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 raw wastewater storage tank and a water purification system connected to the storage tank. The water purification system has a water purification filter element. A first water quality detection device is provided on the pure water outlet pipe of the water purification filter element for detecting the pure water quality. A second water quality detection device is provided on the raw water inlet pipe of the water purification filter element for detecting the raw water quality. The raw water inlet pipe is connected to the integrated raw wastewater storage tank. An installation position detection device is provided on the integrated raw wastewater storage tank for detecting the installation status of the integrated raw wastewater storage tank, which is triggered when the integrated raw wastewater storage tank is reinstalled after being removed from its original position. The wastewater treatment method includes: during the time period between detecting the arrival trigger signal of the housing of the arrival detection device and the next arrival trigger signal of the housing, acquiring raw water quality parameters and pure water quality parameters; performing multi-path determination based on the proportional relationship between the raw water quality parameters and the pure water quality parameters; the multi-path determination includes: determining the corresponding target water quality determination path according to different water quality parameter calculation methods; determining the target determination threshold of the raw water quality parameters according to the target water quality determination path, and determining whether to execute a forced wastewater treatment procedure based on the raw water quality parameters, the pure water quality parameters, and the target determination threshold; the forced wastewater treatment procedure includes: controlling the water intake program of the water purification system to be in a prohibited state, and outputting prompts for wastewater dumping and water replenishment.

[0006] By employing the aforementioned technical solution, and through coordinated monitoring of raw water and purified water quality parameters during the usage cycle of the integrated wastewater storage tank (the period between two user relocations), and by introducing a multi-path determination mechanism based on the proportional relationship between these two parameters, a more comprehensive assessment of the water quality within the integrated wastewater storage tank can be achieved. Based on the raw water quality parameters, purified water quality parameters, and target thresholds, it can then determine whether to execute a mandatory wastewater treatment procedure. In this way, the solution can identify the degree of water quality deterioration within the integrated wastewater storage tank, avoiding the lag issues caused by relying solely on water level triggers. Through dynamic monitoring and multi-path determination of raw water and purified water quality parameters, the TDS content in the raw water can be determined, triggering the mandatory wastewater treatment procedure, cutting off the water intake function, and issuing a warning. This prevents high-TDS raw water from entering the water purification system at its source, thus avoiding 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 the effluent water quality.

[0007] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, the step of performing multi-path determination based on the proportional relationship between the raw water quality parameters and the pure water quality parameters includes: Determine the product of the raw water quality parameters and the first preset judgment coefficient; If the pure water quality parameter is less than the product of the raw water quality parameter and the first preset judgment coefficient, then it is determined to enter the raw water judgment path, wherein the target judgment threshold corresponding to the raw water judgment path is the first threshold. If the pure water quality parameter is greater than the product of the raw water quality parameter and the first preset judgment coefficient, then the water purification judgment path is entered, wherein the target judgment threshold corresponding to the water purification judgment path is the second threshold.

[0008] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, a target threshold for the raw water quality parameters is determined according to a target water quality determination path, and a mandatory wastewater treatment procedure is determined based on the raw water quality parameters, the pure water quality parameters, and the target threshold, including: If the target water quality determination path is the raw water determination path, then if the raw water quality parameters are greater than the first threshold, the wastewater forced treatment procedure will be executed. If the target water quality determination path is a purified water determination path, then if the raw water quality parameter is greater than the second threshold, the wastewater forced treatment procedure is executed; wherein, the raw water quality parameter is determined based on the ratio of the purified water quality parameter and the first preset judgment coefficient.

[0009] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the water purification system includes a pure water outlet pipeline, a water purification filter element installed on the pure water outlet pipeline, and a pure water outlet control device installed at the outlet end of the pure water outlet pipeline, wherein the inlet end of the water purification filter element is connected to a raw water input pipeline, and a raw water booster device is provided on the raw water input pipeline. The control of the water intake procedure of the water purification system to be in a prohibited state includes: The pure water outlet control device is turned off to cut off the pure water outlet, and / or the raw water booster device is stopped to interrupt the delivery of raw water.

[0010] In an optional embodiment of the wastewater treatment method for the aforementioned water purification equipment, the method further includes: After executing the wastewater forced treatment procedure, the housing position trigger signal of the positioning detection device is obtained; If a box positioning trigger signal is present, the current raw water quality parameters are obtained; If the current raw water quality parameters are greater than the target threshold, the wastewater forced treatment procedure will continue to be executed. If the current raw water quality parameters are less than the target threshold, the forced wastewater treatment procedure will be terminated.

[0011] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, a pure water tank is connected to the pure water outlet pipeline; The acquisition of raw water quality parameters and pure water quality parameters includes: Determine the water production status of the water purification system; If the water production state is characterized as a stable state, then the raw water quality parameters and the pure water quality parameters are obtained. The stable state includes: the pure water level in the pure water tank gradually increases.

