Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a wastewater treatment device and process. Background Technology

[0002] Wastewater treatment is a process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. As people's living standards improve, the amount of wastewater generated is also increasing.

[0003] Currently, in the preliminary treatment of wastewater, activated coagulants are usually added to the wastewater tank. Coagulants have surface charge effects and strong adsorption effects, which can bind and coagulate organic or inorganic pollutants in wastewater, causing the pollutants to aggregate and separate from the wastewater, producing solid flocs, and allowing ions in the wastewater to be desorbed. However, the amount of activated coagulant added in the preliminary treatment of wastewater is uncertain, and excessive activated coagulants are often added, which increases the cost of wastewater treatment. In addition, some activated coagulants have low mixing degree with wastewater and are difficult to mix fully to produce solid flocs. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a wastewater treatment device and process.

[0005] The wastewater treatment equipment and process provided in this application adopt the following technical solution:

[0006] A wastewater treatment device includes a treatment tank, a storage tank, a sensor, a feeding component, a mixing component, a linkage component, and a pumping component. The storage tank, which stores coagulant, is connected to the treatment tank, and the treatment tank is used to store wastewater. The sensor is installed inside the storage tank. The feeding component is connected to the storage tank and electrically connected to the sensor. The mixing component is installed inside the treatment tank. The pumping component is installed at the connection between the treatment tank and the storage tank. The linkage component is installed inside the treatment tank, with one end connected to the pumping component and the other end connected to the mixing component. The mixing component is electrically connected to the sensor. The mixing component drives the linkage component to operate the pumping component, causing the coagulant in the storage tank to be pumped into the treatment tank and mixed with the wastewater under the drive of the mixing component. The sensor senses the amount of coagulant being delivered and opens and closes the mixing component, and adds coagulant through the feeding component.

[0007] By adopting the above technical solution, the mixing component drives the linkage component to operate the material extraction component, which can simultaneously extract coagulant from the storage tank and mix the coagulant with the sewage. When the sensing component detects the amount of coagulant in the storage tank, it controls the opening and closing of the mixing component to achieve the function of quantitatively delivering coagulant. This reduces the waste caused by excessive coagulant delivery or the insufficient sewage treatment caused by insufficient delivery. Furthermore, it provides mixing between sewage and coagulant while delivering the coagulant, thereby improving the mixing degree between sewage and coagulant.

[0008] Optionally, the storage tank is further provided with an adjusting component; the adjusting component is located inside the storage tank, and the sensing component is slidably connected to the adjusting component.

[0009] By adopting the above technical solution, the position of the sensing element in the storage tank can be adjusted by the adjusting component to adapt to the amount of coagulant to be added each time it is conveyed, or the amount of coagulant to be added when feeding.

[0010] Optionally, the mixing component includes a mixing section, a driving section, and a rotating section; the driving section is installed outside the processing tank; the rotating section is connected to the output end of the driving section and extends into the processing tank; a plurality of the mixing sections are installed on the rotating section; and the linkage is connected to the rotating section.

[0011] By adopting the above technical solution, when the drive unit drives the rotating unit to rotate, the mixing unit on the rotating shaft rotates accordingly, thereby mixing the sewage and coagulant. The linkage is connected to the rotating shaft, so that when the rotating shaft rotates, it drives the linkage to rotate, and the linkage drives the extraction unit to extract the coagulant. The mixing speed of the coagulant and sewage changes with the rotation speed of the drive unit, so as to further fully mix the sewage and coagulant.

[0012] Optionally, the mixing component further includes a rotating part and a transmission part; the rotating part is movably connected to the inner wall of the treatment tank, the transmission part is installed on the rotating part, and the rotating part is connected to the rotating part through the transmission part; a plurality of the mixing parts are laid on the rotating part.

[0013] By adopting the above technical solution, when the drive unit drives the rotating unit to rotate, the rotating unit drives the linkage and transmission unit to rotate during the rotation process. The linkage rotates to drive the material extraction unit to extract the coagulant, and the transmission unit rotates to drive the rotating unit to rotate. The rotating unit rotates along the inner wall of the treatment tank, thereby driving several mixing units to rotate along the treatment tank. The mixing units on the rotating unit cooperate with each other to ensure that the sewage and coagulant in the treatment tank are fully mixed.

[0014] Optionally, the linkage includes a first linkage part and a second linkage part; the first linkage part is connected to one end of the material extraction part located in the processing pool; the second linkage part is installed on the mixing part, and the first linkage part is connected to the second linkage part.

