摘　　要：颗粒污泥可提高厌氧氨氧化菌截留率和反应器抗冲击负荷能力,因此厌氧氨氧化颗粒污泥(anammox granular sludge,AnGS)是实现其工程化应用重要途径之一.然而,目前对其形成机理缺乏系统理解,故综述AnGS的菌群结构及微生物群落间相互关系与作用,分析了目前提出的各种颗粒化机理,提出了Anammox颗粒化的4个过程以及几种加快氧氨氧化污泥颗粒化的策略,如选择最佳种泥、剪切力控制和添加金属离子等,最后讨论这些策略存在的问题和未来研究方向.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.
