摘　　要：以生活垃圾为研究对象,设置厌氧、好氧、微好氧3组填埋反应器,对填埋过程中渗滤液、垃圾堆体、填埋气三相指标进行分析,研究填埋垃圾的稳定化进程。结果表明:好氧和微好氧环境下能够减少渗滤液的产生量,加速渗滤液中污染物的降解。相对于厌氧填埋反应器,好氧填埋反应器温度更高,垃圾堆体沉降速度更快。微好氧填埋过程中垃圾堆体内部O_(2)浓度可以维持在10%左右,O_(2)浓度分布由上至下依次递减,随着填埋深度的增加,气体更难扩散。The solid waste was taken as research object.Three groups of anaerobic,aerobic and micro-aerobic landfill reactors were set up to analyze the three phase indexes of leachate,landfill waste,and landfill gas in landfill process,so as to study the stabilization process of landfill.The experimental results showed that the aerobic and micro-aerobic conditions could reduce the production of leachate and accelerate the degradation of pollutants in leachate.Compared with anaerobic landfill,the aerobic landfill reactor temperature was higher and the settlement rate of the waste pile was faster.In the process of micro-aerobic landfill,the concentration of O_(2) inside the landfill could be maintained at about 10%.The concentration distribution of O_(2) decreased from top to bottom.As the depth of the landfill increased,it became harder for the gas to disperse.
