Effects of SRT and carbon concentration on the PHB of the anaerobic/aerobic SBR process are studied. The results show that by the order of SBR51,SBR10 and SBR52,the maximum PHB content of MLVSS were 9.8%, 5.72% and 18.89%, respectively, while carbon translating ratios were 46%, 34% and 36.3% during the first 20min of aerobic phase and PHB forming rate were 196.6mg/(L x h), 140mg/(L x h) and 295.35mg/(L x h). PHB degradation rate can be described with a first order degradation rate with respect to the PHB content of the cells. Reclamation of PHB should consider from several factors. Carbon concentration gradient is the main factor influencing PHB formation under batch experiment.
