Problems solved by technology

The blown air forms bubbles in the water and floats to the water surface. As the blowing continues, the formed bubbles are successively combined into large bubbles. The large bubbles are large in size and receive a large buoyancy force, and they will quickly float to the water surface, causing the bubbles to float in the water body. The residence time in the pool is short, and the microorganisms in the water body are also difficult to absorb the oxygen in the air bubbles. Therefore, although the aeration is kept in the pool, the actual effect is very general.

Embodiment 1

[0023] refer to Figure 1-3 , a high-efficiency aeration and dissolved oxygen type microbial sewage treatment pond, comprising a pond body 1, a plurality of outlet pipes 2 are installed at the inner bottom of the pond body 1, and the upper end of the outlet pipe 2 is fixedly connected with an exhaust pipe communicating with the inside of the outlet pipe 2 3. It should be noted that the air outlet ends of the air outlet pipe 2 and the exhaust pipe 3 are both closed.

[0024] The side wall of the exhaust pipe 3 is provided with a plurality of exhaust holes 31, and the inner sealing and rotation of the exhaust pipe 3 is connected with the arc block 5, and the driving device for driving the arc block 5 to rotate is installed in the exhaust pipe 3.

[0025] It should be noted that a plurality of exhaust holes 31 are equally spaced along the outer wall of the exhaust pipe 3, and the central angle of the arc-shaped block 5 is slightly greater than twice the angle between two adjacent...

Embodiment 2

[0032] refer to Figure 4-5 , different from Embodiment 1, one of the blades of the water wheel 6 is made of magnetic material, and the other blades of the water wheel 6 are made of non-magnetic materials, and the upper end of the air outlet pipe 2 is fixedly connected with a plurality of iron Spring 7, is coated with antirust coating on the spring 7.

[0033] And a plurality of said springs 7 are equidistantly distributed around the exhaust pipe 3, the position and number of the springs 7 are the same as the exhaust holes 31, and the side wall of the air outlet pipe 2 is provided with a plurality of small through holes 21.

[0034] Such as Figure 5 As shown, when the water wheel 6 in this implementation is rotating, the magnetic blades on the water wheel 6 will constantly pass through the iron springs 7 around the exhaust pipe 3. Whenever the magnetic blades are close to the springs 7, the springs 7 can be attracted to stretch upwards. Long, after the magnetic blade leaves...

Abstract

The invention discloses an efficient aeration oxygen-dissolving type microbial sewage treatment tank. The sewage treatment tank comprises a tank body; a plurality of air outlet pipes are installed atthe bottom in the tank body; the upper ends of the air outlet pipes are fixedly connected with exhaust pipes communicated with the interiors of the air outlet pipes; a plurality of exhaust holes are formed in the side walls of the exhaust pipes; arc-shaped blocks are rotatably connected into the exhaust pipes in a sealed mode; and driving devices for driving the arc-shaped blocks to rotate are installed in the exhaust pipes. With the arrangement of the driving devices, the arc-shaped blocks are pushed to rotate in the air blowing process; therefore, the exhausted air can be exhausted from theexhaust holes one by one, and aeration is carried out at intervals; and meanwhile, the aeration position is continuously changed, so that bubble fusion can be avoided, the bubble volume is reduced, the retention time of bubbles in water is prolonged, microorganisms in water can have enough time to absorb oxygen in the air, the activity of microorganisms in the tank is promoted, and the sewage treatment efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of equipment related to sewage treatment, in particular to a high-efficiency aeration and oxygen-dissolving microbial sewage treatment pool. Background technique [0002] In the process of sewage treatment, in order to degrade the pollutants in the sewage, most of the sewage is injected into the sewage tank containing a large number of microorganisms for treatment. [0003] In order to improve the activity of microorganisms in the sewage pool, in the prior art, air is introduced into the pool through blowers, aeration pipes and other equipment to increase the oxygen content in the water body. The blown air forms bubbles in the water and floats to the water surface. As the blowing continues, the formed bubbles are successively combined into large bubbles. The large bubbles are large in size and receive a large buoyancy force, and they will quickly float to the water surface, causing the bubbles to float in th...
