Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment for beverage production, and particularly to a mobile activated sludge incubator. Background Art

[0002] In the modern food industry, especially in large food factories involved in the production of nata de coco cans, beverages, etc., a large amount of sewage and sludge will inevitably be generated during the production process. These sludges are rich in organic pollutants. If not properly treated, they will not only cause serious environmental pollution but also waste the available resources therein. Therefore, efficient sludge treatment technology has become one of the key links in the sustainable development of food factories. As a common biological treatment technology, the activated sludge method decomposes organic pollutants by using microorganisms in the sludge, and has advantages such as good treatment effect and relatively low cost, and has been widely used in the field of sludge treatment;

[0003] At present, there are various devices for culturing and treating activated sludge on the market. Among them, the mobile activated sludge incubator has received extensive attention due to its characteristics such as being easy to transport and being able to be used flexibly in different sites. Existing mobile activated sludge incubators usually have basic functions such as aeration and stirring. Aeration provides oxygen for the microorganisms in the sludge to promote the growth of microorganisms and the decomposition of organic pollutants; stirring can make the sludge fully contact with the gas, improve the oxygen transfer efficiency, and prevent sludge deposition.

[0004] However, there are still some defects that need to be urgently solved in the existing mobile activated sludge incubators:

[0005] In terms of aeration: Existing aeration devices often have difficulty ensuring that each filter hole remains unobstructed, and local filter hole blockages are likely to occur, resulting in uneven aeration. This will not only affect the living environment of microorganisms, reduce their decomposition and conversion efficiency of organic pollutants, but also affect the quality of sludge treatment. In addition, the gas pressure and speed of some aeration devices are insufficient, making it difficult to penetrate deep into the sludge layer, so that the oxygen dissolution in the sludge is insufficient, restricting the activity of microorganisms and affecting the decomposition speed of organic pollutants. Moreover, some aeration devices lack a stable gas supply mechanism. When the gas is insufficient, the aeration intensity will decrease, resulting in unstable sludge treatment effects and even possible impact and damage to the equipment;

[0006] In terms of agitation: The existing agitation devices have an unsatisfactory agitation effect on the sludge, making it difficult to form a uniform suspension state of the sludge in the box. This will result in insufficient contact area between the sludge and the gas, and the gas cannot be fully dissolved in the sludge, reducing the oxygen transfer efficiency. At the same time, uneven agitation will also cause uneven distribution of microorganisms and organic substances in the sludge, which is not conducive to the uptake and decomposition of organic pollutants by microorganisms. In addition, for the sludge that is prone to form a layered structure during the static process, the existing agitation devices cannot effectively break this structure, hindering the diffusion of gas and the activities of microorganisms, resulting in insufficient treatment of local sludge;

[0007] In terms of sludge dispersion: The existing equipment has a poor dispersion effect on the sludge, and the bonding structure between sludge particles is difficult to be destroyed, resulting in poor sludge fluidity. This will not only increase the resistance of the sludge in the subsequent treatment process and reduce the treatment efficiency, but also cause bubbles to concentrate on the surface of the sludge layer and be difficult to penetrate into the interior of the sludge, resulting in low oxygen transfer efficiency, affecting the growth and reproduction of microorganisms, and further affecting the smooth progress of the sludge treatment process. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the present invention provides a mobile activated sludge culture box, which solves the technical problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: A mobile activated sludge culture box includes a box body. A plurality of groups of L-shaped fixing plates are fixedly connected to the inner wall of the box body.

Four movable rods are rotatably arranged at positions deviating from the center of the circle between the first disk and the second disk. The other end of the movable rod is rotatably connected with a moving rod that is horizontally slidably installed in the inner cavity of the air guide pipe, and the other end of the moving rod is fixedly connected with the cleaning rod.

[0012] As a further preference of this technical solution, an installation shaft is arranged at the bottom end of the second disk. A second rotating disk is arranged at the bottom end of the installation shaft. A positioning shaft is fixedly connected to the center of the second rotating disk. The bottom end of the positioning shaft penetrates through the cylinder and is fixedly connected with a fan blade.

[0013] As a further preferred embodiment of the present technical solution, a first gear is provided on the outer wall of the mounting shaft, and the outer wall of the first gear is meshingly connected with an inner gear ring fixedly mounted on the inner cavity of the cylinder.

