Study on Hair Dyeing Wastewater by Fenton Oxidation Method

Abstract:

Hair dyeing wastewater is produced in coloring process. Its composition is complicated,in which contains a large number of organic pollutants and high color. Hair dyeing wastewater treatment can be effectively treated by Fenton oxidation method. The experiment results show that hair dyeing wastewater is treated by Fenton oxidation in this thesis. Fenton reagent is affected by hair dyeing wastewater, pH reaction time and many other factors. When raw water COD is 3800mg/L and chroma is 1210 times, by using Fenton oxidation method determine best experimental conditions: concentration of H2O2 is 24.5ml（30%H2O2), pH value is 3.0, nH2O2/nFe2+ is 7, reaction time is 60 min. Under the reaction condition , experimental results show that COD and color removal rates were 91.2% and 93.2% in hair dyeing wastewater by Fenton oxidation.
