ASMs中易生物降解有机物SS的物化测定方法周雪飞副本

　ASMs(SS)＊周雪飞　顾国维　　　通过研究提出一种快速确定进水溶解性COD中易生物降解部分SS的物理-化学方法。该方法以絮凝为主体,将可通过0.45μm滤膜的胶体物质进行絮凝沉淀,然后再辅以质量良好的滤膜过滤,二者结合可有效测定SS值。研究结果表明,絮凝方法和呼吸计量法所得出的结果具有较好的相关性,SS(OUR)约等于0.81SS(floc)。滤膜质量对测定结果影响很大,如果没有质量良好的滤膜,建议采用单一絮凝方法直接测定进水中的SS。　易生物降解有机物(SS)　城市污水　絮凝　活性污泥数学模型(ASMs)　膜过滤0　＊　(50138010)。(ActivatedSludgeModels,ASMs)(COD)、、,。,()、、。,ASMs,DHIEFOR、STOWASIMBA,。,,。ASMs,(SNH)(SS)。SNH,;SS,[1]。,ASMs,SS。1986,G.A.Ekama[2],SS,、。:,2～3d,(OxygenUti-lizationRate,OUR)SS。OURSS。,,SS,。,SS,,SS。,,,F/M、、,,。,SS,。,-。1　SS(VolatileFattyAcids,VFA),,,。SS,-,。:pH10.5,ZnSO4　Vol.29　No.11　200323　　　DOI:10.13789/j.cnki.wwe1964.2003.11.006,0.45μm,,,。ASMsSSCOD(1):SS=CODsol-SI(1)SS———COD;CODsol———COD;SI———COD。(1)CODsol,CODsolSS,SI。SI3dCOD[3]。(),,COD(flocCODsol)SI。,,,COD(flocCODsol)SI。SS。2　2.1　SS,SS[4～5],。(COD)。2.2　100mL1mL100g/L,1min,6mol/LNaOHpH10.5,,。,0.45μm,COD,CODCOD。COD。2.3　,SS0～200mg/L。1L。8h,,COD,,3d,COD,,SI。2.4　1。1.16L,,,、、。,20℃。,10～20mg/L(ATU),VSSVWW,DO,(OUR)。DO2mg/L,DO6mg/L,。1　OUR,2。XS。ΔDO,(2)SS。SS=VSS+VWWVWW×11-YH×ΔDO(2)YH,0.67gCOD/gCOD。3　3.1　24　　　　Vol.29　No.11　20032　OUR,3。,,SS(OUR)0.81SS(floc)。,XS;,,COD“”,。,,;,ASMsSS,SS,ASMs。　:SS(folc)SS,SS(OUR)SS。3　3.2　,COD200～500mg/L,,1。,+0.45μm,,COD,。,,COD“”,。,、,。,,COD。,,。1　　　123SSSISSSISSSI171561543819245+0.45μm153431384317651　:mg/L。4　COD-。:(1)COD[6]。(2)COD3dCOD3dCOD。。,,。,,+,COD“”,+CODsol,COD。,CODsol+0.45μmCOD。COD,。,SS,　Vol.29　No.11　200325　　　,。参考文献1　PJRoeleveld,MCMvanLoosdrecht.ExperiencewithguidelinesforwastewatercharacterizationintheNetherlands.WatSciTech,2002,45(6):77～872　GAEkama,PLDold,GVRMarais.Proceduresfordeterminingin-fluentCODfractionsandthemaximumspecificgrowthrateofhet-erotrophsinactivatedsludgesystems.WatSciTech,1986,18:91～1143　GAEkama,GVRMarais.Theorydesignandoperationofnutrientremovalactivatedsludgeprocesses.WRC,Pretoria,SouthAfrica,19844　PeterAVanrolleghem,HenriSpanjers,BrittaPetersen,etal.Esti-mating(combinationsof)ActivatedSludgeModelNO.1Parametersandcomponentsbyrespirometry.WatSciTech,1999,39(1):195～2145　HenriSpanjers,PeterVanrolleghem.Respirometryasatoolforrapidcharacterizationofwastewaterandactivatedsludge.WatSciTech,1995,31(2):105～1146　IWATaskGrouponMathematicalModelingforDesignandOpera-tionofBiologicalWastewaterTreatment.ActivatedSludgeModelsASM1,ASM2,ASM2DandASM3.IWAPublishing,England,2001◆:2000921239　:[phone]　E-mail:[e-mail]　:2003-7-25　＊高　洁　刘志雄　李碧清　　　在生物除铁除锰技术指导下设计建造的沈阳经济技术开发区供水厂,是我国第一座成规模的典型的地下水生物除铁除锰水厂。它的工艺特点体现在跌水弱曝气,在同一生物滤层中除铁除锰及培养期、稳定期的反冲洗机制。生物滤层培养成熟后,滤池铁锰去除效率达99%以上,出水水质优于国家标准,取得了稳定的运行效果。　