碟管式反渗透高浓度废水处理技术　关键字：碟管式  反渗透  高浓度废水  处理技术  1碟管式反渗透的核心——膜柱简介碟管式膜系统的核心是由碟片式膜片、导流盘、O型橡胶垫圈、中心拉杆和耐压套管所组成的膜柱。碟管式膜柱有大膜柱和小膜柱两种。小膜柱直径为200毫米，长1000毫米，有170个导流盘和169个膜片；大膜柱直径为214毫米，长1400毫米，由210个导流盘和209个膜片构成。膜片和导流盘间隔叠放，O型橡胶垫圈放在导流盘两面的凹槽内，用中心拉杆穿在一起，置入耐压套管中，两端用金属端板密封。2DT－RO技术特点与其他膜组件（卷式封装）相比，碟管式反渗透具有以下三个明显的特点：通道宽：膜片之间的通道为6mm，而卷式封装的膜组件只有0.2mm；流程短：液体在膜表面的流程仅7cm，而卷式封装的膜组件为100cm；湍流行：由于高压的作用，渗滤液打导导流盘上的凸点后形成高速湍流，这种湍流的冲刷下，膜表面不易沉降污染物。在卷式封装的膜组件中，网状支架会截留污染物，造成静水区从而带来膜片的污染。以上三个特点，决定了碟管式反渗透技术在处理渗滤液时可以容忍较高的悬浮物和SDI，通俗一点讲，就是不会堵塞。同时，这三个技术特点体现在具体实践中，使碟管式膜技术有如下几个工程特点：1）膜组的结垢少，膜污染轻，膜寿命长DT-RO的特殊结构及水力学设计使膜组易于清洗，避免了结垢和其他膜污染，从而延长了膜片寿命。用于DT-RO的膜片寿命可长达2年以上，甚至更长。n2）不依赖于预处理，具有良好的稳定性、安全性和适应性由于DTRO膜组具有特殊的水力学设计，DTRO膜组不用预处理可以直接处理渗滤液，使之适于处理高浑浊度和含砂系数高的废水。对于一般的反渗透系统，进入膜组的废水浑浊度不能超过1，含砂系数不能超过3。为使进水达到上述指标，往往需要比较复杂的前过滤和化学处理。由于DTRO膜片和导流盘之间有比较宽敞的通道，进入膜组的废水浑浊度可达到4，而含砂系数也可达到40。这样，只需要简单的砂滤器和精滤器就能满足膜组系统的要求。在具体工程中，预处理系统可有可无。对于有预处理的系统，无论预处理环结是否高效、稳定，反渗透系统都可以稳定的达标出水。同时由于不依赖于生物处理，碟管式反渗透对填埋场各个阶段的渗滤液具有良好的适应性。3）具有十分可靠的处理效果到目前为止，国外十几年来243个渗滤液处理工程实例无一例失败。碟管式反渗透设备在国内十余个垃圾厂的处理实例，无一例因堵塞导致效果受影响。4）安装、维修简单，操作方便，自动化程度高由于DTRO系统采用的管道、零备件大多是标准件，安装、维修比较方便。同时，系统内的膜片可以单独抽换，不像卷式膜或中空纤维膜那样，只要一处膜片损坏，就得更换整个膜柱，这样就降低了DTRO系统的维护费用。该系统所有操作由计算机控制，具有先进的自动检测和显示系统，自动化程度高，操作方便。·AllIndustrialMarkets·Aerospace,Defense,Marine·FuelsandChemicals·GraphicArts·IndustrialManufacturing·Microelectronics·OEMMedia,MembranesandMaterials·PowerGeneration·Transportation·WaterTreatmentLIFESCIENCESMARKETS·AllLifeSciencesMarkets·AnimalHealth·Biopharmaceuticals·ConsumerWater·FoodandBeverage·Laboratory·Medical·OEMMaterialsandDevicesABOUTPALL·AboutPall·InvestorRelations·CorporateSustainability·QualityatPall·CorporatePublications·Newsroom·Careers·IndustryEvents·ContactUs> ProductsSortedByMarket/Application  ALLPALLPRODUCTS   INDUSTRIAL   LIFESCIENCES 窗体顶端SelectProductTypeSelectProductName(A-Z)SelectMarket/ApplicationProductsonthiswebsitemaynotbelicensedinaccordancewithCanadianlawforsaleinCanada.PleasecheckwiththelocalPallofficeforavailability.TermsandConditionsofSaleAccessoriesandComponentsAirCleanerAssembliesBiochemicalsBloodFiltersandSetsCapsulesCartridgesandElementsCentrifugalDevicesChromatographyProductsCoalescersandSeparatorsConnectorsConsumerWaternDepthFilterModulesFilterFunnelsFilterHoldersFilterPlatesHousingsIVandSolutionFiltersImmobilizedCanisterInfusionFiltersIntegrityTestInstrumentationLaboratoryAccessoriesManifoldsMedia,MembranesandMaterialsCastFilmCeramicMediaChromatographyMembranes/Sorbents/Resins/GelsDiagnostic/TransferandDetectionMediaFibrousMediaGlassFiberMediaMetalMediaMicroporousMembranesSinteredMediaUltrafiltrationMembranesMedicalComponentsandSolutionsMedicalGasApplicationsMicrofiltrationModulesPumpsPurifiersPurifiersandWaterRemovalProductsRespiratoryandAnesthesiaProductsReverseOsmosisModulesServicesSheetFiltersandSheetFilterModulesSingleUseSystemsSurgicalSmokeFiltrationSyringeFiltersSyringeFilters/PharmacySystems(Biopharmaceutical)Systems(FoodandBeverage)Systems(Industrial)TangentialFlow/CrossflowProductsTestingandMonitoringProductsTrampOilRemovalUltrafiltrationModulesValvesVentFiltersandRespiratoryCircuitsforPatientCareVentFiltersforIndustrialandEquipmentApplicationsWaterFilters/Point-of-UseandIn-lineWaterFilters/Pre-filtrationWaterFilters/TrackingSystemWaterPurificationSystemsHOMECONTACTUS窗体顶端n窗体底端·AboutPall·InvestorRelations·CorporateSustainability·QualityatPall·CorporatePublications·Newsroom·Careers·IndustryEvents·ContactUsIndustrialIndustrialMarketsandCapabilitiesAEROSPACE,DEFENSE,MARINECommercialAircraftHelicoptersMilitaryAircraftMilitaryVehiclesShipsSpaceVehiclesWaterPurificationTreatmentFUELSANDCHEMICALSChemicalProducersOEMMedia,Membranes,andMaterialsOilandGasOilSandsPolymerProcessorsRefineriesGRAPHICARTSFountainSolutionClarificationInkJetFiltrationPrintingandPublishingSpecialtyCoatingsINDUSTRIALMANUFACTURINGAutomotiveMiningMobileEquipmentOEMOEMMedia,Membranes,andMaterialsPrimaryMetalsPulpandPaperMICROELECTRONICSDataStorageDisplayGraphicArtsMultilayerCeramicCapacitorsOEMMedia,Membranes,andMaterialsPhotovoltaicsSemiconductorOEMMEDIA,MEMBRANESANDMATERIALSPOWERGENERATIONCoalPulverizersEmissionsandEnvironmentalMonitoringSolutionsFossilEnergyHydroelectricTurbinesNuclearPowerSolutionsOEMMedia,Membranes,andMaterialsWindEnergyTRANSPORTATIONMobileEquipmentOEMPowertrainRailTestandValidationWATERTREATMENTMunicipalWaterDesalinationIndustrialWaterStilllookingforwhatyouneed? ClickHere©Copyright2011PallCorporation.Allrightsreserved.HOMECONTACTUS窗体顶端n窗体底端FINDPRODUCTS·AllPallProducts·AllIndustrialProducts·LifeSciencesProducts·ProductsSortedByProductName(A-Z)·ProductsSortedByMarket/ApplicationINDUSTRIALMARKETS·AllIndustrialMarkets·Aerospace,Defense,Marine·FuelsandChemicals·GraphicArts·IndustrialManufacturing·Microelectronics·OEMMedia,MembranesandMaterials·PowerGeneration·Transportation·WaterTreatmentLIFESCIENCESMARKETS·AllLifeSciencesMarkets·AnimalHealth·Biopharmaceuticals·ConsumerWater·FoodandBeverage·Laboratory·Medical·OEMMaterialsandDevicesABOUTPALL·AboutPall·InvestorRelations·CorporateSustainability·QualityatPall
