AB  - To improve the phosphorus (P) removal/recovery efficiency of a biological P 
      removal system, the study used an alternating anaerobic/aerobic biofilter system 
      to treat synthetic domestic sewage with a low carbon (C) to P ratio. The effects 
      of using periodical carbon source amplification for P recovery on the P removal 
      efficiency and the microbial characteristics within the biofilm were 
      investigated. Intracellular storage polymer dyeing, scanning electron microscopy 
      (SEM) observation and fluorescence in situ hybridization (FISH) methods were 
      employed to characterize the changes of microbial communities in the biofilm 
      during three continuous operation cycles of P bio-accumulating-P recovery 
      (PB-PR). The results showed: through three cycles of operation process of PB-PR, 
      the P removal efficiency of biofilter was increased from 60.3%, 82.9%, 86.6% 
      (before P harvesting) to 87.2%, 91.2%, 93.5% (after P harvesting), respectively; 
      the dominant microbial community morphotypes within the biofilter transformed 
      from big cocci to small cocci, bacilli and filamentous and the group of 
      phosphate-accumulating organisms (PAOs) got rising predominance, which was 
      increased from 43% to 70% after three times of PB-PR; the proportion of PAOs in 
      the biofilm increased unceasingly with the height of the up-flow biofilter. The 
      results showed that the periodical carbon source amplification could improve the 
      P removal efficiency of the biofilter and help the PAOs to become the dominant 
      bacteria within the biofilm.
