Description

Technical Field

[0001] This invention relates to the field of ecological and environmental technology, specifically to a pollution cleaning device and method for ecological and environmental protection. Background Technology

[0002] Ecological river management refers to activities within the land control line of a river channel that, while meeting the basic functions of the river such as flood control, drainage, and water diversion, promote the restoration of the river's aquatic ecosystem through artificial restoration measures, and build a healthy and stable river aquatic ecosystem. Based on the protection of the river aquatic ecosystem, it usually involves sewage treatment and cleaning processes.

[0003] In existing technologies, wastewater treatment typically involves adding flocculants to the wastewater. These flocculants utilize charge neutralization, adsorption bridging, and entrapment to destabilize dispersed suspended particles and cause them to aggregate into flocs with certain settling properties, thus creating favorable conditions for subsequent solid-liquid separation. However, in practical applications, the suspended particles in the wastewater have a wide particle size distribution, and the flocculation reaction between particles of different sizes and flocculants varies. Specifically, fine-sized impurities... Larger particles have a larger specific surface area and a higher probability of contact with flocculants. Under constant dosage conditions, they are prone to over-flocculation, resulting in a large amount of loose scum. This may increase the load on subsequent scum treatment and lead to an increase in the concentration of suspended solids in the effluent. On the other hand, coarse-sized impurity particles have a relatively small specific surface area and lower mass transfer efficiency with flocculants. This can lead to insufficient adsorption of the flocculants and difficulty in forming dense, well-settling flocs. This may result in poor solid-liquid separation and affect the efficiency and effectiveness of wastewater treatment to some extent. Summary of the Invention

[0006] Preferably, the separation component includes a conical block slidably connected to the top of the inner wall of the reaction cylinder, a first pressure rod symmetrically connected to the outer wall of the conical block, a connecting block symmetrically connected between the two sets of first pressure rods on the outer wall of the conical block, and the bottom end of the connecting block being connected to the reaction cylinder via a reset spring.

[0007] Preferably, a guide ring is slidably connected to the top of the separation cylinder and located on the inner wall of the top of the separation cylinder. A second pressure rod is symmetrically connected to the inner wall of the guide ring, and the bottom end of the guide ring is connected to the separation cylinder through a reset spring.

[0008] Preferably, the transmission assembly includes two sets of rotating rings rotatably connected to the outer wall of the reaction cylinder, and multiple sets of stirring blades are provided between the two sets of rotating rings at a lower position of the reaction cylinder.

[0009] Preferably, one set of the rotating rings has connecting rods symmetrically connected to its outer wall, and the top ends of the two sets of connecting rods are connected to a turntable. A driven gear is connected to the upper surface of the turntable. The driven gear is rotatably connected to the inner wall of the top end of the fixed cylinder. A driving gear meshes with one side of the driven gear. A first motor is connected to the upper surface of the driving gear through an output shaft.

[0010] Preferably, one set of rotating rings is symmetrically connected to a first pressure block at its top end, the bottom end of the first pressure block is provided with a guide slope, the top end of the first pressure rod is flush with the higher position of the lower surface of the first pressure block, and both sets of connecting rods are connected to a second pressure block away from the outer wall of the reaction cylinder, the bottom end of the second pressure block is provided with a guide slope, and the top end of the second pressure rod is flush with the higher position of the lower surface of the second pressure block.

[0011] Preferably, a second motor is installed at the center of the top of the fixed cylinder, and the output end of the second motor extends to the inner wall of the reaction cylinder and is connected to a stirring rod. A mixing rod is symmetrically arranged on the inner wall of the annular cavity between the fixed cylinder and the separation cylinder. The bottom ends of the two sets of mixing rods extend to the outer wall of the bottom end of the fixed cylinder and are connected to a third motor through an output shaft.

[0012] Preferably, the top of the inner wall of the reaction cylinder is provided with a guide plate arranged opposite to each other, and the top inner walls of the annular cavities of the fixed cylinder and the separation cylinder are provided with multiple sets of guide rings.

[0013] Preferably, a float plate is slidably connected to the inner wall of the fixed cylinder, and a micro switch connected to the inner wall of the fixed cylinder is provided above the float plate. Both the reaction cylinder and the inner wall of the fixed cylinder are provided with through-beam photoelectric detection components.

