Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, and more specifically, to a wastewater treatment method, electronic equipment, and water purification equipment. Background Technology

[0002] Currently, with the increasing demands for drinking water quality, reverse osmosis water purifiers are widely used in homes and offices due to their high-efficiency water purification capabilities. In a reverse osmosis water purifier, the raw water is filtered through a reverse osmosis membrane and then split into two streams: one stream is pure drinking water, and the other stream is wastewater containing a higher concentration of impurities (i.e., concentrated water), thus achieving the output of purified water.

[0003] In related technologies, to achieve a compact structure and ease of use, water purifiers adopt an integrated raw and wastewater tank design. This means that raw water and wastewater share a single tank. Raw water is added to this tank before use, and wastewater generated during operation also flows back into it. During use, a low-level float switch inside the tank prompts the user to add raw water and empty the wastewater when the water level drops below or equal to a preset level. This prevents excessive wastewater accumulation from increasing the TDS (Total Dissolved Solids) of the raw water. However, this method relies solely on water level changes. If the user fails to empty the wastewater promptly and directly adds raw water, the TDS of the mixed raw water will significantly increase. This not only exacerbates the risk of scaling on the reverse osmosis membrane but also affects the quality of the effluent, posing a potential health hazard. Summary of the Invention

[0004] In view of this, this application provides a wastewater treatment method, electronic device and water purification equipment for a water purification device, so as to avoid the input of high TDS raw water when wastewater is excessively accumulated, reduce the risk of reverse osmosis membrane scaling and improve the quality of effluent.

[0005] In a first aspect, this application provides a wastewater treatment method for a water purification device. The water purification device includes an integrated wastewater storage tank and a water purification system connected to the storage tank. The storage tank is equipped with a liquid level detection device, a first positioning detection device and a weight detection device at the installation position of the storage tank, and a second positioning detection device at the installation position of the cover plate of the storage tank. The liquid level detection device is used to detect the water level in the storage tank and is triggered when the water level in the storage tank reaches a minimum liquid level threshold. The first positioning detection device is used to detect the installation status of the storage tank and is triggered when the storage tank is reinstalled after being removed from its position. The weight detection device is used to detect the weight of the storage tank. The second positioning detection device is used to detect the installation status of the cover plate of the storage tank and is triggered when the cover plate of the storage tank is reinstalled after being removed from its position.

[0006] The wastewater treatment method includes: acquiring the flow rate parameter of the water purification system in real time, wherein the flow rate parameter represents the amount of pure water produced by the water purification system or the amount of raw water in the water purification system; performing multiple response judgments based on the flow rate parameter, the liquid level change trigger signal of the liquid level detection device, the tank position trigger signal of the first position detection device, and the cover position trigger signal of the second position detection device, and executing a wastewater replacement prompt procedure or a wastewater forced treatment procedure according to the judgment result; if the wastewater forced treatment procedure is executed, determining whether to terminate the wastewater forced treatment procedure based on the tank position trigger signal of the first position detection device, the cover position trigger signal of the second position detection device, and the weight parameter of the weight detection device; wherein the weight parameter can represent the weight of the original integrated wastewater storage tank after the water level change.

[0007] By employing the aforementioned technical solution, a multi-response judgment mechanism based on multi-dimensional parameters—namely, the water flow parameters of the water purification system, the liquid level change trigger signal of the storage tank level detection device, the tank positioning trigger signal of the first positioning detection device, the cover plate trigger signal of the second positioning detection device, and the weight parameters of the storage tank weight detection device—can be constructed to determine the accumulation and pollution level of wastewater in the original integrated wastewater storage tank. Through dynamic assessment and response to the degree of water quality deterioration, differentiated wastewater replacement prompts or forced treatment procedures can be executed. Furthermore, when executing the forced treatment procedure, the tank positioning status is used as the reset condition, and the weight change of the original integrated wastewater storage tank is used as the determination condition for wastewater dumping. This ensures that wastewater dumping operations are effectively performed, preventing the continuous input of high-TDS raw water into the system, reducing the risk of reverse osmosis membrane scaling, extending filter cartridge life, and improving the safety of effluent water quality.

[0008] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, multiple response determinations are performed based on the flow rate parameter, the liquid level change trigger signal of the liquid level detection device, the tank position trigger signal of the first position detection device, and the cover position trigger signal of the second position detection device. Based on the determination results, a wastewater replacement prompt procedure or a forced wastewater treatment procedure is executed, including: If the water flow rate is less than a preset water flow threshold, determine whether the liquid level detection device has a liquid level change trigger signal; If the liquid level detection device has a liquid level change trigger signal, the wastewater replacement prompt procedure is executed. The wastewater replacement prompting program includes outputting prompts for wastewater dumping and water replenishment, and controlling the water intake program of the water purification system to be in an executable state.

If the power supply voltage parameter is within the rated operating voltage threshold of the liquid level detection device, or if the difference between the signal output level parameter and the preset reference level parameter is less than or equal to the preset deviation threshold, then the liquid level detection device is determined to be in normal working condition, and the liquid level change trigger signal of the liquid level detection device is continuously detected.

