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.
