摘　　要：通过对渗沥液回灌过程的模拟试验,研究了不同的渗沥液回灌液类型、回灌频率和回灌量对堆酵效果的影响。结果表明:新鲜渗沥液的回灌有利于加速生化反应,缩短垃圾堆酵的时间;回灌量与垃圾的最佳比例须根据实际情况确定;加大回灌频率有利于提高垃圾降解速率。本试验装置回灌最佳条件为:新鲜渗沥液作为回灌液,回灌量为6.000 kg,回灌频率为3次/d。The effect of ditferent recirculating liqmd, reclrculatlon frequency and quantity on waste stacking anu fermenting was studied by simulating leachate recirculation process. The results indicated that the fresh leachate recirculation can advance biochemical reaction and shorten waste fermentation time. The ratio of reeirculation quantity and waste quantity should be determined according to the actual circumstances. Increasing frequency of recirculation could be in favor of improving waste degradation rate. Optimal conditions of the test device were fresh leachate as the recirculating liquid, recirculation quantity of 6.000 kg, reeirculation frequency for 8 hours per time.
