Abstract Electrode particle string, which has no short-circuited current, was used as the filling material of three-dimensional electrode to better reveal the characteristics of electrochemical reaction. The results revealed that the removal of ammonia during electrochemical reaction involved two steps: before 80min, it was mainly caused by the electrochemical oxidation reaction between ammonia and hydroxyl radicals generated at the cathode particle electrode; after 80min, small amount of normalized reactions provided synergy effect to achieve better removal rate. Experimental results also showed an improvement of ammonia removal rate with the increase in cell voltage. The highest removal rate was achieved under pH 10 with the voltage of 25V.
