废水回用工艺中曝气生物滤池的特性研究张树德

张树德1　郎华伟2　吴百春1(1.中国石油集团安全环保技术研究院;2.河北理工大学建筑工程学院)　　　　以页岩陶粒为滤料,对曝气生物滤池的运行性能进行了研究。通过考察水力负荷对COD、氨氮去除效果的影响试验,容积负荷对COD去除效果试验,BAF对浊度的去除效果、抗冲击能力试验;结果显示:COD最佳水力负荷为7.0m3/h,NH4+-N最佳水力负荷为5.0m3/h,COD最佳容积负荷为5.89kg/(m3·d);进水浊度平均为12.7NTU,出水浊度平均为3.5NTU时,平均去除率为72.4%。水力冲击负荷对硝化菌的影响较小,而对异养菌影响较大。　　　废水回用　曝气生物滤池　水力负荷　COD　氨氮　去除0　　　　,。(BiologicalAeratedFilter,BAF),[1-5]。,。,,,。,BAF,,。1　　　4DN200×3000mm,100mm;,2.5～5.0mm。,,12～28℃;pH7.02～8.50。1。　　,,,48～120h。1　mg/LCOD27.9～122.498.07～57.6617.20～60.120～7.340～1.291.10～2.53　　:、(DO)、pH、、CODCr、NH4+-N、NO2--N、NO3--NSS。。2　2.1水力负荷对COD去除效果的影响1.0、2.0、3.0、5.0、7.0、9.0、10.0m3/h,2,CODCr。COD1。1,CODCr。,CODCr,7.0m3/h。,47.72%14.49%。　　:,,2006,,,,。:8,100083·36·　　　2009年9月　　　　　　　　　油气田环境保护　　　　　　　　　　1　COD,,,,。,,,,。,,,;,,,。,,,,。2.2容积负荷对COD去除效果的影响COD2。2　COD　　2,COD,5.89kgCOD/m3·d,44.84%,,9.01kgCOD/m3·d,COD14.49%。:,,,,。,,,。,,,,。2.3水力负荷对氨氮去除效果的影响。3,。,,,,,,,。,,。NH4+-N5.0m3/h。3　2.4BAF对浊度的去除效果7m3/h、3∶1,4。4　　　,12.7NTU,3.5NTU,72.4%。,5NTU,GB/T18920-2002《》23.2NTU,6.5NTU,71.98%,。:◇。,·37·　　　　　　　油气田环境保护　　　　　　　　第19卷·第3期　　　,。◇、。,,,,。◇。[6],,、、、、。,,,,。2.5BAF抗冲击能力试验:,。,。5.0m/h15.0m/h9min,CODCr、NH4+-N,。5　CODCr、NH4+-N　　5,0.5h,CODCr43.16%21.66%,;NH4+-N68.63%51.85%,1.5h35.46%,CODCr1.0h。,CODCr2.5h,3.5h,45%,。NH4+-N,6.0h。,,,[7],,。,,。,NH4+-NCODCr。,,,,。3　　◇BAFCODCr、,,CODCr,,,7.0m3/h,5.89kg/(m3·d)。◇BAFNH4+-N,。◇BAF,,。,CODCr2.5h,3.5h,45%。NH4+-N,6.0h。[1]　,.[M].:,1999.[2]　AmarD,PartosJ.Theuseofanupflowfixedbedreactorfortreatmentofaprimarysettleddomesticsewage.WatRes,1986,20(1):9-14.[3]　,,..,1998,14(1):18-20.[4]　.().:.[5]　.[D].,2003,6.[6]　,,..:,2000.[7]　.[D].,2005.(收稿日期　2009-04-01)(编辑　　李娟)·38·　　　2009年9月　　　　　　　　　油气田环境保护　　　　　　　　　　acclimationstagestartedwhenthesludgecontentincreasedto2000～3000mg/L;theoperationdatashouldbewellcontrolled,suchaspH,alkalinity,salt,nitrogen,sludgeage,sludgeindex,etc,thenwecouldregulatethedirectionofbiologicaloxygenation,andgetthepurposeofsludgeculture.KEYWORDS　DalianPetrochemicalCompany;A/Obiochemicalpond;inoculation;microbecultureandacclimationApplicationofModifiedFiberBallinOilfieldWastewaterTreatment(22)HuangCheng1　WangMei1　XiaYinxuan2　ZhangYongqiang3(1.ShanshanProductionPlantTuhaOilfieldCompany;2.PetroChinaTuhaOilfieldCompany;3WenmiProductionPlantTuhaOilfieldCompany)ABSTRACT　Filtrationbyfiberballcangivefullplaytosewageinterceptioncapacityofdeepfiltermaterial.Thepaperintroducedtechnicalrequirementsofmodifiedfiberball,mainproblemsinthecourseofusing,structureandcharacteristicsoffiber,andfieldapplicationsinoilfieldwastewatertreatment.Theexperimentsshowedthatafterwashingby50%mutualsolventand2%surfactantand2%causticsoda,thecolorofmodifiedfiberballturnedgreyishwhite,anditsfiberbecameloose.Thecleaningwasrelativelycomplete,withnostickingphenomenon.KEYWORDS　