Description

Technical Field

[0001] The present invention relates to the field of sewage sludge treatment, and in particular to an ecological sewage plant sludge reduction and capacity expansion treatment device and process. Background Art

[0002] In the existing sewage treatment and sludge treatment processes, a multi-stage treatment process is usually adopted. First, the sewage is pre-treated and gravity sedimented in the primary sedimentation tank to remove some suspended solids and organic matter. Subsequently, the sewage enters the biological treatment stage, which usually includes anaerobic digesters and aerobic digesters. The anaerobic digester uses anaerobic microorganisms to decompose organic matter in an anaerobic environment, produce biogas and reduce the volume of sludge, while the aerobic digester further degrades organic matter in an aerobic environment and reduces the organic content of the sludge. After that, the sewage and sludge are subjected to subsequent treatment.

[0003] When sewage enters the reaction tank for sedimentation, the prior art separates the sewage and sludge by pumping away the sewage at the upper end of the reaction tank after the sludge has settled to the bottom of the reaction tank. However, when the sewage and sludge are pumped to the adjacent area, the water flow easily disturbs the sludge at the bottom and causes it to be mixed into the sewage again, resulting in the need for re-sedimentation and a waste of time.

[0004] In existing equipment, the anaerobic digestion and aerobic digestion processes of sludge can only be carried out separately in sequence, and after the anaerobic digestion is completed, the sludge will directly enter the aerobic digester and cannot be returned to the anaerobic digester for circulation treatment. It is difficult to flexibly adjust the treatment process according to actual needs, which may affect the overall treatment effect and resource utilization efficiency.

[0005] The patent with publication number CN116477757A discloses a municipal sewage continuous treatment equipment, which uses a separation diversion trough to preliminarily treat the sewage. The sewage flows in the spiral separation diversion trough, and relies on centrifugal force to gather solid debris to one side for subsequent screening. During the treatment process, water is supplied to the treatment chambers one by one by controlling the rotation of the closed baffle plate on the diversion pipe. The treatment chamber that is supplied with water first treats the sewage first. After the water supply to the remaining treatment chambers is completed, the treatment chamber that has been treated first is drained and new sewage to be treated is introduced.

[0006] However, the above equipment mainly relies on the activated sludge treatment tank to separate sewage and sludge. This method has poor separation effect, and many fine sludge particles often remain in the treated sewage. Moreover, the above equipment is difficult to ensure a good reaction environment for the treated material. The aeration component is greatly affected by the water flow, and the aeration volume and aeration time are difficult to accurately control, which cannot meet the optimal reaction conditions of microorganisms.

[0007] In terms of adjusting the reaction process, the treatment chamber is switched by relying on the water supply float to control the rotation of the closed baffle. This has poor stability and accuracy, and it is impossible to flexibly adjust the treatment process according to the actual characteristics of sewage and sludge, resulting in poor treatment effects and difficulty in achieving ideal treatment standards.

[0008] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technology for the treatment methods and processes of sewage sludge. Summary of the invention

[0016] Preferably, a partition component is provided in the reaction barrel to divide its internal area into two, and the partition component includes an inclined plate arranged on the inner wall of the reaction barrel, the inclined plate divides the area inside the reaction barrel into chamber one and chamber two, and two groups of strip grooves are symmetrically opened on the inclined plate, and the number of strip grooves in each group is several.

[0017] Preferably, a swing plate is hingedly connected to an inner wall of one side of the strip-shaped groove via a torsion spring.

[0018] Preferably, a discharge trough is provided at the bottom of the reaction barrel and penetrates into the interior thereof, and a blocking block is inserted into the discharge trough.

[0019] In addition, the present invention also provides an ecological sewage treatment plant sludge reduction and capacity expansion treatment process, comprising the following steps: S1, pouring sludge: pour the sludge from the top of the treatment barrel, and the filter disc will filter out the large impurities in the sludge to prevent the impurities from damaging the device.

[0020] S2, mud and water separation: the mud and water are left to stand, so that the sludge settles on the sliding plate, the sliding plate rises, so that the sewage is discharged through the drainage trough, the partition turns over, and the sludge falls through the semicircular groove to the bottom wall of the treatment barrel.

