高浓度氨氮对SBR工艺处理制药废水的影响黎永坚

SBR黎永坚,　胡晓东,　熊紫娟,　李润祺(广州大学土木工程学院,广东广州510006)　　　:　结合实际工程,考察了高进水氨氮浓度对SBR工艺处理制药废水的影响。结果表明,当SBR进水氨氮浓度350mg/L后,出水氨氮浓度迅速升高,出水COD浓度也呈波动上升,高浓度氨氮对微生物产生了抑制作用,大幅降低了SBR对氨氮与COD的去除率;经过一段时间的驯化,SBR工艺可适应450mg/L左右的进水氨氮。　　:　制药废水;　SBR;　高浓度氨氮:X703　　:C　　:1000-4602(2009)13-0092-03ImpactofHighConcentrationAmmoniaNitrogenonTreatmentofPharmaceuticalWastewaterbySBRProcessLIYong-jian,　HUXiao-dong,　XIONGZi-juan,　LIRun-qi(SchoolofCivilEngineering,GuangzhouUniversity,Guangzhou510006,China)　　Abstract:　Combinedwiththeactualproject,theimpactofhighconcentrationammonianitrogenintheinfluentontreatmentofpharmaceuticalwastewaterbySBRprocesswasinvestigated.Theresultsshowthataftertheammonianitrogenconcentrationintheinfluentismorethan350mg/L,theammonianitro-genconcentrationintheeffluentrapidlyincreases,andtheeffluentCODfluctuantlyrises.Highconcen-trationammonianitrogenhasinhibitoryeffectonmicroorganism,resultinginsignificantdecreaseintheremovalratesofammonianitrogenandCODbySBR.SBRprocesscanadaptto450mg/Lofammoniani-trogenintheinfluentafteraperiodofacclimation.　　Keywords:　pharmaceuticalwastewater;　SBR;　highconcentrationammonianitrogen　　、、,。,,,。,。SBR,,。1　试验部分1.1　、、、。:COD1600～6800mg/L,BOD5280～1800mg/L,NH3-N25～1100mg/L,pH1.5～12。1.2　,[1、2],/(1)。2000m3/d。ABR,32m×13.5m×8.5m,8.0m,18h,3450m3。SBR,SBR3,13.7m×33.0m×6.0m,5.2m,6650m3。SBR,·92·第25卷　第13期2009年7月　　　　　　　　　　　　中国给水排水CHINAWATERWASTEWATER　　　　　　　　　　　　　Vol.25No.13Jul.200912h,2.0h(),8h,1.5h,1.5h,1.0h。1　Fig.1　Flowchartofpharmaceuticalwastewatertreatmentprocess2　结果与讨论(20073),,150mg/L,C∶N100∶5;SBR30mg/L,COD160mg/L,。3,,。,SBR。。:,67,(),142mg/L1098mg/L;79,,1098mg/L395mg/L。:,911,360～608mg/L,。:,111,403～475mg/L。,SBR。,CODSBR,SBR。2.1　SBR2.1.1　SBR、2。2,611,SBR142mg/L,;350mg/L,SBR81.5%89%,,,;350mg/L,SBR,,SBR,7,,22%,350mg/L,SBR,。2　SBR、Fig.2　AmmoniaconcentrationofinfluentandeffluentofSBRinshockperiod2.1.2　CODSBRCOD3。3　SBRCODFig.3　CODremovalinSBRinshockperiod3,COD,SBR350mg/L,COD,SBR,COD,170mg/L350mg/L,COD94%85.5%,COD。SBR,,SBRCOD。SBR,,·93·黎永坚,等:高浓度氨氮对SBR工艺处理制药废水的影响第25卷　第13期,。,721,SBR,,450mg/L,,COD150mg/L。2,SBR。2.2　SBRCODSBR,,COD。111,SBR403～475mg/L,COD96.4%,94.7%;82.6%,98.5%,90.4%。SBR,,。3　结论①　SBR350mg/L,;SBR350mg/L,,COD,,SBRCOD。②　SBR,,450mg/L,。:[1]　.[M].:,2008.[2]　,,,.ABR[J].,2000,16(8):42-44.[3]　,.[J].,2001,21(6):47-50.:13570454343E-mail:[e-mail]:2009-02-18(上接第91页)。,。164COD、SS、NH3-N、TN、TP。,95%,,SS,SSCODSSTPSSTN。SS,。3　结论,;2～7,,SS;,;SS,SS,,。:[1]　ButcherJB.Buildup,washoff,andeventmeanconcentra-tions[J].JAWRA,2003,39(6):1521-1528.[2]　SchuelerTR.ControllingUrbanRunoff:aPracticalMan-ualforPlanningandDesigningUrbanBMPs[M].Wash-ingtonDC:WashingtonMetropolitanWaterResourcesPlanningBoard,1987.[3]　LeeJH,BangKW.Characterizationofurbanstormwaterrunoff[J].WaterRes,2000,34(6):1773-1780.[4]　BrezonikPL,StadelmannTH.Analysisandpredictivemodelsofstormwaterrunoffvolumes,loads,andpollutantconcentrationsfromwatershedsintheTwinCitiesmetro-politanarea,Minnesota,USA[J].WaterRes,2002,36(7):1743-1757.[5]　SagetA,ChebboG,Bertrand-KrajewskiJL.Thefirstflushinsewersystems[J].WaterSciTechnol,1996,33(9):101-108.:13182613892E-mail:[e-mail]:2009-02-20·94·第25卷　第13期　　　　　　　　　　　　　　中国给水排水
