AB  - In this study, a biological system consisting of an up-flow anaerobic sludge 
      blanket (UASB) and anoxic-oxic (A/O) reactor was established for the advanced 
      treatment of high ammonium urban landfill leachate. The inhibitory effect of free 
      ammonia (FA) and free nitrous acid (FNA) on the nitrifying bacterial activity was 
      used to achieve stable nitritation in the A/O reactor. The results demonstrated 
      that the biological system achieved chemical oxygen demand (COD), total nitrogen 
      (TN) and NH(4)(+)-N removal efficiencies of 95.3, 84.6 and 99.2%, respectively at 
      a low carbon-to-nitrogen ratio of 3:1. Simultaneous denitritation and 
      methanogenesis in the UASB could improve the removal of COD and TN. Nitritation 
      with above 90% nitrite accumulation was successfully achieved in the A/O reactor 
      by synergetic inhibition of FA and FNA on the activity of nitrite oxidizing 
      bacteria (NOB). Fluorescence in situ hybridization (FISH) analysis showed that 
      ammonia oxidizing bacteria (AOB) was dominant and was considered to be 
      responsible for the satisfactory nitritation performance.
