To investigate the reduction of the COD of coking wastewater by electro-catalytic oxidation, the electro-catalytic oxidation pilot-scale experiment was carried out using the coking wastewater treated by A2/O and the coking wastewater treated by A2/O and fenton oxidation. And the modified electrode material (Ti/PbO2) plate was used as anode and 316L stainless steel plate was used as cathode. The effect of electro-catalytic oxidation on the COD removal rate of the two coking wastewater was studied. The experimental results showed that the COD of the coking wastewater treated by A2/O was reduced from 300 mg/L to 165 mg/L and the removal rate reached 45% in the electro-catalytic oxidation unit, and the operating cost was less than 3 yuan/m3. In addition, the COD of the coking wastewater treated by A2/O and fenton was reduced from 130 mg/L to 30 mg/L and the removal rate reached 76.5% in the electro-catalytic oxidation unit oxidation, and the operating cost was less than 6.2 yuan/m3. Furthermore, the COD of the wastewater treated by fenton oxidation and electro-catalytic oxidation was less than 40 mg/L, which suggested that the electro-catalytic oxidation was a reliable, steady and economical method for the deep treatment of coking wastewater.
