摘要：

An　experimental　system　consists　of　an　anoxic　biological　filter,　an　aerobic　suspended　carrier　biofilm　reactor　and　an　anaerobic　ammonium　oxidation　(ANAMMOX)　reactor.　Autotrophic　nitrogen　removal　from　sludge　liquor　with　high　concentrations　of　ammonia　and　low　C/N　ratio　was　investigated　in　the　system.　Under　normal　temperature　(15~29°C)　and　high　DO　(6~9mg/L),　the　effluent　ratio　of　nitrite　to　ammonium　of　the　nitritation　reactor　could　be　adjusted　to　meet　influent　substrate　demand　of　the　ANAMMOX　reactor　by　controlling　influent　ammonia　loading　rate　(ALR),　alkalinity/ammonium　ratio,　and　hydraulic　retention　time　(HRT).　When　influent　ALR　and　alkalinity/ammonium　ratio　were　1.16kg/(m3·d)　and　5.1,　effluent　ratio　of　nitrite　to　ammonium　of　the　nitritation　reactor　was　about　1.2　with　more　than　90%　of　nitrite　accumulation　efficiency　and　total　nitrogen　removal　efficiency　of　the　ANAMMOX　reactor　was　about　83.8%.
