Abstract：

In　order　to　realize　efficient　simultaneous　nitrogen　and　phosphorus　removal　in　domestic　wastewater,　a　post-anoxic　SBR　system　was　used.　The　results　showed　that　the　denitrifying　phosphorus　removal　process　was　launched　in　39　days　by　firstly　shortening　the　SRT　to　enrich　phosphorus　accumulating　organisms　(PAOs),　and　then　extending　the　SRT　and　introducing　the　anoxic　phase.　COD,　TP,　NH4+-N　and　TN　removal　efficiency　were　92.9%,　98.4%,　100%　and　98.4%,　respectively.　The　effect　of　influent　carbon-nitrogen　ratio　(C/N)　was　also　investigated.　There　was　no　obvious　change　on　nitrogen　and　phosphorus　removal　efficiency　when　the　decrease　of　C/N　was　below　17.65%　in　a　short　term.　When　it　exceeded　33.3%,　the　system　had　a　bad　performance　on　both　nitrogen　and　phosphorus　removal,　but　in　the　long　run,　the　effluent　COD　concentration　fell,　and　the　proportion　of　denitrifying　phosphorus　accumulating　organisms　(DPAOs)　in　PAOs　increased,　which　supplemented　the　removal　efficiency　of　decline　to　some　extent.　The　cycle　test　indicated　that　pH　and　DO　can　be　the　real-time　control　parameters　which　decided　whether　the　anaerobic　phosphorus　release　and　the　cycle　ended　or　not.　The　reaction　time　and　energy　consumption　of　aeration　could　be　reduced　significantly.　©　2016,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
