| 摘 要： | 为了提高剩余污泥为燃料的微生物燃料电池(SMFC)产电性能以及污泥减量化效果,在不同的温度(40、45和50℃)研究单室无膜微生物燃料电池中酶对SMFC产电特性的强化效果.加入单一酶(蛋白酶或α-淀粉酶)的结果表明,随着温度的上升,SMFC功率密度均上升,但40℃时强化效果最明显,与加入失活酶的对照组相比分别增加198％和130％.在40℃下,混合酶比(蛋白酶浓度:淀粉酶浓度)为2∶3时,SMFC最大功率密度为776 mW/m2.随着混合酶中淀粉酶的比例提高,SMFC库伦效率逐渐增加,当混合酶比为4∶1时,CE(库伦效率)可达18.3％,同时TCOD、TSS和VSS去除率分别为70.3％、66.7％和80.4％.因此,温度相对较低时,外加酶强化效果更明显;与单种酶相比,混合酶对SMFC产电性能和污泥减量化的强化效果更显著. |
