构建了以单过硫酸钾（PMS）为阴极电子受体的双室微生物燃料电池（Microbial fuel cell，MFC），考察了MFC启动过程中同步除污产电性能以及阳极微生物群落的变化特性。结果表明，外接电阻为1 000 Ω以及PMS浓度为10 mmol/L的情况下，MFC在1个月内快速启动，其最大输出电压、功率密度以及有机物去除率分别为972 mV、16.367 W/m³和99.41%。高通量测序表明，MFC启动过程中，阳极微生物群落的多样性降低，但丰度增加；成熟的阳极生物膜中主要产电微生物是Proteobacteria菌门的Azospirillum（50.89%）、Desulfovibrio（4.38%）、Pseudomonas（2.45%）、Comamonas（1.22%）以及Sphingopyxis（1.26%），Bacteroidetes菌门的Proteiniphilum（1.27%），Firmicutes菌门的Fusibacter（1.3%）等，这是产电性能提升的主要原因。

A two-chamber microbial fuel cell (MFC) using potassium monopersulfate (PMS) as cathode electron acceptor is set up in this study.The performance of simultaneous electricity generation and decontamination as well as the variation characterisitcs of microbial community in the anode are investiagted during the start-up of MFC.It is shown the maximum output voltage,power density and COD removal are 972 mV,16.367 W·m^-3 and 99.41%,respectively when MFC starts up rapidly in one month at 1 000 Ω of R_ext and 10 mmol·L^-1 of PMS.The high-throughput sequencing analysis indicates that the diversity of anodic microbial community decreases during the start-up of MFC,but the abundance increases.Electrochemically active bacteria in the anode biofilm are Azospirillum (50.89%),Desulfovibrio (4.38%),Pseudomonas (2.45%),Comamonas (1.22%) and Sphingopyxis (1.26%) which belong to Proteobacteria,Proteiniphilum (1.27%) of Bacteroidetes and Fusibacter (1.3%) of Firmicutes.The appearance of EAB are the main reason for the improvement of electricity production.
