摘　　要：采用模拟试验装置考察回灌频率与回灌水力负荷对新鲜垃圾柱渗滤液的影响,试验结果表明:高频率回灌将导致新鲜垃圾柱渗滤液初期酸化阶段的低pH值和甲烷化阶段的高pH值。高水力负荷将导致新鲜垃圾柱渗滤液pH值下降。因此在新鲜垃圾填埋单元自身回灌初期应采取低频率小水力负荷。The effects of recirculation hydraulic load and frequency on leachate from fresh municipal refuse were investigated in a bench-scale experiment.Recrirculation hydraulic load and frequency can affect quality of leachate from fresh refuse.It is testified that higher hydraulic-load results in lower pH,and higher recirculation frequency results in lower pH during hydrolysis and acidification phase,higher pH during methanation phase.So during the start stage of leachate recirculation to the new landfilled refuse cell,low hydraulic load and low frequency should be adopted.
