Description

Technical Field

[0001] This invention relates to the field of water pollution treatment, and more particularly to an apparatus and method for treating environmental water pollution using a microbial method. Background Technology

[0002] Microbial water treatment devices are widely used in environmental water pollution control due to their advantages of being green and environmentally friendly and having stable treatment effects. Currently, existing microbial wastewater treatment devices still have many technical defects in practical use, which restrict the efficiency and quality of wastewater treatment. Traditional mixing structures are mostly single rotation modes, which can only achieve fixed-point rotation and have a limited mixing range, resulting in uneven mixing of wastewater and microbial communities and insufficient biochemical reactions. Meanwhile, conventional aeration devices are mostly fixed installation structures with solidified aeration areas, which cannot fully cover the wastewater body, further reducing the contact efficiency between microorganisms and wastewater and affecting the degradation and purification effect. Furthermore, existing equipment typically uses fixed, static wastewater inlets, resulting in uneven wastewater distribution and easy accumulation and clogging of the mesh by suspended impurities. This not only necessitates frequent shutdowns for cleaning and maintenance, increasing operating costs, but also causes incomplete wastewater filtration and poor water flow, significantly reducing the continuity of wastewater treatment and overall purification efficiency. In summary, existing microbial wastewater treatment devices suffer from insufficient mixing and aeration, and are prone to clogging. Therefore, there is an urgent need to optimize the structure and design a microbial wastewater treatment device that features comprehensive mixing, a wide aeration range, and anti-clogging properties. Summary of the Invention

[0003] Purpose of the Invention: The purpose of this invention is to provide a microbial wastewater treatment device with comprehensive mixing and good mixing effect, solving the technical problems of existing traditional mixing structures that use a single rotation mode, can only rotate at a fixed point, and have a limited mixing range. This effectively improves the problems of uneven mixing of wastewater and microbial communities and insufficient biochemical reactions, significantly improving the reaction efficiency and treatment quality of wastewater biochemical treatment. Another purpose of this invention is to provide a microbial wastewater treatment device with a wide aeration range, comprehensive water coverage, and anti-clogging function. This solves the problems of existing aeration devices being fixed in installation, having a solidified aeration area, and being unable to fully cover the wastewater body, as well as the fixed wastewater inlet structure, uneven wastewater distribution, and easy accumulation of suspended impurities clogging the mesh. This effectively improves the efficiency of full contact between microorganisms and wastewater, enhances the wastewater degradation and purification effect, while avoiding frequent equipment shutdowns for cleaning and maintenance, reducing equipment operation and maintenance costs, ensuring the continuity and stability of wastewater treatment, and comprehensively improving the overall wastewater treatment efficiency and purification effect.

[0012] Furthermore, a drain valve is fixedly installed on the lower front surface of the housing.

