摘　　要：在我国,城市固体废弃物(MSW)多用厌氧填埋法处理,该方法有降解速度慢、气体不易控制等缺点。通过好氧填埋法与厌氧填埋法处理MSW的对比实验,得出利用好氧填埋处理MSW,使有机物降解率明显高于厌氧法。同时,根据垃圾场内部含氧量及湿度等因素将会影响好氧填埋效果,并在借鉴半好氧填埋技术的基础上,最终提出用分层通风来提高供氧效率,并与污水回灌等方法结合,不但解决垃圾场内部含水量不足问题,还能加快场内有机物的降解,使其迅速稳定。Anaerobic sanitary landfill is popular in disposing MSW(municipal solid waste) in China. But it has several disadvantages, such as slow degradation rate, difficulties in gas controlling, etc. This paper through anaerobic and aerobic contrasting experiments, elicits that organics degradation rate in aerobic landfill is better than in anaerobic landfill. At the same time, according to that several factors, such as oxygen content, humidity and so on, will influence aerobic effects, and based on the existing semiaerobic theory, the paper finally proposes the method of ventilation in different layers to enhance oxygen transportation rate and sewage recycling method, not only solves the water deficiency problem in landfill, but also expedites the organics' degradation, thus stabilize the landfill as soon as possible.
