In order to solve the problem of ammonia nitrogen pollution, three-dimensional electrode electrochemical oxidation technology is utilized to transform ammonia nitrogen. The influence of influent pH, power supply and electrolyte concentration on ammonia nitrogen removal by three-dimensional electrode method and its mechanism were discussed by single factor variable analysis. The particle electrode by emission scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The results show that the removal efficiency of ammonia nitrogen by three-dimensional electrode is higher than that by two-dimensional electrode. When the aqueous solution is neutral, the direct and indirect oxidation reactions of ammonia nitrogen can reach the best state, and the removal efficiency is the highest. Within a certain range, the electrolytic efficiency will increase with the increase of electrolytic voltage and electrolyte concentration. The reduction of electrode spacing in a certain range can enhance the direct oxidation of ammonia nitrogen and improve the electrolysis efficiency of ammonia nitrogen. Under the conditions of pH 7, power supply voltage 14 V, electrolyte concentration 0.1 mol/L, electrode spacing 1 cm, electrolytic time 50 min, ammonia nitrogen can be completely removed from the three-dimensional electrode
