复合厌氧反应器的生产性快速启动研究陈业钢

复合厌氧反应器的生产性快速启动研究＊陈业钢　祁佩时　　　针对复合厌氧反应器处理高浓度难降解有机废水如何创造生产性快速启动条件及反应器的有效控制进行了相关研究。试验分别采用好氧青霉素发酵残渣和好氧活性污泥为接种污泥启动复合厌氧反应器,生产性中试规模50m3/d。试验表明,青霉素发酵残渣启动厌氧反应器在经济上和技术上都是可行的,启动周期短,试验系统表现出很好的生物降解性和抗冲击负荷能力。　复合厌氧反应器　快速启动　抗生素废水　青霉素发酵残渣　好氧活性污泥＊(Z99A11-4)。0　。,,,,,。[1]。,25000m3/d,COD3000mg/L;5000m3/d,COD8000mg/L。、、、、、、、。,、。[2～5],。,、,,180d,,。1　1.1　(1)1　1.2　,。2,1(S1/S2)2(Y1,Y2/Y3,Y4),。UASB,,,22.99m3,4.9m;,21.24m3,4.7m。,:31%,27%。,DN20、。。1.3　,。,,,()。　Vol.28　No.11　200245　　　DOI:10.13789/j.cnki.wwe1964.2002.11.015。[6～7],。。,,,,:、、、、、、、、、、。,。,2000,。,,,,,、、。1.4　。,,,,20m3。1。1,,,。1　/m3/dCOD/mg/LBOD/CODTN/mg/L503000～200000.4750～254TP/mg/LTSS/mg/LSO2-4/mg/L/℃10～110450～1500038～132510～251.5　,COD2000mg/L。,、,。,2℃,35℃。,。,,,Y1Y2()195mg/L,Y3Y4()1300mg/L。,,2～3,。200L/d,50%,。1.6　:COD,BOD,,SS,VSS,SO42-,pH,,,,。,,pH,,,。,700mg/L(CaCO3),pH6.5～7.5。2　,,COD3000～20000mg/L。S1,S2Y1Y4。2.1　。,,,,。2,3,4,S1,S2COD。S1COD17243mg/L,COD35%,16.84kgCOD/(m3·d);S2COD14203mg/L,COD32%,16.84kgCOD/(m3·d);,。,BOD/COD0.490.55,。,0.98m3/(m3·d),10kgCOD/(m3·d),46　　　　Vol.28　No.11　20022　S1COD3　S2COD4　COD,SS3000mg/L,S1,S2SS2000mg/L,,。,,。2.2　5,6,Y140d(NV2kgCOD/(m3·d)),COD60%;3kgCOD/(m3·d),COD70%;Y4,COD57%;3kgCOD/(m3·d),COD65%。,Y4Y1。5　Y1COD6　Y4CODCOD,,,;COD,COD,COD,Y4COD,,Y4Y1。Y4Y1,COD60%。,Y1,Y48.54kgCOD/(m3·d)11.56kgCOD/(m3·d)。,Y4,COD1000～2000mg/L,2000mg/L。,COD,,。2.3　,。,,Y114,40,40L/h;Y411,30,35L/h。Y1,Y4,(7)。7,Y1Y4,Y4。　Vol.28　No.11　200247　　　Y4Y1,,,。,,,。,Y1,Y41475L/(m3·d)1596L/(m3·d),0.320m3/kgCOD0.318m3/kgCOD。7　2.4　,,,,pH,SO42-,。,pH5,,pH4,。SO42-[8],SO42-[9],COD/SO42-5,SO42-4000mg/L[10]。,COD/SO42-3,SO42-1325mg/L,pH5,。8,9Y1,Y4SO42-,8,9SO42-90%。3　(1)、,。,,8　Y1SO42-9　Y4SO42-(),,,,。,,。,,。(2),;Y1,Y48.54kgCOD/(m3·d)11.56kgCOD/(m3·d),1475L/(m3·d)1596L/(m3·d),0.320m3/kgCOD0.318m3/kgCOD。(3),COD/SO42-3,SO42-1325mg/L,pH5,。参考文献1　,,..,1997,18(3):832　.“”.19973　LettingaG,HulshoffPolLW.UASB-processdesignforvarioustypesofwastewaters.WatSciTech,1991,24(8):87～10748　　　　Vol.28　No.11　20024　MichaelFTorpy.Anaerobictreatmentofindustrialwastewater.NoyesDataCorporation,USA,19885　,,..,2001,22(2):82～866　PWeiland,ARozzi.Thestart-up,operationandmonitoringofhigh-raceanaerobictreatmentsystems:discusser'sreport.WatSciTech,1991,24(8):257～2777　,,,.UASB.,1995,11(3):98　,,..,1994,16(3):89　JanDries,AndyDeSmul,etal.Highratebiologicaltreatmentofsul-fate-richwastewaterinanacetate-fedEGSBreactor.Biodegrada-tion,1998,2(9):103～11110,,..,1997,18(6):42:20023725865202　:(021)13817760356　E-mail:[e-mail]　　150090　:2002-3-1马　量　　　对扬子公司炼油厂软化水处理单元氢离子交换树脂被污染的原因、机理进行了分析和探讨,并指出了软化水装置安、稳、长、满、优运行和氢离子交换树脂复苏中需注意的问题。　