Description

Technical Field

[0001] This application relates to water purification technology, specifically to water purification equipment and processes for water plants. Background Technology

[0002] In today's society, the safety and quality of water resources are of paramount importance. Water treatment plants possess certain production equipment capable of completing the entire production process of tap water, ensuring that the water quality meets the requirements for general industrial and domestic water use. Before supplying water to cities, the water must first undergo professional filtration treatment. As a key facility providing domestic and industrial water, the water purification equipment and processes used by water treatment plants directly impact the quality of the water supply. During water treatment, water treatment plants typically remove pollutants (such as suspended solids, organic matter, and heavy metal ions) through a combination of physical, chemical, and biological processes. However, with economic development and increasingly stringent environmental standards, people's requirements for water quality are becoming increasingly stringent, thus placing ever higher demands on the water purification equipment used by water treatment plants.

[0003] However, existing water purification equipment typically adds coagulants at a fixed location, which is not conducive to uniform distribution of the coagulants, requires a lot of stirring, is not conducive to rapid coagulation, and is not very convenient to use. Summary of the Invention

[0004] The purpose of this application is to provide a water purification treatment device and a water purification treatment process for a water plant, wherein the water purification treatment device can uniformly apply chemicals.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a water purification and treatment device for water plants, comprising: A coagulation sedimentation tank, wherein the coagulation sedimentation tank is used for coagulation and sedimentation treatment; A pesticide application assembly includes a mounting frame, a first storage container, a rotary pesticide application tube, and a rotary drive unit. The first storage container is mounted on the mounting frame, and the rotary pesticide application tube is rotatably engaged with the first storage container. The rotary pesticide application tube has at least two pesticide outlets, and the rotary drive unit is connected to the rotary pesticide application tube for driving the rotary pesticide application tube to rotate and apply pesticide. A movable component is provided at the coagulation sedimentation tank to drive the mounting frame to move, thereby rotating and dispensing chemicals while the rotating spraying pipe moves.

[0006] In an optional embodiment, the moving component includes a first driving unit, which includes a driving frame and a first driving mechanism. The first driving mechanism is disposed on the coagulation sedimentation tank and is used to drive the driving frame to move along the X-axis direction. The mounting frame is mounted on the driving frame, and the movement of the driving frame along the X-axis direction causes the spraying component to move along the X-axis direction.

[0007] In an optional embodiment, the moving component further includes a second drive unit, which includes a blade mechanism and a slide bar. The slide bar is disposed on the drive frame along the Y-axis direction. The mounting frame is slidably mounted on the slide bar. The blade mechanism is mounted on the mounting frame. The rotation of the blade mechanism drives the mounting frame to move along the Y-axis direction on the slide bar.

[0008] In an optional implementation, a second storage container is further included, which is connected to the first storage container via a hose; A tube synchronization block is mounted on the drive frame and moves along the Y-axis. The tube synchronization block is fixedly connected to one end of the hose near the first storage container. The tube synchronization block is driven by a second drive mechanism, which drives the tube synchronization block to move along the Y-axis.

[0009] In an optional embodiment, the second storage container is provided with a delivery pump, which delivers liquid to the first storage container through the hose; The first storage container is equipped with a liquid level sensor, which is used to obtain the liquid level depth in the first storage container; The water purification equipment in the water plant also includes a first controller. The first controller is electrically connected to the liquid level sensor and the delivery pump. The first controller controls the start and stop of the delivery pump based on the detection result of the liquid level sensor. When the liquid level in the first storage container is lower than the preset lower limit, the first controller turns on the delivery pump. When the liquid level in the first storage container exceeds the preset upper limit, the first controller turns off the delivery pump.

[0010] In an optional embodiment, the rotary drive unit includes a drive motor and a transmission mechanism. The drive motor is mounted on the mounting bracket, and the output shaft of the drive motor is connected to the rotary spraying pipe through the transmission mechanism. The drive motor rotates and drives the rotary spraying pipe to rotate through the transmission mechanism.

[0011] In an optional embodiment, the connection between the bottom wall of the first storage container and the rotating spray pipe is configured as an arc-shaped wall.

