反应器类型对生物厌氧发酵产氢的影响研究进展

利用有机废水或废弃物厌氧发酵制取氢气可以同时达到除废和产能的双重目的,是近年来生物质能的研究热点。产氢反应器的类型会影响反应器内产氢菌的数量和种类以及微生物与底物之间的传质作用,进而影响产氢系统的稳定性和产氢效果。对厌氧产氢悬浮细胞系统和固定化细胞系统（颗粒污泥、生物膜、微生物包埋体）保留生物量的效果进行了对比,总结了连续搅拌釜式反应器（CSTR）、厌氧序批反应器（ASBR）、上流式厌氧污泥床（UASB）、膨胀颗粒污泥床（EGSB）、厌氧填充床、厌氧流化床（AFBR）以及复合生物反应器等不同反应器类型对厌氧产氢的影响,并提出了一些建议与展望,以期为以后的研究提供指导作用。

Progress in Studying Effects of Bio-reactor Type on Anaerobic Fermentative Bio-hydgrogen Production

Recently,fermentative hydrogen production with organic wastewater or waste becomes a research focus in the field of bio-energy production,for it is a good way of garbage disposal and energy production.The type of bio-reactor is considered to have important effects on both microbial community structures and mass transfer efficiency between biomass and substrates,which could influence the hydrogen production and stability of the process.In this paper,immobilized-and suspended-cell H2-producing systems are compared based on biomass growth in forms of granular,bio-film,gel-entrapped bio-particle.Reactor configurations such as continuous stirred tank reactor,anaerobic sequencing batch reactor,up-flow anaerobic sludge blanket,expanded granular sludge bed,anaerobic packed bed,anaerobic fluidized-bed,hybrid bio-reactor and their impacts on bio-hydrogen production are summarized.Finally,suggestions and perspectives are proposed to provide guidance for further research.
