微生物燃料电池（MFC）是一种将有机和无机底物的化学能直接转化为电能的新型技术。化石燃料的使用和最近的能源危机使人们越来越关注这项技术。除了发电，废水处理是MFC的另一个应用。硫化物是废物中常见的有害离子。在这篇文章中，制造了双室MFC，并在厌氧阳极室中使用微生物的混合培养物作为活性生物催化剂将底物转化为电能。实验结果表明，该MFC可以成功地将硫化物转化为单质硫并进行发电。废水中硫化物的初始浓度为1.5g L-1，MFC运行10天后将其去除。最大产生功率和电流密度分别为48.68 mW·m-2和231.47 mA·m-2。此外，研究了生物阴极的影响，因此获得的功率和电流密度数据分别增加到372.27 mW·m-2和1，665.15 mA·m-2。
Microbial fuel cell (MFC) is a novel technology that is able to convert the chemical energy of organic and inorganic substrates to electrical energy directly. The use of fossil fuels and recent energy crisis bring increasing attention to this technology. Besides electricity generation, wastewater treatment is another application of MFCs. Sulfide is a hazardous ion that is common in wastes. In this article, dual‐chamber MFC was fabricated and a mixed culture of microorganisms was used as an active biocatalyst in an anaerobic anodic chamber to convert substrate to electricity. The obtained experimental results indicate that this MFC can successfully alter sulfide to elementary sulfur and power generation. The initial concentration of sulfide in wastewater was 1.5 g L−1, and it was removed after 10 days of MFC operation. Maximum produced power and current density were 48.68 mW⋅m−2 and 231.47 mA⋅m−2, respectively. Besides, the influences of a biocathode were investigated and accordingly the data obtained for power and current density were increased to 372.27 mW⋅m−2 and 1,665.15 mA⋅m−2, respectively.