[0012] In an optional embodiment, the mounting frame includes a frame body and a floating plate, the moving component is used to drive the frame body to move, the floating plate is disposed on the frame body, and the first storage container is disposed on the floating plate; The float is equipped with a telescopic rod and a hollowed-out scooping plate. One end of the telescopic rod is attached to the float, and the other end is connected to the scooping plate. The telescopic rod extends and retracts, causing the scooping plate to rise and fall, so that the scooping plate is closer to or further away from the liquid surface of the coagulation sedimentation tank.

[0013] In optional embodiments, it also includes a raw water tank, a pretreatment tank, a filtration tank, and a disinfection tank; The raw water tank and the pretreatment tank are connected by a pipeline. The liquid in the raw water tank is transported to the pretreatment tank. The pretreatment tank is equipped with at least two stages of filtration components and is used to receive the liquid from the raw water tank. The pretreatment tank is connected to the coagulation sedimentation tank via a pipeline, and the liquid in the pretreatment tank is transported to the coagulation sedimentation tank. The coagulation sedimentation tank is connected to the filtration tank via a pipeline. The liquid in the coagulation sedimentation tank is transported to the filtration tank. The filtration tank is equipped with a filter membrane, which is used to filter the liquid in the filtration tank. The filtration tank is connected to the disinfection box via a pipe, and the liquid in the filtration tank is transported to the disinfection box for disinfection.

[0014] Secondly, the present invention provides a water purification treatment process for water plants, the steps of which include: Pretreatment: The raw water in the raw water tank is introduced into the pretreatment tank; in the pretreatment tank, large floating objects and fine suspended solids in the raw water are filtered out, and the filtered raw water enters the coagulation sedimentation tank. Coagulation and sedimentation: In the coagulation and sedimentation tank, particulate matter is separated by gravity; the coagulation agent is sprinkled into the coagulation and sedimentation tank, and the coagulant is mixed with the raw water by stirring to form large flocs. After coagulation, the flocs are allowed to settle under the action of gravity, and the clear water overflows from the top of the coagulation and sedimentation tank into the filtration tank. Filtration: The settled water is further filtered in the filtration tank to reduce the turbidity of the water; Disinfection: The filtered water is introduced into the disinfection tank for disinfection and sterilization, killing microorganisms and removing odors from the water.

[0015] Existing water purification equipment uses fixed-position coagulant addition, which suffers from uneven distribution, reliance on agitation, and hinders rapid coagulation. The water purification equipment for water plants provided in this application features a rotary dosing pipe with at least two outlets. A rotary drive unit drives the rotary dosing pipe for rotary dosing. A moving component moves the mounting frame, rotary dosing pipe, and rotary drive unit, enabling rotary dosing while in motion. This improves agent distribution, reduces reliance on agitation, promotes rapid coagulation, and enhances treatment efficiency. Furthermore, the combination of movement and the dosing component automates and flexibly distributes the agent, simplifying operation, reducing labor intensity, and improving convenience. This equipment also improves coagulation and sedimentation effects, providing a better water quality foundation for subsequent processes, enhancing water supply quality, and meeting water quality requirements.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, in a first aspect, embodiments of this application provide water purification equipment for water plants, including a coagulation sedimentation tank 120, a chemical dispensing assembly 200, and a moving assembly 300.

[0024] The 120 coagulation sedimentation tank is used for coagulation and sedimentation treatment.

[0025] like Figures 3 to 5As shown, the spraying assembly 200 includes a mounting bracket 210, a first storage container 220, a rotating spraying tube 230, and a rotating drive unit 240.

[0026] The first storage container 220 is mounted on the mounting bracket 210. The rotary spraying pipe 230 is rotatably engaged with the first storage container 220. The rotary spraying pipe 230 has at least two spray outlets 231. The rotary drive unit 240 is connected to the rotary spraying pipe 230 for driving the rotary spraying pipe 230 to rotate and spray pesticides. Exemplarily, the first storage container 220 is configured as a box, a can, or other suitable shape.

[0027] The movable component 300 is installed at the coagulation sedimentation tank 120 and is used to drive the mounting frame 210 to move. The movement of the mounting frame 210 drives the rotary dosing pipe 230 and the rotary drive unit 240 to move, so that the rotary dosing pipe 230 rotates and dosing while moving.

[0028] For example, the moving component 300 is configured as a robotic arm. The base of the robotic arm is set on or near the ground of the coagulation sedimentation tank 120. The moving end of the robotic arm is fixedly connected to the mounting frame 210. The movement of the robotic arm drives the mounting frame 210 to move. The movement of the mounting frame 210 drives the rotating dosing pipe 230 and the rotating drive unit 240 to move, so that the rotating dosing pipe 230 rotates and dosing while moving, so as to evenly spread the agent in the coagulation sedimentation tank 120.

