摘　　要：采用经微波预处理的生物垃圾为底物构建双室微生物燃料电池(MFC),同时考察不同微波时间和功率下MFC产电特性及还原糖、COD_(Cr)的变化。实验结果表明,以生物垃圾为底物的MFC产电周期长达400 h,在同一微波功率(700 W)下,平均电压、最大输出功率密度随微波时间的延长而增大,在180 s时分别达到433 m V、200 m W/m^2,当微波时间(180 s)相同时,随着微波功率的增大,在595 W处出现一个峰值随后下降,平均电压、最大输出功率密度分别达到484 m V、260.8 m W/m^2,COD_(Cr)、还原糖呈整体下降的趋势,长时间和较高功率(<700 W)的微波处理能够有效地提高MFC的工作效率。A double-chamber microbial fuel cell was built using bio-waste pretreated by microwave as substrate,the electricity generation and reducing sugar,COD_（Cr）were studied. The results showed that the electric cycle lasted for nearly 400 h. Under the same microwave power（ 700 W）,the average output voltage and the maximum output power density ascend along with the radiation time,when the radiation time was180 s,the average output voltage and the maximum power density were respectively up to 433 m V,200 m W / m^2. When radiation time kept constant（ 180 s）,the average output voltage and the maximum power density had a peak on the power of 595 W followed by a gradual decrease with the increase of microwave power. The average output voltage and the maximum power density were respectively up to 484 m V,260. 8m W / m^2. COD（Cr）and reducing sugar both showed a downward trend. The performance of MFC could be effectively improved by the longer radiation time and moderate higher microwave power（〈700W）.
