东深原水生物硝化工程试运行小结叶旭全

··叶旭全　谢汉强　张　辉　黄兴南　　　东深原水生物硝化工程采用生物接触氧化法对微污染原水进行处理,设计处理规模为400万m3/d。通过半年的试运行,可以初步认为,生物接触氧化工艺适于处理东深微污染原水,对氨氮去除率在75%以上,对其它10多项水质指标也有不同程度的降解,基本达到设计要求。　原水工程　微污染原水　生物接触氧化　试运行0　-、。19651998,108.35m3,27.52m3,。1　80,。90,,,,。,,。,,。1997、,,。199815,,19981228,、、。1　,400m3/d,46.3m3/s,24h,16.7m3/h。:,,,———,。(1)。316.5m×200m,6.33m2,,625m,27m,2.5‰,,,61m×10m。(2)。,188m,41m,60.2m,5,10m,6.5m。,46.64m19.0m。::55.40min;:39.3min;:3.8m;:3.0m;:1∶1。　Vol.26　No.2　20001　　　　DOI:10.13789/j.cnki.wwe1964.2000.02.0012　,,,:××=12.0m×25.0m×3.7m,20,6120,1400t。,YDT、,,,,、,YDT。,,71.1%,10.7m3。。,,,,250μm。,DN500.7m。200mm,100mm。ABS。HV-TURBO6KA44SV-GL225,550kW,555.6m3/min,63300kW。2　2.1　19981124,,1124121,,1226。121、,8,、DO、pH、NH3-N、NO-3-N、CODMn、SS、8。2.1.1　,。320m3/d(13.33m3/h)、,、,。19981212,。2.1.2　,,,。。,,,,、。2.1.3　,,。,6,,6。2　　　　　Vol.26　No.2　20002.1.3.1　1998121～27,13。1　NH3-N/dNH3-N/%/dNH3-N/%/dNH3-N/%10.351011.881943.0820.991110.642042.5830.331212.982141.9840.001314.002242.4350.001416.92358.362.81521.182444.472.211620.282563.1581.011714.492664.0294.731829.272774.073　NH3-N　　3,,,,,;10d,,;,,20%,,,,84%,74.07%。,,。2.1.3.2　,1998121～28(24),。2,,,,,。2　NO-3-N/dNO-3-N/mg/L/dNO-3-N/mg/L/dNO-3-N/mg/L10.006110.191210.73020.010120.163221.07530.008130.213231.10040.009140.204241.52750.005150.327251.91460.005160.357261.97070.005170.730272.10480.007180.728282.58590.014190.767100.095200.7164　NO-3-N2.1.3.3　、DOpH、,、DOpH(56)。5　DO6　pH5,,16℃,,,,,DO。,,　Vol.26　No.2　20003　　　　DO。6,,,,pH。2.1.3.4　,,,7。7　7,,322℃,420.6℃,,1015.3℃,17,,,,。,。,,,。,,,,,,、、,。。,、,,。2.2　,。,,。19996,7.076m3,475.4m3,,90.1%,1237.64t,10.96t。,。2.2.1　(1),6。(2),6。(3),15～20cm,。(4)。,,,,,,,,;,,,,。(5)、,。,,,。19994～5,,5。2.2.2　,,,,,。,,,,。,,,,。3,199812,,;5,,;6。3,,,,,,。2.2.3　4　　　　　Vol.26　No.2　20003　NH3-N1998199912123456/m310172.59768.18848.011552.210591.510589.69228.1/t84.75163.85170.45243.63216.16137.76221.04/kg2734479560877859720544447063.6/kg83637560760998668837896210956.0/%30.464.480.171.066.233.961.1/%74.183.590.185.085.063.483.04　NO-3-N/mg/L19981999121234560.6861.2460.7380.6510.7631.2380.9751.492.9752.6422.9152.9522.5783.392NO-3-N0.8041.7291.9042.2642.1891.342.42　　3、4,19992、380.1%71.0%,2.64mg/L2.915mg/L。2.2.4　,,5。5,1∶1,,。3　,:,。,,、、CODMn、、、、、10。,,。5　1998199912123456DO/mg/L3.964.144.163.402.882.222.13DO/mg/L9.288.517.287.707.007.646.40/m3362.8336.6360.3359.8342.5363.0435.1/m3328.2315.1316.0372.7353.1341.6308.01.131.141.170.980.981.111.45　　,。,,。,,,,。