Analysis for the Impact of Loadings in the Formation Process of Aerobic Granular Sludge

Abstract:

The aerobic granular sludge was cultivated in the self-designed sequencing batch reactors (SBR) using ordinary flocculent activated sludge as seeding sludge. In this experiment the effect of different load on the formation of aerobic granular sludge is studied. The formation process of aerobic granular sludge and the capacity of denitrification and phosphorus performance are discussed and characterized. It shows that higher sludge loading is beneficial to the formation of aerobic granular sludge, and mature aerobic granular sludge has high sedimentation speed and the very good decontamination ability. The removal rates of COD, NH4⁺_{Subscript text}-N and TP are 97%, 85% and 95%.
