高盐度污水生物处理技术研究解庆林

解庆林　李艳红　朱义年　王敦球　游少鸿　张学洪(,541004)　广西涠洲石油终端处理厂污水Cl-浓度在11000～12000mgL,平均为113480mgL,CODCr约为150～400mgL,属高盐度污水。通过对微生物进行驯化,仍可以用生化法处理。研究表明:单一的厌氧生化法和好氧生化法处理污水均不能达标,而厌氧-好氧联合处理效果良好,出水水质稳定,出水CODCr为14～67mgL,可达到国家污水排放一级标准。　高盐度污水　采油污水　生化处理1　,[1～10],,。,,[10～14],。,,CODCr《》(GB8978-96)。,。2　2.1　水质。,1。BOD5CODCr0.39,0.4。。1　pHCl-mg·L-1CODCrmg·L-1BOD5mg·L-1TSmg·L-17.2～7.511000～12000283～392112.2～147.820～317.311348337.513021.5:。2.2　实验方案与工艺流程,,,。,。UASBSBR,UASBSBR。1。　　※UASB※SBR1　2.3　生物污泥的接种与驯化2.3.1　UASB,。,,(2d),1h,50%。。UASB,。2.3.2　SBR,,,,,1h,50%,。,,。3　3.1　室内实验24,UASBSBR,23。,-,SBR,15　　　20044222DOI:10.13205/j.hjgc.2004.02.0044。1。2　UASBCODCrkg·m-3·d-1hCODCrmg·L-1%pH0.244839216458.17.27.30.204839213066.87.27.50.144828311758.67.27.43　SBRCODCrkg·m-3·d-1hCODCrmg·L-1%pH0.04243928079.67.28.60.082428310363.57.28.54　-CODCrkg·m-3·d-1CODCrmg·L-1%pH0.2228363.777.57.28.70.2928330.189.47.28.5:48h,24h。2、3、4,,CODCr0.14～0.24kgm3·d48h,CODCr58.1%～66.8%,pH;CODCr0.04～0.08kgm3·d24h,CODCr63.5%～79.6%,pH。。,CODCr,,。,(2、3)。20～31mgL,21.5mgL,、,3.9mgL1.3mgL,-,0.7mgL。11000～12000mgL,11348mgL,-,11005mgL10746mgL。3.2　现场实验结果,-2　3　。2,。5。5　-dCODCrkg·m-3·d-1CODCrmg·L-1%pH20.2035645.087.47.28.640.1326267.674.27.28.660.2016260.862.57.28.680.2015715.590.17.28.6100.2620720.490.17.28.7120.3326227.089.77.28.6140.2620927.087.17.28.7160.2620913.693.57.28.6:24h,12h。CODCr167～356mgL,CODCr14～67mgL。15mgL,0.3mgL,。4　(1),,。(2),、,。(3),,CODCr167～356mgL,,CODCr14～67mgL。CODCr。16　　　200442221　,..,1999.25(5):307～310.2　,..,2001.21(4):18～19.3　D.H.Doyle,SPE,FluorDaniel(NPOSR),Inc.;A.B.Brown,ETVentures,L.L.C.FieldTestofProducedWaterTreatmentWithPolymerModifiedBentonite,SPE(SocietyPetroleumEngineers)1997.(5):1～6.4　,,..,2002.22(6):23～25.5　,,..,2001.3(1):40～43.6　,,,,.COD.,2001.30(1):47～49.7　,,..,2000.29(6):327～328.8　,..,1999.25(3):35～39.9　,,,.———.,2000.24(4):26～27.10　,,,.—.,1999.20(1):62～64.11　TreatmentandUtilizationofOil-ContainingProduced-WaterinOman,PetroleumEnergyCenter,1999.Survey(9):1～7.12　ChenASC,FlynnJTCasadayAL.Removalofoil,greaseandsuspendedsolidsfromproducedwaterwithceramiccrossmicmicro-filtration.SPEProductionEngineering,1991.(6):131～135.13　RioDeJaneiro.Biologicaltreatmentofoilfieldwastewaterinasequencingbatchreactor.EnvironmentalTechnology,2001.22(10):1125～1135.14　RiodeJaneiro.Oilfieldwastewatertreatmentbycombinedmicro-filtrationandbiologicalprocess.WaterResearch,2002.36:95～104.　　541004　12　(0773)5896271E-mail　[e-mail]2003-05-06UASB管锡　郑西来(,266003)　探讨了UASB反应器的设计问题和改良的可行性。重点介绍并评价了UASB反应器的器内流速关系以及对应的问题。对比第3代厌氧反应器的特点,提出了UASB反应器可行的改良方法。