A novel two-chamber microbial fuel cell (MFC) operation with a continuous anaerobic-aerobic decolorization system was developed to improve the degradation of the triphenylmethane dye, Victoria blue R (VBR). In addition, bioelectricity was generated during the VBR degradation process, and the operation parameters were optimized. The results indicated that the VBR removal efficiency and electricity generation were affected by the VBR concentration, liquid retention time (LRT), external resistance, gas retention time (GRT), and shock loading. The optimal operation parameters were as follows: VBR concentration, 600 mg L; LRT, 24 h; external resistance, 3300 Ω; and GRT, 60 s. Under these operating conditions, the VBR removal efficiency, COD removal efficiency, and power density were 98.2% ± 0.3%, 97.6% ± 0.5%, and 30.6 ± 0.4 mW m, respectively. According to our review of the relevant literature, this is the first paper to analyze the electrical characteristics of a continuous two-chamber MFC operation and demonstrate the feasibility of the simultaneous electricity generation and decolorization of VBR.
开发了一种新型双室微生物燃料电池（MFC）与连续厌氧-好氧脱色系统联用的运行方式，以提高三苯甲烷染料维多利亚蓝R（VBR）的降解效果。此外，在VBR降解过程中产生了生物电，并对运行参数进行了优化。结果表明，VBR去除效率和发电受到VBR浓度、液体停留时间（LRT）、外电阻、气体停留时间（GRT）和冲击负荷的影响。最佳运行参数如下：VBR浓度600 mg/L；LRT 24 h；外电阻3300 Ω；GRT 60 s。在这些运行条件下，VBR去除效率、化学需氧量（COD）去除效率和功率密度分别为98.2%±0.3%、97.6%±0.5%和30.6±0.4 mW/m²。根据我们对相关文献的检索，这是第一篇分析连续双室MFC运行的电学特性并证明VBR同步发电和脱色可行性的论文。
