摘要：

Two　column-type　SBRs　were　used　to　investigate　the　influence　caused　by　granular　activated　carbon　(GAC)　on　the　formation　of　partial　nitrification　granular　sludge　treating　domestic　sewage.　There　was　not　GAC　in　R2　reactor,　but　R1reactor　had　GAC　added　to　the　sludge　mixture.　R1reactor　was　successfully　started-up　in　22th　day,　while　R2　reactor　was　started-up　in　38th　day.　At　the　beginning　of　the　particle　formation,　the　results　showed　that　GAC　could　be　used　as　the　cores,　reducing　the　initial　particle　formation　time.　At　the　same　time,　in　the　whole　running　stage,　EPS　content　of　R1reacor,　especially　the　content　of　PN,　was　significantly　higher　than　that　of　R2　reactor,　which　further　promoted　the　formation　of　partial　nitrification　granular　sludge.　In　addition,　the　ammonia　oxidation　rate　and　the　nitrite　accumulation　rate　of　R1reactor　were　higher　than　of　R2reactor,　and　had　small　fluctuation,　which　showed　that　the　dosing　of　GAC　helped　maintain　the　stability　of　partial　nitrification　granular　sludge　treatment　effect.　©　2016,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
