[0039] Working principle: Through the cooperation of the right-angled plate 30 and the sling 21 with an external crane, the two tank bodies 1 are respectively placed on the two connecting frames 4, and the fixing rod 2 at the bottom of the tank body 1 is aligned with the fixing cylinder 5. At this time, hold the sliding sleeve 6 and apply a downward pulling force to stretch the strong spring 12, so that the strong spring 12 can store elastic potential energy, and then give the sliding sleeve 6 a force in the opposite direction to reset. After pulling until the semi-circular opening 9 is horizontal with the sliding ball 7, the sliding sleeve 6 can be fixed. Then, push the fixing rod 2 into the inside of the fixing cylinder 5, and the fixing cylinder 5 will respectively push the two fixing columns 8 to slide away from each other, so that the other two fixing columns 8 will be engaged inside the semi-circular opening 9. As the fixing rod 2 slides and reaches the bottom, release the pulling force on the sliding sleeve 6, so that the strong spring 12 can push the sliding sleeve 6 to reset. As the sliding sleeve 6 resets and slides, it pushes the other two fixing columns 8 to slide, and uses the sliding ball 7 as a transmission object to push two of the fixing columns 8 into the inside of the fixing rod 2 for engagement to complete the rapid installation of the fixing rod 2, thereby improving the installation efficiency;

[0040] Then place the whole device in the sewage pool. Then the sewage flows from left to right, and at the same time, biogas will make the sewage move upward, enter the interior of the tank body 1 through the water inlet at the bottom of the tank body 1. At this time, drive the motor 24 to drive the rotating shaft 25 to rotate, thereby driving the rotating cylinder 26 to rotate, and then driving the rotating blades 27 to rotate, so that the external sewage can quickly flow through from the bottom to the top of the tank body 1, cooperate with the biogas, and then accelerate the water flow rate. At the same time, the rotating blades 27 will also drive the stirring column 28 to rotate, so that the gas, liquid muddy water mixture, and solid filler in the sewage in the tank body 1 are fully and evenly mixed without dead angles. The packing box 20 and the packing plate 19 in the tank body 1 are filled with composite microbial packing and carrier or catalytic packing. On the one hand, the composite microbial packing contains a small amount of deodorizing microorganisms, which plays an inoculation role. On the other hand, it catalyzes and stimulates the deodorizing microbial flora; the carrier or catalytic packing serves as a microbial carrier, dissolves effective components and elements to promote the growth and enrichment of microorganisms and malodorous substances, and at the same time stimulates the life activities of microorganisms and increases the activity of enzymes required in the biological reaction. The slow-release property of the packing enables the deodorization tank system to continuously play a role underwater, maintaining the stability of the deodorizing microbial system, thereby decomposing and removing the malodorous substances in the sewage. The treated water is discharged from the water outlet 22 at the center of the top of the tank body 1. When the deodorization device needs to be lifted and repaired, the right-angle plate 30 outside the top of the tank body 1 can ensure the lifting of the deodorization tank during the operation with water. Lock the stainless-steel sling to the edge of the biological pond with wire buckles for lifting use. The support frame 3 is made of stainless steel, providing stable support for the deodorization tank, preventing the deodorization tank from colliding with the aeration device directly below and causing damage, and also facilitating the later maintenance of the aeration device.

[0041] 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, for those skilled in the art, they can still modify the technical solutions recorded 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.
