In recent years,one-stage partial nitrification and anammox( anaerobic ammonium oxidation) technology was widely concerned because of its great advantages. In this review,principle,influence factors,reactor types and applications of the onestage partial nitrification and anammox technology were introduced respectively. The influence of temperature,p H,substrate concentration,dissolved oxygen( DO) were analyzed in the process. The characteristics of different one-stage partial nitrification and anammox reactors configurations were summarized. Meanwhile,nitrogen removal efficiency of granular sludge and biofilm were compared. Moreover the existing problems and development trend of one-stage partial nitrification and anammox technology were presented.