[0014] As a further optimization of the present technical solution, four groups of guide rods are fixedly connected to the upper end of the inner cavity of the cylinder, a pressure plate is slidably connected to the guide rods, the pressure plate is sealingly and slidably connected to the inner cavity of the cylinder, and the pressure plate is threadedly connected to the connecting rod.

[0015] As a further preferred embodiment of the present technical solution, a sliding groove is provided on the side wall of the L-shaped fixing plate, and a rack is fixedly connected to the L-shaped fixing plate.

[0016] As a further preferred embodiment of the present technical solution, the auxiliary component includes a cross bar fixedly mounted on the inner wall of the box body, a sliding frame is laterally slidably connected to the top of the cross bar, rotating rods are rotatably connected on both sides of the bottom end of the sliding frame, a fixed ring, a second gear, and a sliding seat are fixedly connected to the rotating rod in sequence, fixed plates are fixedly connected on both sides of the sliding frame, and the fixed plates are sleeved on the rotating rod, a reciprocating groove is opened on the surface of the fixed plate, the sliding seat is slidably mounted in the sliding groove, and the second gear is meshingly connected to the rack.

[0017] As a further preferred embodiment of the present technical solution, a driving motor is fixedly mounted on the slide frame, an output end of the driving motor is fixedly connected to a first bevel gear, and both sides of the first bevel gear are meshingly connected to second bevel gears fixedly mounted on the rotating rod.

[0018] As a further preferred embodiment of the present technical solution, a connecting frame is fixedly connected to the outer wall of the fixed ring, a row of toggle rods are arranged on the inner side of the connecting frame, a swing frame is horizontally slidably connected to the connecting frame, a row of knocking rods are arranged on the inner side of the swing frame, and each knocking rod is located between adjacent toggle rods, and a guide rod with one end slidably installed in the reciprocating groove is fixedly connected to one side of the swing frame.

[0019] Compared with the prior art, it has the following beneficial effects:

[0020] By turning on the motor to drive the linkage of a series of components such as the connecting rod and the movable rod, the cleaning rod can move back and forth in the air duct. The design of the cleaning rod can be accurately inserted into the filter holes of the filter baffle to effectively clean the impurities in the filter holes. This precise cleaning method can ensure that each filter hole can remain unobstructed, avoiding the problem of uneven aeration caused by local blockage of the filter holes; by cleaning the filter baffle in real time, the continuity of aeration is guaranteed. Continuous aeration can keep the microorganisms in the sludge in a good living environment at all times, which is beneficial to the decomposition and transformation of organic pollutants by microorganisms, and improves the efficiency and quality of sludge treatment.

[0021] When the second disc rotates circumferentially, through the transmission of components such as the mounting shaft, the first gear, and the internal gear ring, the second rotating disc, the positioning shaft, and the fan blades are driven to rotate. The rotation of the fan blades can fully stir the sludge, causing the sludge to form a uniform suspension state in the box. In this state, the contact area between the sludge and the gas is greatly increased, and the gas can be more fully dissolved in the sludge, improving the oxygen transfer efficiency. At the same time, the stirring can also make the microorganisms and organic substances in the sludge more evenly distributed, which is beneficial to the uptake and decomposition of organic pollutants by microorganisms. During the static process, the sludge often forms a layered structure, which will hinder the diffusion of gas and the activities of microorganisms. The stirring effect of the fan blades can break the layered structure of the sludge, causing the sludge particles to collide and mix with each other, increasing the fluidity of the sludge. The increased fluidity helps the gas to penetrate and diffuse in the sludge, making the aeration effect more uniform. In addition, the stirring can also prevent the sludge from depositing at the bottom of the box, avoiding the occurrence of insufficient treatment of local sludge.