[0029] Existing water purification equipment adds coagulants at a fixed location, which is not conducive to uniform distribution of the agent, requires high stirring capacity, and is not conducive to rapid coagulation. In this equipment, the rotary dosing pipe 230 of the dosing assembly 200 has at least two outlets 231, and the rotary drive unit 240 drives its rotation for dosing. Simultaneously, the moving assembly 300 moves the mounting frame 210, which in turn moves the rotary dosing pipe 230 and the rotary drive unit 240, allowing the rotary dosing pipe 230 to rotate and dosing during movement. This design allows the agent to be more evenly distributed in the coagulation sedimentation tank 120, effectively improving the uneven distribution of the agent, reducing the dependence on stirring, facilitating rapid coagulation, and improving the overall water purification efficiency.

[0030] By cooperating with the moving component 300 and the spraying component 200, the pesticide application process is automated and flexible. Operators no longer need to manually add pesticide at different locations; they only need to control the operation of the moving component 300 and the spraying component 200 to achieve uniform pesticide application. This greatly simplifies the operation process, reduces labor intensity, and improves the ease of use of the equipment.

[0031] The water purification equipment provided in this application can effectively improve the coagulation and sedimentation treatment effect, and more thoroughly remove pollutants such as suspended solids and organic matter from the water, thereby providing a better water quality foundation for subsequent water treatment processes. Ultimately, it helps to improve the overall water supply quality of the water plant and meet people's increasingly stringent water quality requirements.

[0032] In one embodiment, the discharge directions of at least two discharge ports 231 are at an angle.

[0033] In one embodiment, the upper part of the first storage container 220 is configured as an opening, and a cap 270 is detachably provided at the opening.

[0034] Unlike the technical solution in the above embodiments where the moving component 300 is configured as a robotic arm, such as... Figure 4 As shown, in one embodiment, the moving component 300 includes a first drive unit 310, which includes a drive frame 311 and a first drive mechanism 312.

[0035] The first drive mechanism 312 is installed on the coagulation sedimentation tank 120. The first drive mechanism 312 is used to drive the drive frame 311 to move along the X-axis direction (horizontal direction). The mounting frame 210 is installed on the drive frame 311. The drive frame 311 moves along the X-axis direction, which drives the spraying assembly 200 to move along the X-axis direction, so that the rotating spraying pipe 230 moves back and forth along the X-axis direction while rotating and spraying medicine, thereby improving the uniformity of spraying.

[0036] For example, such as Figure 4As shown, the first drive mechanism 312 is configured as a threaded screw telescopic mechanism, which includes a transmission screw 312a, a rotary motor 312b, and an optical shaft 312c. The drive frame 311 is configured as a U-shaped structure, with one end of the drive frame 311 threadedly engaged with the transmission screw 312a and the other end slidingly engaged with the optical shaft 312c. The optical shaft 312c is arranged along the X-axis. The transmission screw 312a is arranged along the X-axis and one end is connected to the output shaft of the rotary motor 312b. The rotary motor 312b is fixedly mounted on the coagulation sedimentation tank 120 by welding, snap-fitting, or bolting. The output shaft of the rotary motor 312b rotates in the forward direction, causing the transmission screw 312a to rotate in the forward direction. The rotation of the transmission screw 312a in the forward direction causes the drive frame 311 to move in the forward direction of the X-axis. The movement of the drive frame 311 causes the mounting frame 210 to move in the forward direction of the X-axis, thereby causing the rotary spraying pipe 230 to move in the forward direction of the X-axis. The output shaft of the rotary motor 312b rotates in the reverse direction, causing the transmission screw 312a to rotate in the reverse direction. The reverse rotation of the transmission screw 312a causes the drive frame 311 to move in the reverse direction along the X-axis. The movement of the drive frame 311 causes the mounting frame 210 to move in the opposite direction along the X-axis, thereby causing the rotary spraying tube 230 to move in the opposite direction along the X-axis. In another embodiment, the first drive mechanism 312 is configured as a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric actuator telescopic mechanism, or a linear motor, etc., and the telescopic direction of the first drive mechanism 312 is parallel to the X-axis direction.