作为改良可行性证据,提供了改良后的实验数据。　UASB反应器　上升流速　设计　颗粒污泥1　,。2040,,1970Lettinga(UpflowAnaerobicSludgeBed,UASB)。UASB、,,。[2]2:①;②。UASB。2　UASBUASB1[1]。1　UASB1UASB1。17　　　20044222APILOT-PLANTSTUDYOFAPPLYINGMICRO-ELECTROLYSISPROCESSTOREUSEOFEFFLUENTFROMPETROLEUMREFINERYZhuXiaobingetal(7)……………………………………………Abstract　Afieldpilot-plantstudywasconductedofapplyingthemicro-electrolysisprocesstoreuseofeffluent(10m3h)fromapetroleumrefinery.Theperformanceofmicroelectrolysisapparatuswasexamined.Foranticorrosivenormofreusewater,corrodedsteelplatesexperimentwasdonebyhangingtheminwastewater.Combinedwithelectrochemistryprinciple,experimentaldatawasanalyzed.Thepilot-plantprocesshasshownitsfavorableefficiencyandremovalratesofCODCr,oilandSSnormsthatwereallover70%,whichshowsgoodtreatmenteffectiveness.Keywords　micro-electrolysis,pilot-plantstudy,effluentofpetroleumrefineryandwaterreuseINFLUENCEOFFREEZING-THAWINGTREATMENTONDEWATERABILITYOFSLUDGEFROMBEANFOODSEWAGEANDITSAPPLICATIONTianYuetal(9)…………………………………Abstract　Inordertostudythesludgedewaterability,aseriesofexperimentswereconductedtodeterminetheeffectsoffreezingtimeandsludgeconcentrationonitsparticlesizedistributing,sedimentabilityandfiltrability.Theproperconditionsofpre-treatmentweredescribedinthispaper.Thestudyshowsthatfreezing-thawingtreatmentcanenlargesludgeparticle,significantlyimproveitssedimentabilityandfiltrability.Thefreezingtimeofconcentratedsludgeisshorterthanthatoftheoriginalone;filtrabilityoffreezingsludgeisbetterthanthatofsludgeadjustedbyflocculant.Furthermore,freezing-thwaingtreatmentdoesn'tincreasetheweightofmudbecauseitneedn'tdoseflocculant;waterconcentrationofsludgetreatedbyfreezing-thawingmethoddecreasesto60%aftermechanicaldewatering,whichis18percentlowerthanthatofsludgetreatedbyflocculation,andthevolumecanbereducedby30%,whichcanpromotetheresourcereclamationandreuseofsludge.Keywords　freezing-thwaing,sludgedewaterabilityandfermentedbeancurdsewageTREATMENTTECHNIQUEOFWASTEWATERFROMPRODUCTIONOFINSTANTNOODLESANDDRINKXuXiang(13)…………………………………………………………………………………………………………Abstract　Theapplicationoffloatation-activatedsludgeprocesstotreatingnoodleandsyrup-drinkwastewaterwaspresented.Itisindicatedbythepracticaloperationprojectthattheprocesshashighefficencyoftreatment,stablewaterqualityofeffluent.Allindexescanmeetthesecond-orderof“OverallSewageDischargeStandard”(GB8978-1996).Keywords　air-floatation,activatedsludgeprocess,wastewaterfromproductionoffastnoodlesandwastewaterfromproductionofdrinkSTUDYONBIOLOGICALTREATMENTPROCESSOFHIGHSALINITYWAST
