[0041] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0042] like Figure 1 As shown, this embodiment provides an ozone oxidation system with jet mixing and air distribution, including an ozone supply unit 1, a water inlet unit 2, a primary jet oxidation unit 3, a secondary jet oxidation unit 4, a water outlet pool 5 and an exhaust gas processor 6.

[0043] The ozone supply unit comprises an ozone generator 11, an ozone flowmeter 12 and a pressure control valve 13. The ozone flowmeter 12 is connected to the ozone generator 11 and the jet ozone doser 31 of the primary jet oxidation unit 3 through a pipeline. The pressure control valve 13 is connected to the ozone flowmeter 12 and the jet oxidizer 42 in the secondary jet oxidation unit through a pipeline.

[0044] The water inlet unit 2 includes a water inlet pool 21, a water inlet jet pump 22 and a water inlet pump 23. The water inlet jet pump 22 connects the water inlet pool 21 with the jet ozone doser 31 of the primary jet oxidation unit 3 through a pipeline. The water inlet pump 23 connects the water inlet pool 21 with the water inlet jet mixer 32 of the primary jet oxidation unit 3 through a pipeline.

[0045] The primary jet oxidation unit 3 comprises a jet ozone injector 31 and a primary jet oxidation pool 33 . The primary jet oxidation pool 33 contains a water inlet jet mixer 32 and an ozone jet mixer 34 . The ozone jet mixer 34 is connected to the outlet of the jet ozone injector 31 .

[0046] The secondary jet oxidation unit 4 includes a vacuum induced draft fan 41, a secondary jet oxidation pool 43, a jet oxidizer 42 and a secondary jet oxidation pump 44. The inlet of the vacuum induced draft fan 41 is connected to the upper part of the primary jet oxidation pool 33, and the air inlet and water inlet of the jet oxidizer 42 are respectively connected to the outlet of the vacuum induced draft fan 41 and the outlet of the secondary jet oxidation pump 44. The inlet of the secondary jet oxidation pump 44 is connected to the water outlet pool 6.

[0047] The water inlet jet mixer 32 and the ozone jet mixer 34 are arranged at a certain distance at the bottom of the primary jet oxidation pool 33, and the net distance from the pool bottom is in the range of 0.3-0.8m. The jet ozone doser 31 is arranged at the top of the primary jet oxidation pool 33. The jet oxidizer 42 is arranged at the bottom of the secondary jet oxidation pool 43, and the net distance from the pool bottom is in the range of 0.5-1.2m.

[0048] A primary water inlet 331 and a secondary water inlet 431 are respectively provided at the bottom of the terminal pool bodies of the primary jet oxidation pool 33 and the secondary jet oxidation pool 43 .

[0049] An ozone air retaining wall 432 and a water retaining wall 61 are respectively provided at the rear end of the secondary jet oxidation pool 43 and the front end of the water outlet pool 6.

[0050] The first-stage jet oxidation pool 33 and the second-stage jet oxidation pool 43 are connected to the exhaust gas processor 5 through pipelines.

