• Abstract:The study presented the method for isolating the heterotrophic nitrifiers and the characterization of heterotrophic nitrification. When influent Ammonia nitrogen concentration was 42.78～73.62 mg/L. The average ammonia nitrogen removal rate was 81.32％ from the bio-ceramics reactor. Sodium acetate and ammonium chloride were used as carbon and nitrogen source. The COD removal rates by microorganisms of strain wgy21 and wgy36 were 56.1％ and 45.45％, respectively. The TN removal rates by microorganisms of strain wgy21 and wgy36 were 65.85％ and 67.98％, respectively. At the same time, the concentration of ammonium nitrogen was with the removal rates of 75.25％ and 84.96%, and it also had the function of producing NO2-N. Sodium acetate and sodium nitrite were used as carbon and nitrogen source. Through the 12 days of the aerobic culture, the rate of remove COD of wgy21 and wgy36 were 29.25％ and 22.08％. NO2-N concentration decreased slowly. Comparison, similarity of wgy21 and many Acinetobacter sp.≥99%, similarity of wgy36 and many Acinetobacter sp.≥99%. Refer to routine physiological-biochemical characteristic determination, further more encidences showed that wgy21 and wgy36 belong to Acinetobacter sp.,respectively.