生物除铁除锰　工艺设计　运行效果　　2080,,[1～2],“”,“”,,[3]。。,19997、,20015,200112,,0.05mg/L,(0.3＊　“”(96-909-01-02-04)。mg/L,0.1mg/L)。1　1.1　,,,,,:;;、。1.2　7.8hm2,:、。12m3/d,,6m3/d。,:2,10.5m;2,6;2;126　　　　Vol.29　No.11　2003WATER&WASTEWATERENGINEERINGVol.29No.11November2003ABSTRACTSCouplingTransformationsofIron-Manganese-PhosphorousinLowTurbidityDrinkingWaterResourcesYuanWenquanetal(10……………………………………………………………………………………………………)Abstract:ThecouplingtransformationrelationshipsamongFe,MnandPinalowturbidityreservoirwerestudiedbymeansofsite-monitoringanddatacorrelationanalysis.TheresultsindicatethattheconcentrationsofFeandMnandPaswellwillincreaseinalargescalewhenthermoclinelayerandanaerobiclayerformedinthereservoirinsummer.ConcentrationsofFe,MnandTPinthehypolimnionwere12.7,16.3and3.4timesgreaterthanthoseintheepilimnionrespectively.Correla-tionanalysisclearlydemonstratedthatthereareevidentcouplingrelationshipsamountFe,MnandPtransformation.Aconceptmodelofiron,manganeseandphosphoroustransformationinthisreservoirhasbeenestablished.InfluenceFactorsonFeRemovalfromUndergroundWaterinContact-OxidationProcessYuJianetal(15………………)Abstract:TheinfluencefactorsoftheDOlevel,filteringspeedandpHonFeremovalfromundergroundwaterinfiltercontact-oxidationprocessareresearchedexperimentally.TheFeremovalratesatdifferentpHlevelandfilteringdepthareobserved,andtheactivatedcoefficientβofFeremovalatconditionofpH6.55,8m/hfilteringspeedandDO6.5mg/Lhasbeendeduced.Physico-ChemicalExaminationofBio-Degradable(Ss)inActivatedSludgeModelsZhouXuefeietal(23…………………)Abstract:Aphysico-chemistrybasedfastmeasurementtodeterminethebio-degradablecontentofsolubleCODininletrawwastewaterhasbeenadvanced.FlocculentwasadoptedtodetermineSs,bythisway:the0.45μmpenetrat-ingcolloidswereflocculentlysettledandthenfinemembranefiltrated.ThedeterminedSsbyflociscorrelatedtothatbyrespirometry,about1Ss(respiratory)=0.81Ss(floc).Thequalityofthemembranecausestremendousinfluencetothedetermination.Incasewhennohighqualitymembraneobtained,itisproposedtoexaminetheSsbysingleflocculentway.TechnicalDesignandPerformanceofWaterworksforIronandManganeseRemovalbyMicroorganismGaoJieetal(26……)Abstract:Shenyangeconomicdevelopmentzonewaterworksisthefirstlarge-scalebiologicalundergroundwaterFe/Mnremovalfacilityinthiscountry.ByadoptedcascadeweakaerationallthefunctionsrelatedtoFe/Mnremovalsuchasthemicroorganismculturingandmaturing,steadyfilteringandbackwashingareprocessedinthesamefilteringbed.Whenthemicroorganismmaturing,asteadystatestableFe/Mnremovalratioexcess99%hasbeenobtained,whichisbetterthanthe
