富马酸废水厌氧处理试验研究张一波

张一波,邹华　(,214122)　[目的]探索厌氧生物法处理富马酸废水的可行性。[方法]先分阶段将原废水稀释至一定浓度,调节原水pH值,通过蠕动泵送入厌氧反应器进行生物处理,出水再循环至反应器,测定不同反应时间出水的化学需氧量和pH。[结果]在污泥驯化阶段,进水的化学需氧量浓度约为1564mg/L,经过约48h的连续运行,化学需氧量的去除率可达到约81%;在提高负荷和稳定运行阶段,进水的化学需氧量浓度约为10377mg/L,经过约32h的连续运行,化学需氧量的去除率可达到约60%,可见应用厌氧反应器对处理富马酸此类高浓度有机废水具有良好的作用。[结论]该研究为企业废水处理提供了科学依据。　富马酸废水;厌氧处理;化学需氧量　X703　　　A　　　0517-6611(2009)04-01726-02StudyonAnaerobicTreatmentExperimentofFumarateWastewaterZHANGYi-boetal　(SchoolofEnvironmentandCivilEngineering,JiangnanUniversity,Wuxi,Jiangsu214122)Abstract　[Objective]Theaimwastoexplorethefeasibilityoffumaratewastewatertreatmentbyanaerobicbiologicaltreatment.[Method]Theoriginalwastewaterwasdilutedtoacertainconcn.bystagesanditspHvalueadjusted,thenitwassenttotheanaerobicreactorbyperi-stalticpumptobiologicallytreat,thentheeffluentwasrecycledandreachedthereactor,thechemicaloxygendemand(COD)andpHoftheeffluentinthedifferentreactiontimesweredetected.[Result]Duringthesludgeacclimationstage,theconcn.oftheinfluentCODwas1564mg/Landaftercontinuousoperationfor48h,theremovalrateoftheCODcouldreachabout81%;atthestagesofincreasingloadandstableoperation,theconcn.oftheinfluentCODwas10377mg/Laftercontinuousoperationfor32h,theremovalrateoftheCODcouldreachabout60%,whichshowedtheanaerobicreactorhadgoodeffectonthetreatmentforthiskindofhighconcn.oforganicwastewatersuchasfumarate.[Conclusion]Theresearchprovidedthebasisfortheindustrialwastewatertreatment.Keywords　Fumaratewastewater;Anaerobictreatment;Chemicaloxygendemand　张一波(1974-),男,江苏无锡人,在读硕士,工程师,从事环境监测、水污染控制技术方面的研究工作。　2008-11-12　　、,。。、,[1]。,:[2];[3],、。。,EGSB、IC,。,。,,。1　1.1　　,,50t/d,COD63000mg/L,pH≤1.85。1。1　Table1　CharacteristicsofthemainpollutantsinwastewaterPollutantsnameg/LSolubilityCODg/gBOD5g/gB/CMaleicacid788.0　0.830.570.687Fumaricacid7.0　0.770.600.779Sulfo-urea92.0　---O-xylene0.1　3.170.980.309PhthalicAnhydride　Sparinglysoluble1.621.200.7411.2　　:FeSO4、K2Cr2O7、Ag2SO4,(NH4)2Fe(SO4)2、H2SO4,()。(IC),,,1.0～1.5mm。:9070MBE();AF1104();Delta320(-)。HL-2()。[4]:COD;pH。1.3　　,pH,,。,1,1.2L。1　Fig.1　Schematicchartoftester2:,,　罗芸　　屈满义,JournalofAnhuiAgri.Sci.2009,37(4):1726-1727、,COD。、。2　,,pH,COD1500mg/L,CODpH。(2),,COD1564mg/L,48h,COD81%,,。2　CODpHTable2　TheCODandpHvalueofthewaterdischargeinthedifferentreactiontimeofthefirstphase∥hTimeCOD∥mg/LWaterinletWateroutlet∥%RemovingratepHpHvalue0　1564.07--2.594949.3739.317.288924.5240.897.6312874.0044.117.3620717.1554.157.4824662.5157.647.4328683.0056.337.5940660.8057.757.3244324.4279.267.9148286.8681.667.82　　,,pH,COD10000mg/L,CODpH。(3),,,、。　　,COD10377mg/L,32h,COD60%,。3　CODpHTable3　TheCODandpHvalueofthewaterdischargeinthedifferentreactiontimeofthesecondphase∥hTimeCOD∥mg/LWaterinletWateroutlet∥%RemovingratepHpHvalue010377.38--2.5946367.9438.647.4786407.2538.267.62165385.2348.117.97205110.0750.767.21244245.2959.108.16324166.6759.857.923　,,,[5]。,。,,,[6]。,,COD10000mg/L,32h,COD60%。[1]陈华,严莲荷,陈媛,等.富马酸废水降解菌的选育及降解效果[J].环境科学与技术,2005,28(6):75-76.[2]蒋齐光,严莲荷,周申范.微波催化氧化法处理富马酸废水[J].化工环保.2005,25(3):217-219.[3]彭绍玲,伍钦.生物接触氧化法处理富马酸废水[J].华南理工大学学报:自然科学版,2004,32(5):71-73.[4]国家环境保护总局水和废水监测分析方法编委会.水和废水监测分析方法[M].4版.北京:中国环境科学出版社,2002.[5]胡纪萃.废水厌氧生物处理理论与技术[M].北京:中国建筑工业出版社,2003.[6]刘志,刘丽,于涌.厌氧水解改善富马酸废水的可生化性研究[J].环境科学与技术,2003,26(1):14-15.(上接第1725页)　　(3)NH3-N、NO-3-NNO-2-NUV254。[1]EATONAD.MeasuringUV-Absorbingorganics:Astandardmethod[J].JourAWWA,1995,87(2):86-90.[2]小仓纪雄.天然水的紫外吸光度与水质因子间的关系[J].日本化学杂志,1986(12):1286-1289.[3]EDZWALDJK.Coagulationindrinkingwatertreatment:Particles,　or-ganicsandcoagulants[C]//Controloforganicmaterialbycoagulationandfloc-Separationprocess,waterScienceTechnology.Oxford:PergamonPress,1993:21-35.[4]DENNETTKE,AMIRTHARAJAHA,MORANTF,etal.Coagulation:Itseffectonorganicmatter[J].JourAWWA,1996,88(4):129-142.[5]蒋绍阶,刘宗源.UV254作为水处理中有机物控制指标的意义[J].重庆建筑大学学报,2002,24(2):61-65.·1727·37卷4期　　　　　　　　　　　　　　　　张一波等　富马酸废水厌氧处理试验研究
