城镇生活污水中氨氮的去除研究杨志水

　　　201028城镇生活污水中氨氮的去除研究杨志水1　姜　斌2(1.,　325400;2.,310007)　:借助曝气生物流化池污水处理工艺对于城市生活污水中氨氮的去除研究实验,详细阐述了城市生活污水中氨氮的去除机理及其过程的实施,即实现硝化、反硝化过程的工艺条件。同时,在该实验过程中把常规的活性污泥法和曝气生物流化池两种污水处理工艺,对城镇生活污水中氨氮的去除效果做了对比实验,实验结果表明:要使城市生活污水中的氨氮得到去除,最好运用集硝化-反硝化于一体的生化处理装置,因为这样不但能真正实现脱氮目的、而且工艺过程简单,并可以节省空气利用量,其对大量低碳高氮废水的处理具有重要意义。:硝化菌;反硝化菌;污泥龄;碱度RESEARCHONREMOVALOFARNMONIA-NITROGENINMUNICIPALDOMESTICSEWAGEYangZhishui1　JiangBin2(l.ZhejiangPingyangEnvironmentalProtectionAgency,Pingyang　325400,China;2.HangzhoushenzhanEnvironmentalProtectionandEngineeringLimitedCompany,Hangzhou　310007,China)Abstract:Thepaperdescribedammonia-nitrogen'sremovalmechanismandimplementationprocess,accordingtotheremovalofammonianitrogeninmunicipalsewagebyaeratedbiofluidizedtank.Itwasalsocomparedtheremovaleffectofammonianitrogeninmunicipalsewagebetweentraditionalactivatedsludgemethodandaera-tionbiologicalfluidizedtank.Theresultsshowedthatthebestmethodtoremoveammonianitrogeninmunici-palsewageistheuseofasystemwithnitrificationanddenitrification.Becausethiscouldachievedenitrificationprocessandsavetheairamount.Soaerationbiologicalfluidizedtankhasimportantmeaningforthetreatmentoflow-carbonandhigh-nitrogenwastewater.Keywords:nitrifyingbacteria;denitrifyingbacteria;sludgeage;alkalinity0　,GB18918-2002《》,、,,。:1),;2),;3)C/N,,。,,。1　1.1　生活污水中氮的存在形式、,(),,0.6～0.8。1.2　脱氮过程:、、。1.2.1　,,,2%～3%,,。147DOI:10.13205/j.hjgc.2010.s1.043　　　2010281.2.2　,,,。。:1gNH4-N,7.14g(CaCO3),4.57g,,,,:1):,,CO32-HCO3-(),200mg/L,,。,CO32-、CO2、HCO3-,,-,,(),,BOD5。BOD5(60mg/L),,。,,COD、(CO32-、HCO3-)、2。,,。30g/L,,。,,。2):,25～35℃,,,,(,),,,,。,,,、,,,。1.2.3　NO2-、NO3-,,。,,,,,。-,,,、、,。2　,、,,-,,,,,,0.8m3,60%。2.1　实验1:(1)。1　mg/LNH3-NCODBOD5SST-NT-P37.8320.2150.5220.855.64.782.1.1　1。200L/h。2.1.2　,,2、3。148　　　2010281　2　3　COD　　2、3,,,,COD,,,,,1CODBOD5,,2、3、4。2.2　实验21):。250L/h。2):1。2　mg/LNH3-NCODBOD5SST-P32.558.215.655.72.5　　3):,,,4。4　2.3　实验总结1,,,COD、,COD,,5%,,,COD。2、3、4,,,,、,,、,,,2、3、4,,,,,,,,。,。,,,(156)149　　　201028CSOs,,CSOs,。,、、,,。[1]BendickJA,ModiseCM.Applicationofcross-flowmicrofiltratioaforthetreatmentofcombinedseweroverflowwastewater[J].Jour-nalofEnvironmentalEngineering,2004,130(12):1442-1449.[2]Gromaire-MertzMC,Gamaud.CharacterisationofUrbanRunoffPollu-tioninParis[J].WaterScienceandTechnology,1999,39(2):1-8.[3]ChebboG,GromaireMC.Productionandtransportofurbanwetweatherpollutionincombinedsewersystems:the“Marais”experi-mentalurbancatchmentinParis[J].UrbanWater,2001(3):3-15.[4]SchulzW,BrechenmacherM.CombinedSewerOverflowfromtheCityAreaofMunich[J].ScienceoftheTotalEnvironment,1994,147:493-498.[5]GromaireMC,GarnaudS,AhyerreM,etal.TheQualityofStreetCleaningWaters:ComparisonWithDryandWetWeatherFlowsinAParisianCombinedSewerSystem[J].UrbanWater,2000(2):39-46.[6]FDiaz-FierrosT,PuertaJ,SuarezJ,etal.ContaminantloadsofCSOsatthewastewatertreatmentplantofacityinNWSpain[J].UrbanWater,2002(4):291-299.[7]KimSW,ParkJB.Possibilityofsewageandcombinedsewerover-flowreusewithbiologicalaeratedfilters[J].WaterScienceandTechnology,2007,55(1-2):1-8.[8],,.[J].,2007,29(7):541-543.[9]、、,.[J].,2005,31(7):9-11.[10].[J].,2007,31(4):84-86.[11],,,.-[J].,2006,32(9):23-35.[12],,,.[J].,2006,22(19):25-28.[13],.[J].,2007(2):23-24,26.[14]、、,.[J].(),2007,39(6):834-838.[15],,,.[J].,2004,23(3):18-23.[16],,.[J].,2003,9(10):38-42.[17]UhlM,DittmerU.ConstructedwetlandsforCSOtreatment:anoveriewofpracticeandresearchinGermany[J].WaterScienceandTechnology,2005,51(9):23-30.[18]DavidLM,MatosJS.Combinedseweroverflowemissionstobath-ingwaterinPorugal.Howtoreduceindenselyurbanisedareas?[J].WaterScienceandTechnology,2005,52(9):183-190.[19],,,.[J].,2005,21(8):19-22.[20]AndohRYG,SaulAJ.Theuseofhydrodynamicvortexsepara-torsandscreeningsystemstoimprovewaterquality[J].WaterSci-enceandTechnology,2003,47(4):175-183.[21]YoonTI,KimCG.Casestudiesonrapidcoagulationprocessestocopewithtotalemissioncontrols[J].Desalination,2008,231(1-3):290-296.[22],,.[J].,2005,21(11):6-9.[23]JimenezB,ChavezA,LeyvaA.Sandandsyntheticmediumfiltra-tionofadvancedprimarytreatmenteffluentfromMexicoCity[J].WaterResearch,2000,34(2):473-480.　　200092　5283504E-mail　[e-mail]2010-05-12(149),,,,,COD,-,,,,。,,3,3、4,(5mg/L)。、、2、44。3　,,,,,、,,。,、,,、。　　325400　　E-mail　[e-mail]2010-03-12156