[0015] By adopting the above technical solution, when the mixing component drives the second linkage part to rotate, the second linkage part drives the first linkage part to rotate, thereby causing the first linkage part to drive the material extraction component to operate, so as to extract the coagulant in the storage tank into the treatment tank.

[0016] Optionally, the diameter of the first linkage part is smaller than the diameter of the second linkage part.

[0017] By adopting the above technical solution, the diameter of the first linkage part is smaller than the diameter of the second linkage part, so that when the second linkage part rotates once, it will drive the first linkage part to rotate more than once, thereby increasing the rotation speed of the material extraction component driven by the first linkage part and improving the material extraction efficiency.

[0018] Optionally, the material extraction component includes a spiral part, an mounting part, and a support part; the support part is installed at the connection between the processing pool and the storage pool, the mounting part is movably connected to the support part, and the mounting part extends through the support part into the processing pool; the mounting part is located at one end of the processing pool and connected to the linkage component; the spiral part is installed on the mounting part.

[0019] By adopting the above technical solution, when the mixing component drives the linkage component to operate, the linkage component is connected to the installation part, causing the installation part to rotate along the support part. During the rotation of the installation part, the spiral part rotates, and the rotation of the spiral part creates a negative pressure at the connection between the treatment tank and the storage tank, thereby drawing the coagulant in the storage tank into the treatment tank to complete the extraction of the coagulant.

[0020] Optionally, the number of spiral sections is at least one.

[0021] By adopting the above technical solution, at least one spiral section is set, which means that multiple sets of spiral sections can be set on the installation section. The more spiral sections there are, the faster the conveying speed of the coagulant can be accelerated, and the more stable the negative pressure material extraction state can be ensured.

[0022] Optionally, a closure is provided at the connection between the processing pool and the storage pool.

[0023] By adopting the above technical solution, the connection between the treatment tank and the storage tank can be closed when the coagulant is not needed, and the closure can be opened when the coagulant needs to be transported, so as to ensure the stability and accuracy of the coagulant transport volume.

[0024] A wastewater treatment process, based on the above-mentioned wastewater treatment equipment, includes the following steps:

[0025] Influent: Wastewater enters the treatment tank;

[0026] Dissolution: The coagulant dissolves into a liquid coagulant;

[0027] Feeding: The dissolved liquid coagulant is conveyed to the storage tank through the feeding device. When the sensor detects that the amount of liquid coagulant is sufficient, feeding is stopped.

[0028] Material extraction: The operation of the mixing unit drives the material extraction unit through the linkage to extract the liquid coagulant into the treatment tank.

[0029] Mixing: During operation, the mixing unit mixes the liquid coagulant extracted by the extraction unit with the wastewater;

[0030] Quantitative: When the sensor detects that the amount of liquid coagulant in the storage tank has decreased to the required conveying amount, it sends an electrical signal to the mixer to stop pumping and mixing, and sends an electrical signal to the feeding unit to replenish the liquid coagulant;

[0031] Discharge: Wastewater is mixed with liquid coagulant to produce solid flocs. After collecting the solid flocs, the treated wastewater is discharged.

[0032] By adopting the above technical solution and the above treatment process, flocculants can be precipitated from the wastewater, and the wastewater and flocculants can be separated, thereby achieving a partial treatment effect of wastewater treatment.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By driving the linkage component through the mixing component, the material extraction component can be operated, which can simultaneously extract coagulant from the storage tank and mix the coagulant with the sewage. When the sensing component detects the amount of coagulant in the storage tank, it controls the opening and closing of the mixing component to achieve the function of quantitative delivery of coagulant. This reduces the waste caused by excessive coagulant delivery or the insufficient sewage treatment caused by insufficient delivery. In addition, it provides mixing of sewage and coagulant at the same time as delivery to improve the mixing degree of sewage and coagulant.

[0035] 2. When the drive unit drives the rotating unit to rotate, the rotating unit drives the linkage and transmission unit to rotate during the rotation process. The linkage rotates to drive the material extraction unit to extract the coagulant, and the transmission unit rotates to drive the rotating unit to rotate. The rotating unit rotates along the inner wall of the treatment tank, thereby driving several mixing units to rotate along the treatment tank. The mixing units on the rotating unit cooperate with each other to ensure that the sewage and coagulant in the treatment tank are fully mixed.

[0036] 3. When the mixing component drives the linkage component to operate, the linkage component connects with the installation part, causing the installation part to rotate along the support part. During the rotation of the installation part, the spiral part rotates, which in turn creates a negative pressure at the connection between the treatment tank and the storage tank, and draws the coagulant in the storage tank into the treatment tank to complete the coagulant extraction.

