Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a wastewater treatment device and method for polyglutamic acid fermentation liquid. Background Art

[0002] Polyglutamic acid (γ-polyglutamic acid, poly-r-glutamic acid, γ-PGA) is a natural polymer synthesized by microorganisms, which is composed of D-glutamic acid and L-glutamic acid monomers connected by γ-amide bonds in different proportions. In 1937, Ivanovics and Bruckner first isolated and extracted the extracellular polypeptide γ-PGA from the capsule of Bacillus anthracis. Later, it was found that γ-PGA can also be secreted by Bacillus subtilis into the growth medium as a fermentation product. Polyglutamic acid is a new green and environmentally friendly material. It is widely used in food, agriculture, cosmetics, biomedicine and other industries because of its water solubility, plasticity, high adsorption and biodegradability. Polyglutamic acid produces wastewater during the fermentation process. Most of the existing treatment methods are: in the aeration stage, the wastewater is mixed with a reagent containing microorganisms, and oxygen is provided to the mixed liquid to promote the growth of microorganisms and the degradation of organic matter. Then, the mixed liquid enters the sedimentation tank, where the microorganisms and suspended solids settle to the bottom of the tank by gravity. This process effectively removes organic matter and suspended matter in the wastewater.

[0003] However, in the prior art, when treating the wastewater of polyglutamic acid fermentation liquid, most of the methods are to allow microorganisms and suspended solids to settle to the bottom of the pool due to gravity through sedimentation. Although the organic matter and suspended matter in the wastewater are removed, only the upper clean water can be discharged during the drainage process. The lower clean water will bring out the sediment when draining, so it is generally not discharged, but discharged together with the sediment. The joint discharge of sediment and clean water will make the treatment of solid impurities more complicated and difficult, and additional subsequent treatment steps may be required to separate and treat these sediments, thereby increasing the burden and operating costs of the overall treatment system. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0035] Reference Figures 1 to 3 In an embodiment of the present invention, a wastewater treatment device for polyglutamic acid fermentation liquid includes: a treatment barrel 1 for containing wastewater, a drainage barrel 2 for collecting clean water, and a support frame 3, wherein the bottom end of the treatment barrel 1 is fixedly connected to the drainage barrel 2 and communicated with each other, the outer side of the drainage barrel 2 is fixedly connected to the support frame 3, the bottom end of the treatment barrel 1 is provided with a mounting groove 11, the mounting groove 11 is fan-shaped, and the mounting groove 11 is provided with five groups, which are evenly provided at the bottom end of the treatment barrel 1, and the mounting groove 11 is provided with a filter hole 12 for filtering the wastewater in the treatment barrel 1, and the filter hole 12 is provided with a plurality of holes and the aperture thereof can be set according to the demand. , a plurality of filter holes 12 are evenly distributed in the installation groove 11, a baffle 13 is slidably arranged in the installation groove 11, one end of the baffle 13 is fixedly connected to a spring 14, one end of the spring 14 is fixedly connected to the inner wall of the installation groove 11, each group of baffles 13 is fixedly connected to two groups of springs 14, an aeration device 4 is arranged in the treatment barrel 1 to increase the oxygen content of the wastewater in the treatment barrel 1 and promote the reaction of the wastewater with the active agent containing microorganisms, and an activation member 5 for adjusting the position of the baffle 13 is arranged on the treatment barrel 1. When the activation member 5 is in the initial state, the baffle 13 is restricted so that the baffle 13 blocks the filter hole 12;

[0036] When the aeration device 4 is in operation, air is continuously introduced into the interior of the treatment barrel 1. At this time, the aeration device 4 is magnetically connected to the activation member 5 under the thrust of the air. As the air is discharged into the wastewater, the thrust gradually decreases, causing the aeration device 4 to drive the activation member 5 to move, thereby releasing the restriction of the activation member 5 on the baffle 13, and causing the baffle 13 to be misaligned with the filter hole 12 under the action of the spring 14.

