好氧颗粒污泥(AGS)在连续流反应器(CFRs)中的有效启动、培养和维护是其在污水处理厂(WWTP)大规模应用的关键。连续流条件下AGS的成功实施取决于CFR的配置，CFR为污泥提供快速颗粒化所需的选择性压力和水力剪切力(HSF)。近几十年来，在好氧污泥就地颗粒化的CFR配置方面取得了重要进展。综述了连续流造粒的难点，介绍了连续流造粒的反应器结构、造粒机理和造粒特性，并展望了今后的研究方向。为了在未来的主流污水处理厂中实现AGS的应用，推动连续流配置的创新具有重要意义。©2021化学工业学会(SCI)。
Efficient start‐up, cultivation and maintenance of aerobic granular sludge (AGS) in continuous flow reactors (CFRs) is critical for its full‐scale application in wastewater treatment plants (WWTPs). The successful implementation of AGS under continuous flow condition depends on the configuration of CFR that provides the selective pressures and hydraulic shear force (HSF) to sludge required for rapid granulation. Important progress has been witnessed with respect to CFR configurations in recent decades forin‐situgranulation of aerobic sludge. This review summarized the difficulties of granulation during continuous flow, as well as the reactor configuration, granulation mechanism and the AGS characteristics, along with the future research prospects. It is of significance to promote the innovation of continuous flow configuration in order to realize the AGS application in mainstream WWTPs in the future. © 2021 Society of Chemical Industry (SCI).
