The cold plasma processing unit 140 receives the water after the foreign material has been removed through the foreign material removal unit 120 , and the result value checked through the water quality check unit 130 , that is, the pH concentration of the water, the water temperature, the water pressure, and the air in the tank. According to water quality information related to pressure, etc., washing water used for washing food materials such as vegetables, fruits, fish, etc., general water used for swimming pools or fountains, agricultural water for plant or crop cultivation, or breeding of fish and shellfish in aquariums or fish farms It generates active radicals, including cold plasma for sterilization or purification, and to adjust the pH concentration of water to a value within a preset reference range so as to be usable in fishery water, etc. At this time, the cold plasma processing unit 140 receives the water after the foreign matter has been removed through the inlet 141a, and generates a high voltage discharge in water using a cold plasma technology of 1500V, 21KHz to generate a cold plasma by ozone, OH radicals, A large amount of active species including water electrons are dissolved in water, and cold plasma treated water electrically charged by plasma energy is generated and discharged to the water outlet 141b. At this time, as illustrated in FIG. 2 , in the cold plasma processing unit 140 , the lower partition wall 142a with an open upper part and the upper partition wall 142b with the lower part open are alternately formed inside the water tank so that the inner space of the water tank is divided into a plurality of spaces. Since the separation water tank 141 separated into the detailed space 143a-143c is formed, the water introduced into the water tank through the water inlet 141a is bent up and down by the lower partition wall 142a and the upper partition wall 142b. Water can be discharged to the water outlet 141b sequentially through the detailed spaces 143a-143c of the separation water tank 141 . In addition, in the cold plasma processing unit 140 of the present invention, a plurality of plasma torches 144a-144e are installed in the water in each detailed space 143a-143c of the separation water tank 141, so that at least 1 with cold plasma technology of 1500V, 21KHz Since it is possible to generate by generating a high voltage discharge more than once, when the cold plasma processing unit 140 of the present invention is passed through, a large amount of active species including ozone, OH radicals, and electrons are dissolved in the water and are electrically generated by plasma energy. It is possible to obtain treated water of high radical solubility charged with

Through this process, the treated water from the water outlet 141b of the cold plasma processing unit 140 is transferred to the ion watertight contact unit 150, and the plasma generated by the cold plasma processing unit 140 in the ion watertight contact unit 150.

The incoming plasma treated water is directly supplied and stored under the water surface in the water tank, and thus, it is possible to prevent in advance the forced separation of the liquid and gas of the plasma treated water by a fall.

In addition, using the pressure/flow control valve 166 connected between the pipe on the outlet side 151b of the ion watertight contact part 150 and the treated water inlet pipe 162, the gas-liquid separation unit 160 flows into the water tank 161 It becomes possible to adjust the pressure or flow rate of the treated water.

On the other hand, cold plasma treated water supplied directly under the water surface in the water tank and stored is converted into cold plasma sterilization water by separating liquid and gas during the storage process, and the separated gas is an exhaust port 161c formed on the upper surface of the water tank 161 . ) and the exhaust pipe 164 are discharged to the ozone removal unit 170, and the cold plasma sterilization water from which the gas is separated is stored in the water tank and the drain pump 181 of the reducing unit 180 is operated when the pump The sterilizing water is sucked into the pipe from the bottom suction port 163a formed in the discharge pipe 163 by the pressure, and can be discharged to the outside through the discharge port 161b formed at the lower side of the side wall of the water tank 161.

In addition, in the gas-liquid separation unit 160 as described above, an outlet 161d for discharging the water inside the water tank 161 to the outside at a water level of a certain height is formed at a predetermined height above the side wall of the water tank, so that the same Cold plasma treatment through the overflow pipe 165 and the outlet 161d extending to the bottom inside the water tank 161 when the water level inside the water tank rises above a certain height if the drainage through the outlet 161b is not performed properly By draining the water to the outside, it is possible to maintain the water level inside the water tank 161 at a predetermined height.

On the other hand, since the exhaust ozone removal unit 170 composed of an activated carbon filter is installed in the exhaust port 161c of the gas-liquid separation unit 160, the exhaust ozone remaining in the gas separated from the water in the gas-liquid separation unit 160 is discharged. Air removed by the ozone removal unit 170 and purified can be discharged, and in the reduction unit 180 connected to the sterilizing water discharge pipe 163 of the gas-liquid separation unit 160 , the gas is removed from the gas-liquid separation unit 160 . By reducing a large amount of the cold plasma sterilizing water after the separation to the water tank 100, it is possible to obtain a large-capacity cold plasma sterilizing water that can be used as washing water, general water, agricultural water, or fishing water.
