Abstract Anammox granular sludge (AnGS) can improve the retention rate of anammox bacteria, and resistance capacity of the influent load shock, so AnGS is one of the important ways to facilitate the engineering application of anammox technology. However, the knowledge of the AnGS formation mechanism is still lacking. In this review, the structure of AnGS and the relationship and role of microbial communities were summarized, and various granulation mechanisms proposed at present were comprehensively analyzed; also, Four processes of Anammox granulation and several strategies to accelerate ANAMMOX sludge granulation, such as selection of the best sludge, shear force control and addition of metal ions, were proposed. Finally, the problems and future research directions of these strategies were discussed.

Key words： anammox granulation extracellular polymeric substances quorum sensing fast start-up
