Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for livestock farming. Background Technology

[0002] Livestock farming wastewater pollution is a typical problem of non-point source pollution. The main pollutants in the wastewater include ammonia nitrogen, nitrite, organic matter, phosphorus, and fouling organisms. At present, using compound microbial agents to achieve efficient biological fermentation treatment of livestock farm wastewater is a relatively economical and efficient method.

[0003] In livestock wastewater treatment, the current conventional process involves injecting wastewater into a mixing tank, followed by manual injection of compound microbial agents, either once or in batches. Multiple additions of agents increase the labor intensity and management costs for operators. Furthermore, the pursuit of rapid and thorough mixing often results in excessively high mixing intensity, generating severe hydraulic shear forces that tear and break down the microbial flocs. This leads to a continuous decrease in effective biomass within the mixing tank and subsequent treatment units, directly weakening the system's pollutant degradation capacity. Conversely, low-speed mixing results in uneven distribution of the agents in the wastewater, with some areas having excessively high or low concentrations, failing to create an optimal reaction microenvironment. This reduces the effective contact and reaction efficiency between the compound microbial agents and the livestock wastewater, significantly weakening the degradation rate and removal rate of target pollutants. It can also lead to unstable treatment processes, fluctuating effluent quality, and even the need for additional agent replenishment or extended mixing time, thus significantly increasing overall treatment costs and reducing the reliability and efficiency of wastewater treatment.

A bacterial outlet tube is fixedly installed on the top of the annular top plate at the top of the arc-shaped connecting plate. A piston plate is movably installed at the bottom of the inner part of the bacterial outlet tube. A piston rod is installed at the bottom of the piston plate, and the bottom end of the piston rod passes through the bacterial outlet tube and is installed at the top of the toothed plate. An arc-shaped guide pipe is fixedly installed between the bottom of the bacterial liquid tube and the bacterial liquid ring, and the arc-shaped guide pipe allows the bacterial liquid tube and the bacterial liquid ring to communicate through each other. A U-shaped conduit is connected between the top of the bacterial outlet tube and the bacterial liquid ring. A spray head is fixedly installed on the top of the bacterial outlet tube.

[0011] As a preferred embodiment of the present invention, the mixing assembly further includes an annular internal gear and a driving gear.

A rotating plate is fixedly installed at the bottom end of the rotating rod, and the driving gear is movably connected to the rotating plate. The driving gear and the annular internal gear are movably meshed. An S-shaped mixing rod is fixedly installed at the bottom center of the driving gear, and the S-shaped mixing rod moves inside the annular fixed plate.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: In this invention, an arc-shaped drive rod in the flipping convection assembly is embedded in a pre-set V-shaped flipping groove. As the arc-shaped connecting plate rotates, the inclined surface of the V-shaped flipping groove forces the flipping rod to drive the arc-shaped flipping plate to flip, effectively solving the problem of "dead water" at the bottom of the pool. Through the regular flipping of the arc-shaped flipping plate, forced mechanical stirring is applied directly to the water body with extremely poor flow at the edge of the pool bottom, significantly enhancing the mixing efficiency between the "dead water" zone and the main water flow, accelerating the diffusion and mass transfer process of dissolved oxygen, microorganisms, pollutants, and nutrients, avoiding local anaerobic environments or pollutant accumulation. By eliminating hydraulic dead zones, the hydraulic conditions and biochemical reaction environment in the entire reaction tank are ensured to be more uniform, thereby significantly improving the overall wastewater treatment efficiency and stability, optimizing the overall hydraulic flow field in the tank, and the flipping stirring method can usually provide a gentler hydraulic shear force, which helps to protect the integrity of the bacterial flocs and reduce the risk of floc breakage and biomass loss caused by strong shear, meeting the needs of microbial treatment processes.