[0022] The rotation of the connecting rod drives the pressure plate to move up and down. When the pressure plate moves downward, the gas in the cylinder will be pressurized. The pressurized gas has a higher pressure and speed when discharged, and can penetrate deeper into the sludge layer, making the oxygen more fully dissolved in the sludge. This high-intensity aeration can improve the activity of microorganisms and accelerate the decomposition and transformation of organic pollutants. At the same time, the pressurized aeration can also expand the influence range of aeration, covering every corner of the box with the aeration effect, improving the uniformity and effectiveness of aeration. When the pressure plate moves upward, gas is supplemented by the continuous delivery of gas through the connecting pipe and the gas transmission pipe. This gas supplementation mechanism can ensure that there is always enough gas supply in the cylinder, avoiding the decrease in aeration intensity caused by insufficient gas. A stable gas supply is the basis for maintaining the normal progress of the aeration process, ensuring the stability and reliability of the sludge treatment effect. In addition, the continuous gas supplementation can also adjust the pressure in the box, making the aeration process more stable and reducing the impact and damage to the equipment.

[0023] The sludge is stirred and dispersed by the connecting frame and the toggle rod. At the same time, the reciprocating knocking vibration of the knocking rod on the toggle rod further destroys the bonding structure between the sludge particles. This dual effect weakens the mutual force between the sludge particles, and the sludge gradually disperses from the viscous block into smaller particles, resulting in a significant improvement in fluidity. The improved fluidity enables the sludge to flow more smoothly during the subsequent treatment process, reducing the resistance during the treatment process and improving the treatment efficiency. In traditional sludge treatment, bubbles often concentrate on the surface of the sludge layer and are difficult to penetrate into the interior of the sludge, resulting in low oxygen transfer efficiency. After being treated by this device, the improved fluidity of the sludge allows the bubbles to be more evenly dispersed in the sludge. The bubbles are no longer limited to the surface but can penetrate into every corner of the sludge, making more sufficient contact with the microorganisms and organic substances in the sludge. This sufficient contact greatly improves the oxygen transfer efficiency, enabling the microorganisms to obtain more oxygen to maintain their life activities and carry out metabolism. The sufficient oxygen supply provides favorable conditions for the growth and reproduction of microorganisms, thus promoting the smooth progress of the sludge treatment process.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. 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 work are within the scope of protection of the present invention.

[0034] Embodiment 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a mobile activated sludge culture box, comprising a box body 1, a plurality of groups of L-shaped fixing plates 2 are fixedly connected to the inner wall of the box body 1, an auxiliary component 4 is arranged between each group of L-shaped fixing plates 2 to enhance the stability of the structure, and a row of cylinders 3 is arranged between each adjacent group of L-shaped fixing plates 2, and these cylinders 3 are arranged in order to ensure uniform force on the entire box body 1 structure;

[0035] A connecting pipe 31 is fixedly installed at the outer end of the cylinder 3, and an air pipe 32 is connected to both sides of the connecting pipe 31. The other end of the air pipe 32 is connected to the inner cavity of the cylinder 3 to ensure that the gas can smoothly enter the cylinder 3 from the connecting pipe 31 through the air pipe 32. An air guide pipe 33 is connected to the bottom of the cylinder 3. A filter baffle 34 is provided at the other end of the outer wall of the air guide pipe 33. The function of the filter baffle 34 is to block the sludge and prevent it from entering the air guide pipe 33 to affect the normal flow of gas and the aeration effect.

[0036] In order to further ensure that the through holes of the filter baffle 34 are not blocked by sludge, a cleaning rod 312 for cleaning the through holes of the filter baffle 34 is arranged in the air guide pipe 33. The connecting pipe 31 is connected to an external pump body. When gas is transported to the connecting pipe 31 and the air delivery pipe 32, and the gas is discharged through the air guide pipe 33 for aeration treatment, the filter baffle 34 blocks the sludge, ensuring the smoothness of the aeration process;

[0037] A motor 35 is fixedly installed at the top of the connecting pipe 31. The output end of the motor 35 is fixedly connected to a connecting rod 36. The bottom end of the connecting rod 36 is fixedly connected to a first rotating disk 37. A first disk 38 is arranged at a position deviating from the center of the bottom of the first rotating disk 37. A second disk 39 is arranged below the first disk 38. Four groups of movable rods 310 are rotatably arranged at a position deviating from the center between the first disk 38 and the second disk 39. The other end of the movable rod 310 is rotatably connected to a moving rod 311 that is horizontally slidably installed in the inner cavity of the air guide pipe 33. The other end of the moving rod 311 is fixedly connected to the cleaning rod 312. By starting the motor 35 to drive the connecting rod 36 and the movable rod 310 to rotate, the first rotating disk 37 and the first disk 38 rotate. During the rotation process, the first disk 38 cooperates with the second disk 39, causing the four groups of movable rods 310 to move reciprocally. Furthermore, the movable rod 311 and the cleaning rod 312 are driven by the movable rod 310 to move reciprocally in the air guide pipe 33. This reciprocating cleaning rod 312 can be inserted into the filter holes of the filter baffle 34 to clean the filter holes of the filter baffle 34, preventing the sludge from blocking the filter baffle 34 during the aeration process and affecting the aeration effect, thus ensuring the efficient and stable operation of the entire aeration system;

