钢渣处理技术的环境性能比较柴文波

　　　201129钢渣处理技术的环境性能比较＊柴文波　丁　晓　孙　浩(,　　243002)　:随着钢铁工业的快速发展,大量钢渣弃置堆积,不仅成为环境污染源,而且占用大量的土地。目前钢渣处理技术较多,其中主要的处理方法有冷弃法、热闷法、热泼法、浅盘法、水淬法、风淬法等。本研究采用生命周期评价方法,对主要钢渣处理技术进行评估,定义了生命周期评估边界和清单指标,建立了清单计算模型,得到了不同钢渣处理技术的生命周期清单。为了提高结果的可信性,对模型进行了不确定性分析。结果表明滚筒法和风淬法的环境性能较好,是值得推广的钢渣处理技术。:清单分析;生命周期成本;不确定性分析COMPARISONSOFENVIRONMENTALPERFORMANCEAMONGDIFFERENTSLAGTREATMENTSYSTEMSChaiWenbo　DingXiao　SunHao(AnhuiUniversityofTechnology,Maanshan243002,China)Abstract:Asironandsteelindustrydevelopingrapidly,alargeamountofslagwasstocked.Theyarenotonlythepollutionsources,butalsooccupylargelandarea.Atpresent,lotsofslagtreatmentsystemsaredevel-oped,suchascolddisposalmethod,hotdisintegrationmethod,hotsplashingmethod,instantaneousslagchillprocess,waterquenchingmethodandairquenchingmethod,etc.Inthispaper,themethodologyoflifecycleassessmentisutilizedtoevaluatefiveselectedslagtreatmentsystems.Systemboundaryandmajorarticlesofthelifecycleinventoryaredefined,andthenthelifecycleinventoriesofdifferentslagtreatmentsystemsaredeveloped.Forgettingareliableconsequence,uncertaintyanalysisiscarriedout.Resultsindicatedthatairquenchingandrotarycylindermethodshavethebestenvironmentalperformanceandtheyareworthytopopu-larized.Keywords:inventoryanalysis;lifecyclecost;uncertaintyanalysis＊(208061)。0　,,。,,,,,[1-3]。,,、、、,。:、、、、、[4-5]。:、、、、。,,,,。1　LCA[6]。ISOLCA:、、。,、,,,。1.1　目标与范围217DOI:10.13205/j.hjgc.2011.s1.027　　　201129,,。,。、,,1。1　、kgMJkWhm2CO2kggkg[7]t(0～10mm)t(10～40mm)tt　　、、、、、。,,。,、、、、1。1.2　清单分析1.2.1　,,[8-12]。1.2.2　1):。,a-;b-;c-;d-;e-1　218　　　201129(1)。Ei=∑kvi,km+∑j(∑kvj,km·αj,i)(1):Eii;vi,kik;vj,kjk;αj,iji;m;k,、、。(1)∑kvi,km,i;∑j(∑kvj,km·αj,i),,,,。2):,(2)。(2)∑iEi·Ci,、;∑nBn·Cn,;∑(CD+CM+CH)。S=∑iEi·Ci+∑(CD+CM+CH)-∑nBn·Cn(2):Ci、、;CD;CM;CH。1.2.3　,,,Crystalball。,。、、。2　2.1　生命周期清单和生命周期成本的计算结果2。2　/(kg·t-1)/(MJ·t-1)/(kWh·t-1)/(m2·t-1)CO2/(kg·t-1)/(g·t-1)/(kg·t-1)/(t·t-1)(0～10mm)/(t·t-1)(10～40mm)/(t·t-1)/(t·t-1)/(·t-1)328.00258.1118.360.1234.2038.1849.830.120.160.170.46-9.65329.08256.4519.070.1033.9122.6441.950.120.160.170.46-10.69478.00197.7018.360.0328.3332.1513.880.100.400.320.18-41.82677.1761.716.020.009.057.282.010.100.880.020.00-82.191004.8631.983.180.004.695.661.040.100.860.050.00-80.76　　:。　　2:、,,。、,82.1980.76。,,,,。2.2　不确定性分析结果CrystalBall2。2,。2　2。3。(352)219　　　201129starch-basedpolyurethanefoams[J].JournalofAppliedPolymerScience,1998,68:739-745.[10]CunninghamR,CarrM,BagleyE.Modificationsofurethane-foamformulationsusingzeamayscarbohydrates[J].JournalofAppliedPolymerScience,1992,44:1477-1479.