[0037] 4. The connection between the treatment tank and the storage tank can be closed when coagulant is not needed, and the connection can be opened when coagulant needs to be transported, so as to ensure the stability and accuracy of the coagulant delivery. Attached Figure Description

[0051] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0052] This application discloses a wastewater treatment equipment and process.

[0053] A wastewater treatment device, in one embodiment, refers to Figure 1The system includes a treatment tank 1, a storage tank 2, a sensing element 3, a feeding element 4, a mixing element 5, a linkage element 6, and a pumping element 7. The storage tank 2, which is connected to the treatment tank 1, is used to store wastewater. The storage tank 2 is mainly used to store liquid coagulant. The specific size of the storage tank 2 can be controlled. It can be a cylindrical tank or a square tank. The specific shape and size are not limited here. In this embodiment, the storage tank 2 is a square tank. For example, the internal length and width of the square tank can both be 1m, and the height can be 1m-3m. This makes it easy to calculate the volume of liquid coagulant that can be stored in the internal space, and to calculate the amount of coagulant to be delivered. It also makes it easy to determine whether the delivery amount meets the specified requirements based on the volume change. The treatment tank 1 can be a cylindrical tank. The specific size and treatment space are determined according to the actual needs of the wastewater treatment and the actual available site. They are not limited here. The treatment tank 1 can be connected to a water supply pipe and a drainage pipe. The water supply pipe is used to transport the wastewater to be treated into the treatment tank 1, and the drainage pipe discharges the treated wastewater from the treatment tank 1.

[0054] The connection between the treatment tank 1 and the storage tank 2 can be achieved by having inlet holes on both tanks and connecting the two inlet holes to make them connected, or by setting a connecting component 8 between the treatment tank 1 and the storage tank 2. The connecting component 8 can be a feed pipe, which connects the treatment tank 1 and the storage tank 2. Using a feed pipe allows the treatment tank 1 or the storage tank 2 to be connected even if they are a certain distance apart, which can adapt to the installation environment.

[0055] The sensing element 3 is installed in the storage tank 2. The feeding element 4 is connected to the storage tank 2 and electrically connected to the sensing element 3. The sensing element 3 can be a liquid level sensor, which is used to detect the amount of coagulant used in the storage tank 2. The feeding element 4 can be a feeding pipe and a water pump. The feeding pipe is connected to the external coagulant mixing tank through the water pump. In the coagulant mixing tank, solid coagulant and water are mixed to form liquid coagulant, which is referred to as coagulant below. Then, it is transported to the storage tank 2 through the feeding pipe and the water pump. When the liquid level sensor detects that the amount of coagulant in the storage tank 2 is insufficient, it sends an electrical signal to the water pump. The water pump transports the coagulant that has been mixed in the external coagulant mixing tank to the storage tank 2 through the feeding pipe. When the liquid level sensor detects that the amount of coagulant in the storage tank 2 is sufficient, disconnecting the sent electrical signal or sending a stop delivery electrical signal can stop the water pump from transporting the coagulant.

[0056] The mixing component 5 is installed in the treatment tank 1, and the extraction component 7 is installed at the connection between the treatment tank 1 and the storage tank 2. The mixing component 5 can be a stirring device, which is used to mix the coagulant with the sewage so that the sewage and the coagulant are fully combined. The extraction component 7 can be used to extract the coagulant from the storage tank 2 to the treatment tank 1.

[0057] The linkage 6 is installed in the treatment tank 1, with one end connected to the material extraction component 7 and the other end connected to the mixing component 5. The linkage 6 uses the driving force of the mixing component 5 to mix the coagulant and sewage to drive the material extraction component 7. Thus, when the mixing component 5 is in operation, it will drive the material extraction component 7 through the linkage 6 to operate. No additional drive source is required, thereby reducing the power supply and achieving the effect of energy saving and environmental protection.

[0058] The mixing component 5 is electrically connected to the liquid level sensor. When the liquid level sensor detects that the coagulant dosage is insufficient, it indicates that the coagulant dosage is sufficient. At this time, an electrical signal is sent to the mixing component 5 and the extraction component 7, causing the mixing component 5 to stop mixing and the extraction component 7 to replenish the storage tank 2.