If a liquid level change trigger signal exists in the liquid level detection device within the preset traceability time, then the housing trigger signal of the first positioning detection device and the cover plate trigger signal of the second positioning detection device are acquired. If the first positioning detection device does not have a housing positioning trigger signal and the second positioning detection device has a cover positioning trigger signal, then the wastewater forced treatment procedure is executed. The wastewater forced treatment procedure includes: controlling the water intake process of the water purification system to be in a prohibited state, and outputting prompts for wastewater dumping and water replenishment.

[0011] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the water purification system includes a purified water outlet pipeline, a purification filter element installed on the purified water outlet pipeline, and a purified water outlet control device installed at the outlet end of the purified water outlet pipeline, wherein the inlet end of the purification filter element is connected to a raw water outlet pipeline, and a raw water booster device is provided on the raw water outlet pipeline. The control of the water intake procedure of the water purification system to be in a prohibited state includes: The purified water outlet control device is controlled to close to cut off the purified water outlet, and / or the raw water booster device is controlled to stop operation to interrupt the delivery of raw water.

[0012] In an optional implementation of the wastewater treatment method for the above-mentioned water purification equipment, if the forced wastewater treatment procedure is executed, determining whether to terminate the forced wastewater treatment procedure based on the housing positioning trigger signal of the first positioning detection device, the cover positioning trigger signal of the second positioning detection device, and the weight parameters of the weight detection device includes: If the wastewater forced treatment procedure is executed, the current weight parameter of the weight detection device is obtained when the first positioning detection device's housing is in position trigger signal and the second positioning detection device's cover plate is in position trigger signal. If the current weight parameter is less than the preset weight threshold, the wastewater forced treatment procedure will continue to be executed. If the current weight parameter is greater than or equal to a preset weight threshold, the forced wastewater treatment procedure will be terminated. In an optional embodiment of the wastewater treatment method of the above-mentioned water purification equipment, the current weight parameters of the weight detection device include: Obtain the current sensing signal of the current weight parameter of the weight detection device; The current sensing signal is subjected to noise reduction filtering. Within a preset time period, the stable weight data after noise reduction is determined, and the stable weight data is used as the weight parameter.

[0013] In an optional embodiment of the wastewater treatment method of the above-mentioned water purification equipment, if the current weight parameter of the weight detection device is less than a preset weight threshold, the forced wastewater treatment procedure is executed, including: Obtain the empty weight parameter and the current weight parameter of the original integrated wastewater storage tank when it is empty; the empty parameter represents the weight of the original integrated wastewater storage tank when no raw water is added; When the difference between the current weight parameter and the empty weight parameter is greater than or equal to a preset difference threshold, the wastewater forced treatment procedure is executed.

[0014] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, if the forced wastewater treatment procedure is executed, determining whether to terminate the forced wastewater treatment procedure based on the housing positioning trigger signal of the first positioning detection device and the weight parameters of the weight detection device includes: If the wastewater forced treatment procedure is executed, the current weight parameter of the weight detection device is obtained when the position detection device has a box position trigger signal; If the current weight parameter is less than the preset weight threshold, the wastewater forced treatment procedure will continue to be executed. If the current weight parameter is greater than or equal to the preset weight threshold, the forced wastewater treatment procedure will be terminated.

[0015] In an optional embodiment of the wastewater treatment method of the above-mentioned water purification equipment, the step of terminating the forced wastewater treatment procedure if the current weight parameter is greater than or equal to a preset weight threshold includes: If the current weight parameter is greater than or equal to the preset weight threshold, then obtain the current raw water quality parameter; If the current raw water quality parameters are less than the first preset water quality threshold, the forced wastewater treatment procedure will be terminated.

[0016] In an optional embodiment of the wastewater treatment method of the above-mentioned water purification equipment, the step of terminating the forced wastewater treatment procedure when the current raw water quality parameters are less than the first preset water quality threshold includes: When the current raw water quality parameters are less than the first preset water quality threshold and greater than or equal to the second preset water quality threshold, after terminating the wastewater forced treatment program, the water purification system is controlled to enter the flow-limited water intake mode. The single water intake volume of the flow-limited water intake mode does not exceed the preset flow limit value, and the time interval between two adjacent water intakes is greater than or equal to the preset interval duration. If the current raw water quality parameters are less than the second preset water quality threshold, the forced wastewater treatment procedure is terminated, and the water intake procedure of the water purification system is controlled to be in an executable state. Wherein, the second preset water quality threshold is less than the first preset water quality threshold.

