Research Progress of Rapid Cultivation for Aerobic Granular Sludge in Continuous Flow Reactor
Aerobic granular sludge(AGS)is one of the most promising biological wastewater treatment technologies.Continuous flow reactor(CFR)has been widely used for rapid cultivation of AGS in recent years.The protocols for rapid granulation in sequencing batch reactor(SBR),enhancing granulation with CFR and optimizing CFR are reviewed in this paper.The methods are summarized for realizing rapid granulation in SBR.Based on the principle of SBR granulation,there are some feasible scheme to realize rapid granulation in CFR,which include improving selection pressure,feast/famine condition,strategy of crystal nucleus,etc.Finally,the application prospect of CFR process to achieve rapid granulation is prospected,and the strategy of strengthening granulation in SBR is proposed,which is expected to further study the formation mechanism of AGS in CFR in the future.
