事により循環養液を常に病菌濃度を低く保持させる。Function: With the above-described configuration, the present invention takes a part of the nutrient solution from the nutrient solution supply system route from the nutrient solution tank of the circulating type hydroponic cultivation device to the cultivation bed, and converts it into ultraviolet rays and generates electricity using the ultraviolet rays. By sterilizing the circulating nutrient solution with ozone and then returning it to the nutrient solution tank, the concentration of pathogenic bacteria in the circulating nutrient solution is always maintained at a low level.

。Further, by foaming and discharging the ozone-containing air from the lower end of the water pump in the sterilizer, an upward flow containing air bubbles is generated in the nutrient solution in the water pump, and the nutrient solution is pumped into the nutrient solution tank. Furthermore, this sterilizer is controlled to operate intermittently at a rate of approximately 1 to 6 circulation volumes of total nutrient solution per day (the amount of treated solution passing through the device is 1 to 6 times the total amount of nutrient solution), and In order to maintain good ultraviolet irradiation to the water pumping tube using countercurrent flow, a mechanism is driven that mechanically wipes the ozone generating tube outer tube.

接触部には刷毛を有する払拭機構となっている。Embodiment FIG. 1 shows a sectional view of a nutrient solution sterilizer according to an embodiment of the present invention. In Fig. 1, 1 is the nutrient solution tank, 2 is the nutrient solution supply pipe, and 3 is 253. of 1 ooV, 20W.
An ultraviolet light emitting tube with a 7 nm ultraviolet peak, 4 is an air blower, 6 is an air blowing tube that blows air into the ozone generating tube 6, 7 is a blowing tube that blows air containing ozone from the ozone generating tube 6, 8 is a mI blowing tube An air pipe 11 is for discharging the ozone-containing air coming out of the pipe 7 from the air pipe 10 at the bottom of the water pump 9, and 11 is for injecting the nutrient solution pumped up by the air lift into the perfume tank 1. A water inlet, 12 is a control device for synchronizing and intermittently driving the proa 4 and the ultraviolet light emitting tube 3, and 13 is a blade on the outer periphery of the ozone generating tube 6 to wipe the outer wall of the ozone generating tube 6 using the upward flow of the nutrient solution pumped intermittently. A wiping mechanism with a brush is provided at the part that contacts the outer wall of the ozone generating tube.

払拭しながらオゾン発生管下端で停止する。When the glower 4 and the ultraviolet light emitting tube 3 are driven twice a day and each night for three hours, and air is supplied around the ultraviolet light emitting tube 3, part of the oxygen in the air is converted into ozone and mixed air τ is generated. It is discharged from the air cone 1o at the bottom of the water pump 9. As a result, bubbles are generated in the nutrient solution in the water pumping cylinder 9,
This generates an upward flow. Due to the upward flow, the blades of the wiping mechanism 13 raise the wiping mechanism 13 little by little, and the brushes of the wiping mechanism 13 wipe the outer wall of the ozone generating tube 6, thereby preventing a decrease in the transmittance of ultraviolet rays. - When the operation of the blower 4 and ultraviolet luminous tube 3 is stopped for a fixed period of time by the operation of the control device 12, the wiping machine 13, which had risen to the upper liquid level, rotates and descends under its own weight, and at that time the luminous tube 3 returns again. While wiping the wall, stop at the bottom end of the ozone generator tube.

By pumping up water and returning it to the circulation system, and by performing the pumping intermittently, it is possible not only to save energy, but also to utilize the intermittent operation of rising air bubbles to reduce the penetration of ultraviolet rays caused by contamination such as algae that forms on the outer wall of the ozone generating tube. It is equipped with a wiping mechanism that prevents the rate from decreasing and simplifies maintenance, and its practical value is great.
