Abstract: 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 O2 inside the landfill could be maintained at about 10%. The concentration distribution of O2 decreased from top to bottom. As the depth of the landfill increased, it became harder for the gas to disperse.