[0037] For example, the rotary motor 312b includes, but is not limited to, a DC motor, an AC motor, a brushless DC motor, a stepper motor, a servo motor, or a switched reluctance motor.

[0038] The first drive mechanism 312 drives the drive frame 311 to move along the X-axis, which in turn causes the mounting frame 210 and the dispensing assembly 200 mounted on the drive frame 311 to reciprocate along the X-axis, while the dispensing pipe 230 rotates to dispense chemicals. This combination of movement and rotation allows the chemicals to be dispensed into the coagulation sedimentation tank 120 from multiple dimensions and positions. Compared to fixed-position dispensing, this greatly increases the coverage and uniformity of the chemicals in the tank, effectively avoiding situations where the local chemical concentration is too high or too low, thereby improving the coagulation and sedimentation effect.

[0039] A more uniform distribution of the reagents helps them to fully contact and react with pollutants in the water. Suspended solids, organic matter, and other pollutants can react more evenly with the coagulant through coagulation and sedimentation, allowing these pollutants to be removed more effectively. This improves the overall water purification effect and provides a higher quality water source for subsequent water treatment processes.

[0040] During use, the operating parameters of the first drive mechanism 312, such as the moving speed and reciprocating stroke, can be flexibly adjusted according to the actual size and treatment scale of the coagulation sedimentation tank 120 to adapt to the water purification treatment needs of water plants of different sizes. At the same time, this structure also facilitates the adjustment of the movement mode and dosage of the dosing component 200 according to different water quality conditions, improving the applicability and flexibility of the equipment.

[0041] like Figures 4 to 7 As shown, in one embodiment, the moving component 300 further includes a second drive unit 320, which includes a paddle mechanism 321 and a slide bar 322.

[0042] like Figure 4 As shown, the slide bar 322 is mounted on the drive frame 311 along the Y-axis (horizontal direction and perpendicular to the X-axis direction), and the mounting frame 210 is slidably mounted on the slide bar 322, so that the mounting frame 210 can slide along the Y-axis direction.

[0043] like Figure 6 and Figure 7 As shown, the blade mechanism 321 is mounted on the mounting bracket 210. The rotation of the blade mechanism 321 drives the mounting bracket 210 to move along the Y-axis direction on the slide rod 322.

[0044] For example, during use, the rotating spray pipe 230 is also located below the water surface, and the paddle mechanism 321 is also located below the water surface. The paddle mechanism 321 includes a paddle motor and paddle blades. The paddle motor is fixedly mounted on the mounting frame 210 away from the first storage container 220 by welding, snap-fitting, or bolting. At least two paddle blades are fixedly mounted on the output shaft of the paddle motor. The rotation of the paddle motor output shaft drives the paddle blades to rotate. During the rotation of the paddle blades, the liquid provides resistance to the paddle blades, and the paddle blades push against the paddle motor and the mounting frame 210, thereby driving the mounting frame 210 to move on the slide bar 322. The forward rotation of the paddle motor drives the paddle blades to rotate in the forward direction, and the forward rotation of the paddle blades drives the mounting frame 210 to move along the Y-axis in the forward direction on the slide bar 322. The reverse rotation of the paddle motor drives the paddle blades to rotate in the reverse direction, and the reverse rotation of the paddle blades drives the mounting frame 210 to move along the Y-axis in the reverse direction on the slide bar 322. The rotation of the paddle blades can improve the mixing efficiency of the agent.

[0045] For example, the blade motor includes, but is not limited to, DC motors, AC motors, brushless DC motors, stepper motors, servo motors, or switched reluctance motors.

[0046] Unlike the above embodiment where the second drive unit 320 includes a blade mechanism 321 and a slide bar 322, in another embodiment, the second drive unit 320 is configured as a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric actuator telescopic mechanism, a threaded screw telescopic mechanism, or a linear motor, etc.

[0047] The first drive unit 310 drives the dosing assembly 200 to move along the X-axis, and the second drive unit 320 drives the dosing assembly 200 to move along the Y-axis. The two work together to allow the dosing assembly 200 to move flexibly on the two-dimensional plane of the coagulation sedimentation tank 120. This multi-dimensional movement allows the rotating dosing pipe 230 to operate over a wider area, evenly distributing the agent to various locations within the tank, greatly improving the uniformity of dosing, avoiding localized agent accumulation or insufficiency, and thus enhancing the coagulation and sedimentation effect.

