[Cultivation of ANAMMOX bacteria and the ammonium anaerobic oxidation technology in the plug flow bio-reactor].
It is feasible that the ANAMMOX bacteria can be enriched and cultivated to red granular in plug flow immobilized floc bioreactor. Average ammonium and nitrite removal rate are more than 98 %, and average total nitrogen removal rate is 86% combined with 14% nitrate production; the removal volumetric total nitrogen load is 2.56kg/(m3 x d). The influence of the influent substrate ratio of ammonium to nitrite on reactor's performance has been studied. The granule structure has been observed by the scan electro-microscope.
