Lab-scale　anaerobic　ammonia　oxidation　and　denitrification　(SAD)　processes　were　operated　simultaneously　in　a　municipal　waste　water　treatment　plant　(WWTP).　Sewage　treated　by　the　A/O　and　nitrification　process　was　used　as　the　substance　to　start　up　an　anaerobic　ammonia　oxidation　filter　reactor.　Adding　glucose　and　sodium　propionate　to　influent　was　used　as　the　substance　to　start　up　the　SAD　filter　reactor　after　the　successful　start-up　of　the　ANAMMOX　reactor.　The　SAD　process　performed　well　with　an　average　total　nitrogen　concentration　in　the　effluent　of　6.41　mg•L-1when　30　mg•L-1　glucose　was　added　to　the　effluent　sewage　at　ambient　temperature.　Compared　with　the　ANAMMOX　process,　the　total　nitrogen　concentration　in　the　effluent　from　the　SAD　process　decreased　42%.　The　stability　of　the　SAD　process　was　destroyed　and　the　SAD　process　turned　into　a　denitrification　process　when　30　mg•L-1　glucose　was　added　in　the　influent　sewage　in　a　low　temperature　environment.　In　normal　and　low　temperature　environments,　the　SAD　process　functioned　well,　and　the　average　total　nitrogen　concentration　of　the　effluent　was　6.54　mg•L-1　when　30　mg•L-1　sodium　propionate　was　added　in　the　influent　sewage.　Compared　with　glucose,　sodium　propionate　had　little　influence　on　the　SAD　process.　©　2018,　Science　Press.　All　right　reserved.
