摘要:为提高微生物燃料电池(MFC)的性能,以聚乙烯醇(PVA)为黏合剂,分别以磷钨酸(PWA)和邻苯
二胺(OPD)为改性剂,采用溶液浸渍法制备了 PVA/PWA 和 PVA/OPD 改性膜并搭载于 MFC 系统,以 SEM、
电化学阻抗谱(EIS)、循环伏安法(CV)、吸水率表征了膜的性能,并考察膜改性对 MFC 产电量和化学需氧量
(COD)去除率的影响。结果显示,PVA/PWA 和 PVA/OPD 改性膜均能在一定程度上提升 MFC 性能,但 PVA/OPD
改性膜效果更佳。PVA/OPD 改性膜的吸水率为 14.49%,较常规 Nafion 117 膜(NF)提高了 126.05%。采用 PVA/OPD
改性膜的 MFC 在测试周期内的产电量为 101.75 J,较采用 NF 时提高了 587.50%;对阿莫西林制药废水的 COD
去除率为 66.2%,较采用 NF 时提高了 48.4%。基于 PVA/OPD 的膜改性方法对提高 MFC 的产电性能和废水处
理效果有显著作用。

Abstract: To improve the performance of microbial fuel cell (MFC), polyvinyl alcohol (PVA)/
phosphotungstic acid (PWA) and PVA/o-phenylenediamine (OPD) modified membranes were synthesized
by solution impregnation method with PVA as adhesive, PWA and OPD as modifier, respectively, and then
mounted on MFC system. The membranes were characterized by SEM, electrochemical impedance
spectroscopy (EIS), cyclic voltammetry (CV) and water absorption for property analysis, followed by
investigation on the effects of membrane modification on the MFC power generation and the removal rate
of chemical oxygen demand (COD). The results showed that, though both PVA/PWA and PVA/OPD
modified membranes improved the MFC performance to a certain extent, PVA/OPD exhibited better
efficacy. The water absorption of PVA/OPD modified membrane was about 14.49%, 126.05% higher than
that of the conventional Nafion 117 membrane (NF). The output energy of MFC with PVA/OPD modified
membrane in the test cycle was 101.75 J, 587.50% higher than that of MFC with NF, and the COD removal
rate of amoxicillin pharmaceutical wastewater was 66.2%, which was 48.4% higher than that of MFC with
NF. Therefore, the membrane modification method based on PVA/OPD displayed significant effect on
improving the power generation performance and wastewater treatment efficiency of MFC.