[0013] In this invention, the rotating toothed plate in the bacterial discharge component drives the annular pressure plate to move up and down. When the toothed plate drives the annular pressure plate to descend synchronously, the pressure plate applies downward vertical pressure to the water below, causing the wastewater directly below the pressure plate to move downward and radially. According to the principle of fluid continuity, the pressure-displaced wastewater will surge upward to the outer area of ​​the pressure plate, forming a stable vertical circulation. This surge significantly improves the flow of wastewater in the lower layer of the treatment tank. At the same time, the vertical circulation and surge process produce stable shearing, entrainment and mixing effects on the existing wastewater and compound microbial agents in the tank, forcibly merging the two like "kneading dough". This greatly improves the overall turbulence intensity and three-dimensional flow of the wastewater inside the treatment tank, effectively breaking down stratification and eliminating relatively static areas.

[0014] In this invention, the rotating toothed plate in the microbial feeding assembly drives the annular pressure plate to move up and down. When the toothed plate drives the annular pressure plate to rise synchronously, the pressure plate generates an upward traction force on the water above and attached to it during the ascent. The rise of the pressure plate creates a momentary low-pressure zone below, prompting the surrounding and lower water to quickly replenish upwards, forming an upward suction flow. This stable upward water flow has a highly efficient entrainment and tumbling effect on the compound microbial agent that has just been sprayed into the treatment tank, quickly bringing it into the water body. The suction flow accelerates the dispersion and diffusion of the fermentation agent in the vertical and horizontal directions, greatly shortening its [processing time]. The mixing time with the main wastewater prevents the bacterial agent from floating or accumulating on the water surface, ensuring that the newly added bacterial agent can be quickly and evenly distributed to all areas of the treatment tank, especially the middle and lower water layers. The alternating pressing and pulling of the pressure plate continuously stimulates stable and gentle vertical circulation and radial flow in the tank, forming a complex three-dimensional turbulent field. This overcomes the mixing dead zones that may exist in traditional horizontal stirring. The shear force generated by the large-area vertical reciprocating motion is more widely distributed, with a relatively low and more uniform peak value. This helps to reduce the risk of mechanical damage to the bacterial flocs while achieving thorough mixing, which is beneficial for maintaining biomass stability and treatment efficiency.

[0015] In this invention, the semi-gear meshing with the rack plate in the flipping bacterial discharge component causes a lifting and lowering motion. The flipping motion of the arc-shaped flipping plate powerfully lifts the low-temperature, low-oxygen wastewater rich in sediment or metabolic waste at the bottom of the treatment tank to the middle and upper water layers. The newly sprayed bacterial agent is still in the surface or shallow layer of the water. The water flow lifted from the bottom meets and envelops the falling bacterial agent. The rising water flow and the falling bacterial agent flow undergo intense convergence, collision and entrainment in the middle and upper water layers. The tumbling water flow generated by the arc-shaped flipping plate is like a dynamic mixing chamber, which exerts a gentle shearing, stretching and mixing effect on the bacterial agent and wastewater. This bottom-up "lifting" mixing effectively prevents the lighter bacterial agent from floating on the water surface or only spreading on the surface, and also avoids its local accumulation below the spray point.

[0016] In this invention, the inverted bacterial dispensing component achieves zero delay between bacterial agent addition and initial mixing. The bacterial agent is immediately entrained in a strong mixing flow upon entering the water body, maximizing its initial high activity and significantly shortening the time required for the agent to adapt to the environment and initiate metabolism. The water flow rising from the bottom carries wastewater with different physicochemical properties (such as temperature, pH, and substrate concentration), which is forcibly mixed with the new bacterial agent on the surface. This accelerates the diffusion and uniform distribution of the bacterial agent throughout the vertical direction of the water body, avoiding the formation of concentration gradients and rapidly carrying the new bacterial agent into the middle layer of the water body. This region typically has better dissolved oxygen levels and temperature conditions (compared to the surface layer). The environment, which is susceptible to temperature fluctuations and may be oxygen-deficient at the bottom, provides a more favorable environment for the rapid activation and efficacy of the bacterial agent. Stable turbulent mixing greatly increases the contact frequency and contact area between the bacterial agent, pollutants, and dissolved oxygen, significantly improving the initial rate and overall efficiency of the biochemical reaction. It quickly mixes the bacterial agent into the main body of the water, reducing the possibility of it being deactivated by ultraviolet radiation on the water surface or being carried away by the ventilation airflow. Utilizing the existing kinetic energy of the arc-shaped flip plate used to eliminate "dead water", it simultaneously completes the powerful initial mixing of the newly added bacterial agent, achieving a dual benefit of energy input and improving the overall energy efficiency of the system.

