摘　　要：采用UV/Fenton技术处理金属切削液废水,并通过正交实验和单因素实验得到了最佳工作条件为:pH=2.5,H2O2(浓度30%)投加量=127.5 mL/L,Fe2+投加量=24.8 mmol/L,总反应时间=3 h,投加次数6次,此条件下金属切削液废水COD去除率达到95%。最后,通过正交实验数据和单因素模型方程利用1st Opt进行多元非线性拟合建立UV/Fen-ton对金属切削液废水COD降解率的数学模型方程,然后进行分析讨论。Abstract The metalworking fluids wastewater was treated by UV/Fenton. The optimum conditions deter- mined by the orthogonal experiment and single-factor experiment were as follows ： pH = 2.5, Fe2 ＋ adding capacity of 24.8 mmol/L, H2 02 （ concentration of 30% ） adding capacity of 127.5 mL/L and adding 6 times during the to- tal reaction time of three hours. Under the conditions, the COD removal rate could reach to 95%. Finally, using the 1st Opt software to make multiple non-linear fitting, it could establish the mathematic model equation of the COD removal rate of the MWFs by UV/Fenton, and then analyzed and discussed it.
