| titleOfInvention | Automatic control method for dissolved oxygen in pressurized tank type water with sterilization means |
| abstract | (57) [Summary] (with correction) [Problem] To provide a method for controlling inexpensively and accurately the amount of dissolved oxygen dissolved in water, which is indispensable for life activity. SOLUTION: Nitrogen gas and oxygen gas are mixed in a gas mixer 23, sent to a pressure tank 21, dissolved in water, and sent to a closed tank 11. The accumulated water in the closed tank 11 is circulated by the circulation pump Then, activation processing is performed by the infrared irradiation device 15 and the gas is injected by the gas injection nozzle 16. The mixture ratio of both oxygen and nitrogen gas is adjusted using the detection value of the oxidation-reduction potential / dissolved oxygen detection sensor 30 in the closed tank 11. The water remaining in the sealed tank 11 is filtered by the filtration pump 35 into the ultraviolet irradiation device 3. 2 to sterilize, pass through a ceramic cylinder 33 to adjust the oxidation-reduction potential to a predetermined value, pass through a filtration device 34 to filter sludge and the like, and return to a closed tank. The treated water is stored in a stock tank 4 which is automatically adjusted to a predetermined amount, and responds to occasional use. |
