摘要

Using simulated syrup wastewater and lake silt as substrates, a microbial fuel cell power generationsystem was set up, the effect of nanoscale polypyrrole proton exchange membrane on the performanceof microbial fuel cells was studied. Firstly, using the Nafion membrane MFC and nanoscale TiO2/SiO2proton membrane MFC as comparisons; secondly, by using the methods of surface polymerization andinternal polymerization, FeCl3 and H2O2 were used as initiators, polypyrrole proton exchange membraneand nanoscale polypyrrole proton exchange membrane were prepared, and the performances of severalkinds of microbial fuel cells with different membrane were tested and compared. The result shows that,the performance of MFC with nanoscale polypyrrole proton exchange membrane is the best. Wheninternal polymerized nanoscale polypyrrole proton exchange membrane prepared by using the FeCl3 asinitiator was used as the separator of MFC, the steady output voltage is 17.3 mV, COD removal is 25.24%, and the water uptake of the membrane is 64.37 %; when surface polymerized nanoscale polypyrroleproton exchange membrane was used as the separator of MFC, the state voltage is 14.4 mV, CODremoval is 36.55 %, and the water uptake of the membrane is 54.18%. And when H2O2 was used asinitiator, the steady voltage of MFC with internal polymerized nanoscale polypyrrole proton exchangemembrane is 9.2 mV, COD removal is 19.39 %, and the water uptake of the membrane is 41.59 %; thesteady voltage of MFC with surface polymerized nanoscale polypyrrole proton exchange membrane is8.4 mV, COD removal is 29.38 %, and the water uptake of the membrane is 32.39 %. The nanoscalepolypyrrole proton exchange membrane improved the performance of MFC evidently.