[0021] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “said,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0023] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0024] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0025] As mentioned in the background section, with the increasing demands for drinking water quality, reverse osmosis water purifiers are widely used in homes and offices due to their high-efficiency water purification capabilities. In a reverse osmosis water purifier, raw water is filtered through a reverse osmosis membrane and then split into two streams: one stream produces potable pure water, and the other stream produces wastewater (concentrated water) containing a higher concentration of impurities, thus achieving purified water output. To achieve a compact structure and ease of use, the water purifiers in this technology employ an integrated raw and wastewater tank design, meaning that raw water and wastewater share a single tank. Raw water is added to this tank before use, and wastewater generated during operation is also returned to this tank. During use, a low-level float switch is installed in the tank. When the water level drops to below or equal to the preset level, the system prompts the user to add raw water and empty the wastewater to prevent excessive wastewater accumulation that could increase the TDS (Total Dissolved Solids) of the raw water. However, this method relies solely on water level changes for judgment. If users do not clean up wastewater in time and directly replenish raw water, the TDS of the mixed raw water will increase significantly. This will not only exacerbate the risk of scaling on the reverse osmosis membrane but also affect the quality of the effluent, posing a potential health hazard to drinking water.

[0026] In order to avoid excessive accumulation of wastewater and input of high TDS raw water, reduce the risk of reverse osmosis membrane scaling, and improve the quality of effluent, this application provides a wastewater treatment method, electronic equipment, and water purification equipment for a water purification device.

[0027] Combination Figure 1As shown, the water purification equipment provided in this application includes: an integrated wastewater storage tank 10 and a water purification system 20 connected to the integrated wastewater storage tank. The integrated wastewater storage tank 10 is equipped with a liquid level detection device 11, and a first positioning detection device 121 and a weight detection device 19 are provided at the installation position of the integrated wastewater storage tank 10. A second positioning detection device 122 is provided at the installation position of the cover plate of the integrated wastewater storage tank 10. The liquid level detection device 11 is used to detect the water level height inside the integrated wastewater storage tank 10, and to detect the water level when the water level in the integrated wastewater storage tank 10 reaches a certain level. The system is triggered when the minimum liquid level threshold is reached, and a liquid level change trigger signal is generated; the first position detection device 121 is used to detect the installation status of the original integrated wastewater storage tank 10, and is triggered when the original integrated wastewater storage tank 10 is reinstalled after being removed from its position; the second position detection device 122 is used to detect the installation status of the tank cover, and is triggered when the cover is reinstalled after being removed from its position; the weight detection device 19 is used to detect the weight of the original integrated wastewater storage tank 10 in real time, and can simultaneously detect the overall weight of the original integrated wastewater storage tank 10 when the liquid level in the original integrated wastewater storage tank 10 changes.

[0028] Optionally, the original integrated wastewater storage tank 10 is a detachable tank, requiring manual emptying of wastewater during use. This is suitable for environments without fixed drainage and requiring high mobility, while also reducing costs. In this solution, when the original integrated wastewater storage tank 10 is disassembled and reinstalled, the first positioning detection device 121 triggers a signal to confirm that the original integrated wastewater storage tank 10 has been reinstalled in place. When the cover is opened and then closed again, the second positioning detection device 122 triggers a signal to confirm that the cover has been operated. If the cover is operated, it indicates that the user may have opened the cover to replenish raw water. The weight detection device 19 detects the weight of the original integrated wastewater storage tank 10 to determine whether the user has emptied wastewater or injected new raw water based on the weight change.

[0029] Furthermore, the water purification system 20 includes a purification filter element 21, a purified water outlet pipe 22, and a wastewater outlet pipe 23. The purification filter element 21 is a reverse osmosis filter element. One end of the purified water outlet pipe 22 is connected to the purified water outlet end of the purification filter element 21, and the other end is equipped with a purified water outlet control device, allowing the user to connect to water. The purified water outlet pipe 22 is equipped with a flow detection device 24 to detect the pure water output of the purification filter element 21; the pure water output of the purification filter element 21 characterizes the water flow rate of the water purification system 20. The wastewater outlet pipe 23 connects the wastewater outlet end of the purification filter element 21 to the wastewater inlet end of the original integrated wastewater storage tank 10, allowing the wastewater generated by the purification filter element 21 to flow back into the original integrated wastewater storage tank 10.

[0030] Alternatively, the purification filter element 21 can also be an ultrafiltration (UF) filter element, a nanofiltration (NF) filter element, or a composite filter element.

[0031] Furthermore, a raw water output pipeline 13 is provided between the integrated wastewater storage tank 10 and the purification filter element 21, through which the raw water in the integrated wastewater storage tank 10 flows to the purification filter element 21. The raw water output pipeline 13 is equipped with a water quality testing device 14. This device can be used to detect the TDS (Total Dissolved Solids) in the raw water; specifically, it is a TDS detection device.

[0032] In this solution, the TDS detection device determines the TDS value of the raw water by detecting its conductivity. TDS is an indicator that characterizes the concentration of impurities (i.e., total dissolved solids) in water, thus representing the water quality. A high TDS value means there are many impurities in the water. Furthermore, purified water has a very low TDS value. For water purification equipment, a higher TDS value in the raw water results in less purified water output and more wastewater output from the purification filter element 21. When the TDS value of the raw water is low, the purified water output of the water purification equipment can be increased, and the wastewater output is reduced.

