高含盐量石油发酵工业废水处理研究杨健

··杨　健　王士芬　　　石油发酵工业废水中高含盐量对于生物处理有强抑制作用,本研究利用SBR活性污泥法对该类废水进行有机物降解试验,在废水中溶解性总固体浓度(TDS)50000mg/L～65000mg/L和CODCr浓度3000mg/L～6000mg/L范围内高含盐量对驯化后的耐盐活性污泥并无明显抑制作用,CODCr去除率稳定在90%以上,BOD5去除率稳定在95%以上,半速度常数Ks=340mg/L,最大比降解速度K=1.96d-1。驯化活性污泥以菌胶团和少量原生动物(裂口虫和漫游虫)为主,菌落形态相对较少。　驯化活性污泥　含盐量　生物降解　抑制作用　SBR反应器0　()。、,。,,。,,。[1～3]:1　CODCrBOD5TDSSO2-4Cl-Na+kTN/mg/L3000～60001650～330050000～6500020000～2500020000～2500010000～15000100～150(1);(2),,;(3),。,,。,。。,,、。:、、、、、、,1。1　1　1.1　1。　　1,BOD5/CODCr0.55,,,。　Vol.25　No.3　199935　　　DOI:10.13789/j.cnki.wwe1964.1999.03.012,TDS50000mg/L～65000mg/L,20000mg/L～25000mg/L,,,SBR。1.2　6.9LSBR,CODCr、BOD5、MLSSMLVSS。SBR,、、、、,(3h,2h)。SBR,,,。SBR,,。SBR,。1.3　3,2。2　/L/d/kgBOD5/(kgVSS·d)/mg/LCODCrBOD5TDSA6.90.10～0.251000～2500　550～13756000～30000B6.90.25～0.402500～40001375～220030000～40000C6.90.40～0.554000～55002200～302540000～650003　BOD5/mg/L　/mg/L　/%　/kg/(kg·d)CODCr/mg/L　/mg/L　/%　/kg/(kg·d)pH　　TDS＊/mg/L/℃VSS/mg/LABC17443495.50.12135310892.00.226.57.11172020290028643695.80.14156812492.10.246.07.220380212990312065095.90.19221417792.00.336.07.828780253100418077396.10.28334726892.00.506.57.431760213100519528495.70.30354927392.30.536.08.036150253100621379295.70.34395730092.50.616.07.5342902130107259011495.60.41470835892.40.716.07.4406002130508322513695.80.50591644492.50.896.07.8484002230809345414595.80.53628045892.70.946.07.864400223100　　:＊TDS1.4　:,,[4～6]。,。2。,,。,,1.0kgCODCr/(kgVSS·d),1。,。＊4×3=12h,2×3=6h。2　1.5　:;:;:;CODCr:;pH:pHS-3DC。2　SBR,CODCr80%～36　　　　Vol.25　No.3　199990%,,14d～18d。2.1　3。3,SBR(TDS11720mg/L～65000mg/L),CODCr90%,BOD595%;50000mg/L～65000mg/L,0.1kgCOD/(kgVSS·d)～1.0kgCOD/(kgVSS·d),,。3　2.2　3。3,-。,CODCr3340mg/L800mg/L;20hCODCr90%。,24hCODCr45.8%,CODCr,48hCODCr47.5%。,20h、,、;48h,,;72h,。:。2.3　,,、,;。4～6,,,SVI0.55～0.80,,;,,MLVSS/MLSS0.55～0.65。4。4　,,,、,、,。,106/mL～107/mL6.2×106/mL～3.9×107/mL　　、,。,。,(Am-phieptusSP.)(LitonotusSP.)。,:,;,。,,,,。,,。　Vol.25　No.3　199937　　　,,。。2.4　BOD5,4。:N=Q(S0-Se)/VX=(dS/dt)/X=KSe/Ks+Se(1)N———,kgBOD5/(kg　　MLVSS·d);Q———,L/d;S0———BOD5,mg/L;Se———BOD5,mg/L;V———,L;X———,mgVSS/L;K———,d-1;Ks———,mg/L。4　K=1.96d-1,Ks=340mg/L。K,Ks(1):N=1.96Se/340+Se(2)　　SeKs,(2)Se,(2):N=K·Se/Ks=5.76×10-3Se(3)　　(2)(3)。Ks340mg/L,Ks(25mg/L～100mg/L);K1.96,,。。3　(1)SBR,50000mg/L～65000mg/L,0.1kgCODCr/(kgVSS·d)～1.0kgCODCr/(kgVSS·d),,CODCr90%,BOD595%,。(2)。,。,。、、,65000mg/L(TDS)。(3)K(1.96d-1),Ks(340mg/L),。(4)SBR。