[0037] Reference Figures 4 to 7 The aeration device 4 includes an air inlet pipe 41 fixedly connected to the bottom end of the processing barrel 1, the bottom end of the air inlet pipe 41 passes through the processing barrel 1, a guide block 411 is fixedly connected to the outside of the air inlet pipe 41, a lifting cylinder 42 is sleeved on the outside of the air inlet pipe 41, the lifting cylinder 42 is meshed and connected with the guide block 411, a stirring rod 43 is connected through the side end of the lifting cylinder 42, and a plurality of stirring rods 43 are arranged and evenly distributed on the side end of the lifting cylinder 42, a rotating ring 44 is rotatably connected to the bottom end of the processing barrel 1, a spring 2 45 is fixedly connected to the top of the rotating ring 44, one end of the spring 2 45 is fixedly connected to the bottom end of the lifting cylinder 42, five groups of springs 2 45 are arranged and evenly distributed on the top of the rotating ring 44, a ball 412 is embedded in the guide block 411, and the ball 412 is rotatably connected to the guide block 411, and a plurality of groups of balls 412 are arranged and evenly distributed on the joints between the guide block 411 and the lifting cylinder 42. On the contact surface, the friction between the guide block 411 and the lifting cylinder 42 is reduced. An exhaust hole 413 is opened through the side end of the lifting cylinder 42. The exhaust hole 413 is arranged in multiple groups and is spirally designed and evenly distributed on the side end of the lifting cylinder 42. An exhaust hole 431 is opened through the stirring rod 43. The exhaust hole 431 is arranged in multiple groups and is evenly distributed on the side end of the lifting cylinder 42. When air enters the air inlet pipe 41 from bottom to top, it will push the lifting cylinder 42 to rotate and rise along the guide block 411, and drive the stirring rod 43 to rotate, so as to mix the wastewater with the agent rich in microorganisms. During the rising process, the air will enter the treatment barrel 1 through the exhaust hole 413 and the exhaust hole 431, so as to promote the growth of microorganisms and the degradation of organic matter. In this process, the amount of air entering the air inlet pipe 41 is greater than the amount of air discharged from the exhaust hole 413 and the exhaust hole 431.

[0038] The above scheme is adopted: a large amount of air is injected into the treatment barrel 1 through the air inlet pipe 41. As the air increases, the pressure inside the lifting cylinder 42 gradually increases, thereby pushing the lifting cylinder 42 upward. At this time, under the cooperation of the guide block 411 and the ball 412, the lifting cylinder 42 spirally rises along the outer surface of the air inlet pipe 41, thereby driving the stirring rod 43 to rotate synchronously with the movement of the lifting cylinder 42 in the vertical direction, stirring the wastewater in the treatment barrel 1. At the same time, air enters the treatment barrel 1 through the exhaust hole 1 413 and the exhaust hole 2 431, providing sufficient oxygen. Through continuous air supply and stirring, the aeration device 4 promotes full contact between the wastewater and the agent, enhances the efficiency of wastewater treatment, can effectively remove organic matter and suspended matter in the wastewater, and improve the treated water quality. The aeration device 4 combines air thrust, springs and magnetic components, so that the device can automatically adjust its position and operating state when the air pressure changes. This automatic control method improves the stability of the system and the convenience of operation.

