生物电解池氨氧化脱氮产能
DOI: 10.3724/SP.J.1145.2014.04042, PP. 1058-1062
Keywords: 生物电解池,氨氧化,脱氮,氢气,甲烷
Abstract:
以不锈钢筒作为阴极、碳毡作为阳极，阴阳极间利用无纺布作为隔膜构建单室生物电解池，以氨作为唯一电子供体，接入混合菌群，通过恒定不同的阳极电势，考察不同初始浓度氨氮在生物电解池内的氧化与产物的生成情况.结果表明，恒定阳极电势0.2v（vsag/agcl）时，经过5d的运行，初始氨氮浓度200mg/l、400mg/l的氨氮去除率分别为30%、35%，氮气分别积累16.1ml、17.18ml，甲烷分别积累1.18ml、1.46ml；恒定阳极电势0.6v（vsag/agcl）时，初始氨氮浓度200mg/l、400mg/l，氨氮去除率分别为32.4%、36.6%，分别积累氮气16.48ml、17.42ml，积累甲烷1.3ml、1.52ml，未检测到硝态氮和亚硝态氮.循环伏安扫描分析发现，阳极具有明显的氧化还原峰，且不同的阳极恒定电势，导致其氧化还原峰出现偏移.通过电镜扫描，发现阳极微生物细胞表面具有明显的褶皱形状，高通量分析显示阳极微生物中geobacter占24.11%，是优势菌群，在阳极氨氧化过程中起到关键作用.同时发现系统中还存在氢营养型产甲烷菌synergistes（3.8%）以及梭菌clostridium（3.8%）和gordonia（1.85%）等功能微生物.本文研究表明，在生物电解池内，微生物能够以氨氮作为电子供体，通过氨氧化脱氮，并产生氢气和甲烷.
