摘　　要：以5种典型农业废弃物(猪粪、鸡粪、秸秆、餐饮垃圾和厨余垃圾)为研究对象,采用干式厌氧发酵产氢技术,研究不同初始pH、温度对产氢潜力和代谢途径的影响。结果表明,当中温、初始pH为7.0时,餐饮垃圾产氢效果最佳,最大累积产氢量为261.96mL,最大产氢速率为15.18mL/h,氢气体积分数最大值为64.61%;当中温、初始pH为6.0时,秸秆产氢效果最好,最大累积产氢量为254.41mL,最大产氢速率为24.50mL/h,氢气体积分数最大值为65.54%。5种农业废弃物干式厌氧发酵产氢的代谢途径均以丁酸型发酵为主。Five kinds of agricultural wastes(pig manure,chicken manure,straw,food wastes and kitchen wastes)were used for hydrogen production during the dry anaerobic fermentation.The effects of hydrogen potential and metabolic pathways under different initial pH and temperatures were investigated.The results showed that the best hydrogen production using food wastes was obtained under the initial pH of 7.0 in the mesophilic temperature.The maximum accumulative hydrogen production,production rate and hydrogen volume proportion were 261.96 mL,15.18 mL/h and 64.61%,respectively.The best hydrogen production using straw was obtained under the initial pH of6.0 in the mesophilic temperature.The maximum accumulative hydrogen production,production rate and hydrogen volume proportion were 254.41 mL,24.50 mL/h and 65.54%,respectively.The main metabolic pathway of hydrogen production was butyric acid fermentation via the dry anaerobic fermentation using five agricultural wastes.
