Abstract

Through two sets of batch bioreactor landfill simulation devices,the paper studies the change law of the leachate pH,CODCr,NH4+-N,VFA and the leachate production in early landfill MSW degradation.The experimental results show that: this mode can inhibit the rapid decline of leachate pH in initial landfill,to take part of leachate recirculation can reduce the accumulation of NH4+-N effectively,70% recirculation quantity can improve the water quality of leachate significantly than 50%.
