Description

Technical Field

[0001] This utility model relates to the field of water turbidity treatment technology, and more specifically, to a water turbidity treatment system. Background Technology

[0002] In water quality testing, turbidity is a key physical parameter used to indicate the degree to which suspended matter in water obstructs the transmission of light. Its value directly reflects the number of suspended particles in the water. The degree of turbidity is directly proportional to the turbidity of the water; that is, the more turbid the water, the higher the turbidity; the clearer the water, the lower the turbidity.

[0003] Hydropower station water usage can be divided into production water and domestic water. Production water includes cleaning water for generating units, fire-fighting water for generating units, and fire-fighting water for main transformers, while domestic water is used to ensure the daily life of power station operation and maintenance personnel. According to my country's "Standards for Drinking Water Quality" (GB 5749-2022), the turbidity limit for drinking water is 1 NTU, and even under conditions of limited water source and water purification technology, it should not exceed 3 NTU. The turbidity of water leaving the water treatment plant is usually controlled at around 0.5 NTU. At the same time, to prevent excessive suspended solids in the water from causing scaling in water-using equipment and affecting normal operation, production water for generating units, main transformers, etc., also needs to be treated to reduce turbidity.

[0004] Currently, water turbidity treatment mainly employs physical and chemical methods. Physical treatment utilizes gravity to allow suspended particles in the water to naturally settle to the bottom, thus separating them from the water and reducing turbidity. Chemical treatment involves adding flocculants to alter the surface properties of suspended particles, making them more likely to aggregate into larger, precipitated particles. Physical treatment generally requires no human intervention, while chemical treatment necessitates precise control of the flocculant dosage. In practical applications, accurately controlling the flocculant dosage is crucial for improving the effectiveness of water turbidity treatment. Utility Model Content

[0005] The purpose of this invention is to provide a water turbidity treatment system, which aims to solve the problem of how to accurately control the dosage of flocculant in the existing water turbidity treatment process to improve the water turbidity treatment effect.

The feeding device is installed on the third-stage treatment unit. The first-stage treatment unit, the second-stage treatment unit, the third-stage treatment unit, the feeding device, and the flow meter are all connected to the control terminal.

[0008] The first-stage treatment unit is used to distribute and homogenize the raw water; the second-stage treatment unit is used to perform physical sedimentation treatment on the distributed raw water; and the third-stage treatment unit is used to perform chemical sedimentation treatment on the sedimentation-treated raw water.

[0009] Optionally, the first-stage treatment mechanism includes a first pool body, which is provided with a first-stage inlet and a first-stage outlet. A partition is vertically arranged inside the first pool body, dividing the first pool body into several equalization tanks. The vertical plane of the partition intersects the water flow direction. The partition is provided with water-dividing holes, the two ends of which are respectively connected to the adjacent equalization tanks. The first-stage inlet is used to introduce raw water, and the first-stage outlet is used to introduce the equalized raw water into the second-stage treatment mechanism.

[0010] Optionally, there are at least three partitions, which are spaced apart within the first pool. The height of the water-dividing hole located in the middle of the first pool is greater than the height of the adjacent water-dividing hole.

[0011] Optionally, the second-stage treatment mechanism includes a second tank body, a sedimentation tank body, a second-stage inlet and a second-stage outlet on the sedimentation tank body, the second-stage inlet being connected to the first-stage treatment mechanism, and the second-stage outlet being connected to the third-stage treatment mechanism.

[0012] Optionally, an overflow trough is provided on the side of the sedimentation tank, the height of the baffles on both sides of the sedimentation tank and the overflow trough is greater than the height of the baffle shared in the middle of the sedimentation tank and the overflow trough, a drain outlet is provided on the overflow trough, and a drain valve is provided at the drain outlet.

[0013] Optionally, the sedimentation tank has an inverted trapezoidal shape in its longitudinal cross-section along the water flow direction.

[0014] Optionally, the third-stage treatment mechanism includes a third pool body, which is provided with a third inlet and a third outlet. The third inlet is connected to the second-stage treatment mechanism, and a pumping mechanism is provided at the third outlet.

