摘　　要：随着工业化进程持续推进,我国高盐有机废水年排放量与日俱增,因其种类多、成分杂、盐分高、毒性大等特点,废水处理稳定达标问题日益突出。耐盐好氧颗粒污泥(Salt-tolerant aerobic granular sludge,S-AGS)技术因具有沉降性能好、抗盐冲击强、耐受负荷高等优势,在高盐有机废水处理中极具应用潜力。通过对国内外S-AGS研究现状的调研,总结了S-AGS的理化特性与培育方法,从微生物菌种、菌群与颗粒污泥层面解析S-AGS耐盐胁迫机制,并阐述了其耐盐性能演替与污泥团聚颗粒化过程的互作现象,最后分析了工艺在高盐有机废水处理中的应用现状及现存难点,包括颗粒结构易失稳、耐盐降解性能受限、连续流工况难以颗粒化等。未来有必要从嗜耐盐菌种资源挖掘、功能菌群共生互作机制、颗粒化定向调控策略等方面深入研究,为高盐有机废水S-AGS工艺应用提供理论依据和技术支撑。With the continuous advancement of industrialization,the annual discharge of highsalinity organic wastewater in China is rising.The stable wastewater treatment is becoming increasingly prominent due to its diverse components,high salt content,and high toxicity.Aerobic granular sludge(AGS)technology,with advantages such as high load tolerance,low operating cost,and good settling performance,has emerged as a promising solution of hypersaline organic wastewater.This study conducted a comprehensive review of the extant literature on salt-tolerant aerobic granular sludge(S-AGS),synthesizing the physicochemical properties and cultivation techniques.The review dissected the mechanisms underlying the salt tolerance of S-AGS at the microbial species,community and granular sludge levels,and discussed the interaction between the evolution of salt-tolerant functions and the process of sludge granulation.Additionally,the review evaluated the current applications of S-AGS in the treatment of high-salinity organic wastewater,highlighting challenges such as structural instability,constraints on salt-tolerant degradation capabilities,and the difficulty of achieving granulation under continuous flow conditions.It is imperative for future research to explore the potential of halotolerant/halophilic strains,the mechanisms of symbiotic interactions within functional microbes,and the targeted strategies for granulation.Such endeavors will facilitate the practical application of S-AGS technology in the treatment of high-salinity organic wastewaters.
