新鲜垃圾渗滤液的自然衰减与渗滤液自身回灌法降解的比较

Comparison of the Natural Attenuation of Fresh Landfill Leachate and the Degradation of Leachate Recirculation

通过对实验所得数据进行分析,发现准好氧填埋场渗滤液自然衰减速度快于厌氧填埋场渗滤液的自然衰减速度;渗滤液自然衰减的速度远远小于回灌型厌氧填埋场渗滤液的降解速度,更小于回灌型准好氧填埋场渗滤液的降解速度。渗滤液回灌的方法可以加速填埋场垃圾的降解,部分解决垃圾填埋场渗滤液处理困难的问题。

Experimental resuhs showed that the natural decay rate of semi-aerobic landfill leaehate is faster than that of the anaero- bit＇, landfill leachate; the natural decay rate of leachate is slower than the degradation rate of recirculation anaerobic landfill leachate, and is much slower than that of recirculation semi-aerobic landfill leachate. Leachate recirculation can accelerate the degradation process in landfill, which partially resolves the difficulties of landfill leachate treatment.
