摘　　要：叙述了近年来关于匹配型亚硝化过程的研究成果,阐述了匹配型亚硝化控制过程中的生化机理、化学计量比,总结了启动方式以及反应器类型、碱度、p H、DO、水力停留时间等的影响,分析了匹配型亚硝化反应过程中微生物的群落结构和动态变化,认为通过控制ρ(NO_2^--N)/ρ(NH_4^+-N)能够达到适宜厌氧氨氧化的优化基质比,该过程是实现部分亚硝化-厌氧氨氧化联合工艺实际应用的难点。认为需要进一步的探讨和研究的内容有:维持长期稳定的匹配型亚硝化满足Anammox的进水基质需求;从分子生物学的角度进行改良,降低各影响因素对AOB的不利影响;驯化抗冲击负荷能力强且对实际工程应用环境适应性高的AOB,以求为PN-Anammox联合工艺的规模化应用提供条件。The research results about Anammox adopting nitrosation process in recent years,the biochemical mechanism and stoichiometric ratio in Anammox adopting nitrosation control process were clarified.The influence of reactor type,alkalinity,p H,DO and hydraulic retention time on Anammox adopting nitrosation was summarized.The microbial community structure and dynamic changes in Anammox adopting nitrosation process was analyzed.It considered that by controlling theρ（NO2^-N）/ρ（NH4^＋-N）to achieve the optimum matrix ratio to be suitable for Anammox,which is the difficulty of achieving the practical application of PN-Anammox process.Some contents need to be further discussed and researched,such as maintain long-term stable Anammox adopting nitrosation to satisfy the requirement of Anammox influent matrix,to decrease the adverse effect of each influence factor on AOB from the molecular biology perspective,acclimatized AOB with strong resistance to impact load and high environmental suitability,which provide conditions for large scale application of PN-Anammox combined process.