[0017] Optionally, inspection passages are provided along the sides of the first-level processing unit, the second-level processing unit, and the third-level processing unit, and handrails are provided along the edges of the inspection passages.

[0018] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0019] Multi-stage treatment enhances treatment effectiveness: The system includes a first-stage, second-stage, and third-stage treatment unit, sequentially performing equalization, physical sedimentation, and chemical sedimentation treatments on the raw water. Compared to single-stage treatment, this multi-stage approach more comprehensively and thoroughly removes suspended particles from the water, effectively reducing turbidity. This ensures the treated water better meets the standards for both domestic and industrial water use, guaranteeing that domestic water turbidity complies with the "Standards for Drinking Water Quality" (GB5749-2022) and preventing excessive suspended solids from affecting the operation of water-using equipment in industrial applications.

[0020] Precise control and optimized chemical treatment: A feeding device is installed in the third-stage treatment unit, and all treatment units, feeding devices, and flow meters are connected to the control terminal. The flow meters monitor water flow data in real time, and the control terminal can precisely control the amount of flocculant added based on the water flow conditions and preset treatment requirements. This changes the situation in previous chemical treatment methods where the amount of flocculant added was difficult to control precisely. It avoids poor treatment results caused by insufficient flocculant addition and prevents resource waste and possible secondary pollution caused by excessive addition, thereby significantly improving the effect and efficiency of chemical treatment of water turbidity.

[0021] Real-time monitoring ensures stable processing: Since all key components are connected to the control terminal, the control terminal can obtain data from the first-stage, second-stage, and third-stage treatment units as well as the flow meter in real time. This allows staff to monitor the operating status of the water turbidity treatment system at any time. If any abnormality occurs, such as poor treatment effect of a certain stage of treatment or abnormal flow, it can be detected in time and corresponding measures can be taken to make adjustments, ensuring the stability and continuity of the entire water turbidity treatment process.

Detailed Implementation

[0028] The following is a detailed description of the embodiments, in conjunction with the accompanying drawings.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A water turbidity treatment system includes: a first-stage treatment unit 1, a second-stage treatment unit 2, a third-stage treatment unit 3, a feeding device, and a control terminal. The first-stage treatment unit 1, the second-stage treatment unit 2, and the third-stage treatment unit 3 are sequentially connected. A flow meter is installed at the connection point between the second-stage treatment unit 2 and the first-stage treatment unit 1 and the third-stage treatment unit 3. The feeding device is installed on the third-stage treatment unit 3. The first-stage treatment unit 1, the second-stage treatment unit 2, the third-stage treatment unit 3, the feeding device, and the flow meter are all connected to the control terminal. The first-stage treatment unit 1 is used to perform uniform treatment on the raw water; the second-stage treatment unit 2 is used to perform physical sedimentation treatment on the uniformly treated raw water; and the third-stage treatment unit 3 is used to perform chemical sedimentation treatment on the sedimentation-treated raw water.

[0030] In some embodiments, the first-stage treatment mechanism 1 includes a first tank body with a first-stage inlet 101 and a first-stage outlet 102. A vertically arranged baffle divides the first tank body into several equalization tanks. The vertical plane of the baffle intersects the water flow direction. Dividing holes 103 are provided on the baffle, with both ends of the holes communicating with adjacent equalization tanks. The first-stage inlet 101 is used to introduce raw water; the first-stage outlet 102 is used to introduce the equalized raw water into the second-stage treatment mechanism 2. The first tank body is made of durable materials, such as high-strength concrete or corrosion-resistant steel, to ensure it will not be damaged by water erosion during long-term use. The pipe diameters of the first-stage inlet 101 and the first-stage outlet 102 are rationally designed according to the expected raw water flow rate and velocity to ensure smooth water flow. Based on the characteristics of the raw water and the treatment requirements, the first tank is rationally divided into a suitable number of equalization tanks. The size and shape of each equalization tank are carefully designed to ensure that the water flow is evenly distributed and fully mixed. The size, shape, and number of the water distribution holes 103 are optimized according to the water flow rate, flow velocity, and equalization effect requirements. For example, for raw water with a large flow rate, the diameter of the water distribution holes or the number of water distribution holes can be appropriately increased to ensure that the water flow can pass smoothly through the baffle and achieve effective communication between adjacent equalization tanks. At the same time, the position distribution of the water distribution holes has also been carefully considered to ensure the even distribution of water flow within the equalization tanks. By dividing the first tank into several equalization tanks and setting water distribution holes on the baffles, the raw water can be divided and merged multiple times between the various equalization tanks when flowing through the first-stage treatment mechanism, thereby achieving more thorough mixing and equalization, effectively avoiding water flow deviation and short-circuiting, and improving the uniformity and stability of subsequent treatment.

