| 中文摘要: |
| 研究了微生物燃料电池（MFCs）中电子传递和电极面积对OCC废水处理效果的影响。当进水CODCr为3000 mg/L、电极面积为40 cm2时,MFCs反应器和开路MFCs反应器的CODCr去除率分别为93.9%和83.7%,阳极微生物的电子传递作用能够促进有机物的降解；当进水CODCr为2000 mg/L、电极面积分别为40和108 cm2时,MFCs反应器获得的最大功率密度分别为292.4和96.6 mW/m2,优于进水CODCr为1000和3000 mg/L的MFCs反应器；电极面积越大,产生的输出电压越高,有机物的去除率越高。 |
| 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. |
