摘　　要：通过模拟生物反应器填埋场实验,就渗滤液回灌频率、回灌前对渗滤液进行加热、厌氧污泥接种等不同操作运行要素对生物反应器填埋场产气随时间变化的特性进行了研究。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的产气进程,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。Based on simulative experiments, the paper studies the change pattern with time of gas production properties of bioreactor landfill. The study is conducted by way of different operational modes, i.e. diffirent leaehate reeireulation rate, heating before leaehate reeireulation and inoculating anaerobic sludge. The simulative experiments showed that heating before leaehate reeireulation and inoculating anaerobic sludge can both speed up gas production, while lower leaehate reeireulation rate helps the bioreaetor landfill reach the stage of methane production quickly but fails to facilitate the landfill＇ s final stabilization.
