An aerobic treatment equipment and treatment process based on garbage station sewage treatment

Abstract

The present invention discloses an aerobic treatment device and treatment process for garbage station sewage treatment, and relates to the technical field of aerobic sewage treatment. The aerobic treatment device and treatment process for garbage station sewage treatment, through the mutual cooperation between an aeration mechanism, a lower baffle mechanism, and an attachment rod mechanism, aerates the sewage by the aeration mechanism, generating a large number of tiny air bubbles. As the air bubbles rise, the aeration mechanism can promptly puncture some of the passing air bubbles, causing the air bubbles to rupture rapidly. Unpunctured air bubbles continue to rise, and as they pass through the lower baffle mechanism, they are further punctured by the lower baffle mechanism, releasing oxygen within the air bubbles, which is then quickly dissolved into the sewage, increasing the dissolved oxygen in the sewage. This dual rupture mechanism improves oxygen utilization efficiency, reduces oxygen waste caused by air bubble escape, and provides the necessary oxygen conditions for the active metabolism of aerobic bacteria.

Description

Technical Field

[0001] The present invention relates to the technical field of aerobic sewage treatment, and in particular to aerobic treatment equipment and a treatment process based on garbage station sewage treatment. Background Art

[0002] With the acceleration of urbanization today, garbage disposal stations have heavy tasks. If the sewage they produce is not handled properly, it will pose a serious threat to the environment and health. Therefore, it is crucial to effectively treat the sewage from garbage stations. There are generally two ways to treat sewage, one is aerobic treatment and the other is anaerobic treatment. Aerobic treatment refers to the use of the metabolic activities of aerobic microorganisms under aerobic conditions to degrade organic matter in sewage, thereby purifying the water quality. Sludge will be produced in the process, which can be converted into organic fertilizer after further treatment to achieve resource reuse.

[0003] The sewage treatment aerobic tank disclosed in the patent application with reference publication number CN210419450U is equipped with an upper aerobic tank, a lower aerobic tank, and an aerobic tank. A stirring shaft is used for sufficient stirring, and an aeration device is used for preliminary oxygen supply reaction. The sewage then enters the upper part of the aerobic tank for further sufficient reaction with the aerobic bacterial sludge. The bacterial sludge is adsorbed on the brush and will not be deposited at the bottom of the aerobic tank. No additional aeration device is required, and the sewage is fully oxidized and decomposed.

[0004] A comprehensive analysis of the above reference patents reveals the following defects:

[0005] Existing aerobic treatment equipment and treatment processes based on garbage station sewage treatment are usually composed of a treatment box, an aeration mechanism, and an attachment rod mechanism that provides a growth attachment surface for aerobic bacteria. In the process of aerating the sewage using the aeration mechanism, a large number of air bubbles containing oxygen are generated. However, it is difficult to fully and timely puncture the air bubbles, resulting in many air bubbles rising and escaping directly without breaking. The oxygen utilization efficiency is low, and as the degradation proceeds, excessive sludge will accumulate on the surface of the attachment rod mechanism, making it difficult to conveniently and effectively clean the surface of the attachment rod mechanism regularly, which will hinder the growth of aerobic bacteria and the degradation of organic matter. Therefore, it is necessary to provide an aerobic treatment equipment and treatment process based on garbage station sewage treatment to solve the above technical problems. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the present invention provides an aerobic treatment device and treatment process based on garbage station sewage treatment, which solves the problem that a large number of air bubbles containing oxygen are generated in the process of aerating sewage using an aeration mechanism, but it is difficult to fully and timely puncture the air bubbles, resulting in many air bubbles rising and escaping directly without being broken, resulting in low oxygen utilization efficiency.

[0020] The present invention also provides an aerobic treatment process based on garbage station sewage treatment, using aerobic treatment equipment based on garbage station sewage treatment, and the specific process includes the following steps:

[0021] Step 1: The wastewater from the garbage station is input into the lower part of the inner cavity of the treatment box through the sewage inlet pipe. The wastewater then flows upward through the lower baffle mechanism and immerses the attachment rod mechanism located below the upper baffle. During this process, an external blower is used to send air into the aeration mechanism, which aerates the wastewater and produces a large number of fine air bubbles.