[0014] A method for using a pollution cleaning device for ecological and environmental protection includes the following steps: Wastewater pre-separation: Wastewater to be treated is sent into the separation cylinder through the inlet pipe. The first motor drives the rotating ring and stirring blades to rotate through the active gear and driven gear, so that the wastewater forms a stable swirling field. Centrifugal force is used to achieve pre-separation of impurity particles, so that coarse particles are enriched in the outer peripheral area of ​​the separation cylinder and fine particles are enriched in the central area, thus completing the preliminary classification. S2: Wastewater grading and diversion: The rotating ring synchronously drives the first and second pressure blocks to make circular motions. Through the inclined plane squeezing action, the conical block and the diversion ring are driven to move vertically downwards, so that the wastewater containing fine particles in the central area is introduced into the internal cavity of the reaction cylinder, and the wastewater containing coarse particles in the outer peripheral area is introduced into the annular cavity between the fixed cylinder and the separation cylinder, thus achieving graded separation. S3: Flocculant Mixing and Stirring: When the liquid level in the fixed cylinder annular cavity rises to the preset height, the float triggers a micro switch and sends a signal to the control system. The control system shuts down the first motor and starts the second and third motors, which drive the stirring rod and mixing rod to rotate respectively. At the same time, a pre-prepared flocculant solution is quantitatively added to the two cavities through a flexible conveying pipeline, allowing the agent to mix quickly and evenly with the sewage, and performing targeted flocculation treatment on coarse and fine particles, avoiding over-flocculation and insufficient reaction, and improving agent utilization and treatment effect; S4: Floc status detection: The floc formation status in the two chambers is detected in real time by a through-beam photoelectric detection device. When the floc aggregates block the infrared beam and cause the electrical signal to be interrupted, the control system determines that the flocs meet the standard and opens the electric control valve of the corresponding drain pipe to discharge the treated sewage to the subsequent treatment unit. S5: Cyclic Operation Control: After all the sewage in the fixed cylinder and reaction cylinder is discharged, the control system closes the control valve and transports the sewage to be treated through the inlet pipe again. The device automatically enters the next sewage treatment cycle and continues to treat the sewage.

[0015] In summary, the present invention has the following main beneficial effects: 1. This invention utilizes a centrifugal force field generated by a stable swirling flow field driven by a stirring blade. Based on the density differences of particles of different sizes, it achieves preliminary classification and enrichment of coarse and fine impurities. This causes coarse particles to migrate to the outer periphery of the separation cylinder, while fine particles are enriched in the central area of ​​the separation cylinder, laying the foundation for subsequent differentiated treatment. Then, through the inclined surfaces set on the first and second pressing blocks, the conical block and the guide ring are simultaneously driven to move vertically downward while the stirring blade rotates. This guides the wastewater enriched with particles of different sizes to the internal cavity of the reaction cylinder and the annular cavity of the fixed cylinder, respectively, realizing the physical separation of coarse and fine particles in the wastewater. To a certain extent, this reduces the problem of excessive flocculation and loose scum caused by the large specific surface area of ​​fine particles, and avoids the problem of insufficient adsorption of reagents and difficulty in floc formation caused by insufficient mass transfer contact efficiency of coarse particles. This improves the utilization efficiency of flocculants, reduces the operating cost of wastewater treatment reagents, and reduces the additional load of scum treatment, providing good conditions for subsequent solid-liquid separation operations and improving the efficiency of wastewater treatment. 2. This invention uses a float plate and a micro switch to detect the liquid level in the annular cavity of the fixed cylinder. When the liquid level reaches the preset value, the first motor shuts off, and the second and third motors start simultaneously to uniformly mix the flocculant and wastewater. The floc formation status is monitored in real time by a through-beam photoelectric detection component. When the floc aggregates reach the preset treatment requirements, the corresponding electric control valve is automatically opened to drain the wastewater. The operation is simple and convenient, and it significantly improves the wastewater treatment capacity per unit time to a certain extent. Attached Figure Description

[0018] A type of pollution control equipment for ecological and environmental protection, such as Figures 1-10 As shown, the device includes a fixed cylinder 1, a separation cylinder 2 coaxially arranged inside the fixed cylinder 1, a reaction cylinder 3 coaxially arranged at the center of the inner wall of the separation cylinder 2, and an annular cavity between the fixed cylinder 1 and the separation cylinder 2. Through the arrangement of the reaction cylinder 3 and the annular cavity, suspended impurities of different sizes can be separated. The bottom ends of the annular cavity and the reaction cylinder 3 are both connected to a drain pipe 11 extending to the outside of the fixed cylinder 1. The wastewater after flocculation can be discharged through the drain pipe 11. The top ends of the separation cylinder 2 and the reaction cylinder 3 are equipped with separation components for classifying suspended impurities in the wastewater. The outer wall of the reaction cylinder 3 is equipped with a transmission component for driving the separation components.

