UASB厌氧处理系统处理柠檬酸废水郝雯娣

UASB厌氧处理系统处理柠檬酸废水郝雯娣　李红宇　刘青岩　唐　一　　　采用UASB反应器进行柠檬酸废水处理试验。试验利用准中温UASB处理工艺,进水温度约30℃,pH值5.0～6.0,设计COD负荷为10kg/(m3·d)。稳定运行阶段厌氧系统COD去除率可达90%以上,辅以接触氧化处理系统,COD总去除率达96%以上,出水浓度基本稳定在300mg/L以下,其余各项指标也稳定达标。试验过程中培养出了颗粒污泥。　柠檬酸废水　颗粒污泥　UASB反应器　厌氧消化0　,,。,,,。、、,,14600t/aCAM()50000t/aCAM,COD12000mg/L。。,,。199712,UASB(),。90,。1　1.1　,,SS,,UASB(1)。30℃,pH5.0～6.0。(PULSAFEEDERSERIES/MOD150/0.68,A-MARICAN),10L/h,。。1　　　:(1)UASBV=299L,HRT=29.0h(2)UASBV=101.2L,HRT=10.1h(3)V=153L,51.48L,101.52L,HRT=15.3h,,2。(4)V=17.27L,HRT=1.73h56.1h。1.2　,,,、、、、;、。,。1。　Vol.25　No.10　199941　　　DOI:10.13789/j.cnki.wwe1964.1999.10.016　　,30℃,pH5.0～6.0。,,。,。,20gVSS/L;。N、P,,;、,,UASBpH,UASB,。1.3　(COD=1000mg/L),3,5,。80%。15,UASB85%,3090%。COD3.0kg/(m3·d)(UASB)10kg/(m3·d),。,。,。,COD,250mg/L。35,NH3-N0。,。1　/m3/dCOD/mg/LBOD/mg/LTN/mg/LTP/mg/LTSS/mg/LCa2+/mg/LSO2-4/mg/L1300～150018000～2200011000～1200035387.9400～500400～500150～180200020007.530.62～20003500～10500180～20040～501000～15001.4　,COD、、pH、SS,(VFA),VFA,CO2H2,CO2H2VFA。,VFA。,VFA。,,VFA。pHVFA:VFA,pH,。,“”。,pH,pH6.5～8。。2　2.1　90,。2.1.1　,2　UASB。,UASBCOD9.0kg/(m3·d)～11.0kg/(m3·d)(2)。:UASB90%,96%～98%42　　　　Vol.25　No.10　1999(3);COD300mg/L(4)。,,UASB10%,,UASB40%。3　COD4　COD,(2):,B/C(BOD/COD)0.65,UASB0.3,UASBCOD2　　　UASB-1UASB-272COD/mg/LBOD/mg/LB/C1120079400.7111108063220.4022514.10.061709.40.0677COD/mg/LBOD/mg/LB/C1120072600.658333000.368084390.54231240.112197.30.0379COD/mg/LBOD/mg/LB/C1240087400.708422540.306842000.2928721.30.0735780.0281COD/mg/LBOD/mg/LB/C15400121000.799893610.377833060.39267130.0524260.02　　:。,B/C,B/C0.06。2.1.2　NH3-N5,NH3-N。,,。,。,,。5　NH3-N2.1.3　TP6,,,,。,,。6,TP,。6　TP2.1.4　COD　Vol.25　No.10　199943　　　。,。,6.50m3/(m3·d),0.58m3/kgCOD。,:。,,;,。,。,,24360m3,。2.1.5　,。55～60,。20℃,COD,,COD92%(3)。,,,81～83COD14kg/(m3·d),COD97%,,。2.2　,,,UASB。30,,。,50,,。,12000mg/L,1mm～3mm,,。3,,COD,90%,,UASB。F420。F420420nm470nm,F420,。,。,F420,。。2.3　UASB,UASB,UASB,。UASBCOD10%。,UASB:(1),,SS。SS,,,。,,UASB40%。(2),UASBCOD,B/C。UASB。。(3)NH3-NTP,UASB。(4),,,,,。(5)UASB,COD。UASBCOD1000mg/L,,,。(6),,44　　　　Vol.25　No.10　1999,,,;,,,。3　(1),UASB。10kgCOD/(m3·d),UASBCOD90%,COD96%,。　(2),UASB,。(3),UASB0.58m3/(kgCOD·d)。,。(4),。(5),UASB。,。。(6),UASB,UASB,UASB。,,、UASB,,,。,、、,,UASB。参考文献1　..:,19922　HabetsLHAandJNKnelissen.PulpandPaper,1985,(4):66～693　LettingaG.Anaerobicreactortechnology1In:lstInt.Courseonanaero-bicandlowCostTreatmentofWastesandwastewaters.TheNetherlands:IACandWAC,19944　KatoMT.AnaerobicTreatmentofLowStrengthSolubleWater.PhDThesis.TheNetherlands:WAU,19945　,.