Abstract Three column Sequencing Batch Reactor (SBR) (R1, R2, R3) with reactor height/diameter ratio of 3:1, 4.5:1 and 6:1 were used in this experiment. The actual domestic sewage was taken as influent and inoculate the sludge returned from the secondary sedimentation tank of the sewage treatment plant. Study the impact of SBR height/diameter ratio on the formation,nitrogen and phosphorus removal and decarburization of aerobic granular sludge in domestic sewage. The results showed that R1, R2, R3 are started successfully with 42,35 and 28d respectively. The average size of the aerobic granular sludge in R1, R2 and R3 are 750, 900 and 1100μm when the granules have matured. In the start-up stage, The removal rates of TN of R1, R2 and R3 are 66%, 61% and 62%, respectively. After the granular sludge matured, the effluent of R1, R2 and R3 all reachesⅠA standard of the Urban Sewage Treatment Plant Pollutant Discharge Standard of China, and the removal rates of TN, TP and COD are 79%, 85% and 91%, 91%, 93% and 94% and 89%, 92% and 93% respectively. Further analysis shows that within the scope of this experimental study, the increase of SBR height/diameter ratio is beneficial to the formation of aerobic granular sludge and increasing the size, so that the precipitation performance and the simultaneous, nitrogen and phosphorus removal performance improved.
