城市污水处理与一体化氧化沟技术邓荣森

邓荣森　许俊仪　谭显春　　　纵观百年城市污水处理技术的发展,通过对近年来污水处理新技术和运行方式的分析,提出现代污水处理技术发展总趋势是缩短和简化工艺流程,并对污水处理一体化技术作出分析和讨论,提出一体化氧化沟技术不同之处是不作时间和空间调配。一体化氧化沟单空间连续工作,容积利用率高,有较好的发展前景。　城市污水　一体化　氧化沟　时间　空间0　,,,。,。,,,,,。,,20。50Pasveer。:;、、4。,,BOD、SS,N、P,,、、。,,SBRUnitank、CASS、A2/O、A/O。,。1　(OxidationDitch),(ContinuousLoopReactor),。1920,Sheffield。(TNO)50(Voorschoten)。、。。,。,,;,。,,,。,。,4:Pasveer,(607m3),(C、N、PC.2000)。2　2.1　,。,70,,28　　　　Vol.26　No.11　2000DOI:10.13789/j.cnki.wwe1964.2000.11.010。,。20,,SBRICEAS、AB、、A/OA2/O,,。AB(Adsorption-Biodegradation),70,AB。SBR,,20。、、,。A/OA2/O,,、,BOD,。,()。2.2　。;。,、,,N、P,,。,。:,,,。,:,,。,。SBR、CASTUnitank。,,D(),VR、TDSS()。,,()。BMTS、BOAT、。,。,,,。3　,,,。,,,,,、SBRUnitank。,Unitank“”,(AF)(1),SBR“”,(fa)(2):SRT=XVΔX·AF,AF1(1)SRT=(VX)TfaQwXr,fa1(2)X———,mg/L;V———,m3;ΔX———,kg/d;Qw———,m3/d;Xr———,mg/L。AFfa,　Vol.26　No.11　200029　　　。,,,,,。,1/10。58%(fa=(3+8+3)/(8+8+8)×100%),,0.40。37.5%(fa=(3+3)/(8+8)×100%)。,。SBR,。,,。:(1),,,SRT,。(2),,。,。ICEAS,,50%。,。(3),,,,。4　4.1　(CombinedOxidationDitches),、、,。Pasveer1954Voorschoten,360,,。80。,,,100%。,,:、。:(1),,、,,、、、。(2),BOD5SS90%～95%,COD85%,。(3),,,,。(4),,,。(5),,。(6),。4.2　,。1987,92,(UnitedIndustriesInc.)(BOAT),ArmcoBMTS,EIMCOCarrousel,(Lakeside)Lightnin,Envirex。4.3　,10000m3/d,1。　　10.5m,4.5m,30　　　　Vol.26　No.11　2000陈义标　　　在分析实际供水情况的基础上,认为在规划年限内以最高日最高时作为水厂和管网设计流量存在不经济的问题,提出了在不同供水阶段,采用不同设计流量的建议。　供水系统　给水厂　供水管网　设计流量。1000mm,9m2,45kW;7.5kW2。,。,0.75kW1,2.2kW1。,15000m3/d,VR。。:1m3600～800,0.20～0.25kW·h,0.3～0.5m2。4.4　,,,,,、、、,。。,。参考文献1　..,1999,25(3):12～152　,...1998,10:281～2843　.(Unitank).,1998,24(11):16～194　,.(CASS).,1999,25(11):5～85　,,..,2000,26(3):19～216　CFForster.ThehistoricaldevelopmentofOxidationditch.Oxida-tionditchesinWastewaterTreatment.chapter1⊙:400045　:[phone](O)　68704247(H)　:2000-4-130　,:。,,、。,。,,,;。,。,,;,,,60%～70%。,,,,、、,。,,、,,,;,。　Vol.26　No.11　200031　　　WATER&WASTEWATERENGINEERINGVol.26No.11November2000CONTENTSDeterminationofAssimilableOrganicCarboninDrinkingWaterLiuWenjunetal(1………………………………………)Abstract:ThreemethodsofP17andNoxcultureinoculationtoexaminetheAssimilativeOrganicCarbon(AOC)indrinkingwaterarecompared,includingtheirpropertiesandessentialeffectsofexaminationconditions.Thecompara-blepropertyoftheexaminationresultsofdifferentwatersamplesispoorforthefirstmethod,becauseitisinoculatedin-dividually;thecommonmatrixforbothP17andNoxwascalculatedrepeatedly,soitisunsuitableforapplication.Boththesecond(simultaneousinoculation)andthird(ordinalinoculation)methodsaresuitablebytheirexclusivestrongpoints.TheobtainedyieldcoefficientsofP17andNoxinsodiumacetatesolutionbytheexperimentare1.4×107and1.8×107cfu/μgofcarbonacetateforP17andNoxrespectivelyhigherthanthatgivenbyVanderKooijevidently.ProcessDesignofMSBRWastewaterSystemZhaoZhongfuetal(6…………………………………………………………)Abstract:TheprocessdesignofaMSBRsystemintheYantianWTPinShenzhencity,GuangdongProv.ispre-sented.Thedesignsize,functions,operatingparameters,selectionofequipmentandfeatureofthetechnologyprocessaredescribedindetails.ResearchonthePressurizedAerationandSBRActivatedSludgeProcessChenLiboetal(9…………………………………)Abstract:ApressurizedaerationandSBRactivatedsludgeprocessispresented.Ithasadvantagesofhighvolumet-ricloading(0.8-1.0kgCOD/(m3·h)),highspeedofdegradationandhighrateofNremoval.ItmightbesuitabletotreathighormediumlevelorganicespeciallyN-containedwastewater.StudyonStartUpofVariableRateBiofilterwithEnzymaticPackageLongTengruietal(12………………………………)Abstract:Thestartupofavariableratebiofilterwithenzymaticpackagewasresearched.Especiallythesludgeinoculation,thearrangementofpulseon,theorganicloadingandtheeffectofinflowwastewaterontheinitialperfor-mancearediscussed.CoagulationPropertyofPolysiloxaneAluminumSulfateandItsEffectonResidualAlinWaterLiMingyuetal(16………)Abstract:Thecoagulationperformanceofpolyaluminiumsilicatesulfate(PASS)andtheamountofresidualaluminumwereresearched.TheeffectsofSiO2/Al,curingtime,stirringtime,andpHoncoagulabilityandresidualaluminumwereinvestigated.ExperimentalresultsshowthatthecoagulationperformanceofPASSisbetterthanaluminumsulfate,andtheresidualaluminumislower.ThefavorablepropertiesofPASSincreasewiththeincreasingofSiO2/Almoleratio.Inaddition,thesourceofresidualaluminumanditsdecreasingmethodswerediscussed.SludgeBulkingandControlinA/OProcessDuYinghao(19……………………………………………………………………)Abstract:TheA/Ophosphorusremovalprocesshasbeenprovedefficientincontrollingthefilamentbulking.ButenoughattentionshouldbepaidtothepotentialriskofthelowDObulkingaswell.Soitisveryimportanttokeepgoodlivingconditionsforthephosphorusremovalbacteria.Someadvicestoinvestigateandcontrolthesludgebulkingarebroughtupinthepaper.NitrousBiologicalNitrogenRemovalTechnologyShiYongsheng(21……………………………………………………………)Abstract:Mechanismsandcharacteristicsofthenitrousbiologicalnitrogenremovaltechnologyandapproachestoachievenitrousbiologicalnitrogenremovalarestudiedinthispaper.Problemsinthecontrolofnitrousnitrificationandprimaryresearchcontentsforthefuturearediscussed.EUGuidelineonResidueandByproductsofDisinfectorsinWaterZhaoWenchao(24…………………………………………)Abstract:Theregulationsonresidueandbyproductsofdisi
