| 1 | Based on MBR Microbial Community Structure Analysis of shortcut nitrification initiation in different kinds of mud显示文摘For clear membrane bioreactor (MBR)Microbial Community structure changes before and after the short-cut Nitrification with different sludge inoculation.MBRNitrifying sludge (R1.),Anaerobic nitrification sludge (R2.)And 1.:1.Mixed inoculation of anaerobic and Denitrifying sludge (R3.)Sludge source for achieving rapid short-cut nitrification.The results show that the combination of Intermittent Aeration and reduced hydraulic retention time (HRT),R1.R2.With R3.Reactor time-consuming 46 d,8 d And 30 d The shortcut nitrification was successfully launched,R2.Shortest startup cycle of Reactor.During the stable operation period,R1.R2.And R3.The average nitrite accumulation rate was 92%,93% And 94%,R3.The reactor showed more stable short-cut Nitrification performance..Ace,Chao,Shannon And Simpson Index results show that after stable operation,R1.And R2.The microbial abundance and diversity of the reactor were significantly lower than that of the inoculated sludge,R3.The abundance of reactor species decreased slightly while the diversity level changed little..After the shortcut nitrification was successfully started,3.The main bacteria in the reactor were Proteus phyla (Proteobacteria)And bacteriocin (Bacteroidetes)And the abundance of the Main Nitrogen Removal Function bacteria is higher than that of the inoculated sludge..Beta-Proteus3.The dominant bacteria in the short-cut Nitrification system of each reactor accounted59. 6%,63. 6%And69. 3%.R1.R2.AndR3.Reactor in the advantage bacteria of are nitrosation single (Nitrosomonas)of proportion respectively up 12. 8%,Natural 20. 2% And 19. 7%.Compared R1 Reactor,R2 And R3 Reactor inoculation sludge in there is a certain proportion of nitrification bacteria more conducive to system short-range nitrification of implementation. | Huang Dianxia Li Ziming | 2019 | Probe-Environmental Science and Technology2019，1，1： | 0 |
