生物燃料电池处理生活污水同步产电特性研究
, PP. 481-486
Keywords: 生物燃料电池,浓度,温度,动力学
Abstract:
？以某生活污水处理厂缺氧池活性污泥为接种体，以葡萄糖为模拟生活废水，构建双室型微生物燃料电池。利用微生物燃料电池（mfc，microbialfuelcell）实现生活废水降解与同步产电。研究基质降解动力学及温度对mfc电极过程动力学的影响，明确微生物电化学活性、阳极传荷阻抗、阳极电势、电池产能之间的关系，考察库伦效率及cod去除率。研究结果表明，电池功率输出与基质浓度关系遵循莫顿动力学方程：p=pmaxc/（ks+c），其中，半饱和常数ks为138.5mg/l，最大功率密度pmax为320.2mw/m2。葡萄糖浓度较小时，反应遵循一级动力学规律：-dca/dt=kca，k=0.262h-1。操作温度从20℃提高到35℃，生物膜电化学活性不断提高，传荷阻抗从361.2ω减小到36.2ω，阳极电极电势不断降低，同时，峰值功率密度从80.6mw/m2提高到183.3mw/m2。45℃时，产电菌活性降低，峰值功率密度减小到36.8mw/m2。葡萄糖浓度为1500mg/l，温度为35℃时，mfc电化学性能最佳，稳定运行6h后库伦效率为44.6%，cod去除率为49.2%。
