摘要
通过臭氧氧化法处理酸性橙、直接嫩黄和直接玫红溶液模拟的印染废水,考察了反应时间、温度、pH、浓度等因素对处理效果的影响。结果表明,3种染料都随着pH的增加处理效果越好,在pH=13时,臭氧对酸性橙、直接嫩黄、直接玫红的去除率分别是90.9%,91.1%,89.7%;3种染料在浓度为500 mg/L时的去除率都比1 000 mg/L时候略大,说明在污染物处于低浓度下,臭氧氧化的效果更好;3种染料的最佳处理温度也都在35℃左右,温度对直接嫩黄和直接玫红的影响并不是很大,对酸性橙染料的去除效果影响较大。
Through the treatment of acid orange, direct yellow and direct rose dye wastewater by ozone oxi- dation. Discussing the influence of reaction time, temperature, pH and concentration, etc. on treatment effect. The results show that：For the three kinds of dyes, the greater the pH,treatment effect is better. In the pH = 13, the treatment efficiency of acid orange, direct yellow and direct rose by ozone is 90.9%, 91.1% ,89.7%. In the concentration of 500 mg/L of the removal rate is slightly larger than 1 000 mg/L. It states that the effect of ozone oxidation is better when pollutants are in low concentrations. The best pro- cessing temperature is 35℃. The effect of temperature on direct yellow and direct red is not great, but it dose great influence on acid orange.
