摘　　要：采用Fenton试剂处理酸性玫瑰红B染料废水,考察了FeSO4投加量、H2O2投加量、pH值和反应时间对处理效果的影响,研究了原水的氧化还原电位和TOC的变化规律,评价了它的可生化性。结果表明,最佳pH值为3,FeSO4的适宜投加量为8mmol/L,H2O2最佳投加量为50mmol/L,此时COD去除率和脱色率分别为77.1%和92.8%,处理后该染料废水的可生化性大大提高。Fenton reagent was used to treat wastewater of Acid Rose Red. The effect of the dosage of FeSO4 and H2O2, pH and reaction time on removal efficiency were investigated. Redox potential of solution and rule of TOC change were discussed, too. The result showed that the optimum pH was 3, and the optimum dosage of FeSO4 and H2O2, were 8mmol/L and 50mmol/L, respectively. Meanwhile, the COD and color removal rate were 77. 1% and 92. 8%, respectively, and wastewater of Acid Rose Red was biodegradable.