[0031] In some embodiments, there are at least three baffles, which are spaced apart within the first tank. The height of the water distribution hole 103 located in the middle of the first tank is greater than the height of the adjacent water distribution hole 103. The baffles are made of high-strength, water-corrosion-resistant materials, such as stainless steel or corrosion-resistant plastic. During the construction of the first tank, at least three baffles are precisely installed according to the design spacing, ensuring that the baffles are perpendicular to the bottom surface of the tank and parallel to each other, and are evenly distributed within the first tank. Water distribution holes 103 are opened on each baffle. The height of the water distribution hole located in the middle of the first tank is determined based on hydraulic principles and calculations of the actual raw water flow rate and velocity, ensuring that it is significantly higher than the adjacent water distribution holes. During construction, the height difference of the water distribution holes is strictly controlled, and high-precision measuring tools are used to ensure that the height difference meets the design requirements. At the same time, the size, shape, and number of water distribution holes are rationally designed according to the characteristics of the raw water and treatment requirements. For example, for raw water with a large flow rate and many impurities, the diameter or number of water distribution holes is appropriately increased. The higher water distribution hole in the middle causes the water flow to follow a different path than other water distribution holes when passing through the middle baffle. As the raw water flows through the various equalization tanks, the difference in the height of the water distribution holes creates water flows with different velocities and directions. This causes the water flows to cross and mix more within the equalization tanks, further preventing flow deviation and short-circuiting, and improving the water equalization effect.

[0032] In some embodiments, the second-stage treatment unit 2 includes a second tank body, within which a sedimentation tank 201 is provided. The sedimentation tank 201 has a second-stage inlet and a second-stage outlet. The second-stage inlet communicates with the first-stage treatment unit 1, and the second-stage outlet communicates with the third-stage treatment unit 3. The second tank body is constructed of reinforced concrete, a material with excellent compressive strength and durability, capable of withstanding long-term water pressure and chemical erosion. The tank body is rectangular in shape, with its length determined based on the actual site and treatment volume, generally between 5 and 10 meters; its width between 3 and 5 meters; and its depth between 2 and 3 meters. The bottom of the tank body has a certain slope, ranging from 1% to 3%, facing the drain outlet of the sedimentation tank to facilitate the smooth discharge of settled sludge. The second-stage inlet is located on one side of the second tank body, close to the first-stage treatment unit 1. The inlet has a funnel shape, allowing water to flow more evenly into the second tank body. A flow regulating valve is installed at the inlet, which can be adjusted according to the effluent output of the first-stage treatment unit 1 and the treatment capacity of the second-stage treatment unit 2. The second-stage outlet is located on the other side of the second tank, near the third-stage treatment unit 3. A flow meter is installed at the outlet to monitor the outflow of water and is connected to the control terminal to transmit the flow data to the control terminal in real time for controlling subsequent treatment processes.

