Electrochemical treatment method for simultaneous denitrification, carbon removal and detoxification of wastewater

The invention discloses an electrochemical treatment method for synchronous denitrification, carbon removal and detoxification of wastewater, belonging to the field of wastewater treatment. Accordingto the invention, the filtered waste water is subjected to ring opening treatment through a first chamber of an electrochemical reactor, and then the waste water treated in the first chamber of the electrochemical reactor is subjected to synchronous denitrification, carbon removal and detoxification treatment through a second chamber of the electrochemical reactor; then the wastewater treated in the second chamber of the electrochemical reactor is refluxed to the front end of the first chamber for refluxing and circulating treatment to obtain wastewater after simultaneous denitrification, carbon removal and detoxification. The electrochemical treatment method realizes synchronous denitrification and detoxification treatment of the wastewater on the basis of removing COD pollutants by selecting suitable matched ele
