Technology for processing high-concentration organic wastewater in composite electrochemical method

The invention relates to a technology for processing high-concentration organic wastewater in a composite electrochemical method, which comprises the main four steps of: pH adjustment, multidimensional electrocatalytic oxidization processing, micro coupling electric fenton reaction oxidation processing and coagulating sedimentation processing. The invention has the technical advantage that the technology has good breaking, chain scission, degradation effects to benzene ring organics, heterocyclic organics, polycyclic organics, macromolecule organics and sustaining organics, which have the most difficulty to degradation. Besides, the technology has no obvious selection to various kinds of high-concentration organic wastewater, has broad-spectrum processing effect, and is an effective measurement for pre-processing to high-concentration organic wastewater having difficulty to degradation. The invention is characterized in that the technology uses second-grade electrochemical processing equipment to realize thir
