被処理原水は分断。Since the first invention has the above-mentioned configuration, air or oxygen from an oxygen cylinder is injected from the air or oxygen intake port 4 into the quartz glass tube 2 at a pressure higher than the water pressure around the outer periphery of the quartz glass tube 2. When the quartz glass tube 2 is sucked in, ultraviolet rays with wavelengths of mainly 184.9 mμ and 253.7771 μm are emitted.
Oxygen or oxygen gas in the air is decomposed by ultraviolet rays of 9 mμ to generate ozone gas. This ozone, air mixture or ozone, oxygen mixture gas is the ozone, air or ozone, oxygen mixture opened in the quartz glass tube 2. The gas is discharged from one end 13 of the gas extraction tube 14 through the extraction tube 14 onto the central axis 02 02 of the swirling flow forming section 8 of the fine bubble generation tube 10 . The raw water to be treated passes through the raw water supply pipe 12 to one end of the fine bubble generating tube 10, and the raw water to be treated is pressurized by a pump (not shown). □ forces a swirling flow, creating a negative pressure cavity near the central axis Or If oxygen from an oxygen cylinder (not shown) is taken in instead of air, the mixed gas of ozone and oxygen is sucked out, and the protrusions 9. The raw water to be treated is divided.

存在により一層増加される。Although it is sheared and well stirred, the ozone, air, or ozone-oxygen mixture gas sucked onto the central axis 02 of the swirling flow forming section 8 is similarly divided and sheared as it is sucked into the swirling flow. , disperses in water to form extremely fine bubbles (approximately 0.5 mm or less), increasing the contact area of ozone in the water, thus increasing the solubility of ozone, and fine bubbles take a long time to rise to the water surface. Therefore, the residence time of ozone gas in water increases, and the amount of ozone dissolved in water increases. In this way, ozone and air or oxygen gas are well mixed, and the stirred water then rises around the outer periphery of the quartz glass tube 2 and becomes 253.7 mμ.
Ultraviolet rays with a wavelength of 100 to 1000 ml kill bacteria in water and decompose organic matter, but this decomposition of organic matter is further increased by the presence of ozone gas.

昇する。In the second invention, since the diameter of the tube 9 in the fine bubble generating tube 10 is smaller than the tube diameter at the end 7, the raw water to be treated increases the flow rate through the limb tube 9, and the fine bubble generating tube 10 other end 1
1 are connected in the direction of the dividing line Os near the inner wall of the cylindrical body 1. Therefore, the water flow swirls along the inner wall of the cylindrical body 1 and rises spirally. Ozone, air, or a mixture of ozone and oxygen, which has become extremely fine bubbles, rises extremely slowly while swirling inside the cylinder 1, so it stays in the water for an extremely long time. Since the amount of dissolved ozone increases significantly, the wastewater treatment capacity increases.

The solubility of ozone in water increases as the water temperature decreases, as shown in Table 2. The effect of equipping it is great.

できる。This invention has a configuration like an upward slope, and has a 184.9
mμ, 184.9 of ultraviolet light with a wavelength of 253.7 mμ
The solubility of ozone can be increased by generating ozone on the mμ side to create a mixed gas of ozone and air or a mixed gas of ozone and oxygen, making the mixed gas into finer bubbles, and lengthening the residence time in water. Wavelength 253.7 mμ
The sterilization of the raw water to be treated and the decomposition of organic matter by side ultraviolet rays are made more powerful due to the presence of dissolved ozone with high solubility, and ozone, air mixtures or ozone,
The fine bubbles of the oxygen gas mixture slow down the rise in the cylinder 1, thereby further increasing the ozone solubility, and by cooling the fine bubble generating tube 10, the ozone solubility is further increased. It is possible to provide a wastewater treatment device that contributes extremely effectively to water pollution removal. Note that the raw water to be treated may be used for drinking water, and the raw water to be treated may be used for drinking water, or the raw water discharged from the treated raw water outlet 16 of the cylindrical body 1 may be The treated raw water is returned to the raw water supply pipe 12 via a tank or the like and is circulated to completely purify the water quality.
