单级与两级序批式反应器用于牛场污水处理的比较研究李秀金

李秀金(,100029)　对序批式反应器(SBR)的特点进行了简要的介绍。研究了水力停留时间和有机负荷率对单级和两级SBR用于牛场污水处理时污染物去除率和出水水质的影响,并对单级和两级SBR的污水处理性能进行了比较。研究结果表明,当用单级SBR处理10000mgLCODCr的污水时,1d水力停留时间即可获得较好的处理效果,但出水中仍含有一定量的氨。两级SBR可使用较短的水力停留时间而获得较高的污染物去除率和较好的出水水质,并可通过硝化过程实现氨的完全的去除。　处理　污水　牛场　序批式反应器1　,。,6000,。,,,、。,,。,,SBR。2　2.1　污水来源和特性。、,。,CODCr5000～15000mgL。,CODCr10000mgL。1。2.2　试验方案SBR1,。3(1、2、3d),10、5、3.3gL·d。SBR1:5min、10h30min、50min、5min、30min,112h。SBR1。SBRSBR1,SBR2。SBR2d,(SBR1)(SBR2)1d。SBR1SBR2、、、SBR1。SBR12h,SBR2。,SBR2SBR12h。　3　3.1　单级SBR污水处理性能1。1,SBR。1d2d3d,10、5、3.3gL·d,,。,23　　　20024202DOI:10.13205/j.hjgc.2002.02.007。,,1d10000mgLCODCr。,10gL·d,6d。3dNH3-N1d2d,3。,,。1、23d,6、1015d,NH3-N76.5%79.4%86.3%。,NH3-N,NH3-N。,,3,NH3-N(120～70mgL),3,SBR。。,,。1　SBRd123g·(L·d)-110533%%%CODCrmg·L-110000198080.2158084.2147085.3SCODCrmg·L-12914145750.0145150.2142851.0TSmg·L-16656243663.4247662.8241663.7VSmg·L-15108172466.2153270.0140072.6TKNmg·L-17801957518576.316578.8TNmg·L-178048138.348038.547437.2NH3-Nmg·L-151012076.510579.47086.3NO3-Nmg·L-10375545NO2-Nmg·L-10249240280pH8.16.86.76.7　　,CODCr(SCOD)CODCr,SCODCODCr,,SCODCr。VSTS。。(TKN),TKNNH3-N。(38.3%～37.2%),NO2-NNO3-NSBR,。,SBR,,,。3.2　两级SBR污水处理性能及其与单级SBR的比较2　SBRSBR1(HRT1d)SBR2(HRT1d)%CODcrmg·L-1100001980137486.3SCODCrmg·L-129141457101465.2TSmg·L-166562436207668.8VSmg·L-151081724147271.2TKNmg·L-17801956092.3TNmg·L-178048143544.2NH3-Nmg·L-15101200100NO3-Nmg·L-1037195NO2-Nmg·L-10249180pH8.16.87.9　　3.1,10000mgLCODCr,SBR,1d。,3d,。,,3d,。,,,,。,SBR1SBR2SBR,,2。SBR1SBR21d,,SBR2d。212d3d,,SBR2dSBR24　　　200242023d。,,SBRSBR13,。,SBR2d,NH3-N0;SBR3d。SBRSBR。,,SBR,SBR。4　(1),10000mgLCODCr,1d(10gL·d)。NH3-N,3d。(2),SBRSBR。(),SBRSBR13;,SBRSBR。SBR2d,SBR3d。,,SBRSBR。(3),、、,,,,,SBR,SBR。1　HACH.HACHWaterAnalysisHandbook(2ndEdition).HACHCompany.Loveland,Colorado,USA.1992.2ProcessDesignManualforNitrogenControl,U.S.EnvironmentalProtectionAgency,Cincinati,Ohio.1993.3Shammas,N.Kh.Interactionoftemperature,pH,andbiomassonthenitrificationprocess.JournalofWPCF,1986.58(1):52～59.4　USEPA.Manual-NitrogenControl.U.S.EPAPublicationEPA625R-93010.OfficeofResearchandDevelopment,Washington,DC20460.1993.　,,19651,1998(),,,,。2001-09-22(55),,;ZnO,PbO,,。,。,,,。6　(1)。(2),1100℃,45min,0.5%,,。ZnO90%(92.52%),PbO5%;90%,96%,。(3),ZnO。1　,..,1997.19(2):131～133.2　..:,1994.　,,197410,1996,1999,,、,。