In order to find the most suitable reactor for ammonia treatment, the volt ampere characteristic and discharge form of DC corona discharge were analyzed. Five kinds of reaction cores were used to carry out experiments, and the electric field intensity inside the reactor was analyzed by computer simulation software to explore the principle of volt ampere characteristics inside the reactor The experimental results show that the factors affecting the removal rate of NH3 are discharge voltage, discharge gap and residence time. Increasing the discharge voltage, decreasing the discharge gap and increasing the residence time are beneficial to the removal of NH3. When the discharge voltage is 23KV, the inlet concentration is 60ppm, the discharge gap is 24mm and the residence time is 3S, the removal rate can reach 73%.