[0021] S3, mud and water transmission: sewage sludge is transmitted to the corresponding reaction barrels through pipeline components respectively, and the reaction barrels provide aerobic digestion and anaerobic digestion environment for the corresponding sewage and sludge.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present invention can effectively separate sewage and sludge by arranging components such as a sliding disk, a semicircular groove, a partition and a main cylinder in a processing barrel. The sliding disk slides up and down in the processing barrel, and the partition rotates in the semicircular groove. When the partition is laid flat, the semicircular groove can be blocked, so that the sewage and sludge are allowed to stand still on the sliding disk. After the sludge settles, the sliding disk rises, and the sewage is discharged from the drainage groove. Then the partition flips over, and the sludge falls into the main cylinder through the semicircular groove and finally enters the pipeline assembly, thereby ensuring the separation effect of sewage and sludge, while avoiding damage to subsequent devices by impurities, and ensuring the stability and reliability of the treatment process.

[0024] 2. The present invention realizes efficient sludge dehydration by arranging a filter press plate and an annular groove at the bottom of the processing barrel, combined with the squeezing effect of the sliding disc and the partition. The sliding disc and the partition exert pressure on the sludge during the downward movement, and the moisture in the sludge is discharged through the tiny holes on the filter press plate. The oblique cross-section design of the annular groove allows the moisture to flow into the connecting pipe under the action of gravity, and finally enter the bent pipe and flow into the reaction barrel, which effectively reduces the sludge volume, increases the solid content of the sludge, avoids the disturbance of the water flow to the sludge, improves the dehydration efficiency, and reduces the subsequent treatment cost.

[0025] 3. The present invention realizes precise control of the reaction process by arranging a partition assembly and multiple valves in the reaction barrel. The inclined plate in the reaction barrel divides the reaction barrel into a first chamber and a second chamber, which are used for aerobic and anaerobic digestion reactions respectively. The design of the swing plate allows the transfer of sludge or sewage between the first chamber and the second chamber to be carried out in an orderly manner, avoiding mixing and interference of the reaction environment.

DETAILED DESCRIPTION

[0047] The following combination Figures 1 to 19 Embodiments of the present invention are described in detail.

[0048] The embodiment of the present application discloses an ecological sewage plant sludge reduction and expansion treatment device and process, which is used for sludge treatment; first, the large impurities in the sludge are separated to prevent them from affecting the subsequent treatment process, then, the sewage and sludge are effectively separated, and the separated sludge is transported to a specific link. During the transportation process, the sludge is pressed and dehydrated to reduce the sludge volume and increase the solid content, thereby reducing the subsequent treatment cost. Subsequently, the sewage and sludge are placed in different reaction environments for treatment, and the residence time of the materials in different reaction environments is flexibly adjusted by regulating the rotation direction and speed of the reaction container, and additives can be added through specific openings to optimize the reaction environment.

[0049] Example 1: Reference Figure 1and Figure 2 As shown, it includes a base plate 1, a processing barrel 10, a filter disc 11, a separation unit 2, a drainage trough 12, a reaction barrel 13 and a pipeline assembly 4. The processing barrel 10 is located at the upper end of the base plate 1. A filter disc 11 is arranged on the inner wall of the processing barrel 10. The filter disc 11 is used to separate large impurities in the sludge to prevent the large impurities from causing damage to subsequent devices.

[0050] A separation unit 2 for separating sewage and sludge is slidably arranged inside the treatment barrel 10; a drainage groove 12 is provided on one side of the treatment barrel 10, and sewage can be discharged from the treatment barrel 10 through the drainage groove 12; two reaction barrels 13 are installed on the bottom plate 1, and the reaction barrels 13 are connected to the treatment barrel 10 through a pipe assembly 4, and the separated sludge and sewage will enter the corresponding reaction barrels 13 through the pipe assembly 4 for aerobic and anaerobic digestion reactions.

[0051] Continue to refer to Figure 2 and Figure 3 As shown, a separation unit 2 is used to separate sewage and sludge; specifically, the separation unit 2 includes a sliding disk 20, a semicircular groove 21, a partition 22 and a main cylinder 23. The sliding disk 20 is slidably set on the processing barrel 10, that is, the sliding disk 20 can slide up and down in the processing barrel 10.

