Problems solved by technology
[0002] Sewage oxygenation and aeration is one of the important processes in sewage purification. In the existing process of oxygenation and aeration, the water in the sewage pool is often static, with low fluidity, and the aeration process is not fully diffused. The oxygen concentration in the area where the aeration is relatively concentrated is relatively high, and it is difficult to dissolve the oxygen again, causing the oxygen in the air bubbles to not fully dissolve in the sewage, and to escape to the outside again, resulting in the problem of low aeration efficiency

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] as attached Figures 1 to 6 The shown aeration device for sewage purification includes a sewage aeration tank 23, and an aeration mechanism 21 is provided below the sewage liquid level 25 in the sewage aeration tank 23, and the aeration mechanism 21 can be The bottom of the sewage liquid surface 25 is periodically floating and sinking.
[0025] The aeration mechanism 21 includes an upper disc 1 and a lower disc 01 arranged at an upper and lower interval, and the upper disc 1 and the lower disc 01 are arranged coaxially; between the upper disc 1 and the lower disc 01 Also includes a vertical central column 7, the upper end of the central column 7 is coaxially connected to the upper disc 1, and the lower end of the central column 7 is coaxially connected to the lower disc 01;
[0026] Between the upper disc 1 and the lower disc 01 are also arranged a number of v...

The invention discloses an aeration device for sewage purification, comprising a sewage aeration tank, wherein an aeration mechanism is arranged below the sewage liquid surface in the sewage aerationtank, and the aeration mechanism can make periodic floating and sinking movements below the sewage liquid surface. The structure of the aeration device of the invention is simple, and aeration is moreuniform; the aeration mechanism below the sewage liquid surface still makes periodic floating and sinking movements in the process of continuously aerating the sewage through an aeration port, thus,horizontal swinging blades make periodic vertical swing movements in the sewage, and further the sewage in the sewage aeration tank continuously undulates, so that aerated water around the aeration mechanism is rapidly diffused, oxygen in bubbles is more evenly dissolved in the entire sewage aeration tank, and also precipitation is effectively prevented.
Description
technical field [0001] The invention belongs to the field of sewage purification. Background technique [0002] Oxygenation and aeration of sewage is one of the important processes in sewage purification. In the existing oxygenation and aeration process, the water in the sewage tank is often static, with low fluidity, and the aeration process is not fully diffused. The concentration of oxygen in the area where the aeration is concentrated is relatively large, and it is difficult to dissolve the oxygen again, so that the oxygen in the bubbles is not fully dissolved in the sewage, and escapes to the outside again, resulting in the problem of low aeration efficiency. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an aeration device and a method for sewage purification with higher aeration efficiency. [0004] Technical solution: In order to achieve the above purpose, an aerati...
