模拟生物反应器填埋场产甲烷特征研究

Research on Characteristics of Methane Generation in Simulated Bioreactor Landfill

通过模拟实验,对渗滤液回灌频率及回灌前对渗滤液进行加热、厌氧污泥接种等不同因素对生物反应器填埋场产甲烷的影响进行了研究.结果表明,回灌前对渗滤液进行加热、厌氧污泥接种都能加快生物反应器填埋场产甲烷的进程并加速填埋垃圾的稳定,而较低的渗滤液回灌频率有利于生物反应器填埋场快速进入产甲烷阶段,但不利于填埋垃圾的最终稳定.

The effects of the following factors(measures) on the generation of methane in bioreactor landfill were investigated through a simulation experiment. These factors(measures) are leachate recirculation rate, leachate heating before recirculation and microorganism inoculating by mixing sludge with solid waste. The research result shows that leachate heating before recirculation and microorganism inoculating by mixing sludge with the waste can quicken the generation of methane and accelerate the stabilization of solid waste, while a lower leachate recirculation rate is in favor of the generation of methane, but make against the stablilization of solid waste.
