The　effect　and　stability　of　sewage　disposed　by　anaerobic　ammonia　oxidation(ANAMMOX)　process　were　explored　in　ANAMMOX　biological　filtration.Synthetic　wastewater　without　organic　carbon　was　firstly　adopted　as　influent　and　total　nitrogen(TN)　concentration　decreased　from　240　mg/L　to　50　mg/L,　and　then　influent　was　changed　into　sewage　including　organic　carbon,　which　maintained　stable　and　efficient　operation　for　140　d.　The　results　indicate　that　ANAMMOX　biological　filtration　can　keep　good　activity　at　16-24°C.　TN　removal　rate　(NRR)　declines　significantly　with　the　decrease　of　temperature　and　its　varying　pattern　fitted　Arrhenius　Equation,　and　the　actual　activation　energy　is　62.82　kJ/mol.　The　disposal　performance　and　stability　of　the　reactor　were　not　affected　by　the　low　nitrogen　influent,　meanwhile,　as　the　inhibition　caused　by　free　nitrous　acid　(FNA)　decreases,　the　NRR　increases　by　10%.　The　biological　filtration　can　endure　the　high　hydraulic　loading　brought　by　low　substrate,　and　filtration　velocity　should　be　controlled　between　9.00　and　11.21　m/h　integratedly　considering　NRR,　TNR　and　hydraulic　impact.　The　coupling　of　ANAMMOX　and　denitrification　can　be　realised　when　ρC/ρN　is　below　0.3　and　TNR　is　improved　by　10%.　On　the　condition　of　16-24°C,　ρ(TN)　50　mg/L,　ρ(BOD)　15　mg/L,　the　reactor　gets　a　stable　performance　where　average　effluent　TN　is　9.38　mg/L,　average　TNR　reaches　81.00%,　and　average　NRR　is　0.93　kg/(m3·d),　which　reaches　IA　standard　of　the　Urban　Sewage　Treatment　Plant　Pollutant　Discharge　Standard　of　China　for　TN.　The　test　lasted　for　more　than　300　d,　ANAMMOX　biological　filtration　used　to　dispose　municipal　sewage　maintains　stable,　the　characteristic　ratio　of　the　process　is　steady　and　layer　is　not　changed　by　the　variation　of　filtration　velocity　and　organic　carbon　source.
