UASB处理猪粪废水启动试验研究王阳

:2007-01-17;:2007-03-02。:,,1968,,。UASB王阳(,110031)　　　:通过UASB反应器处理猪粪废水试验,研究了UASB处理猪粪废水的启动过程。在水浴35℃时,接种处理啤酒废水的厌氧颗粒污泥,通过控制较低的表面水力负荷,经逐步驯化66d,完成了启动过程。结果表明:UASB反应器对COD的去除率为88.5%,其容积负荷达到10.9kg/(m3·d),SS去除率为90.0%或以上。试验可为农村地区资源化技术提供一定的科学依据和借鉴。:UASB;处理;猪粪废水;启动试验1　,、“”、,、、,[1]。,。,2010,45t[1]。,90%。COD7118t,COD,,,[2]。(UASB)、、,,3R(Re-duce,Recycle,Reuse),、、,,———。,UASB,[3-5]。UASB20kg/m3,UASB。2　2.1　20061010,。,1。UASB,90mm,1m,6.5L;1　,(35±1)℃。UASB,,,。2.2　,COD6862mg/L,7120mg/L,SS2200mg/L,pH6.7-7.3。2.3　UASBIC,VSS()SS()0.7,SS41g/L。VSS28.7g/L。3L。23220074　　　　　JOURNALOFMETEOROLOGYANDENVIRONMENT　　　　Vol.23No.2April20072.4　,20℃,1,2℃[5],(35±1)℃。COD2000mg/L,UASB,COD80%、(VFA)400mg/L。COD。。2.5　。COD、、MLSS,MLVSS,pH。1。1　CODHH-5[6]MLSS,MLVSS[7-10]DGB/20-002、pHpHPHS-29ALML-23　3.1　CODCOD2。2,2　CODCOD,COD,88.9%;,,。,COD2000mg/L,52.0%。,,,8d4L/d,18d86.0%,354mg/L。,,。,COD,,。,,、,UASB。UASB66d,COD7100mg/L,COD10.9kg/(m3·d),COD80%。3.2　25℃,(3)。3,3　0.13—0.61m3/kg。,0.46m3/kg。,,,。3.3　SS,UASBSS,SS200mg/L,90.0%。,。352:UASB　　3.4　。,,。,,;。,。,[11-13]。4　HRT　　4,,2L/d,,0.3m/d。,8d0.6m/d,,2。34d,0.6m/d0.9m/d。60d0.9m/d1.6m/d。,15.6h,80%,。3.5　(VFA)(VFA),VFA。,VFA,VFA,,VFA。,VFA400mg/L,;,VFA800mg/L,“”。,pH;[7]。,VFA。5,,VFA,,,。　　,pH,pH。pH2H2CO3(VFA),5　VFA[8-10]。,pH。,CO2H2CO3()。(H2CO3VFA),(pH),。,VFA,[11]。4　UASB,。(1),66d,COD88.5%,SS90.0%,。UASB。(2)0.46m3/kg,。(3)UASB。VFAUASB。[1]　,,,.[J].(),2006,22(4):600-603.[2]　.[M].:,2004:85-86.[3]　,,,.UASB[J].,2006,32(3):20-22.[4]　,,.UASB[J].,2000,18(2):17-19.3623[5]　.[M].:,2001:55-58.[6]　,,.CODBBOD5[J].,2006,22(6):69-71.[7]　,,,.2005[J].,2006,22(6):46-49.[8]　,,,.[J].(),2006,22(3):466-469.[9]　,,,.[J].,2004,11(2):57-60.[10]　.[J].,1997,29(6):32-33.[11]　AustermannHU,SeytriedCF,RosenwinkelKH.UASBreactorinthejuiceindustry[J].WaterScienceandTechnology,1997,36(7):73-82.[12]　GarciaC.Comparisonofthreesupportmaterialsforanaerobicfluidizedbedsystems[J].BiotechnologyLet-ters,2002,18(6):731-736.[13]　Kennedy,KJ.Treatmentoflandfillleachateusingse-quencingbatchandcontinuousflowupflowanaerobicsludgeblanket(UASB)reactors[J].WaterResearch,2000,34(14):3640-3656.Start-upexperimentonpigmanurewastewatertreatmentinUASBreactorWANGYang(LiaoningAcademyofEnvironmentalSciences,Shenyang110031)Abstract:Accordingtotheexperimentofthepigmanurewastewatertreatedbyup-flowanaerobicsludgeblanket(UASB)reactor,itsprocesswasstudiedinthispaper.Underthewaterbathtemperatureat35℃,theanaerobicgranularsludgefromthebeerplantastheseedsludgewastreated.Theprocesswouldbedonebythecontroloflowersurfacehydraulicloadandthedomesticationstepbystep.Theresultsindicatedthattheremovalrateofchemicaloxygendemand(COD)forUASBreactorwas88.5%,thevolumeloadreached10.9kg/(m3·d),andtheremovalrateofsuspendedsolids(SS)wasabove90%.Thistestcouldprovidethescientificbasisandreferencefortheresourceutilizationtechnologyinruralareas.Keywords:Up-flowanaerobicsludgeblanket(UASB);Treatment;Pigmanurewastewater;Start-upexperiment372:UASB
