摘要
通过模拟实验,研究了渗滤液回灌前加热、加入厌氧污泥进行微生物接种、变化渗滤液回灌频率等操作运行方式对生物反应器填埋场渗滤液特征的影响。结果表明,回灌前对渗滤液进行加热、加入污泥进行微生物接种有利于生物反应器填埋场渗滤液有机污染物浓度的快速下降;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。
Through simulative experiment,operation modes such as heating leachate before its recirculation,having a microorganism inoculation,adopting various leachate recirculation rate are compared and their influences on the character of bioreactor landfill leachate are studied.It is shown that leachate heating before its recirculation and microorganism inoculation assist in quickening the decline of leachate COD concentration in bioreactor landfill,while low leachate recirculation rate makes for fast generating methane.
