Claim:
An electro-chemical water treatment apparatus comprising: a wastewater collection reservoir that contains wastewater; a wastewater storage retention reservoir that controls a hydrogen ion concentration (pH), an electrical conductivity and an amount of flow of wastewater that is supplied from the wastewater collection reservoir; an electrolyte tank which supplies the wastewater with an electrolyte for making the electrical conductivity of the wastewater in the wastewater storage retention reservoir at an electrical conductivity at which an electrolysis can be achieved; a hydrogen ion concentration (pH) conditioner tank that supplies a hydrogen ion concentration (pH) conditioner for the wastewater in the wastewater storage retention reservoir; at least one selected from an electricity flocculation device, a precipitation device, and a filtering device in order to remove solid matters that exist in the wastewater before the wastewater flows into an electrolyzer; an electrolyzer including an anode plate and a cathode plate through which an anode direct current and a cathode direct current flow, respectively, and a number of electrodes which are arranged as an electrification body between the anode plate and the cathode plate, respectively, and which electrolyses the wastewater supplied from the wastewater storage retention reservoir; wherein the electrodes in the electrolyzer are formed of ceramic electrodes, and the shape of the respective electrodes is formed of one selected from a bead shape, a cylindrical shape, an oval shape, a tetrapod shape, a hexahedron shape and the wastewater passes through a gap that is formed between the number of the ceramic electrodes, wherein each of the ceramic electrodes comprises: a ceramic base material; and a coating layer which is formed of an Ir compound, a Ru compound, and a Sn compound as main ingredients, respectively, on the surface of the ceramic base material, and which is formed of a compound including at least one selected from a Ti compound, a Mo compound, a Ta compound and a Zr compound, in addition to the main ingredients; a frame in which the number of ceramic electrodes are filled in a mono layer; wherein fitting protrusions which are outwardly protruded and fitting grooves which correspond to the fitting protrusions are formed on the outer side the frame, so that the frame is coupled with neighboring another frame, and a number of the electrode arrays are coupled through the fitting protrusions and the fitting grooves; and a controller which grasps state of wastewater, controls level of the wastewater collection reservoir, controls the hydrogen ion concentration (pH), the electrical conductivity and the amount of flow of wastewater in the wastewater storage retention reservoir, and controls level of the electrolyzer and which is connected to the anode plate and the cathode plate to thereby control the electrolysis.