[0059] The mixing component 5 drives the linkage component 6 to operate the material extraction component 7, which can simultaneously extract coagulant from the storage tank 2 and mix the coagulant with the sewage. When the sensing component 3 detects the amount of coagulant in the storage tank 2, it controls the opening and closing of the mixing component 5 to achieve the function of quantitatively delivering coagulant. This reduces the waste caused by excessive coagulant delivery or the insufficient sewage treatment caused by insufficient delivery. At the same time as delivery, it provides mixing between sewage and coagulant to improve the mixing degree between sewage and coagulant.

[0060] Further reference Figure 2 As shown, the storage pool 2 is also provided with an adjusting component 21. The adjusting component 21 is located inside the storage pool 2, and the sensing component 3 is slidably connected to the adjusting component 21. The adjusting component 21 may include a vertical slide rail 211, a lead screw 212, a connecting slider 213, and a throttle 214. The vertical slide rail 211 is fixedly installed inside the storage pool 2. The vertical slide rail 211 can be replaced with a vertical slide groove, which can be directly opened on the inner wall of the storage pool 2. In this embodiment, the vertical slide rail 211 is used as an example.

[0061] The connecting slider 213 can slide along the vertical slide rail 211, and a threaded hole is opened on the connecting slider 213. The lead screw 212 extends into the storage pool 2 through the threaded hole and passes through the connecting slider 213. The handle 214 is installed on the top of the lead screw 212 and is located outside the storage pool 2. The liquid level sensor is installed on the connecting slider 213, and the storage pool 2 can be engraved with scale marks, which indicate the volume.

[0062] Specifically, the user can rotate the screw 212 by turning the handle 214. After the screw 212 rotates, the connecting slider 213 is limited by the vertical slide rail 211 and cannot rotate with the screw 212. Instead, it moves up and down along the vertical slide rail 211 in the direction of the screw 212's rotation, thereby adjusting the position of the liquid level sensor in the storage tank 2 to adjust the required amount of coagulant to be delivered each time and the required amount of feed to be added.

[0063] In some embodiments, reference Figure 3As shown, the mixing component 5 includes a mixing part 51, a driving part 52, and a rotating part 53. The driving part 52 is installed outside the treatment tank 1. The driving part 52 can be a driving motor and a mounting base. The mounting base can be installed on the outer top surface of the treatment tank 1 and is connected to a frame. The driving motor is installed on the mounting base, and the output end of the driving motor faces into the treatment tank 1.

[0064] The rotating part 53 is connected to the output end of the drive part 52 and extends into the treatment tank 1. The rotating part 53 can be a rotating shaft, which is connected to the output end of the drive motor and extends into the treatment tank 1, so that the drive motor can drive the rotating shaft to rotate.

[0065] The mixing unit 51 is installed on the rotating shaft, and the linkage 6 is connected to the rotating shaft. The mixing unit 51 can be a stirring frame or mixing blades. Taking mixing blades as an example, the number of mixing blades is set to several, specifically according to the depth of the treatment tank 1 and the interval between each mixing blade.

[0066] Specifically, when the drive motor drives the rotating shaft to rotate, the mixing blades on the shaft rotate accordingly, thereby causing the mixing blades to agitate and mix the sewage and coagulant. The linkage 6 is connected to the rotating shaft, so that when the rotating shaft rotates, it drives the linkage 6 to rotate. The mixing speed changes with the speed of the drive motor to achieve a thorough and convenient mixing effect.

[0067] Further reference Figure 4 As shown, the mixing component 5 also includes a rotating part 54 and a transmission part 55. The rotating part 54 is movably connected to the inner wall of the treatment tank 1. The rotating part 54 can be an internal gear ring. The outer diameter of the internal gear ring matches the inner diameter of the treatment tank 1. The way to movably connect with the inner wall of the treatment tank 1 is to set an annular slide rail or an annular groove on the inner wall of the treatment tank 1. The internal gear ring is provided with several protrusions, and the protrusions match the annular slide rail or annular groove so that the protrusions can be inserted into the annular slide rail or annular groove. The internal gear ring can then rotate along the annular slide rail or annular groove through the protrusions. Alternatively, the outer wall structure of the internal gear ring can match the annular slide rail or annular groove. The internal gear ring can be embedded in the annular slide rail or annular groove through the outer wall of the internal gear ring, which can also achieve the function of rotating along the annular slide rail or annular groove.

[0068] The transmission part 55 is installed on the rotating part 53. The internal gear ring is connected to the rotating part 53 through the transmission part 55. The rotating part 53 can be a rotating shaft, and the transmission part 55 can be a spur gear. The spur gear is fixedly installed on the rotating shaft, and the spur gear and the internal gear ring are in a meshing state. Therefore, when the rotating shaft rotates, the internal gear ring can be driven to rotate through the spur gear.

