Effects of Acetate on Metabolism of Anaerobic Ammonium-Oxidizing Bacteria

Abstract:

Anaerobic ammonium oxidation (anammox) process is a heated researched biotechnology for nitrogen removal in wastewater. The application of the process is limited due to its long start-up time and sensitivity to organic matters. This paper discussed the effects of acetate on anammox process. The nitrogen removal rate of anammox process was elevated at low acetate content (1 mmol/L) and decreased at high acetate content (3 and 4 mmol/L). The ratios among NH₄⁺-N, NO₂^--N and NO₃^--N were not related acetate content and remained at 1:1.50:0.07, but the ratios between acetate and three forms of nitrogen were acetate dependent.
