PACPFS絮凝膜分离法处理含油废水李爱阳

PAC-PFS-1,　　1,2,　1(1.,421002;2.,410083)　:采用PAC-PFS絮凝-膜分离法处理含油废水。通过对几种不同的絮凝剂比较,选择较好的絮凝剂,研究了PAC和PFS的原料配比、投加量、絮凝时间对含油废水中的油、CODcr、SS去除率的影响,同时研究了进料流量和操作压力对膜性能的影响,得到了较为适宜的工艺条件。经处理后的含油废水中油、CODcr、SS的去除率分别达到98%、96%、96%以上,出水水质达到国家一级排放标准。:含油废水;PAC-PFS絮凝;膜分离;超滤:X703.1　　　:A:0367-6358(2008)04-204-03StudyonTreatmentofOil-containingFoodWastewaterbyPAC-PFSFlocculation-MembraneSeparationLIAi-yang1,　CAILing1,2,　SONGChu-hua2(1.ChemicalEngineeringDepartment,HunanInstituteofTechnology,HunanHengyang421002,China;2.CollegeofChemistryandChemicalEngineering,CentralSouthUniversity,HunanChangsha410083,China)Abstract:PAC-PFSflocculation-membraneseparationisusedtotreatoil-refiningwastewater.Differentflocculentswerecomparedandbest,thebeatflocculentwasselected.Theinfluenceofthematerialratio,theaddingamount,andtheflocculationtimeofPACandPFSontheremovalratesofoil,CODcr,SSofoilwastewaterwereinvestigated.Atthesametime,theinfluenceoffeedflowrate,operationpressureonmembraneperformancewasinvestigated.Theoptionalseparationconditionswereobtained.Theremovalratesofoil,CODcr,SSoftreatedoilwastewaterreached98%,96%,96%,respectively.Theeffluentwatercouldreachthenationalfirstclassdischargestandards.Keywords:oil-containingwastewater;PAC-PFSflocculation;membraneseparation;ultra-filtration:2007-08-31;:2008-02-03:(06KG59).:(1969～),,,,,。E-mial:[e-mail]　　,、、、。,,。,。:,;;。,、CODcr。。,,。,-。·204·　　　　　　　2008DOI:10.19500/j.cnki.0367-6358.2008.04.004,《》(GB8978-1996)。1　1.1　,1500mg/L、CODcr3000mg/L、SS1800mg/L、500。1.2　;DBJ:4306GDS-3:pHS-29A:756MG-:1.3　:,,。COD:;NH3-N:;SS:;:。1.2　1000mL,,,pH,30min,1h,,,,,,、CODcr、SS。2　2.1　2.1.1　1000mL,,,,、CODcr、SS。1。1　/mg·L-1/%CODcr/%SS/%PAC3054.260.865.1PFS3066.764.370.8PAC-PFS3076.967.986.3　　1,,PAC-PFS,SS。,、。2.1.2　,,2。2　PAC∶PFS()/%CODcr/%SS/%1∶171.564.471.22∶167.462.768.73∶166.960.265.41∶273.366.374.61∶378.468.585.7　　2,PAC∶PFS1∶3,。1∶3。2.1.3　,,3。3　/mg·L-1/%CODcr/%SS/%1040.033.651.42052.449.273.73077.565.487.14075.768.182.95073.267.578.5　　3,,、CODcr、SS,,30mg/L。,,。,,。2.2　2.2.1　,(,),1。1　　　1,。,,,·205·4　　　　　　　,,。50L/h。2.2.2　,,4。4　/MPa00.10.20.30.40.50.60.70.80.9/L·(m2·h)-1010.321.632.143.583.291.495.390.783.6　　,,,、、,。4,,0～0.7MPa,,0.7MPa,,,,,,0.7MPa。2.3　,,。PAC-PFS,,5。5　PAC-PFS-/mg·L-1/%CODcr/mg·L-1/%SS/mg·L-1/%15001798.830009896.718006896.23　3.1　,。1∶3,30mg/L,。3.2　,50L/h,0.7MPa,《》(GB8978-1996)。3.3　-,,,。:[1]　.[M].:,2000.[2]　,.[M].:,2002.[3]　.PACS[J].,2004,35(1):35-37.[4]　　,.[J].,2006,6(1):54-56.[5]　GrytaM,KarakulskiK,MorawskiAW.PurificationofwastewaterbyhybridUF/MD[J].Waterresearch,2001,35:3665-3669.[6]　　,　.[J].,2005,25(4):8-11.[7]　,　,,.[J].,2006,26(4):1-4.[8]　LahiereRJ,GoodiboyKP.Ceramicmembranetreatmentofprtrochemicalwasewater[J].Environmentalprogress,1993,12(2):86-95.(196)[8]　　,,,.[J].,2002,28(5):482-486.[9]　ZhouQuanZK,ChenXD.EffectsoftemperatureandpHonthecatalyticactivityoftheimmobilized-galactosidasefromkluyveromyceslactis[J].BiochemicalEngineeringJournal,2001,9:33-40.　　200712738,(1968～),E-mail。。编辑部　　　　　　　　　·206·　　　　　　　2008