[0069] Several mixing sections 51 are evenly laid on the rotating section 54. The mixing section 51 can be a mixing blade or a stirring frame. Taking the stirring frame as an example, several stirring frames are set and evenly installed on the inner toothed ring so that the inner toothed ring can drive several stirring frames to rotate when it rotates. The specific number depends on the size of the stirring frame and the circumference of the inner toothed ring. The angle of the inclined part of the stirring frame is to reduce the water resistance during the rotation.

[0070] Specifically, when the drive motor drives the rotating shaft to rotate, the rotating shaft drives the linkage 6 and the spur gear to rotate during the rotation process. The rotation of the linkage 6 drives the material extraction component 7 to extract the coagulant. The rotation of the spur gear drives the internal gear ring to rotate. The internal gear ring rotates along the inner wall of the treatment tank 1, thereby driving the stirring frame to rotate along the treatment tank 1. In conjunction with the mixing blades on the rotating shaft, the sewage and coagulant in the treatment tank 1 are fully mixed.

[0071] In some embodiments, reference Figure 5 As shown, the material extraction component 7 includes a spiral part 71, an installation part 72, and a support part 73. The support part 73 is installed at the connection between the treatment tank 1 and the storage tank 2. The installation part 72 is movably connected to the support part 73, and the installation part 72 extends through the support part 73 into the treatment tank 1. The support part 73 can be a bearing seat, and the installation part 72 can be a material extraction shaft. Taking the connection between the treatment tank 1 and the storage tank 2 as an example, a connecting part 8, i.e., a feed pipe, is provided. The feed pipe connects the treatment tank 1 and the storage tank 2. Two sets of bearing seats can be provided, with the two sets located at the two openings of the feed pipe. The size of the bearing seats is much smaller than the diameter of the feed pipe. The bearing seats are suspended and installed at the center of the diameter of the feed pipe through a connecting frame, so that the coagulant can pass through the bearing seats for conveying. The material extraction shaft is pivotally connected to the two bearing seats and extends through the bearing seats at one end of the treatment tank 1 into the treatment tank 1.

[0072] The spiral part 71 is mounted on the feeding shaft, and the mounting part 72 is located at one end of the treatment tank 1 and connected to the linkage 6. The spiral part 71 is mounted on the mounting part 72. The spiral part 71 can be a feeding blade. The feeding blade is mounted on the feeding shaft and located in the feed pipe between the two bearing seats.

[0073] Specifically, when the drive motor drives the rotating shaft to rotate, it drives the linkage 6 to operate. The linkage 6 is connected to the material extraction shaft, causing the material extraction shaft to rotate along the bearing seat. During the rotation of the material extraction shaft, the material extraction blades rotate. The rotation of the material extraction blades creates a negative pressure in the feed pipe and draws the coagulant in the storage tank 2 into the treatment tank 1 through the feed pipe for coagulant extraction.

[0074] The number of spiral sections 71 is at least one, that is, multiple sets of material extraction blades can be set on the material extraction shaft. The more material extraction blades there are, the faster the conveying speed of the coagulant can be accelerated. In this embodiment, three sets are used as an example.

[0075] In some embodiments, reference Figure 5 As shown, the linkage 6 includes a first linkage part 61 and a second linkage part 62; the first linkage part 61 is connected to one end of the material extraction part 7 located in the treatment pool 1. The first linkage part 61 may be a first bevel gear. The connection point between the first bevel gear and the material extraction part 7 may be one end of the material extraction shaft extending into the treatment pool 1 through the bearing seat.

[0076] The second linkage part 62 is installed on the hybrid part 5, and the first linkage part 61 is connected to the second linkage part 62. The second linkage part 62 may be a second bevel gear, and the first bevel gear and the second bevel gear mesh. The first bevel gear and the second bevel gear form a 90-degree angle. The second bevel gear is fixedly installed at the bottom end of the rotating shaft.

[0077] Specifically, when the drive motor drives the rotating shaft to rotate, the rotating shaft drives the mixing blades, the flat gear, and the second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate, thereby causing the first bevel gear to drive the extraction shaft to rotate along the bearing seat, causing the extraction blades on the extraction shaft to rotate, so as to extract the coagulant in the storage tank 2 into the treatment tank 1.