[0013] According to another aspect of the present invention, a method for treating environmental water pollution using a microbial approach is provided, comprising the following steps: S1. Wastewater Feeding Filtration and Anti-clogging Cleaning: Wastewater to be treated is injected into the tank through the sewage discharge cylinder at the top of the tank. During the fall of the wastewater, solid-liquid separation is completed through the inclined filter screen. Suspended impurities in the water are intercepted on the surface of the inclined filter screen. The filtered wastewater falls into the treatment chamber at the bottom of the tank. Simultaneously, motor one is started. Motor one drives the double-headed cam to rotate continuously, intermittently squeezing the pressure plate and pushing the L-shaped actuating plate to slide laterally along the guide plate through the guide rod. With the help of spring one, it achieves reciprocating reset. During the movement of the L-shaped actuating plate, it squeezes the U-shaped frame through the trapezoidal squeezing block, causing the U-shaped frame to slide up and down. Through the traction rod, the eccentric disk and the rotating rod are pulled to rotate back and forth, driving multiple knocking rods to move back and forth, intermittently knocking the surface of the inclined filter screen, shaking the intercepted suspended impurities from the slag discharge port into the collection box, realizing dynamic anti-clogging of the inclined filter screen and avoiding the accumulation of impurities and blockage. S2. Microbial Injection and Whole-Area Mixing: Wastewater treatment microbial communities are introduced into the wastewater inside the tank through the microbial injection pipe. Simultaneously, motor two is started, which drives the right-side turntable to rotate, causing multiple stirring rods to revolve with the turntable. At the same time, gear one at the end of the stirring rod meshes with the fixed gear ring, driving the stirring rod to rotate autonomously. Through the combined stirring mode of revolution and rotation, the wastewater and microbial communities inside the tank are stirred in all directions, breaking the limitations of traditional fixed-point stirring, realizing the uniform mixing of wastewater and microorganisms, and ensuring that the biochemical reaction is fully carried out. S3. Dynamic reciprocating aeration: During the rotation of the turntable, the incomplete gear ring rotates synchronously. The incomplete gear ring intermittently meshes with the second gear and the winding wheel to rotate. The winding wheel intermittently pulls the sliding bar through the traction rope. With the reset action of the third spring, the sliding bar, aeration pipe, and diversion pipe move back and forth along the inside of the box. At the same time, the aeration pump is started. The gas output by the aeration pump is distributed to multiple aeration pipes through the hose and diversion pipe, realizing dynamic aeration throughout the entire area, expanding the aeration coverage, covering the sewage body in all directions, improving the activity of microorganisms and the contact efficiency with sewage, and enhancing the degradation effect of pollutants. S4. Clean water discharge: After the sewage inside the tank has fully reacted with the microorganisms and degraded and purified, open the drain valve below the front surface of the tank to discharge the treated clean water from inside the tank, completing a single sewage purification process.

[0014] Beneficial effects: This device is equipped with an inclined filter structure and an automatic sludge removal mechanism, which can complete solid-liquid separation during sewage feeding and continuously intercept suspended impurities in the water. Through the linkage of cam drive, extrusion drive and linkage drive, the sewage is discharged evenly while the knocking structure is driven to intermittently knock the surface of the filter structure, automatically sweeping away the accumulated suspended impurities, realizing dynamic self-cleaning and anti-clogging of the filter structure, and completely solving the problems of impurity accumulation and mesh blockage in traditional fixed filter structures. This device abandons the traditional single fixed-point rotary stirring mode and adopts a composite stirring structure that combines revolution and rotation. It can agitate and stir the sewage inside the tank in all directions without dead angles, greatly expanding the stirring coverage area. It effectively solves the shortcomings of traditional stirring structures, such as limited stirring range and uneven mixing. It can fully and evenly integrate sewage and microbial flora, providing good conditions for water biochemical reactions, promoting the full reaction of pollutants and microorganisms in sewage, and significantly improving the efficiency and purification quality of sewage biochemical treatment. This device relies on stirring power to achieve automatic reciprocating sliding of the aeration structure. Combined with the aeration supply structure, it breaks through the limitations of traditional aeration devices with fixed installation and solidified aeration areas. It can achieve dynamic adjustment of the aeration range, fully covering the sewage inside the tank, effectively improving the uniformity of aeration and oxygen content of the water, greatly activating the activity of microorganisms, improving the contact reaction efficiency between microorganisms and sewage, enhancing the degradation and purification effect of pollutants in the water, and further improving the overall sewage treatment quality.

[0017] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

A guide plate 6 is fixed on the top of the housing 1 and to the right of the cylinder 4. Two guide rods 7 slide on the inner side of the guide plate 6.