[0022] Step 2: As the air bubbles rise, the aeration mechanism promptly punctures some of the passing air bubbles, causing them to burst quickly. The oxygen inside the air bubbles is released and quickly dissolves into the sewage. The unpunctured air bubbles continue to rise and are further punctured by the lower baffle mechanism as they pass through. The oxygen inside these air bubbles dissolves into the water, thereby rapidly increasing the dissolved oxygen in the sewage and providing sufficient oxygen for the aerobic bacteria in the sewage.

[0023] Step 3: The attachment rod mechanism provides a growth and attachment environment for aerobic bacteria, allowing the microorganisms in the sewage to gradually accumulate on the surface of the attachment rod mechanism and form a dense biofilm. Aerobic bacteria actively metabolize on the biofilm, thereby degrading organic matter in the sewage and achieving the purpose of purifying the water quality. Sludge is produced in the process, and the purified water is eventually discharged through the liquid outlet pipe.

[0024] Beneficial effects

[0025] The present invention provides an aerobic treatment device and process for treating wastewater at garbage stations. Compared with the existing technology, it has the following advantages:

[0026] 1. An aerobic treatment equipment and treatment process based on garbage station sewage treatment, through the mutual cooperation between the aeration mechanism, the lower baffle mechanism and the attachment rod mechanism, the aeration mechanism aerates the sewage to generate a large number of small air bubbles. During the rising process of the air bubbles, the aeration mechanism can timely puncture some of the passing air bubbles, causing the air bubbles to burst quickly. The unpunctured air bubbles continue to rise, and in the process of passing through the lower baffle mechanism, they are further punctured by the lower baffle mechanism, so that the oxygen in the air bubbles is released, which is quickly dissolved into the sewage, increasing the dissolved oxygen in the sewage. This double rupture mechanism improves the utilization efficiency of oxygen, reduces the oxygen waste caused by the escape of air bubbles, and provides the necessary oxygen conditions for the active metabolism of aerobic bacteria. The attachment rod mechanism provides a good growth and attachment environment for aerobic bacteria, so that the microorganisms in the sewage gradually accumulate on the surface of the attachment rod mechanism and form a dense biofilm. This biofilm not only increases the contact area between the microorganisms and the sewage, but also promotes the synergistic effect between the microorganisms, thereby better promoting the rapid degradation of organic matter in the sewage and the removal of pollutants.

[0027] 2. An aerobic treatment equipment and treatment process based on garbage station sewage treatment. Through the mutual cooperation between the microporous aeration plate, the filter screen, the impeller, the curved brush and the first needle, aerobic bacteria will produce sludge when degrading organic matter in the sewage. The filter screen can prevent the sludge from clogging the micropores on the surface of the microporous aeration plate, thereby ensuring the normal aeration effect of the microporous aeration plate. As the sewage flows upward, it can impact the impeller with the flow of water, so that the impeller drives the curved brush to rotate. The rotating curved brush can promptly scrape the surface of the filter screen to avoid sludge accumulation on the surface of the filter screen, so that the air bubbles generated by aeration can pass through the filter screen normally. Moreover, under the action of the first needle, the air bubbles can be punctured in time during the process of the air bubbles passing through the filter screen, so that the oxygen is quickly released, dissolved in the sewage and flows upward.

[0028] 3. An aerobic treatment equipment and treatment process based on garbage station sewage treatment. Through the mutual cooperation between the guide port, the spring, the mesh disk and the second needle, when the sewage flows upward through the guide port, under the impact of the water flow, the elastic action of the spring and the impact of the gas, the mesh disk will vibrate up and down, and the second needle will vibrate up and down accordingly. During the process, the second needle can further puncture the passing air bubbles, achieving a double rupture effect, ensuring that the oxygen in the air bubbles is fully released during the upward process, reducing oxygen escape and improving oxygen utilization.