[0038] At the bottom end of the second disk 39, an installation shaft 313 is specially designed. The bottom end of this shaft is further connected to a second rotating disk 314. In order to ensure the stable rotation of the second rotating disk 314, a positioning shaft 315 is fixedly connected to its center. The bottom end of the positioning shaft 315 penetrates through the cylinder body 3 and is firmly fixedly connected to the fan blade 316. In addition, a first gear 317 is arranged on the outer wall of the installation shaft 313. The first gear 317 is meshed and connected with an internal gear ring 318 fixedly installed in the inner cavity of the cylinder body 2. When the second disk 39 rotates circumferentially, this structural design enables the second rotating disk 314, the positioning shaft 315, and the fan blade 316 to rotate in coordination. Such a rotation mechanism enables the fan blade 316 to effectively stir the sludge, making the stirred sludge easier to undergo subsequent aeration treatment and improving the treatment efficiency;

[0039] At the upper end of the inner cavity of the cylinder body 3, four guide rods 319 are fixedly connected. A pressure plate 320 is slidably connected to these guide rods 319. The pressure plate 320 realizes a sealed sliding connection with the inner cavity of the cylinder body 3, ensuring the airtightness during the operation. The pressure plate 320 is threadedly connected to the connecting rod 36. A reciprocating thread is provided on the connecting rod 36. This design enables the connecting rod 36 to drive the pressure plate 320 to move up and down when rotating. The guide rods 319 play a guiding role during the up and down movement of the pressure plate 320, ensuring that the pressure plate 320 can move in the vertical direction. When the pressure plate 320 moves downward, it pressurizes the gas in the cylinder body 3, thereby further increasing the aeration intensity. When the pressure plate 320 moves upward, through the continuous delivery of gas through the connecting pipe 31 and the air delivery pipe 32, gas is replenished, ensuring the continuity and stability of the aeration process.

[0040] In the embodiment of the present invention, the connection between the connecting pipe 31 and the external pump body is set by delivering gas to the connecting pipe 31 and the air delivery pipe 32, and the gas is then discharged through the air guide pipe 33 for aeration treatment. By starting the motor 35 to drive the rotation of the connecting rod 36 and the movable rod 310, the first rotating disk 37 and the first disk 38 rotate. When the first disk 38 rotates, it cooperates with the second disk 39, causing the four movable rods 310 to move reciprocally. Furthermore, the movable rod 310 drives the moving rod 311 and the cleaning rod 312 to move reciprocally within the air guide pipe 33. The reciprocating cleaning rod 312 can be inserted into the filter holes of the filter baffle 34 to clean the filter holes of the filter baffle 34, preventing the sludge from blocking the filter baffle 34 during the aeration process and thus affecting the aeration effect. When the second disk 39 rotates in a circle, it can drive the second rotating disk 314, the positioning shaft 315, and the fan blade 316 to rotate in cooperation with the mounting shaft 313, the first gear 317, and the internal gear ring 318, enabling the fan blade 316 to stir the sludge. After stirring, the sludge is more easily subjected to aeration treatment;

[0041] When the connecting rod 36 rotates, it can drive the pressure plate 320 to move up and down. At the same time, the guide rods 319 play a guiding role for the pressure plate 320 moving up and down, enabling the pressure plate 320 to move in the vertical direction. When the pressure plate 320 moves downward, it can pressurize the gas in the cylinder body 3, further increasing the aeration intensity. When the pressure plate 320 moves upward, gas is continuously delivered through the connecting pipe 31 and the air delivery pipe 32 for gas replenishment;

