Abstract

Abstract:

High-rate anaerobic reactors with the advantages of less occupied areas, high volume load and stable opera-tion have been widely applied to the treatment of municipal sewage and industrial wastewater.The rapid formation of anaerobic granular sludge is the key to the high-rate anaerobic reactor start-up.In this paper, the methods for accelerating anaerobic sludge granulation in recent years are introduced, and the effects of the optimization of operation conditions, screening dominant bacteria, and the addition of particulate matter, polymer, and metal cations on the acceleration of anaerobic sludge granulation process are discussed emphatically.In addition, the research in future are predicted, so as to provide theoretical basis for the engineering application of anaerobic granular sludge.

Key words: granular sludge, anaerobic technology, wastewater treatment, sludge granulation