[0029] 4. An aerobic treatment equipment and treatment process based on garbage station sewage treatment, through the mutual cooperation between the vertical shaft, fiber ball assembly, curved blades, curved scraper and L-shaped pipe, multiple fiber ball assemblies provide a good growth and attachment environment for aerobic bacteria, which can better degrade organic matter in sewage. The sludge generated in the process is adsorbed on the surface of the fiber ball assembly. When the sludge on the surface of the fiber ball assembly accumulates to a certain extent, the curved scraper and elastic scraper are used to push and scrape the fiber ball assembly. During the process, the solenoid valves on the sewage inlet pipe and the liquid outlet pipe are closed, and the solenoid valves on the water injection pipe and the liquid discharge pipe are opened. Clean water is introduced into the upper part of the top plate through the water injection pipe. The water flows to the right and impacts the curved blades, causing the curved blades and sleeves on each attachment rod mechanism to rotate, thereby driving the curved scraper to rotate around the outer walls of the two hemispherical shells in the corresponding fiber ball assembly, pushing and scraping the short fiber filaments, and gradually scraping off the sludge adsorbed on the surface of the short fiber filaments. The clean water passes through each L-shaped pipe and is finally sprayed downward through the nozzle to rinse the fiber ball assembly again, thereby achieving convenient and effective cleaning of the fiber ball assembly, avoiding excessive sludge accumulation on the surface of the fiber ball assembly, and preventing excessive sludge from hindering the growth of aerobic bacteria and the degradation of organic matter.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] The present invention provides two technical solutions:

[0052] like Figures 1 to 5 The first embodiment is shown: an aerobic treatment device based on wastewater treatment at a garbage station, comprising a treatment box 1, and further comprising:

[0053] A sewage inlet pipe 2 is fixedly arranged at the bottom left side of the front end of the treatment box 1 and is used to input garbage station sewage into the treatment box 1. A liquid outlet pipe 3 is fixedly connected to the upper right side of the treatment box 1. An upper partition 7 is fixedly arranged between the upper side walls of the inner cavity of the treatment box 1. A top plate 8 located directly above the upper partition 7 is fixedly arranged between the upper side walls of the inner cavity of the treatment box 1. A number of L-shaped tubes 11 are evenly fixed on the top of the upper partition 7 from front to back. The bottom of each L-shaped tube 11 is fixedly connected to a number of nozzles 12 that penetrate to the bottom of the upper partition 7 from left to right. A water injection pipe 14 is fixedly connected to the upper left side of the treatment box 1 and above the top plate 8. A liquid discharge pipe 15 is fixedly connected to the lower left side of the treatment box 1;

[0054] The aeration mechanism 4 is provided at the lower part of the inner cavity of the treatment box 1 and is used to provide oxygen for the aerobic bacteria in the treatment box 1;

[0055] The lower baffle mechanism 5 is provided at the lower part of the inner cavity of the treatment box 1 and is located directly above the aeration mechanism 4, and is used to puncture the air bubbles passing through, so that the oxygen in the air bubbles can be quickly dissolved into the water;

[0056] Several attachment rod mechanisms 6 are evenly arranged between the top of the lower partition mechanism 5 and the top of the inner cavity of the treatment box 1 to provide an environment for the growth and attachment of aerobic bacteria, so that the microorganisms in the sewage form a dense biofilm on the surface of the attachment rod mechanism 6.

[0057] Through the mutual cooperation between the aeration mechanism 4, the lower baffle mechanism 5 and the attachment rod mechanism 6, the aeration mechanism 4 aerates the sewage to generate a large number of small air bubbles. During the rising process of the air bubbles, the aeration mechanism 4 can timely puncture some of the passing air bubbles, causing the air bubbles to burst quickly. The air bubbles that have not been punctured continue to rise. In the process of passing through the lower baffle mechanism 5, they are further punctured by the lower baffle mechanism 5, so that the oxygen in the air bubbles is released, thereby quickly dissolving into the sewage, increasing the dissolved oxygen in the sewage. This double rupture mechanism improves the utilization efficiency of oxygen, reduces the oxygen waste caused by the escape of air bubbles, and provides the necessary oxygen conditions for the active metabolism of aerobic bacteria. The attachment rod mechanism 6 provides a good growth and attachment environment for aerobic bacteria, so that the microorganisms in the sewage gradually accumulate on the surface of the attachment rod mechanism 6 and form a dense biofilm. This biofilm not only increases the contact area between the microorganisms and the sewage, but also promotes the synergistic effect between the microorganisms, thereby better promoting the rapid degradation of organic matter in the sewage and the removal of pollutants.

