摘  要：
采用批式发酵试验,秸秆与污泥分别经碱预处理后混合作为发酵底物,在起始pH为4.0、5.5、7.0、8.5、10.0和11.5下两相厌氧发酵,探讨不同起始pH值对混合发酵产氢产甲烷的影响。试验结果显示,不同起始pH值的氢气产率间具有显著差异性。在起始pH5.5时,得到最大氢气产率32.0mL·g-1-VS,产生的总能量为9.16kJ·g-1-VS。在起始pH11.5时,产生的总能量最高,为9.36kJ·g-1-VS。在产氢发酵阶段,微生物主要利用的是秸秆预处理后溶出的溶解性碳水化合物。两相厌氧发酵产氢产甲烷产生的能量,是单相厌氧发酵产甲烷产生能量的1.4～1.6倍。

摘  要：
Effects of different initial pH values(4.0, 5.5, 7.0, 8.5, 10.0 and 11.5)on co-production of hydrogen and methane from pretreated cornstalk and sewage sludge were investigated in batch experiments. Results showed significant differences among the hydrogen yields under different initial pH values. At initial pH of 5.5, the maximal hydrogen yield of 32.0 mL·g-1-VS was obtained, and the total energy produced was 9.16 kJ·g-1-VS. At initial pH of 11.5, the maximum methane yield of 265.7 mL·g-1-VS and maximum total energy of 9.36 kJ·g-1-VS were obtained. Hydrogen fermentation mainly consumed the soluble carbohydrates produced through pretreatment of cornstalk. Methane fermentation mainly utilized fatty acids produced in hydrogen fermentation stage. The total energy produced in the two-stage fer-mentation process was 1.4～1.6 times of that in the single-stage methane fermentation.
