Oxidative Hair Dye

The amount of hair dye wastewater largest stage formed by oxidative hair dye in terms of quantity and quality, there is a serious pollution problem in the aquatic environment. Through analysis of the main component of hair dye to verify the use of activated carbon adsorption - Coagulation - potassium permanganate oxidation technology of wastewater treatment which is effective measures.According to different types of hair dye,about 80% of the market demand oxidative hair dye brown was selected to study. The results showed that the COD of 2427mg / L, the chromaticity of the hair 1000 times wastewater using 1300mg / L activated carbon adsorption treatment alone, the removal rates were 37.79%, 18.29%; in this condition and 140mg / L of mixed PAC condensate combined treatment, removal rates were 90.09%, 90.56%; potassium permanganate solution 70mg / L continues oxidation treatment, the removal rate reached 90.34 %, 97.37 %.
