AI Technical Summary
Existing technologies are insufficient for efficiently removing nitrates, ammonia nitrogen, and organic pollutants from nitrogen-containing organic wastewater in a single electrochemical reactor, and combining multiple reactors increases treatment costs and equipment maintenance difficulties.
A three-dimensional electrochemical reaction device is used, which includes an electrolytic cell, a cathode plate, a cation exchange membrane, a cation exchange packing material, an anion exchange membrane, and an anode plate. Nitrate, ammonia nitrogen, and organic pollutants are removed simultaneously in a single electrolytic cell through zoned reactions. Ammonia nitrogen is adsorbed by the cation exchange packing material, and active chlorine is generated at the anode to oxidize organic pollutants and convert ammonia nitrogen into nitrogen gas.
This method achieves efficient removal of nitrates, ammonia nitrogen, and organic pollutants from nitrogen-containing organic wastewater in the same electrolytic cell, avoiding the use of chemical agents, reducing treatment costs, and improving wastewater treatment efficiency.
