SBBR窦艳艳1,龚为进1,周健2(1.中原工学院能源与环境学院,河南郑州450007;2.重庆大学三峡库区生态环境教育部重点实验室,重庆400045)以SBBR反应器为研究对象,采用函数发生器控制鼓风机的充氧方式,考察充氧方式对SBBR反应器污泥产率和污水处理效能的影响。在水温为25℃、挂膜密度为45%、负荷为1.0kgCOD/(m3填料·d)、最大供气量为150L/h的条件下,采用方波控制的充氧方式污泥产率最小,为0.0208kgMLSS/kgCOD,并且出水效果好。当反应器充氧方式采用正弦波和锯齿波控制时,其平均污泥产率分别为0.0461和0.0497kgMLSS/kgCOD。采用方波控制时的污泥产率比正弦波、锯齿波的分别减少了54.88%和58.15%。充氧方式;SBBR;波形;污泥减量X703A1000-4602201403-0022-05InfluenceofAerationModesonSludgeReductionEfficiencyinSBBRSystemDOUYan-yan1GONGWei-jin1ZHOUJian21.SchoolofEnergyandEnvironmentZhongyuanUniversityofTechnologyZhengzhou450007China2.KeyLaboratoryofThreeGorgesReservoirRegion’sEco-Environment<MinistryofEducation>ChongqingUniversityChongqing400045ChinaAbstractTheinfluenceofaerationmodesonsludgeyieldandsewagetreatmentefficiencywasstudiedbycontrolingthebloweraerationwithfunctiongeneratorinabench-scaleSBBR.Theresultsshowedthatundertheconditionsoftemperatureof25℃biofilmdensityof45%organicloadingof1.0kgCOD/m3·dandthemaximumgasdiffusionamountof150L/hthelowestsludgeyieldwas0.0208kgMLSS/kgCODwhenusingsquarewaveaeration.Theaveragesludgeyieldswere0.0461kgMLSS/kgCODand0.0497kgMLSS/kgCODrespectivelywhenusingsinewaveandsaw-toothwaveaeration.Comparedwithsinewaveandsaw-toothwaveaerationsquarewaveaerationcouldreducesludgeyieldby54.88%and58.15%respectively.KeywordsaerationmodeSBBRwaveformsludgereduction2012ZX07307-0022010SFXM53850%~60%1~4。、。5SB-BR、SBRCASSSBBR。Hu6/SBBRSBBRORP-100~100mV。7·22·第30卷第3期2014年2月中国给水排水CHINAWATER&WASTEWATERVol.30No.3Feb.2014—。SB-BR。SB-BR。1试验装置及方法1.1110L。1Fig.1SchematicdiagramofSBBRdevice1.2COD、NH+4-N、TN、PO3-4-P、SS220~450、42~53、47~89、4.6~6.7、46~115mg/L300、49、62、5.17、75mg/L。1.3、、SBBR。20~25℃、45%、1.0kgCOD/m3·d、150L/h2。MLSS、COD、NH+4-N、TN、PO3-4-P、ORP。2Fig.2Aerationmodesofdifferentwaves2结果及讨论2.1、84.56、11.9913.13g3。61.97%65.26%。38Fig.3Cumulativeexcesssludgeproductionincontinuousoperationfor8weeks、0.0208、·32·.watergasheat.com窦艳艳,等:充氧方式对SBBR系统污泥减量效果的影响第30卷第3期0.04610.0497kgMLSS/kgCOD。、54.88%58.15%。DO0.17~5.86mg/L4。ORP-155.9mV27.4mV5。4DOFig.4VariationofDOinrunningperiodofreactor5ORPFig.5VariationofORPinrunningperiodofreactorORP-300~-200mV-200~0mVORP>08。30min、30minDO150L/h。/9ATP10。150L/h150L/hDODO3.02mg/L5.36mg/L5.55mg/LDO0.03mg/L0.2mg/L。DOORP5h-180.4~-20.5mV。/。150L/hDO5.5h2.27mg/L4.86mg/L6.55.28mg/LDO0.01mg/L0.11mg/LORP-158.6~0.6mVDOORP。。2.2COD、NH+4-N、TN《》GB18918—2002BNH+4-N、TNPO3-4-P1。NH+4-NTNNH+4-NTN6。