[0052] Two semicircular grooves 21 are symmetrically provided on the sliding plate 20, and several partitions 22 are rotatably arranged in the semicircular grooves 21. An external driving motor is installed on the inner wall of one side of the semicircular grooves 21. The external driving motor is connected to the rotating end of the partition 22 to drive the partition 22 to rotate in the semicircular grooves 21. When the partitions 22 are all in a flat state, several corresponding partitions 22 can block the semicircular grooves 21, so that sewage and sludge can fall on the sliding plate 20 and the partitions 22. After standing for a period of time, the sludge and some impurities settle. At this time, the sliding plate 20 is driven upward by external force, so that the sewage corresponds to the drainage groove 12, and the sewage is discharged from the drainage groove 12 to the outside of the treatment barrel 10. When the drainage groove 12 is level with the sludge, the movement is stopped, and the partition 22 is turned over, so that the semicircular groove 21 is no longer blocked, and the sludge on the partition 22 will fall through the semicircular groove 21 to the bottom wall of the treatment barrel 10, and the separation of sewage and sludge can be completed at this time.

[0053] A main cylinder 23 connected to the bottom of the sliding disk 20 is slidably provided at the bottom of the processing barrel 10, and the bottom of the main cylinder 23 is connected to the pipeline assembly 4, that is, the sludge dropped on the bottom of the processing barrel 10 can enter into the main cylinder 23 and drop into the pipeline assembly 4 through the main cylinder 23, and the main cylinder 23 can drive the sliding disk 20 to move up and down when driven by external force.

[0054] Reference Figure 4 and Figure 5As shown, the main barrel 23 is located on one side of the treatment barrel 10 and a stirring assembly 3 is also provided; specifically, the stirring assembly 3 includes a feed trough 30, a rotating frame 31, an arc plate 32 and an auger rod 33. The feed trough 30 is opened on the outside of the main barrel 23, that is, the sludge on the inner wall of the treatment barrel 10 can enter the main barrel 23 through the feed trough 30.

[0055] A rotating frame 31 corresponding to the feed trough 30 is rotatably arranged on the outside of the main barrel 23, and several arc-shaped plates 32 located in the processing barrel 10 are slidably arranged on the outside of the rotating frame 31. An auger rod 33 located in the main barrel 23 is rotatably arranged at the bottom of the sliding disk 20. The rotating frame 31 and the auger rod 33 can be rotated under the drive of an external driving device, and the arc-shaped plate 32 can collect the sludge in the processing barrel 10 into the feed trough 30 when rotating. The sludge enters the main barrel 23 through the notch on the rotating frame 31 and the feed trough 30. The auger rod 33 in the main barrel 23 rotates to drive the sludge to move, so that the sludge enters the pipeline assembly 4 from the opening at the other end thereof, and the external driving device mentioned above can be installed at the bottom of the sliding disk 20, so that the driving end of the driving device can be connected to the auger rod 33 and the rotating frame 31 respectively.

[0056] Reference Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, it is used to transfer the sewage and sludge in the treatment barrel 10 to the pipeline assembly 4 in the corresponding reaction barrel 13; specifically, the pipeline assembly 4 includes a connecting cylinder 40, a drop groove 41, a swing circular plate 42, a bending tube 43, an annular groove 44, a filter press plate 45, a connecting pipe 46, an L-shaped support plate 47 and a fixed plate 48, the two connecting cylinders 40 are respectively located at the upper ends of the two reaction barrels 13, and the reaction barrel 13 is provided with a drop groove 41 corresponding to the end of the connecting cylinder 40, and the inner wall of the drop groove 41 is hinged with a swing circular plate 42 through a torsion spring.

[0057] The bottom of the main cylinder 23 extends to the connecting cylinder 40 on one side, and a bent tube 43 connected to the drainage groove 12 is provided in the connecting cylinder 40 on the other side. The sludge falls from the bottom opening of the main cylinder 23 to the corresponding connecting cylinder 40, and falls from the connecting cylinder 40 to the swinging circular plate 42 again, driving the swinging circular plate 42 to swing, and no longer blocking the falling groove 41, so that the sludge can fall into the corresponding reaction barrel 13, and then the swinging circular plate 42 can be driven by the torsion spring to swing back again, and the swinging circular plate 42 will not swing toward the outside of the reaction barrel 13 under the limitation of the corresponding torsion spring, but will only swing toward the inside of the reaction barrel 13.

