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。
Dark fermentative hydrogen production from the biomass resources can not only treat the organic wastes, but also recover the clean energy to achieve the resource utilization of wastes. However, there are a great amount of hydrogen consuming microorganisms in the seed sludge of dark fermentative hydrogen production system, which reduces the hydrogen yield obviously. Therefore, pretreatment of seed sludge is necessary to enrich hydrogen producing microorganisms for a hydrogen fermentation process. As the variation of substrates used for hydrogen fermentation, pretreatment methods of hydrogen producing seed sludge have also been developed continuously. The research development of hydrogen producing seed sludge pretreatment in the recent decade was reviewed, and the effects of seed sludge pretreatment methods and fermentation temperature on hydrogen fermentation were discussed. Outlook suggestions were also proposed for this study field to provide reference for further related study.
