原水水质在管道输送中的变化规律

原水水质在管道输送中的变化规律曲志军,尤作亮,徐洪福(深圳市水务集团有限公司水技术研究所,广东深圳518035):对比研究了预加氯和未预加氯两种条件下原水水质在输送管道中的变化规律结果表明,原水预氯化可以抑制藻类在管道中的生长繁殖,并提高原水的溶解氧浓度原水预氯化会生成多种有害副产物,增加水的致突变活性,形成大量对人体有害的卤代有机物,因此氯的投量不宜过大:原水输送;水质变化;预氯化:TU991:A:1673-9353(2007)02-0005-05VariationofRawWaterQualityinDistributionPipesQUZhijun,YOUZuoliang,XUHongfu(InstituteofWaterTechnology,ShenzhenWaterGroupCo.Ltd.,Shenzhen518035,China)Abstract:Variationsofrawwaterqualityindistributionpipeswerecomparedwithandwithoutpre-chlorination.Theresultshowsthatprechlorinationcaneffectivelycontrolalgaeandincreasedissolvedoxygen.Prechlorinationresultsinmanykindsofharmfulby-products,additionofmutagenandformationofhalogenorganicswhichisharmfultohumanbeings.Keywords:rawwater;variationofwaterquality;prechlorination,,,90%,:,C,1原水输送现状及分析,ABC,1,,,,,,ABC4,,,11Fig.1Diagramofrawwaterdistributionsystem1Tab.1RelativeparametersinthedistributionofrawwateryAAyBByC/(m#s-1)1.7601.3861.073/h1.1501.1602.175#5#1220076WATERTECHNOLOGYVo.l1No.2Jun.20072结果与讨论211,:¹22Fig.2VariationsofchromaticityandturbidityC,2518.5(26%),4.28NTU3.22NTU(24.8%),,º343Fig.3Variationsofammoniumnitrogenandnitritenitrogeninnetwork4Fig.4VariationofnitratenitrogeninnetworkC,,1.61mg/L0.60mg/L,0.402mg/L0.246mg/L,,,C,62.7%,,,4.05mg/L,C4.30mg/L,0.25mg/L(5.8%),,,pH,pH6.86,C6.64C,35.2mg/L31.8mg/L,55pHFig.5VariationsofpHvalueandtotalalkalinityinnetwork»,BOD5BOD5CODCr(6),,BOD5CODCr6CODCrBOD5Fig.6VariationsofCODCrandBOD5innetwork#6#1220076¼A,,7.74mg/L5.65mg/L;AC,,,,,,77Fig.7Variationofdissolvedoxygeninnetwork8Fig.8VariationofalgaeinnetworkC,,,,,¾AOCTOCAOCTOC22AOCTOCUV254Tab.2VariationsofAOC,TOCandUV254innetworkABCAOC()/(Lg#L-1)177175250163UV254/(cm-1)0.04280.04210.04060.0375TOC/(mg#L-1)1.981.972.031.81,B,AOCTOCA,B,AC3,AOCTOC,99AOCTOCFig.9VariationsofAOCandTOCinnetwork¿UV254UV254,,1010UV254Fig.10VariationofUV254innetwork,;212C,,,,,1.0~2.5mg/L¹,,,#7#20076,:1241.1%,44.3%55.4%,,AC,,,ABC,23.1%30.8%,,BA(14.1%),CA,1111Fig.11Algaeconcentrationsofrawwaterwithandwithoutprechlorinationinwaterworksº12~14,,,3,BC,12Fig.12Nitritenitrogenconcentrationsofrawwaterwithandwithoutprechlorinationinwaterworks13Fig.13Nitratenitrogenconcentrationsofrawwaterwithandwithoutprechlorinationinwaterworks14Fig.14Ammoniumnitrogenconcentrationsofrawwaterwithandwithoutprechlorinationinwaterworks,3,,;,,,,,»,,,CODCr,15¼,,#8#1220076,,,1615CODCrFig.15CODCrofrawwaterwithandwithoutprechlorinationinwaterworks16Fig.16Dissolvedoxygenconcentrationsofrawwaterwithandwithoutprechlorinationinwaterworks3结语,,,;;,,,,,:[1],,,.[J].,2004,26(5):64-67.[2],,,.[A].[C].:,2004.[3],,.[J].,2004,26(3):1-4.[4],.[J].,2002,18(6):14-17.E-mail:[e-mail]:2007-04-29(上接第4页),,,,,-,,,1.5~3mg/L1mg/L0.020/m3(,1.0/kg,15kW#h,10%,0.67/(kW#h)),20/(kgO3#h),,()15min(2m,8m/h),0.041/m3(6000/,t2),,:¹,,;º,,;»+,,E-mail:[e-mail]:2007-05-30#9#20076,:12