[0058] The sewage discharged from the drainage trough 12 can enter the bent pipe 43 and then be discharged into the corresponding reaction barrel 13 from the bent pipe 43. During this process, the corresponding swing circular plate 42 will also flip so that the sewage can enter the reaction barrel 13 through the drop trough 41.

[0059] An annular groove 44 is provided at the bottom of the treatment barrel 10, and a filter press plate 45 located at the upper end of the annular groove 44 is provided at the bottom of the treatment barrel 10, and a connecting pipe 46 is provided through the outside of the treatment barrel 10, and the two sides of the connecting pipe 46 are respectively connected with the annular groove 44 and the bending pipe 43. Before the sludge enters the main cylinder 23, the sliding plate 74 is first moved downward to squeeze the sludge through the sliding disk 20 and the partition 22. In the process of the sliding plate 74 moving downward, the sliding disk 20 and the partition 22 will exert downward pressure on the sludge, and the filter press plate 45 is fixed at the upper end of the annular groove 44 to form a stable supporting surface. As the sliding plate 74 descends, the sludge is gradually compressed, and the water in the sludge is forced to be discharged through the tiny holes on the filter press plate 45 under strong pressure. These holes are designed to be very small. , which can prevent sludge particles from passing through and only allow water to flow out. The squeezed water enters the annular groove 44. Since the cross-section of the annular groove 44 is oblique, the water naturally flows into the connecting pipe 46 under the action of gravity, and the connecting pipe 46 passes through the outside of the treatment barrel 10 and is connected to the bent pipe 43. Therefore, the water will flow along the connecting pipe 46, and finally enter the bent pipe 43, and flow into the corresponding reaction barrel 13 through the bent pipe 43, fully squeezing out the water in the sludge, reducing the volume of the sludge, and increasing the solid content of the sludge, thereby reducing the cost of subsequent treatment and disposal. At the same time, the design of the annular groove 44 and the connecting pipe 46 also avoids the disturbance of the water flow to the sludge, prevents the sludge from being mixed with water again, and improves the dehydration efficiency. In addition, the bent pipe 43 can guide the water flow to the designated reaction barrel 13, which is convenient for subsequent treatment and utilization.

[0060] During the pressing process, the corresponding arc plate 32 will contact the upper end of the filter press plate 45 and move upward on the corresponding rotating frame 31 to avoid collision with the filter press plate 45 and interference with the moving path of the sliding plate 20 .

[0061] Two L-shaped support plates 47 are symmetrically arranged on the bottom plate 1, and a fixing plate 48 is commonly arranged on the upper end of the L-shaped support plates 47. Both sides of the fixing plate 48 are respectively connected to the outer sides of the corresponding connecting tubes 40. The L-shaped support plates 47 are used to support the fixing plates 48, and the fixing plates 48 are used to support the corresponding connecting tubes 40. On this basis, the connecting tube 40 and the bending tube 43 on one side can also support the processing barrel 10.

[0062] Reference Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, a partition assembly 5 is provided in the reaction barrel 13 to divide its internal area into two; specifically, the partition assembly 5 includes a conical plate 50, an inclined plate 51, a swing plate 52, a blocking block 53, a drive shaft 54, a drive gear 55, a support plate 56, an arc-shaped rack 57 and a valve 58, two groups of symmetrically distributed conical plates 50 are arranged on the upper end of the bottom plate 1, and the reaction barrel 13 is located between the two conical plates 50 of the corresponding group and is rotationally connected thereto, the reaction barrels 13 are connected by a belt drive, a drive motor is provided on the conical plate 50 on one side through a motor seat, the output shaft of the drive motor is connected to the end of the reaction barrel 13, and the drive motor synchronously drives the two reaction barrels 13 to rotate under the cooperation of the belt drive and the corresponding conical plates 50.

