                 摘要:利用阴离子交换膜作为分隔膜构建了生物阴极微生物燃料电池(MFC),通过硝化反硝化过程去除氨氮、
                 降解丙酮同时产电。考察了丙酮质量浓度对 MFC 产电性能及氨氮(质量浓度 200 mg/L)和化学需氧量去除率
                 的影响,采用高通量测序技术分析了阳极及阴极微生物群落结构。结果表明,在丙酮质量浓度为 50~700 mg/L
                 范围内,丙酮的去除率均在 96%以上;当丙酮质量浓度>300 mg/L 时,氨氮的去除开始受到抑制,氨氮最高去
                 除率为 73.7%,且丙酮质量浓度为 300 mg/L 时,对应的 MFC 的产电性能最佳,最高输出功率密度可达

                 49.7 mW/m 。从门级分类上看,阳极中的优势微生物群落主要为变形菌,拟杆菌门及厚壁菌门;阴极上的优
                 势微生物群落为拟杆菌门、放线菌门、变形菌门及酸杆菌门。从属级分类上看,阳极主要的优势菌种为

                 Abstract: Biocathode microbial fuel cell (MFC) was constructed by using anion exchange membrane as
                 separator, which could remove ammonia nitrogen by simultaneous nitrification and denitrification process,
                 degrade acetone and  generate electricity. The effects  of acetone mass concentrations on electricity
                 generation  performance of  MFC, ammonia nitrogen (mass concentration 200 mg/L)  removal rate and
                 chemical oxygen demand removal rate were investigated. The microbial communities of anode and cathode
                 were analyzed by high throughput sequencing technology. The  results showed that the removal rate of
                 acetone  (mass concentration in the  range  of  50~700 mg/L) was more than  96%.  When acetone mass
                 concentration was higher than 300 mg/L, the removal of ammonia nitrogen began to be inhibited, and the
                 highest removal rate of ammonia nitrogen was 73.7%. Besides, when acetone mass concentration was 300
                 mg/L, the corresponding MFC achieved the highest electricity generation performance with the  highest