★:518021-　:[phone]　:1999-10-28　Vol.26　No.2　20005　　　　WATER&WASTEWATERENGINEERINGVol.26No.2February2000CONTENTSCommissioningOperationofBiologicalNitrificationProcessofDongjiangRawWaterTreatmentYeXuquanetal(1……)Abstract:TheslightlypollutedrawwaterofDongjiang-Shenzhendivertingcanalistreatedbybiologicaldenitrifica-tionprocessnamelybiologicalcontactoxidationwithdesigncapacityof4millioncubicmetersperday.Throughhalfyearofcommissioningoperationaremovalratioupto75%ammonianitrogen,andalsodifferentlevelsofdegradationforoth-ertenindicatorshavebeenobtained.Theexpectedtargetindesignstagehasbeencompleted.Itisbelievedthatthisprocessissuitablefortherawwaterinthiscase.OperationofA2/OProcessinBaodingMunicipalWastewaterTreatmentPlantTongEncongetal(6………………………)Abstract:TheoperatingstatusandprocesssettingoftheA2/OprocesstoremovephosphorusinBaodingMunicipalWastewaterTreatmentPlantarepresented.Theproblemsariseninbiologicalphosphorusremovalprocessarediscussedandtheseshallbehelpfultofurtherexplorethepracticalmethodsandmeasurestoimprovethephosphorusremoval.ApplicationofABProcessinMunicipalWastewaterTreatmentZhengQin(9………………………………………………)Abstract:TheprocessschemeandperformanceofaGermanwastewatertreatmentplantinamedium-sizedcityFrefeld,Nordrein-Westfalenarepresentedinthispaper.FormationandControlofFoaminActivatedSludgeProcessDingFengetal(13……………………………………………)Abstract:Theresearchesontheformationmechanism,influencefactorandhazardsoffoamprobleminactivatedsludgeprocesshaveshown,thatitismainlycausedbyexcessgrowthofNocardiaamarae,Nocardiapinensis,MicrothrixparvicellaandActinomycetesandintentlyrelatedtothecircumstancefactorssuchasthetemperature,pHvalue,F/Mratio,thekindsofbenthonicsubstancesandtheoperatingconditionsoftheactivatedsludgesystem.ThefoamcontrolmeasuresliketheMCRTcontrolandbio-selection,SFWtechnology,classifiedselectorandchemicaldosagehavebeendevelopedonthebasisofkineticofactivatedsludgeandthetheoryandpracticeofsludgebulking.StudyonOperatingParametersofAerationTankinAerobicSelectorProcessLiCaibinetal(17……………………………)Abstract:Thisresearchcomparedtheinfluenceofaerationtankoperationparameterssuchashydraulicretentiontime(HRT),sludgeretentiontime(SRT)etc.inaerobicbiologicalselectoronCODremovalefficiency,sludgesettlea-bilitywiththatinthecompletemix-activatedsludgeprocess(CMAS).Researchontheworkingmechanismofaerobicbiologicalselectorwasdonethroughsludgeabsorptiontestofsolubleorganicmatterandkineticparametersanalysis.Toattainthesameeffluentquality,SRTandHRTfortheaerobicbiologicalselectorprocessareshorterthanthatforCMASprocess.AerobicselectorprocesscancontrolfilamentousbulkingefficientlyunderlowF/Mcondition.Butithasafail-uretende