[0019] See Figure 3 , Figure 6 , Figure 8 , Figure 10 It is known that the separation component includes a conical block 51 slidably connected to the top of the inner wall of the reaction cylinder 3. The conical block 51 can guide the wastewater containing fine-diameter impurities in the central area of ​​the separation cylinder 2 to flow into the internal cavity of the reaction cylinder 3. The outer wall of the conical block 51 is symmetrically connected to a first pressure rod 53. The outer wall of the conical block 51 is symmetrically connected to a connecting block 52 between the two sets of first pressure rods 53. The bottom end of the connecting block 52 is connected to the reaction cylinder 3 through a reset spring. The first pressure rod 53 can drive the conical block 51 to move vertically downward. When the first pressure rod 53 separates from the first pressure block 44, it can be reset under the elastic action of the reset spring.

[0020] See Figure 3 , Figure 4 , Figure 7 It is known that a guide ring 55 is slidably connected to the top of the separation cylinder 2 and located on the inner wall of the top of the separation cylinder 2. A second pressure rod 56 is symmetrically connected to the inner wall of the guide ring 55. The guide ring 55 can be driven to move vertically downward in a straight line through the action of the second pressure rod 56, so that the sewage with coarse-diameter impurities in the outer peripheral area can flow into the annular cavity between the fixed cylinder 1 and the separation cylinder 2. The bottom end of the guide ring 55 is connected to the separation cylinder 2 through a reset spring. The guide ring 55 can be reset through the elastic action of the reset spring.

[0021] See Figure 3 , Figure 5 , Figure 6 , Figure 9 It is known that the transmission component includes two sets of rotating rings 41 rotatably connected to the outer wall of the reaction cylinder 3. Between the two sets of rotating rings 41, a number of stirring blades 42 are provided at the lower position of the reaction cylinder 3. By setting the stirring blades 42, circumferential disturbance can be generated in the wastewater to be treated inside the separation cylinder 2, so that the wastewater forms a stable swirling field. The centrifugal force generated by the swirling field is used to achieve the pre-separation of suspended impurities of different particle sizes in the wastewater.

[0022] See Figure 5 , Figure 6 , Figure 9 It can be seen that a set of rotating rings 41 are symmetrically connected to connecting rods 43 on their outer walls. The tops of the two sets of connecting rods 43 are connected to turntables 46. A driven gear 47 is connected to the upper surface of the turntables 46. The driven gear 47 is rotatably connected to the inner wall of the top of the fixed cylinder 1. A driving gear 48 meshes with one side of the driven gear 47. A first motor is connected to the upper surface of the driving gear 48 through an output shaft. The first motor can drive the driving gear 48 to rotate. The driving gear 48 can drive the driven gear 47 to rotate. In turn, the driven gear 47, in conjunction with the turntables 46, can drive the connecting rods 43 to rotate. In turn, the rotating rings 41 can rotate. In turn, the rotating rings 41 can drive the stirring blades 42 to rotate, thus stirring the sewage on the inner wall of the separation cylinder 2.

[0023] See Figure 5 , Figure 6 , Figure 9 It is known that a first pressure block 44 is symmetrically connected to the top of one set of rotating rings 41. The bottom of the first pressure block 44 is provided with a guide slope. The top of the first pressure rod 53 is flush with the higher position of the lower surface of the first pressure block 44. When the first pressure block 44 rotates and contacts the first pressure rod 53, the first pressure rod 53 can be squeezed under the action of the slope of the first pressure block 44, which in turn can drive the cone block 51 to move vertically downward. The two sets of connecting rods 43 are connected to the second pressure block 45 away from the outer wall of the reaction cylinder 3. The bottom of the second pressure block 45 is provided with a guide slope. The top of the second pressure rod 56 is flush with the higher position of the lower surface of the second pressure block 45. When the second pressure block 45 rotates and contacts the second pressure rod 56, the guide plate 54 can be driven to move vertically downward under the action of the slope provided at the bottom of the second pressure block 45, which can separate suspended impurity particles of different sizes.

