ANAEROBIC AMMONIUM OXIDATION WITH PLANKTONIC CELLS IN A CONTINUOUS OR SEMI-CONTINUOUS STIRRED-TANK REACTOR

摘要

Anaerobic ammonium oxidation (anammox) with planktonic cells in a redox-stable continuous or semi-continuous stirred-tank reactor (6), the method comprising- performing cultivation of bacteria mediating anaerobic ammonium oxidation in a stirred tank reactor (6),the method further comprising:A) feeding nitrite ions and ammonium ions in at least one liquid feed (30, 31, 32) to the stirred tank reactor (6),B) discharging liquid product from the stirred tank reactor (6),whereini) feeding in A) and discharging in B) are done continuously, orii) feeding in A) is done repeatedly and discontinuously, and when discharging in B) is done, a fraction of the liquid content in the stirred tank reactor (6) is discharged, which is done repeatedly and discontinuously
