INDUSTRIALWATER&WASTEWATER 工业用水与废水 ..2012 UV/Fenton处理苯酚废水王来斐(上海勘测设计研究院,上海 200434) 的研究摘要:采用UV/Fenton联合体系降解苯酚模拟废水,苯酚的初始质量浓度为300mg/L,COD的初始质量浓度为760mg/L。探讨了pH值、H02(30%)和FeSO4·7H20投加量、反应时间等因素对苯酚和CODcr去除率的影响。结果表明,UV/Fenton联合体系降解苯酚废水的最佳工艺条件是:溶液pH值为3、、 FeSO4·、反应时间为90min。此时,苯酚的去除率为95%,COD。的去除率为90%。UV/ Fenton联合体系能较好地处理苯酚废水关键词:Fenton试剂;苯酚;紫外光;废水处理中图分类号: 文献标识码:A 文章编号:1009—2455(2012)05—0020—03 TreatmentofphenOl—cOntainingwastewaterbyUV-Fentonprocess WANGLai-fei (ShanghaiInvestigation,DesignandResearchInstitute,Shanghai200434,China) Abstract:UV—Fentonprocesswasusedtotreatsimulantphenol—containingwastewater,theinitialmass concentrationsofphenolandCODc~were300and760mg/,dosageof H2O2(30%)andFeSO4·7H2O,reactiontimeandsomeotherfactorsontheremovalratesofphenolandCODCrwere ,theoptimalconditionforUV-Fentonprocesstreatingphenol-containing wastewaterwasasfollows:thesolutionpHvaluewas3,thedosageofH202andFeSO4· ,,theremovalratesofphenoland CODcrreached95%and90%,UV—Fentonprocesswaseffectiveforthe treatmentofphenol—containingwastewater.
