连续制氢反应器中光合细菌特性试验研究

摘要

[Objective] The study was to lay a foundation for the industrialization development of hydrogen production with photosynthetic bacteria. [Method] With the mixed bacteria of photosynthetic bacteria as the tested strains, the concentration change, hydrogen producing characteristics of the photosynthetic bacteria and the relationship between bacteria number and hydrogen yield were studied. [ Result] The photosynthetic bacteria concentration and hydrogen yield in the 2#, 3# compartment of continuously hydrogen production reactor was the most. In the same compartment, the photosynthetic bacteria concentration and hydrogen yield on the 2nd, 3rd d was the most. [Conclusion] The hydrogen yield of photosynthetic bacteria in reactor was reduced with the reduction of its concentration.%[目的]为光合细菌制氢的工业化发展奠定基础.[方法]以光合细菌混合菌群为试验菌种,研究其在连续制氢反应器中的浓度变化、产氢特性及细菌数量与产氢量的关系.[结果]连续制氢反应器的2#、3#隔室光合细菌浓度最大,产氢量也最大.同一隔室内,第2、3d光合细菌浓度和产氢量均达到最大.[结论]产氢量随反应器中光合细菌数量的减少而减少.
