摘　　要：厌氧工艺是硫酸盐有机废水处理中最具竞争力的技术,厌氧颗粒污泥则是其核心,开展该类废水厌氧处理颗粒污泥特性的研究,对提高其厌氧处理效率具有重要意义。本文综述了硫酸盐有机废水厌氧处理颗粒污泥近年来的国内外研究进展,主要包括颗粒污泥的理化特性(形态及粒径、孔隙、通道及沉降速度、胞外沉积物等)及颗粒污泥的生物学特性(生物活性、微生物形态、组成及分布),并分析了此方面研究工作存在的问题,认为硫酸盐有机废水厌氧处理颗粒污泥活性抑制机理的研究以及从本质上解除这种抑制措施的提出,将是今后需要重点关注的研究内容。Anaerobic treatment process is the most competitive technology in sulphate organic wastewater treatment,and anaerobic granular sludge is the core of this process. The research of characteristics of anaerobic granular sludge is important to increase treatment efficiency in anaerobic sulphate organic wastewater treatment. This paper reviewed the up-to-date research on anaerobic granular sludge of sulphate organic wastewater treatment on an international scale. The main contents included the physico-chemical characteristics of anaerobic granular sludge （morphology and size, pores and channels,settling rate,extracellular precipitates etc.） and biological characteristics of anaerobic granular sludge （ biological activity , morphology , composition and distribution of microbiology）. Some problems in the related research were also analyzed. Future research shall focus on the inhibition mechanism, surface secretion removal and precipitates of granular sludge,and improving biological activity of granular sludge.
