A Piece of Municipal Automatic Sewage Treatment Equipment
Technical Field The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a piece of aeration equipment, specifically a piece of municipal automatic sewage treatment equipment.
Background Technology Aeration is required in sewage treatment. Aeration is a process of forcibly transferring oxygen in the air to the liquid, and its purpose is to obtain sufficient dissolved oxygen. Aeration can also prevent the sedimentation of the suspended body in the pool, and strengthen the contact of organic matter in the pool with microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool have sufficient dissolved oxygen. The oxygen in the gas is dissolved in the water to generate dissolved oxygen, and the dissolved oxygen promotes microorganisms to oxidize the organic matter in the sewage to achieve the degradation of the organic matter in the sewage. In the sewage treatment process, in order to obtain sufficient dissolved oxygen in the water body, the main aeration methods used are blast aeration and mechanical aeration. Blast aeration is to set up an air pump and a high-pressure air outlet at the bottom of the aeration tank to diffuse air bubbles into the sewage liquid. Mechanical aeration is the use of mechanical equipment to continuously update the liquid surface and sewage to promote the transfer of air to the liquid at the interface. In order to improve the efficiency of aeration, in the prior art, most of the aeration tanks are installed with stirring devices to agitate the sewage, at the same time, the sewage is blown and aerated. The gas will be more fully contacted with the agitation of the sewage, so as to prolong the time for the dissolved oxygen to promote the degradation of organic matter by microorganisms. There is also a combination of blast aeration and stirring device, and the recoil force of the blast is used to drive the aeration and stirring device, so as to achieve the purpose of improving aeration efficiency and saving energy. However, only relying on the recoil force of the blast to push the stirring device is very limited, it cannot achieve a good mechanical aeration and stirring effect, and it is only suitable for small aeration tanks, not suitable for use in aeration tanks.

ueseriptions
When the present invention is used, the equipment is placed on the sewage surface of the aeration tank, and the suspension box1 has sufficient drainage volume to support the equipment
to stably float on the sewage surface. The arrangement of the water seal 4 prevents sewage from entering the inner cavity of the suspension box 1 and protects the air pump 11, the water pump 12 and the rotating support structure. The Seal plate 9 enables the suspension box 1 to have a
stable drainage volume to ensure safety. Both the air pump 11 and the water pump 12 are driven by a waterproof motor, which makes the equipment have strong environmental resistance, long service life, and safety and stability. Start the air pump 11 and the water pump 12. When the air pump 11 is working, the outside
air enters the main air pipe 13 from the upper air inlet of the main air pipe 13, passes through the bronchus 14, enters the lower cavity of the rotating drum 2 from the air duct 15 through the air pump 11, and exits from the exhaust port 17 of the lower swing pipe 16. The outside air enters
the sewage and transfers the oxygen in the air to the sewage to form a blast aeration. At the same time, the recoil force of the lower swing pipe 16 makes the lower swing pipe 16 and the rotating drum 2 rotate, and the lower swing pipe 16 has a stirring effect on the sewage. Because thelower swing pipe 16 is a flat and inclined structure, it can promote the vertical and horizontal agitating
movement of the sewage, at the same time, the recoil force of the lower swing pipe 16 makes the lower swing pipe 16 and the drum the rotating drum 2 rotate, and the lower swing pipe 16 has a stirring effect on the sewage. Since the lower swing pipe 16 is a flat and inclined structure, it can promote the vertical and horizontal stirring movement of the sewage to renew the sewage on the
surface of the aeration tank. When the water pump 12 is working, the external sewage enters the main water pipe 18 from the water inlet at the lower end of the main water pipe 18, passes through the branch pipe 19, enters the upper cavity of the rotating drum 2 from the water guiding
pipe 20 through the water pump 12, and is discharged from the drain outlet 22 of the upper swing pipe 21 .The sewage sprayed by the upper swing pipe 21 forms a fountain above the water surface, so that the sewage is evenly dispersed in the air, forming fountain aeration, and fully contacting the dissolved oxygen with the air, the aeration effect is comprehensive and efficient.
At the same time, the sewage is discharged from the upper swing pipe 21, and the recoil force pushes the upper swing pipe 21 and the rotating drum 2 to rotate, which provides stronger power for the rotation of the rotating drum 2 and the lower swing pipe 16, overcomes the resistance of
the lower swing pipe 16 in the water, and strengthens the lower swing pipe 16. The stirring effect in the sewage strengthens the effect of mechanical aeration.
