Fenton法处理刚果红染料废水的研究

Study on reducing Congo red in dying wastewater by Fenton reagend

采用Fenton法和超声波加过氧化氢法对刚果红染料废水进行处理.采用Fenton法,在pH值为3,过氧化氢浓度为0.13mol/L,Fe^(2+)浓度为0.0031mol/L,染料质量浓度为10mg/L条件下,脱色率为95%;采用超声波加过氧化氢法,脱色率为10.4%.通过两种方法的对比,Fenton法处理刚果红染料废水效果较好.

In this paper, two methods of Fenton reagend and ultrasonic with H2O2 are used for reducing Cone red in dyeing wastewater. In the same experimental condition, pH value is 3, 0.13 mol/L H2O2, 0. 003 1 mol/L Fe^2＋ and 10 mg/L dye, the decolorization ratio is 95% and 10.4%, respectively, by Fenton reagend and ultrasonic with H2O2. Comparison between the former and the latter, the former is better than the latter.
