Abstract：In order to achieve real time control of simultaneously nitrogen and phosphorus removal from domestic wastewater by aerobic granular sludge in anaerobic/aerobic SBR, phosphorus shock loading experiments under low temperature and phosphate uptake batch experiments were carried out. The characteristic points of DO, pH value and ORP profiles were parameters for real time control of anoxic denitrification, anaerobic phosphate release, phosphate uptake and nitrification. It is well known that there are three kinds of phosphorus removal bacteria, they can use oxygen, both oxygen and nitrate, as well as all the oxygen, nitrate and nitrite as electron acceptors, respectively. In this work, the ratio of the three kinds of phosphorus removal bacteria to total phosphorus removal population was found to be 14.19%, 74.32% and 11.47%, respectively. Simultaneously nitrification, denitrification, aerobic phosphate uptake and anoxic phosphate uptake could occur in aerobic granular sludge under aerobic condition.
