Removal of ammonia nitrogen from micro-polluted water by electrocoagulation method
Removal efficiency of ammonia nitrogen and its influencing factors were investigated under different reaction conditions.The mechanism was also studied additionally.The results showed that the removal efficiency of ammonia nitrogen by electrocoagulation method was quite satisfactory and increased by the elevation of current density and electrolytic time.High acid or alkaline conditions were all adverse to the removal efficiency while alkalescene condition was the most appropriate.Sediment time only had slight impact on the removal efficiency.Under the conditions of current density of 3.42 mA/cm2,electrolytic time of 30 min,initial pH of 7.0-9.0,sediment time of 20 min,the best removal efficiency of ammonia nitrogen for micro-polluted water was achieved.
