| Abstract: |
| The effect of electron transfer and electrode area on the performance of OCC wastewater treatment by microbial fuel cell was studied. When CODCr concentration in influent was 3000 mg/L, the removal rates of CODCr in closed circuit and open circuit reactors were 93.9% and 83.7% respectively after 14 d, and the electron transfer of microorganism in the anode could promote the degradation of organic matter. When CODCr concentration in influent was 2000 mg/L, electrode areas were 40 and 108 cm2 respectively, the maximum power densities obtained were 292.4 and 96.6 mW/m2 respectively, which was better than the reactors where the waste waters with CODCr concentration of 1000 and 3000 mg/L were treated. The larger the electrode area, the higher the output voltage and removal rate of organic matter, but there was no multiple relationship between the output voltage and the electrode area. |