[0017] In this invention, a system is created by precisely driving the half-gear and the rack plate in the incubation component to achieve negative pressure suction and positive pressure injection of the microbial agent through the incubation tube, and strictly and synchronously triggering the arc-shaped flipping plate to lift the bottom wastewater. This innovatively solves the key problems of slow initial diffusion and uneven mixing after the microbial agent is added. Through the precise spatiotemporal coordination of mechanical design, the microbial agent is mixed instantly, deeply and uniformly with the wastewater at the optimal time when it enters the water body, using forced turbulence from bottom to top. This significantly improves the utilization efficiency of the compound microbial agent and the overall performance of the wastewater treatment system.

[0018] In this invention, the arc-shaped guide pipe in the mixing convection component moves synchronously with the annular top plate. The annular convection ring around the arc-shaped guide pipe is immersed in the wastewater. The rotational motion generates a forced circumferential flow in the wastewater, driving the internal wastewater and composite microbial agent to form a three-dimensional tumbling mixture, significantly improving the turbulence intensity of the main area. When the bacterial liquid cylinder rotates, the rotating rod in the stirring and mixing component drives the rotating plate to revolve. The active gear installed on the rotating plate meshes with the fixed annular internal gear to form a precision transmission. The S-shaped rod rotates to achieve stable mixing of the wastewater and bacterial agent flowing through its gaps. The revolving motion continuously draws multiple streams of water from the periphery to the stirring core area, achieving forced fluid convergence throughout the entire area. Through the spatiotemporal synergy of forced circulation at the top, bottom tumbling convection, and planetary stirring in the middle layer, a triple breakthrough is achieved at the fluid dynamics level, ultimately achieving triple optimization of mixing efficiency, biocompatibility, and energy consumption control.

A reversing convection assembly is installed around the bottom of the treatment tank 10 to agitate the wastewater. An arc-shaped reversing plate 25 within the reversing convection assembly agitates the wastewater around the bottom of the treatment tank 10.

The reversing convection assembly also includes… An annular fixing plate 30 is provided at the bottom of the annular top plate 20. An arc-shaped fixing rod 31 is fixedly installed around the bottom of the treatment pool 10. A triangular flipping opening 32 for flipping the arc-shaped flipping plate 25 is opened around the bottom of the annular fixing plate 30. An L-shaped connecting rod 33 is fixedly installed at the top of the triangular flipping opening 32. A triangular flipping block 34 is provided at the bottom of the triangular flipping opening 32. A V-shaped flipping groove 35 is formed between the triangular flipping block 34 and the annular fixing plate 30. The triangular flipping block 34 is installed at the bottom end of the L-shaped connecting rod 33, and the L-shaped connecting rod 33 is installed at the top end of the arc-shaped fixing rod 31.

[0023] See Figure 3 , Figure 5 , Figure 6 and Figure 8 An arc-shaped connecting plate 21 is fixedly installed around the bottom of the annular top plate 20. A flipping rod 22 is movably installed at the bottom of the arc-shaped connecting plate 21. An arc-shaped driving plate 23 is fixedly installed at one end of the flipping rod 22 near the annular fixed plate 30. Arc-shaped driving rods 24 that match the size of the V-shaped flipping groove 35 are fixedly installed at both ends of the arc-shaped driving plate 23. The arc-shaped driving rods 24 move in the V-shaped flipping groove 35. An arc-shaped flipping plate 25 is installed at the end of the flipping rod 22 away from the annular fixed plate 30. The arc-shaped flipping plate 25 has a flipping hole 26.

