中文摘要：

采用好氧活性污泥为种泥,以连续流搅拌槽式反应器(CSTR)作为发酵生物制氢反应装置,对发酵法生物制氢系统的启动和运行进行了实验研究。反应器有效容积为10L,接种污泥取自哈尔滨啤酒厂有机废水好氧生物处理系统的二沉池。反应器在污泥接种量为6.09 g·L~(-1),进水有机物浓度2000 mg COD·L~(-1),pH 5～7,HRT 8 h和(35±1)℃的条件下启动,运行27 d后达到稳定的乙醇型发酵状态,最高产气速率和产氢速率分别达到10.1 L·d~(-1)和5.8 L·d~(-1)。在进水有机物浓度提高到4000 mg COD·L~(-1),其他控制条件不变的情况下,系统可在3 d内重新达到新的平衡,最高产气速率和产氢速率分别达到20.7 L·d~(-1)和10.8 L·d~(-1),而氢气含量和发酵类型未发生改变。

英文摘要：

Biohydrogen production from diluted molasses by activated sludge was investigated in a continuous stirred-tank reactor(CSTR) under condition of continuous flow in this paper. The reactor, with a working volume of 10 L, was inoculated by anaerobic activated sludge from a local organic wastewater treatment process. The reactor started up under the condition of influent COD concentration 2000 mg·L~(-1), pH 5～7, HRT 8h and (35±1)℃, with a biomass of 6.09g·L~(-1)activated sludge in term of volatile suspended sol...
