摘　　要：研究了UV/Fenton法处理含苯酚废水时H2 O2 和FeSO4 加入量及苯酚初始浓度对酚去除效果的影响及C2 O2 -4 对UV/Fenton法的增强效果。 [H2 O2 ]=2 0mmol/L ,[FeSO4 ]=5mmol/L ,反应 2 0min ,苯酚初始浓度为 5 0mg/L时 ,酚去除率达 99%。UV/Fenton体系中引入C2 O2 -4 后可有效提高对紫外和可见光的利用率 。The UV/Fenton process is an advanced oxidation process, by which phenols in wastewater can be degraded. Here we investigated the effect of the adding amount of FeSO 4 ?H 2O 2 and the initial concentration of phenols in wastewater on the removal efficiency of phenols. When the concentration of H 2O 2 and FeSO 4 added are 20 and 5mmol/L in water sample, respectively, the phenols removing efficiency is up to 99% after reacting for 20min with the initial concentration, 50mmol/L. The utilizing rate of ultraviolet and visible light would be promoted by adding C 2O 2- 4 ions into UV/Fenton system, therefore the phenols removal efficiency can be increased.