[0039] Reference Figure 3 and Figure 6The activating member 5 includes a connecting block 51 fixedly connected to the outside of the processing barrel 1. Five groups of connecting blocks 51 are arranged and evenly distributed on the outside of the processing barrel 1. A linkage plate 52 is hinged at one end of the connecting block 51. The linkage plate 52 is T-shaped. A spring three 53 is fixedly connected to one end of the linkage plate 52. One end of the spring three 53 is fixedly connected to the outside of the processing barrel 1. A pull rope 55 is fixedly connected to one side of the linkage plate 52. One end of the pull rope 55 is fixedly connected to a connecting column 56. A rotating disk 57 is fixedly connected to the bottom end of the connecting column 56. A magnetic disk 58 is rotatably connected to the bottom end of the rotating disk 57. The magnetic disk 58 is connected to the The lifting cylinder 42 is embedded with magnets on the opposite sides, and the magnetic poles of the two magnets are opposite, so that when the distance between the magnetic disk 58 and the lifting cylinder 42 is close, the two magnets can generate magnetic force to attract each other. A magnetic block 1 54 is embedded on one side of the linkage plate 52, and a magnetic block 2 131 is embedded on one side of the baffle 13. The corresponding surfaces of the magnetic block 1 54 and the magnetic block 2 131 are of the same polarity. When the lifting cylinder 42 rises to the limit position, the lifting cylinder 42 is attracted to the magnetic disk 58 through the magnet embedded on the top. Then, as the air in the intake pipe 41 decreases, the lifting cylinder 42 is attracted to the magnetic disk 58 under the action of the spring 2 45. The magnetic disk 58 moves downward and drives the magnetic disk 58 to move downward. Under the action of the pull rope 55, the linkage plate 52 is pulled to rotate around the connection block 51, so that the magnetic block 1 54 is misaligned with the magnetic block 2 131, and the restriction of the baffle 13 is released, so that the spring 14 pushes the baffle 13 to move outward, and the filter hole 12 is exposed. With the movement of the lifting cylinder 42, and due to the length restriction of the pull rope 55 and the spring three 53, the magnetic disk 58 is separated from the lifting cylinder 42. At this time, under the action of the spring three 53, the linkage plate 52 is reset, and the magnetic block 1 54 is aligned with the magnetic block 2 131. Under the repulsive force of the second spring 131, the baffle 13 is moved above the filter hole 12, wherein the repulsive force between the magnetic block 1 54 and the second magnetic block 131 is greater than the elastic force generated by the spring 1 14, the suction force when the magnetic disk 58 is not in contact with the magnet embedded in the top of the lifting cylinder 42 is less than the elastic force generated by the spring three 53, the suction force when the magnetic disk 58 is in contact with the magnet embedded in the top of the lifting cylinder 42 is greater than the elastic force generated by the spring three 53, the elastic force generated by the spring two 45 is greater than the suction force of the magnetic disk 58 and the magnet embedded in the top of the lifting cylinder 42, and the elastic force generated by the spring two 45 is greater than the elastic force generated by the spring three 53.

[0040] The above scheme is adopted: through the linkage plate 52, spring three 53, pull rope 55 and magnetic block one 54, magnetic block two 131 and other structures, the position of the baffle 13 can be accurately controlled. By adjusting the position of the baffle 13, the filter hole 12 can be effectively blocked or exposed, allowing the wastewater to flow into the drainage bucket 2 through the filter hole 12. This control mechanism can ensure that solid impurities and suspended matter in the wastewater treatment process can be effectively removed, thereby improving the treatment effect, and by moving the baffle 13, the solid impurities above the filter hole 12 can be scraped off, improving the patency of the filter hole 12, thereby further optimizing the efficiency of wastewater treatment.

[0041] Reference Figure 1 to Figure 2 A sedimentation collection box 6 for storing solid impurities is fixedly connected to the outside of the processing barrel 1, and a connecting pipe 7 is connected to the bottom end of the air inlet pipe 41. One end of the connecting pipe 7 passes through the drainage barrel 2 and the sedimentation collection box 6. An air pump 8 is fixedly connected to the support frame 3, and one end of the connecting pipe 7 is connected to the output end of the air pump 8. The rising height of the lifting cylinder 42 can be freely controlled by the air pump 8 and the connecting pipe 7.

[0042] The above scheme is adopted: the air pump 8 can remotely control the movement of the lifting cylinder 42 through the connecting pipe 7, which simplifies the operation process. The wastewater treatment process can be accurately controlled by adjusting the setting of the air pump 8, which reduces manual intervention and improves the level of automation.