[0063] An inclined plate 51 is provided on the inner wall of the reaction barrel 13, and the inclined plate 51 divides the area inside the reaction barrel 13 into a first chamber and a second chamber, that is, the corresponding first chamber and second chamber can be used as reaction spaces for aerobic digestion and anaerobic digestion environments of sewage and sludge, so that sewage and sludge can react in the first chamber and the second chamber respectively, and there will be no interference between the first chamber and the second chamber. When sewage or sludge enters the corresponding reaction barrel 13 through the corresponding drop trough 41, it will first enter the first chamber, that is, an aerobic digestion or anaerobic digestion environment is arranged in the first chamber according to actual needs, so that sewage and sludge can react.

[0064] Two groups of strip grooves are symmetrically provided on the inclined plate 51, and the number of strip grooves in each group is several. A swing plate 52 is hinged on the inner wall of one side of the strip groove through a torsion spring. The swing plate 52 can swing in the corresponding strip groove when driven by an external force, and due to the limitation of the torsion spring, the swing plate 52 can only swing counterclockwise. When the reaction barrel 13 rotates counterclockwise, the sludge or sewage in one chamber will move to one side of the inclined plate 51. At this time, the swing plate 52 opens, and the sludge or sewage in one chamber will enter the second chamber, that is, from the aerobic digestion environment to the anaerobic digestion environment, and the transfer can be completed.

[0065] In practical applications, if the reaction degree of sludge or sewage is to be increased, the reaction barrel 13 is driven to rotate again, so that the sludge or sewage can be moved to the side of the inclined plate 51 again, and the swing plate 52 is opened again, and the sludge or sewage will be moved into the first chamber again. When the reaction barrel 13 rotates clockwise, the sludge or sewage will not enter the second chamber through the swing plate 52, because the swing of the swing plate 52 in the counterclockwise direction is limited by the torsion spring. This unidirectional swing design ensures that the transfer of sludge or sewage between the first chamber and the second chamber is controllable and orderly, thereby avoiding mixing and interference of the reaction environment.

[0066] By reasonably controlling the rotation direction and speed of the reaction barrel 13, the residence time of the sludge or sewage between the first chamber and the second chamber can be flexibly adjusted to meet different treatment requirements. For example, in an aerobic digestion environment, the sludge or sewage requires a longer residence time to ensure the full degradation of organic matter, while in an anaerobic digestion environment, different residence times may be required to optimize the production of biogas. In addition, the design of the swing plate 52 not only realizes the transfer of sludge or sewage, but also plays a stirring role to a certain extent, promotes the uniform mixing of substances in the reaction barrel 13, and improves the reaction efficiency. The combined design of the strip grooves on the inclined plate 51 and the swing plate 52 makes the entire reaction process more flexible and efficient. By adjusting the speed and direction of the motor, precise control of the sludge or sewage treatment process can be achieved. For example, when it is necessary to extend the residence time of the sludge in the first chamber to improve the aerobic digestion effect, the speed of the motor can be reduced. Conversely, when it is necessary to speed up the transfer speed to meet the needs of anaerobic digestion, the speed of the motor can be increased.

[0067] A discharge trough corresponding to the second chamber is provided at the bottom of the reaction barrel 13, and a sealing block 53 is inserted in the discharge trough. Finally, after the sludge or sewage completes the reaction, the sludge or sewage can be driven to move into the second chamber again, and the sealing block 53 is opened to no longer block the discharge trough, so that the sludge or sewage that has completed the reaction is discharged from the reaction barrel 13 through the discharge trough for the next stage of treatment.

[0068] The hinges of the swing plates 52 of each group are connected to each other by belt transmission. A driving shaft 54 ​​connected to the hinges of the swing plates 52 on one side of each group is symmetrically rotatable on the reaction barrel 13. A driving gear 55 is provided at one end of the driving shaft 54 ​​located outside the reaction barrel 13. When driven by an external force, the driving gear 55 can drive the swing plates 52 on one side to swing through the corresponding driving shaft 54. A group of swing plates 52 can be swung synchronously by belt transmission, so as not to block the strip grooves, so that sludge or sewage can be moved to one chamber or the second chamber through the strip grooves. The two groups of swing plates 52 are driven by two swing plates 52 respectively. In the initial state, the swing plates 52 are parallel to the strip grooves under the drive of the corresponding torsion springs. Even if there is sludge or sewage on the swing plates 52, they will not swing.

[0069] A support plate 56 is provided on the outer side of the conical plate 50, and an arc-shaped rack 57 corresponding to the driving gear 55 on one side is provided at the end of the support plate 56. When the reaction barrel 13 rotates counterclockwise, the driving gear 55 on one side will be driven to engage with the arc-shaped rack 57, and the driving gear 55 will drive the corresponding group of swing plates 52 to swing. At this time, the sludge and sewage are located on one side of the corresponding group of swing plates 52. The swing plate 52 flips over, and the corresponding sewage or sludge will be transferred to another chamber (chamber one or chamber two). When the driving gear 55 is no longer engaged with the arc-shaped rack 57, the swing plate 52 will flip back under the drive of the corresponding torsion spring to continue to seal the strip groove.

[0070] Several valves 58 are symmetrically provided on the outside of the reaction barrel 13. Two groups of valves 58 are respectively connected to the first chamber and the second chamber. By opening the valves 58, various additives required for aerobic and anaerobic environments can be regularly added to the first chamber or the second chamber. In the aerobic chamber, nitrifying bacteria activators can be added, such as preparations containing special enzymes or nutrients, which can enhance the activity of nitrifying bacteria, accelerate the conversion of ammonia nitrogen, and improve the efficiency of aerobic denitrification; dissolved oxygen enhancers, such as calcium peroxide, can release oxygen to ensure microbial respiration and denitrification reactions when the concentration of organic matter in sewage suddenly increases and causes insufficient dissolved oxygen; nutritional supplements, such as composite microbial nutrient salts containing nitrogen, phosphorus, and potassium, can provide comprehensive nutrition for microorganisms, maintain their growth and reproduction and population stability, and ensure efficient denitrification reactions.

[0071] In the anaerobic second chamber, the anaerobic denitrifying bacteria agent is made of specific strains, which can enhance denitrification, convert nitrate nitrogen into nitrogen gas, and reduce the total nitrogen content; when the carbon-nitrogen ratio is unbalanced, carbon source supplements such as methanol and sodium acetate are added to provide electron donors for anaerobic denitrifying bacteria and promote the denitrification reaction; adding pH adjusters such as sodium bicarbonate can maintain the acid-base balance of the anaerobic environment and ensure the stable operation of the anaerobic denitrification reaction.

[0072] In practical applications, the valve 58 can provide a convenient way for the application of the MPCS technology (a known technology); with the help of the port of the valve 58, the relevant components and materials of the MPCS technology can be introduced into the reaction barrel 13.

[0073] MPCS technology utilizes the impact of pollutants in sewage biochemical units on the growth and reproduction conditions of microorganisms. Based on the established data model, it can achieve the highest activity and reproduction rate of the bacterial flora in the biochemical unit through precise control, forced interference, in-situ bacterial community optimization screening, immobilization technology, etc.

[0074] In an aerobic chamber, MPCS technology catalyzes in-situ microorganisms based on specific biocatalytic materials and equipment. Its specific catalytic materials optimize the structure of reorganized microbial communities, improve the reproduction and screening of heterotrophic denitrifying bacteria, and strengthen the screening of denitrifying microorganisms, and work synergistically with the original nitrifying bacteria activators, dissolved oxygen enhancers, and nutritional supplements. By improving the activity of microorganisms, the conversion of ammonia nitrogen is further accelerated, the efficiency of aerobic denitrification is enhanced, and the decomposition of other pollutants by microorganisms is promoted, thereby improving the overall treatment effect.

[0075] In the anaerobic second chamber, MPCS technology can also play a key role; using targeted carbon source induction, denitrifying bacteria represented by Pseudomonas are rapidly enriched, and the relative abundance of denitrifying bacteria is greatly increased. This works together with the added anaerobic denitrifying bacteria and carbon source supplements to significantly enhance denitrification, more efficiently convert nitrate nitrogen into nitrogen gas, and reduce the total nitrogen content of sewage. By utilizing the strong denitrification electron supply specificity and targeted energy supply of specific catalytic materials, the activity of enzymes in microorganisms is increased, the periplasmic electron transfer process of microbial cells and the transmembrane transport of nitrogen-containing compounds are accelerated, the expression of multiple denitrification-related genes of microorganisms is promoted, the biological competitiveness of microorganisms is enhanced, and the anaerobic reaction environment is further optimized to ensure the stable and efficient operation of anaerobic denitrification reactions.

