The invention discloses an aeration device for municipal sewage treatment, which comprises a pool body, a fixed frame, an aeration plate, an aeration head, a water inlet pipe and a drain pipe. Rotating shaft, the rotating shaft is covered with a drum, the surface of the drum is distributed with a number of main aeration plates, the bottom of the pool is equipped with a water pump, the bottom of the drum is equipped with a stirring shaft, a number of stirring rods are distributed on the stirring shaft, and the bottom of the pool is installed There is an aeration pan, and an air pipe is installed at the left end of the aeration pan. In the process of aerating the sewage, the present invention uses the aeration pan to aerate the bottom sewage; uses the main aeration plate and the auxiliary aeration plate to aerate The surface sewage is raised to make the sewage fully contact with the air, and the surface sewage is aerated. By setting the auxiliary aeration plate, the contact area between the sewage and the air is increased, and the aeration efficiency is improved. The stirring rod is used to stir the bottom sewage to make the sewage and The air bubbles are mixed more evenly, which further improves the aeration efficiency.
Description
technical field [0001] The invention relates to sewage treatment equipment, in particular to an aeration device for municipal sewage treatment. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs. Contents of the invention [0003] The purpos...
