摘要
采用UV/Fenton高级氧化技术对酸性红B模拟废水进行处理,当进水浓度为400 mg/L时,确定了各影响因素的最佳投加量:H2O2投加量为2 mL/L,Fe2+投加量为0.08 g/L,最佳pH值为4;并采用一级动力学公式对酸性红B降解速率进行拟合,研究了反应条件对速率常数的影响。最后通过对单独UV法、单独Fenton法和UV/Fenton法3种处理方法效果的比较,发现UV与Fenton试剂具有协同作用。
UV/Fenton was used to degrade the acid red B-containing wastewater. Studies show that when the initial concentration was 400 mg/L, the best parameters of the reaction were： H2O2 dosage 2 mL/L, Fe^2＋ dosage 0.08 g/L, pH value 4. The first order kinetic model was also given to fit the relationship between degradation rate constant and reaction parameters. Finally, through comparing the results of the three kinds of reaction systems, studies show that UV and Fenton reagents have a synergistic effect.
