Device and method for treating high-concentration phenol-containing wastewater by combining centrifugal extraction and electro-catalysis

The invention belongs to the field of industrial wastewater treatment, and discloses a device and a method for treating high-concentration phenol-containing wastewater by combining centrifugal extraction and electro-catalysis. The high-concentration phenol-containing wastewater is treated through centrifugal extraction, and efficient dephenolization of the phenol-containing wastewater with different concentrations and treatment flows is realized by adjusting the components, flow and oil-water flow ratio of the extraction agent; the extracted low-concentration phenol-containing wastewater is jointly treated by utilizing an electro-catalysis technology, a novel iron-based copper-plated electrode is prepared to replace a pure copper electrode, the electrolysis cost is greatly reduced, the iron-based copper-plated electrode and a ruthenium-iridium anode generate a synergistic catalysis effect, the wastewater is electrolyzed in a flowing state, and phenol concentration gradient change is formed near the electrode;
