To　achieve　high-efficiency　and　low-consumption　stable　removal　of　municipal　wastewater,　the　start-up　and　nitrogen　removal　performance　of　partial　nitration-anaerobic　ammonium　oxidation(Anammox)　process　were　studied　under　normal　temperature　conditions.　The　results　showed　that　real-time　control　strategy　can　quickly　start　partial　nitrification　under　high　DO　(2.5　mg•L-1)　conditions.　The　unique　structure　of　biofilm　provides　Anammox　bacteria　with　good　anaerobic　environment　in　the　presence　of　dissolved　oxygen.　Overcame　temperature　changes　during　start-up.　After　173　d,　the　removal　rate　of　ammonia　nitrogen　and　nitrite　reaches　more　than　90%,　the　removal　rate　of　total　nitrogen　(TN)　approach　to　80%.　Anammox　filter　started　successfully　after　173　d.　The　nitrogen　removal　performance　of　the　coupled　system　under　different　filtration　conditions　was　studied.　The　results　showed　that　the　total　nitrogen　volumetric　loading　of　the　coupled　system　reached　0.75　kg•m-3•d-1　when　the　filtration　rate　was　0.5　m•h-1.　The　average　concentration　of　TN　in　the　effluent　was　8　mg•L-1.　The　nitrogen　of　municipal　wastewater　could　be　treated　stably　and　efficiently　through　partial　nitrification-anaerobic　ammonia　oxidation　process.　©　All　Right　Reserved.
