Abstract: The present invention discloses a method and device for removing chloride ions in desulfurized wastewater by electrochemical coupling. In the device, an electrolyte tank is used as a separator in a separation process and as an electrode regenerator in an electrode regeneration process; two electrodes are a hydrogen evolution electrocatalysis function electrode and an electrochemically switched ion exchange (ESIX) function electrode respectively, and the electrodes are connected with each other by a wire; two DC circuits have opposite electric field directions and are alternately used in the separation process and the electrode regeneration process respectively; the bottom of the electrolyte tank is provided with a purified high-concentration chloride ion wastewater inlet and a flocculation product outlet, and the top is provided with a dechlorination treatment water outlet and a hydrogen collecting port; and in the electrode regeneration process, the electrolyte tank is connected to an electrode regeneration liquid storage tank through a pump and a pipeline. In the present invention, by utilizing the synergistic reinforcement of reactions of an anode and a cathode, the chloride ion removal efficiency and energy utilization efficiency can be improved, and finally the chloride ions in wastewater are present in flocculation products in a solid form, which facilitates recycling.
