Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a contact oxidation tank for treating dairy wastewater. Background Art

[0002] Contact oxidation tanks work by mixing microorganisms with wastewater. Through aeration and agitation, the microorganisms come into contact with organic matter in the wastewater, thereby degrading the organic matter. In this process, the microorganisms consume oxygen and organic matter, generating energy that fuels their growth and reproduction. Over time, the organic matter in the wastewater is gradually degraded, and the water quality is purified.

[0003] Chinese utility model patent CN220723855U discloses a device for reducing methane emissions from wastewater from dairy farms, comprising a body, one side of which is penetrated by a fixing bolt, one end of which is movably connected to a filter basket; the device for reducing methane emissions from wastewater from dairy farms is provided with an oxidation bin, an air pump, an air supply pipe, a sedimentation bin, a feeding port, an air vent, a drainage pipe and a burner. After the wastewater discharged from the dairy farm is filtered in the previous process, the ventilation pipe discharges the methane and other waste gases generated inside the body into the burner, and then the burner switch is turned on, the burner is burned and the waste gas is discharged after coming out of the burner, thereby reducing greenhouse gas and malodorous gas emissions from the farm. Then, the wastewater after secondary treatment continues to flow into the oxidation bin, and the air pump switch is turned on, and the air pump aerates the wastewater in the oxidation bin, thereby reducing anaerobic fermentation caused by the semi-enclosed environment in other sections of the body except the anaerobic section.

[0004] In order to prevent wastewater from producing methane due to anaerobic fermentation, the above-mentioned device for reducing methane emissions from dairy farm wastewater is equipped with an oxidation chamber, an air pump and an air supply pipe inside the body. However, the above-mentioned device for reducing methane emissions from dairy farm wastewater is not equipped with a stirring device. Without a stirring device, the organic matter, microorganisms and oxygen in the wastewater may not be fully contacted, resulting in an incomplete oxidation reaction, and thus the inability to completely degrade the organic matter in the wastewater, affecting the overall treatment effect of the wastewater.

[0012] Compared with the prior art, the present invention provides a contact oxidation tank for treating dairy wastewater, which has the following beneficial effects:

[0013] 1. The contact oxidation tank for dairy wastewater treatment is equipped with a stirring shaft and a stirring rod. After sufficient oxygen is supplied to the oxidation tank body, the motor is started. The output shaft of the motor drives the stirring shaft to rotate, and the stirring rod rotates accordingly to ensure that the organic matter, microorganisms and oxygen in the wastewater are fully mixed, making the oxidation reaction more uniform and efficient, reducing the chance of anaerobic fermentation, helping to accelerate the degradation process of organic matter, reduce the content of undegraded organic matter, and improve the water quality of the effluent.

[0014] 2. The contact oxidation tank for treating dairy wastewater is provided with a guide plate, a discharge pipe, a filter screen, a fixing block, a mounting block, a second bolt and a handle.
