[A study on ANAMMOX A2/O process for ammonium-rich leachates].
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.
