摘　　要：通过模拟实验研究了污泥接种、回灌前对渗滤液进行加热、不同的渗滤液回灌频率对生物反应器填埋场稳定进程的影响。研究表明,污泥接种、回灌前对渗滤液进行加热、较高的环境温度均有利于生物反应器填埋场快速稳定,垃圾填埋前期较低的渗滤液回灌频率有助于生物反应器填埋场快速进入产甲烷阶段,后期较高的渗滤液回灌频率则有利于填埋垃圾较快稳定。Through simulative experiments, such operation modes as microorganism inoculation, heating leachate before its recirculation, various leachate recirculation rate are compared and their influences on bioreactor landfill stabilization are studied. The results showed that microorganism inoculation, heating leachate before its recirculation, higher surroundings temperature assist in accelerating the stabilization of bioreactor landfill, and low leachate recirculation rate makes for fast methane generation in the earlier stage of landfill but against to stabilization of waste in the later stage.