5hDO5mg/L·42·第30卷第3期中国给水排水.watergasheat.com。1Tab.1EffectofdifferentwaveaerationmodesonpollutantsremovalCOD/mg·L-1220~450300220~450300220~450300/mg·L-133~504137~605221~4937/%81.3~90.686.379.4~85.982.786.6~94.387.7NH+4-N/mg·L-142~534942~534942~5349/mg·L-14.2~8.26.47.2~11.58.92.1~4.63.8/%80.2~89.786.975.3~86.581.890.4~95.792.2TN/mg·L-147~896247~896247~8962/mg·L-122.3~28.425.725.7~32.629.116.1~24.219.2/%50.5~63.758.649.3~57.153.165.6~73.569.0PO3-4-P/mg·L-13.6~5.64.23.6~5.64.23.6~5.64.2/mg·L-11.8~3.12.41.3~2.92.10.9~2.81.8/%36.7~48.242.945.4~53.550.050.2~60.357.16TN、NH+4-NFig.6VariationofTNandNH+4-Ninrunningperiodofreactor1PO3-4-P。ORP-155.9~27.4mV/。ORP>-150mVPRB11。。3结论①、0.0208、0.04610.0497kgMLSS/kgCOD。②。DO0.17~5.86mg/LORP-155.9mV27.4mV/。③COD、NH+4-N、TN37、3.819.2mg/L。1HendrickxTLGTemminkHElissenHJHetal.A-quaticwormseatsludgemassbalancesandprocessingofwormfaecesJ.JHazardMater20101771/3633-638.2ElissenHJHendrickxTLTemminkHetal.AnewreactorconceptforsludgereductionusingaquaticwormsJ.WaterRes200640203713-3718.3.UAFB--MBRJ.20103181851-1857.4.J.2013291519-23.5.SBBRJ.200831598-100.6HuZEricsonJFMackayAAetal.Biomasscharac-teristicsinthreesequencingbatchbiofilmreactorstrea-(下转第30页)·52·.watergasheat.com窦艳艳,等:充氧方式对SBBR系统污泥减量效果的影响第30卷第3期J.2010382111434-1143511442.5GikasPRomanosP.Effectsoftri-valentCrⅢandhexa-valentCrⅥchromiumonthegrowthofacti-vatedsludgeJ.JHazardMater20061331/3212-217.6KarvelasMKatsoyiannisASamaraC.OccurrenceandfateofheavymetalsinthewastewatertreatmentprocessJ.Chemosphere200353101201-1210.7GkhanEU.OccurrenceandremovalofmetalsinurbanwastewatertreatmentplantsJ.JHazardMater20091722/3833-838.8.J.2010161129-134.9.D.2008.10.J.20123361897-1901.11.J.200522217-20.12.3J.200829177-81.13.SBRJ.20113272036-2040.14Fosso-KankeuEMulaba-BafubiandiAFMambaBBetal.MitigationofCaFeandMgloadsinsurfacewatersaroundminingareasusingindigenousmicroorganismstrainsJ.PhysicsandChemistryoftheEarth20093413/16825-829.15JiangHLTayJHLiuYetal.Ca2+augmentationforenhancementofaerobicallygrownmicrobialgranulesinsludgeblanketreactorsJ.BiotechnolLett200325295-99.1988-。E-mailmwj7107@163.com櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆櫆2013-09-03(上接第25页)tingawastewatercontainingsyntheticorganicchemicalsJ.WaterRes2005394710-720.7.—、J.200218939-41.8.ORPJ.2009221-23.9.A+OSAJ.2012662049-2053.10.J.20034144-47.11.D.2010.1983-。E-maildoudouwxq@163.com2013-10-31·03·第30卷第3期中国给水排水.watergasheat.com
