In this study, a dual chambered microbial fuel cell (MFC) was fabricated for the treatment of tannery wastewater with concurrent production of bio-energy. The tannery effluent acts as an anolyte and a synthetic electrolytic solution as the catholyte. Five electrochemically active bacteria from the biofilm were isolated that showed homology with Klebsiella quasipneumoniae, Klebsiella pneumoniae, Cloacibacterium normanese, Bacillus firmus and Pseudomonas reactans, using 16S rDNA analysis. The physiochemical studies of treated wastewater showcased the 88%, 74% and 94% reduction in COD, BOD and TDS level, respectively. The maximum voltage output and power density obtained using electroactive consortium in MFC was 940 mV and 7371 mW/cm, respectively. The techno-economic feasibility of the bio-electrochemical system was studied for future bioprospecting. The present study reports a significant power generation with simultaneous effluent treatment up to a maximum of ∼85%, in a sustainable and eco-friendly manner.
在这项研究中，构建了一个双室微生物燃料电池（MFC），用于处理制革废水并同时生产生物能源。制革废水作为阳极电解液，而合成电解液则作为阴极电解液。从生物膜中分离出 5 种电化学活性细菌，通过 16S rDNA 分析，这些细菌与肺炎克雷伯菌、肺炎克雷伯菌、直肠弯曲杆菌、坚固芽孢杆菌和反硝化假单胞菌具有同源性。处理后废水的理化研究表明，COD、BOD 和 TDS 水平分别降低了 88%、74%和 94%。在 MFC 中使用电活性联合体获得的最大电压输出和功率密度分别为 940 mV 和 7371 mW/cm。对生物电化学系统的技术经济可行性进行了研究，为未来的生物勘探提供了依据。本研究报告了一种以可持续和环保的方式，在最大程度上达到约 85%的高效发电和同时处理废水的方法。