[0024] See Figure 3 , Figure 4 , Figure 10It is known that a second motor is installed at the center of the top of the fixed cylinder 1, and the output end of the second motor extends to the inner wall of the reaction cylinder 3 and is connected to a stirring rod 31. A mixing rod 12 is symmetrically arranged on the inner wall of the annular cavity between the fixed cylinder 1 and the separation cylinder 2. The bottom ends of the two sets of mixing rods 12 extend to the outer wall of the bottom end of the fixed cylinder 1 and are connected to a third motor through the output shaft. Through the cooperation of the stirring rod 31 and the mixing rod 12, the flocculant and the sewage can be stirred, which facilitates the flocculation of impurity particles in the sewage into clumps, which is convenient for subsequent solid-liquid separation.

[0025] See Figure 4 and Figure 10 It is known that the top of the inner wall of the reaction cylinder 3 is provided with a guide plate 54 arranged opposite to each other, and the top inner walls of the annular cavities of the fixed cylinder 1 and the separation cylinder 2 are provided with multiple sets of guide rings 55. The arrangement of the guide plate 54 and the guide rings 55 can buffer the water flow, reduce the impact of the water flow on the sewage already stored at the bottom of the reaction cylinder 3, prevent unnecessary turbulence from forming in the reaction cylinder 3, and provide a stable hydraulic environment for the subsequent flocculation reaction.

[0026] See Figure 4 It is known that a float plate 13 is slidably connected to the inner wall of the fixed cylinder 1. A micro switch connected to the inner wall of the fixed cylinder 1 is provided above the float plate 13. Under the action of buoyancy, when the float plate 13 contacts the micro switch, it can squeeze the micro switch, thereby facilitating the start of the second motor and the third motor. Both the reaction cylinder 3 and the inner wall of the fixed cylinder 1 are provided with through-beam photoelectric detection components. The through-beam photoelectric detection components include a receiving end and a transmitting end. The floc formation state can be detected in real time through the through-beam photoelectric detection components.

[0027] A method for using a pollution cleaning device for ecological and environmental protection includes the following steps: S1: Wastewater pre-separation: Wastewater to be treated is sent into separation cylinder 2 through the inlet pipe. The first motor drives the rotating ring 41 and stirring blade 42 to rotate through the drive gear 48 and driven gear 47, so that the wastewater forms a stable swirling field. Centrifugal force is used to achieve pre-separation of impurity particles, so that coarse particles are enriched in the outer peripheral area of ​​separation cylinder 2 and fine particles are enriched in the central area, thus completing the preliminary classification. S2: Wastewater grading and diversion: The rotating ring 41 synchronously drives the first pressure block 44 and the second pressure block 45 to make circular motion. Through the inclined surface squeezing action, the conical block 51 and the diversion ring 55 are driven to move vertically downward, so that the wastewater containing fine particles in the central area is introduced into the internal cavity of the reaction cylinder 3, and the wastewater containing coarse particles in the outer peripheral area is introduced into the annular cavity between the fixed cylinder 1 and the separation cylinder 2, so as to achieve graded separation. S3: Flocculant Mixing and Stirring: When the liquid level in the annular cavity of the fixed cylinder 1 rises to the preset height, the float 13 triggers the micro switch and sends a signal to the control system. The control system shuts down the first motor and starts the second and third motors at the same time, driving the stirring rod 31 and the mixing rod 12 to rotate respectively. At the same time, the pre-prepared flocculant solution is quantitatively added to the two cavities through the flexible conveying pipeline, so that the agent and the sewage are quickly and evenly mixed, and targeted flocculation treatment is carried out on coarse and fine particles to avoid over-flocculation and insufficient reaction, thereby improving the agent utilization rate and treatment effect. S4: Floc status detection: The floc formation status in the two chambers is detected in real time by the through-beam photoelectric detection component. When the floc agglomerates block the infrared beam and cause the electrical signal to be interrupted, the control system determines that the flocs meet the standard and opens the electric control valve of the corresponding drain pipe 11 to discharge the treated sewage to the subsequent treatment unit. S5: Cyclic Operation Control: After all the sewage in the fixed cylinder 1 and the reaction cylinder 3 is discharged, the control system closes the control valve and transports the sewage to be treated through the inlet pipe again. The device automatically enters the next sewage treatment cycle and continues to treat the sewage.

