摘　　要：分别利用芬顿试剂、改性纳米氧化钛协同芬顿试剂处理含2,4-滴废水,并对最佳条件进行了考察。结果表明改性纳米氧化钛协同芬顿试剂的处理效果较好,通过试验得出的最佳条件:改性过程中Cu∶Ti的摩尔比为2∶5;H2O2的体积分数为2 mL/L;FeSO4.7H2O的质量浓度为2 g/L,pH值为5,改性纳米氧化钛的质量浓度为5 g/L;催化反应时间为100 min,此时废水中COD去除率为84.35%。In this experiment,Fenton reagent and modified nano-titanium dioxide combining Fenton reagent were used to treat 2,4-dichlorophenoxyacetic acid wastewater and the optimum conditions were studied.The results showed that the treatment effect of using modifi ed nano-titanium dioxide combining Fenton reagent was better.The optimum conditions were the ratio of Cu and Ti was 2：5 during the process of modification;the dosage of H2O2 and FeSO4.7H2O were 2 mL/L and 2 g/L;pH value was 5;the dosage of modified nano-titanium dioxide was 5 g/L and catalytic reaction time was 100 min,the results showed that the removal rate of wastewater CODCr reached 84.35%.