[0078] The diameter of the first linkage part 61 is smaller than that of the second linkage part 62, which makes the diameter of the second bevel gear larger and the diameter of the first bevel gear smaller. For example, when the diameter ratio of the first bevel gear to the second bevel gear is 1:2, the second bevel gear will rotate once under the drive of the drive motor, which will drive the first bevel gear to rotate twice, thereby accelerating the rotation speed of the first bevel gear and improving the material extraction speed of the material extraction part 7.

[0079] In some embodiments, reference Figure 6 As shown, a closure 9 is also provided at the connection between the treatment tank 1 and the storage tank 2. If the connection between the treatment tank 1 and the storage tank 2 is a feed hole, the closure 9 is located in the feed hole of the storage tank 2. If it is a connecting part 8, i.e. a feed pipe, the closure 9 is located in the pipe opening of the feed pipe near the storage tank 2. The closure 9 can be an electronic valve or a check valve. The valve opening direction of the check valve is the direction in which the coagulant in the storage tank 2 is conveyed to the treatment tank 1 through the feed pipe. The valve closing direction is the direction in which the water in the treatment tank 1 flows back to the storage tank 2. When the pumping blades rotate, the negative pressure in the feed pipe reaches the opening adjustment of the check valve, and the check valve opens to convey the coagulant. When the pumping blades stop rotating, the check valve loses the influence of water pressure and closes.

[0080] If the closing element 9 is an electronic valve, the electronic valve is electrically connected to the drive motor of the mixing element 5. When the drive motor is running, it sends an electrical signal to the electronic valve, and the electronic valve automatically opens. When the drive motor stops running, the electronic valve does not receive an opening electrical signal or a closing electrical signal sent by the drive motor, and the electronic valve closes.

[0081] The connection between the treatment tank 1 and the storage tank 2 can be closed when the coagulant is not being transported, and the connection can be opened when transport is required, so as to ensure the stable and accurate transport of coagulant.

[0082] A wastewater treatment process, in another embodiment, based on the above-described wastewater treatment equipment, includes the following steps:

[0083] S1. Inlet: Wastewater enters the treatment tank 1 and can be transported through an external inlet pipe.

[0084] S2. Dissolving: An additional mixing tank is set up to dissolve the solid coagulant and water in a certain proportion to form a liquid coagulant.

[0085] S3, Feeding: The dissolved liquid coagulant is conveyed to the storage tank 2 through the feeding device 4. The sensing device 3 detects that the amount of liquid coagulant is sufficient and stops feeding.

[0086] S4. Extraction: The operation of the mixing component 5 drives the extraction component 7 through the linkage component 6 to extract the liquid coagulant into the treatment tank 1.

[0087] The drive motor in the mixing unit 5 provides driving force and simultaneously achieves the mixing and pumping of sewage and coagulant.

[0088] S5, Mixing: During operation, the mixing component 5 mixes the liquid coagulant extracted by the extraction component 7 with the sewage.

[0089] The mixing and material extraction steps are performed simultaneously and are opened and closed together.

[0090] S6, Quantitative: When the sensor 3 detects that the amount of liquid coagulant in the storage tank 2 has decreased to the required conveying amount, it sends an electrical signal to the mixing unit 5 to stop pumping and mixing, and sends an electrical signal to the feeding unit 4 to replenish the liquid coagulant.

[0091] The sensor 3 can also be connected to the back-end controller, which sends and issues control commands. For example, if the sensor 3 detects that the amount in the storage tank 2 is sufficient, it sends an electrical signal to the controller. After receiving the signal, the controller sends a control command to the feeding component 4. The feeding component 4 stops feeding and, after a certain interval (the specific interval depends on the time for the precipitate of flocculants from the wastewater after coagulant mixing and the time for drainage and water replacement after collecting the flocculants), sends an start command to the mixing component 5. The mixing component 5 then performs the next round of mixing and pumping. When the controller receives the electrical signal sent by the sensor 3, it sends a stop command to the mixing component 5 and a feeding command to the feeding component 4 to stop mixing and pumping, and replenishes the storage tank 2 with coagulant through the feeding component 4.

[0092] S7. Discharge: Wastewater is mixed with liquid coagulant to produce solid flocs. After collecting the solid flocs, the treated wastewater is discharged.

[0093] The treatment tank 1 is connected to a drain pipe for discharging the mixed wastewater. Solid flocs can be collected by laying a filter screen inside the treatment tank 1, or a filter screen can be installed near the opening of the drain pipe so that the solid flocs are intercepted by the filter screen when the treated wastewater flows out. After the drainage is completed, the filter screen can be removed and recycled.