[0033] Optionally, the original integrated wastewater storage tank 10 is equipped with a baffle plate 15 arranged along its own height. The baffle plate 15 is set on the bottom wall of the original integrated wastewater storage tank 10, which can divide the space inside the original integrated wastewater storage tank 10 into a wastewater inlet space 101 and a raw water outlet space 102 located on both sides of the baffle plate 15. Among them, the wastewater outlet pipe 23 is connected to the wastewater inlet space 101, so that the wastewater generated by the purification filter element 21 is discharged into the wastewater inlet space; the raw water outlet pipe 13 is connected to the raw water outlet space 102, so as to transport the raw water from the raw water outlet space to the purification filter element 21 for treatment.

[0034] Optionally, the height of the baffle plate 15 is not less than one-sixth of the height of the original integrated wastewater storage tank 10. The wastewater entering the wastewater inlet space 101 gradually rises within this space and overflows from the upper edge of the baffle plate 15 into the raw water outlet space 102, gradually mixing with the raw water in the outlet space. This prevents backflowing wastewater from directly flowing into the raw water outlet pipe 13, thus preventing wastewater from short-circuiting into the purification filter element 21 and effectively improving water purification efficiency and water quality stability.

[0035] Optionally, the liquid level detection device can be installed at a height lower than that of the baffle plate 15.

[0036] Furthermore, as the wastewater in the integrated wastewater storage tank 10 continues to flow back, the TDS value in the raw water outlet space 102 gradually increases. The water quality detection device 14 can monitor this change in real time. At the same time, the flow rate data parameter of the flow detection device 24 can also reflect the gradual increase in the TDS value.

[0037] Therefore, by detecting the water flow parameters of the water purification system 20, as well as the detection of the liquid level change trigger signal of the liquid level detection device, the detection of the weight parameters of the weight detection device, the detection of the box position trigger signal of the first position detection device, and the detection of the cover position trigger signal of the second position detection device, the water quality status inside the integrated wastewater storage tank 10 can be determined, thereby enabling wastewater replacement prompts or forced treatment.

[0038] Furthermore, a raw water flow detection device 17 can be installed on the raw water output pipeline 13 to detect the raw water output of the integrated raw and wastewater storage tank 10, which is also the raw water input of the purification filter element 21. The raw water input of the purification filter element 21 can also characterize the water flow of the water purification system 20.

[0039] In addition, it should be noted that the preset threshold value of the water flow parameter is set based on the volume of the original integrated wastewater storage tank 10.

[0040] The water purification system 20 also includes a water purification outlet control device 26 installed at the outlet end of the water purification outlet pipe 22, wherein the inlet end of the purification filter element 21 is connected to the raw water outlet pipe 13, and the raw water outlet pipe is equipped with a raw water booster device 16.

[0041] Optionally, a water purification control valve may be installed on the water purification outlet pipe 22 to cut off or open the water purification outlet pipe 22.

[0042] Optionally, a raw water control valve 18 is provided on the raw water output pipeline 13 to open or close the raw water output pipeline 13.

[0043] Combination Figure 2 As shown, the wastewater treatment method of the water purification equipment provided in this application includes: S21, real-time acquisition of water flow parameters of the water purification system.

[0044] S22 performs multiple response judgments based on the water flow parameters, the liquid level change trigger signal of the liquid level detection device, the box position trigger signal of the first position detection device, and the cover plate position trigger signal of the second position detection device, and executes the wastewater replacement prompt procedure or the wastewater forced treatment procedure according to the judgment results.

[0045] S23, if the wastewater forced treatment procedure is executed, determine whether to terminate the wastewater forced treatment procedure based on the housing position trigger signal of the first position detection device, the cover plate position trigger signal of the second position detection device, and the weight parameters of the weight detection device.

[0046] Among them, the water flow rate parameter represents the amount of pure water produced by the water purification system or the amount of raw water input to the water purification system; the weight parameter represents the weight of the raw wastewater integrated storage tank after the water level changes. The wastewater replacement prompt program includes outputting prompts for wastewater disposal and water replenishment, and controlling the water intake program of the water purification system to be in an executable state; the wastewater forced treatment program includes controlling the water intake program of the water purification system to be in a prohibited state, and outputting prompts for wastewater disposal and water replenishment.

[0047] Optionally, at least two level detection devices at the same height can be installed inside the original integrated wastewater storage tank. On the one hand, this ensures that the liquid level in the tank can be cross-checked through multiple level detection devices, improving the reliability of the detection. On the other hand, if one level detection device malfunctions, the others can still operate normally, thus ensuring the stable operation and safe control of the water purification equipment. The coordinated operation of multiple level detection devices effectively avoids the invalidation of detection results due to the failure of a single detection device.

[0048] In this scheme, with the original integrated wastewater storage tank full of water and the water purification system continuously operating, since the volume of the original integrated wastewater storage tank is fixed, as the water purification system continuously purifies the raw water, the flow rate continuously increases. At the same time, the water in the original integrated wastewater storage tank gradually decreases, and wastewater continuously flows back into the original integrated wastewater storage tank. Therefore, the TDS value of the raw water flowing into the water purification system will gradually increase.

