Sedimentation properties of activated sludge from the bioreactor with simultaneous nitrification and denitrification are studied in this paper. MLSS was about 2 g/l in the bioreactor, F/M ratio less than 0.4 gCOD/(gMLSSd), average dissolved oxygen concentrations were 0.35–0.75 mg/l. Latin square design method was used in this experiment. The results show that biomass at SND is characterized by high settling velocity. Sludge settling velocity function for this biomass was obtained.
