On the other hand, the air is sucked into the air-collecting chamber through the air intake pipe, and the air entering the air-collecting chamber is broken by the shock wave, the porous crushing plate and the small holes in the aeration chamber wall, and the broken air enters the aeration chamber from all angles of the aeration chamber wall. The air chamber is dissolved in water, and finally the water body mixed with sufficient oxygen is jetted out through the guide tube at the front end of the aeration chamber under the pushing action of the impeller, and fully mixed with the pool water. This invention is also a device placed in the aeration tank. The function area of the porous broken plate is the inner wall, the aeration area is limited, and a certain buffer time is required according to the overall volume of the aeration tank, the flexibility is low, and the device Half of it is underwater and not easy to repair. Compared with this, the present invention directly connects the device to the sewage treatment system without borrowing the aeration tank, the equipment is flexible and easy to maintain, and the worm structure inside the worm barrel can greatly increase the aeration area and improve the aeration efficiency.
