Title: Influence of Recirculation Operations to the Output of Leachate in Initial Landfill Stage
Abstract: Experiments were conducted through simulation columns (with 170 kg of waste) to simulate the infiltration of rain, direct recirculation of the leachate without any pretreatment, recirculation of the leachate pretreated by aerobic biodegradation. The results indicate that ① the output rate of leachate in the initial landfill stage can be enhanced through recirculation of leachate.②The net output of leachate in the initial landfill stage is depended on not only volumes but the quality of recycled leachate. ③Microbial hydrolyzation is restrained and the net output of leachate is reduced by direct recirculation of the leachate without any pretreatment after four weeks.④Through recirculation of the leachate pretreated by aerobic biodegradation, it helps to improve microbial hydrolyzation, which can accelerate the output of leachate, and hereafter improve the hydrolyzation of nondegradable substance, namely to increase the cumulate volume of the net output of leachate.⑤Gompertz model can be used to simulate the rule of cumulate volume of the net output of leachate with time in the landfill layer by different recirculation operations.
