jaue2015065: Study on Bacterial Diversity in Multi-component Composite Bioactive Filler Treated Sewage

Abstract

Through the running of Ordinary SBR reactor, SBR reactor with internal biological filler and SBR reactor with external biological filler, bacterial diversity in multi-component composite bioactive filler treated sewage was studied by Miseq High-throughput sequencing. The results indicated that the bacterial diversity in the three reactors were very high, Saprospiraceae in internal(8.09%) and external(2.86%) is lower than the control group (29.82%), which according with the research that the biological filler can greatly improve the performance of sludge settling. Flavobacteriaceae in internal (6.19%) and external (11.27%) is higher than the control group (0.71%), which according with the research that the biological filler can greatly improve the ability of phosphorus removal.