[11]LinL,YoshiokaM,YaoY,etal.Liquefactionofwoodinthepresenceofphenolusingphosphoricacidasacatalystandtheflowpropertiesoftheliquefiedwood[J].JournalofAppliedPolymerScience,1994,52(11):1629-1637.[12]YaoY,YoshiokaM,ShiraishiN.Water-absorbingpolyurethanefoamsfromliquefiedstarch[J].Journalofappliedpolymerscience,1996,60:1939-1949.[13]KurimotoY,TakedaM,KoizumiA,etal.MechanicalpropertiesofpolyurethanefilmspreparedfromliquefiedwoodwithpolymericMDI[J].Bioresourcetechnology,2000,74:151-157.[14],,.(II)[J].,2002,20(4):732-736.[15]HamidY,PejmanH.Preparationandpropertiesofnovelbiode-gradablepolyurethanenetworksbasedoncastoroilandpoly(ethyl-eneglycol)[J].Polymerdegradationandstability,2007,92:480-489.[16]LohX,GohS,LiJ.Hydrolyticdegradationandproteinreleasestudiesofthermogellingpolyurethanecopolymersconsistingofpoly[(R)-3-hydroxybutyrate],poly(ethyleneglycol)andpoly(propyl-eneglycol)[J].Biomaterials,2007,28:4113-4123.[17]MarikoYoshioka,AtsushiMiyata,TadashiYagi,etal.Preparationofpolyolsfrommethyl-α-D-glucosideandcyclicestersfordesignandfabricationofbiodegradablepolyurethanefoams[J].JounalofWoodScience,2004,50:511-518.[18]JianjunGuana,KazuroL,Fujimotoa,etal.Preparationandcharac-terizationofhighlyporous,biodegradablepolyurethanescaffoldsforsofttissueapplications[J].Biomaterials,2005,26:3961-3971.[19]HassanMK,MauritzKA,StoreyRF,etal.Biodegradablealiphat-icthermoplasticpolyurethanebasedonpoly(epsilon-caprolactone)andL-lysinediisocyanate[J].JournalofPolymerScience,PartA:PolymerChemistry,2006,44(9):2990-3000.[20],,,.CO2[J].,2001,17(1):173-174.　　621900　　E-mail　[e-mail]2010-11-29(219)3　/(·t-1)-9.074-0.680-10.636-0.683-35.324-0.183-82.605-0.075-80.420-0.074　　,,1,,。3　、、、、,,,,82.1980.76。,。[1]BhatnagarAmit,JainAK.Acomparativeadsorptionstudywithdif-ferentindustrialwasteasadsorbentsfortheremovalofcationicdyesfromwater[J].JournalofcolloidandInterfaceScience,2005,281(1):49-55.[2].[J].,1994(3):9.[3].[J].,2000(2):27-32.[4].[J].,1999(5):27-28.[5],,.[C]//.2007,:,2007.13-16.[6]ISO14040:1997.Environmentalmanagement-lifecycleassess-ment-principlesandframework[S].[7].[J].,2005,21(3):45-49.[8].[J].,2004(10):17-21.[9],,.[J].,2006,29(7):31-33.[10].[J].,2004(7):31-32.[11],,.[J].,2006,26(4):509-512.[12]BellK.ValuingemissionsfromHermistongeneratingproject[M].Seattle:ConcergenceResearch,1994.　　243002　59　　(0555)2316527E-mail　[e-mail]2011-03-07352
