An aeration tank with high biodegradation efficiency for high-concentration wastewater

Abstract

This invention relates to the field of aeration tank technology, specifically to an aeration tank with high biodegradation efficiency for high-concentration wastewater. The tank includes a main body, with a mixing component and a cleaning component installed on top. The mixing component includes a fixed plate, and a first servo motor is mounted on the upper surface of the fixed plate. The output end of the first servo motor is connected to a drive rod. Through the mixing component, the first and second stirring rods rotate in opposite directions, allowing the high-concentration wastewater in the aeration tank to mix thoroughly with oxygen, increasing the contact time between wastewater and oxygen, thereby improving the degradation efficiency. The cleaning component pushes foam on the wastewater surface to the edge of the tank, facilitating foam removal by workers and preventing them from missing foam in the tank, thus reducing labor intensity and improving work efficiency.

Description

Technical Field

[0001] This invention relates to the field of aeration tank technology, specifically to an aeration tank with high biodegradation efficiency for high-concentration wastewater. Background Technology

[0002] An aeration tank is a biochemical reactor designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by the people. The aeration tank contains high-concentration wastewater.

[0003] However, existing aeration tanks have steel pipes laid at the bottom, and oxygen is injected into the steel pipes. The oxygen enters the aeration tank through the holes on the surface of the steel pipes to degrade organic pollutants. The oxygen passes through the aeration tank and then enters the air. The liquid in the aeration tank has very little contact with oxygen, resulting in low degradation efficiency of organic pollutants in the aeration tank. It is necessary to repeatedly pass oxygen through the liquid in the aeration tank to degrade it. Summary of the Invention

[0004] The purpose of this invention is to provide an aeration tank with high biodegradation efficiency for high-concentration wastewater, so as to solve the problem of low oxygen degradation efficiency in aeration tanks mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The new type of aeration tank, through the setting of the mixing components, starts the No. 1 servo motor, the No. 1 servo motor drives the drive rod to rotate, the drive rod drives the No. 1 stirring rod to rotate, the drive rod drives the internal gear to rotate, the internal gear drives the No. 1 gear to rotate, the No. 1 gear drives the No. 2 gear to rotate, and the No. 2 gear drives the rotating rod and the No. 2 stirring rod to rotate. The No. 1 stirring rod and the No. 2 stirring rod rotate in opposite directions, so that the high-concentration sewage in the aeration tank can be fully mixed with oxygen, the contact time between sewage and oxygen is increased, and thus the degradation efficiency of sewage is improved.

[0016] (2) The new type of aeration tank, through the setting of the cleaning components, generates a large amount of foam in the aeration tank, which can start the No. 2 servo motor. The No. 2 servo motor drives the lead screw to rotate, the lead screw drives the nut pair to move, and the nut pair drives the guide block and the No. 2 filter plate to move. This can push the foam on the surface of the sewage to the edge of the tank, making it convenient for staff to clean the foam. This avoids the staff not being able to clean the foam in the tank, reduces labor intensity, and can push the foam together, thus improving work efficiency. Attached image description:
