Energy generation was studied in a membraneless single‐chamber microbial fuel cell (SCMFC) with batch and continuous systems, using iron(III) as electron acceptor at the cathode and Shewanella putrefaciens as the biocatalyst. A maximum stable voltage of 0.769 V was achieved at a maximum tolerable concentration (MTC) of 50 ppm Fe for the batch mode of operation. A metal removal efficiency of 91.1 % and a total organic carbon removal of 85.5 % were obtained at the MTC. Also, the effects of various hydraulic retention times (HRT) were tested for the continuous process. A maximum voltage of 0.81 V was observed during operation for 13 h of HRT, along with a substrate degradation of 91.8 % and an iron removal of 86.4 %.

批量和连续单室微生物燃料电池的能量产生和铁去除

在具有间歇和连续系统的无膜单室微生物燃料电池（SCMFC）中，使用铁（III）作为阴极的电子受体，而腐臭希瓦氏菌（Shewanella putrefaciens）作为生物催化剂，研究了能量产生。对于批量操作模式，在50 ppm Fe的最大容许浓度（MTC）时，可实现0.769 V的最大稳定电压。在MTC处获得的金属去除效率为91.1％，总有机碳去除率为85.5％。此外，还针对连续过程测试了各种水力停留时间（HRT）的影响。在HRT运行13小时的过程中，观察到最大电压为0.81 V，同时基材降解为91.8％，铁去除率为86.4％。