--.,1997,15(1)6　,,,.,1997,12:45～467　SchraaGandWJJewell.JWPCE,1984(56):226～2328　HulshoffPolLWetal.WatSciTechnol,1983,(15):291～3049　LettingaG.Fundamentalsofanaerobicdigestion2in:lstInt.CourseonAnaerobicandLowCostTreatmentofWasterandWastewaters.TheNetherrlands:IACandWAU,199410　...199811　()..:.1988:100081　:[phone]　:1999-3-12　Vol.25　No.10　199945　　　WATER&WASTEWATERENGINEERINGVol.25No.10October1999CONTENTSPracticeofTubularSedimentationTankwithFoledePlatesforFlocculationRenLietal(27)…………………………………………Abstract:Thedesign,construction,installationandcommissionofatubularsedimentationtankwithacapacityof70thousandcu-bicmetersperdayarepresented.Thetankwasmountedwithfoldedplatesforflocculation.Theauthorsindicatedthattheappropriateselectionofflocculationtoimprovethemixingandformationofflocksandcarefulsystemcommissiontofindoutthebestoperatingpointareessentialtocontroltheturbiditylevelofoutputwaterandtoreducethealumconsumptioneffectively.FormationandReformationoftheCombinedSewerSysteminShenzhenSpecialEconomicZonePengJietal(30)…………………Abstract:Asaresultoftheinharmoniccoordinationinplanningandconstructionofmunicipalfacilities,someproblemshavebeenleftbehindthecombinedsewersysteminShenzhenspecialeconomiczone,Suchasthesesthelackofuniformadministrationofsewernetwork,thedisorderedconnectionofcourtyarddrainagesystemtomunicipalsewermainsandthepoorqualityofsewerlines.InordertorealizethepannedgoalofthemunicipalgovernmentofShenzhencity,theratioofsewagetreatmentwillbeupto50%attheendofthisyear,somerecommendationswithfeasbilityareproposedbytheauthors.Physical-ChemicalTreatmentoftheWasteLiquidfromUltra-FiltrationofElectrophoreticProcessingZhangLinshengetal(33)…………………………………………………………………………………………………………………Abstract:Physical-chemicalprocesswasresearchedexperimentallytotreatthehighconcentratedwasteliquidfromtheultra-filtra-tionofelectrophoreticprocessinginautomobilefactory.Atwo-stageprocessofcoagulationsedimentationandchemicaloxidationandcorrespondingoperationparametershavebeenformulated.UnderthisconditionaremovalofCODof80%willbeobtained.MycoticTreatmentofSugar-ContentingWastewaterofOrganicAcidProcessingZhaiSujunetal(37)…………………………………Abstract:ThemycoticprocessdevelopedbyaKoreanfirmtotreatsugar-contentingwastewateroforganicacidprocessingisde-scribedwithtwopracticalexamples,focusingspeciallyonthetechnicalfeatureandthefactorswhichinfluencethereproductionofthemycet.Thisprocesshasadvantagesofbestremovalofpollutants,lowsludgeproductionandlessexpensive.Wethinkitisworthy.WastewaterTreatmentPerformanceinLuoyangLocomotiveplantinHenanProvinceZhangXiumingetal(39)…………………
