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:cyg6910@sina.com  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
