摘要

The color elimination of real tea wastewater by the electrocatalytic system was investigated. The electrocatalytic system composed IrO_2 electrode as the anode and DSA electrode as the cathode under the current density of 40 mA cm~(-2). Various concentrations of NaCl and wastewater volumes were tested to understand their effects. For the effect of NaCl addition, the color removal efficiency increased 25% under the condition of NaCl addition. The relatively proper operation was 0.25 M NaCl and 1.0 liter wastewater, which caused the color removal efficiency up to 85% within 10-min treatment. Based on this color removal efficiency, the tea wastewater of 1.0 L consumed the electricity of 0.03KWh.
