摘　　要：微生物燃料电池(MFC)在去除污染物的同时产出电能,是一种颇有前景的生态修复手段。本研究选取研究较少的氟氯吡啶酯和高效氟吡甲禾灵为目标污染物,并通过四步法对石墨毡电极进行改性,构建MFC装置,探索MFC在有机污染物修复中的应用潜力。实验证明,改性电极构建的MFC实验前期发电性能优于未改性电极MFC。相较于氟氯吡啶酯,高效氟吡甲禾灵MFC电导率波动幅度较小,修复温和。修复后期,土壤脱氢酶活性均高于第2天初始值。Microbial fuel cells(MFC)are a promising ecological remediation method that produces electricity while removing pollutants.This study selected fluoropyridine ester and high-efficiency fluoropyrrolidone as the target pollutants,and modified the graphite felt electrode through a four step method to construct an MFC device,exploring the potential application of MFC in organic pollutant remediation.The experiment proved that the modified electrode constructed MFC had better power generation performance than the unmodified electrode MFC in the early stage of the experiment.Compared with fluoropyridine ester,high-efficiency fluoropyrrolidone MFC had smaller fluctuations in conductivity and milder remediation.In the later stage of remediation,soil dehydrogenase activity was higher than the initial value on the second day.