[0028] The working principle of this invention is as follows: When treating sewage, the sewage to be treated is continuously transported to the inside of the separation cylinder 2 through the inlet pipe. Then, the first motor is started, and the output shaft of the first motor drives the drive gear 48 to rotate. The drive gear 48 drives the driven gear 47 meshing with it to rotate synchronously. The driven gear 47 drives the turntable 46 to rotate synchronously. The turntable 46, in conjunction with the connecting rod 43, drives the rotating ring 41 to make coaxial circumferential motion along the outer wall of the reaction cylinder 3. At this time, the stirring blades 42 between the two sets of rotating rings 41 can be driven to rotate synchronously. Multiple sets of stirring blades 42 rotate synchronously with the rotating rings 41, generating circumferential disturbance to the sewage to be treated inside the separation cylinder 2, so that the sewage forms a stable swirling field. The centrifugal force generated by the swirling field is used to achieve the pre-separation of suspended impurities of different particle sizes in the sewage. Under the action of centrifugal force, the denser coarse suspended impurities migrate towards the inner wall of the separation cylinder 2 and accumulate in the outer peripheral area of ​​the separation cylinder 2, while the less dense fine suspended impurities accumulate in the central area of ​​the separation cylinder 2, thereby achieving the preliminary classification and separation of coarse and fine impurities. During the circular motion of the rotating ring 41, it synchronously drives the first pressure block 44 connected to its top to rotate. The bottom end of the first pressure block 44 is provided with an inclined surface. When the first pressure block 44 rotates to contact the top end of the first pressure rod 53 fixedly connected to the outer wall of the conical block 51, under the squeezing action of the inclined surface, the first pressure rod 53 is subjected to a downward axial force, which in turn drives the conical block 51 to move vertically downward in a straight line. Since the liquid level inside the separation cylinder 2 is flush with the top end of the conical block 51, when the conical block 51 moves downward, the wastewater rich in fine-diameter impurities in the central area of ​​the separation cylinder 2 flows into the internal cavity of the reaction cylinder 3 under the guidance of the conical guide surface of the conical block 51. At the same time, the connecting rod 43 synchronously drives the second pressure block 45 to make a circular motion. The bottom end of the second pressure block 45 is also provided with an inclined surface. When the second pressure block 45 rotates to contact the top end of the second pressure rod 56 fixedly connected to the inner wall of the guide ring 55, under the squeezing action of the inclined surface, the second pressure rod 56 is subjected to a downward axial force, which in turn drives the guide ring 55 to make a straight downward motion in the vertical direction. At this time, the sewage with coarse-sized impurity particles in the outer peripheral area flows into the annular cavity between the fixed cylinder 1 and the separation cylinder 2 under the guiding action of the guide ring 55. Through graded guiding, the graded separation of coarse and fine-sized impurity particles is achieved to a certain extent, creating favorable conditions for the subsequent differentiated reaction of impurity particles of different sizes with flocculants. The separated wastewater is guided by the guide plate 54 and the guide ring 55 respectively. The effective volume of the annular cavity of the fixed cylinder 1 is consistent with that of the internal cavity of the reaction cylinder 3. When the wastewater level in the annular cavity of the fixed cylinder 1 rises to the preset height, the float plate 13 moves vertically upward under the action of the buoyancy of the wastewater until the top of the float plate 13 contacts and presses the trigger button of the micro switch fixedly installed on the top of the inner wall of the fixed cylinder 1. After the micro switch is triggered, it sends a liquid level target signal to the control system. After receiving the signal, the control system immediately controls the first motor to stop running and starts the second and third motors at the same time. The second motor drives the stirring rod 31 inside the reaction cylinder 3 to rotate, and the third motor drives the mixing rod 12 inside the annular cavity of the fixed cylinder 1 to rotate, so as to stir and mix the wastewater in the two cavities respectively. Meanwhile, the flocculant solution is quantitatively added to the annular cavity of the fixed cylinder 1 and the internal cavity of the reaction cylinder 3 through the corresponding flexible delivery pipeline. Under the action of the mixing rod 12 and the stirring rod 31, the flocculant solution and the sewage in the corresponding cavity are quickly and evenly mixed, and targeted flocculation reaction treatment is carried out on the suspended impurities of coarse and fine particle sizes. This effectively avoids the problem of excessive flocculation and scum formation caused by the large specific surface area of ​​fine particles, and avoids the problem of insufficient adsorption of the agent and difficulty in floc formation caused by insufficient mass transfer contact efficiency of coarse particles. To a certain extent, it significantly improves the utilization efficiency of flocculant and the flocculation reaction effect. When the suspended impurities and flocculants inside the fixed cylinder 1 and reaction cylinder 3 fully react with the flocculant and form flocs with certain settling properties, the floc formation state is detected in real time by through-beam photoelectric detection components installed at the bottom of the inner walls of the fixed cylinder 1 and reaction cylinder 3. The through-beam photoelectric sensor includes a receiver and a transmitter. The infrared transmitter continuously emits a modulated infrared beam. When the impurities in the wastewater have not formed flocs and no flocs block the infrared beam, the infrared receiver can stably receive the infrared beam and output a normal electrical signal. When the impurities and flocculants fully react with the flocculant and form flocs, the flocs suspend in the water and block the infrared beam, causing the infrared receiver to be unable to receive the infrared beam. At this time, the electrical signal output by the through-beam photoelectric detection component is interrupted. After receiving feedback of the interrupted electrical signal, the control system determines that the floc formation state in the corresponding cavity has reached the preset treatment requirements, and then... The control system opens the electric control valve on the corresponding drain pipe 11. When the floc formation state inside the reaction cylinder 3 meets the standard, the control system opens the electric control valve on the drain pipe 11 connected to the bottom of the reaction cylinder 3, and discharges the wastewater that has completed the flocculation treatment in the reaction cylinder 3 to the subsequent treatment unit through the drain pipe 11. When the floc formation state inside the fixed cylinder 1 meets the standard, the control system opens the electric control valve on the drain pipe 11 connected to the bottom of the fixed cylinder 1, and discharges the wastewater that has completed the flocculation treatment in the fixed cylinder 1 to the subsequent treatment unit through the drain pipe 11, thereby providing good water quality conditions for subsequent solid-liquid separation treatment. After all the wastewater inside the fixed cylinder 1 and the reaction cylinder 3 is discharged, the control system closes each electric control valve and continues to transport the wastewater to be treated into the separation cylinder 2 through the inlet pipe, entering the next wastewater treatment cycle.

