Problems solved by technology

[0002] In the process of sewage treatment, air is forced into the sewage for aeration, so that the sewage in the pool is contacted with air to oxygenate, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent the suspended objects in the pool from sinking, and strengthen the pool. The contact of organic matter with microorganisms and dissolved oxygen oxidizes and decomposes organic matter in sewage; in winter or in northern regions due to the colder climate, the reaction rate in the sewage pool will decrease. It is not eas

Abstract

The invention discloses an oxygenation and aeration device for sewage purification. The oxygenation and aeration device comprises a sewage aeration tank; a fixed cross beam is arranged above the sewage aeration tank; the lower side of the fixed cross beam is fixedly connected with a cylinder support; the oxygenation and aeration device further comprises a vertical cylinder body; the outer wall ofthe vertical cylinder is fixedly supported and connected to the lower end of the cylinder support; a gas supply channel is coaxially arranged in the vertical cylinder body; a horizontal air supply platform is fixedly connected to the upper end of the vertical cylinder body; and the air supply platform is provided with a centrifugal booster fan, an air heater and an air inlet shell. The oxygenationand aeration device is simple in structure, and is used for continuously aerating hot air into sewage, so that aeration and oxygenation are carried out on the sewage, a certain heating effect is achieved, and reaction activity of the sewage is maintained.

Description

technical field [0001] The invention belongs to the field of sewage purification. Background technique [0002] In the process of sewage treatment, air is forced into the sewage for aeration, so that the sewage in the pool is contacted with air to oxygenate, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent the suspended objects in the pool from sinking, and strengthen the pool. The contact of organic matter with microorganisms and dissolved oxygen oxidizes and decomposes organic matter in sewage; in winter or in northern regions due to the colder climate, the reaction rate in the sewage pool will decrease. It is not easy to directly use boiler or electric heating to force heating Controlling the temperature can easily kill the microorganisms in the sewage, which will cause the disadvantage of a decrease in the reaction; [0003] In addition, in the existing process of oxygen-increasing aeration, the water in the sewage tank is...
