Owing to existing part bubble has passed mobile plate 4, the bubble that passes mobile plate 4 can be more evenly tiled on the lower surface of grid plate 5, should be that the aperture of grid plate 5 is less, bubble in water Due to the surface tension effect, it is difficult to break directly, but some air bubbles stay under the moving plate 4 and drive it up, and the moving plate 4 approaches the grid plate 5, and the bubbles trapped between the...

Abstract

The invention discloses an aerobic zone reaction tank in sewage treatment. The aerobic zone reaction tank in sewage treatment comprises a reaction tank, wherein a conveying pipe is arranged on the bottom part of the reaction tank; multiple output ends communicate onto the conveying pipe; a grid plate and a movable plate are arranged in the reaction tank; the grid plate is arranged above the movable plate; two ends of the grid plate are fixedly connected with the inner wall of the reaction tank; multiple springs are connected between the grid plate and the movable plate; multiple limiting shafts are fixedly connected below the grid plate and penetrate through the movable plate; suspension boxes are symmetrically arranged under the movable plate; and balance weight liquid is filled in the suspension boxes. According to the aerobic zone reaction tank in sewage treatment provided by the invention, a floating force in the air ascending process input into the reaction tank is utilized for pushing the movable plate, the movable plate moves to the grid plate, and large-volume bubbles stayed in the movable plate is extruded in the movement process and are then extruded into small bubbles, so that a bubble crushing effect is achieved, and the contact area of the bubbles and nitrifying bacteria in sewage is increased.

Example Embodiment

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inside", " The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, so as to The specific orientation configuration and operation are therefore not to be construed as limitations of the present invention.

[0018] refer to Figure 1-2 , an aerobic zone reaction tank in sewage treatment, comprising a reaction tank 1, characterized in that, the bottom of the reaction tank 1 is provided with a conveying pipe 2, the conveying pipe 2 is connected with a plurality of output ends 3, and the reaction tank 1 is provided with The grid plate 5 and the mobile plate 4, the grid plate 5 is arranged above the mobile plate 4, the two ends of the grid plate 5 are fixedly connected with the inner wall of the reaction tank 1, and there are many connections between the grid plate 5 and the mobile plate 4. There are springs 7 , and a plurality of limit shafts 6 are fixedly connected below the grid plate 5 , and the plurality of limit shafts 6 pass through the moving plate 4 .

[0019] A suspension box 8 is symmetrically installed below the mobile plate 4, and the suspension box 8 is filled with a counterweight liquid. The suspension box 8 is used to balance the mobile plate 4 so that it is suspended in the water. The mobile plate 4 is provided with a corresponding limit shaft 6. The limit shaft 6 passes through the socket, a plurality of balls 9 are installed on the inner wall of the socket, and the plurality of balls 9 can reduce frictional force, and the moving plate 4 is provided with a plurality of large apertures.

[0020] In the present invention, when the user uses the device, when the sewage is transported to the aerobic zone, the sewage will react in the reaction tank 1, and the nitrifying bacteria in the reaction tank 1 will react with impurities such as nitrogen in the sewage , which is decomposed into nitrogen-containing ions and precipitated. During the reaction process, the bacteria need to transport air to the interior through the conveying pipe 2 for the use of nitrifying bacteria. After going out, the buoyancy from bottom to top floats up;

[0021] When the air is rising, the pressure at the bottom of the pool is high, and it gradually decreases during the rising process. When the air is at the bottom of the pool, the air is relatively small bubbles. The contact area becomes smaller. When the bubble rises, it first encounters the moving plate 4. The moving plate 4 is provided with a larger aperture. The bubble will pass through the large aperture, and it will also encounter a solid structure that is difficult to rise. The moving plate 4 has an upward buoyancy effect. In the initial state, the moving plate 4 is in a balanced state in the sewage. The suspension box 8 fixedly connected with the moving plate 4 provides buoyancy, and the spring 7 provides an upward pulling force. When the buoyancy of the bubble is increased, it will inevitably move upward;

[0022] Since some air bubbles have passed through the moving plate 4, the air bubbles passing through the moving plate 4 will be more evenly spread on the lower surface of the grid plate 5. It should be because the aperture of the grid plate 5 is small, and the air bubbles in the water have surface tension. It is difficult to break directly, and some air bubbles stay under the moving plate 4 and drive it to rise, the moving plate 4 approaches the grid plate 5, and the air bubbles trapped between the grid plate 5 and the moving plate 4 will be squeezed into The small air bubbles are removed from the various gaps of the grid plate 5, so that the large air bubbles are divided into small air bubbles, which effectively increases the contact area with the nitrifying bacteria in the sewage, improves the efficiency of the ammoniation and nitrification process, and all the air is squeezed. After being pressed out, the moving plate 4 is reset under the elastic force of the spring 7 .
