ANITAMox自养脱氮MBBR反应器的启动及运行李慧博

ANITAMoxMBBＲ李慧博1，王银爽1，丁娟1，陈晓华1，Ｒ．Lemaire2，Julien．Chauzy2(1．威立雅水务工程＜北京＞有限公司，北京100004;2．威立雅技术部，法国)介绍了一种新型一级全程自养脱氮工艺———ANITAMoxMBBＲ工艺在污水处理厂的启动和运行经验。通过接种来自“苗圃”的负载厌氧氨氧化菌的生物膜填料，来缩短新运行的A-NITAMox工艺的启动时间。2010年第一座ANITAMox反应器在瑞典Malm的Sjlunda污水处理厂建成，在接种3%填料的情况下，启动开始4个月后对NH+4－N的去除率即可达90%，去除负荷为1．2kg/(m3·d)，去除单位质量氨氮的能耗为1．5kW·h，N2O排放量只有0．2%～0．9%。可见，ANITAMox工艺是一种高效、碳排放量低、节能且运行稳定可靠的工艺。厌氧氨氧化;ANITAMox;MBBＲ;启动;脱氮;N2O排放量X703A1000－4602201405－0001－05Start-upandOperationofANITAMoxDeammonificationMBBＲLIHui-bo1WANGYin-shuang1DINGJuan1CHENXiao-hua1Ｒ．Lemaire2Julien．Chauzy21．VWS＜Beijing＞Co．Ltd．Beijing100004China2．VeoliaWaterTechnicalDepartmentFranceAbstractTheexperiencefromstart-upandoperationofANITAMoxMBBＲanew1-stagedeam-monificationprocesswasintroduced．The“biofarmconcept”wasdevelopedinordertodecreasethestart-uptimeofnewANITAMoxinstallationsbyseedingcarrierswithalreadyestablishedAnammoxbio-filmcomingfromthe“biofarm”．ThefirstANITAMoxplantstartedoperationin2010atSjlundaWWTPinMalmreachedNH+4－Nremovalof1．2kg/m3·dand90%NH+4－Nremovalratewith-in4monthsafterstart-upwithonly3%seedingcarriers．Typicalfeaturesofthisfirstinstallationwerelowenergyconsumption1．5kW·h/NH+4－NremovedandlowN2Oemissions0．2%to0．9%．Ｒe-sultsfromfullscaleANITAMoxplantsprovedthisdeammonificationprocesstobearobustandstableprocesswithhighenergyefficiencylowcarbonfootprintandenergysaving．KeywordsAnammoxANITAMoxMBBＲstart-upnitrogenremovalnitrousoxideemissionsAOBAnammox。C/N、、。60%、、。11d。SHAＲON/Anammox1SBＲ2、MBBＲ。·1·第30卷第5期2014年3月中国给水排水CHINAWATEＲ＆WASTEWATEＲVol．30No．5Mar．201434。MBBＲAOB5MBBＲ。ANITAMoxMBBＲ。Sjlunda。。1ANITAMox工艺MBBＲ。MBBＲ1AOBNH+4－NNO－2－NNO－2－N、NH+4－NN2。1/Fig．1Schematicdiagramof1-stagenitritation/Anammoxbiologicalprocessincarrier’sbiofilm。AnoxKaldnesBiofilmChipM1200m2/m3K3500m2/m3AnoxK5800m2/m3。AOBNOB。。NH+4－NNO－3－NNO－3－N。。ANITAMox。12～36MBBＲ7。SjlundaANITAMox“”ANITAMox。2Sjlunda污水厂的ANITAMox工艺Sjlunda38×104m3/d/////MBBＲ/DAF。616000m320d35℃3。60%SBＲ40%200m3ANITAMox。SjlundaNH+4－N855±148mg/LCOD257±67mg/LBOD147±73mg/LHCO－34570±130mg/LTSS330mg/L。4ANITAMoxMBBＲ200kgN/dBiofilmChipM/K3/AnoxK522～33℃pH6．7～8．1DO0．5～1．5mg/L。20108NH+4－N、NO－3－N、pH。3分析方法3.11．6μmNH+4－N、NO－3－N、NO－2－NCOD7。3.2N2O30L/hN2ON2O。·2·第30卷第5期中国给水排水．watergasheat．com3.3BiofilmChipMMBBＲANITAMox。3NH+4－N、NO－3－NTN。3.43LN22L/h。30℃。NH+4－N25mg/L、NO－2－N25mg/L、PO3－4－P2．5mg/L、NaHCO32g/L2mL/L5～10min。4结果和讨论4.1ANITAMox4ANITAMoxMBBＲ1～41MBBＲ1MBBＲ4。MBBＲ12m340．9m3。MBBＲ4211＜0℃12。1MBBＲ1MBBＲ4Tab．1Operationconditionsduringstart-upofMBBＲ1andMBBＲ4MBBＲ1MBBＲ4BiofilmChipMAnoxK5/%4050ANITA0．