[0042] During the sludge aeration treatment process, impurities in the sludge can easily adhere to the filter holes of the filter baffle 34 along with the gas flow, resulting in the blockage of the filter holes, which in turn affects the normal discharge of gas and the aeration effect. The device drives the linkage of a series of components such as the connecting rod 36 and the movable rod 310 by turning on the motor 35, enabling the cleaning rod 312 to reciprocate within the air duct 33. The design of the cleaning rod 312 can accurately insert into the filter holes of the filter baffle 34 to effectively clean the impurities in the filter holes. This precise cleaning method can ensure that each filter hole remains unobstructed, avoiding the problem of uneven aeration caused by local filter hole blockage. The normal operation of the filter baffle 34 is the key to ensuring continuous aeration. If the filter holes are blocked by sludge and the gas cannot pass through smoothly, it will lead to the interruption of aeration or insufficient aeration volume. The cleaning function of the device can clean the filter baffle 34 in real time, ensuring the continuity of aeration. Continuous aeration can keep the microorganisms in the sludge in a good living environment all the time, which is beneficial to the decomposition and transformation of organic pollutants by microorganisms, improving the efficiency and quality of sludge treatment;

[0043] When the second disc 39 rotates in a circle, through the transmission of components such as the mounting shaft 313, the first gear 317, and the internal gear ring 318, it drives the second rotating disc 314, the positioning shaft 315, and the fan blade 316 to rotate. The rotation of the fan blade 316 can fully stir the sludge, making the sludge form a uniform suspension state in the box body 1. In this state, the contact area between the sludge and the gas is greatly increased, and the gas can be more fully dissolved in the sludge, improving the oxygen transfer efficiency. At the same time, the stirring can also make the microorganisms and organic substances in the sludge more evenly distributed, which is beneficial to the uptake and decomposition of organic pollutants by microorganisms. The sludge often forms a layered structure during the static process, and this structure will hinder the diffusion of gas and the activities of microorganisms. The stirring effect of the fan blade 316 can break the layered structure of the sludge, causing the sludge particles to collide and mix with each other, increasing the fluidity of the sludge. The increase in fluidity helps the gas to penetrate and diffuse in the sludge, making the aeration effect more uniform. In addition, the stirring can prevent the sludge from depositing at the bottom of the box body 1, avoiding the occurrence of insufficient treatment of local sludge;

[0044] The connecting rod 36 rotates to drive the pressure plate 320 to move up and down. When the pressure plate 320 moves downward, the gas in the cylinder 3 will be pressurized. The pressurized gas has a higher pressure and speed when discharged, and can penetrate the sludge layer more deeply, so that oxygen is more fully dissolved in the sludge. This high-intensity aeration can improve the activity of microorganisms and accelerate the decomposition and transformation of organic pollutants. At the same time, pressurized aeration can also expand the influence range of aeration, so that the aeration effect covers every corner of the box 1, and improves the uniformity and effectiveness of aeration. When the pressure plate 320 moves upward, the gas is continuously transported by the connecting pipe 31 and the gas pipe 32 to supplement the gas. This gas supplement mechanism can ensure that there is always enough gas supply in the cylinder 3, avoiding the decrease in aeration intensity due to insufficient gas. Stable gas supply is the basis for maintaining the normal aeration process, which can ensure the stability and reliability of the sludge treatment effect. In addition, the continuous replenishment of gas can also adjust the pressure in the box 1, making the aeration process more stable and reducing the impact and damage to the equipment.

[0045] Embodiment 2: Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, on the basis of the first embodiment, a sliding groove 21 is provided on the side wall of the L-shaped fixing plate 2, and a rack 22 is fixedly connected to the L-shaped fixing plate 2;

[0046] The auxiliary component 4 includes a cross bar 41 fixedly mounted on the inner wall of the box body 1, a slide frame 42 is slidably connected to the top of the cross bar 41, and rotating rods 46 are rotatably connected to the two sides of the bottom of the slide frame 42, and a fixing ring 411, a second gear 47, and a slide seat 48 are fixedly connected to the rotating rod 46 in sequence, and a fixed plate 49 is fixedly connected to the two sides of the slide frame 42, and the fixed plate 49 is sleeved on the rotating rod 46, and a reciprocating groove 410 is opened on the surface of the fixed plate 49, and the slide seat 48 is slidably installed in the slide groove 21, and the second gear 47 is meshed with the rack 22;

[0047] A driving motor 43 is fixedly mounted on the slide frame 42, and a first bevel gear 44 is fixedly connected to the output end of the driving motor 43. Second bevel gears 45 fixedly mounted on a rotating rod 46 are meshedly connected to both sides of the first bevel gear 44.