[0033] In some embodiments, an overflow trough 202 is provided on the side of the sedimentation tank 201. The height of the side walls of the sedimentation tank 201 and the overflow trough 202 is greater than the height of the shared middle wall between the sedimentation tank 201 and the overflow trough 202. A drain outlet 203 is provided on the overflow trough 202, and a drain valve is provided at the drain outlet 203. The sedimentation tank 201 and the overflow trough 202 are made of high-strength, corrosion-resistant materials, such as stainless steel or corrosion-resistant plastics. These materials can effectively resist the erosion of impurities and chemicals in the water, ensuring long-term stable operation of the equipment. Since the height of the side walls of the sedimentation tank 201 and the overflow trough 202 is greater than the height of the shared middle wall, when the water level in the sedimentation tank 201 rises to a certain level, the water will automatically overflow the shared middle wall and flow into the overflow trough 202, realizing an automatic overflow drainage function. This helps to maintain the stability of the water level in the sedimentation tank 201, ensuring that the sedimentation effect is not affected by water level fluctuations. During the sedimentation process, sludge will accumulate at the bottom of the sedimentation tank 201. By setting up an overflow tank 202, overflowing water is discharged from the overflow tank, preventing sludge from the bottom of the sedimentation tank from flowing out with the water and ensuring the quality of the discharged water. A drain valve is installed at the drain outlet 203 of the overflow tank 202. The drain valve is connected to the control terminal, which allows for flexible control of the drainage speed and volume according to actual conditions. When a rapid reduction in water level is needed, the drain valve can be opened wider; when slow drainage is needed, the drain valve can be closed narrower, improving the controllability of the system.

[0034] In some embodiments, the longitudinal section of the sedimentation tank 201 along the water flow direction is an inverted trapezoidal shape. This inverted trapezoidal shape results in a larger water flow area at the top of the sedimentation tank and a relatively slower water flow velocity, which is conducive to the natural settling of suspended particles. As the water flows downwards, the water flow area gradually decreases, and the water flow velocity gradually increases, enabling the rapid discharge of sludge settled at the bottom, thus improving sedimentation efficiency. This shape guides the water flow to a uniform distribution, avoiding dead zones and eddies, and enhancing the stability of the water flow. Stable water flow helps suspended particles settle evenly within the sedimentation tank, reducing the possibility of particle resuspension and improving the sedimentation effect.

[0035] In some embodiments, the third-stage treatment unit 3 includes a third tank body, which is provided with a third inlet and a third outlet. The third inlet is connected to the second-stage treatment unit 2, and a pumping mechanism 302 is provided at the third outlet. The third inlet is located on the side of the third tank body closer to the second-stage treatment unit 2. The pipe diameter of the inlet is precisely calculated and designed based on the outflow rate and velocity of the second-stage treatment unit 2, and generally a larger pipe diameter, such as a pipe with a diameter of 30-50 cm, is used to ensure that the water flow can smoothly flow into the third tank body. A guide plate is provided at the inlet to evenly distribute the incoming water into the tank body, avoiding the water flow from concentrating and impacting one side of the tank body, which would affect the treatment effect. The third outlet is located on the other side of the third tank body. The pumping mechanism 302 uses a high-efficiency and energy-saving water pump, and its power is reasonably configured according to the volume of the third tank body, the amount of water to be treated, and the required pumping pressure, with a power between 10-30 kilowatts. The suction pipe of the water pump is located at the top of the third tank body, thereby avoiding the removal of sediment at the bottom. Pressure and flow sensors are installed on the outlet pipe to monitor the pressure and flow of the water in real time and feed the data back to the control terminal for precise control of the pumping process.

[0036] In some embodiments, the feeding device includes a bottom feeding mechanism 301 and a moving feeding mechanism 4. The bottom feeding mechanism 301 is located at the bottom of the third tank, and the moving feeding mechanism 4 is located above the third tank. Both the bottom feeding mechanism 301 and the moving feeding mechanism 4 are connected to a control terminal. The bottom feeding mechanism 301 consists of a storage bin, a conveying pipe, and a discharge port. The storage bin is made of a corrosion-resistant material, such as stainless steel, to prevent the flocculant from corroding it. The conveying pipe extends from the bottom of the storage bin and is laid along the bottom of the third tank to the discharge ports at different locations. The discharge ports are distributed at the bottom of the third tank, and the number and location of the discharge ports are rationally arranged according to the size and shape of the third tank to ensure that the flocculant can be evenly added to the water at the bottom of the tank. The control terminal sends instructions to the bottom feeding mechanism 301 based on water turbidity monitoring data and the preset flocculant dosage. The flocculant in the storage bin is slowly released to the bottom of the third tank through the discharge port via the conveying pipe under gravity. Because the flocculant is added at the bottom, it mixes quickly with the water at the bottom, and the water flow gradually diffuses the flocculant throughout the entire tank. The amount of flocculant added is precisely controlled by adjusting the opening degree and duration of the discharge port via a control terminal. A wider opening degree results in a faster dispensing speed; a longer opening time results in a larger dispensing volume. Simultaneously, the control terminal can dynamically adjust the opening parameters of the discharge port based on real-time monitored water turbidity data, achieving precise flocculant addition.

