摘要
将模拟准好氧填埋场垃圾渗滤液进行全循环回灌处理,考察了不同回灌条件对渗滤液稳定化进程的影响。结果表明,不同回灌条件下垃圾渗滤液具有基本相同的稳定化进程,COD和BOD5值均经历了快速下降、稳定下降和缓慢下降3个时期;而氨氮浓度则是先升高后降低。每日回灌总量和回灌频率是影响渗滤液稳定化进程的主要因素:在一定范围内,二者取值越大则渗滤液的稳定化程度越高。
Fully recycling treatment of semi-aerobic landfill leachate was carried out. The influence of different recycling conditions on the leachate stabilization was investigated. The results show that the leachate has similar stabilization under different recycling conditions. COD and BOD5 values experience three periods of rapid decrease, stable decrease and slow decrease. Ammonia nitrogen experiences an early fast and later slow degradation. The main factors which affect the leachate stabilization are recycling quantity and recycling frequency. Under a certain range, higher recycling quantity and recycling frequency can result in higher leachate stabilization.
