| 中文摘要 |
| 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ANAMMOX A2/O工艺比普通A2/O工艺的TN去除率提高15%～20%,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NH4+-N、NO3--N和NO2--N的反应级数均为1级,反应速率常数为-3.43E-5 L2·(mmol2·h)-1. |
| 英文摘要 |
| 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 A2/O process for the ammonium-rich leachate. It is increased by 15%～20% compared to the A2/O process without ANAMMOX. NO2--N concentration and NO2--N/NOx--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 NH4+-N,NO2--N and NO3--N are 1.The reaction constant is -3.43E-5 L2·(mmol2·h)-1. |
