Abstract

Microbial fuel cell (MFC) is an attractive renewable and sustainable technology to meet up the drastic energy crisis of the world through waste water treatment. This Bioelectrochemical system (BES) converts biomass spontaneously into electricity by the metabolic activity of microorganisms. Food processing industry generally discharges large volume of wastewater, which creates adverse financial and ecological impacts to the industry and environment. In this present contribution, electricity production from food processing industry wastewater that serves as substrates in MFCs was investigated. Dual chambered mediator-less MFC was designed and fabricated using locally available materials. Performance of the MFC was evaluated by measuring potential parameters, such as current generation, current density, change in pH, and change in chemical oxygen demand at different operating conditions. Polarization experiments were conducted to find the maximum power density. Current generation increased with increasing sludge loading, and maximum results were recorded as 90 µA with 9 g of sludge and optimum pH value 8 in the anode chamber. This study documented a maximum power density of 7.42 mW/m 2 with the corresponding current density of 25 mA/m 2 . Citation: Amin, M. S. A., Talukder, M. J., Raju, R. R., and Khan, M. M. R. (2019).

食品加工废弃物转化为生物能源:孟加拉国视角

微生物燃料电池(MFC)是一种有吸引力的可再生和可持续发展的技术，通过处理废水来应对世界上日益严重的能源危机。这种生物电化学系统(BES)通过微生物的代谢活动将生物质自发地转化为电能。食品加工业通常排放大量废水，这对工业和环境造成了不利的经济和生态影响。在目前的贡献中，研究了作为mfc底物的食品加工工业废水的电力生产。双室无介质MFC设计和制造使用当地可用的材料。通过测量不同操作条件下的电流产生、电流密度、pH变化和化学需氧量变化等电位参数来评价MFC的性能。通过极化实验确定了最大功率密度。随着污泥负荷的增加，电流增加，最大结果为90µA，污泥量为9 g，阳极室的最佳pH值为8。该研究记录的最大功率密度为7.42 mW/ m2，相应的电流密度为25 mA/ m2。引用本文:Amin, m.s.a.， Talukder, m.j.， Raju, r.r.， and Khan, m.m.r.(2019)。食品加工废弃物转化为生物能源:孟加拉国视角。可再生能源发展趋势，5(1)，1-11。DOI: 10.17737 / tre.2019.5.1.0080
