摘　　要：研究了用ＵＶ-ｖｉｓ／Ｈ２Ｏ２／草酸铁络合物法处理含酚废水时诸因素对ＣＯＤ去除效果的影响。通过正交试验确定最佳工艺条件：初始ｐＨ＝３．７，Ｈ２Ｏ２、ＦｅＳＯ４、Ｋ２Ｃ２Ｏ４加入量为３５ｍｍｏ１／１、２０ｍｍｏ１／１、５０ｍｍｏ１／１，反应的持续时间 ６０ｍｉｎ，此条件下再经絮凝处理，废水ＣＯＤ由６５０ｍｇ／１降至３２ｍｇ／１左右，去除率达９５％；挥发酚由１５ｍｇ／１降至０．５ｍｇ／１以下，去除率近９７％。本法的处理效果和能耗均好于 ＵＶ／Ｆｅｎｔｏｎ法。The effect of some factors on the COD removals in wastewater containing phenol were inves- tigated by UV-vis/H2O2/Ferrioxalate complexes process. The optimal conditions were determined by orthogonal experiments. When the adding amount of H2O2, FeSO4, K2C2O4 were 35mol/L, 20mol/L 50mml/L respectively, pH = 3.7 and the reacting time was 60min, the COD value dropped from 650mg/L to about 32mg/L and the volatile phenols content changed from l5mg/L to less than 0.5mg/L. The COD remova1s are up to 95%. The phenols degrading rate is 97%. This process has a much higher effciency and lower energy consumption than do the UV/Fenton process.
