By choosing electrochemical oxidation of simulated high strength ammonia wastewater, and investigating the effects on ammonia removal of different electrode materials, current density, chloride concentration and ph and other factors, the ex- periment shows that high current density and chloride concentration profit for the removal of ammonia nitrogen. Electrolytic oxidation condition goes as follows: current density is 15 mA/cm2and chloride concentration is 4 000 mg/L using Ti/RuOz-IrO2 electrode as 'after electrolysis for 2 hours, ammonia nitrogen removal rate will
