The experiment of removal efficiency of N, P using aerobic granular sludge was performed in a Sequencing Batch Reactor (SBR). The results show that, in the operation period of about 4h, the inlet COD being controlled between 500 and 1200mg/L, under the temperature of 37 degree, the removal rate of aerobic granular sludge to COD, ammonia and nitrogen, nitrate and nitrogen, and TP maintains steadily at 97%,95%,92% and 86% respectively, which shows the structural and biological characteristics of aerobic granular sludge are favorable to the removal efficiency of N, P .
