Finding sustainable alternative energy resources and treating wastewater are the two most important issues that need to be solved. Microbial fuel cell (MFC) technology has demonstrated a tremendous potential in bioelectricity generation with wastewater treatment. Since wastewater can be used as a source of electrolyte for the MFC, the salient point of this study was to investigate the effect of pH on bioelectricity production using various biomass feed (wastewater and river water) as the anolyte in a dual-chambered MFC. Maximum extents of power density (1459.02 mW·m⁻²), current density (1288.9 mA·m⁻²), and voltage (1132 mV) were obtained at pH 8 by using Bhairab river water as a feedstock in the MFC. A substantial extent of chemical oxygen demand (COD) removal (94%) as well as coulombic efficiency (41.7%) was also achieved in the same chamber at pH 8. The overall performance of the MFC, in terms of bioelectricity generation, COD removal, and coulombic efficiency, indicates a plausible utilization of the MFC for wastewater treatment as well as bioelectricity production.

阳极电解液 pH 值对使用不同生物质进料的双室微生物燃料电池性能的影响

寻找可持续的替代能源和处理废水是需要解决的两个最重要的问题。微生物燃料电池 (MFC) 技术在废水处理生物发电方面显示出巨大的潜力。由于废水可用作 MFC 的电解质来源，因此本研究的重点是研究 pH 值对使用各种生物质进料（废水和河水）作为双室 MFC 阳极电解液的生物发电的影响。最大功率密度 (1459.02 mW·m ^-2 )、电流密度 (1288.9 mA·m ^-2) 和电压 (1132 mV) 在 pH 值为 8 时通过使用 Bhairab 河水作为 MFC 中的原料获得。在 pH 8 的同一室中也实现了相当程度的化学需氧量 (COD) 去除 (94%) 和库仑效率 (41.7%)。 MFC 的整体性能，在生物发电、COD 去除方面和库仑效率表明 MFC 可用于废水处理和生物发电。
