In this study, a single chamber microbial fuel cell (SCMFC) with nano-polypyrrole modified graphite felt as anode- and platinum-coated carbon cloth as cathode was employed to reduce the amount of copper, Cu²⁺, in synthetic wastewater. The performance of the SCMFC was studied for two inocula, Shewanella putrefaciens and mixed culture. Maximum tolerable concentrations of 50 mg/L and 70 mg/L of copper and power densities of 0.33 W/m² and 0.304 W/m² were achieved, respectively, for the pure and mixed cultures. The study shows that microbial tolerance level towards the toxicity of metal strongly influences the MFC performance and the pure culture showed better performance than mixed culture over the Cu toxicity. This study exhibits the possibility of using single chamber microbial fuel cell for treating wastewater containing copper.

在这项研究中，以纳米聚吡咯改性的石墨毡为阳极，涂铂的碳布为阴极的单室微生物燃料电池（SCMFC）用于减少合成废水中的铜Cu ^2+含量。研究了SCMFC在两种接种物-腐烂希瓦氏菌和混合培养物中的性能。铜的最大容许浓度为50 mg / L和70 mg / L，功率密度为0.33 W / m ²和0.304 W / m ²分别针对纯培养和混合培养获得了成功。研究表明，微生物对金属毒性的耐受性水平强烈影响MFC的性能，并且纯培养物比混合培养物对Cu的毒性更好。这项研究展示了使用单室微生物燃料电池处理含铜废水的可能性。
