Field of the Invention The present invention relates to a circulating water purification system and method, and more particularly, to a circulation purification system and method for circulating used water to be filtered and sterilized and treated with a plasma product.
In general, a method widely used to purify contaminated water from agriculture processing facilities is filtration, sterilization with ozone sterilization, ultraviolet sterilization, chlorine, and electrolytic water.
The filtration treatment method is capable of removing fine suspended particles, but is not suitable for sterilizing microorganisms contained in contaminated water. Therefore, the filtered water is sterilized by ozone sterilization, ultraviolet sterilization, chlorine, electrolytic water, or the like.
However, in the case of ozone water, scale is inserted into the discharge tube of the ozone generator, so that the ultraviolet sterilization is sterilized only at the surface, and the electrolytic water is discharged at a high concentration. In addition, such a sterilization method is difficult to use because the facility installation cost and the operation cost are high, and when the various processes are used in combination, the apparatus becomes complicated and operation conditions and operation of the apparatus become difficult.

The collecting tank may include a pump for transferring wash water.
The pump may be to supply wash water at a pressure of 200 L / min.
The filtration device may include a primary filter device for filtering wash water and a secondary filter device for precipitating the filtered wash water.
The filtration device may be to filtrate fine suspensions of at least 1 micrometer.
The plasma sterilizer includes a plasma sterilizer having a washing water inlet through which the washing water is introduced and a washing water outlet through which the washing water is sterilized, a gas inlet formed at one side of the plasma sterilizer, And a plasma generator disposed inside the plasma sterilizer and connected to the gas inlet and the gas outlet to generate ozone and sterilizing light.
The plasma sterilizer may include a gas pipe having one side connected to the gas discharge port and the other side connected to the washing water inlet and a venturi part corresponding to a connection part between the gas pipe and the washing water inlet.
The control unit may include a plasma sterilizer control unit for controlling the plasma sterilizer and a water supply controller for controlling the pump.
A method for carrying out an embodiment of the present invention is characterized in that washing water collected in a collecting tank is transferred to the filtration apparatus by the pump, the washing water transferred to the filtration apparatus is filtered through the first filter apparatus, The washing water is settled through the second filter unit, the washing water having passed through the filtering unit flows through the washing water inlet and is sterilized by sterilizing light, the sterilized washing water is discharged through the washing water outlet And circulating the discharged wash water to the collecting tank.
The step of discharging the wash water through the discharge port may include mixing the wash water discharged through the discharge port with the ozone gas generated in the plasma generating part and discharged through the gas discharge port in the venturi part.
According to another aspect of the present invention, there is provided a circulating water purification method comprising: a step of transferring washing water collected in a collecting tank to a filtration apparatus by a pump; washing water transferred to the filtration apparatus through a first- Wherein the filtered water is settled through a secondary filter device, washing water having passed through the filtering device flows through the washing water inlet and sterilized by sterilizing light, and the sterilized washing water is supplied to the washing water outlet And discharging the discharged wash water to the collecting tank.
Wherein the washing water is introduced into the plasma sterilizing unit through the washing water inlet and the sterilizing light is supplied to the plasma sterilizing unit through the washing water inlet and the ozone generated in the plasma generating unit, And mixing in the venturi part.
The washing water collected in the collecting tank can be circulated for at least 30 minutes to less than 1 hour.
The circulating water purification system according to the present invention reduces the cost of using the washing water by recycling the washing water used in the agricultural processing facility and circulates and cleanses the water several times. By cleaning the processed food by removing the unhygienic bacteria contained in the washing water, And can provide a safe washing food.
It also prevents the release of high concentrations of sterile water, thereby preventing environmental contamination due to sterile water release and reducing the cost of treating sterile water.
