Description

Technical Field

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

[0003] The aerobic tank for sewage treatment disclosed in the patent application with reference publication number CN210419450U is provided with an aerobic tank upper part, an aerobic tank lower part, and an aerobic tank lower part. A stirring shaft is used for sufficient stirring, and an aeration device is used for preliminary oxygen supply reaction, and then the sewage enters the aerobic tank upper part 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] Comprehensive analysis of the above reference patents shows 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 will be generated. However, it is difficult to fully and timely puncture the air bubbles, resulting in many air bubbles directly rising and escaping without being broken. The oxygen utilization efficiency is low, and as the degradation proceeds, too much sludge will accumulate on the surface of the attachment rod mechanism. It is 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

Sludge will be produced in the process, and the purified water will eventually be discharged through the liquid outlet pipe.

[0024] Beneficial Effects

[0025] The present invention provides an aerobic treatment device and treatment process based on wastewater treatment in garbage stations. Compared with the prior art, it has the following beneficial effects:

[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. In the process of the air bubbles rising, the aeration mechanism can timely puncture some of the passing air bubbles, so that the air bubbles burst quickly. The unpunctured air bubbles continue to rise. 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, and then 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 device and treatment process based on garbage station sewage treatment. Through the mutual cooperation between the microporous aeration plate, the filter screen cover, the impeller, the arc-shaped brush and the first needle, aerobic bacteria will produce sludge when degrading organic matter in the sewage. The filter screen cover 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 arc-shaped brush to rotate. The rotating arc-shaped brush can timely scrape the surface of the filter screen cover to avoid the accumulation of sludge on the surface of the filter screen cover, so that the air bubbles generated by aeration can pass through the filter screen cover normally. Moreover, under the action of the first needle, the first needle can timely puncture the air bubbles during the process of the air bubbles passing through the filter screen cover, so that the oxygen is quickly released, dissolved in the sewage and flows upward.

[0028] 3. An aerobic treatment device 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 to achieve a double rupture effect, ensuring that the oxygen in the air bubbles is fully released during the rising 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 cooperation between the vertical shaft, fiber ball assembly, arc blade, arc 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 fiber ball assembly is pushed and scraped by the arc scraper and the elastic scraper. During the process, the electromagnetic valves on the sewage inlet pipe and the liquid outlet pipe are closed, and the electromagnetic 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 arc blades, causing the arc blades and sleeves on each attachment rod mechanism to rotate, thereby driving the arc 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. 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 be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 of the left 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 plurality of L-shaped tubes 11 are evenly fixedly arranged 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 plurality of nozzles 12 penetrating 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 located 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 arranged 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;

[0056] A plurality of attachment rod mechanisms 6 are evenly arranged between the top of the lower baffle mechanism 5 and the top of the inner cavity of the treatment box 1 to provide a growth and attachment environment for 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 among 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. In the process of the air bubbles rising, the aeration mechanism 4 can timely puncture some of the passing air bubbles, so that the air bubbles burst quickly, and the unpunctured air bubbles 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 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 brush 464, and the lower side wall of the arc 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, and the lower partition 51 is fixedly connected between the inner walls of the processing box 1. The interior of the lower partition 51 is evenly provided with a plurality of guide openings 52, and a bracket 53 is fixedly provided between the inner walls of each guide opening 52. A mesh plate 55 is provided directly 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 plurality of springs 54, and a plurality of second needles 56 are fixedly arranged at the bottom of each mesh plate 55. A plurality 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, and 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 plurality of fiber ball assemblies 62 located between the lower partition 51 and the upper partition 7 from bottom to top, and a sleeve 63 is rotatably sleeved on the upper part of the vertical shaft 61, and the sleeve 63 rotates and passes through between the upper partition 7 and the top plate 8, and the top of the sleeve 63 is rotatably connected to the top of the inner cavity of the treatment box 1.A number of arc-shaped blades 64 located above the top plate 8 are evenly fixedly arranged on the side wall of the sleeve 63. A side wall of each fiber ball assembly 62 is provided with an arc-shaped scraper 65. An elastic scraper strip 66 is fixedly arranged on the side of each arc-shaped scraper 65 close to the vertical axis 61. A connecting sleeve 67 is rotatably sleeved on the outside of the vertical axis 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 arc-shaped scraper 65. The top of the uppermost arc-shaped scraper 65 is fixedly connected to the bottom of the sleeve 63. Each fiber ball assembly 62 includes two hemispherical shells 621. The outer walls of the two hemispherical shells 621 are fixedly provided with a number of short fiber filaments 622. The two hemispherical shells 621 are threadedly connected by four fastening bolts 623.