10. A method of using a pollution cleaning device for ecological environmental protection, applicable to the pollution cleaning device for ecological environmental protection as described in any one of claims 1-9, the method comprising the following steps: S1: Wastewater pre-separation: The wastewater to be treated is sent into the separation cylinder (2) through the inlet pipe. The first motor drives the rotating ring (41) and stirring blade (42) to rotate through the active gear (48) and driven gear (47), so that the wastewater forms a stable swirling field. Centrifugal force is used to achieve pre-separation of impurity particles, so that coarse particles are enriched in the outer peripheral area of ​​the separation cylinder (2) and fine particles are enriched in the central area, thus completing the preliminary classification. S2: Wastewater graded flow: The rotating ring (41) synchronously drives the first pressure block (44) and the second pressure block (45) to make circular motion. Through the inclined plane squeezing action, the conical block (51) and the flow guide ring (55) are driven to move vertically downward, so that the wastewater containing fine particles in the central area is introduced into the internal cavity of the reaction cylinder (3), and the wastewater containing coarse particles in the outer peripheral area is introduced into the annular cavity between the fixed cylinder (1) and the separation cylinder (2), so as to achieve graded separation. S3: Flocculant mixing and stirring: When the liquid level in the annular cavity of the fixed cylinder (1) rises to the preset height, the float (13) triggers the micro switch and sends a signal to the control system. The control system shuts down the first motor and starts the second and third motors at the same time, driving the stirring rod (31) and mixing rod (12) to rotate respectively. At the same time, the pre-prepared flocculant solution is quantitatively added to the two cavities through the flexible conveying pipeline, so that the agent and sewage are quickly and evenly mixed, and targeted flocculation treatment is carried out on coarse and fine particles to avoid over-flocculation and insufficient reaction, thereby improving the agent utilization rate and treatment effect. S4: Floc status detection: The floc formation status in the two chambers is detected in real time by the through-beam photoelectric detection component. When the floc agglomerates block the infrared beam and cause the electrical signal to be interrupted, the control system determines that the flocs meet the standard and opens the electric control valve of the corresponding drain pipe (11) to discharge the treated sewage to the subsequent treatment unit. S5: Cyclic Operation Control: After all the sewage in the fixed cylinder (1) and the reaction cylinder (3) is discharged, the control system closes the control valve and transports the sewage to be treated through the inlet pipe again. The device automatically enters the next sewage treatment cycle and continues to treat the sewage.