[0049] Therefore, the flow rate parameter can reflect the pollution level of the raw water in the original integrated wastewater storage tank to a certain extent. Based on this, combined with the liquid level detection device, it is possible to accurately determine whether the raw water in the original integrated wastewater storage tank needs to be replaced or subjected to forced wastewater dumping. Furthermore, combined with the detection of the first and second arrival detection devices, it is possible to verify whether the storage tank was moved away for wastewater dumping during the forced wastewater treatment procedure, and to verify whether new raw water was injected into the original integrated wastewater storage tank. Furthermore, combined with the detection of the weight detection device, it is possible to verify whether wastewater dumping was performed when the storage tank was moved away, thereby ensuring the safety and integrity of the wastewater treatment operation, and thus avoiding continuous output to the purification filter when the water in the original integrated wastewater storage tank has a high TDS content, or avoiding water output from the purification system.

[0050] Optionally, by detecting the weight parameters of the original integrated wastewater storage tank, it can be determined whether the wastewater inside the tank has been emptied after the tank is moved, thus verifying the execution of the forced wastewater treatment procedure. If the weight parameters indicate that the wastewater in the storage tank has not been effectively discharged, the forced wastewater treatment procedure needs to be continuously triggered until the original integrated wastewater storage tank is within the preset weight range.

[0051] By employing the aforementioned technical solution, a multi-response judgment mechanism based on multi-dimensional parameters can be constructed. This mechanism utilizes parameters such as the water flow rate of the purification system, the liquid level change trigger signal of the storage tank level detection device, the tank positioning trigger signal of the positioning detection device, and the weight parameters of the storage tank weight detection device. This allows for the determination of wastewater accumulation and pollution levels within the integrated wastewater storage tank. Through dynamic assessment and response to the degree of water quality deterioration, differentiated wastewater replacement prompts or mandatory treatment procedures can be executed. Furthermore, when executing mandatory treatment procedures, the tank positioning status is used as the reset condition, and the weight change of the integrated wastewater storage tank is used as the determination condition for wastewater dumping. This ensures that wastewater dumping operations are effectively performed, preventing the continuous input of high-TDS raw water into the system, reducing the risk of reverse osmosis membrane scaling, extending filter life, and improving the safety of effluent water quality.

[0052] Combination Figure 3 As shown, the wastewater treatment method of the water purification equipment provided in this application performs multiple response judgments based on raw water quality parameters, flow rate parameters, liquid level change trigger signals from the liquid level detection device, tank position trigger signals from the position detection device, and weight parameters from the weight detection device. Based on the judgment results, a wastewater replacement prompt procedure or a forced wastewater treatment procedure is executed, including: S31, if the water flow is less than the preset water flow threshold, determine whether there is a liquid level change trigger signal in the liquid level detection device.

[0053] S32, if the liquid level detection device has a liquid level change trigger signal, then execute the wastewater replacement prompt procedure.

[0054] The wastewater replacement prompt program includes outputting prompts for wastewater disposal and water replenishment, and controlling the water intake program of the water purification system to be in an executable state.

[0055] Specifically, if the flow rate is less than the preset threshold, it indicates that the purified water volume of the water purification system has not yet reached the preset threshold. In this case, even if the raw water quality parameters are high, the forced wastewater treatment procedure can be temporarily suspended to reduce the frequency of operation on the integrated wastewater storage tank. However, it is still necessary to determine whether to prompt the user to perform wastewater replacement based on the liquid level change trigger signal from the liquid level detection device. If there is no liquid level change trigger signal, the current operating status can be maintained to avoid frequent false prompts, thereby improving the user experience and the system's intelligence level. If there is a liquid level change trigger signal from the liquid level detection device, it indicates that the water volume in the integrated wastewater storage tank is low. In this case, the wastewater replacement prompt procedure can be executed directly to guide the user to empty the wastewater and replenish the raw water in a timely manner, thereby maintaining the dynamic balance of water circulation within the system.

[0056] It should be noted that while the system is displaying prompts for wastewater disposal and water replenishment, the water intake process of the water purification system is still operational. At this time, it does not affect the user's water intake or the water purification process of the system.

[0057] Optionally, the prompts for wastewater disposal and replenishment can be voice messages, light reminders, sound reminders, text prompts on the display screen, or push notifications from a mobile app, thereby reminding users to promptly address water quality issues within the original integrated wastewater storage tank.

[0058] Optionally, the preset water flow threshold for the water purification system can be 75% to 95% of the volume of the original integrated wastewater storage tank. Alternatively, it can be a value less than this range.

[0059] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, when the flow rate is less than a preset water volume threshold, determining whether there is a liquid level change trigger signal in the liquid level detection device further includes: if there is no liquid level change trigger signal in the liquid level detection device within a preset usage period, then acquiring the power supply voltage parameter and / or signal output level parameter of the liquid level detection device; if the power supply voltage parameter is within the rated operating voltage threshold of the liquid level detection device, or if the difference between the signal output level parameter and the preset reference level parameter is less than or equal to a preset deviation threshold, then determining that the liquid level detection device is in normal working condition, and continuously detecting the liquid level change trigger signal of the liquid level detection device.

