第1期臭氧/过氧化氢处理高浓有机废水的研究徐卫东,谈娟娟,赵振华,高峰(江苏蓝必盛化工环保股份有限公司,江苏宜兴214200)摘要:以某农药厂的高浓含醚有机废水为研究对象,采用臭氧(O3)/过氧化氢(H2O2)联用高级氧化工艺对其进行处理,利用单因素分析方法探讨废水初始pH、臭氧浓度、过氧化氢投加浓度对氧化效果的影响。优化条件为:直接处理pH为14的原废水,臭氧浓度最高可为159mg/L(臭氧输出为70%),30%过氧化氢总投加浓度为6.0mL/L;优化条件下氧化降解3h后,TOC从4834mg/L降至780mg/L,TOC去除率达84%,O3/H2O2工艺对难生物降解含醚有机废水具有良好的降解效果。但进一步增大臭氧浓度或过氧化氢投加浓度并不能显著提高废水的TOC去除率,反而降低两者的有效利用率。关键词:臭氧;过氧化氢;含醚有机废水;TOC中图分类号:X703.1文献标志码:A文章编号:1009-9212(2023)01-0083-05DOI:10.19342/j.cnki.issn.1009-9212.2023.01.017TreatmentofHighConcentrationOrganicWastewaterbyanO3/H2O2ProcessXUWei-dong,TANJuan-juan,ZHAOZhen-hua,GAOFeng(JiangsuLasonChemicalEnvironmentalProtectionCo.,Ltd.,Yixing214200,China)Abstract:Ahighconcentrationether-containingorganicwastewaterfromapesticideplantwastreatedbyO3/H2O2oxidationprocess,andtheeffectofinitialpH,concentrationofO3andH2O2onoxidationwasstudiedbythemethodofsinglefactoranalysis.Theresultsshowedthat:thiswastewatercouldbetreateddirectlyfromtherawwateratapHof14,andtheTOCofwastewatercouldbereducedfrom4834mg/Lto780mg/Lwitharemovalrateof84%after3hoursofthedegradationunderthefollowingprocessconditions:thehighestO3concentrationwas159mg/L(O3outputpercentagewas70%);andthetotalconcentrationof30%H2O2was6.0ml/L.Thus,itcanbeseenthattheO3/H2O2processhadasignificanteffectonthedegradationoftheether-containingorganicwastewater.TheremovalrateofTOCcouldnotobviouslybeimprovediffurtherincreasingtheconcentrationofO3orH2O2,whiletheeffectiveutilizationrateofbothwasreduced.Keywords:ozone(O3);hydrogenperoxide;ether-containingorganicwastewater;totalorganiccarbon(TOC)作者简介:徐卫东(1970—),男,江苏宜兴人,环保工程师,研究方向:化工废水治理的研究(E-mail:jjtan1983@163.com)。收稿日期:2022-11-25安全...