[0024] See Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The bacterial culture cylinder 50 drives the annular top plate 20 at the top of the annular fixed plate 30 to rotate slowly and uniformly through the arc-shaped guide pipe 51. The annular top plate 20 achieves stable rotation under the action of the annular limiting ring, the annular limiting groove 28, and the annular limiting block 29. The annular top plate 20 drives the arc-shaped flipping plate 25 to rotate at the bottom of the treatment tank 10 through the arc-shaped connecting plate 21. When the arc-shaped connecting plate 21 moves to the triangular flipping block 34, the arc-shaped driving rod 24 at one end of the arc-shaped driving plate 23 enters the top of the V-shaped flipping groove 35 through the push of the triangular flipping block 34. Meanwhile, the arc-shaped drive rod 24 at the other end of the arc-shaped drive plate 23 moves to the bottom position of the triangular flip block 34. During the continuous rotation of the arc-shaped connecting plate 21, the arc-shaped drive rod 24 at the bottom of the triangular flip block 34 moves along the bottom of the triangular flip block 34. The arc-shaped drive rod 24 in the V-shaped flip groove 35 causes the arc-shaped drive plate 23 to flip.

The arc-shaped flip plate 25 will drive the "dead water" around the bottom of the treatment pool 10 to move and convect.

[0025] See Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The rotating rod 22 is also equipped with a rotating inoculum outlet component. When the arc-shaped rotating plate 25 rotates, it works in conjunction with the inoculum outlet cylinder 45 in the rotating inoculum outlet component to inject compound microbial agents into the treatment tank 10. The rotating inoculum outlet component also includes a spiral-shaped base frame 40 and a half-gear 41. The spiral-shaped base frame 40 is fixedly installed on the side of the arc-shaped connecting plate 21 away from the annular fixed plate 30. The spiral-shaped base frame 40 is slidably connected to a spiral-shaped rack plate 42. Tooth blocks are installed on both sides of the spiral-shaped rack plate 42. The rotating rod 22 moves... A half-gear 41 is fixedly installed in the spiral base frame 40 through the spiral base frame 40, and the half-gear 41 is movably meshed with the spiral rack plate 42. A water-pressing rod 43 is installed at the bottom of the spiral rack plate 42, and an annular water-pressing plate 44 is fixedly installed at the bottom end of the water-pressing rod 43. The annular water-pressing plate 44 is also provided with water-pressing holes. The lifting and lowering movement of the annular water-pressing plate 44 drives the wastewater around the bottom of the treatment tank 10 to flow, thereby improving the flow performance of the wastewater inside the treatment tank 10.

[0026] See Figure 6 , Figure 7 , Figure 10 and Figure 11The rack and pinion plate 42 will drive the annular pressure plate 44 to move downward synchronously through the pressure rod 43. The annular pressure plate 44 will vertically press the wastewater inside the treatment tank 10, causing the wastewater inside the treatment tank 10 to be lifted and mixed with the compound microbial agent, thereby increasing the flow intensity of the wastewater inside the treatment tank 10. The rack and pinion plate 42 will drive the annular pressure plate 44 to move upward synchronously through the pressure rod 43. The annular pressure plate 44 will vertically pull the wastewater inside the treatment tank 10, causing the wastewater inside the treatment tank 10 to be lifted and mixed, thereby tumbling the newly sprayed compound microbial agent and increasing the mixing degree between the compound microbial agent and the wastewater.

