▎ 摘　　要

NOVELTY - Treating high salt and high ammonia nitrogen refractory organic wastewater comprises (i) conveying wastewater to anode chamber of microbial electrolysis cell for anaerobic ammonia oxidation and autotrophic denitrification, (ii) denitrifying wastewater, and conveying it to electrochemical advanced oxidation unit to degrade refractory organic matter, and (iii) conveying effluent of electrochemical advanced oxidation unit to cathode chamber of microbial electrolytic cell to reduce perchlorate and chlorate, and reducing concentration of chlorine by-products in wastewater. The anode electrode of anode chamber of microbiological electrolytic cell is porous graphene electrode, and the cathode electrode of cathode chamber is carbon fiber electrode. USE - The method is useful for treating high salt and high ammonia nitrogen refractory organic wastewater. ADVANTAGE - The method: realizes bio-anode autotrophic denitrification and bio-cathode (per)chlorate reduction to form electrochemical advanced oxidation treatment of high-salt and high-ammonia-nitrogen refractory organic wastewater by microbial electrolytic cell; is economical, and environmental-friendly; and has high efficacy.
