Additionally,factors affecting partial nitrificationandANAMMOX were studied. Mathematical model Was alsoapplied inforecasting thebiological nitrogen removal application ofmathematical model effectively shortened the testperiod of thenoveltechnology and accelerated the application USe ofmathematical model Wassignificant totheapplication ofthe technology. The novel process namely partial nitrification-ANAMMOX biological nitrogen removal process,based ongranular sludge,aimed attreating urban wastewater withlow concentration ofammonium andinsufficientbiodegradable carbon thefeasibility ofpartial nitrificationandANAMMOX innormal temperature prehensively Was unique tostudy theprocess intreating low carbon source and annnonia wastewater. Aerobic ammonia-oxidizing bacteria and ANAMMOX bacteriaCanco-exist. Therefore,theANAMMOX bacteria were enriched from mixed sludge of aerobic sludge and anaerobic 5months ofcontinuous anaerobic operation,the ANAMMOX essfully were enriched though keeping them inoxygen—limiting condition at thebeginning(1asted more than 1month). Mosthcterotrophic bacteria therefore were aresdt,the system suitable to aerobicammonia-oxidizing bacteriaandANAMMOX bacteriawas built