2001-06-1825　　　20024202Abstract　ThreedegradablestrainsW1,W2,Y3isolatedfromcontaminatedsoilusingawastewaterfrompyrethroidandheterocyclicpesticidesproductsfactoryasasoleenergyandcarbonsource,weremixedandculturedtoobtainaLivingLiquorMicroorganisms(LLMO).Thebacteriaquicklyformedathinfilmonthecarriers.CODCrremovalratesof24.8%,43.5%and53.4%wereachievedundertheconditionof6810,3130and1890CODCrmgLfeed,respectively,aftertheoperationofa24-hperiod.Utilizinganadaptedactivatedsludgeasacontrol-experiment,theCODCrremovalratewasonly56.7%overthecourseof24-hofprocess,indicatingthatitispossibletotreatthissortofwastewaterbysomeeffectivemicrobialfilms.Keywords　degradablestrains,bacterialfilmsandpesticidewastewaterTREATMENTOFCATTLEWASTEWATERWITHSINGLESTAGEANDTWO-STAGESEQUENCINGBATCHREACTORLiXiujin(23)…………………………………………………………………………Abstract　ThecharacteristicsofSequencingBatchReactor(SBR)wasintroduced.Thewastewaterfromacattleranchwastreatedwiththesingle-stageandtwo-stageSBR,respectively.Itwasfoundthatthesingle-stageSBRwascapableofachievingsatisfactorycarbon,solidsandnitrogenremovalefficiencyandgoodeffluentquality.Buttwo-stageSBRprovedtobemoreeffectiveintermsoftreatmentefficiencyandammoniaconversionascomparedwithsingle-stageSBRsystem.Keywords　treatment,wastewater,cattleranchandsequencingbatchreactorTREATMENTOFFOODSTUFFFLAVORINGWASTEWATERBYABR-SBRPROCESSChengKaiyingetal(26)………………………………………………………………………………………………………………………Abstract　TheprocessofABR-SBRwasselectedtotreatfoodstuffflavoringwastewaterinlightofthecharacteristicsofitswastewaterquality.Theoperationresultsofthisengineeringprojectshowthattheprocessisreasonableandadvanced;thewaterqualityoftheeffluentcanmeetthefirst-orderof“SewageEmissionStandard”(GB8978-1996).Keywords　flavoringwastewater,ABRprocess,hydrolyticacidificationandSBRprocessRESEARCHONPROJECTOFTREATINGWOOLSPINNINGWASTEWATERBYMODIFIEDABPROCESSWuJixiuetal(28)………………………………………………………………………………………………………Abstract　Asystematicresearchonthetreatmentofwoolspinningwastewaterbyadsorption-biodegradation(AB)processwasconducted,andtechnicalmodificationsofpretreatmentandABphasewerealsomade.Theworkingprinciple,processflow,designparametersandbenefitofthisprocesswereanalyzedindetailaccordingtotheexampleoftreatingthewoolspinningwastewaterinNO.1WoolenMillofJiangsuJianluCompanyGroup.Keywords　woolspinningwastewater,ABprocess,engineeringexampleandresearchEXPERIMENTALRESEARCHONTHEGRAY-WATERTREATMENTBYMEMBRANEBIOLOGICALREACTORWenDonghuietal(30)……………………………………………………………………………Abstract　Gray-waterwastreatedbyMembraneBiologicalReactor(MBR).ThebiologicaltreatmentpartoftheMBRsystemwasbiologicalcontactoxidationprocess,andthemembraneseparationpartwashollowfiberUFmembrane.TheexperimentshowedthattheMBRsystemhadtheadvantagesofhighefficiencyandstableoperationinthetreatm
