example one
As shown in figure 1, the high-efficiency oxidation device comprises a body 1, and further comprises a liquid inlet manifold 2, a liquid discharge manifold 3 and an aeration manifold 4.
The body 1 comprises a shell and a separating device arranged in the shell, wherein the separating device divides an inner cavity of the shell into a first cavity and a second cavity which are communicated through a middle channel.
In the embodiment, the shell is a vertical outer cylinder 1-1, and the separating device is an inner cylinder 1-2 positioned in the outer cylinder 1-1; the upper end of the inner cylinder 1-2 is connected with the outer cylinder 1-1, the middle channel is positioned at the bottom of the outer cylinder 1-1, the first cavity is a columnar inner cavity of the inner cylinder 1-2, and the second cavity is an annular cavity between the inner cylinder 1-2 and the outer cylinder 1-1.
Furthermore, the body 1 also comprises an annular connecting plate 1-5, and the outer wall of the inner cylinder 1-2 is connected with the inner wall of the outer cylinder 1-1 through the connecting plate 1-5 to strengthen the support.
And a liquid outlet of the liquid inlet manifold 2 is arranged at the top end of the first cavity. The liquid outlet of the liquid inlet manifold 2 is provided with a water distributor 8, so that the water inlet is more uniform, and the water surface in the tank body is free of fluctuation and turbulence.
And a liquid inlet of the liquid drainage manifold 3 is arranged on the side wall of the outer cylinder body 1-1 and is positioned at one end, far away from the middle channel, of the second cavity.
The air outlet of the aeration manifold 4 is arranged at the bottom of the first cavity, and an aerator 9 is arranged at the air outlet of the aeration manifold 4.
The aeration manifold 4 is provided with an inverted U-shaped pipe section, or the aeration manifold 4 is provided with a one-way valve or other backflow prevention devices. When the aeration is stopped, the pipeline loses pressure suddenly, and the sewage in the tank can not flow back to the inside of the ozone generating device.
The body 1 is further provided with a tail gas discharge port 6, and the tail gas discharge port 6 is arranged at the top end of the first cavity.
Furthermore, a horizontal partition plate 7 is arranged at the middle-lower position of the first cavity, and the partition plate 7 is positioned between the water distributor 8 and the aerator 9 and is provided with through holes. And a suspended filler 5 is placed in a space between the partition plate 7 and the liquid outlet of the liquid inlet manifold 2. The specific gravity of the suspended filler 5 and water is 1:1, and can be adjusted according to the liquid inlet components. The suspended filler 5 can uniformly cut ozone aeration bubbles, so that the ozone aeration bubbles are more uniform, and the contact between ozone and organic matters in sewage is more sufficient.
The body 1 is also provided with an access hole 1-3 communicated with the first cavity, and the access hole 1-3 is provided with a glass sight glass, so that the reaction effect can be observed conveniently and the access can be carried out conveniently.

In this embodiment, however, the direction of the wastewater in the first chamber flowing to the second chamber is the only direction; in the first embodiment, the sewage can reach the second cavity when moving all around. Therefore, the working efficiency of the present embodiment is lower than that of the first embodiment.