[0048] like Figure 2 As shown, in one embodiment, the water purification treatment equipment of the water plant further includes a second storage container 400, which is connected to a first storage container 220 via a hose 410. The second storage container 400 stores a reagent, and the reagent in the second storage container 400 is transported to the first storage container 220 via the hose 410 to replenish the reagent in the first storage container 220.

[0049] For example, the second storage container 400 is configured as a box, can, or other suitable shape.

[0050] A tube synchronization block 510 is mounted on the drive frame 311 along the Y-axis direction. The tube synchronization block 510 is fixedly connected to one end of the hose 410 near the first storage container 220. The tube synchronization block 510 is driven by a second drive mechanism 520, which is used to drive the tube synchronization block 510 to move along the Y-axis direction.

[0051] During use, when the mounting bracket 210 moves on the slide bar 322, the end of the first storage container 220 along the hose 410 near the first storage container 220 may be squeezed by the first storage container 220 and the drive bracket 311, which may easily damage the hose 410. Therefore, when the mounting bracket 210 moves on the slide bar 322, the second drive mechanism 520 actively drives the tube body synchronization block 510 to move, so that the tube body synchronization block 510 (and the end of the hose 410 near the first storage container 220) moves with the mounting bracket 210, thereby ensuring that the end of the hose 410 near the first storage container 220 always maintains a preset distance from the first storage container 220. The preset distance can be set according to the actual needs of the project.

[0052] For example, the second drive mechanism 520 includes a synchronous lead screw 521 and a synchronous motor 522. The synchronous motor 522 is fixedly mounted on the drive frame 311 by welding, snap-fitting, or bolting. The output shaft of the synchronous motor 522 is fixedly connected to the synchronous lead screw 521. The tube body synchronous block 510 is threadedly engaged with the synchronous lead screw 521. The drive frame 311 is provided with a sliding groove, and the tube body synchronous block 510 is slidably engaged with the groove wall of the sliding groove. The groove wall is used to restrict the rotation of the tube body synchronous block 510. The synchronous lead screw 521 is disposed in the sliding groove along the Y-axis direction.

[0053] During operation, the output shaft of the synchronous motor 522 rotates in the forward direction, driving the synchronous screw 521 to rotate in the forward direction. The rotation of the synchronous screw 521 in the forward direction causes the tube body synchronous block 510 to move along the positive Y-axis. The output shaft of the synchronous motor 522 rotates in the reverse direction, driving the synchronous screw 521 to rotate in the reverse direction. The rotation of the synchronous screw 521 in the reverse direction causes the tube body synchronous block 510 to move in the opposite Y-axis direction.

[0054] For example, the synchronous motor 522 includes, but is not limited to, DC motors, AC motors, brushless DC motors, stepper motors, servo motors, or switched reluctance motors.

[0055] In another embodiment, the second drive mechanism 520 is configured as a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric actuator telescopic mechanism, or a linear motor, etc.

[0056] In one embodiment, a delivery pump is provided in the second storage container 400, which delivers liquid to the first storage container 220 through a hose 410.

[0057] like Figure 6 As shown, a liquid level sensor 420 is provided in the first storage container 220, and the liquid level sensor 420 is used to obtain the liquid level depth in the first storage container 220.

[0058] The water purification equipment in the water plant also includes a first controller. The first controller is electrically connected to the liquid level sensor 420 and the transfer pump. The first controller controls the start and stop of the transfer pump based on the detection result of the liquid level sensor 420. When the liquid level in the first storage container 220 is lower than the preset lower limit, the first controller turns on the transfer pump. When the liquid level in the first storage container 220 exceeds the preset upper limit, the first controller turns off the transfer pump.

[0059] For example, the liquid level sensor is based on the principle of ultrasonic ranging. It emits ultrasonic waves, receives the reflected waves, calculates the liquid level depth in the first storage container 220, and converts the result into an electrical signal to be transmitted to the first controller.

[0060] For example, the preset lower liquid level value and the preset upper liquid level value can be set according to actual needs.

[0061] For example, the first controller includes, but is not limited to: a programmable logic controller (PLC), a numerical control device (NC), a process controller, a distributed control system (DCS), a supervisory control and data acquisition system (SCADA), a programmable automation controller (PAC), etc.

