DETAILED DESCRIPTION - Treating reverse osmosis concentrated water by using electrochemical water treatment device comprises (1) connecting the electrode mesh and conductive filter membrane of the electrochemical water treatment device with low-voltage direct current, and using peristaltic pump to inject into the electrochemical water treatment device from the water inlet after the reverse osmosis concentrated water is mixed with the advanced oxidizing agent, (2) approaching the surface of the conductive filter membrane driven by the suction of the peristaltic pump after the advanced oxidizing agent and the organic pollutants in the reverse osmosis concentrated water have been fully aerated, combining the advanced oxidizing agent with the reverse osmosis concentrated water and the functional groups or defect sites on the surface of the conductive filter membrane through diffusion on the membrane surface, where the advanced oxidizing agent produces free radicals or active substances with strong oxidizing effect between the gap between the electrode mesh and the conductive filter membrane under the action of the catalyst under the action of an external electric field, oxidizing and decomposing macromolecular organic pollutants into small molecular pollutants, (3) entering the treated reverse osmosis concentrated water to the interior of the membrane module through the conductive filter membrane with the suction of the peristaltic pump, accumulating the treated reverse osmosis concentrate in the diversion bag, flowing out the reverse osmosis concentrated water of the membrane module along the structural gap of the flow channel spacer under the pressure of the peristaltic pump, and flowing out from the water outlet.