[0060] Specifically, if the level detection device does not have a level change trigger signal, it could mean that the level in the original integrated wastewater storage tank has not reached the minimum level threshold, or that the level detection device itself is malfunctioning or the signal transmission is abnormal. In this case, the power supply voltage and signal output level of the level detection device can be checked to rule out false judgments caused by unstable power supply or circuit interference.

[0061] Further, the power supply voltage parameters and / or signal output level parameters of the liquid level detection device are obtained. If the power supply voltage parameters are within the rated operating voltage threshold of the liquid level detection device, or if the difference between the signal output level parameters and the preset reference level parameters is less than or equal to the preset deviation threshold, it indicates that the liquid level detection device is working normally, and the system will continue to monitor the liquid level changes in the original integrated wastewater storage tank to ensure the stable operation of the water purification equipment and water quality safety. If the power supply voltage parameters are not within the rated operating voltage threshold of the liquid level detection device, and / or if the difference between the signal output level parameters and the preset reference level parameters is greater than the preset deviation threshold, it indicates that the liquid level detection device is in a fault state. In this case, a fault prompt program can be executed to facilitate timely repair or replacement of the equipment.

[0062] Combination Figure 4As shown, in an optional implementation of the wastewater treatment method for the above-mentioned water purification equipment, multiple response determinations are performed based on the flow rate parameters, the liquid level change trigger signal of the liquid level detection device, the tank position trigger signal of the first position detection device, and the cover position trigger signal of the second position detection device. Based on the determination results, a wastewater replacement prompt procedure or a wastewater forced treatment procedure is executed. The method further includes: S41, when the water flow parameter is greater than or equal to the preset water flow threshold, obtain the liquid level change trigger signal of the liquid level detection device within the preset traceability time.

[0063] S42, if the liquid level detection device does not have a liquid level change trigger signal within the preset traceability time, and the second position detection device has a cover plate position trigger signal, then the wastewater forced treatment procedure is executed.

[0064] S43, if there is a liquid level change trigger signal in the liquid level detection device within the preset traceability time, then obtain the box position trigger signal of the first position detection device and the cover plate position trigger signal of the second position detection device.

[0065] S44, if the first positioning detection device does not have a housing positioning trigger signal and the second positioning detection device has a cover positioning trigger signal, then the wastewater forced treatment procedure is executed.

[0066] The mandatory wastewater treatment procedure includes: controlling the water intake process of the water purification system to be in a prohibited state, and outputting prompts for wastewater disposal and water replenishment.

[0067] It should be noted that the preset traceability time is: starting from the moment when the detected water flow parameter is greater than or equal to the preset water flow threshold, the preset time is traced back to determine whether there is a liquid level change trigger signal in the liquid level detection device during this period.

[0068] If the level detection device does not trigger a level change signal within the preset traceability period, it indicates that the user has added water. However, even if adding water dilutes the raw water in the integrated wastewater storage tank, reducing the TDS value, this does not remove dissolved solids such as calcium and magnesium ions and soluble salts. In other words, the total impurity content in the original integrated wastewater storage tank does not decrease; instead, it accumulates with continuous water addition. Even if the TDS value of the water may temporarily decrease due to dilution in the short term, the impurity concentration of the remaining water in the tank will rise again as the equipment consumes water during operation. This not only leads to a constantly unstable effluent quality, causing bacterial growth, but also causes continuous scaling or overload of the reverse osmosis filter in the purification system. Therefore, implementing a forced wastewater treatment procedure can effectively avoid water quality hazards caused by users adding water without authorization, ensuring that the system thoroughly replaces and treats highly polluted raw water. By controlling the water intake program of the water purification system to a prohibited state and outputting prompts for wastewater disposal and water replenishment, users can be forced to dispose of wastewater, thereby fully discharging the accumulated impurities in the original integrated wastewater storage tank, thus blocking the output of high TDS raw water and ensuring the water quality provided by the water purification equipment.

[0069] If the level detection device generates a level change trigger signal within the preset traceability period, it indicates that the water level in the raw water outlet space of the original integrated wastewater storage tank has fallen below the minimum preset water level during circulation, triggering the level detection device. At this time, the water level may rise due to wastewater backflow, and the water level may fluctuate continuously during the continuous operation of the water purification equipment. Therefore, it is necessary to further determine whether the first positioning detection device generates a tank positioning trigger signal. If no tank positioning trigger signal is generated, it means that the original integrated wastewater storage tank is always in the installed position, and the water in the original integrated wastewater storage tank has not been emptied. However, if the second positioning detection device generates a cover positioning trigger signal, it means that the user not only did not empty the raw water but also directly added raw water. This will cause the original integrated wastewater storage tank to continue accumulating, increasing the total amount of impurities and seriously threatening the purification effect. At this point, it can be determined that the water purification equipment has abnormal water addition behavior. Therefore, it is necessary to implement a forced wastewater treatment procedure to prevent water quality deterioration caused by long-term operation, avoid the input of high TDS raw water into the water purification system, or reduce the water quality output of the water purification system.

