摘要: 设置3组不同阳极底物的微生物燃料电池（microbial fuel cell，MFC）：无添加污泥（对照组）、含化学合成零价纳米铁的污泥（c-nZVI组）和含绿色合成零价纳米铁的污泥（g-nZVI组），拟探究不同来源零价纳米铁（nZVI）对MFC启动的影响。3组MFC经由5个周期启动，实验结果表明，在c-nZVI组和g-nZVI组的启功阶段，高浓度的绿色合成零价纳米铁和化学合成零价纳米铁均对MFC的输出电压产生抑制作用，当MFC成功启动后，零价纳米铁对MFC的输出电压影响不明显。此外，COD去除率、SEM和电化学表征数据表明，绿色合成零价纳米铁相比于化学合成零价纳米铁在电极表面富集程度、对电极表面性质改变以及产电菌活性的抑制作用更弱。

Abstract: To explore the impact of different nano zero valent iron (nZVI) on microbial fuel cells (MFC) in the start-up phase, in this study, MFCs were setting up with different anodic substrates:sludge (control group), sludge containing chemical synthetic nZVI (c-nZVI group) and sludge containing green synthetic nZVI (g-nZVI group),respectively, and MFCs tested by five cycles. In the start-up process of g-nZVI group and c-nZVI group, a high concentration of nZVI could inhibit electricity generation, while nZVI made no essentially change in voltage output after MFC starting successfully. The results obtained from COD removal rate, SEM and electrochemical characterization showed that green synthesis of nZVI, was less likely to enrich on the electrode surface, change the surface electronic properties and suppress bacteria activity in anode to compare chemical synthetic nZVI.
