摘　　要：基于移动床生物膜反应器(moving bed biofilm reactor,MBBR)的研究现状,探讨了厌氧氨氧化工艺的特征与反应机理,分析了基质浓度、有机物、温度、溶解氧等因素对工艺稳定性的影响,结合工程应用实例展望了应用前景。分析表明:低浓度COD和适量NH^(+)_(4)-N/NO^(-)_(2)-N比有利于厌氧氨氧化反应;在实际应用中,需保持低温厌氧氨氧化菌(anaerobic ammonia oxidation bacteria,AAOB)活性;溶解氧和填料流化状态的精准控制可以促进AAOB在MBBR生物膜中富集,从而促进厌氧氨氧化工艺稳定脱氮。Based on the research status of moving bed biofilm reactor(MBBR),the characteristics and reaction mechanisms of the anammox process were discussed.The effects of matrix concentrations,organic matter,temperature,dissolved oxygen and other factors on the stability of the process were analyzed.The application of MBBR was prospected with engineering cases.The analysis showed that a low concentration of COD and an appropriate NH^(+)_(4)-N/NO^(-)_(2)-N ratio were conducive to the anammox process.It was necessary to maintain the activity of low-temperature anaerobic ammonia oxidation bacteria(AAOB)in the practical application.Precise control of DO and the fluidization state of the filler could promote the enrichment of AAOB on the MBBR biofilm,which promoted the stable denitrification effect of anammox process.
