摘　　要：以污水处理厂剩余污泥和生活垃圾为发酵原料,研究了不同原料配比对厌氧消化过程及消化效率的影响。结果表明,剩余污泥和生活垃圾联合厌氧发酵可以提高垃圾的消化效率,当剩余污泥和生活垃圾TS比为1∶4时厌氧消化效果最好,经过66 d消化后,COD去除率为59.79%,TS去除率为56.92%,VS去除率为66.87%。With excess sludge from wastewater treatment plant and kitchen waste as feedstock to the Joint Anaerobic Digestion, the effects of different ratio of raw materials on the anaerobic digestion process and digestion efficiency were investigated. The results showed that the joint anaerobic digestion of excess sludge and kitchen waste could improve the digestion efficiency, and the best digestion effect could be obtained when the TS ratio of excess sludge to kitchen waste was1∶4. After the digestion of 66 days, the degradation rates of COD, TS and VS could reach 59.79%,56.92% and 66.87% respectively.
