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%。
Two and four-drop wastewater was treated with Fenton reagent and modified nano titanium oxide in combination with Fenton reagent respectively, and the best conditions were investigated. The results show that the modified nano-titanium oxide with Fenton reagent treatment is better, the best conditions obtained through the experiment: the molar ratio of Cu: Ti in the modification process is 2: 5; the volume fraction of H2O2 is 2 mL / L ; The mass concentration of FeSO4.7H2O was 2 g / L, pH value was 5, the mass concentration of modified nano-titania was 5 g / L and the catalytic reaction time was 100 min. At this time, the COD removal efficiency in wastewater was 84.35%.
