摘　　要：在批式和小试实验的基础上,以牛粪堆肥作为菌种来源,以玉米秸秆作为发酵底物,进行了5L和30L规模的产氢对比实验,对玉米秸秆厌氧发酵制氢的影响因素及变化规律进行了研究。结果表明,前期小试实验条件在放大试验产氢过程中能够取得很好的产氢效果,影响因素的变化也有类似的规律性。其中主要影响因素为温度、pH、底物浓度、底物停留时间、搅拌转速以及溶液中的微量营养元素-重金属离子等,最适宜的温度为37℃,最佳pH为5.0～5.2。Taking cornstalks as substrate, the experiment of batch anaerobic digestion of biohydrogen production by dairy manure compost is studied in 5 L and 30L reactors. The effects and rules of fermentative hydrogen production from cornstalks are studied. The results show that it can produce more hydrogen in the scale-up experiment, and the change of factors also has the similar regularity in the effects. There are some major factors that influence it such as materiel concentration,hydraulic retention time, agitation speed as well as micronutrient-heavy metal ion, and so on. The most appropriate temperature is 37℃ ,and pH for it is 5. 0 -5.2.
