摘　　要：好氧颗粒污泥(aerobic granular sludge,AGS)是目前最有前景的污水生物处理技术之一,采用连续流反应器(continuous flow reactor,CFR)进行AGS快速培养的技术近年来受到广泛关注。文中通过综述间歇式反应器(sequencing batch reactor,SBR)工艺实现快速颗粒化的调控方法、CFR强化颗粒化及优化控制,总结了目前SBR工艺实现快速颗粒化的主要措施,以及采用基于SBR颗粒化的原理在CFR中实现快速颗粒化的可行方案,包括选择压优化、饱食/饥饿(feast/famine)条件以及晶核策略(crystal nucleus)等。最后对CFR工艺实现快速颗粒化的应用前景进行了展望,并提出探究SBR中强化颗粒化的策略,将有望在未来更加深入地研究AGS在CFR中的形成机理。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.
