摘　　要：在25℃和35℃的条件下,以醋糟为发酵原料,进行批式干发酵产沼气试验。研究了温度对醋糟干发酵产沼气的影响,并分析了醋糟干发酵的可行性。结果表明,在发酵浓度TS为23.7%的条件下,35℃的原料产气率比25℃提高了24.3%,池容产气率提高21.4%。试验表明,醋糟是良好的干发酵产沼气的原料,宜采用的干发酵温度为35℃。A batch biogas fermentation device was used to study the influence of temperature on dry anaerobic fermentation of vinegar residue under different temperatures （25℃, 35℃ ）. The feasibility of dry fermentation using vinegar residue as raw material is analyzed. The results showed that, under the initial total solid （TS） of 23.7%, the performance at 35℃ was better, with biogas production potential increased by 24.3% comparing with that under 25℃, and volumetric biogas production rate increased by 21.4%. These showed that vinegar residue was suitable material for dry anaerobic fermenta- tion, and optimal temperature was 35℃.
