在37℃条件下对不同比例的牛粪和厨余垃圾进行为期50d的联合厌氧消化试验.结果表明:(1)牛粪与厨余垃圾质量比2/1和1/2联合厌氧消化的实际产气潜能为0.66和0.71L·g-1(以挥发性固体VS质量计),比加权计算值分别提高50%和29%;(2)4种比例物料的甲烷平均浓度约为50%～55%,其生物能范围为18.92～20.81MJ·m-3;(3)在联合厌氧消化过程中,牛粪和厨余垃圾质量比1/2物料的产气效率最高,反应前10d的产气量占总产气量的55.4%,前20d产气量占总产气量的92.2%;(4)纯牛粪、牛粪和厨余垃圾质量比2/1、牛粪和厨余垃圾质量比1/2及纯厨余垃圾4种比例物料厌氧消化的最终生物降解率分别为46.99%、53.31%、70.12%和66.25%.
