摘　　要：厌氧生物处理技术因其具有有机负荷高、污泥产量低、能耗低等优点被广泛应用于各种废水处理中。厌氧颗粒污泥具有沉降性能好、微生物浓度高、有机负荷高等优点,极大地提高了废水处理效率。尤其在处理含高氨氮废水中,厌氧颗粒污泥的形成对反应器的高效生物脱氮至关重要。但到目前为止,厌氧反应器中的颗粒污泥形成及废水处理效果还缺乏系统的认识。鉴于此,总结了厌氧反应器中颗粒污泥的形成机制,分析了影响厌氧反应器中颗粒污泥形成的因素,论述了厌氧反应器中厌氧颗粒污泥生长的模拟,最后介绍了厌氧颗粒污泥在国内外的主流应用。厌氧反应器中颗粒污泥的形成是综合因素影响的结果,对影响厌氧颗粒污泥形成的每个因素都需要认真对待,可为在厌氧反应器中颗粒污泥的培育和应用提供理论指导和技术支撑。Anaerobic biological treatment technology has been widely used in various wastewater treatments because of its advantages of high organic load,low sludge output and low energy consumption.Anaerobic granular sludge has the advantages of good settling performance,high microbial concentration and high organic load,which can greatly improve the efficiency of wastewater treatment.In particular,in the treatment of wastewater containing high ammonia nitrogen,the formation of anaerobic granular sludge is also essential for the efficient biological nitrogen removal in the reactor.But up to now,we still lack a systematic understanding of the formation of granular sludge in anaerobic reactors and the effect of wastewater treatment.So,this paper summarized the formation mechanism of anaerobic granular sludge in anaerobic reactors,analyzed the influencing factors,discussed the simulation of anaerobic granular sludge growth in anaerobic reactors,and finally analyzed the mainstream application of anaerobic granular sludge at home and abroad.The formation of granular sludge in anaerobic reactors is the result of multiple factors,and every factor that affects the formation of anaerobic granular sludge should be treated seriously.The theoretical guidance and technical support for the cultivation and application of granular sludge in anaerobic reactors were provided in this paper.
