This paper reviewed the latest research progress of extracellular polymeric substance (EPS) and aerobic granular sludge technology domestically and internationally. Extraction and determination methods of extracellular polymeric substance were introduced. The effects of organic loading,hydraulic shear force,settling time and wastewater quality were analyzed for EPS content. The mechanisms of proteins (PN) and polysaccharides (PS) in EPS on formation and stability and the effect of EPS on granular sludge transfer were discussed. Future study on establishing standard EPS extraction method,mechanisms of EPS components on settleability and effects of other components,including humics,covalent and flocculent inorganics on aerobic granulation,were proposed for mechanisms of EPS on aerobic granular sludge formation and stability.
