Background of the Invention

As the usage of water increases and the air and water pollution intensify day by day, the necessity of treating waste water and reusing water is increasing. That is, efficient sterilization techniques such as discharged water or upstream water have been developed and applied, and conventional chlorine disinfection, UV disinfection and ozone disinfection are typical examples. UV disinfection has recently been intensively studied as a method of disinfection by ultraviolet rays, but UV disinfection has no residual effects, excessive facility and maintenance costs, relatively difficult to cope with fluctuations in the flow rate of treated water, and turbidity in the treated water. , Solid suspended solids (SS), the pigment is a high treatment effect is very low. In addition, since the light recovery rate of the microorganisms self-recovering the DNA damaged by the UV is high, it is difficult to be sure that the microorganisms had a definite disinfection effect in the field. Ozone disinfection method is a method that can obtain a large disinfection effect with a strong oxidizing power, but low solubility of ozone, high facility cost and operation cost, and needs a post-treatment facility to prevent the outflow of ozone generated in the water treatment process. In addition, ozone disinfection has not been clearly validated for the treatment by-product stability. Chlorine disinfection is the most widely used method of disinfection of water. However, the chlorine disinfection method produces a strong toxic by-product, such as THM, and has a disadvantage in that the disinfecting effect is not great in the case where oil, grease or colloidal material having low density is contained in the water. In addition, the bactericidal power is limited only to bacteria having high sensitivity to chlorine.

Conventional patents related to disinfection using electrolysis include 'water purifier sterilization device' (Korean Patent Application No. 10-0233775, 1999.09.14) and 'water electrolytic disinfection method and electrolytic disinfection device' (Korean Patent Application No. 10- 2001-7012714, 2001.10.05). However, the patent has a problem that the damage of the electrode easily occurs by arranging the plate-shaped electrodes in a row.

Accordingly, the present inventors have made diligent efforts to solve the shortcomings of the prior art, and as a result, the plate-shaped electrodes arranged in a line in the electrolytic sterilization apparatus can be mounted in the electrolytic sterilization apparatus more easily by combining the nut and the round bar, and the coupling part The present invention was completed by confirming that the inter-electrode spacing was maintained.

SUMMARY OF THE INVENTION The main object of the present invention is to provide an assembled electrode set in which the electrode set is provided in the electrolytic sterilization apparatus more easily, and the electrical efficiency is kept constant.

In order to achieve the above object, the present invention, in the electrode set mounted on the electrolytic sterilization apparatus for inactivating the microorganisms remaining in the treated water, an electrode pair having two sets of two electrodes of different network or plate-like polarity An electrode unit 20 arranged horizontally; A connection part 30 composed of at least one round bar 31 vertically penetrating the electrode and coupled to upper and lower sides of the electrode, and nuts 32 fixing both ends of the round bar coupled to the upper and lower sides of the electrode; Coupling part 40 consisting of a conductor coupling 41 for maintaining the inter-electrode spacing arranged in a row and preventing a short circuit and an insulator coupling 42 insulated outside of the conductor coupling formed on both sides of the electrode. It includes, wherein the two or more electrode parts are arranged in a multi-stage, and provides a prefabricated electrode set, characterized in that the up and down electrode parts are arranged to have a different polarity.

The material of the electrode should be oxidation resistance in order to have durability on the oxidizing material generated during electrolysis, and should be composed of an insoluble material so that stability can be maintained as an electrode, and it is preferable to use an electrically conductive material. In order to implement the electrode using the polarity switching method more desirably, the electrode part disposed inside the electrolytic sterilization apparatus should be made of the same material for the positive electrode and the negative electrode so as not to be damaged even when the electrode is polarized. . Conventionally, in order to manufacture an electrode for electrolysis, it was used by coating a nickel or platinum on the conductor material, but the nuthenium or platinum generates too much residual chlorine during electrolysis to treat the treated water and discharge it into seawater As a disadvantage, it is preferable that the electrode used for the electrolysis of the treated water is coated with iridium oxide on a titanium material. The spacing of the electrodes in the electrode portion is about 10 mm to prevent the spacing of the electrodes from being too dense or wide to reduce the efficiency of electrolysis.

At least one round bar penetrates the electrode vertically, and the round bar is coupled to the upper and lower sides of the electrode and fixed with titanium nuts at both ends of the round bar to form a single electrode set. At this time, tabs formed at both ends of the round bar are fitted to the nut, and the round bar is made of copper or aluminum, and preferably coated with titanium. In order to maintain a gap between the electrodes and to prevent a short circuit, the plurality of electrode units in the electrolytic sterilizer may be mounted and used in the spacer and the inner case. Since the spacer and the inner case should be insulated, it is preferable to manufacture the PVC-based insulating synthetic resin, and the treated water is configured to pass through the electrode inside the case.

The coupling part includes a conductor coupling to maintain a gap between the electrodes with the connection tools of the electrodes arranged in a line, and prevent a short circuit, and an insulator coupling insulated outside of the conductor coupling formed on both sides of the electrode. In order to prevent a short circuit, the conductor coupling connects the electrodes arranged in a line, and maintains the gap between the electrodes, and the material of the conductor coupling is preferably titanium, and an insulator coupling insulated outside of the titanium coupling. The gap between the electrodes is maintained, and the material of the insulator coupling is preferably PVC or Teflon. In addition, the conductor coupling and the non-conductor coupling connecting the electrode to the round bar are alternately arranged on the round bar penetrating the upper electrode and the round bar penetrating the lower electrode. The anodes and the cathodes are alternately arranged in the electrode arrangement between the electrode sets arranged alternately with each other and arranged in multiple stages. In the electrode arrangement of the round bar fixed to the electrode set, the anode and the cathode are alternately arranged with each other, and the electrode arrangement of the rod between the electrode sets is alternately arranged with the electrodes opposite to each other to maintain a constant interval between the electrode portions.

Figure 3 shows the configuration of the assembled electrode set according to the present invention in a multi-stage arrangement, showing the arrangement of electrodes and the electrode arrangement of the round bar. In the electrode set, two or more of the electrode parts are arranged in multiple stages, and upper and lower electrode parts have different polarities, and in the assembled electrode set, an electrode pair including two plate or mesh electrodes having different polarities is horizontal in the flow direction.
