摘　　要：对分类收集于城市生活的有机垃圾作为沼气发酵原料的相关参数与特性进行了研究。结果显示:来自相对固定区域的城市生活有机垃圾,其总体TS(总固体)、VS(挥发性固体)、COD含量相对较为稳定,在连续8个月的监测中,其含量的平均值分别为:10.17％、4.64％和8.17％;生活有机垃圾作为整体,在兼氧沤解预处理条件下常温发酵,每公斤TS具有0.389m3或每公斤COD具有0.499m3的产气潜力,产气特性表现为,投料2d后进入产气高潮,20d时产气量达总产气量的90％以上。Study on the parameters and characteristics which affecting anaerobic digestion to produce biogas using organic fractions of MSW as substrate have been conducted. It was found that, when the municipal domestic organic refuse came from relatively fixed area, its average contents of TS, VS, COD only slightly changed, with the average contents of TS, VS, COD resulted from longterm monitoring were 10.17%, 4.64%, 8.17% respectively. The biogas production potential of 0.389m3/kgTS or 0.499m3/kgCOD for this type of organic wastes was obtained. The biogas production reached its flush season after 2 days, anaerobic digestion and the accumulated biogas volume generated in the first 20 days occupied 90% of the possible biogas quantity that the wastes were able to generate.