[0043] Reference Figures 8 to 9 A discharge hole 15 is provided through the side end of the treatment barrel 1, and five groups of discharge holes 15 are arranged and are evenly arranged at the side end of the treatment barrel 1. A feed trough 61 is provided through one end of the sedimentation collection box 6. Five groups of feed troughs 61 are arranged and are evenly arranged at one end of the sedimentation collection box 6. Each group of discharge holes 15 is connected with a group of feed troughs 61. A spring four 62 is fixedly connected to the inner end of the sedimentation collection box 6. A baffle plate 63 is fixedly connected to one end of the spring four 62. Five groups of baffle plates 63 are arranged. Each group of baffle plates 63 is arranged on the inner side of a group of feed troughs 61 and abuts against the inner wall of the sedimentation collection box 6. Multiple groups of filter holes are arranged on the baffle plate 63 so that when water flows through, solid impurities are For filtering, a plurality of spring fours 62 are arranged on one side of each group of baffle plates 63, the elastic force generated by spring four 62 is smaller than the elastic force generated by spring one 14, a discharge groove 64 is provided through the bottom of the sedimentation collection box 6, and four groups of discharge grooves 64 are arranged, and a group of discharge plates 65 are slidably inserted in each group of discharge grooves 64, when the baffle 13 is released from the restriction, and moves outward under the action of spring one 14, until the baffle 13 passes through the discharge hole 15 and the feed groove 61, and pushes the baffle plate 63 to move toward the inside of the sedimentation collection box 6, until the spring four 62 is compressed to the limit distance, in this process, the solid impurities on one side of the baffle 13 are pushed into the sedimentation collection box 6.

[0044] By adopting the above scheme: through the sedimentation collection box 6, solid impurities can be separated in the processing barrel 1 and the drainage barrel 2 and then stored centrally, avoiding the direct discharge of solid impurities, facilitating subsequent management and processing, and reducing the frequent intervention of operators in the processing of solid impurities, thereby reducing the maintenance workload and the complexity of equipment maintenance.

