废弃油基泥浆处理方法研究

废弃油基泥浆处理方法研究王嘉麟闫光绪郭绍辉孟苗(,102249)针对废弃油基泥浆的特点,通过声化法处理对泥浆中油分进行回收,再加入絮凝剂破坏胶体稳定性,使其固液两相有效分离并通过进一步实验确定处理样品泥浆的最佳操作参数结果表明:通过超声波与化学破乳剂相结合的方法,可以有效地对泥浆中的油分进行回收,回收率可达到80%以上,加入絮凝剂后可使剩余的泥水两相分离,出水COD可降到100mgL以下,透光率达到90%以上,可循环利用废弃泥浆超声波除油率絮凝0,,[1],,,,,[2],,(),111声化法的破乳原理,,,,,[3],,,[4],,,12声化法的清洗原理,100MPa,,,,,,[5],13絮凝剂的破胶原理,,,,;,,;,,Zeta,,221泥浆的主要成分分析-;,[6];(),,;,122声化法除油10g100mL,40mL,65,,,5min;65,25kHz,3min1020088264,,,1%%%%146850440774625076243626863492598369792489575379745(GB26077)2213WY1WY2WY3,100150200250300mgL,,111,WY2,WY2,150mgL2221351015min,,222,,,,,10min,,,,3min2234050607080,,333,,,60,,,,--,,60224,,,22mingmLWY2(mgL-1)()min()min%06056010003536360560053684360560100537782,684%,778%,;WY2536%,,[7]23破胶-絮凝实验研究231,,,,AlCl3CaCl2Al2(SO4)3MgCl2Fe2(SO4)311200882645g60mL,,,1500mgL,,COD,33COD(mgL-1)%AlCl3,,,80CaCl2,,,59Al2(SO4)3,,,16773MgCl2,,,47Fe2(SO4)3,,,204393,AlCl3Al2(SO4)3,,,,,,AlCl3CaCl2MgCl2COD,,Al2(SO4)3232pH5g60mL,2molL,pH,,15mL10%Al2(SO4)3,,COD,454pHCOD4,pH,,pH6~7,,COD110mgL,90%:5pH(1),pH,OH-(Me3+)(2),pH,,,,OH-,pH,(3)-,pH,,Me(OH)3,,(),pHAl2(SO4)3,pH6~72335g100mL,60mL,pH6~7,,10%Al2(SO4)3,,02mL1%PAM,,,COD,676,6,PAM,,Al2(SO4)312200882641500mgL,COD100mgL,90%Al2(SO4)3,PAM7,COD:(1)Al2(SO4)3,,Zeta,,,(2)PAM[8],,,,,,,(3)Al2(SO4)3,Al2(SO4)3,PAMAl2(SO4)3,PAM(4),3,,,:,150mgLWY2,603min,77%1500mgLAl2(SO4)3,,COD167mgL,73%,,pH6~7,30mgLPAM,,COD100mgL,90%,[1],,..,2002,10(4):1618[2],,..,2003,10(2):4344[3]DurandPianaG.ColloidInterfaceSci,1987:368369[4],,..,2000,21(6):97-101[5]..:,1990[6]..:,1987[7]SaoHengKwong,KochDL.Collisionofslightlydeformable,highrenoldsnumberbubbleswithshortrangrepulsiveforce.PhsFluids.1994,6(8):25912605[8]..(),2004,35(1):[e-mail]2007-11-08,,,,,,,,,,,,,,,,,23;,,10%;,15%~20%,,,,,,摘自中国环境报1320088264STUDYONCEMENTINGMATERIALPREPAREDBYSMELTFLYASHFROMOILSHALEWuYingliangNiWenWangHaixiaetal(7)AbstractThecementitoussystempreparedbysmeltflyashofoilshale,clinkerandgypsumwasstudiedinthispaper.Basedonthechosenactivatorkindsofcementitioussystem,thecombinationandconcentrationofactivatorwereoptimized.Itisproventhatunderthestandardcuringconditions,the28dcompressivestrengthofthecementingmaterialisupto45MPa,whensmeltflyashofoilshale,clinker,gypsum,activator1,activator2andactivator3are64%,215%,6%,2%,05%and6%respectively.KeywordssmeltflyashofoilshaleactivatorstrengthcementingmaterialpozzolanicactivityRESEARCHONMETHODFORTREATINGWASTEDOILBASEDSLURRYWangJialinYanGuangxuGuoShaohuietal(10)AbstractAeconomicalandeffectualmethodhasbeenadoptedonthebasisofthecharacteristicsofthewastedoilbasedmudbyaddingdemulsifierandultrasonictreatmenttorecoveroil,andthenflocculantisusedtodestroythestabilityofcolloidandseparatethesolidfromliquid.Theoptimumoperatingparameterofthesampleslurryisdeterminedbyfurthertest.Theresultindicatedthattheoilintheslurrycanberecoveredeffectivelybythecombinationofaddingdemulsifierandultrasonictreatment,andtherecoverycanreach80%.Thesolidcanbeseparatedfromliquideffectivelybyflocculant.CODoftheeffluentcanbeloweredtounder100mgL,lighttransmissionratioisupto90%,whichcanbeutilizedcircularly.KeywordswastedslurryultrasonicoilremovalrateflocculationSOLIDIFICATIONOFMUNICIPALSOLIDWASTEINCINERATIONFLYASHBYSLAGCEMENTITIOUSMATERIALZhangDajieLiuWenshiTianXiaofengetal(14)AbstractAfteraddingslagcementitiousmaterialtoMSWIflyashatdosageof25%,30%,35%and45%,whosecompressivestrengthandheavymetalleachingconcentrationat7d,28dand60dcuringtimesweremeasuredandmicrographandhydratedproductswereanalysedbySEMandXRD.Resultsshowthatallthesolidifiedsamplescanreachthelandfillstandardsafter60dcuring.Whenslagcementitiousmaterial(35%)isaddedtoflyash,thesolidifiedeffectisthebestoneandthesolidifiedsamplesreachthelandfillstandardsbyonly28dcuring,whichshowsthatMSWIflyashandslagataproperproportioncanproduceasynergisticeffect.KeywordsMSWIflyashheavymetalsleachingslagsolidificationBASICSTUDYONRECYCLINGOFMETALSCRAPSWITHACTIVEPULSEDAIRFLOWSongShuleiHeYaqunZhaoYueminetal(17)AbstractTheseparationmechanismandmetalrecyclingofactivepulsedairflowwerestudied.Researchesonmovementlawsofequalsettlingparticlesbyhighspeeddynamicanalysissystemshowthatlowdensityparticlescangethigheraccelerationthanhighdensityparticles.Sothedensitydominantseparationofparticlescanbeachievedduetothedifferenceofacceleration.Theseparationwithexperimentsonthecrushedmatterswithaparticlesizeof05~20mmfromthewastedprintedcircuitboardsshowthatactivepulsedairflowcanachievehigherseparationefficiencythanconventionalsteadyairflow.Whenthepulsedfrequencyis2.0Hz,theseparationefficiencyofactivepulsedairflowis5%~15%higherthanthatofsteadyairflow.KeywordsactivepulsedairflowequalsettlingparticlesaccelerationmetalrecyclingSTUDIESONTHEINITIALPROCESSOFPREPARINGMnZnFERRITEBYWASTEMnZnBATTERIESRECYCLINGZhangLingsongZhangJunxiLiXueetal(21)AbstractThispaperdescribestheinitialprocessofrecyclingwasteMnZnbatteriesforsynthesizingZnMnferritemagneticmaterialsbyusingmixedacidasleachantsandreductantasadditive.Theeffectoftheformulationofleachingsolution(includingtheproportionofacidsandreductant)ontheextractionofthew
