摘　　要：以木薯酒精废渣作为发酵原料,研究木薯酒精废渣在室温和中温条件下的产沼气潜力。结果表明,在室温(20℃)条件下发酵40 d,TS(总固体)、VS(挥发性固体)产沼气潜力分别为508.58和521.18 mL/g;在中温37℃条件下发酵33 d,TS、VS产沼气潜力分别为593.26和607.96 mL/g。这表明在中温条件下的沼气发酵效果较好,没有出现酸化现象,累计产气量比室温组多6 760 mL,产气速率增长较快,是一种良好的沼气发酵原料。应用厌氧消化处理木薯酒精废渣,不仅能减少废渣对环境的污染,而且能为木薯酒精废渣提供一种新的资源化利用途径。The biogas-producing potential of cassava alcohol waste were studied at room temperature and medium temperature.Cassava alcohol waste was used as the fermentation material to ferment for 40 days at room temperature(20℃).The results showed that the gas-producing potential of TS and VS was 508.58 and 521.18 mL/g,respectively.After fermentation at medium temperature of 37℃for 33 days,the gas-producing potential of TS and VS was 593.26 and 607.96 mL/g,respectively.The results showed that the biogas fermentation under medium temperature had a good effect,without acidification.The cumulative gas production in medium temperature group was 6760 mL more than that of the room temperature group,and the gas production rate increased rapidly.Therefore,cassava alcohol waste is a good raw material for biogas fermentation.Cassava alcohol waste was treated by using anaerobic digestion,which can not only reduce the pollution of waste residue to the environment,but also can provide a new resource utilization way for cassava alcohol waste.