氢床　钠床　离子交换树脂　污染　复苏1　H-Na(1),3(),3()。2000,5446mm,D116。2000,001×7,8000～10000m3。2,1994、1。1　-:(2mg/L),(≤1.5mmol/L,≤1.0mmol/L,≤0.25mmol/L)。pH,,。(≤0.03mmol/L,0.3～10mmol/L)。100m3/h,5m3/h,4t/h,95m3/h。2　199310,,,,1500～3000m3,,0.1MPa0.15～0.2MPa,,、、、、。,,,,、;286mg/L,。-1、-3　Vol.28　No.11　200249　　　WATER&WASTEWATERENGINEERINGVol.28No.11November2002thepipelinefeaturecurveofeachassembliesandamathematicalmodelundereveryoperatingstatusofthestation.Thismodelcouldbeusedfortheimprovementofpumpingassembliesandpracticalworkingstatuspredictionwithenoughaccuracy.ProteinFeedstuffExtractedfromFermentationMotherLiquidofMonosodiumGlutamateProductionMaiWenningetal(43………………………………………………………………………………………………………)Abstract:Intreatmentoffermentationmotherliquidofmonosodiumglutamatepreparationbycompositeprocessesofsodiumpoly-acrylateflocculationandairfloatation,85%and35%ofSSandCODrespectivelywereremoved,andatthesametime20.4kgofsomaticproteinfeedstuffwasextractedfrom1tonofmotherliquid.Bythiswaytheorganicloadingofsucceedingwastewatertreatmentwillbereduced.FastStartupofFullScaleComplexAnaerobicReactorChenYegangetal(45…………………………………………………)Abstract:Acomplexanaerobicreactortreatinghigh-concentratedantibioticwastewaterwasstudiedtofindouttheconditionoffaststartupandeffectivecontroloffull-scalefacility.Apilotplantwithcapacityof50cubicmetersperdaywasfedwithpenicillinfermentresidueinoculatedactivatedsludge.Theexperimentalresultsapprovedthatthepenicillinfermentresidueinoculationisfeasibleeconomicallyandtechnicallytoacceleratethestartupofthefacility.Excellentbio-logicaldegradationandresistancetoshock-loadinghavebeengained.WaterDemandAnalysisandForecastinginBeijingbyMultivariateLinearRegressionZhangYajunetal(53………………)Abstract:TheeffectivefactorsinfluencingthewaterdemandinBeijingareanalyzedqualitativelyandquantitativelybymultivariatelinearregressionprocessandthefinalforecastingfunctionofwaterdemandhasbeenestablished.Thewaterdemandof2020inBeijinghasbeenforecastedbythismodel.DesignofGasFireSystemFM-200forHeadquarterBuildingofBankofChinaZengJie(59…………………………………)Abstract:AFM-200GasFireSystemwasdesignedfortheHeadquarterBuildingofBankofChinainBeijingandpresentedindetailinthispaper.Techno-economiccompareandanalysisweredonefordecidingtoadoptFM-200.GasFireSysteminAirTrafficControlCenterQuXunetal(62………………………………………………………………)Abstract:Theperformancesoffivegasfiredistinctivesystemswerestudiedanddiscussed,andtwofirecontrolgases,IG541andheptafluoro-propane,arecompareddeeplywithfivemaininfluencefactors.Fu
