Abstract：

Aiming　at　the　slow　granulation　time　of　aerobic　granular　sludge,　an　experimental　study　was　carried　out　on　the　ambient　storage　and　activity　recovery　of　simultaneous　nitrification　and　endogenous　denitrification　for　phosphorus　removal　aerobic　granular　sludge.　The　results　showed　that　after　60days　of　ambient　storage　of　aerobic　granular　sludge,　the　structure　of　granular　sludge　was　basically　stabilized,　but　the　activity　of　granular　sludge　was　greatly　reduced,　and　the　pollutant　removal　rate　was　only　30%~40%　of　that　before　storage.　The　function　and　activity　of　aerobic　granular　sludge　could　be　restored　within　60days　after　certain　control　measures　by　inoculating　the　stored　granular　sludge　into　the　reactor.　In　addition,　the　community　structure　of　aerobic　granular　sludge　changed　significantly　after　storage　and　recovery.　Most　of　the　microorganisms　had　reversible　changes　in　their　relative　abundance　and　could　be　restored　to　the　pre-storage　state　after　storage　and　recovery　(including　Defluviicoccus　(GAOs)　and　Flavobacterium　(PAOs)),　which　reconstructed　the　microbial　community　structure　for　simultaneous　nitrogen　and　phosphorus　removal.　©　2024　Chinese　Society　for　Environmental　Sciences.　All　rights　reserved.
