Problems solved by technology

[0003] In addition, the traditional perforated aeration tube uses double-sided openings and is fixed on the bottom of the pool. The horizontal thrust generated by aeration on one side is offset by the horizontal thrust generated by aeration on the other side, which does not work effectively, resulting in energy waste.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] This embodiment of the present invention is an aeration system for a biological contact oxidation tank, which mainly includes a rotary aeration device 3 with a self-rotating function, and a main aeration pipe 1 , an aeration branch pipe 2 and a bearing 4 . . The rotary aeration device 3 with self-rotation function includes a rotating tee, the middle section of which is open upwards, connected with the branch pipe 2 through the bearing 4, so that the rotary aeration device 3 is located below the aeration branch pipe. Both sides of the rotating tee are respectively connected to the first perforated aeration pipe and the second perforated aeration pipe. The lengths of the first perforated aeration tube and the second perforated aeration tube are determined according to the distance between the aeration branch tubes, and the lengths of the first per...

Abstract

The invention discloses an aeration system for a biological contact oxidation pond. The aeration system is characterized in that each aeration branch pipe is at least connected with one group of rotary aeration devices; each rotary aeration device comprises a rotary T joint; an opening at a middle end of the rotary T joint faces upwards; the rotary T joint is connected with each aeration branch pipe through a bearing; one end of the rotary T joint is connected with a first perforated aeration pipe, and the other end of the rotary T joint is connected with a second perforated aeration pipe; openings of the first perforated aeration pipe and the second perforated aeration pipe face two sides respectively, so that perforated aeration pipe can be driven by gas counter-acting force generated bythe rotary aeration device during aeration to form automatic rotation. The aeration system is mainly applied to a biological pretreatment process in water treatment; aeration pipes are distributed onthe bottom of the biological contact oxidation pond, the aeration pipes are driven to rotate by the gas counter-acting force generated during single-side aeration; an aeration area is enlarged, effective fluidizationsulfurization of a biological stuffing is ensured; sludge is prevented from depositing on the bottom of the biological contact oxidation pond.

Description

technical field [0001] The invention relates to an aeration system for a biological contact oxidation tank. This system is mainly used in the biological pretreatment process of water treatment. By arranging a rotating aeration tube at the bottom of the tank, the gas reaction force generated during aeration is used to push the aeration tube to rotate, which expands the aeration area and ensures the biofilling. Effective fluidization can avoid mud accumulation at the bottom of the pool. Background technique [0002] Biological contact oxidation pond is one of the common treatment structures in water plants. It strengthens the removal of organic matter and ammonia nitrogen in water through biological action, so it is a widely used treatment structure in the water pretreatment process. In order to improve the effect of biological treatment, biological fillers are often added to the pool and properly aerated. Biofiller is mainly composed of carrier and biofilm, and the activity...
