微生物燃料电池处理餐饮废水及同步发电性能研究
, PP. 1506-1512
Keywords: 微生物燃料电池,餐饮废水,产电,废水处理,阴极电解液
Abstract:
？针对食堂餐饮废水,建立微生物燃料电池实验系统,研究微生物燃料电池废水处理与同步发电性能。首先使用fe(no3)3溶液作为阴极电解液进行实验,证明餐饮废水生物降解及产电的可行性;分别采用nacl溶液和k3[fe(cn)6]溶液作为阴极电解液进行对比实验,研究不同运行环境下微生物燃料电池的发电性能和污水净化效果。结果表明,采用nacl溶液和k3[fe(cn)6]溶液作为阴极电解液时的cod去除率分别是30%和22%左右,平均电流密度分别为5.6和5.2ma/m2。在污水稀释比为2:1、nacl电解液浓度为0.4mol/l的情况下,微生物燃料电池系统的发电性能和净水效果达到最佳状态,稳态电流密度为8.8ma/m2,cod去除率为33.3%。