An actuating post 10 is fixed to the rear surface of the L-shaped actuating plate 8 and inside the spiral groove 5. A spring 11 is fixed between the L-shaped actuating plate 8 and the guide plate 6 and outside the guide rods 7. An inclined filter screen 12 is fixedly installed inside the upper part of the housing 1; A microbial delivery tube 13 is fixedly connected to the left side of the box 1 and below the left side of the inclined filter screen 12; A through-type slag discharge port 14 is provided on the right side of the housing 1 and on the right side of the inclined filter screen 12. A collection box 15 is fixedly installed on the right side of the box 1 and to the right of the slag discharge port 14, and a cover plate 16 is slidably installed on the top of the collection box 15. An L-shaped bracket 17 is fixed in front of the L-shaped toggle plate 8. A motor 18 is fixed inside the L-shaped bracket 17. A double-headed cam 19 is fixed at the bottom of the output shaft of the motor 18. The outer wall of the double-headed cam 19 is in contact with the right side of the pressure plate 9. In use, the L-shaped bracket 17 provides fixed support for the motor 18. Starting the motor 18 can drive the double-headed cam 19 to rotate continuously. The contour change of the double-headed cam 19 intermittently squeezes the pressure plate 9, providing a power source for the lateral reciprocating sliding of the L-shaped actuating plate 8. The structure is stable and the power transmission is reliable. Wastewater to be treated is injected into the interior of the tank 1 through the sewage discharge cylinder 2 at the top of the tank 1. During the fall of the wastewater, solid-liquid separation is completed by passing through the inclined filter screen 12. Suspended impurities in the water are intercepted on the surface of the inclined filter screen 12, and the filtered wastewater falls into the lower treatment chamber of the tank 1. The synchronously started motor 18 drives the double-headed cam 19 to rotate continuously, intermittently squeezing the pressure plate 9, pushing the L-shaped actuating plate 8 to slide laterally along the guide plate 6 through the guide rod 7, and cooperating with the spring 11 to achieve reciprocating reset. During the movement of the L-shaped actuating plate 8, it squeezes the U-shaped frame 22 through the trapezoidal squeezing block 21, causing the U-shaped frame 22 to slide up and down reciprocally. Through the traction rod 24, the eccentric disk 26 and the rotating rod 25 are pulled to rotate reciprocally, driving multiple striking rods 27 to move back and forth, intermittently striking the surface of the inclined filter screen 12, shaking the intercepted suspended impurities from the slag discharge port 14 into the collection box 15, realizing dynamic anti-clogging of the inclined filter screen 12 and avoiding the accumulation and blockage of impurities.

[0019] An L-shaped pressure plate 20 is fixed to the right side of the upper surface of the L-shaped toggle plate 8, and multiple trapezoidal extrusion blocks 21 are fixed to the inner upper surface of the L-shaped pressure plate 20. A U-shaped frame 22 is slidably installed on the top of the housing 1 and below the L-shaped pressure plate 20. The bottom of the U-shaped frame 22 extends into the interior of the housing 1 and is slidably installed with the housing 1. The top of the U-shaped frame 22 is adapted to the trapezoidal extrusion block 21. Multiple springs 23 are fixed between the U-shaped frame 22 and the housing 1.

Multiple striking rods 27 are fixed on the outer side wall of the rotating rod 25 and located between the two eccentric discs 26. The bottom end of the striking rod 27 contacts the right side of the upper surface of the inclined filter screen 12. In use, the L-shaped actuating plate 8 slides horizontally while driving the L-shaped pressure plate 20 and the trapezoidal extrusion block 21 to move synchronously. The trapezoidal extrusion block 21 extrudes the U-shaped frame 22, and with the elastic reset effect of the spring 23, the U-shaped frame 22 slides up and down. During the sliding process, the traction rod 24 pushes and pulls the eccentric plate 26, driving the rotating rod 25 to rotate back and forth, so that the striking rod 27 continuously and intermittently strikes the surface of the inclined filter screen 12, realizing the automatic cleaning and anti-clogging operation of the filter screen.

[0020] Turntables 28 are embedded on both sides of the box body 1. The turntables 28 are rotatably mounted to the box body 1 via a rotating shaft. Multiple stirring rods 29 are rotatably mounted between the two turntables 28 via a rotating shaft. An L-shaped bracket 30 is fixed on the right side of the box body 1. A motor 31 is fixed on the inner side of the L-shaped bracket 30. The left end of the output shaft of the motor 31 is fixedly connected to the right side of the turntable 28 located on the right side of the box body 1. A fixed gear ring 32 is fixed on the left side of the box body 1. The left end of the central shaft of the stirring rod 29 extends through to the left side of the box body 1 and is fixed with a gear 33. The outer side wall of the gear 33 meshes with the inner side wall of the fixed gear ring 32. In use, motor 2 31 is fixed by L-shaped bracket 2 30. Starting motor 2 31 can drive the right turntable 28 to rotate, causing all stirring rods 29 to revolve around the turntable 28. At the same time, the gear 1 33 at the end of the stirring rod 29 meshes and rolls along the inner side of the fixed gear ring 32, driving the stirring rod 29 to rotate autonomously, forming a composite stirring structure of revolution and rotation, which stirs the sewage inside the tank 1 in all directions, and achieves uniform mixing of sewage and microbial flora.

