Description

Technical Field

[0001] This utility model relates to the field of aeration tank technology, specifically to a rapid deep aeration tank for water treatment. Background Technology

[0002] The aeration tank is the core structure of the activated sludge wastewater treatment process, primarily used to remove organic pollutants from wastewater. Its core principle is to continuously introduce air into the wastewater through the aeration system. This provides sufficient oxygen for the aerobic microorganisms within the tank, meeting their metabolic needs, and simultaneously ensures thorough mixing and contact between the wastewater and activated sludge, forming a suspended liquid. Under suitable temperature and pH conditions, the aerobic microorganisms adsorb and decompose the organic matter in the wastewater, converting it into harmless substances such as carbon dioxide and water. Simultaneously, the microorganisms themselves multiply and grow, forming even more activated sludge.

[0003] Currently, most aeration tanks have significant limitations in aeration system design and operation, generally lacking the precise control capability for stratified aeration, making it difficult to achieve efficient deep aeration. Existing aeration methods mostly adopt a single-area, uniform air distribution mode, with air mostly concentrated in the upper layer of the water, failing to provide stratified supply according to the different oxygen requirements of wastewater at different depths within the tank. This results in a significant reduction in oxygen transport efficiency in the middle and lower layers of the tank, leading to uneven dissolved oxygen distribution. This deficiency makes it difficult for aerobic microorganisms in the tank to maintain an active metabolic state in the deeper water, not only affecting the decomposition efficiency of organic pollutants in wastewater but also potentially causing anaerobic reactions due to localized hypoxia, resulting in the risk of secondary pollution. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a rapid deep aeration tank for water treatment that can perform layered deep aeration, has a good aeration effect, and maintains the aeration state in the tank.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a rapid deep aeration tank for water treatment, comprising:

[0006] The pool body has an inlet pipe and an outlet pipe fixedly installed on its side wall, and an inlet pump and an outlet pump are respectively fixedly installed on the inlet pipe and the outlet pipe.

[0007] The mushroom block base is fixedly installed in the middle of the bottom surface of the pool, and several mushroom block troughs are provided on it;

[0008] Aeration discs are arranged at equal intervals around the center of the tank and are connected in sequence by air pipes. An air inlet pipe is fixedly installed on the air pipe.

[0009] Microporous aeration pipes are symmetrically arranged on both sides of the inside of the pool. The microporous aeration pipes on the same side are distributed in a stepped manner and are interconnected. Each microporous aeration pipe on the same side has an air inlet extending to the outside of the pool.

[0010] Furthermore, one end of the inlet pipe and the outlet pipe extend into the lower part of the pool body, and the other end extends out of the pool body.

[0011] Furthermore, the mycelium block grooves are evenly distributed, and mycelium blocks can be inserted into them.

[0012] Furthermore, the aeration disc is evenly distributed with several aeration holes.

[0013] Furthermore, the trachea surrounds the bacterial substrate in a square ring shape.

[0014] Furthermore, a heightening seat for supporting the microporous aeration pipe is fixedly provided on the inner side wall of the pool.

[0015] Compared with existing technologies, the advantages of this invention are as follows: Two types of aeration components are installed in the tank and distributed in layers. One type is evenly distributed around the central bacterial block, providing uniform aeration to the central area of ​​the tank and ensuring sufficient air contact between the wastewater and the surrounding bacteria block. The other type is distributed in a stepped pattern on both sides of the tank, aerating wastewater at different depths on both sides. The two types of components work together to achieve layered coverage throughout the entire tank. Both types of aeration components have optimized designs to improve performance. The aeration holes or micropores on the components disperse air into small bubbles, increasing the contact area with wastewater and improving oxygen transfer efficiency. Simultaneously, the aeration components have a fixed structure to prevent positional displacement due to water flow impact, ensuring stable aeration and continuously maintaining a uniform aeration state within the tank.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4A rapid deep aeration tank for water treatment includes: a tank body 1, with an inlet pipe 2 and an outlet pipe 3 fixedly installed on the side wall. An inlet pump 4 and an outlet pump 5 are respectively fixedly installed on the inlet pipe 2 and the outlet pipe 3. One end of the inlet pipe 2 and the outlet pipe 3 extends into the lower part of the tank body 1, allowing the water to be treated to enter from the bottom of the tank and the treated water to be discharged from the bottom of the tank, avoiding short circuit of water flow. The other end extends out of the tank body 1, which is convenient for connecting with external pipelines and improves the ease of equipment installation.

[0023] Combined with appendix Figure 1 Appendix Figure 2 The microbial block seat 6 is fixedly installed in the middle of the bottom surface of the pool body 1. Several microbial block grooves 7 are provided on it. The microbial block grooves 7 are evenly distributed and microbial blocks can be inserted into them, so that the inserted microbial blocks can be evenly dispersed in the pool body 1, ensuring that the microorganisms and sewage are in full contact. At the same time, the insertable design facilitates the replacement and maintenance of microbial blocks, reducing the later operating costs.

[0024] Combined with appendix Figure 1 Appendix Figure 2 Aeration discs 8 are arranged at equal intervals around the center of the tank body 1, and are connected sequentially by air pipes 9. Air inlet pipes 10 are fixedly installed on the air pipes 9. The aeration discs 8 have evenly distributed aeration holes, which can uniformly disperse air into small bubbles, increasing the contact area between air and wastewater; thereby improving oxygen transfer efficiency, providing sufficient oxygen for microorganisms in the tank, and accelerating wastewater purification. The air pipes 9 form a square ring around the bacterial block seat 6, allowing the aeration discs 8 to be evenly distributed around the bacterial block seat 6, ensuring that the wastewater around the bacterial block seat 6 is aerated, and avoiding localized hypoxia that could affect microbial activity.

[0025] Combined with appendix Figure 1 Appendix Figure 2 Microporous aeration pipes 11 are symmetrically arranged on both sides of the interior of the tank body 1. The microporous aeration pipes 11 on the same side are distributed in a stepped manner and are interconnected. Each microporous aeration pipe 11 on the same side has an air inlet 12 extending to the outside of the tank body 1 at its end. A support seat 13 for supporting the microporous aeration pipes 11 is fixed on the inner wall of the tank body 1 to ensure that the position of the microporous aeration pipes 11 is fixed, avoid uneven aeration caused by water flow impact, and improve aeration stability.

[0026] The specific implementation of this utility model is as follows: Water to be treated is transported to the interior of the tank 1 via the inlet pump 4 on the inlet pipe 2. The water flow rises slowly from the lower end of the tank 1, avoiding direct impact on internal components. Simultaneously, microbial blocks are inserted into several block grooves 7 on the block holder 6, ensuring the blocks are evenly dispersed within the tank 1, preparing for subsequent wastewater purification. Air is introduced through the air inlet pipe 10 on the air pipe 9 and the air inlet 12 of the microporous aeration pipe 11. The air pipe 9 drives the aeration discs 8, which are equidistantly distributed around the center of the tank 1. The aeration holes on the aeration discs 8 disperse the air into small bubbles, aerating the wastewater in the central area of ​​the tank 1. The microporous aeration pipes 11 on both sides of the tank 1 are arranged in a stepped pattern, continuously aerating wastewater at different depths on both sides under the fixed support of the riser seat 13. After the wastewater is degraded by microorganisms and fully aerated and purified in the tank 1, the water pump 5 on the water outlet pipe 3 is started to discharge the treated water from the bottom of the tank 1 through the water outlet pipe 3, thus completing a complete treatment process.
