Method for removing atranex in water

This invention discloses a medium-blockage discharge method for removing atrazine from water. The method comprises: (1) placing the water to be treated between a high-voltage electrode and a ground electrode with a medium in between; (2) applying high-frequency current to the high-voltage electrode, and discharging with the blockage of the medium. The discharge voltage peak, current peak and current frequency are 8000-12000 V, 20-50 mA and 2.5-30 kHz, respectively. The distance between the medium and the water surface is not more than 20 mm. The method has such advantages as high efficiency, simple process, high controllability, mild reaction conditions and easy operation.