[0076] In addition, the process equipment in the MPCS system promotes the rapid reproduction of the selected in-situ bacteria, fully exerts its function, and completes the activation, screening and cultivation of microorganisms; using the MPCS system equipment, the dominant strains of indigenous microorganisms that are beneficial to the removal of pollutants are domesticated in the form of a process, and work together with the original microorganisms in the reaction barrel 13, so that the entire biochemical system can operate more efficiently and stably, achieve deep decomposition of harmful substances in sewage and sludge, and improve the quality of sewage treatment.

[0077] During the application of MPCS technology, all kinds of auxiliary equipment required can be connected to the outside of the reaction barrel 13 through the port of valve 58 to maintain the stability of the MPCS reaction environment inside the reaction barrel 13 and ensure that the MPCS reaction is carried out efficiently under suitable conditions.

During subsequent cleaning, the sliding disc 20 is driven to rise, and the partition 22 of the sliding disc 20 is flipped ninety degrees during the rising process. After the sliding disc 20 contacts the bottom wall of the filter disc 11, the partition 22 will be inserted into the corresponding transverse groove 60 to dredge the transverse groove 60, and the sliding disc 20 continues to drive the filter disc 11 to rise close to the port of the processing barrel 10, so that the operator can clean up the large impurities on the upper end of the filter disc 11.

The cylinder bracket 70 is provided on the bottom plate 1, and one end thereof extends between the two reaction barrels 13. A double-axis cylinder 71 is provided at the end of the cylinder bracket 70. The main barrel 23 is located in the processing barrel. A passive plate 72 corresponding to the upper end axis of the double-axis cylinder 71 is provided on one side of the outer side of 10, and the cylinder bracket 70 is used to support the double-axis cylinder 71, and the telescopic axis of the double-axis cylinder 71 moves upward until it contacts the passive plate 72, so that the sliding plate 20 can be indirectly driven to rise through the passive plate 72. When the telescopic axis of the double-axis cylinder 71 descends, the corresponding sliding plate 20 will also descend under the driving force of gravity, that is, when the sludge is pressed and drained, it is pressed by the weight of the sliding plate 20 and the main cylinder 23 itself to prevent the pressing force from being too large, so that the sludge enters the filter press plate 45 and causes clogging of the filter press plate 45.

[0080] The conical plate 50 is provided with a limiting groove 73, and a sliding plate 74 is slidably provided between the corresponding limiting grooves 73 at the front and rear.

A connecting plate 77 is provided between the sliding plate 74 and the inner bottom wall of the corresponding limiting groove 73. The reset push spring 78 drives the corresponding sliding plate 74 to be located in the middle of the limit groove 73 in the initial state, and the sliding plate 74 can move up and down under the limit of the corresponding limit groove 73 when driven by external force, and the telescopic shaft of the double-axis cylinder descends and contacts with the connecting plate 77 in the middle of the sliding plate 74, and indirectly drives the connecting plate 77 to move downward, and the rectangular block 75 will pull the blocking block 53 out of the discharge trough through the cooperation of the arc groove and the plug-in plate 76 to discharge the sewage and sludge that have completed the reaction.

[0081] When the reaction barrel 13 rotates, the blocking block 53 will drive the insertion plate 76 to rotate synchronously, and the axis of the insertion plate 76 and the arc groove coincides with the axis of the reaction barrel 13, that is, the insertion plate 76 can move out of the corresponding arc groove when following the rotation of the reaction barrel 13, and when the reaction barrel 13 rotates to its original position, the insertion plate 76 will be inserted into the arc groove again.

[0082] When the blocking block 53 is pulled out and wants to be inserted back into the discharge trough, the discharge trough at the bottom of the reaction barrel 13 is driven to correspond to the blocking block 53. At this time, the telescopic shaft of the double-axis cylinder 71 no longer interferes with the connecting plate 77, and the reset push spring 78 can push the sliding plate 74 to move to the initial height. At this time, the blocking block 53 will be reinserted into the discharge trough to seal it.