[0021] On the right side of the turntable 28 located on the right side of the housing 1, there is an incomplete toothed ring 34. A gear 2 35 is engaged below the outer side wall of the incomplete toothed ring 34.

A sliding strip 42 is fixed to the right end of the multiple aeration pipes 41. The sliding strip 42 is slidably installed with the housing 1. Multiple springs 43 are fixed between the sliding strip 42 and the housing 1. Two traction ropes 44 are fixed between the sliding strip 42 and the winding wheel 37. During use, the turntable 28 rotates synchronously, driving the incomplete gear ring 34 to rotate. Through the intermittent meshing of the incomplete gear ring 34 and gear 2 35, the winding wheel 37 is driven to intermittently wind and unwind the traction rope 44. With the tension and reset action of spring 3 43, the sliding bar 42, aeration pipe 41 and diversion pipe 40 slide back and forth along the inside of the box 1. At the same time, the gas output by the aeration pump 38 is diverted through the hose 39 and diversion pipe 40 and then sprayed out from the aeration pipe 41, completing the dynamic aeration operation of the entire area and effectively expanding the aeration coverage.

[0022] A drain valve 36 is fixedly installed on the lower front surface of the housing 1; During use, after the sewage and microbial flora have fully undergone biochemical reaction and pollutant degradation and purification, manually open the drain valve 36 to stably discharge the treated water that meets the standards inside the tank 1. After the drainage is completed, close the drain valve 36 to start the next round of sewage treatment operations and ensure continuous operation of the equipment.

[0023] According to another aspect of the present invention, a method for treating environmental water pollution using a microbial approach is provided, comprising the following steps: S1. Wastewater Feeding Filtration and Anti-clogging Cleaning: Wastewater to be treated is injected into the interior of the tank 1 through the sewage discharge cylinder 2 at the top of the tank 1.

Suspended impurities in the water are intercepted on the surface of the inclined filter screen 12. The filtered wastewater falls into the lower treatment chamber of the tank 1. Simultaneously, the motor 18 is started. The motor 18 drives the double-headed cam 19 to rotate continuously, intermittently squeezing the pressure plate 9, pushing the L-shaped actuating plate 8 to slide laterally along the guide plate 6 through the guide rod 7. With the help of the spring 11, it achieves reciprocating reset. During the movement of the L-shaped actuating plate 8, it squeezes the U-shaped frame 22 through the trapezoidal squeezing block 21, causing the U-shaped frame 22 to slide up and down. Through the traction rod 24, the eccentric disk 26 and the rotating rod 25 are pulled to rotate back and forth, driving multiple striking rods 27 to move back and forth, intermittently striking the surface of the inclined filter screen 12, shaking the intercepted suspended impurities from the slag discharge port 14 into the collection box 15, realizing dynamic anti-clogging of the inclined filter screen 12 and avoiding the accumulation and blockage of impurities. S2. Microbial introduction and full-area mixing: Wastewater treatment microbial flora is introduced into the wastewater inside the tank 1 through the microbial introduction pipe 13. Simultaneously, motor 2 31 is started. Motor 2 31 drives the right turntable 28 to rotate, which drives multiple stirring rods 29 to revolve with the turntable 28. At the same time, the gear 1 33 at the end of the stirring rod 29 meshes with the fixed gear ring 32, driving the stirring rod 29 to rotate autonomously. Through the compound stirring mode of revolution + rotation, the wastewater and microbial flora inside the tank 1 are stirred in all directions, breaking the limitations of traditional fixed-point stirring, realizing the uniform mixing of wastewater and microorganisms, and ensuring that the biochemical reaction is fully carried out. S3. Dynamic reciprocating aeration: During the rotation of the turntable 28, the incomplete gear ring 34 rotates synchronously. The incomplete gear ring 34 intermittently meshes with the second gear 35 and the winding wheel 37 to rotate.

