摘要
传统的芬顿反应必须反复调节废水pH,对其进行了优化,利用吸附材料作为酸的载体,在其表面发生芬顿反应来减少酸碱的用量。并利用该优化方法对模拟的亚甲基蓝染料废水进行脱色研究,实验表明:酸性沸石的投加量10 g/L,FeSO_4·7H_2O投加量150 mg/L,30%H_2O_2投加量3mL/L,反应时间30 min,最佳脱色率为99.4%。
The waste water p H must be repeatedly adjusted in traditional Fenton reaction,which was optimized in this paper. The adsorption material was used as the carrier of acid,and the Fenton reaction was taken on the surface to reduce the amount of acid and alkali. The degradation of methylene blue was studied using the optimization method. The result shows that the decoloring rate can reach as high as 99. 4% with conditions,the zeolite dosage 10 g/L,the dosage of FeSO_4·7H_2O150 mg/L,the H_2O_2 dosage 3 mL/L,reaction time 30 min.
