Research of Wastewater Treatment Technology and Application Situation on Expended Granular Sludge Bed Reactor

This article introduces the structural characteristics and advantages of expended granular sludge bed for the mass transfer rate from the liquid to the granular and the organic removal efficiency were increased by increasing the ratio of height and diameter of the reactor by adopting effluent circulation technology to raise superficial liquid velocity.And the introduction of anaerobic granular sludge bed expansion starting and the overview of application in the research of wastewater treatment.Also propose a view about its research and application prospects.
