摘　　要：化石燃料的消耗和有机废弃物的大量排放带来了严重的环境问题,而利用有机废弃物进行厌氧发酵制氢是可持续且环境友好的。为了克服单一底物厌氧发酵制氢存在的因营养元素不均衡、毒性抑制和微生物种类较少等导致氢气产率较低的局限性,不同类型的底物厌氧共发酵制氢技术得以开发,然而现阶段仍然存在过程机理不清楚和关键工艺参数不明确等问题。本文综述了有机废弃物厌氧共发酵制氢的必要性、优点及主要影响因素,归纳了不同有机废弃物混合比、有机负荷、发酵温度、水力停留时间、初始pH以及固液比、搅拌方式和反应器类型等关键工艺参数特征及其范围,分析比较了不同有机废弃物厌氧共发酵体系的氢气浓度及产率、发酵液pH、氨氮和挥发性脂肪酸及其组成等工艺特性,总结了产氢功能菌群及其产氢特性及不稳定系统特征微生物。随后指出了目前研究存在的一些不足,并对其在底物利用范围及其预处理、过程机理、技术完善及其综合评估等方面的研究与应用前景进行了展望,为有机废弃物厌氧共发酵制氢技术的研发与应用提供依据。The consumption of fossil fuel and the emission of organic wastes have brought serious environmental problems,and the reuse of organic wastes for anaerobic biohydrogen production is sustainable and environmentally friendly.To overcome the limitation of low biohydrogen production due to unbalanced nutritional elements,toxicity and fewer kinds of microorganisms in single substrate anaerobic fermentation,anaerobic co-fermentation biohydrogen production technology has been developed using different types of substrates.However,there are still some problems such as unclear process mechanism and uncertain key technical parameters.This paper summarizes the necessities,advantages and impact factors of biohydrogen production from organic wastes by anaerobic co-fermentation,reviews the characteristics and ranges of key process parameters such as mixing ratio of different organic wastes,organic loading rate,fermentation temperature,hydraulic retention time,initial pH value,solid-liquid ratio,stirring and reactor,analyzes the hydrogen concentration in biogas and its production rate,pH value in fermentation liquor,ammonia nitrogen and volatile fatty acid and their composition of anaerobic cofermentation systems with different organic wastes,and discusses the hydrogen-producing functional flora,its hydrogen-producing characteristics and the characteristics of unstable system microorganisms.Then the author points out some deficiencies in the current research,and finally puts forward the future research direction and application perspectives in the areas of substrate utilization and pretreatment,process mechanism,technology improvement and comprehensive evaluation.This review provides a basis for the research and application of biohydrogen production from organic wastes by anaerobic cofermentation technology.
