研究表明,影响COD去除率的影响因素依次为回灌频率、p H、曝气时间以及回灌比例;影响氨氮去除率的影响因素依次为p H、回灌比例、回灌频率以及曝气时间。由综合平衡法分析得出在回灌频率3 d/次,回灌比例75%,p H值调节为8.0,渗滤液回灌前曝气10 min时,对于产酸阶段的厌氧-准好氧联合型生物反应器填埋场运行情况最佳。Based on the characteristics of anaerobic, aerobic and semi-aerobic bioreactor landfill, indoor simulation experiment on the optimal condition of acidification phase during the treatment of rural domestic waste was carried out. Combined anaerobic with semiaerobic bioreactor was used. Results show that the factors affecting COD removal rate in descending sequence are recirculation frequency, pH, aeration time and recirculation ratio, while it shows a descending sequence of pH, recirculation ratio, recirculation frequency and aeration time for ammonia nitrogen removal rate. By the analysis of comprehensive balance, the best conditions for the operation effects of land-fill are 3 d per time for recirculation frequency, 75% for recirculation ratio, pH 8. 0 and 10 min aeration time.