[0048] A connecting frame 412 is fixedly connected to the outer wall of the fixed ring 411, a row of toggle rods 413 are arranged on the inner side of the connecting frame 412, a swing frame 414 is horizontally slidably connected to the connecting frame 412, a row of knocking rods 415 are arranged on the inner side of the swing frame 414, and each knocking rod 415 is located between adjacent toggle rods 413, and a guide rod 416 with one end slidably installed in the reciprocating groove 410 is fixedly connected to one side of the swing frame 414.

[0049] In the embodiment of the present invention, by turning on the driving motor 43, the first bevel gear 44 is driven to rotate forward and reversely, and the first bevel gear 44 drives the second bevel gear 45 meshing on both sides to rotate, thereby driving the rotating rod 46, the second gear 47, the slide seat 48, the fixed ring 411, the connecting frame 412, the toggle rod 413, the swing frame 414, and the guide rod 416 to rotate synchronously, so that the rotating connecting frame 412 and the toggle rod 413 are toggled to disperse the sludge. At the same time, the guide rod 416, under the action of the reciprocating groove 410 of the fixed plate 49, drives the swing frame 414 and the knocking rod 415 located on the connecting frame 412 to move back and forth laterally, so that the reciprocating knocking rod 415 reciprocates and vibrates the toggle rod 413. Under the vibration of the toggle rod 413, the sludge gradually becomes The loosening of the sludge particles weakens the bonding force between the sludge particles, which significantly improves the fluidity of the sludge. The bubbles can be more evenly dispersed in the sludge. The bubbles are no longer concentrated on the surface of the sludge layer, but can penetrate into the interior of the sludge and make more adequate contact with the microorganisms and organic matter in the sludge. This greatly improves the oxygen transfer efficiency, allowing the microorganisms to obtain more oxygen for metabolic activities, thereby accelerating the decomposition and transformation of organic pollutants in the sludge. At the same time, when the vibrating toggle rod 413 moves in the sludge, it will also produce a certain stirring effect on the sludge. This stirring helps to mix the different components in the sludge, so that the nutrients and microorganisms can be more evenly distributed, avoiding the occurrence of local nutrient excess or insufficient microbial activity.

[0050] Due to the meshing action of the second gear 47 and the rack 22, the rotating rod 46, the fixing ring (411), the connecting frame 412, the toggle rod 413, the sliding frame 42, and the driving motor 43 on the crossbar 41 can be driven to move back and forth horizontally, so that the connecting frame 412 and the toggle rod 413 can break up the sludge at different positions in the box body 1;

[0051] The connecting frame 412 and the toggle rod 413 stir and break up the sludge. At the same time, the reciprocating knocking vibration of the knocking rod 415 on the toggle rod 413 further destroys the bonding structure between the sludge particles. This dual action weakens the interaction force between the sludge particles, and the sludge gradually disperses from the viscous block into smaller particles, resulting in a significant improvement in fluidity. The improved fluidity enables the sludge to flow more smoothly in the subsequent treatment process, reduces the resistance during the treatment process, and improves the treatment efficiency. In traditional sludge treatment, bubbles often concentrate on the surface of the sludge layer and are difficult to penetrate deep into the sludge, resulting in low oxygen transfer efficiency. After being treated by this device, the improved fluidity of the sludge allows the bubbles to be more evenly dispersed in the sludge. The bubbles are no longer limited to the surface but can penetrate into every corner of the sludge, making more sufficient contact with the microorganisms and organic substances in the sludge. This sufficient contact greatly improves the oxygen transfer efficiency, enabling the microorganisms to obtain more oxygen to maintain their life activities and carry out metabolism. The sufficient oxygen supply provides favorable conditions for the growth and reproduction of the microorganisms, thus promoting the smooth progress of the sludge treatment process.