[0051] The sewage treatment principle or process of the jet air distribution ozone oxidation device provided in this embodiment is as follows: a part of the sewage in the water inlet pool 21 is pumped into the water inlet jet mixer 32 in the primary jet oxidation pool 33 of the primary jet oxidation unit 3 through the water inlet pump 23, and the sewage enters the primary jet oxidation pool 33 evenly through the water inlet jet mixer 32 and is fully mixed with the sewage in the primary jet oxidation pool 33; the remaining part of the sewage in the water inlet pool 21 is pumped into the jet ozone doser 31 through the water inlet jet pump 22, and the sewage flow rate in the jet ozone doser 31 is accelerated to form a negative pressure, and the ozone generated by the ozone supply unit 1 is sucked in and fully mixed with the sewage. The mixed ozone and sewage enter the ozone jet mixer 34, and then enter the primary jet oxidation pool 33 evenly through the ozone jet mixer 34. The ozone in the primary jet oxidation unit 3 is mixed with the sewage in the pool for a secondary time. Through the secondary mixing, most of the ozone reacts with the pollutants in the sewage to oxidize and remove the pollutants. The remaining ozone in the primary jet oxidation unit 3 escapes from the water surface of the primary jet oxidation pool 33, and is extracted by the vacuum induced draft fan 41 of the secondary jet oxidation unit 4 and transported to the jet oxidizer 42 of the secondary jet oxidation unit 4. At the same time, the secondary jet oxidation pump 44 extracts the treated sewage from the outlet pool 6 into the jet oxidizer 42. The sewage flow rate in the jet oxidizer 42 is accelerated to form a negative pressure, and the remaining ozone extracted by the vacuum induced draft fan 41 is sucked in and fully mixed with the sewage in the jet oxidizer 42. The jet liquid dissolved in ozone is further pressurized by the jet oxidizer 42 and then sprayed into the secondary jet oxidation pool 43, thereby completing the oxidation and removal of pollutants in the sewage. In addition, when necessary, the ozone supply amount of the primary jet oxidation unit 3 and the secondary jet oxidation unit 4 can be adjusted by the ozone flowmeter 12 and the pressure control valve 13 in the ozone supply unit 1, so that the secondary jet oxidation unit 4 can simultaneously use the remaining ozone of the primary jet oxidation unit 3 and the ozone generated by the ozone generator 11. The ozone not used by the system enters the exhaust processor 5 through the pipes at the upper parts of the primary jet oxidation pool 33 and the secondary jet oxidation pool 43, and is discharged after being treated.

[0052] During the sewage treatment, the sewage will enter the secondary jet oxidation tank 43 from the primary water outlet 331 at the bottom of the primary jet oxidation tank 33, pass through the air retaining wall 432 in the secondary jet oxidation tank 43 upward, and then pass through the secondary water outlet 431 at the bottom of the secondary jet oxidation tank 43 downward, and finally enter the outlet tank 6. This design allows the sewage to travel a longer distance in the tank and prevents residual ozone from entering the outlet tank 6 with the water flow; at the same time, a retaining wall 61 is designed in the front part of the outlet tank 6 so that the liquid level in the secondary jet oxidation tank 43 is not affected by the liquid level of the outlet tank 6.

[0053] Compared with the prior art, the ozone oxidation device with jet air distribution provided in this embodiment has the following advantages:

[0054] First, the jet ozone doser 31 of the primary jet oxidation tank 33 uses influent water as the jet liquid. The strong mixing of influent water and ozone in the jet ozone doser 31 can make the influent water and ozone react more fully, thereby increasing the ozone utilization efficiency.

[0055] Second, the water jet mixer 32 and the ozone jet mixer 34 in the primary jet oxidation tank 33 can fully mix the ozone and sewage for a second time in the tank, increase the mixing frequency of ozone and pollutants in sewage, and further increase the ozone utilization efficiency and pollutant removal efficiency;

[0056] Third, the unreacted ozone in the primary jet oxidation unit 3 is transported to the jet oxidizer 42 of the secondary jet oxidation unit 4 through the vacuum induced draft fan 41, and then fully mixed with the sewage in the jet oxidizer 42 and the secondary jet oxidation tank 43, so that the residual ozone in the primary jet oxidation unit 3 is fully utilized, further increasing the utilization efficiency of ozone, while reducing the generation of residual ozone, and reducing the energy consumption of the ozone generator 11 and the exhaust gas processor 5;

[0057] Fourth, the ozone flowmeter 12 and the pressure control valve 13 in the ozone supply unit 1 can adjust the ozone supply amount of the primary jet oxidation unit 3 and the secondary jet oxidation unit 4, so that the secondary jet oxidation unit 4 can directly utilize the ozone generated by the ozone generator 11 while utilizing the residual ozone of the primary jet oxidation unit 3, thereby increasing the flexibility of the system.
