超滤和反渗透双膜工艺在印染废水回用中的应用王希辉

王希辉1,滕子峰2,盛亚荔2,聂圣芬1(1.,266032;2.,266032)　:由于印染废水成分复杂且不稳定,盐度高,可生化性差,使用常规生化处理方法难以达到最佳回用效果。文章研制了一种新型抗污染超滤膜,结合反渗透技术成功处理印染废水。实践表明,该系统运行稳定,对COD、Cl-的去除效率均可达97%以上;对悬浮物、色度的去除率达到100%。系统出水符合印染车间生产回用水的要求。:;;;:X791　　　:B　　　:1009-3028(2009)03-0024-041　,:2009-04-09:(1972—),,,。,,,。,。,,,5.4.2　50%～60%,50%～40%;,,();。5.5　。5.5.1　,:,;,;、。5.5.2　,、;;,,。:[1]　,,.[J].,2005,(1):5—6.[2]　.()[M],:,2004.[3]　.[M],:,2003.[4]　.PU[J].,1999,(2):34—36.TheMainPointsofDyeingandFinishingProcessonPUBaseClothCAOXiao-hong1,2(1.Xi′anPolytechnicUniversity,Xi′an710048,China;2.SanmingVocational&TechnicalCollege,Sanming365000,China)Abstract:Theprocessandtechnicalpointsofpretreatment,dyeing,post-treatmentofPUbaseclothwereexpounded.Thefactorsaffectingleatherraisingwerediscussedinparticular,andthesolu-tionswereputforward.Keywords:PUleatherbasecloth;dyeingandfinishingprocess;raising·24·　　　　　　　　　　　　　　　　　　　　　　20093　、、,。,,。2　2.1　,1。2.2　,,2。1　CODcr(mg/L)BOD5(mg/L)(mg/L)()pHCl-(mg/L)(CaCO3)(mg/L)100～15020～140≤100≤1006.0～9.0≤2500≤6002　CODcr(mg/L)(mg/L)Mn2+(mg/L)()pHCl-(mg/L)(CaCO3)(mg/L)≤15≤0.1≤0.1≤107.0～8.0≤500≤18()10≤0.1≤0.1≤107.0～8.0—40～70GB5749-2006≤3≤0.3≤0.1≤156.5～8.5≤250≤4503　,,,、,,“++”。3.1　,、,。3.2　,,,。,、、。,,。,99%。3.3　5μm、、。;;,97%。4　4.1　,,,。,。,,,,,。3。3　COD(mg/L)SS(mg/L)()(%)(℃)(MPa)50≤3≤599≤800.80　　,,,。。·25·　20093　　　　　　　　　　　　　　　　　　　　　　4.2　,、、、,,。,、、。,。1,,,,,,,。1　5　5.1　,,。5.2　,,,35%,,90%,。5.3　,,。,99%。5.4　,,,,。5.5　PLC,。,。6　6.1　2,COD115mg/L,COD40mg/L,COD65%。SDI,,,SDI。3,SDI2,。6.2　,,4。COD、Cl-、97%;99%,,100%。7　,1.80/t,,,3.50/t,。8　“++”。,COD、Cl-97%,、·26·　　　　　　　　　　　　　　　　　　　　　　20093　4　CODcr(mg/L)(%)Cl-(mg/L)(%)(mg/L)(%)(μm/cm)(%)10132695102525975871896205025992011839798720985801597203824993014069699224975321098208926994013579599821985671198207629985012969597619985792096210331996011939787912985821398209725997013059687610985761597216232988012549689213985691397210820999013069589712985731597214322991001387958941698579129821652399110125695878159856513972093199912013159687910985791098208228981301283978871997567129820672399140129596786129857813972036209915013049778913985641298206820991601285967781798572109820942699170130298820179856989820922399180129398848199755899820862599100%,。,,,。:[1]　RobinsonT.,McMullanG.,MarchantR.,etal.Remediationofdyesintextileeffluent:Acriticalreviewoncurrenttreat-menttechnologieswithaproposedalternative[J].Biore-sourceTechnology,2001,(77):247—255.[2]　,,./[J],2008,8(2):1021—1025[3]　,.[M].:,2002.[4]　.[J].,2008,49(6):25—27.TheApplicationofDualMembraneUltrafiltrationandReverseOsmosisProcessinPrintingandDyeingWastewaterReuseWANGXi-hui1,TENGZi-feng2,SHENGYa-li2,NIESheng-fen1(1.QingdaoSourceCleanEnvironmentalTechnologyCo.,Ltd.,Qingdao266032,China;2.QingdaoHaishanDevelopmentCo.,Ltd.,Qingdao266032,China)Abstract:Itisdifficulttohaveagoodrecycle-waterperformancebytraditionalbiochemicalmethod,be-causethetextilewastewateriscomplicated,unstable,highsalinityandbadbiodegradability.Anovelantipol-lutionultrafiltrationmembraneandreverseosmosiscombinedmembraneprocesswereappliedforinthetextilewastewatertreatmentandreuse.Itwasshownthatthemembranesystemoperatedstably.Itremoved97%ofCODandCl-containedfromthewastewaterandallsuspendedsubstanceandchrominancefromit.Thewaterproducedbythesystemcanbereusedintheprintinganddyeingplants.Keywords:novelantipollutionultrafiltrationmembrane;reverseosmosis;textilewastewater;productionrecycle-water·27·　20093