[0027] See Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A bacterial liquid ring 57 is installed on the top of the annular top plate 20, and an arc-shaped convection plate 54 is set at the top of the bacterial liquid ring 57. A bacterial discharge tube 45 is fixedly installed on the top of the annular top plate 20 at the top of the arc-shaped connecting plate 21. A piston plate 46 is movably installed at the bottom of the inner part of the bacterial discharge tube 45. A piston rod 47 is installed at the bottom of the piston plate 46, and the bottom end of the piston rod 47 passes through the bacterial discharge tube 45 and is installed at the top of the rack plate 42. An arc-shaped guide tube 51 is fixedly installed between the bottom of the bacterial liquid tube 50 and the bacterial liquid ring 57. The arc-shaped guide tube 51 is an iron structure. 51 connects the bacterial liquid cylinder 50 and the bacterial liquid ring 57. A U-shaped conduit 48 connects the top of the bacterial discharge cylinder 45 to the bacterial liquid ring 57. A spray head 49 is fixedly installed on the top of the bacterial discharge cylinder 45. Both the U-shaped conduit 48 and the spray head 49 are equipped with one-way valves. In this way, when the bacterial discharge cylinder 45 generates negative pressure, the compound microbial agent in the bacterial liquid cylinder 50 can only be drawn into the bacterial discharge cylinder 45 through the U-shaped conduit 48. When the bacterial discharge cylinder 45 generates positive pressure, the compound microbial agent can only be sprayed into the treatment tank 10 through the spray head 49.

[0028] See Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10When the arc-shaped drive rod 24 on the arc-shaped drive plate 23 enters the V-shaped flip groove 35, causing the flip rod 22 to rotate in conjunction with the arc-shaped flip plate 25, the flip rod 22 rotates synchronously, driving the half gear 41 inside the loop-shaped base frame 40 to rotate. The half gear 41 meshes and drives the loop-shaped rack plate 42 to move. The loop-shaped rack plate 42 will reciprocate and rise and fall inside the loop-shaped base frame 40. When the arc-shaped drive rod 24 enters the first V-shaped flip groove 35, the half gear 41 meshes with the loop-shaped rack plate 42 and moves downward. The loop-shaped rack plate 42 will drive the piston plate 46 inside the inoculum outlet 45 to fall through the piston rod 47. At this time, the piston plate 46 will generate negative pressure inside the inoculum outlet 45. The compound microbial agent inside the inoculum container 50 will enter the inoculum outlet 45 through the arc-shaped guide pipe 51, the inoculum ring 57 and the U-shaped conduit 48.

[0029] See Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 When the arc-shaped drive rod 24 enters the second V-shaped overturning groove 35, the half gear 41 will continue to rotate and mesh with the circular rack plate 42 to rise. The circular rack plate 42 will drive the piston plate 46 inside the outlet cylinder 45 to rise through the piston rod 47. At this time, the piston plate 46 will generate positive pressure inside the outlet cylinder 45. The compound microbial agent inside the outlet cylinder 45 will be injected into the treatment tank 10 through the spray head 49. When the compound microbial agent is just injected into the treatment tank 10, the arc-shaped overturning plate 25 will turn the wastewater up from the bottom. The arc-shaped overturning plate 25 will turn the wastewater at the bottom and mix it with the compound microbial agent. The water flow from the overturning will mix the compound microbial agent and the wastewater.

[0030] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9A bacterial liquid cylinder 50 is installed at the top of the treatment tank 10, and a mixing convection assembly is installed at the bottom of the bacterial liquid cylinder 50. The arc-shaped convection plate 54 in the mixing convection assembly, together with the arc-shaped flip plate 25, convects and mixes the injected compound microbial agent with the wastewater around the bottom of the treatment tank 10. The mixing convection assembly also includes an annular convection ring 52. An annular base block 27 is fixedly installed on the top of the annular fixing plate 30. An annular limiting groove 28 is opened on the top of the annular base block 27, and an annular limiting block 29 is slidably connected in the annular limiting groove 28. The annular limiting block 29 is installed... At the bottom of the annular top plate 20, the annular top plate 20 is movable on the top outer periphery of the annular fixed plate 30. The arc-shaped guide pipe 51 is fixedly installed with an annular convection ring 52 on the side near the bacterial liquid cylinder 50. The annular convection ring 52 is evenly provided with several flow holes 53. The annular convection ring 52, together with the flow holes 53, mixes and agitates the wastewater at the top of the treatment tank 10. This can both drive the mixing of bacterial liquid and wastewater and avoid damage to the bacteria in the bacterial liquid. The arc-shaped convection plate 54 is provided with convection holes 55. The top of the bacterial liquid cylinder 50 is equipped with a feed pipe 56 with a rotating cover.