[0045] The working principle of the present invention is: when in use, first pour the waste water and the medicine into the treatment barrel 1, then start the air pump 8, and input the air into the air inlet pipe 41 through the connecting pipe 7. When the air enters the air inlet pipe 41 from bottom to top, it will push the lifting cylinder 42 to rotate and rise along the guide block 411, and drive the stirring rod 43 to rotate, so as to mix the waste water and the medicine rich in microorganisms. During the rising process, the air will enter the treatment barrel 1 through the exhaust hole 1 413 and the exhaust hole 2 431, so as to promote the growth of microorganisms and the degradation of organic matter. When the lifting cylinder 42 rises to a certain height, the air pump 8 stops operating. As the air in the air inlet pipe 41 decreases, the thrust on the air inlet pipe 41 gradually decreases. When the thrust is less than the elastic force of the spring 2 45, the lifting cylinder 42 is pulled by the spring 2 45. Move down until spring 2 45 returns to its original length, then start air pump 8 again, repeat the operation, mix the wastewater with the agent containing microorganisms, and fully contact with air to increase the oxygen content, promote the growth of microorganisms and the degradation of organic matter, and make the microorganisms and suspended solids settle to the bottom of the treatment barrel 1 by gravity, remove the organic matter and suspended matter in the wastewater, and then start air pump 8 to maximum power, so that the lifting cylinder 42 rises quickly to the limit position. At this time, the lifting cylinder 42 is adsorbed by the magnetic disk 58 through the magnet embedded in the top, and then the air pump 8 is stopped. As the air in the intake pipe 41 decreases, under the action of spring 2 45, the lifting cylinder 42 moves downward, and drives the magnetic disk 58 to move downward. Under the action of the pull rope 55, the linkage plate 52 is pulled around the connection The block 51 rotates to dislocate the magnetic block 1 54 from the magnetic block 2 131, and the restriction of the baffle 13 is released. When the baffle 13 is released, it moves outward under the force of the spring 14 until the baffle 13 passes through the discharge hole 15 and the feed slot 61, and pushes the baffle plate 63 to move to the inside of the sedimentation collection box 6 until the spring 4 62 is compressed to the limit distance, exposing the filter hole 12, filtering the organic matter, suspended matter and solid impurities in the treatment barrel 1 through the filter hole 12, allowing the clean water to flow into the drainage barrel 2, and pushing the solid impurities on one side of the baffle 13 into the sedimentation collection box 6. After the solid impurities enter the sedimentation collection box 6, the microorganisms in the sedimentation collection box 6 are increased, so that the wastewater in the sedimentation collection box 6 reacts with the reagent in the sedimentation collection box 6 As the lifting cylinder 42 moves downward, and due to the length limitation of the pull rope 55 and the spring three 53, the magnetic disk 58 is separated from the lifting cylinder 42. At this time, the linkage plate 52 is reset under the action of the spring three 53, and the magnetic block 1 54 is aligned with the magnetic block 2 131. Under the repulsive force of the magnetic block 1 54 and the magnetic block 2 131, the baffle plate 13 is moved above the filter hole 12 to scrape off the solid impurities accumulated on the filter hole 12. The baffle plate 63 is reset under the action of the spring four 62 and abuts against the inner wall of the sedimentation collection box 6 again to prevent the solid impurities in the sedimentation collection box 6 from re-entering the processing barrel 1. Then the air pump 8 is started again to repeat the operation, so that the solid impurities in the sedimentation collection box 6 increase, the water level in the sedimentation collection box 6 is raised, and enters the processing barrel 1 through the baffle plate 63.And make the clean water in the treatment barrel 1 completely flow into the drainage barrel 2; a large amount of air is injected into the treatment barrel 1 through the air inlet pipe 41. The introduction of air not only increases the oxygen content of the system, but also effectively mixes the wastewater and the reagent by pushing the lifting cylinder 42 to rise and the stirring rod 43 to rotate. Such airflow and mechanical stirring can significantly increase the contact area between the wastewater and the reagent, accelerate the degradation of organic matter and the treatment process of the wastewater. The continuous supply and full mixing of air not only speeds up the treatment of the wastewater, but also effectively removes the organic matter and suspended matter in the wastewater, improves the quality of the treated water, and makes the final discharged water clearer. Through components such as the linkage plate 52, springs and magnetic blocks, the position of the baffle 13 can be automatically adjusted when the air pressure changes. This intelligent adjustment mechanism can respond to changes in air pressure in real time, automatically unlock or limit the baffle 13, thereby adjusting the opening and closing state of the filter hole 12. This automated design not only improves the stability of the system and reduces the complexity of manual operation, but also It can ensure the efficient operation of the equipment under different operating conditions, making the entire wastewater treatment process smoother and more reliable, easier to operate, and reducing the labor intensity of maintenance personnel. Through the functions of the sedimentation collection box 6, the discharge hole 15, the spring four 62, and the baffle plate 63, it can effectively manage the solid impurities in the treatment process. The sedimentation collection box 6 is specially used for centralized storage of solid impurities separated from the treatment barrel 1 and the drainage barrel 2. This centralized management method avoids the direct discharge of solid impurities and reduces the frequent intervention requirements for solid impurity treatment. Through the spring four 62 and the baffle plate 63, the solid impurities can be automatically pushed into the sedimentation collection box 6 during the treatment process, thereby ensuring that the filter hole 12 in the treatment barrel 1 remains unobstructed. This not only improves the treatment efficiency, but also reduces the maintenance frequency and complexity of the equipment, reduces the workload of operators, improves the convenience of use of the equipment and the overall management efficiency, and also facilitates the subsequent treatment and disposal of solid impurities.