9m321m34m3K5/%31620108201112/℃18～20－10～52MBBＲ1。280NH+4－N150mg/LNO－3－N100mg/L。NH+4－NNO－3－N8%～15%11%。NOBAOB。2MBBＲ1Fig．2PerformanceofMBBＲ1sincestart-upNO－2－N＜5mg/L120mg/LMBBＲ。NH+4－N4NH+4－N1．2kg/m3·d90%。200～4500．7～1．1kg/m3·d。174246MBBＲ12MBBＲ40%34%。BiofilmChipM。·3·．watergasheat．com李慧博，等:ANITAMox自养脱氮MBBＲ反应器的启动及运行第30卷第5期4504ANITAMox1．3kg/m3·d。NH+4－N90%TN80%。①②③④。MBBＲ43。21m3AnoxK584%AnoxK5。70dNH+4－N300～400mg/L。16%MBBＲ4NH+4－N1．0kg/m3·d。ANITAMox、。3MBBＲ4Fig．3PerformanceofMBBＲ4aftersecondstart-up4.2ANITAMox4.2.1MBBＲ148～60kg/dTN43～56kg/d。0．5～1．5mg/LANITAMoxMBBＲ31．45～1．75kW·h/kgNH+4－NSBＲ50%～60%SBＲ2．9kW·h/kgNH+4－NMBBＲHimmerfjrden2．3kW·h/kgNH+4－NHattingen5．6kW·h/kgNH+4－N。8Sjlunda。4.2.2N2ON2O73～221mg/m30．2%～0．9%N2O2。N2O0．5mg/LMBBＲNH+4－N＜50mg/L。2ANITAMoxN2OTab．2AverageN2OemissionsfromANITAMoxprocess/hN2O/%N2O/mg·m－3425—27553450．9221617—231378550．7204627—28201270．27378—131277800．8212Kampschreur9SHAＲON/N2O2．3%N2O1．7%10。Weissenbacher11SBＲN2O1．5%。SBＲ4．1%N2O12ANITAMox。ANITAMoxVxjSundet213%。NH+4－NTN90%80%。HolbaekGrindstedANITAMox。5结论①ANITAMox·4·第30卷第5期中国给水排水．watergasheat．com。A-NITAMoxMBBＲ200kgN/d4NH+4－N1．2kg/m3·dNH+4－N90%。②“”ANITAMox3%。③BiofilmChipMAnoxK5。④ANITAMox1．5kW·h/kgNH+4－N。⑤ANITAMoxN2O0．2%～0．9%。1AbmaWSchultzCMulderJetal．Full-scalegranularsludgeAnammoxprocessJ．WaterSciTechnol2007558/927－33．2WettB．DevelopmentandimplementationofarobustdeammonificationprocessJ．WaterSciTechnol200756781－88．3ＲosenwinkelKCorneliusA．Deammonificationinthemoving-bedprocessforthetreatmentofwastewaterwithhighammoniacontentJ．ChemEngTechnol200528149－52．4ChenJJiQZhengPetal．Floatationandcontrolofgranularsludgeinahigh-rateanammoxreactorJ．Wa-terＲes201044113321－3338．5CemaG．ComparativeStudyonDifferentAnammoxSys-temsD．StockholmKTH2009．6LemaireＲLivianoIEkstrmSetal．1-stageDeam-monificationMBBＲprocessforrejectwatersidestreamtreatmentinvestigationofstart-upstrategyandcarriersdesignA．ConferenceProceedingsofNutrientＲecove-ryandManagementC．MiamiWEF2011．7APHA．StandardMethodsfortheExaminationofWaterandWastewaterM．WashingtonDCAmericanPublicHealthAssociation1995．8GustavssonD．Biologicalsludgeliquortreatmentatmu-nicipalwastewatertreatmentplants—areviewJ．Vat-ten2010663179－192．9KampschreurMvanderStarWWieldersHetal．Dy-namicsofnitricoxideandnitrousoxideemissionduringfull-scalerejectwatertreatmentJ．WaterＲes2008423812－826．10KampschreurMTemminckHKleerebezemＲetal．NitrousoxideemissionsduringwastewatertreatmentJ．WaterＲes200943174093－4103．11WeissenbacherNTakacsIMurthySetal．Gaseousni-trogenandcarbonemissionsfromafull-scaledeam
