The invention provides an electrochemical-membrane separation water treating device, a treating method and an application thereof. The electrochemical-membrane separation water treating device comprises a reaction tank, wherein the reaction tank is internally provided with a membrane component; one side of the membrane component is provided with a sensing electrode and an anode plate from inside to outside in a manner of being parallel to the membrane component; the other side of the membrane component is provided with a cathode plate parallel to the membrane component; the anode plate and the cathode plate are connected with an external power supply; a water inlet is arranged at one side of a main body of the reaction tank; and a water outlet of the membrane component is arranged on the main body of the reaction tank and is connected with the membrane component. The electrochemical-membrane separation water treating device, the treating method and the application provided by the invention have the advantages that electric-field effect, electrochemical oxidation, electroflocculation and electroflotation are integrated, and by the action of electrooxidation and electroflocculation, the structure of pollutants is changed, the size of particles is adjusted, and a hydrophilic and porous filter cake layer is formed on the membrane surface, so that the pollution to the membrane is reduced; and the solid-liquid separation is carried out by membrane filtration, so that the quality of discharged water is further improved.
