A kind of multiple organic wastewater treatment system

Abstract

The invention discloses a multiplexed organic wastewater treatment system, which belongs to the technical field of organic wastewater treatment. A multiplexed organic wastewater treatment system uses an electric push rod to repeatedly extend and shorten, so that the outer protection cylinder moves up and down, and the aeration disc Translate vertically and drive the rack to move, so that the one-sided stirring paddle stirs the organic wastewater in the aeration tank, and the air can be sucked into the connecting cylinder through the blower, so that the air is blown into the aeration tank through the ventilation holes, and the aeration disc During the moving process, the aeration pan will be in contact with the sponge pad, so that the sponge pad will clean the sludge attached to the surface of the aeration pan, and the uninterrupted exhaust through the ventilation holes will make the sludge on the sponge pad be washed away, which can change The position of the aeration pan in the aeration tank, and the stirring of the wastewater, increases the contact area between the air and the sewage, and makes the vent holes on the aeration pan not easy to be blocked, which can make the aeration treatment of the organic sewage more sufficient .

Description

technical field [0001] The invention relates to the technical field of organic wastewater treatment, and more specifically relates to a multi-component organic wastewater treatment system. Background technique [0002] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. Organic wastewater generally refers to wastewater with a concentration of more than 2000mg / L discharged from industries such as papermaking, leather and food. Wastewater treatment is Use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources. [0003] The activated sludge method for biological treatment of organic wastewater has the advantages of good water quality and easy maintenance of the device, so it has been widely used in sewage treatment, industrial wastewa...

AI Technical Summary

Problems solved by technology

[0004] At present, when organic sewage is treated by the activated sludge method, it is necessary to aerate the wastewater first. Aeration refers to increasing the contact area between water and air by aerating water or mechanical stirring, which is an aerobic biological treatment of wastewater. In the intermediate process, an aeration disc is usually placed in the aeration tank, so that air is introduced into the water through the aeration disc. In the prior art, the position of the aeration disc is usually placed at the bottom of the aeration tank, and its position is not easy Change, the gas introduced is gradually consumed from bottom to top, which may reduce the reaction rate of wastewater and air in the upper layer. Adhering to the surface of the aeration pan, it is easy to block the ventilation holes on the aeration pan
