| 中文摘要 |
| 在批式培养实验中以有机废弃物为原料,通过厌氧生物发酵制备生物氢气研究了菌种来源、有机废弃物种类对产氢能力的影响,以及生物氢发酵过程中液相组成的变化以活性污泥为菌种来源,以淀粉为底物,在30L改进的UASB反应器中进行了放大实验,生物气中氢气浓度达40%～51%,CO2浓度为49%～60%,且没有检测到甲烷气体,生物气经碱液吸收后氢气纯度大于97%持续产氢时间超过120d. |
| 英文摘要 |
| Biological hydrogen production is a process of applying anaerobic biological fermentation method to produce hydrogen from organic wastes. Hydrogen production potential of different microbiological source and organic wastes, as well as the composition of fermentation product in liquid phase, were studied in the batch culture experiments. Magnifying experiment of biohydrogen production was carried out in 30L improvement UASB reactor using anaerobic fermentation of artificial wastewater containing starch by activated sludge process. The experiment confirm that hydrogen and carbon dioxide percentage of biogas were 40%～51% and 49%～60% under the condition of hydrogen production process (pH was 4.5～5.5 sludge VSS was 10g/L; starch COD was 5000mg/L), and no methane was observed. Hydrogen purity was more than 97% by an absorption of sodium hydrate solution , continuous hydrogen production was more than 120 days. |
