Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and more specifically, to a wastewater treatment structure. Background Art

[0002] Pathogens (bacteria, viruses, etc.) that may be carried in wastewater can spread diseases and pose a threat to human health, especially domestic sewage and certain industrial wastewater, which may cause waterborne diseases if discharged without treatment.

[0003] When existing wastewater is treated, it usually needs to be discharged into an aeration tank to remove organic pollutants in the water through the activated sludge method under the action of oxygen. The activated sludge adsorbs and degrades the wastewater, converting the organic matter in the wastewater into harmless carbon dioxide, water and new microbial cells, thereby improving water quality and preparing for subsequent deep treatment or meeting emission standards.

[0004] In actual use of the prior art, when wastewater passes through activated sludge to remove organic pollutants, oxygen-assisted activated sludge oxidation is required to decompose the organic pollutants in the wastewater. Since part of the activated sludge will be deposited at the bottom of the wastewater and the oxygen content it is exposed to is less, the decomposition efficiency is relatively low. Therefore, a wastewater treatment structure is now proposed. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the utility model provides a wastewater treatment structure, which transports oxygen into a rotating pipe through an air inlet pipe and sprays it out through nozzles on a straight pipe and an L-shaped pipe. The waterproof and breathable membrane can prevent wastewater from flowing back into the pipe through the nozzle. When the straight pipe rotates, it drives oxygen to be evenly sprayed into the wastewater, and at the same time forms a counterattack with the oxygen sprayed from the L-shaped pipe. The two airflows are staggered and mixed together to stir the oxygen and fully mix it with the wastewater, providing sufficient dissolved oxygen to aerobic microorganisms in the wastewater. The aerobic microorganisms will oxidize and decompose organic pollutants in the wastewater, thereby purifying the water quality, and can improve the efficiency and effect of sewage treatment.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A wastewater treatment structure comprises an aeration tank, wherein a mounting plate is fixedly connected to the upper surface of the aeration tank, a mixing mechanism is arranged in the inner cavity of the aeration tank, and a driving mechanism is arranged on the upper surface of the mounting plate; the mixing mechanism comprises a straight-line rotating joint fixedly connected to the bottom of the aeration tank, a rotating tube is connected to the upper end of the straight-line rotating joint, an L-shaped rotating joint is connected to the upper end of the rotating tube, an L-shaped tube is connected to the outer surface of the straight-line rotating joint, an straight-line tube is connected to the outer surface of the rotating tube, a nozzle is connected to the outer surface of the L-shaped tube and the straight-line tube, and a waterproof breathable membrane is fixedly connected to one end of the nozzle; the driving mechanism comprises a driven gear fixedly connected to the outer surface of the rotating tube, and a driving gear is meshedly connected to the outer surface of the driven gear.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) In this scheme, the motor drives the driving gear to rotate, and drives the driven gear and the rotating tube to rotate under the cooperation of the straight rotating joint and the L-shaped rotating joint. The rotation of the rotating tube will drive the straight tube to rotate to fully mix the wastewater and microorganisms in the aeration tank, increase the chance of contact between pollutants and microorganisms, and convert the organic matter in the wastewater into harmless carbon dioxide, water and new microbial cells through microbial adsorption and degradation, thereby purifying the water quality.

[0018] (2) In this scheme, oxygen is transported into the rotating pipe through the air inlet pipe and sprayed out through the nozzles on the straight pipe and the L-shaped pipe. The waterproof breathable membrane can prevent the wastewater from flowing back into the pipe through the nozzle. When the straight pipe rotates, it will drive the oxygen to be evenly sprayed into the wastewater, and at the same time, it will form a counter-action with the oxygen sprayed from the L-shaped pipe. The two air flows are staggered and mixed together to stir the oxygen and fully mix it with the wastewater, providing sufficient dissolved oxygen to the aerobic microorganisms in the wastewater. The aerobic microorganisms will oxidize and decompose the organic pollutants in the wastewater, thereby purifying the water quality, which can improve the efficiency and effect of sewage treatment. At the same time, it can also disperse the microorganisms that have accumulated and gathered together, so that they can be further mixed with the wastewater. BRIEF DESCRIPTION OF THE DRAWINGS