[0031] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 During the entire rotational motion, the annular top plate 20 mixes the churning wastewater and compound microbial agent inside through the annular convection ring 52 on the arc-shaped guide pipe 51. The arc-shaped flipping plates 25 around the bottom of the wastewater pool turn the wastewater over, and the flow formed by the turning of the wastewater interacts with the arc-shaped convection plates 54.

[0032] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9A drive motor 13 is installed at the top of the treatment tank 10 to drive the bacterial liquid cylinder 50 to rotate. During the rotation of the bacterial liquid cylinder 50, a stirring and mixing component is set at the bottom of the rotating rod 63. The stirring and mixing component is equipped with an S-shaped stirring rod 65 to stir the inside of the treatment tank 10. The stirring and mixing component also includes an annular internal gear 60 and a drive gear 61. A connecting rod 62 is fixedly installed on the inner side of the annular fixed plate 30. An annular internal gear 60 is fixedly installed between the connecting rods 62. A rotating plate 64 is fixedly installed at the bottom end of the rotating rod 63. The drive gear 61 is movably connected to the rotating plate 64, and the drive gear 61 is movably meshed with the annular internal gear 60. The S-shaped stirring rod 65 is fixedly installed at the bottom center of the drive gear 61 and moves inside the annular fixed plate 30. When the S-shaped stirring rod 65 rotates inside the treatment tank 10, it rotates, expanding the stirring range at the bottom of the treatment tank 10 and improving the stirring and mixing effect of the compound microbial agent and wastewater.

[0033] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 During the rotation of the bacterial culture cylinder 50, the rotating rod 63 drives the rotating plate 64 to rotate. The drive gear 61 on the rotating plate 64 meshes with the inner ring gear 60 during the rotation, so that the drive gear 61 rotates itself. This, in turn, drives the S-shaped stirring rod 65 at the bottom of the drive gear 61 to rotate and stir when it moves in a ring inside the annular fixed plate 30. This can mix the internal wastewater and also mix the multiple streams of water on the outer periphery.

