The laboratory results showed that both SBRs achieved high efficiencies of phosphorus removal after double sludge residence time. The phosphorus removal efficiency and the TP removed on a unit MLSS were 91.72% and 3.23 mg P/ g MLSS（SBR1）versus 71.70% and 2.91 mg P/ g MLSS (SBR2), respectively. The further study found that both SBRs synthesized energy storages during metabolic process, such as PHA and glycogen. However, glycogen was not observed
