ABSTRACT
Carmine wastewater was treated by electrochemical oxidation. The effects of single and double cathodes, electrolyte type, wastewater concentration, and current on the decolorization rate of carmine wastewater were discussed. The experimental results showed that the decolorization rate was 97.19% for 0.10 mol/L NaCl, and when the concentration of wastewater was 0.2000 g/L with 1.0 L, the pH value was 6.10, the aeration rate was 0.80 L/min, the electrode material was 316 L stainless steel with 40 mesh, the electrode distance was 2.0 cm, and the electrolysis time was 40.0 min.
