中文摘要：

采用单室无膜悬浮阴极微生物燃料电池（MFc），对比分析了不同处理方式的污泥（直接污泥、微波预处理污泥和酶强化水解污泥）为燃料时MFC产电特性、污泥减量化效果和能源效率，研究表明，酶强化污泥为燃料的MFC（ESMFC）产电周期最长（41d），功率密度最大（775．21mW／m2），但库仑效率（CE）仅10．58％．采用微波污泥为燃料的MFC（MSMFC）CE最高（84．6％），而产电周期（30d）和功率密度（343．41mW／m2）居中．采用直接污泥为燃料的MFc（SMFC）产电周期（15d）、功率密度（294．53mw／m2）和CE（5.8%）均最小．采用直接污泥为燃料的MFC中TCOD去除率为26．2％，VSS去除率为32．5％．采用污泥预处理手段有利于促进污泥减量化，MSMFC和ESMFC中TCOD去除率分别增加到58.5%和58．5％和63．2％，VSS去除率分别增加到73．9％和77．1％。

英文摘要：

A single-chamber, membrane-less and floating-cathode microbial fuel cell （MFC） was established. Electrogenesis characteristic, sludge reduction and energy efficiency in MFC using surplus sludge treated by different ways （original sludge, sludge treated by microwave and hydrolysis sludge strengthened by enzymes） were studied. The electrogenesis cycle was the longest （41d）, the power density was the largest （775.21mW/m2）, and coulomb efficiency （CE） was 10.58% in MFC using surplus sludge strengthened by enzymes （ESMFC）. In MFC using surplus sludge underwent microwave treatment （MSMFC）, the largest CE （84,6%） was obtained. However, the electrogenesis cycle was only 30d, the power density was 343.41mW/m2. In MFC using surplus sludge （SMFC）, the electrogenesis cycle, the power density and CE were 15d, 294.53mW/m2 and 5.8%, respectively. TCOD and VSS removal efficiency by using original sludge MFC were 26.2% and 32.5%, respectively. TCOD removal efficiency by MSMFC and ESMFC were increased to 58.5% and 63.2%, respectively. VSS removal efficiency by MSMFC and ESMFC were increased to 73.9% and 77.1%, respectively. Sludge pretreatment could promote sludge reduction.
