摘要： 在这项研究中，以实际生产的薯片加工废水为原料，研制了双室微生物燃料电池（MFC）生物传感器。从电流测量范围、毒性检测和灵敏度、操作稳定性等方面评价了基于MFC的生物传感器的性能。结果表明，MFC可以简单地转化为在线生物传感器单元，检测实际PCPW中悬浮物和酸性物质对阳极附着生物膜的有害影响以及产生的电流值。观察到电流值显著降低，表明输入生物传感器单元的PCPW中有害物质的不利影响。结果表明，有害组分与有利底物在结合氧化还原复合物时存在竞争。通过IKm模型的测定系数(R2)和均方误差值分别为0.927和0.363，实验结果与预测结果之间获得了良好的拟合。此外，还提出了一种基于直接测量实际现场数据的新方法，以取代传统的统计方法。

Abstract: In this study, a dual-chamber microbial fuel cell (MFC) fed with actual potato chips’ processing wastewater (PCPW) was tested as a biosensor. The performance of MFC-based biosensor was evaluated in terms of the current measurement range, toxicity detection and sensitivity, and the operational stability. The results revealed that the MFC can simply be converted to an online biosensor unit to detect the harmful effect of suspended solids and acidic content in the actual PCPW on the anodic attached biofilm and the values of the generated current as well. A notable decrease in the current values was observed indicating the adverse effects of the harmful matters in the PCPW fed to the biosensor unit. The results proposed a competition between the harmful components and the favorable substrate in binding to the redox complex. An excellent fitting was obtained between the experimental and predicted results by IKm model with determination coefficient (R2) and mean-square-error values of 0.927 and 0.363, respectively. Additionally, a new approach was developed based on direct measurement of actual field data to replace the conventional statistical methods.
