摘　　要：以苹果渣为对象,进行固态厌氧发酵制备氢气的技术研究。考察了产氢菌的富集方式、苹果渣预处理条件、厌氧发酵条件对苹果渣产氢效果的影响。研究结果表明,产氢菌的最佳富集方法为:活性污泥在室温(25℃)和pH11.0条件下预处理1.5h,然后调整pH为7.0。苹果渣粉碎至2000μm,在浓度为1%的NaOH溶液中浸泡2h后,调整pH至中性;苹果渣(w):麸皮(w):水(w)=4:1:25,在此条件下,苹果渣最大产氢量为16.47mL/gTS(TS:totalsolid)。表明苹果渣在固态条件下具有发酵生物质气体的潜力。Biohydrogen was produced from apple residue through solid-state anaerobic fermentation. Influences of pretreatment conditions of natural sludge and apple residue and ferment conditions on the biehydrogen production from apple residue were studied. Results indicated that the maximum hydrogen yield of 16.47mL/gTS was obtained under the condition of pill 1 pretreating natural sludge for 1.5h,apple residue was soaked by 1% NaOH for 2h after been comminuted at 2000μm granularity,apple residue：bran：water at 4：1：25. It was showed that biohydrogen by solid-state anaerebic fermentation had great poteniial for development.
