网板式SBR反应器快速稳定培养好氧颗粒污泥试验研究的综述报告 Abstract: Thepurposeofthisreviewistoanalyzetheresearchconductedonthecultivationofaerobicgranularsludgeusingarapid-stabilizationmethodinasequencingbatchreactor(SBR)withafixed-bedstructure.Thereviewsummarizestheadvantagesofthemethod,theprocessoftheformationofaerobicgranularsludge,andthekeyfactorsthatinfluencetheformation,stability,andpropertiesofthegranules.Thereviewconcludesbyoutliningthepotentialfuturedirectionsforresearch. Introduction: Thedevelopmentofeffectiveandefficientmethodsforwastewatertreatmentisanimportantareaofresearch.Onepromisingapproachistheuseofaerobicgranularsludge,whichisaformofbiologicaltreatmenttechnologythatutilizesgranularbiomasswithadiameterof0.5-3mm.Aerobicgranularsludgecanremoveorganicmatter,nitrogen,andphosphorusfromwastewatereffectivelywhileminimizingtheamountofexcesssludgeproducedduringthetreatmentprocess.Oneofthekeychallengesassociatedwiththecultivationofaerobicgranularsludgeisthelongstart-uptimerequiredtoinitiateandstabilizethegranulationprocess.Thischallengehasbeenaddressedthroughtheuseofarapid-stabilizationmethodinasequencingbatchreactor(SBR)withafixed-bedstructure,whichhasbeenshowntoreducethestart-uptimetolessthan40days.Thisreviewsummarizesthelatestresearchonthecultivationofaerobicgranularsludgeusingthismethod.
