Aerobic granular sludge (AGS) has emerged as a novel biotechnology for the effective treatment of both municipal and industrial wastewater. Two of the practical parameters that affect aerobic granule (AG) formation and stability are the feeding strategy and organic loading rate (OLR). In this paper, the impact of feeding strategy and OLR on AG formation and stability are reviewed. The feeding strategy that appears suitable for stable AG formation using all substrates is slow anaerobic feeding. Despite the long duration for AG cultivation at low OLR, compact and stable AG are formed. High OLRs result in fast AG formation but the developed granules are unstable due to the large size resulting from excessive microbial growth. The recommended strategy for stable AG formation with enhanced treatment performance is stressed (high) OLR for fast granule formation followed by reduced OLR to ensure stability. This can be combined with slow anaerobic feeding to select for slow-growing microorganisms and nutrients removers such as phosphate-accumulating organisms (PAOs). Further research is recommended to explore AG formation at high OLR using the slow anaerobic feeding strategy for long-term stability.

好氧颗粒污泥（AGS）已成为一种有效处理市政和工业废水的新型生物技术。影响好氧颗粒（AG）形成和稳定性的两个实际参数是进料策略和有机负荷率（OLR）。本文综述了喂养策略和OLR对AG形成和稳定性的影响。似乎适合使用所有底物稳定形成AG的进料策略是缓慢厌氧进料。尽管长时间在低OLR条件下进行AG培养，仍能形成紧凑而稳定的AG。高OLR导致快速的AG形成，但由于微生物过度生长而导致的大尺寸颗粒，导致发育的颗粒不稳定。推荐的稳定AG形成并增强处理性能的策略是强调（高）OLR以快速形成颗粒，然后降低OLR以确保稳定性。可以将其与缓慢的厌氧饲喂相结合，以选择生长缓慢的微生物和营养去除剂，例如磷酸盐累积生物（PAO）。建议进行进一步的研究，以使用缓慢的厌氧进料策略长期维持高OLR时AG的形成。