The bronchial tubes 42 are respectively located directly below the corresponding carrier plates 41. The top of each bronchial tube 42 is fixedly provided with a number of microporous aeration disks 44 from front to back. Each microporous aeration disk 44 is fixedly passed through the top of the corresponding carrier plate 41. The outside of each microporous aeration disk 44 is provided with a protective cover assembly 46 located at the top of the carrier plate 41. Each protective cover assembly 46 includes a filter screen cover 461. The filter screen cover 46 1 is set on the outside of the microporous aeration plate 44 and is connected to the top of the supporting plate 41 by bolts. The top of the filter screen cover 461 is rotatably provided with a shaft 462, and the top of the shaft 462 is fixedly provided with an impeller 463. The left bottom of the shaft 462 is fixedly provided with an arc-shaped brush 464. The lower side wall of the arc-shaped brush 464 contacts the outer wall of the filter screen cover 461. The inner wall of the filter screen cover 461 is evenly fixed with a plurality of first needles 465. The lower partition mechanism 5 includes a lower partition 51, which is fixedly connected between the inner walls of the processing box 1. A plurality of guide openings 52 are evenly opened inside the lower partition 51. A bracket 53 is fixedly provided between the inner walls of each guide opening 52, and a mesh disk 55 is provided just above each guide opening 52. The outer circle of the bottom of each mesh plate 55 is fixedly connected to the top of the lower partition 51 through a number of springs 54. A number of second needles 56 are fixedly provided at the bottom of each mesh plate 55. A number of guide ports 52 are respectively located directly above the corresponding microporous aeration plates 44. Each attachment rod mechanism 6 includes a vertical shaft 61. The bottom of the vertical shaft 61 is fixedly connected to the middle of the top of the corresponding bracket 53. The top of the vertical shaft 61 is fixedly connected to the top of the inner cavity of the treatment box 1. The outside of the vertical shaft 61 is evenly sleeved with a number of fiber ball assemblies 62 located between the lower partition 51 and the upper partition 7 from bottom to top. The upper part of the vertical shaft 61 is rotatably sleeved with a sleeve 63. The sleeve 63 rotates and passes through between the upper partition 7 and the top plate 8. The top of the sleeve 63 is rotatably connected to the top of the inner cavity of the treatment box 1.Several curved blades 64 are evenly fixed around the sidewall of the sleeve 63, located above the top plate 8. Each sidewall of the fiber ball assembly 62 is provided with a curved scraper 65. Each curved scraper 65 is fixedly provided with an elastic scraper strip 66 on the side close to the vertical shaft 61. A connecting sleeve 67 is rotatably provided on the outside of the vertical shaft 61 and directly below each fiber ball assembly 62. The upper and lower ends of each connecting sleeve 67 are respectively fixedly connected to the adjacent curved scraper 65. The top of the uppermost curved scraper 65 is fixedly connected to the bottom of the sleeve 63. Each fiber ball assembly 62 includes two hemispherical shells 621. Several short fiber filaments 622 are fixedly provided on the outer walls of the two hemispherical shells 621. The two hemispherical shells 621 are threadedly connected by four fastening bolts 623.

