电吸附组合工艺在炼油污水回用中的研究与应用黄 斌1 潘咸峰1 孙晓慰2 邹宗海1 梁 明1(1.,255400;2.,213034):采用生物深度处理-过滤-电吸附除盐组合工艺对炼油二级生化排污进行深度处理,中试和工业应用试验结果表明:该组合工艺具有较好的抗石油类有机物污染的能力,电吸附除盐设备核心部件预期使用寿命长,产水可以直接回用于循环水作补水,浓水达到国家一级排放标准,可以直接排放。该工艺不产生二次污染,属于绿色环保工艺。:电吸附;除盐;炼油污水回用THEAPPLICATIONANDRESEARCHOFELECTROADSORPTIONCOMPOUNDPROCESSINREFINERYWASTEWATERRECLAMATIONHuangBin1 PanXianfeng1 SunXiaowei2 ZouZonghai1 LiangMing1(1.ResearchInstituteofQiluBranchCo.,SINOPEC,Zibo255400,China;2.ESTPurificationEquipmentCo.,Ltd.,Changzhou213034,China)Abstract:Oilrefinerybiochemicaltreatmenteffluenthasbeentreatedbythecompoundprocessofbiologicaladvancedtreatment-filtration-desaltingbyelectroadsorption.Pilot-scaleandindustrial-scaletestresultsshowedthatthecompoundprocesshasabetterabilityofresistingoilpollutant,Thecorepartsofdesaltingequipmentbyelectroadsorptionwillhavelongerusinglife-span,thetreatedwatercanbeusedtothecircularsystemassupplywater,thecondensingwatercanmeetthefirstgradeofGB8978-1996,anditcanbedischargedirectly.Thisprocesswillnotproducethesecondpollution.Keywords:electroadsorption;desalting;reuseofrefinerywastewater0 COD、,、,1600~3000μscm,Cl-、SO2-4,,。,,,,,。()[1-2],、。,。2004,,--,,,。,,,,,。1 [3-4]。11。、,,,(),。、,、,。,,。,,6 200912276DOI:10.13205/j.hjgc.2009.06.0031 。,,。,,,。。,:,、,;1~3mm,,0.15MPa;,,;,,。2 2.1 污水水质与回用技术指标ρ(COD)100mgL,ρ()5mgL,ρ()60mgL,1400~3300μscm,ρ(Cl-)ρ(SO2-4)300mgL。,:ρ(COD)30mgL,800μscm,ρ(Cl-)100mgL,ρ(SO2-4)100mgL。2.2 中试试验流程--,。2。2 2.3 试验结果与分析2.3.1 1。1 mgL%%%ρ(COD)81.946.643.146.30.625.744.542.7ρ()2.660.8866.90.7020.50.4732.70.59ρ(SS)14.29.334.52.474.2 1:COD、,,-。,75%,、、ρ(COD)46.3,25.7,42.7mgL,COD。,,1.55V,。:2H2O2H2+O2,:4OH-2H2O+O2+4e,:2H2O+2eH2+2OH-,1.23V,。,,,。,,COD,COD。2.3.2 ,3。3 3:800μscm。,Cl-62.2%,SO2-475.4%,ρ(Cl-)ρ(SO2-4)100mgL。7 20091227658.6%,58.4%,,,。3 3.1 工业试验流程,,,,(MBBR),。+,。[5],,。4。100m3h,75m3h。MBBR4 3.2 工业试验结果分析3.2.1 ,2。2 MBBR%%%ρ(COD)(mg·L-1)109.267.937.854.020.529.345.751.5ρ()(mg·L-1)2.251.3639.61.0324.30.957.8NTU2.80 2:MBBRCOD、,。,、、ρ(COD)54.0,29.3,51.5mgL,COD45.7%,,COD。3.2.2 ,。,5;,6。5 5:,1461μscm,72h,750μscm,587μscm,59.8%,100.2m3h,77.4m3h,77.3%,0.96kW·h,0.92,。12h,。6 6:,1417~2903μscm,2346μscm,156%。72h,671μscm,71.4%,63.6m3h,43.1m3h,67.8%,1.96kW·h,1.81,。3.3 产水回用情况,(20%~30%),0.020mma,6.29mcm,≤0.100mma、≤20mcm。:。4 ,,,,,。 (11)8 2009122762.3 各生物塘对叶绿素的处理效果6,TP5.0~25mgL,7,4,。,,。6 3 1)、92.0%、89.2%、97.8%;,,。6—10,73,8,。2)、、7,4,、,。7,4,。,。[1] ,.[J].,2005,9(3):271-272.[2] ,.[J].,2003,15(4):377-384.[3] ,,.、[J].,2006,27(3):493-497.[4] JiangSR,LinYF,LeeDY,etal.Nutrientremovalfrompollutedriverwaterbyusingconstructedwetlands[J].BioresourceTechnology,2001,76:131-135.[5] ,,.[J].,2002,23(1):115-117.[6] ,,,.[J].,2006,8(3):47-52.[7] ,,.[J].,2002,21(9):564-567.[8] ,,.[J].,2005,3(2):130-134.[9] ,,,.[J].,2005,25(6):682-686.[10] HansBrix.Domacrophytesplayaroleinconstructedtreatmentwetlands[J].WatSciTech,1997,35(5):11-17. 230061 E-mail zfh168@163.com2008-12-31(8),5000μscm,。5 1)--,,。2),,,。,,,。[1] ,.[J].,2003,29(2):63-66.[2] ,,,.[J].,2005,25(4):72-74.[3] ,.(EST)[J].,2002,33(4):18-20.[4] .[G]2002.:,2002:52.[5] ,,,.[J].,2008,2(5):64. 255400 46E-mail huangb@riqpc.com2008-12-0111 200912276
