摘要：The membrane bioreactor (MBR) bioaugmented by Sphingomonas xenophaga QYY with high degradability was used for treating bromoamine acid (BAA) wastewater. The optimal operation conditions were BAA concentration 250 mg/L, without temperature control, aeration amount 0.8 L/min, hydraulic retention time 14.5 h, pH=7. Ribosomal intergenic sequence analysis (RISA) was used to reveal that the community structure changed with the operational parameters. It suggests that the dominant species are Bacilus sp. in the suspended sludge, and microorganisms clicked on the hollow fibrous membrane contain two layers, the first is Filamentous sp., and the second one contains many species such as Filamentous sp., Coccuss sp., Bacilus sp. and so on.
