HABR混凝生物接触氧化工艺处理印染废水

HABR//黄瑞敏1,刘欣1,林德贤2,秦四海2(1.华南理工大学环境科学与工程学院,广东广州510006;2.广州市佳境水处理技术工程有限公司,广东广州510730):将传统ABR改进为复合式ABR(HABR),并采用HABR/混凝/生物接触氧化组合工艺处理印染废水,重点考察了HABR的处理效果以及混凝工艺位置的选择结果表明,通过在ABR中增设填料层合理分配各反应室的上升流速和增加污泥回流,明显提高了其对印染废水的处理效果;将混凝工艺置于厌氧和好氧工艺之间,从处理效果和成本方面考虑都是最有利的;当印染废水的COD为400~500mg/L色度为500~600倍SS为200~250mg/L时,组合工艺对COD色度和SS的平均去除率分别可达85.4%95.6%90.9%,处理效果好且稳定:复合式厌氧折流板反应器;生物接触氧化;混凝;印染废水:X703:C:1000-4602(2011)03-0087-04CombinedProcessofHABR,CoagulationandBiologicalContactOxidationforTreatmentofPrintingandDyeingWastewaterHUANGRuimin1,LIUXin1,LINDexian2,QINSihai2(1.CollegeofEnvironmentalScienceandEngineering,SouthChinaUniversityofTechnology,Guangzhou510006,China;2.JiajingWaterTreatmentTechnologyEngineeringCo.Ltd.,Guangzhou510730,China)Abstract:Theanaerobicbaffledreactor(ABR)wasimprovedtohybridABR(HABR),andthecombinedprocessofHABR,coagulationandbiologicalcontactoxidationwasusedtotreatprintinganddyeingwastewater.ThetreatmentefficiencyofHABRandtheselectionofcoagulationlocationwereespeciallyinvestigated.Theresultsshowthatthetreatmentefficiencyofprintinganddyeingwastewaterissignificantlyimprovedbyaddingmedialayer,rationallydistributingtheupflowvelocityineachreactionchamberandincreasingthesludgereturnrateintraditionalABR.Placingthecoagulationprocessbetweenanaerobicprocessandaerobicprocessisthemostfavorableintermsoftreatmentefficiencyandcost.WhentheinfluentCOD,colorandSSare400to500mg/L,500to600timesand200to250mg/Lrespectively,theremovalratesofCOD,colorandSSbythecombinedprocessare85.4%,95.6%and90.9%respectively,withbetterandstabletreatmentefficiency.Keywords:hybridanaerobicbaffledreactor;biologicalcontactoxidation;coagulation;printinganddyeingwastewater,,,/////[1],ABRMcCarty2080,87第27卷第3期2011年2月中国给水排水CHINAWATER&WASTEWATERVo.l27No.3Feb.2011,[2]ABRABR(HABR),HABR//,HABR,1试验材料与方法11,,:CODBOD5(400~500)(150~180)mg/L,500~600,SS200~250mg/L,pH9.0~10.0121,HABR,,,,,ABR;HABRHABR,1Fig.1FlowchartoftreatmentprocessHABR:PVC,PE,,,1.8m0.35m2.6m,1500L,4:,800mm,400L,,0.9m13COD:;pH:pH;:;SSVSS:;DO:2结果与讨论21ABR211ABRABR,,,;,[3~5],ABR,,;,,,,,,,ABR[6],,HABR,2,,;30.5~2mm,;4,110.870.62,,,;,,,2HABRFig.2SchematicdiagramofHABRreactor212HABRHABR,,,,,,,60d,,,1~2mm,88第27卷第3期中国给水排水(3)3Fig.3EffectofHRTinHABRoncoagulation,HABR/,,,,(6%),/COD30%,COD50%,,,,,,,,,23,HABR/(COD130mg/L,30),HRTCOD,HRT,COD,HRT4h,COD50%,COD70mg/L;HRT,COD,CODHRT4h,,COD80mg/L,25,COD,,,,24HABR//,HABRHRT12hHRT4h,1,CODSS85.4%95.6%90.9%,HABRCOD,1Tab.1ExperimentalresultsofcombinedprocessCOD/(mgL-1)/SS/(mgL-1)HABR480260570280220120260130280301203013070302530203结论HABR//,(下转第93页)89黄瑞敏,等:HABR/混凝/生物接触氧化工艺处理印染废水第27卷第3期HRT4.253.75h),MBBR1(201)(251)(301)(351),,MBBR1251,MBBR1TN,30%25%,251,MBBR1201,NO-3NO-2,;251,MBBR1,DO,,TN,MBBR2TN,3结论MBBRMBBR1MBBR2260280L/h,COD,HRT6hCOD,NH+4-NHRT8hHRT8hMBBR1251MBBR2280L/h,COD45mg/L5mg/L,65%95%,(GB189182002)A,,;,,TN30%:[1],.:(2)[M].:,1999.[2]ComettAmbrizI,GinzalezMartinezS,WildererP.ComparisonoftheperformanceofMBBRandSBRsystemforthetreatmentofanaerobicreactorbiowasteeffluent[J].WaterSciTechno,l2003,47(12):155-161.[3]SuvilampiJ,LehtomakiA,RintalaJ.Comparisonoflaboratoryscalethermophilicbiofilmandactivatedsludgeprocessesintegratedwithamesophilicactivatedsludgeprocess[J].BioresourTechno,l2003,88(3):207-214.[4],,,.[J].,2007,23(9):77-80.[5],,,.DOMBBR[J].:,2006,34(4):514-517.E-mail:[e-mail]:2010-08-07(上接第89页)HABRHRT12hHRT4h,COD70mg/LSS20mg/L25,85.4%95.6%90.9%,ABR,ABR(HABR),,,,HRT:[1],,,.[J].,2003,23(4):23-27.[2],.[J].,1999,32(6):35-38.[3],,,.[J].,1999,15(7):18-20.[4],,,.[J].,2005,25(9):2297-2303.[5]BarberWP,StuckeyDC.Theuseoftheanaerobicbaffledreactor(ABR)forwastewatertreatment:areview[J].WaterRes,1999,33(7):1559-1578.[6]BarberWP,StuckeyDC.Nitrogenremovalinamodifiedanaerobicbaffledreactor(ABR):1,denitrification[J].WaterRes,2000,34(9):2413-2422.E-mail:[e-mail]:2010-08-2793刘建广,等:两级MBBR深度处理高氨氮生活污水的研究第27卷第3期
