第32卷SBR中反硝化聚磷菌的培养驯化研究杨文婷1,2,沈耀良1,2*(1.苏州科技学院江苏省环境科学与工程重点实验室;2.苏州科技学院环境科学与工程学院,江苏苏州215011)摘要:以某污水处理厂活性污泥作为种泥、生活污水作为原水,采用间歇反应器进行反硝化聚磷菌的培养驯化研究。结果表明,以进水-闲置-厌氧-缺氧-沉淀-排水的运行方式运行40d后,出水PO43--P的浓度稳定在0.2mg/L以下,去除率达95%;出水NH4+-N浓度稳定在8mg/L以下,去除率达90%。NO3--N的消耗量和PO43--P的吸收量呈线性关系,表明采用间歇反应器进行反硝化菌的培养驯化是可行的。关键词:城市污水;SBR;反硝化聚磷菌;脱氮除磷中图分类号:X172;X703.1文献标志码:A文章编号:1003-6504(2009)08-0006-03EnrichmentandCultivationofDenitrifyingPhosphorusRemovingBacteriainSequencingBatchReactorYANGWen-ting1,2,SHENYao-liang1,2*(1.JiangsuProvincialKeyLaboratoryofEnvironmentalScienceandEngineering;2.SchoolofEnvironmentalScienceandEngineering,SuzhouUniversityofScienceandTechnology,Suzhou215011,China)Abstract:Denitrifyingphosphorusremovingbacteriawasenrichedandculturedusingactivatedsludgefromawastewatertreatmentplantwithdomesticwastewaterasrawwaterinasetofsequencingbatchreactor(SBR).Resultsshowedafterthesystemwasoperatedundertheconditionofinfluent-idle-anoxic-settling-dischargefor40days,removalofPO43--PandNH4+-Nwas95%and90%respecti