TuhaOilfield;modifiedfiberball;filtration;wastewatertreatment;applicationResearchandApplicationonImprovingtheTechnologyofHeavyOilDehydrationinHenanOilfield(25)OuHua　LiuXiaohui　MaRongchao(JinglouOilFieldofSINOPEC,Henan)ABSTRACT　Selectingefficientdemulsifier,usingmorereasonableandeffectivewaytoadddrugs,improvingdehydrationeffect,andreducingproductioncostareveryimportant.JinglouoilfieldofSINOPECchoseefficientdemulsifierforheavyoilanddrewtheconclusionthroughtheapplicationofpipelinedemulsifiesthatFS-21ⅡdemulsifierhadmuchbettereffectsindehydrationthanFS-21Ⅰ,andthewatercontentofcrudeoilwasmuchlower;addingdrugsoutofstationhadmuchbettereffectsthaninstationandneededlessdose;theapplicabilityofFS-21Ⅱdemulsifierwasgood,whichimprovedthewholedehydrationeffectofheavyoilandgotobviouseconomicbenefits.KEYWORDS　Jinglouoilfield;heavyoil;dehydration;demulsifier;instation;outofstation;pipelinedemulsificationTechnologyApplicationofWasteDrillingFluidTreatmentinChangqingLowPermeabilityOilfield(28)JiZhonglun　ZhouLihui　RenJianke　ZhangHailing(Oil&GasTechnologyResearchInstituteChangqingOilfieldCompany)ABSTRACT　Bytheperformanceanalysisoflowpermeabilityoilfieldwastedrillingfluid,theintegrativetechniqueofthesolid-liquidseparation-solidificationwasindentified.Itwasanalyzedhowdifferentsystemsanddosageofgelbreakerandflocculantmolecularweightaffectedthesolid-liquidseparationandtheseparatedwater.Theresultsshowedthatthepenetrationindexofsolidificationbodywouldbelessthan0.5mmwithadding20%nativeclayand6%firmingagentsatthesametime,whichmetthestrengthrequirementswithlowcosts.ItwasprovedbythefieldtestthattheseparatedwaterandthelixiviumofsolidificationbodymeetthestandardⅡofIntegratedWastewaterDischargeStandard(GB8978-1996).KEYWORDS　ChangqingOilfield;lowpermeabilityOilfield;wastedrillingfluid;solid-liquidseparation;solidificationResearchonCharacteristicsofOilySludgeinXinjiangOilfield(31)HeHao　WangAijun　ZhangZhiqing　FuLei(PetroChinaXinjiangOilfieldSurveyandDesignInstitute)ABSTRACT　Oilysludgewasoneofmainpollutionsourceofoilfieldproduction.Oilsludgefromthecrudeoiltreatmentsystemwasanalyzedinphysical&chemicalproperties.Theresultsshowedthatplantnutrientcontentwaslowinoilysludge;theheavymetalscontentwaslowerthanthestandardofControlStandardsforPollutantsinSludgefromAgriculturalUse(GB4284-84);Allgeneralcharacteristicsofoilysludg
