英文摘要： The organic acid accumulation and the generated product of dark fermentation effluent restrict hydrogen production microbial metabolic activity which is not conducive to photosynthetic bacteria decomposing and utilizing dark fermentation effluent. As a result, dark fermentation effluent inhibits hydrogen production. So the quality control and the mass transfer of dark fermentation effluent become a key point to affect hydrogen production efficiency, and researching it has important scientific significance and practical application value. Forming regularity, coexistence conditions and competition mechanism of straw biomass dark fermentation effluent are studied by experiments, theoretical analysis and mathematical simulation. In order to solve the inhibition of dark fermented effluent on hydrogen production, mass transfer characteristics and quality control mechanism are researched to discover the efficient mass transfer theory and the optimal energy conversion theory of dark fermented effluent and obtain the relationship between quality control and mass transfer, and a high efficiency, energy saving, low cost of dark fermented effluent quality control system will be established. The achievements of this project will contribute theoretical foundation to improve bio-hydrogen production efficiency and realize the industrial application of bio-hydrogen production quality control system.
