摘　　要：厌氧氨氧化是微生物和环境领域的重大发现,具有很高的科学和实用价值。研究证明,除了人们最早认识的浮霉状菌外,硝化菌和反硝化菌也有厌氧氨氧化活性。以厌氧颗粒污泥、硝化污泥、自养型和异养型反硝化污泥作为接种物,均可成功启动厌氧氨氧化反应器。在厌氧氨氧化反应器启动过程中,依次呈现菌体自溶、活性迟滞、活性提高和活性稳定4个阶段,根据这种阶段性可及时调控启动过程。实验室和生产性厌氧氨氧化工艺的平均容积基质氮去除速率可达50.75kg.m-3.d-1和9.50kg.m-3.d-1,显示了极高的脱氮效能。Anaerobic ammonium oxidation（Anammox）is an important discovery in the field of microbiology and environmental science and is of scientific and practical valuable.It has been proved that both nitrifying and denitrifying bacteria are also of Anammox activity in addition to planctomycetes known as Anammox bacteria early.To use anaerobic granular and nitrifying sludges,as well as autotrophic and heterotrophic denitrifying sludges as insition,Anammox reactor can be successfully started up.Four phases i.e.bacterial lysis phase,lag phase,exponential growth phase and stationary phase are emerged successively during the start-up,and so the start-up process can be regulated and controlled in time.Super high efficiency of Anammox reactor at both lab-scale and full-scale has been demonstrated with average volumetric nitrogen removal rate of 50.75 kg·m-3·d-1 and 9.50 kg·m-3·d-1,respectively.
