摘　　要：城市生活垃圾处理已成为现代化大型城市的一种极大的威胁。我国城市生活垃圾的无害化方法主要有卫生填埋法、焚烧法、堆肥法和资源化综合处理法。本文探讨了垃圾微波裂解处理工艺,确定了最佳氮气流量0.2 m3/h;垃圾停留时间t=2.63 h、预热时间t1=1.25 h、分解时间t2=1.48 h;350℃时垃圾开始裂解;554℃裂解结束;裂解反应过程平稳。Dealing with the household garbage became a great threat to the large modern cities. In China, some kinds of solutions such as： sanitary landfill, incineration, composting, and integrated treatment for the The microwave pyrolysis for the garbage was explored, and the best nitrogen flow rate was 0.2 m3/h, residence garbage was 2.63 h, warm - up time was 1.25 h, and the decomposition time was 1.48 h. At 350℃, the cracking, and at 554℃, the course of cracking ended. The process of pyrolysis reaction was steady.
