If EGSB reactor was inoculated with the aerobic activated sludge, then after the reactor start-up operation of 120 d, Granular sludge can be formed. Denitrification bacteria and anaerobic ammonium oxidation bacteria were cultured and enriched for 270 d in EGSB reactor with nitrite and ammonium. The removal efficiency of COD was 85%, ammonium nitrogen 35%, nitrite nitrogen 99.9% and total nitrogen 67% The removal rate of COD, ammonium nitrogen, nitrite nitrogen and total nitrogen were determined .It is shown that the integration of Methanogenesis bacteria, denitrification bacteria and anaerobic ammonium oxidation bacteria and the characteristic of granular sludge in EGSB reactor can be affected by pH, temperature, DO, redox potential, nitrite and COD.