[0059] Through the cooperation among the microporous aeration disk 44, the filter screen cover 461, the impeller 463, the arc-shaped 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 disk 44, thereby ensuring the normal aeration effect of the microporous aeration disk 44. As 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, thereby preventing the accumulation of sludge on the surface of the filter screen cover 461, and allowing the air bubbles generated by aeration to pass through the filter screen cover 461 normally. , and under the action of the first thorn needle 465, when the air bubbles pass through the filter screen 461, the first thorn 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 cooperation between the guide port 52, the spring 54, the mesh plate 55 and the second thorn 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 thorn needle 56 will vibrate up and down accordingly. In the process, the second thorn needle 56 can further puncture the passing air bubbles to achieve a double rupture effect, ensuring that the oxygen in the air bubbles is released upward. During the ascension process, oxygen is fully released, reducing oxygen escape and improving oxygen utilization. Through the cooperation between the vertical shaft 61, the fiber ball assembly 62, the arc blade 64, the arc 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 arc scraper 65 and the elastic scraper strip 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, 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 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, and the specific process includes the following steps:

[0061] Step 1: The sewage 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, and then the sewage flows upward through the lower baffle mechanism 5 to immerse the fiber ball assembly 62. During the process, an external blower is used to send air into the aeration mechanism 4, and the aeration mechanism 4 aerates the sewage to generate a large number of fine air bubbles;

[0062] Step 2: During the rising process of air bubbles, aeration mechanism 4 timely punctures some of the passing air bubbles. During the process, since aerobic bacteria will produce sludge when degrading organic matter in sewage, filter screen cover 461 can prevent sludge from clogging the micropores on the surface of microporous aeration disk 44, thereby ensuring the normal aeration effect of microporous aeration disk 44. Since sewage flows upward, it can impact impeller 463 with the flow of water, so that impeller 463 drives arc-shaped brush 464 to rotate. The rotating arc-shaped brush 464 can timely scrape the surface of filter screen cover 461, thereby avoiding the accumulation of sludge on the surface of filter screen cover 461, so that the air bubbles generated by aeration can pass through filter screen cover 461 normally. Moreover, under the action of first puncture needle 465, during the process of air bubbles passing through filter screen cover 461, first puncture needle 465 can be used to clean the surface of filter screen cover 461. 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 unpunctured air bubbles continue to rise. In the process of passing through the lower baffle mechanism 5, the air bubbles are further punctured by the lower baffle mechanism 5. In the 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 puncture needle 56 will vibrate up and down accordingly. In the process, the second puncture needle 56 can further puncture the passing air bubbles to achieve 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 assemblies 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 assembly 62 and form a dense biofilm, and 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, and the purified water is finally discharged through the liquid outlet pipe 3, wherein the sludge generated in the process of aerobic bacteria degrading the organic matter is adsorbed on the surface of the fiber ball assembly 62, and when the sludge on the surface of the fiber ball assembly 62 accumulates to a certain extent, the fiber ball assembly 62 is pushed and scraped and cleaned by using the arc scraper 65 and the elastic scraper strip 66, and during the process, the electromagnetic valves on the sewage inlet pipe 2 and the liquid outlet pipe 3 are first closed, and the electromagnetic valves on the water injection pipe 14 and the liquid discharge pipe 15 are opened, and 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, so that the arc blade 64 and the sleeve 63 on each attachment rod mechanism 6 are rotated, 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 to complete the cleaning of the fiber ball assembly 62.