With the reset action of the third spring 43, the sliding bar 42, aeration pipe 41, and diversion pipe 40 slide back and forth along the inside of the box 1. At the same time, the aeration pump 38 is started. The gas output by the aeration pump 38 is distributed to multiple aeration pipes 38 through the hose 39 and the diversion pipe 40 to achieve dynamic aeration throughout the entire area, expand the aeration coverage range, cover the sewage body in all directions, improve the activity of microorganisms and the contact efficiency of sewage, and enhance the degradation effect of pollutants. S4. Clean water discharge: After the sewage inside the tank 1 has fully reacted with the microorganisms and degraded and purified, open the drain valve 36 below the front surface of the tank 1 to discharge the treated clean water from the inside of the tank 1, thus completing a single sewage purification process.

10. A method for treating environmental water pollution using a microbial method, comprising the apparatus for treating environmental water pollution using a microbial method as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Wastewater Feeding Filtration and Anti-clogging Cleaning: The wastewater to be treated is injected into the tank (1) through the sewage discharge cylinder (2) at the top of the tank (1). During the fall of the wastewater, it passes through the inclined filter screen (12) to complete solid-liquid separation. The suspended impurities in the water are intercepted on the surface of the inclined filter screen (12). The filtered wastewater falls into the lower treatment chamber of the tank (1). Simultaneously start the motor (18). The motor (18) drives the double-headed cam (19) to rotate continuously, intermittently squeezing the pressure plate (9) and pushing the L-shaped actuating plate (8) through the guide rod (7) along the guide plate (6). The L-shaped actuating plate (8) slides and reciprocates with the spring (11). During the movement of the L-shaped actuating plate (8), the trapezoidal extrusion block (21) extrudes the U-shaped frame (22), causing the U-shaped frame (22) to slide up and down. The traction rod (24) pulls the eccentric disk (26) and the rotating rod (25) to rotate back and forth, driving multiple striking rods (27) to move back and forth, intermittently striking the surface of the inclined filter screen (12), shaking the intercepted suspended impurities from the slag discharge port (14) into the collection box (15), realizing the dynamic anti-clogging of the inclined filter screen (12) and avoiding the accumulation and blockage of impurities. S2. Microbial introduction and full-area mixing: Wastewater treatment microbial community is introduced into the wastewater inside the tank (1) through the microbial introduction pipe (13), and motor two (31) is started simultaneously. Motor two (31) drives the right turntable (28) to rotate, which drives multiple stirring rods (29) to revolve with the turntable (28). At the same time, the gear one (33) at the end of the stirring rod (29) meshes with the fixed gear ring (32), driving the stirring rod (29) to rotate autonomously. Through the compound stirring mode of revolution + rotation, the wastewater and microbial community inside the tank (1) are stirred in all directions, breaking the limitations of traditional fixed-point stirring, realizing the uniform mixing of wastewater and microorganisms, and ensuring that the biochemical reaction is fully carried out. S3, Dynamic reciprocating aeration: During the rotation of the turntable (28), the incomplete gear ring (34) rotates synchronously. The incomplete gear ring (34) intermittently meshes with the drive gear two (35) and the winding wheel (37) to rotate. The winding wheel (37) intermittently pulls the sliding bar (42) through the traction rope (44). With the reset action of the spring three (43), the sliding bar (42), aeration pipe (41), and diversion pipe (40) slide back and forth along the inside of the box (1). At the same time, the aeration pump (38) is started. The gas output by the aeration pump (38) is distributed to multiple aeration pipes (38) through the hose (39) and diversion pipe (40) and sprayed out, realizing dynamic aeration throughout the entire area, expanding the aeration coverage range, covering the sewage body in all directions, improving the microbial activity and sewage contact efficiency, and strengthening the pollutant degradation effect. S4. Discharge of clean water: After the sewage inside the tank (1) has fully reacted with the microorganisms and degraded and purified, open the drain valve (36) below the front surface of the tank (1) to discharge the treated clean water from the inside of the tank (1) and complete the single sewage purification process.