[0059] Through the mutual cooperation between the microporous aeration plate 44, the filter screen cover 461, the impeller 463, the curved brush 464 and the first needle 465, aerobic bacteria will produce sludge when degrading organic matter in the sewage. The filter screen cover 461 can prevent the sludge from clogging the micropores on the surface of the microporous aeration plate 44, ensuring the normal aeration effect of the microporous aeration plate 44. As the sewage flows upward, it can impact the impeller 463 with the flow of water, causing the impeller 463 to drive the curved brush 464 to rotate. The rotating curved brush 464 can promptly scrape the surface of the filter screen cover 461, avoiding the accumulation of sludge on the surface of the filter screen cover 461, so that the air bubbles generated by aeration can pass through the filter screen cover 461 normally. , and under the action of the first needle 465, when the air bubbles pass through the filter screen 461, the first needle 465 can puncture the air bubbles in time, so that the oxygen is quickly released, dissolved in the sewage and flows upward. Through the mutual cooperation between the guide port 52, the spring 54, the mesh plate 55 and the second needle 56, when the sewage flows upward through the guide port 52, under the impact of the water flow, the elastic action of the spring 54 and the impact of the gas, the mesh plate 55 will vibrate up and down, and the second needle 56 will vibrate up and down accordingly. During the process, the second needle 56 can further puncture the passing air bubbles, achieving a double rupture effect, ensuring that the oxygen in the air bubbles is released upward. During the ascension process, oxygen is fully released, which reduces oxygen escape and improves oxygen utilization. Through the mutual cooperation between the vertical shaft 61, the fiber ball assembly 62, the curved blades 64, the curved scraper 65 and the L-shaped tube 11, multiple fiber ball assemblies 62 provide a good growth and attachment environment for aerobic bacteria, which can better degrade organic matter in sewage. The sludge generated during the process is adsorbed on the surface of the fiber ball assembly 62. When the sludge on the surface of the fiber ball assembly 62 accumulates to a certain extent, the curved scraper 65 and the elastic scraper 66 are used to push and scrape the fiber ball assembly 62. During the process, the solenoid valves on the sewage inlet pipe 2 and the liquid outlet pipe 3 are closed, and the solenoid valves on the water injection pipe 14 and the liquid discharge pipe 15 are opened. The water pipe 14 introduces clean water into the upper part of the top plate 8. The water flows to the right and impacts the curved blades 64, causing the curved blades 64 and sleeves 63 on each attachment rod mechanism 6 to rotate, thereby driving the curved scraper 65 to rotate around the outer walls of the two hemispherical shells 621 in the corresponding fiber ball assembly 62, pushing and scraping the short fiber filaments 622, and gradually scraping off the sludge adsorbed on the surface of the short fiber filaments 622. The clean water passes through each L-shaped tube 11 and is finally sprayed downward through the nozzle 12 to rinse the fiber ball assembly 62 again, thereby achieving effective cleaning of the fiber ball assembly 62, avoiding excessive sludge accumulation on the surface of the fiber ball assembly 62, and preventing excessive sludge from hindering the growth of aerobic bacteria and the degradation of organic matter.

[0060] The embodiment of the present invention further provides an aerobic treatment process based on wastewater treatment at a garbage station, using aerobic treatment equipment based on wastewater treatment at a garbage station. The specific process includes the following steps:

[0061] Step 1: The wastewater from the garbage station is input into the lower part of the inner cavity of the treatment box 1 through the sewage inlet pipe 2. The wastewater then flows upward through the lower baffle mechanism 5 and immerses the fiber ball assembly 62. During this process, an external blower is used to send air into the aeration mechanism 4, which aerates the wastewater to produce a large number of fine air bubbles.

