高浓度有机废水大型厌氧反应器的调试和起动运行李锡英

李锡英　刘　戈　杨沂凤(,330029)　介绍了高浓度有机废水大型厌氧反应器的调试和起动运行的全过程。采用处理同类废水中温发酵的厌氧污泥作种泥,满罐低浓度接种。通过逐步提高负荷和升温,培养和驯化出足够数量高温发酵的活性污泥,60d以内就能正常生产运行,达到设计所预期的目标。较常规起动方法可缩短时间1倍以上。　大型厌氧反应器　高浓度有机废水　调试　起动运行1　,。、、、CODCr90%,———。1t500m3,CODCr4×104～5×104mgL,SS2.5×104mgL。CODCr3×103mgL,SS2.5×103mgL,6×103m360%。,。,。2　,。(USR)(SSB)21,USR,。(CODCr)(SS)。:(1)50d,,,,,,CODCr92%。(2),,,SS88%。CODCrSS,,,,。3　t,2,。1500m3,2,USR,,1000m3;SSB,、。,:(1),;(2),;(3)USRSSBUSR,();(4);(5)。4　、、、。,。,,1000m3,。4.1　复合厌氧反应器试水试压检漏和联动试机,;;32　　　20024202DOI:10.13205/j.hjgc.2002.02.011。,——————,24h,,,2,24h,,5%。,USR,,、、、,,。4.2　接种、启动,35℃,。、35℃,SS1.2×104mgL,pH7.6,90m3。20m3,,2d,,3～5d,。4.3　污泥培养,,,。CODCr7kgm3,0.5kgm3·d,--,5,2m3,。,,0.5～1kgm·d。:(1)pH。、、pH,pH6.8～7.8。(2)CODCr。CODCr80%,60%。(3)。,1～1.5℃,55℃。(4)pH。CODCr,,50%。4.4　稳态运行50d,,,20,18～20m3。3m30kgm,55±2℃,CODCr90%,4～6m3m3·d,60%,。5000～6000m3。5　(1),,。,。(2),,。(3),,0.5～1kgm3·d。(4)、,55℃。(5)pH、CODCr。,、,60d,1。1　..:,1998.2　..,1999.17(1).3　..,2000.20(1).　,,194610,1968,。,、,、。2001-09-2133　　　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.TheexperimentshowedthattheMBRsystemhadtheadvantagesofhighefficiencyandstableoperationinthetreatmentofgray-water.Underthetestconditions,theeffluentcouldmeettheStandardofGray-WaterQuality(CJ25.1-89).Keywords　membranebiologicalreactorandgray-waterDEBUGGINGANDSTARTINGOPERATIONOFALARGEANAEROBICREACTORFORHIGHCONCENTRATIONORGANICWASTEWATERLiXiyingetal(32)………………………………………………Abstract　Thefullprocessofdebuggingandstartingoperationofalargeanaerobicreactorforhighconcentrationorganicwastewaterispresentedinthispaper.Amediumtemperaturefermentedanaerobicsludgebytreatingthesamesortwastewaterisused,andseedingoffullpotandlowconcentrationisalsoadopted.Loadandtemperaturearegraduallyraised.Enoughhotfermentedactivesludgeiscultivated.Thesystemcanoperatenormallyaftertwomonths,andcostslesstimethantheordinarystartingmethod.3ENVIRONMENTALENGINEERINGVol.20,No.2,April,2002Keywords　highconcentrationorganicwastewater,largeanaerobicreactor,debuggingandstartingoperationAPPLICATIONOFMOSSBAUERSPECTROCOPYINTHEEXPERIMENTOFCOALDESULFURIZATIONBYMICROWAVERADIATIONChengRongetal(34)……………………………………Abstract　ThispaperpresentstheanalysistotheexperimentofcoaldesulfurizationbymicrowaveradiationwithMossbauerSpectroscopy.Bycontrastwiththeradiatedsampleandtheoriginalsample,dataindicatesthattheisomericshift(IS)andthespectraarea(A)decreaseandthemagnetichyperfinesplittingoccurs,whichshowsthetransformationofpyritetopyrrhotite.O
