摘　　要：通过好氧出水回流到厌氧流化床可以实现厌氧氨氧化过程 .对于高浓度氨氮渗滤液 ,ANAMMOX反应可使ANAMMOXA2 /O工艺比普通A2 /O工艺的TN去除率提高 1 5 %～ 2 0 % ,达 32 %以上 ;好氧出水NO- 2 N浓度有较大幅度地降低 ,改善了出水水质 .ANAMMOX反应总反应级数为 3级 ,对NH+4 N、NO- 3 N和NO- 2 N的反应级数均为 1级 ,反应速率常数为 -3 4 3E -5L2 ·(mmol2 ·h) - 1.The ANAMMOX reaction could be realized by recycling the aerobic effluent to the anaerobic fluidized bed. A TN removal rate of 32% could be reached in ANAMMOX A 2/O process for the ammonium\|rich leachate. It is increased by 15%～20% compared to the A 2/O process without ANAMMOX. NO - 2-N concentration and NO - 2-N/NO - x-N ratio in the aerobic effluent are decreased significantly. The effluent quality is improved. The ANAMMOX reaction has a total reaction order of 3, and the reaction orders for NH + 4\|N,NO - 2\|N and NO - 3\|N are 1.The reaction constant is -3.43E-5 L 2·(mmol 2·h) -1.
