【摘要】：生物质暗发酵产氢不仅可以处理有机废物,同时可以获得清洁能源,实现了废物资源化利用。然而产氢种泥中大量耗氢菌的存在会导致暗发酵氢气产量低等问题,因此种泥预处理是暗发酵产氢的必需条件。随着暗发酵产氢基质的多样化,产氢种泥的预处理方法也不断发展。对近十年来产氢种泥预处理方法的发展进行了综述,并且结合发酵温度,讨论了种泥预处理方法和发酵温度两方面条件对暗发酵产氢的影响,并对该研究方向提出了展望,以期为后续暗发酵产氢的进一步研究提供参考。
[Abstract]:Hydrogen production by dark fermentation of biomass can not only treat organic waste, but also obtain clean energy. However, the presence of a large number of hydrogen consuming bacteria in the hydrogen-producing mud will lead to low hydrogen production in dark fermentation. Therefore, the pretreatment of seed mud is the necessary condition for hydrogen production by dark fermentation, and with the diversification of hydrogen production substrate in dark fermentation. The pretreatment methods of hydrogen-producing mud were also developed. The development of pretreatment methods of hydrogen-producing mud in recent ten years was reviewed and combined with fermentation temperature. The effects of pretreatment method of seed mud and fermentation temperature on hydrogen production by dark fermentation were discussed, and the research direction was prospected in order to provide a reference for further research on hydrogen production by dark fermentation.