[0062] Step 2: During the rising process of air bubbles, the aeration mechanism 4 punctures some of the passing air bubbles in time. During the process, since aerobic bacteria will produce sludge when degrading organic matter in sewage, the filter screen cover 461 can prevent the sludge from clogging the micropores on the surface of the microporous aeration plate 44, ensuring the normal aeration effect of the microporous aeration plate 44. Since the sewage flows upward, it can impact the impeller 463 with the flow of water, so that the impeller 463 drives the arc-shaped brush 464 to rotate. The rotating arc-shaped brush 464 can timely scrape the surface of the filter screen cover 461 to avoid sludge accumulation on the surface of the filter screen cover 461, so that the air bubbles generated by aeration can pass through the filter screen cover 461 normally. And under the action of the first needle 465, when the air bubbles pass through the filter screen cover 461, the first needle The needle 465 can puncture the air bubbles in time, causing the air bubbles to burst quickly, and the oxygen in the air bubbles is released, thereby quickly dissolving into the sewage. The sewage containing dissolved oxygen flows upward, and the air bubbles that have not been punctured continue to rise. In the process of passing through the lower partition mechanism 5, they are further punctured by the lower partition mechanism 5. In this process, under the impact of the water flow, the elastic action of the spring 54, and the impact of the gas, the mesh plate 55 will vibrate up and down, and the second needle 56 will vibrate up and down accordingly. In this process, the second needle 56 can further puncture the passing air bubbles, achieving a double rupture effect, ensuring that the oxygen in the air bubbles is fully released during the rising process and dissolved into the water, thereby quickly increasing the dissolved oxygen in the sewage and providing sufficient oxygen for the aerobic bacteria in the sewage.

[0063] Step 3, wherein the plurality of fiber ball components 62 provide a good growth and attachment environment for aerobic bacteria, so that the microorganisms in the sewage gradually accumulate on the surface of the fiber ball component 62 and form a dense biofilm. The aerobic bacteria actively metabolize on the biofilm, thereby degrading the organic matter in the sewage and achieving the purpose of purifying the water quality. The purified water is finally discharged through the outlet pipe 3. The sludge generated in the process of aerobic bacteria degrading the organic matter is adsorbed on the surface of the fiber ball component 62. When the sludge on the surface of the fiber ball component 62 accumulates to a certain extent, the curved scraper 65 and the elastic scraper 66 are used to push and scrape the fiber ball component 62 to clean it. During the process, the solenoid valves on the sewage inlet pipe 2 and the liquid outlet pipe 3 are first closed, and the solenoid valves on the water injection pipe 14 and the liquid discharge pipe 15 are opened. The water is discharged to the top plate 8 through the water injection pipe 14. Clean water is introduced into the upper part, and the water flows to the right, impacting the arc blade 64, causing the arc blade 64 and the sleeve 63 on each attachment rod mechanism 6 to rotate, thereby driving the arc scraper 65 to rotate around the outer wall of the two hemispherical shells 621 in the corresponding fiber ball assembly 62, pushing and scraping the short fiber filaments 622, and gradually scraping off the sludge adhered to the surface of the short fiber filaments 622. The clean water passes through each L-shaped tube 11 and is finally sprayed downward through each nozzle 12 to rinse the fiber ball assembly 62 again, thereby achieving effective cleaning of the fiber ball assembly 62, avoiding excessive sludge accumulation on the surface of the fiber ball assembly 62, and preventing excessive sludge from hindering the growth of aerobic bacteria and the degradation of organic matter. The wastewater generated by cleaning is finally discharged through the drain pipe 15, completing the cleaning of the fiber ball assembly 62.

An aerobic treatment process based on wastewater treatment at a garbage station, characterized by: Using the aerobic treatment equipment based on garbage station sewage treatment as described in any one of claims 1 to 5, the process includes the following steps: Step 1: The wastewater from the garbage station is input into the lower part of the inner cavity of the treatment box through the sewage inlet pipe. The wastewater then flows upward through the lower baffle mechanism and immerses the attachment rod mechanism located below the upper baffle. During this process, an external blower is used to send air into the aeration mechanism, which aerates the wastewater and produces a large number of fine air bubbles. Step 2: As the air bubbles rise, the aeration mechanism promptly punctures some of the passing air bubbles, causing them to burst quickly. The oxygen inside the air bubbles is released and quickly dissolves into the sewage. The unpunctured air bubbles continue to rise and are further punctured by the lower baffle mechanism as they pass through. The oxygen inside these air bubbles dissolves into the water, thereby rapidly increasing the dissolved oxygen in the sewage and providing sufficient oxygen for the aerobic bacteria in the sewage. Step 3: The attachment rod mechanism provides a growth and attachment environment for aerobic bacteria, allowing the microorganisms in the sewage to gradually accumulate on the surface of the attachment rod mechanism and form a dense biofilm.