[0037] In some embodiments, the mobile feeding mechanism 4 includes a track 401 and a feeding assembly 402. The track 401 is located above the third tank, and the feeding assembly 402 is slidably connected to the track 401. It is made of high-strength aluminum alloy, which is lightweight, high-strength, and corrosion-resistant, making it suitable for humid working environments. The track spans the top of the third tank, and both ends are securely fixed to the ground or surrounding buildings by sturdy supports. A high-precision slide rail is provided on the inner side of the track 401 to ensure that the feeding assembly 402 can slide smoothly and steadily. The feeding assembly 402 consists of a mobile trolley, a storage tank, a metering pump, and a nozzle. Rollers matching the slide rails of the track 401 are installed at the bottom of the mobile trolley. The rollers are driven by a motor to move on the track, and the forward and reverse rotation of the motor controls the forward and backward movement of the mobile trolley. The storage tank is fixed to the mobile trolley and is used to store flocculant. It is sealed to prevent the flocculant from becoming damp and deteriorating. A metering pump is connected to the bottom of the storage tank, and its flow rate can be precisely adjusted according to the instructions of the control terminal. Spray nozzles are installed at the outlet of the metering pump, with multiple nozzles arranged in a fan shape to ensure that the flocculant is evenly sprayed onto the water surface of the third tank. Based on the turbidity monitoring data of different areas of the third tank and the preset flocculant dosing strategy, the control terminal sends instructions to the mobile feeding mechanism 4. The mobile trolley moves to the designated position on track 401 according to the instructions, the metering pump starts, extracts the flocculant from the storage tank, and after precise metering, sprays it evenly onto the water surface through the nozzles. During the spraying process, the control terminal can adjust the flow rate of the metering pump and the speed of the mobile trolley in real time to achieve precise control of different areas and different dosages. The mobile feeding mechanism 4 can move above the third tank, allowing the flocculant to be evenly sprayed onto the water surface at different locations, avoiding situations where the local flocculant concentration is too high or too low, improving the mixing effect of the flocculant and water, and thus improving the efficiency of flocculation and sedimentation.

[0038] In some embodiments, inspection aisles 5 are provided along the sides of the first-stage processing unit 1, the second-stage processing unit 2, and the third-stage processing unit 3, and handrails 501 are provided along the edges of the inspection aisles 5. The inspection aisles 5 can be made of non-slip, corrosion-resistant, and high-strength materials, such as stainless steel grating or high-strength non-slip plastic sheets. Stainless steel grating has good anti-slip performance and corrosion resistance, and can be used for a long time in humid, watery environments; high-strength non-slip plastic sheets are lightweight, easy to install, and also have good anti-slip effects, effectively preventing inspection personnel from slipping. Handrails 501 can be made of stainless steel pipes. Stainless steel pipes are not only high-strength and can withstand certain external forces, but also corrosion-resistant and not easily rusted, ensuring long-term use in harsh working environments. Providing inspection aisles 5 along the sides of the processing units provides a dedicated walking path for inspection personnel, avoiding potential safety hazards such as slipping and falling that might arise from personnel walking around the equipment at will. The installation of handrail 501 further enhances safety. When inspection personnel walk in the passageway, if they encounter an emergency or the ground is slippery, they can grab the handrail in time to prevent falling and getting injured.