[0062] like Figure 5 and Figure 6 As shown, in one embodiment, the rotary drive unit 240 includes a drive motor 241 and a transmission mechanism 242. The drive motor 241 is fixedly mounted on the mounting bracket 210 by means of welding, snap-fitting, or bolting. The output shaft of the drive motor 241 is connected to the rotary spraying pipe 230 through the transmission mechanism 242. The rotation of the drive motor 241 drives the rotary spraying pipe 230 to rotate through the transmission mechanism 242.

[0063] For example, the drive motor 241 includes, but is not limited to, a DC motor, an AC motor, a brushless DC motor, a stepper motor, a servo motor, or a switched reluctance motor.

[0064] like Figure 5 and Figure 6 As shown, exemplarily, the transmission mechanism 242 includes a transmission gear ring 242a and a transmission gear 242b. The transmission gear ring 242a is sleeved on the outer circumferential surface of the rotating spraying tube 230. The transmission gear ring 242a and the rotating spraying tube 230 are fixedly connected by means of adhesive bonding, welding, bolting, riveting, or integral molding.

[0065] The output shaft of the drive motor 241 is fixedly connected to the transmission gear 242b. The rotation of the drive motor 241 drives the transmission gear 242b and the transmission gear ring 242a to rotate, thereby driving the rotary spraying pipe 230 to rotate and spray pesticides.

[0066] Unlike the above embodiment where the transmission mechanism 242 includes a transmission gear ring 242a and a transmission gear 242b, in another embodiment, the transmission mechanism 242 is configured as a sprocket transmission mechanism or a pulley transmission mechanism.

[0067] like Figure 6 and Figure 8As shown, in one embodiment, the connection between the bottom wall of the first storage container 220 and the rotary spraying pipe 230 is provided as an arc-shaped wall 221, which can gather the medicine in the first storage container 220 to the inlet of the rotary spraying pipe 230.

[0068] In one embodiment, the rotary spray pipe 230 is connected to a spray pump, which is capable of pressurizing and pumping the pesticide.

[0069] like Figure 3 As shown, in one embodiment, the mounting frame 210 includes a frame body 211 and a floating plate 212. The floating plate 212 is disposed on the frame body 211. Exemplarily, the floating plate 212 is fixedly connected to the frame body 211 by means of adhesive, snap-fit, welding, bolt connection or integral molding.

[0070] The first storage container 220 is fixedly mounted on the floating plate 212 by means of adhesive, snap-fit, welding or bolt connection.

[0071] The paddle mechanism 321 of the moving component 300 is used to drive the frame 211 to move, and the frame 211 is slidably engaged with the slide bar 322.

[0072] like Figure 5 and Figure 7 As shown, a telescopic rod 260 and a hollowed-out scooping plate 250 are provided on the float plate 212. One end of the telescopic rod 260 is set on the float plate 212. The movement of the float plate 212 drives the telescopic rod 260 to move. The other end of the telescopic rod 260 is connected to the scooping plate 250. The extension and retraction of the telescopic rod 260 drives the scooping plate 250 to rise and fall, so that the scooping plate 250 is close to or away from the liquid surface of the coagulation sedimentation tank 120.

[0073] For example, initially, the telescopic rod 260 and the scooping plate 250 are located in the water, with the scooping plate 250 and the telescopic rod 260 distributed sequentially along the direction of gravity. The telescopic rod 260 is vertically positioned. When the telescopic rod 260 extends, it causes the scooping plate 250 to move upward, thus extending the scooping plate 250 out of the water surface, thereby achieving the scooping of debris in the water. The movement of the float 212 causes the telescopic rod 260 and the scooping plate 250 to move, achieving the scooping of debris from the entire pond and reducing the impact of external impurities on coagulation and sedimentation.

[0074] For example, the telescopic rod 260 includes, but is not limited to, a hydraulic telescopic mechanism, a waterproof pneumatic telescopic mechanism, a waterproof electric actuator telescopic mechanism, a threaded screw telescopic mechanism, or a waterproof linear motor.

[0075] like Figure 1 As shown, in one embodiment, the water purification equipment for the water plant also includes a raw water tank 100, a pretreatment tank 110, a filtration tank 130, and a disinfection tank 140.

[0076] Raw water tank 100 and pretreatment tank 110 are connected by pipelines. Liquid in raw water tank 100 is transported to pretreatment tank 110, which receives the liquid from raw water tank 100. Figure 1 As shown, the pretreatment tank 110 is equipped with at least two stages of filter components 600. Along the water flow direction, the diameter of the filter holes of the filter components 600 gradually decreases, thereby enabling the filtering of smaller diameter impurities step by step and reducing the load on subsequent treatment.

