| 摘 要： | 利用分离的小球藻(Chlorella vulgaris)构建了光合微生物燃料电池，考察了小球藻加入阴阳极和以废水为底物的电池产电性能及机理. 结果表明，构建的微生物燃料电池是可行的，电能输出主要依赖吸附在电极表面的藻，而与悬浮在溶液中的藻基本无关. 光照是该燃料电池电压变化的主要影响因素之一. 在阴极室中添加铁离子，通过其二和三价间的循环转化，提高电子的传递速率，加快质子和氧气的反应，电池的输出功率密度达到11.82 mW/m2，COD去除率达到40%. 这种电池将化学能、光能转化为电能的同时可处理污水并回收小球藻.

| Abstract: | The photosynthesis microbial fuel cell was constructed using separated Chlorella vulgaris.Electricity production and mechanism of the cell were preliminarily studied.By analyzing the cell voltage measured by the acquisition system, it was proved that the photosynthetic microbial fuel cell was feasible.Microbial electricity generation was mainly attributed to the electrochemically and biologically active cells attached to the electrode, and the suspended algae in the solution were not involved.The illuminati... |
