摘　　要：利用Fenton氧化处理某废油提炼厂的高含油工业废水。通过正交试验设计确定Fenton氧化最佳实验条件为pH=3,H2O2投加量为60 mL/L,n(H2O2)/n(Fe2+)=15,反应时间为90 min.在此条件下,Fenton氧化对废水中有机物的去除率可达49.2%。基于实验数据建立有机物降解的动力学模型,得到制约Fenton氧化反应速率的主要因素是H2O2投加量,反应的初始活化能为9.15 kJ/mol.The high oil-containing industrial wastewater from a waste oil refinery was treated by Fenton oxidation.The optimum experimental conditions for Fenton oxidation determined by orthogonal test were as follows:pH=3,H2O2 dosage of 60 mL/L,n(H2O2)/n(Fe2+)=15,reaction time of 90 min.Under the condition,the removal rate of organic matter from wastewater by Fenton oxidation reached 49.2%.The results of the kinetic model of organic matter degradation based on experimental data revealed that the main factor restricting the reaction rate of Fenton oxidation was the H2O2 dosage,and the initial activation energy was 9.15 kJ/mol.
