微生物燃料电池（ MFC ）最具应用前景之一是处理废水的同时能够产生电能。以糖蜜废水作为阳极基质，以金属离子的电镀废水做阴极溶液，研究了双室微生物燃料电池不同电极面积对产电性能和COD的影响。结果发现，当外电阻为300Ω时，大反应器微生物燃料电池A1（阳极面积为78．15cm2）及小反应器微生物燃料电池A2（阳极面积为76．8cm2）最大功率密度分别为0．28mW／cm2和0．22mW／cm2。在前200个小时内，A2电池在第60个小时时产生最大电压71．1 mV和最大电流189．5μA，A1在第190个小时时产生最大电压81．1 mV和最大电流228．1μA。同时，当Zn2＋作阴极溶液时，小反应器微生物燃料电池阳极溶液的COD去除率在1．5％到7．02％之间，大反应器微生物燃料电池阳极溶液的COD去除率在0到14．96％之间。阴极中Zn2＋去除率A1中为28．6％，A2为21．2％。

Microbial fuel cell ( MFC) is one of the most application prospect technology in wastewater treatment and at the same time it ’ s able to generate electricity .This article mainly studied the double chamber microbial fuel cell with different electrode area on production performance and the effect of COD , in which molasses wastewater as anode substrate , metal ion plating wastewater as cathode solution .The results show that when the external resistance was 300 Ω, big reactor microbial fuel cell A1(anode area of 78.15 cm2) and small reactor microbial fuel cell A2 ( anode area of 76.8 cm2 ) maximum power density were 0.28 mW/cm2 and 0.22 mW/cm2 .In the first 200 hours, A2 generated maximum voltage 71.1 mV and maximum current 189.5μA (when the battery in the 60 hours), A1 maximum voltage 81.1 mV and maximum current228.1μA(during 190 hours ) .At the same time , when Zn 2+wered as cathode solution , the COD removal rate of small reactor microbi -al fuel cell was at between 1.5%and 7 .02%, the big reactor ’ s COD removal rate was between 0 and 14 .96%. Cathode Zn 2+removal rate was 28 .6%A 1 A 2 is 19 .2%.
