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.
