[0021] Embodiment

[0022] Referring to Figures 1-4 , an embodiment provided by the present utility model: an integrated wastewater treatment device, including a treatment tank 1. A sewage tank 2 is provided inside the treatment tank 1. A water inlet pipe 3 is provided at a position corresponding to the upper end of the sewage tank 2 on the left side of the treatment tank 1. An ozone nano-bubble generating mechanism 4 is provided on the right side of the treatment tank 1. The ozone nano-bubble generating mechanism 4 includes a mixing tank 41. The mixing tank 41 is installed on the treatment tank 1. A mixing chamber 42 is provided at the lower side inside the mixing tank 41. The right end of the mixing chamber 42 is connected to an air inlet pipe 43. A water inlet 44 is provided at the upper end of the mixing chamber 42. A filter 10 is installed on the water inlet pipe 3 to preliminarily filter out impurities in the sewage.

[0023] The lower end of the mixing tank 41 is connected to a liquid outlet pipe 47. The other end of the liquid outlet pipe 47 penetrates through the treatment tank 1 and is connected to the bottom end of the sewage tank 2. Ultrasonic oscillators 45 are installed at corresponding positions on both sides of the inner wall of the mixing chamber 42. A microporous plate 48 is covered at the position of the air inlet pipe 43 on the inner wall of the mixing tank 41. The upper end position of the mixing tank 41 is higher than the upper side of the sewage tank 2. Valves are installed on the air inlet pipe 43 and the liquid outlet pipe 47. The lower end of the water inlet 44 is connected to a water pipe 49. The lower end of the water pipe 49 is connected to a water pump 410. The lower end of the water pump 410 is installed with a water tank 411. Control the water pump 410 to work to pump out the water in the water tank 411, and inject water into the mixing chamber 42 through the water inlet 44. Open the valve on the air inlet pipe 43, and high-pressure ozone gas is input into the air inlet pipe 43. Under the action of the microporous plate 48, the large-molecule ozone bubbles in the water are cut. Under the action of the microporous plate 48, the bubble diameter can be within the required range. Then control the ultrasonic oscillator 45 to work to cut and separate the smaller-molecule ozone bubbles in the water again, forming a large number of micro-nano bubbles, increasing the solubility of ozone, enhancing the oxidation effect and utilization rate of ozone. After the mixing chamber 42 is filled with water, open the valve on the liquid outlet pipe 47, and the water mixed with ozone bubbles enters the sewage tank 2. Ozone undergoes an oxidation-reduction reaction with the pollutants in the wastewater. Ozone can convert the high-molecular organic matter in the sewage into low-molecular substances and convert non-polar substances into polar substances. One end of a water outlet pipe 5 is connected to the lower end of the sewage tank 2. The other end of the water outlet pipe 5 penetrates out of the treatment tank 1. Valves are installed on the water inlet pipe 3 and the water outlet pipe 5. An exhaust pipe 6 is provided at the upper end of the treatment tank 1. A valve is installed on the exhaust pipe 6. A pressure sensor 7 is installed on the treatment tank 1. When ozone oxidizes the wastewater in the sewage tank 2, a colorless, odorless and pollution-free gas will be generated. When a certain pressure value is reached, open the valve on the exhaust pipe 6 to discharge the gas. A support base 8 is installed at the lower end of the treatment tank 1. A glass observation window 9 is provided on the treatment tank 1 to facilitate observing the change in the color of the wastewater during the oxidation reaction.

[0024] Working principle: First, open the valve on the water inlet pipe 3 to discharge the wastewater into the sewage tank 2. Then, open the valve on the air inlet pipe 43, control the water pump 410 to work to pump out the water in the water tank 411, and inject water into the mixing chamber 42 from the water inlet 44. Open the valve on the air inlet pipe 43, and the high-pressure ozone gas is input into the air inlet pipe 43 and enters the water to form large bubbles. Under the action of the microporous plate 48, the large bubbles of ozone in the water are cut. Under the action of the microporous plate 48, the bubble diameter can be within the required range. Then, control the ultrasonic oscillator 45 to work to cut and separate the bubbles of smaller molecular ozone in the water again to form a large number of micro-nano bubbles, increasing the solubility of ozone, enhancing the oxidation effect and utilization rate of ozone. After the water in the mixing chamber 42 is filled, open the valve on the liquid outlet pipe 47, and the water mixed with ozone bubbles enters the sewage tank 2. Ozone undergoes an oxidation-reduction reaction with the pollutants in the wastewater. Ozone can convert the high-molecular organic matter in the sewage into low-molecular substances and convert non-polar substances into polar substances. Observe the change in color in the sewage tank 2 and the change in pressure in the treatment tank 1. When ozone oxidizes the wastewater, it will produce a colorless, odorless and pollution-free gas and no precipitate, which is green and environmentally friendly. Finally, open the valves on the exhaust pipe 6 and the water outlet pipe 5 to discharge the purified water.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
