Study on Industrial Wastewater Treatment by Way of Electrolytic Anode Catalysis

The industrial wastewater containing high-concentration chlorophenol was tested and studied as an instance to make sure of the feasibility and effect of treating wastewater containing high-concentration organic compounds by way of electrolytic anode catalysis. A test was carried out in a reaction tank under 8 V and 45 mA/cm, where the values of COD in the simulated and washing wastewater containing high-concentration chlorophenol were 1388, 2343 and 1685 mg/L and the wastewater was treated for 2 hr and, as a result, 68% and 59% were removed, respectively. The results showed that the electrolytic anode catalysis is effectively feasible to the treatment of industrial wastewater containing high-concentration organic compounds, and it is technologically simple in operation and available to automatic control. It will have good prospects in iron and steel industry for water washing.
