曝气条件下微电解-Fenton工艺联合处理模拟染料废水的研究

曝气条件下采用微电解-Fenton工艺处理模拟染料废水。在最佳微电解工艺即铁炭比为45 g∶45 g,pH=3,反应时间为60 min;在Fenton工艺pH值为3,H2O2投加量0.7 mL,反应时间为120 min时,染料废水总脱色率达92%,其色度去除率高于单独微电解工艺时的63%和单独Fenton工艺时的67%。模拟染料废水经微电解及Fenton工艺处理后,废水pH值、Fe2+浓度和色度均发生变化。

Degradation of Stimulated Dyestuff Wastewater by Micro Electrolysis Process and Fenton on Aeration Condition

The simulated wastewater containing Methylene blue is treated by micro electrolysis technology and Fenton on aeration condition.The experimental results show that the decolorization rate can reach 92% under the optimum conditions of micro electrolysis technology at pH=3,iron dosage 45 g,the reaction time 60 min,Fenton technology at pH=3,H2O2 dosage 0.7 mL and the reaction time 120 min,and the decolorization rate is higher than that of separate micro electrolysis(63%) and separate Fenton process(67%).Also the water quality,such as pH,Fe2+ and chromaticity of simulated wastewater change after treatment by microelectrolysis and Fenton process.
