摘　　要：以中国木薯和老挝木薯发酵产乙醇后剩余的干酒糟为原料,在(35±1)℃条件下进行批量式沼气发酵试验,发酵料液的TS质量分数为4%。结果表明,中国木薯废醪渣和老挝木薯废醪渣的平均日产气量分别为158.2、149.3 mL/d。中国木薯醪渣的TS产气率和VS产气率分别为659、867 mL/g,老挝木薯醪渣的TS产气率和VS产气率分别为799、1 080 mL/g,沼气中的平均甲烷含量分别为50%和51%左右。It uses the dried distiller’s grains remaining after the fermentation of Chinese cassava and Lao cassava to produce alcohol. The batch biogas fermentation experiment is carried out under the condition of(35±1) ℃. The concentration is 4%.The experimental results show that the average daily gas production of Chinese cassava distiller’s grains and Lao cassava distiller’s grains is 158.2,149.3 mL/d, respectively. The TS gas production rate and VS gas production rate of Chinese cassava distillers’ grains were 659,867 mL/g, respectively. The TS gas production rate and VS gas production rate of Laos cassava distiller’s grains are 799,1 080 mL/g, respectively. The average methane content in biogas was 50% and 51%, respectively.
