[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present utility model provides a sewage treatment device for ecological environment governance with an aeration mechanism, as Figures 1-4 shown, which includes a treatment tank 1. A water inlet pipe 2 is installed below the left side of the treatment tank 1, a water outlet pipe 3 is installed above the left side of the treatment tank 1, a sewage discharge pipe 4 is installed below the right side of the treatment tank 1, a feeding pipe 5 is installed on the top of the treatment tank 1, a filter screen 6 is installed on the inner side wall of the treatment tank 1, the connection port of the water outlet pipe 3 is located above the filter screen 6, one end of the water outlet pipe 3 away from the treatment tank 1 is installed in the water area, a fixing ring 7 is installed outside the pipe orifice of the water outlet pipe 3, a fixing frame 8 is installed below the fixing ring 7, a support 9 is installed on the upper side of the fixing ring 7, and a water baffle 10 is installed on the top of the support 9. When the device is in use, water is pumped from the water inlet pipe 2 into the treatment tank 1. When the treatment tank 1 is full of water, it will be discharged from the water outlet pipe 3, while the sewage will penetrate upward from below the filter screen 6 for filtration. At the same time, the feeding pipe 5 adds a purifying agent into the interior of the treatment tank 1 to decompose and purify the sewage. The purified water flows back into the water area through the water outlet pipe 3 again. The device filters the sewage by the way of penetrating from bottom to top, and the filtered sundries are concentrated at the bottom of the treatment tank 1 under the action of gravity, which can effectively avoid the problem that the surface of the filter screen 6 is blocked by the accumulated sundries during long-term sewage filtration. By setting the water outlet pipe 3 to spray the treated water into the water area, the aeration treatment of the sewage is realized. By setting the water baffle 10, the water sprayed out of the water outlet pipe 3 can be dispersed in a parabola, increasing the contact time with the air, thereby improving the aeration effect.

[0021] The water baffle 10 is set in an inverted conical shape and is located directly above the nozzle of the water outlet pipe 3. By setting the water baffle 10, when the water in the water outlet pipe 3 impacts the water baffle 10, it will be scattered in a parabolic shape, thereby improving the aeration effect of the device.

[0022] There are four groups of water outlet pipes 3, and the four groups of water outlet pipes 3 are distributed on the outer wall of the treatment tank 1 in a circular array. The inner diameter of the pipe wall of the water outlet pipe 3 is smaller than the inner diameter of the pipe wall of the water inlet pipe 2. By setting the four groups of water outlet pipes 3, the treated water can be scattered separately in the water area, and the water hitting the water surface will also cause air to enter underwater, thereby further improving the aeration effect.

[0023] A fixed disk 11 is installed on the inner side wall of the treatment tank 1, and a motor 12 is installed on the top of the treatment tank 1. A connecting shaft 13 is installed at the end of the output shaft of the motor 12. The connecting shaft 13 is located inside the treatment tank 1. The bottom of the connecting shaft 13 is connected to a turntable 14. The turntable 14 and the surface of the fixed disk 11 are provided with corresponding through slots 15. The turntable 14 and the fixed disk 11 are closely attached to each other. A solenoid valve 16 is installed between the sewage discharge pipe 4 and the treatment tank 1. By setting the fixed disk 11 and the turntable 14, when the sundries at the bottom of the treatment tank 1 are full, the motor 12 can be started at this time. The motor 12 drives the turntable 14 to rotate, so that the notches on the surfaces of the turntable 14 and the fixed disk 11 are misaligned with each other. At this time, the upper and lower parts of the treatment tank 1 can be separated, and the solenoid valve 16 is opened at the same time. At this time, the water entering from the water inlet pipe 2 will flush the sundries in the treatment tank 1 out of the sewage discharge pipe 4, thereby realizing the cleaning of the treatment tank 1.

[0024] Two scraping plates 17 are installed on the upper surface of the turntable 14, and the scraping plates 17 are attached to the lower surface of the filter screen 6. By setting the scraping plates 17, when the turntable 14 rotates, it will drive the scraping plates 17 to scrape the lower surface of the filter screen 6, thereby scraping off the smaller impurities adhering to the surface of the filter screen 6.

[0025] The output pressure of the feeding pipe 5 is greater than the internal water pressure of the treatment tank 1. A valve is installed at the connection between the feeding pipe 5 and the treatment tank 1. By installing a valve at the feeding pipe 5, timed feeding can be carried out according to the actual situation of the water area.