参考文献1　HockenburyMRBursteinD&JambroESTotaldissolvedsolidsef-fectsonbiologicaltreatment,Presentedat32ndPurdueIndustrialWasteConference,19772　StewartMervinJ,LudwigHarveyF&KearnsWilliamH.JWatPol-lutControlFed,1962,34:1161～11773　LawtonGeraldW&EggertClarenceV.JWatPollutControlFed,1957,29:1228～12364　MillsEV&WheatlandAB.WatWasteTreat,1962(9):170～1725　MFHamoda&INSAl-AttarWatSciTechnol,1995,31(9):61～726　TokuzRY&EckenfelderWWJr.JWatRes,1979,13:99～104:200092　:[phone](O)　:1998-7-2338　　　　Vol.25　No.3　1999WATER&WASTEWATERENGINEERINGVol.25No.3March1999consistedofdepositedsolidsludgeanddissolvedorganicmatter,whichwererelatedtotheSSandorganicconcentrationsinthemixedliquorandsupernantofthereactorrespectively.ANewCarrouselOxidationDitchBaiXiaohuietal(27………………………………………………………………………)Abstract:Anewkindofcircularwrap-aroundoxidationditchhasbeendevelopedinNetherlandslately.Knowledgeonthetechnicalfeature,structureandcontroloftanks,layoutandoperationofthisfacilityisgiveninthispaper.Theadvantagesofthisprocesssuchassmallerlandrequirement,flexibleoperationandfineeffluentqualityareremarkable.InspectionandReconditionoftheWastewaterMarineDischargeinXinghuoDevelopmentZoneinShanghaiLiuChengetal(29………………………………………………………………………………………………………………)Abstract:TheinspectionandreconditionofthewastewatermarinedischargeinXinghuoDevelopmentZoneinShanghaiarepresented.Theexistingproblemstocausemalfunctionofthisengineeringarediscussedanditisrecognizedthattheoutfalldiffuserofmarinedischargehasbeenblockedbytheleavingsandrefuseinconstructionphase.Alsoitmustbeindicatedthattheconstructionsupervisionwillbeforcedforsimilarprojectstopreventtheunfavorableconse-quences.EnergySavingofWaterSupplyEnterprisesLuYun(31………………………………………………………………………)Abstract:Measurestoexecuteenergysavingcouldbeappliedintransformer,high-voltagemotorandpump-assem-bleorcarriedoutbyadoptingofInactivitycompensation,speedcontrolandeconomicalperformanceschemeinwatersupplysystem.Theeffectsofvariousmeasuresarediscussedanditissuggestedthatbestresultswillbeobtainedbyren-ovationofmechanicalandelectricalequipment,scientificselectionanddesignandtheoptimizationoftheperformancestatus.Alsothesuitabilityofvariousmeasuresisindicated.TreatmentofPetro-FermentationWastewaterwithHighSaltContentYangJianetal(35……………………………………)Abstract:ThemicrobialdegradationbySBRreactorswasinvestigatedtocharacterizethebiodegradabilityofahigh-salinityoilfermentationwastewaterwithTDSconcentrationof50000to65000mg/LandCODconcentrationof3000to6000mg/L;Theexperimentalresultsdemonstratedthatthehigh-salinitydidnotappeartobeinhibitorytotheaccli-matedculturethatcontainedmainlyflocculatedbacteriaandsomeofprotozoa(Amphieptussp.andLitonotussp.).Themicrobialdegradationres
