With　nitrogen　and　phosphorus　in　water　body　caused　the　environmental　problem,　removal　of　the　nitrogen　and　phosphorus　in　water　body　with　low　cost　has　become　a　challenge　to　the　biological　wastewater　treatment　worldwide.　The　technology　of　nitrite-denitrifying　phosphorus　removal　has　advantages　of　reducing　carbon　source　consumption,　saving　occupied　area,　improving　water　treatment　equipment　utilization,　and　decreasing　sludge　production.　But　it　remains　unclear　about　the　cognition　of　phosphorus　accumulating　organisms　(PAOs),　and　the　stable　operation　of　the　whole　technology　that　ammonia　is　reduced　to　nitrite　and　denitrifying　phosphorus　removal　is　not　reported　at　present.　Simultaneously,　according　to　different　researchers,　PAOs　has　different　classification,　while　the　main　results　of　the　mechanism　with　short-cut　denitrifying　phosphorus　removal　are　phosphate　release　and　storage　energy　in　anaerobic,　then　the　energy　supply　for　denitrifying　phosphorus　uptake　with　nitrite　as　the　electron　acceptor　in　anoxic.　The　effect　of　nitrogen　and　phosphorus　removal　is　influenced　by　temperature,　pH,　the　kind　of　carbon　source,　the　value　of　ρ(C)/ρ(P)　and　other　factors,　so,　in　order　to　achieve　the　stable　and　efficient　treatment　of　sewage　wastewater,　the　reaction　conditions　of　short-cut　denitrifying　phosphorus　removal　is　necessarily　reasonable.　It　is　necessary　to　summerize　the　relevant　research　reported　on　the　nitrite-denitrification　and　phosphorus　removal　to　guide　and　overcome　the　disadvantages　of　the　biological　nitrogen　and　phosphorus　removal.　©　2016,　Beijing　University　of　Technology.　All　right　reserved.
