摘  要：
分别按餐厨废弃物、牛粪和秸秆挥发性固体(VS)比例为0:2:1、0.4:1.6:1、0.8:1.2:1、1.2:0.8:1、1.6:0.4:1、2:0:1混合形成6个试验组,各组总固体浓度(TS)均为17%,在中温(35±1)℃条件下进行厌氧发酵试验,试验进行48 d。结果表明,物料混合比例对消化效果有显著影响,VS比例为0.4:1.6:1时产气效果最佳,最高容积产气率为989 m L·L-1·d-1,产气稳定后甲烷平均含量为55.6%。随着餐厨比例增加,系统稳定性变差,当VS比例为1.2:0.8:1时,反应器中有丙酸抑制现象。当VS比例为1.6:0.4:1和2:0:1时发生酸败。

摘  要：
The mixing ratioes of kitchen waste, cattle manure and maize straw VS ratio were 0:2:1,0.4:1.6:1, 0.8:1.2:1, 1.2:0.8:1, 1.6:0.4:1 and 2:0:1. The test lasted 48 d which TS was 17% in(35±1)℃.The largest volumetric gas production rate was 989 mL · L-1· d-1, and the average content of methane was55.6%. According to the stability of the system, gas production rate and the methane production rate, the optimal ratio of kitchen waste, cattle manure and maize straw which was 0.4:1.6:1 was determined. The greater the proportion of kitchenware, the worse the stability of the system. When the kitchen waste, cattle manure and maize straw VS ratio was 1.2:0.8:1, the phenomenon of proponic acid inhibition was found.when the kitchen waste, cattle manure and maize straw VS ratio was 1.6:0.4:1 and 2:0:1. rancidity phenomenon was found.
