【摘要】:构建并成功运行了厌氧污泥接种的双室MFC系统,评估了该系统处理模拟氨氮废水的效果,阐明微生物生态同MFC耦合氨氮去除的内在联系。结果表明,接种厌氧污泥的MFC电压输出最高可达523 m V,优于接种普通活性污泥的同型MFC。该双室MFC阳极室对低浓度氨氮废水(53 mg/L)的去除率最高为52.5%,对高浓度氨氮废水(294 mg/L)的去除率最高可达91.4%。基于SEM和DGGE的表征证实,接种MFC运行前后的厌氧污泥生物膜形貌和微生物群落结构都有明显的变化,群落多样性减少,优势种群数量增加,部分为典型胞外电子呼吸菌地杆菌。
[Abstract]:The dual chamber MFC system of anaerobic sludge inoculation was constructed and successfully operated. The effect of the system to simulate ammonia nitrogen wastewater treatment was evaluated. The internal relationship between microbial ecology and MFC coupling ammonia nitrogen removal was clarified. The results showed that the MFC voltage output of the inoculated anaerobic sludge was up to 523 m V, which was superior to the same type MFC. of the common activated sludge as the dual chamber MFC. The highest removal rate of low concentration ammonia nitrogen wastewater (53 mg/L) was 52.5%. The highest removal rate of high concentration ammonia nitrogen wastewater (294 mg/L) was up to 91.4%. based on SEM and DGGE. The morphology and microbial community structure of the anaerobic sludge biofilm and the microbial community structure before and after the inoculation of MFC were obviously changed, the diversity of the community was reduced, and the number of dominant populations was reduced. The amount of bacteria increased in part.
