纺织印染厂废水的深度处理中试及工程应用汪晓军 顾晓扬 简 磊(,510006):采用曝气生物滤池(BAF)-臭氧-曝气生物滤池工艺对广东某大型纺织印染厂的常规水解酸化-接触生物氧化处理出水进行深度处理回用中试,在中试研究成功的基础上,设计了每小时处理5t的工业化试验装置。试验运行结果表明:进水COD为100～150mgL,色度约80倍,浊度约10NTU,在前BAF水力停留时间3h,中间化学氧化池中臭氧投加量40mgL,后BAF水力停留时间2h的情况下,经组合工艺处理后出水COD约30mgL,色度2倍,浊度1NTU,该工艺处理后的出水,可直接回用于对电解质浓度要求不高的生产工艺中,也可作为反渗透或纳滤膜的预处理工序。:纺织废水;臭氧;曝气生物滤池;深度处理PILOTPLANTSTUDYONADVANCEDTREATMENTOFTEXTILEWASTEWATERWangXiaojun GuXiaoyang JianLei(SchoolofEnvironmentalScience&Engineering,SouthChinaUniversityofTechnology,Guangzhou510006,China)Abstract:Thebiologicalaeratedfilter(BAF)-ozonizing-BAFprocesswasusedasadvancedtreatmenttotreatthetextiledyingwastewaterafterconventionalbiologicaltreatment.Basedonthepilotplanttestresults,theindustryscaletreatmentsystemwassetup.ThetreatmentresultsshowedthattheinfluentCODwas100～150mgL,colorwasabout80times,turbiditywasabout10NTU,theretentiontimeofpre-BAFwas3hours,thedosageofozonewas40mgL,andtheretentiontimeofpost-BAFwas2hours,usingthecombinationprocesstheeffluentqualitieswerethatCODwaslessthan30mgL,turbiditylessthan1NTUandacolorityof2times.Keywords:textilewastewater;ozone;biologicalaeratedfilter;advancedtreatment0 。、、、、,。、,,、、,。,,,,。:、、、[1-6]。(0.05～1.5nm);,,,,,;,;,。,-。,、、、、(BAF),,。,,COD,,。,,。1 3 200912276DOI:10.13205/j.hjgc.2009.06.002,1。1 pH6～96～810～402～4NTU6～101ρ(COD)(mg·L-1)110～150402 20Lh,-,3h,,2。:,COD15.7%,8,3.7NTU,。,COD、、,30mgL,,,。2 -COD(mg·L-1)ρ(COD)(mg·L-1)NTUBAFBAFBAF074.574.562.81616167.07.03.71576.864.642.416846.94.41.83080.565.929.216428.13.40.94578.663.120.616227.72.40.86088.264.515.816228.92.50.87575.260.212.616227.32.10.73 3.1 试验验证装置5th,--,1。1 BAF--BAF,,。,1.9m,4.5m,2.5h。3∶1,3～5mm。,2,,ρ(COD)1000mgL,3d,。1th12,,,5th。,,2,。3.2 试验结果与讨论3.2.1 ,-,,SO2-4,,,,。,,。,,,,。,,,。BAF3,,,BAF,40%。3 h5.305.316.16.26.36.46,56.6ρ(COD)(mg·L-1)132118134130118112120110121.8ρ(COD)(mg·L-1)716777616462686867.2%46.243.242.553.145.844.643.338.244.83.2.2 -,,-,。,pH。,200gh,,4 200912276,,。-4,,,COD49.3mgL,,。,BAF,。4 - h5.305.316.16.26.36.46,56.6ρ(COD)(mg·L-1)716777616462686867.2515359404350485049.3252831313228212527.6COD%64.858.259.749.250.054.869.163.258.9856585807060706075222221212NTU2.12.52.92.82.62.42.52.32.60.50.50.80.80.50.50.50.80.63.3 经济技术分析BAF--BAF,:13h,5∶1;30～45mgL,22h,2∶1。COD30mgL,2,1NTU。1kg30kW,0.9～1.5kW,0.7,0.6～1.0t,0.3～0.5t,1.2～2.0,,2.5t,,。4 1),,COD44.8%。COD,0.1～0.2。2)。30mgL,,,40mgL,COD20mgL,COD26%。COD,,4,,。3)2COD,COD44%,COD30mgL,2,1。4),,,。,COD、SS,,。,COD30mgL,3,,COD90mgL,。[1] ,,,.[M].:,2002:290.[2] ,.[J].,2002,18(3):30-32.[3] ,.[J].,1995,10(2):8-10.[4] BruceER,DouglasSS,etal.Treatmentofacoloredgroundwaterbyozone-biofiltration:pilotstudiesandmodelinginterpretation[J].WatRes,2002,36:3387-339.[5] ,,.[J].,2002,18(8):26-29.[6] WangXiaojun,GuXiaoyang,LiDexian,etal.Treatmentofacidrosedyecontainingwastewaterbyozonizing-biologicalaeratedfilter[J].DyesandPigments,2007,74:736-740. 510006 (020)39380528E-mail cexjwang@scut.edu.cn; 200912276
