【Abstract】 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·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.更多还原
