Abstract:An experimental system consists of an anoxic biological filter, an aerobic suspended carrier biofilm reactor and an anaerobic ammonium oxidation (ANAMMOX) reactor. Autotrophic nitrogen removal from sludge liquor with high concentrations of ammonia and low C/N ratio was investigated in the system. Under normal temperature (15~29℃) and high DO (6~9mg/L), the effluent ratio of nitrite to ammonium of the nitritation reactor could be adjusted to meet influent substrate demand of the ANAMMOX reactor by controlling influent ammonia loading rate (ALR), alkalinity/ammonium ratio, and hydraulic retention time (HRT). When influent ALR and alkalinity/ammonium ratio were 1.16kg/(m3·d) and 5.1, effluent ratio of nitrite to ammonium of the nitritation reactor was about 1.2 with more than 90% of nitrite accumulation efficiency and total nitrogen removal efficiency of the ANAMMOX reactor was about 83.8%.