[0070] If the first positioning detection device triggers a signal indicating that the tank has been moved and reinstalled, the user may have already completed the wastewater dumping operation. Further, if the second positioning detection device triggers a signal indicating that the tank has been reinstalled and the cover is closed after being moved, the system can preliminarily determine that the user has completed the wastewater dumping and tank repositioning operations and added raw water. At this point, by obtaining the tank's weight parameter, it can be determined whether the wastewater has been dumped. Specifically, if the weight parameter is less than the preset weight threshold, it means the user has not dumped the wastewater; at this time, a large amount of high-TDS wastewater still remains in the original integrated wastewater tank, and even reinstallation has not achieved effective sewage discharge, requiring continued execution of the forced wastewater treatment program. If the weight parameter is greater than or equal to the preset weight threshold, it indicates that the original integrated wastewater tank has been emptied and refilled. At this time, it can be determined that the wastewater dumping operation has been completed, the water intake program lock of the water purification system can be released, and normal operation can be restored.

[0071] In this solution, by controlling the water intake process of the water purification system to be in a prohibited state and outputting prompts for wastewater dumping and water replenishment, the user can be forced to dump the wastewater, thereby fully discharging the accumulated impurities in the original integrated wastewater storage tank, thus blocking the output of high TDS raw water and ensuring the water quality provided by the water purification equipment.

[0072] In an optional embodiment of the wastewater treatment method of the above-mentioned water purification equipment, the water purification system includes a purified water outlet pipeline, a purification filter element installed on the purified water outlet pipeline, and a purified water outlet control device installed at the outlet end of the purified water outlet pipeline. The inlet end of the purification filter element is connected to a raw water outlet pipeline, and a raw water booster device is installed on the raw water outlet pipeline. Controlling the water intake procedure of the water purification system to be in a prohibited state includes: controlling the purified water outlet control device to close to cut off the purified water outlet, and / or controlling the raw water booster device to stop operating to interrupt the delivery of raw water.

[0073] Specifically, during normal operation of the water purification equipment, both the purified water outlet control device and the raw water booster device are in operation. The purified water outlet control device is used to control the on / off state of the purified water outlet pipeline, while the raw water booster device is used to increase the water pressure in the raw water output pipeline to ensure the normal working pressure of the purification filter element.

[0074] When the forced wastewater treatment procedure is triggered, the purified water outlet control device can be immediately shut off, and / or the raw water booster device can be stopped, thereby completely blocking purified water outlet and / or raw water input. This effectively prevents high-TDS raw water from entering the water purification system and avoids users continuing to draw water without treating the wastewater. Through the coordinated control of these two devices, it can be ensured that residual impurities in the integrated raw wastewater storage tank cannot participate in the circulation, forcibly achieving a closed-loop water purification process.

[0075] Alternatively, a water purification control valve can be installed on the water purification outlet pipe to cut off or open the water purification outlet pipe, thereby blocking or opening the water purification outlet.

[0076] Optionally, a raw water control valve is installed on the raw water output pipeline to open or close the raw water output pipeline, thereby blocking or opening the raw water output.

[0077] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if a forced wastewater treatment procedure is executed, the determination of whether to terminate the forced wastewater treatment procedure is based on the housing position trigger signal of the first position detection device, the cover plate position trigger signal of the second position detection device, and the weight parameter of the weight detection device. This includes: if the forced wastewater treatment procedure is executed, obtaining the current weight parameter of the weight detection device when both the housing position trigger signal of the first position detection device and the cover plate position trigger signal of the second position detection device are triggered; if the current weight parameter is less than a preset weight threshold, the forced wastewater treatment procedure continues to be executed; if the current weight parameter is greater than or equal to the preset weight threshold, the forced wastewater treatment procedure is terminated.

[0078] In this solution, if the forced wastewater treatment procedure is executed, even if the first positioning detection device triggers a tank positioning signal, it is still necessary to further confirm whether new raw water has been added to the original integrated wastewater storage tank. When both the first positioning detection device and the second positioning detection device trigger a cover positioning signal, it indicates that wastewater has been dumped and raw water may have been refilled. To determine whether raw water has been added, the weight parameter detected by the weight detection device can be used. If the current weight parameter is greater than or equal to a preset weight threshold, it indicates that wastewater has been dumped and new raw water has been added to the original integrated wastewater storage tank, or wastewater has not been dumped but new raw water has been added. In either case, the forced wastewater treatment procedure can be terminated to restart the effluent discharge process. If the current weight parameter is less than the preset weight threshold, it indicates that wastewater has not been dumped and / or no new raw water has been added; therefore, the forced wastewater treatment procedure must continue.

[0079] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, obtaining the current weight parameter of the weight detection device includes: obtaining the current sensing signal of the current weight parameter of the weight detection device; performing noise reduction filtering on the current sensing signal; determining the stable weight data after noise reduction within a preset time period, and using the stable weight data as the weight parameter.