[0077] For example, the filter assembly 600 forms a filter grid, and the diameter of the filter holes in the filter grid gradually decreases along the water flow direction.

[0078] The pretreatment tank 110 is connected to the coagulation sedimentation tank 120 through a pipeline, and the liquid in the pretreatment tank 110 is transported to the coagulation sedimentation tank 120.

[0079] For example, a sludge scraper (single-beam type) is installed at the bottom of the coagulation sedimentation tank 120, and an agitator is installed inside. The sludge scraper scrapes the sludge settled at the bottom of the coagulation sedimentation tank 120 to the sludge discharge port of the coagulation sedimentation tank 120 for discharge, avoiding sludge accumulation that affects the sedimentation effect. The agitator promotes thorough mixing of the coagulant with the raw water, accelerating floc formation.

[0080] The coagulation sedimentation tank 120 is connected to the filter tank 130 via a pipeline. The liquid in the coagulation sedimentation tank 120 is transported to the filter tank 130, which is equipped with a filter membrane, such as a PVDF ultrafiltration membrane, for filtering the liquid in the filter tank 130. Exemplarily, the filter membrane in the filter tank 130 is also equipped with a backwashing system. The ultrafiltration membrane removes fine suspended solids and colloids from the water, and the backwashing system periodically cleans contaminants from the membrane surface.

[0081] The filter tank 130 is connected to the disinfection box 140 through a pipe, and the liquid in the filter tank 130 is transported to the disinfection box 140 for disinfection.

[0082] For example, the disinfection tank 140 is equipped with a chlorine dioxide generator and an ultraviolet lamp for disinfection and sterilization. The chlorine dioxide generator and the ultraviolet lamp work together to disinfect, kill bacteria and viruses in the water, and remove odors.

[0083] Raw water enters the pretreatment tank 110 from the raw water tank 100. After impurities are removed by the filter components 600 in stages, the raw water flows into the coagulation sedimentation tank 120. After the coagulant is added, the mixer is started to mix and form flocs for static sedimentation. The sludge scraper continuously removes the bottom sludge. After sedimentation, the clear water enters the filter tank 130 and is filtered through the filter membrane. The backwashing system is started regularly to clean the filter membrane. After filtration, the clear water enters the disinfection tank 140, where the chlorine dioxide generator and ultraviolet lamp work together to disinfect. After disinfection, the water meets the discharge standards. The grid blockage of the filter components 600 is checked regularly, the membrane flux is monitored, and the disinfection effect is tested. Control principles and methods: The water level in the pretreatment tank 110 is monitored by a liquid level height sensor. When the water level exceeds the warning level, the operating frequency of the filter components 600 is increased. The sludge interface in the coagulation sedimentation tank 120 is monitored by a sludge interface meter. When the sludge thickness exceeds 0.5m, the sludge scraper is started. The filter membrane flux is monitored by a flow sensor. When it is below the threshold, backwashing is started. The disinfection effect is monitored by a residual chlorine detector. When the residual chlorine is below the threshold, the chlorine dioxide dosage is adjusted.

[0084] Secondly, embodiments of this application also provide a water purification process for water plants, the steps of which include: Pretreatment: The raw water in the raw water tank 100 is introduced into the pretreatment tank 110; in the pretreatment tank 110, the raw water is filtered by the filter assembly 600 to remove large floating objects and fine suspended solids. The filtered raw water then enters the coagulation sedimentation tank 120.

[0085] Coagulation and sedimentation: In the coagulation sedimentation tank 120, inorganic particles such as sand and gravel are separated by gravity; the coagulation agent is sprinkled into the coagulation sedimentation tank 120, and the coagulant is mixed with the raw water by stirring to form large flocs. After coagulation, the flocs are allowed to settle under gravity, and the clear water overflows from the top of the coagulation sedimentation tank 120 into the filter tank 130.

[0086] Filtration: The settled water is further filtered in filter tank 130 to reduce the turbidity of the water; Disinfection: The filtered clean water is introduced into the disinfection tank 140 for disinfection and sterilization, killing microorganisms in the water and removing odors. The disinfected water is then delivered to the water supply system.

[0087] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
