201028O3-GAC工艺对高含盐采油废水深度处理试验研究*张晓辉1,2 吴 飞3 崔建宇1 曹奇光2 胡林1(1., 100094;2., 100029;3., 100088) :采用臭氧和颗粒活性炭(GAC)对经过二级处理后的高含盐采油废水进行深度处理。研究结果表明:对过滤后废水采用O3单独氧化处理,COD和TOC去除率分别为77%和49%;采用GAC动态吸附,当停留时间达30min时,COD和TOC浓度均低于排放标准;采用臭氧-活性炭结合的方式,COD和TOC去除率分别达80%和74%,其出水指标均达《辽宁省污水综合排放地方标准》(DB21/1627-2008)一级排放标准的要求。:采油废水;深度处理;颗粒活性炭;臭氧EXPERIMENTALRESEARCHONADVANCEDTREATMENTOFHIGH-SALTPETROLEUMWASTEWATERBYO3-GACPROCESSZhangXiaohui1,2 WuFei3 CuiJianyu1 CaoQiguang2 HuLin1(1.CollegeofResourceandEnvironmentalSciences,ChinaAgriculturalUniversity,Beijing 100094,China;2.DepartmentofBiotechnology,BeijingVocationalCollegeofElectronicScience,Beijing 100029,China;3.CSD(Beijing)EP.DevelopmentCo.Ltd,Beijing 100088,China)Abstract:Advancedtreatmentofpetroleumwastewateraftersecondarytreatmenthasbeenresearchedbyozo-nationandgranularactivatedcarbon(GAC)process.TheresultindicatesthattheremovalratesofCODandTOCare77%and49%respectively,whentheozonationprocesshasbeenusedfollowedbyfiltrationprocess.TheCODandTOCoftheeffluentarebothbelowthedischargestandardofwastewater,whenGACdynamicadsorptionhasbeenusedandretentiontimeis30min.TheremovalratesofCODandTOCare80%and74%respectively,whentheozonation-GACcombinationprocesshasbeenused.TheCOD&TOCoftheef-fluentcanmeetthedischargestandardspecifiedin“IntegratedWastewaterDischargeStandardofLiaoningProvince”(DB21/1627-2008).Keywords:Petroleumwastewater;advancedtreatment;GAC;ozonation*(YZK2009006);。1 “”,、、,65~75℃,10000~12000mg/L,6923~9000mg/L。,“---MBBR-CAST-”,1。6000~7000m3/d,GB18486-2001《》1。200871,DB21/1627-2008《》,200971。1。,GB18486-2001,DB21/1627-2008,TN、COD,TOC。,:1),,COD,;2)/TN,,,4DOI:10.13205/j.hjgc.2010.s1.011 201028,;3),COD。4)TOC,TOC。1 1 mg/L(pH)pHρ(CODCr)ρ()ρ(TP)ρ(NH3-N)ρ(TN)ρ(TOC)8.5-9.2118-13580.520(5)GB18486-20016-9300128.02540120DB21/1627-20086-9503.00.58(10)1520 :(1)12℃,≤12℃。(2)TNTOC,。2 2.1 试验装置2.1.1 O31L,2h。,,500mLGAC,CODTOC。2.1.2 GAC:500mL2.1.1,5gGAC,25°C、200r/min2h,,CODTOC。:GAC,GAC240g,GAC,10,20,3060min,,CODTOC。2.2 试验方法,。COD:,《》()。TOC:-,TOC680°C。TOC,TOC-5000。:1L,,70μm,Millipore。3 3.1 水样中SS对COD的贡献COD2。,,,COD28%,COD,。2 COD3.2 O3对COD、TOC的去除效果2h。,,。CODTOC3。,。,[1-3]。 COD,TOC,CODTOC,CODTOC77%49%,,5 2010283 CODTOC,,,[4],CODTOC,CODTOC,。3.3 GAC对COD、TOC的去除效果3.3.1 ,2h,,CODTOC4。,CODTOC14%26%,COD,TOC。,COD[5],,。4 GACCODTOC3.3.2 ,,CODTOC,5。 5,CODTOC,30min,,5 GACCODTOC。、、COD。3.4 O3-GAC组合对COD、TOC的去除效果,CODTOC,6。,-CODTOC80%74%,,,CODTOC。-。6 O3-GACCODTOC4 :1)SSCOD,,COD;2),,、、;(21)6 2010282,。4,,。4 2007mg/L(pH)ρ(COD)ρ(BOD5)ρ()ρ(SS)ρ()pHρ(NH3-N)577~1592147~4394.2~8.244~911.3~5.46.9~8.415.4~51.69432685.269.82.97.630.512.5~59.51.8~9.82.0~3.630.6~43.90~0.26.0~6.60.2~5.137.44.72.837.50.056.31.9100205701.06~915 ,7,,,,,。2002,,、、、,,,100%,,。4 1),,,,。2),。3)SBR,,,。SBR,H+、NO-2NO-3,(C4H8SO2)、H+SO2-4,pH。ρ(COD)1800mg/L,pH6.0,。[1],[J].,1991,20(3):50-56.[2],[J].,1989,18(1):20-22.[3].[J].,1988,17(1):46-51.[4],.—[J].,2001,21(3):45-46.[5],.—[J].,1999,17(2):19-22.[6].()—[J].,1998,18(4):337-340. 610041 E-mail lixd@cib.ac.cn2009-07-07(6) 3)-DB21/1627-2008,CODTOC,,。[1],.[J].,2008,24(1):105-108.[2]./[J].,2004,33(5):273-275.[3]VanderKooij,eta1.Theeffectofozonatio,biologicalfiltrationanddistributionontheconcentrationofeasilyassimilableorganiccarbonindrinkingwater[J].OzoneSciEngi.,1989,11:297-311.[4],,.-[J].,2007,33(11):53-56.[5],,.UV/O3-GACO3-GAC[J].,34(1):22-25. 100094 E-mail hulin@cau.edu.cn:(010)627337292009-06-1821
