The invention discloses a method for treating antibiotic resistance genes in medical wastewater or sludge generated by a medical wastewater treatment process, and belongs to the field of sewage treatment. A treatment device for the antibiotic resistance genes in the medical wastewater is a bioelectrochemical system, and is specifically characterized in that: a nano CaO2 loaded graphite felt electrode is used as an anode, a carbon fiber brush is used as a cathode, two electrode chambers are separated by a cation exchange membrane, a potassium dichromate solution is used as a catholyte, the medical wastewater or sludge generated by a medical wastewater treatment process is used as an anode substrate, the cathode and the anode are connected through a lead to form a complete circuit, and the bioelectrochemical system performs closed-circuit operation. The nano CaO2 electrode reacts with water to generate hydroxyl radicals, ARGs in sludge generated in the medical wastewater treatment process are reduced, and parti
