Description

Corundum aeration equipment for sewage treatment

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a corundum aeration device for sewage treatment.

Background

Aeration is the process of forcing the oxygen in the air to be transferred into the liquid, with the aim of obtaining sufficient dissolved oxygen. Aeration is mainly applied to the aquaculture field and the sewage treatment field, and in the sewage treatment process, certain method and equipment are used for forcibly introducing air into sewage to ensure that the sewage in the tank is in contact with the air to be oxygenated, and stirring liquid to accelerate the transfer of oxygen in the air into the liquid, so that suspended objects in the tank are prevented from sinking, the contact of organic matters in the tank with microorganisms and dissolved oxygen is enhanced, and the organic matters in the sewage are subjected to oxidative decomposition. The sewage treatment mainly uses a corundum aerator, and the corundum aerator uses brown corundum as a main raw material and is a plate-shaped or bell-shaped high-efficiency energy-saving blast oxygen-charging aeration device which is formed by pressing and sintered at high temperature.

The existing corundum aerator is usually arranged at the bottom of a sewage tank and is connected with an external air pipe, and the sewage is oxygenated and stirred by generating bubbles through micropores of a corundum cover, but the operation still has the following defects: the corundum cover is small in fan-shaped diffusion range upwards at the bottom of the sewage pool, and the service range is 5M²Left and right, and because the corundum cover can only oxygenate upwards, can't oxygenate and stir to aerator periphery and downside for sewage in the bottom of the effluent water sump can subside. Therefore, it is important to design a corundum aerator capable of expanding the oxygenation stirring range, and in view of the above, a corundum aerator for sewage treatment is provided.