[0034] Working principle: The rotating cover on the feed pipe 56 is opened, and the compound microbial agent is injected into the bacterial liquid cylinder 50. The drive motor 13 drives the bacterial liquid cylinder 50 to rotate, mixing the compound microbial agent inside and effectively preventing sedimentation and uneven distribution of the compound microbial agent into the treatment tank 10. The bacterial liquid cylinder 50, through the arc-shaped guide pipe 51, drives the annular top plate 20 at the top of the annular fixed plate 30 to rotate slowly and uniformly. The annular top plate 20 achieves stable rotation under the action of the annular limiting ring, annular limiting groove 28, and annular limiting block 29. The annular top plate 20, through the arc-shaped connecting plate 21, drives the arc-shaped flipping plate 25 to rotate at the bottom of the treatment tank 10. When the arc-shaped connecting plate 21... When the arc-shaped drive rod 24 at one end of the arc-shaped drive plate 23 moves into the top of the V-shaped flip groove 35 through the push of the arc-shaped drive plate 23, the arc-shaped drive rod 24 at the other end of the arc-shaped drive plate 23 moves to the bottom of the arc-shaped drive plate 34. During the continuous rotation of the arc-shaped connecting plate 21, the arc-shaped drive rod 24 at the bottom of the arc-shaped drive plate 34 moves along the bottom of the arc-shaped drive plate 34, and the arc-shaped drive rod 24 in the V-shaped flip groove 35 causes the arc-shaped drive plate 23 to flip. The arc-shaped drive plate 23 will drive the outer arc-shaped flip plate 25 to flip synchronously through the flip rod 22. The arc-shaped flip plate 25 will drive the "dead water" around the bottom of the treatment tank 10 to move and convect. When the arc-shaped drive rod 24 on the arc-shaped drive plate 23 enters the V-shaped flip groove 35, causing the flip rod 22 to rotate in conjunction with the arc-shaped flip plate 25, the flip rod 22 rotates synchronously, driving the half gear 41 inside the spiral base frame 40 to rotate. The half gear 41 meshes and drives the spiral rack plate 42 to move. The spiral rack plate 42 will reciprocate and rise and fall inside the spiral base frame 40. When the arc-shaped drive rod 24 enters the first V-shaped flip groove 35, the half gear 41 meshes with the spiral rack plate 42 and moves downward. The spiral rack plate 42 will drive the piston plate 46 inside the inoculum outlet 45 to descend through the piston rod 47. At this time, the piston plate 46 will generate negative pressure inside the inoculum outlet 45. The compound microbial agent inside the inoculum container 50 will enter the inoculum outlet 45 through the arc-shaped guide pipe 51, the inoculum ring 57 and the U-shaped conduit 48. Synchronously, the rack and pinion plate 42 will drive the annular pressure plate 44 to move downward synchronously through the pressure rod 43. The annular pressure plate 44 will vertically press the wastewater inside the treatment tank 10, causing the wastewater inside the treatment tank 10 to be lifted and mixed with the compound microbial agent, thereby increasing the flow intensity of the wastewater inside the treatment tank 10.

[0035] When the arc-shaped drive rod 24 enters the second V-shaped overturning groove 35, the half gear 41 will continue to rotate and mesh with the circular rack plate 42 to rise. The circular rack plate 42 will drive the piston plate 46 inside the outlet cylinder 45 to rise through the piston rod 47. At this time, the piston plate 46 will generate positive pressure inside the outlet cylinder 45. The compound microbial agent inside the outlet cylinder 45 will be injected into the treatment tank 10 through the spray head 49. When the compound microbial agent is just injected into the treatment tank 10, the arc-shaped overturning plate 25 will turn the wastewater up from the bottom. The arc-shaped overturning plate 25 will turn the wastewater at the bottom and mix it with the compound microbial agent. The turning water flow will mix the compound microbial agent and the wastewater. Synchronously, the toothed rack plate 42 will drive the annular pressure plate 44 to move upward synchronously through the pressure rod 43. The annular pressure plate 44 will vertically pull the wastewater inside the treatment tank 10, causing the wastewater inside the treatment tank 10 to be lifted and driven, and the newly sprayed compound microbial agent to be tumbled and driven, thereby improving the mixing degree between the compound microbial agent and the wastewater.

[0036] During the entire rotation process, the annular top plate 20 mixes the churning wastewater and compound microbial agent inside through the annular convection ring 52 on the arc-shaped guide pipe 51. The arc-shaped flipping plate 25 around the bottom of the wastewater pool turns the wastewater over, and the flow formed by the turning of the wastewater interacts with the arc-shaped convection plate 54.

[0037] During the rotation of the bacterial liquid cylinder 50, the rotating rod 63 drives the rotating plate 64 to rotate. The drive gear 61 on the rotating plate 64 meshes with the inner ring gear 60 during the rotation, causing the drive gear 61 to rotate itself. This, in turn, drives the S-shaped stirring rod 65 at the bottom of the drive gear 61 to rotate and stir inside the annular fixed plate 30. This not only mixes the wastewater inside but also mixes it with the impact of multiple water flows on the periphery, greatly improving the contact effect between the compound microbial agent and the wastewater and enhancing the wastewater treatment capacity.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
