Paper Title:
Synergistic Nitrogen Removal by Anaerobic Ammonium Oxidation-Denitrification Integrated Reactor of Immobilized Microbe
  Abstract

The upflow anaerobic immobilized microbe reactor of the anaerobic ammonium oxidation process (ANAMMOX) was used in treatment of high nitrogen concentration organic wastewater, which was made to study the effect of synergistic nitrogen removal by ANAMMOX–denitrification. The experimental results showed that the mass concentrations of NH 4+-N and NO - 2-N in the influent had no obvious influence on the synergistic nitrogen removal in opportune range. When the mass concentrations of NH 4+-N and NO2-N in the influent were kept at 301-800 mg/L, the removal rates of NH 4+-N, NO2-N and TN were 93.3 %, 98.6 % and 90.3 % respectively. When the influent COD was kept at 800-850 mg/L, COD had almost no influence on the synergistic nitrogen removal, and the removal rate kept at 95.7%. Meanwhile, the characteristic changes of NO3-N, N2, pH value and organism proved that the synergism was in a good state. Introduction
