Abstract:
The present disclosure provides an apparatus for enrichment culturing of anaerobic ammonium-oxidizing bacteria, including: a reactor containing a culture medium containing ammonium and nitrite; and activated sludge beads in which the anaerobic ammonium-oxidizing bacteria in the culture medium are supported, wherein the amount of the activated sludge beads is 25-35% based on the volume of the culture medium. Because loss of the anaerobic ammonium-oxidizing bacteria is minimized and the beads have good mechanical strength, the apparatus for enrichment culturing of anaerobic ammonium-oxidizing bacteria can be operated for a long time.
