O3/高健磊,刘 玥,高爱华,闫怡新(, 450002) :以耗氧呼吸速率(OUR)为指标,通过正交试验和单因素分析,研究了初始pH值、臭氧流量和反应时间对活性炭催化臭氧氧化预处理克林霉素制药废水可生化性提高的影响。实验结果表明:初始pH值对废水可生化性提高的影响最大,依次为臭氧流量和反应时间;在pH值为10.5,臭氧流量82mg/min,反应时间30min时,废水的可生化性得以极大的提高,OUR值从0升高到0.41mg/(gMLSS·min),为后续生物处理过程创造了良好的条件。:克林霉素;生产废水;O3/活性炭;可生化性;催化臭氧氧化:X787 :A :1003-3467(2008)11-0018-03StudyonPretreatmentofPharmaceuticalWasteWaterofClindamycinbyActivatedCarbonCatalyticOzonationProcessGAOJian-lei,LIUYue,GAOAi-hua,YANYi-xin(CollegeofWaterConservancyandEnvironmentEngineering,ZhengzhouUniversity,Zhengzhou 450002,China)Abstract:Theclindamycinwastewaterispretreatedbyactivatedcarboncatalyticozonationprocessusingoxygenuptakerate(OUR)asindex,throughthesingle-factorexperimentandorthogonalexperimenttostudytheeffectofpHvalue,ozoneflowandreactiontimeonthebiodegradabilityoftheeffluent.Theex-perimentalresultsshowthatpHofthewastewateristhemostimportantinfluencingfactor,followedbyin-letairfluxandreactiontime.UndertheoptimumprocessconditionsofpH10.5,ozoneflow82mg/min,wastewateristreatedfor30minandtheOURvaluecanbeimprovedfrom0to0.41mg/(gMLSS·min),whichisfavorabletothesubsequentbiologicaltreatment.Keywords:clindamycin;wastewater;O3/activatedcarbon;biodegradability;catalyticozonation1 、COD、、、,。,(AOP),,,[1]。O3/,,,,[2]。,,,,,。2 2.1 ,pH10.5,COD30000~40000mg/L,,。COD、、、、、,。 :2008-06-10 :(1963-),,,,,:(0371)63888320。·18·HENANCHEMICALINDUSTRY 2008 25DOI:10.14173/j.cnki.hnhg.2008.11.0132.2 DX09,3mm,;,(30%),(98%),,Na2S2O3,。85-2;HANNA(HI9154);HANNA(HI8424NP)pH;CF-G-3-010g,。2.3 ,1。:、、、。,,,、PVC。(10L,800mm,2.5m)。,2m,50%,5L。:80~800L/h,10~60mg/L。,,,。,,。1 2.4 ①;②;③(),3min,,,,,OUR。2.5 (OUR)。OUR,mgO2/(gMLSS·min)。OUR20℃±1℃,[3-6]。OUR0。3 3.1 O3/OUR,pH、。12。1 pH/min/mg·min-15.010677.0308210.560922 pHminmg/minOURmg/(gMLSS·min)15.010670.0525.030820.0635.060920.147.010820.1857.030920.1367.060670.15710.510920.34810.530670.4910.560820.28k10.070.190.2k20.150.20.17k30.340.180.19R0.270.020.03 2,,pH,。:pH10.5,30min,92mg/min。,。3.2 3.2.1 进水pH值对废水生化性的影响92mg/min,30min,pH。OURpH23。·19·11 :O3/2 pHOUR3 pHpH4.778.59.510.51112pH4.05.35.96.37.49.310.4 2,pH3~10.5,OURpH,pH10.5OUR,00.4mg/(gMLSS·min)。pH10.5OUR。pH10.5。3,,pH,pH11pH,。3.2.2 臭氧流量对废水生化性的影响pH10.5,67、82、92、102、110、112mg/min,30min,OUR,3。3 OUR3,。0~82mg/minOUR,82mg/minOUR00.41mg/(gMLSS·min),82mg/minOUR。82mg/min。3.2.3 反应时间对废水生化性的影响pH10.5,82mg/min,10minOUR,4。4 OUR4,,30minOUR0.41mg/(gMLSS·min)。30min。4 ①,:pH、。,。②pH10.5、82mg/min、30minOUR00.41mg/(gMLSS·min),。:[1] ClausH,GerhardS,OliverS,etal.OxidativedegradationofAOXandCODbydifferentadvancedoxidationproces-ses:Acomparativestudywithtwosamplesofapharma-ceuticalwastewater[J].WaterScienceandTechnology,1997,35(4):257-264.[2] 王凯雄,徐新华,赵伟荣.水与废水的臭氧处理[M].北京:化学工业出版社,2003.36.[3] 马 放,任南琪,杨基先.污染控制微生物学试验[M].哈尔滨:哈尔滨工业大学出版社,2002.106-107,189-190.[4] 刘 颖,张朝辉,张焕胜,等.污水可生化性及其影响因素研究[J].中国海洋大学学报,2005,35(6):1029-1032.[5] 刘 红,闫怡新,王文燕,等.低强超声波改善污泥活性[J].环境科学,2005,26(4):125-126.[6] 于柏秋,徐国平,王东波,等.高浓度有机氰废水处理技术与经济分析[J].辽宁城乡环境科技,2002,22(4):31-34.·20·HENANCHEMICALINDUSTRY 2008 25
