Aeration oxygenation device for industrial sewage treatment

Abstract

The invention discloses an aeration oxygenation device for industrial sewage treatment, and relates to the field of aeration oxygenation. The aeration oxygenation device comprises a box body, wherein the top side of the box body is fixedly provided with a baffle plate, one side of the baffle plate is fixedly provided with a motor, and the output end of the motor is fixedly provided with a rotating shaft through a coupling. According to the invention, an air extracting pump is started to enable oxygen in an oxygen tank to enter a spray head through a guide pipe and a hose, the spray head sprays the oxygen into sewage, a motor rotates to drive a rotating shaft and a rotating disc to rotate, the rotating disc rotates to drive a cylindrical block to rotate, the cylindrical block rotates to drive a fixing rod to rotate, and the fixing rod rotates to drive the spray head to swing back and forth on a fixing plate, so that oxygen can be uniformly sprayed into the sewage, and the contact area of the oxygen and the sewage is increased. Meanwhile, harmful gas in the sewage is discharged from a gas outlet pipe after being filtered by an activated carbon layer, then the harmful gas in the sewage can be adsorbed, and the harm to a human body is avoided.

Description

technical field [0001] The invention relates to the field of cargo transportation, in particular to an aeration and oxygenation device for industrial sewage treatment. Background technique [0002] With the development of environmental protection, sewage biochemical treatment has been paid more and more attention, and the treatment methods are also increasing. In addition to activated sludge method and biofilm method, biological contact oxidation method has also been widely used in urban sewage and industrial wastewater in recent years. During the treatment, especially for some industrial wastewater, in order to avoid the expansion of activated sludge and facilitate the operation and management of the treatment plant, the biological contact oxidation method is adopted. However, whether it is activated sludge method or contact oxidation method, aeration and oxygenation are indispensable and important components. [0003] The oxygen charged by the existing aeration and oxygen...

AI Technical Summary

Problems solved by technology

[0003] The oxygen charged by the existing aeration and oxygenation device cannot be in contact with industrial sewage in large quantities, and has not fully exerted its effective effect. Moreover, during aeration and oxygenation, harmful gases in industrial sewage will emerge, and the existing aeration The gas oxygenation device does not filter the gas, and directly discharges harmful gas into the environment, causing harm to the human body. Therefore, we propose an aeration and oxygenation device for industrial sewage treatment
