Abstract：

In　order　to　promote　the　engineering　applications　of　anaerobic　ammonium　oxidation(ANAMMOX)　for　urban　sewage　treatment,　the　impact　of　nitrate,　phosphate,　ammonia　and　nitrite　on　the　running　performance　of　ANAMMOX　biofilter　reactor　at　room　temperature　was　investigated　respectively.　Experimental　results　show　that　there　is　no　significant　impact　on　the　TN　removal　load　when　the　influent　NO3--N　concentration　is　increased　to　about　500　mg/L.　However,　the　TN　removal　load　will　drop　obviously　when　the　infulent　TP　concentration　is　higher　than　10　mg/L,　which　can　be　restored　after　stopping　dosing　phosphate.　Appropriately　increasing　the　concentration　of　NH4+-N　and　NO2--N　is　beneficial　to　the　improvement　of　TN　removal　load.　At　room　temperature　conditions,　nitrate　basically　has　no　effect　on　the　ANAMMOX　biofilter　for　municipal　wastewater　with　low　ammonia.　But　for　phosphate,　it　has　a　certain　impact　on　the　activity　of　ANAMMOX,　and　the　improvement　of　the　influent　phosphate　concentration　has　a　reversible　inhibition　for　ANAMMOX　reaction　in　the　urban　sewage　with　low　ammonia.