[0080] In this solution, real-time sensor signals from the weight detection device are collected and noise-reducing filters are applied to effectively eliminate data fluctuations caused by environmental interference, ensuring that the obtained stable weight data accurately reflects the current state of the original integrated wastewater storage tank. Based on this, combined with a preset weight threshold, it can accurately identify whether wastewater has been dumped, thus providing a reliable basis for subsequent control logic and ensuring that the water purification system always operates in a safe and clean working state, achieving a continuous and stable output of water quality.

[0081] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the current weight parameter of the weight detection device is less than a preset weight threshold, a forced wastewater treatment procedure is executed, including: obtaining the empty weight parameter and the current weight parameter of the original integrated wastewater storage tank when it is empty; controlling the parameter to represent the weight of the original integrated wastewater storage tank when no raw water is injected; and executing the forced wastewater treatment procedure when the difference between the current weight parameter and the empty weight parameter is greater than or equal to a preset difference threshold.

[0082] In this solution, the current weight parameter is compared with the empty weight parameter to calculate the difference and determine whether the mass of residual wastewater in the original integrated wastewater storage tank exceeds the allowable range. When the difference reaches or exceeds a preset difference threshold, the system determines that the user has not disposed of the wastewater and executes a forced wastewater treatment procedure to guide the user to dispose of the wastewater and refill with raw water. This ensures that high TDS wastewater does not accumulate in the original integrated wastewater storage tank for a long time, avoiding water quality deterioration due to impurity concentration. Through continuous monitoring and judgment, combined with user operation feedback, the system can improve the automation level of the water purification equipment and effectively ensure the safety and reliability of the effluent water quality.

[0083] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the current weight parameter is greater than or equal to a preset weight threshold, the execution of the forced wastewater treatment procedure is terminated, including: if the current weight parameter is greater than or equal to the preset weight threshold, obtaining the current raw water quality parameter; if the current raw water quality parameter is less than a first preset water quality threshold, terminating the execution of the forced wastewater treatment procedure.

[0084] Furthermore, considering that the user may only move the original integrated wastewater storage tank but does not dump the wastewater, and at the same time, new raw water is injected, a comprehensive judgment needs to be made based on the raw water quality parameters in the original integrated wastewater storage tank.

[0085] If the current raw water quality parameters are lower than the first preset water quality threshold, it indicates that the water in the original integrated wastewater storage tank may have been dumped, or that the raw water quality parameters meet the requirements after injection. Therefore, the forced wastewater treatment program can be terminated, allowing the water purification equipment to resume outputting water. If the current raw water quality parameters are greater than or equal to the first preset water quality threshold, it indicates that the wastewater in the original integrated wastewater storage tank has not been effectively cleaned; or, it indicates that the water quality of the water added after the original integrated wastewater storage tank was dumped is poor; or, it indicates that the original integrated wastewater storage tank was moved but the wastewater was not dumped, and the water quality remains poor after replenishment. In this case, the forced wastewater treatment program continues to be executed, prohibiting the user from taking water, thus forcing the user to treat the water in the original integrated wastewater storage tank until the water quality returns to safe standards. In this way, through the combination of real-time monitoring and intelligent judgment, the system ensures water quality safety while avoiding health risks caused by user misoperation or neglect of maintenance. When the raw water quality parameters continuously exceed the standards, the water purification equipment will maintain a forced treatment state until the water quality is detected to have improved and stabilized below the first preset threshold. This not only improves the safety and reliability of the water purification system but also effectively extends the lifespan of the core filter element and reduces the equipment's operating energy consumption.

[0086] Combination Figure 5 As shown, in an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the current raw water quality parameters are less than a first preset water quality threshold, the forced wastewater treatment procedure is terminated, including: S51, when the current raw water quality parameters are less than the first preset water quality threshold and greater than or equal to the second preset water quality threshold, after terminating the wastewater forced treatment program, the water purification system is controlled to enter the flow-limited water intake mode. The single water intake volume in the flow-limited water intake mode does not exceed the preset flow limit value, and the time interval between two adjacent water intakes is greater than or equal to the preset interval duration.

[0087] S52, if the current raw water quality parameters are less than the second preset water quality threshold, terminate the execution of the wastewater forced treatment procedure and control the water intake procedure of the water purification system to be in an executable state.

[0088] The second preset water quality threshold is less than the first preset water quality threshold.

[0089] In this scheme, more precise water intake control can be achieved by classifying and determining the raw water quality parameters.

[0090] Specifically, when the water quality parameters are lower than the second preset water quality threshold, it indicates that the raw water quality has recovered to a relatively high level. At this time, the purification equipment can execute a forced wastewater treatment program, allowing users to take water without flow restrictions.

[0091] When the water quality parameters are between the first and second preset water quality thresholds, it indicates that although the raw water quality has entered a safe range after wastewater discharge and replenishment, there is still a certain risk of fluctuation. Activating the flow-limited water intake mode at this time can effectively reduce the load on the water purification equipment and prevent water quality deterioration caused by frequent water intake in a short period. By setting the single water intake volume to not exceed the preset flow limit and the time interval between two adjacent water intakes to not be less than the preset interval duration, both the user's basic water needs can be guaranteed, and a buffer period can be provided for water quality stability.

[0092] Secondly, this application also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor.
