PURPOSE: Provided are an apparatus and a method for electrochemically eliminating nitrogen compounds such as ammonium nitrogen and nitrate (NO3) using an electrolytic cell packed with activated carbon. CONSTITUTION: The apparatus comprises a power supply(1), a voltammeter(2), a pH meter(3), an electrobath(4), an anode electrode(5) made of titanium coated with black lead, a cathode electrode(6) made of titanium coated with iridium, a gas collector(7) for collecting gas generated in the electrobath(4), a sampling instrument(8), and activated carbon with 4x8 mesh, which is filled in the electrobath(4), wherein the anode electrode(5) and the cathode electrode(6) are distanced from each other by 20 mm. The method comprises the steps of preparing an electrolytic cell with electrodes made of titanium and coated with black lead and iridium, respectively, filling an electrobath of the electrolytic cell packed with activated carbon with 4x8 mesh into, introducing water to be treated into the electrobath, and applying power to the electrodes.
