有机废物规模化产氢关键科学问题及其研究进展

摘要

利用有机废物生物产氢具有反应条件温和、可实现废物资源化及可持续发展等优点，是世界各国竞相开发的高新技术。但目前生物产氢效率低，达不到低成本、规模化的生产水平。本文从生物产氢的过程、基质、接种物及反应器等方面出发，论述了目前国内外生物产氢的研究进展，提出规模化生物产氢系统构建过程亟待解决的关键问题。%Bio-hydrogen production by using organic waste is the advanced technology people are racing to develop,which has the advantages of mild reaction conditions,waste recycling and sustainable development. However,at present the efficiency of bio-hydrogen production is pretty low and it can't reach the production levels with low cost and large scale. This paper will start from the process of bio-hydrogen production,the substrate,inoculum and the reactorto discuss the research progress of bio-hydrogen production at home and abroad nowadays,come up with the key problems that need to be addressed in the process of system building of scale hydrogen production.
