摘　　要：根据城市生活垃圾的特点和性质,利用物料平衡和热力学原理进行好氧堆肥实验装置的设计,并对堆肥发酵仓容积的确定和配套辅助设备进行了研究,得出当堆肥装置直径小于225m时,需采取保温措施。通过强制通风静态仓式堆肥小试实验进行的城市生活垃圾堆肥结果表明,通过30℃及以上的水浴加热,可实现固体废物的堆肥化。According to the characteristics of domestic waste,an aerobic-composting equipment was designed using mass balance and thermodynamics principle,and a study was done on how to determine the volume of the storehouse and aided equipment.It was concluded that when the diameter of composting system was less than 2.25 m,heat preservation should be carried out. Domestic waste composting was tested with the bench scale aerated static bin and the experimental results proved that the equipment realized the composting of solid waste when it was heated up in more than 30 ℃water bath.
