碩士 === 大葉大學 === 環境工程學系研究所 === 106 === The purpose of the current study is to explore the impacts of diverse additives, where added green Chitosan (CS) proton exchange membrane (PEM) and under the operation of Microbial Fuel Cells (MFC), on electricity production efficiency and pollution reduction. The six additives include graphite (GP), graphene (GR), graphene oxide, (GO) Nanotubes (NT), silver powder (Ag), and sodium alginate (Alg). In addition to the additives, this study also explores the electricity production efficiency, and the effects of wastewater pollution treatment produced by PEM, which was composed during different crosslinking time. The results shows that the maximum power density can achieve 191.8mW/m2 (852.3mW/m3) when combining 2 grams of CS with 0.15 grams of Ag under the operation of MFC in 2-hour crosslinking time. In addition, the maximum chemical oxygen demand removal can achieve 70 percent when combining 2 grams of CS with 0.15 grams of GR under the operation of MFC in 2-hour crosslinking time. From the above, the best MFC operation effect can achieve when adding PEM combined with Ag, than other additives. Additionally, the results of PEM crosslinking time indicates that there is no significant impact on the increase of power density and the span of crosslinking time. Moreover, the dissolved oxygen concentration in Anode wastewater averagely lowers 70%, the electrical conductivities increase 54% averagely, and the pH value lower to 6.2 after all the operation of MFC.
