Fixed　time-schedule　control　strategy　for　SBR　duration　is　unable　to　adjust　cycle　duration　according　to　input　wastewater　characteristics　and　loading,　which　results　in　an　inefficient　operation,　i.e.　inefficient　energy　consumption　or　poor　control　over　effluent　quality.　A　real-time　control　strategy　for　enhanced　performance　and　energy　saving　was　developed　in　this　research.　Three　laboratory-scale　EBPR　SBRs　with　different　ecology　community　structure　were　applied　to　treat　real　domestic　wastewater.　Continuous　measurements　of　ORP　and　pH　were　related　to　the　dynamic　behaviors　of　anaerobic　phosphorus　release　and　aerobic　phosphorus　uptake　in　the　SBR,　allowing　the　detection　of　phosphorous　removal.　The　knee　point　on　aerobic　pH　profile　provided　information　for　species　structure　of　ecology.　On　basis　of　it,　monitor　strategy　was　specified　to　predict　behavior　of　functional　microorganism.