[0012] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, determining the water production state of the water purification system includes: Obtain the continuous water output duration of the purification system; If, within a preset time period, the pure water quality parameter is less than the product of the raw water quality parameter and the second preset judgment coefficient, the number of abnormal pure water occurrences is accumulated; wherein, the preset time period is the preset time period before reaching the first preset time period. When the number of anomalies is greater than or equal to a preset threshold, the raw water quality parameters and the pure water quality parameters are obtained to proceed to the multi-path determination.

[0013] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the original integrated wastewater storage tank is equipped with a liquid level detection device. 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 the minimum liquid level threshold. The wastewater treatment method further includes: Obtain 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 program is executed; wherein, the wastewater replacement prompt program includes outputting prompt information for wastewater dumping and water replenishment, and controlling the water intake program of the water purification system to be in an executable state.

Detailed Implementation

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] Combination Figure 1 As 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 positioning detection device 12 at its installation location. The liquid level detection device 11 is used to detect the water level in the integrated wastewater storage tank 10 and is triggered when the water level in the integrated wastewater storage tank 10 reaches a minimum liquid level threshold. The positioning detection device 12 is used to detect the installation status of the integrated wastewater storage tank 10 and is triggered when the integrated wastewater storage tank 10 is reinstalled after being removed from its original position.

[0025] 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 positioning detection device 12 triggers a signal to confirm that the original integrated wastewater storage tank 10 has been reinstalled in place.

[0026] Furthermore, the water purification system 20 includes a water purification filter element 21, a pure water outlet pipe 22, a wastewater outlet pipe 23, and a raw water inlet pipe 24. The water purification filter element 21 is a reverse osmosis filter element. One end of the pure water outlet pipe 22 is connected to the pure water outlet of the water purification filter element 21, and the other end is equipped with a pure water outlet control device, allowing the user to connect to water. The wastewater outlet pipe 23 connects the wastewater outlet of the water purification filter element 21 to the wastewater inlet of the integrated wastewater storage tank 10, allowing the wastewater generated by the water purification filter element 21 to flow back into the integrated wastewater storage tank 10. The raw water inlet pipe 24 connects the integrated wastewater storage tank 10 to the raw water inlet of the water purification filter element 21, supplying raw water to the water purification filter element 21.

[0027] Alternatively, the water filter cartridge 21 can also be an ultrafiltration (UF) filter cartridge, a nanofiltration (NF) filter cartridge, or a composite filter cartridge.

[0028] A first water quality testing device 251 is installed on the pure water outlet pipeline 22. The first water quality testing device 251 is used to detect the TDS (total dissolved solids) in the pure water to determine the pure water quality parameters.

[0029] A second water quality testing device 252 is installed on the raw water inlet pipeline 24. The second water quality testing device 252 can be used to detect the TDS (total dissolved solids) in the raw water to determine the raw water quality parameters.

[0030] Specifically, both the first water quality testing device 251 and the second water quality testing device 252 are TDS testing devices.

[0031] In this scheme, the TDS detection device determines the TDS value of the raw water by detecting its conductivity. TDS value is an indicator that characterizes the concentration of impurities (i.e., total dissolved solids) in water, thus representing the water quality of the raw water. A high TDS value means there are many impurities in the water. Furthermore, the TDS value of purified water is very low. For water purification equipment, the higher the TDS value of the raw water, the less pure water output from the water purification filter cartridge 21 and the higher the wastewater volume. When the TDS value of the raw water is low, the pure water output of the water purification equipment can be increased, and the wastewater volume is reduced. Therefore, by coordinating the detection of raw water quality parameters and the flow parameters of the water purification system 20, and by detecting the liquid level change trigger signal of the liquid level detection device and the tank position trigger signal of the position detection device, the water quality status within the integrated raw and wastewater storage tank 10 can be determined, thereby enabling wastewater replacement prompts or forced treatment.

[0032] 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 water purification filter element 21 is discharged into the wastewater inlet space; the raw water inlet pipe 24 is connected to the raw water outlet space 102, so as to transport the raw water from the raw water outlet space to the water purification filter element 21 for treatment.

[0033] 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 in 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 inlet pipe 24, thus preventing wastewater from short-circuiting into the water purification filter element 21 and effectively improving water purification efficiency and water quality stability.

[0034] Optionally, the liquid level detection device can be installed at a height lower than that of the baffle plate 15.

[0035] 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, and the TDS value carried in the pure water also gradually increases. The first water quality detection device 251 and the second water quality detection device 252 monitor this change in real time, thereby realizing different levels of wastewater treatment to improve the pure water quality.

[0036] The water purification system 20 also includes a pure water outlet control device 26 installed at the outlet end of the pure water outlet pipeline 22. The inlet end of the water purification filter element 21 is connected to the raw water input pipeline 24, and the raw water input pipeline is equipped with a raw water booster device 16.

[0037] Optionally, a water purification control valve may be installed on the pure water outlet pipe 22 to cut off or open the pure water outlet pipe 22.

[0038] Optionally, a raw water control valve 18 is provided on the raw water input pipeline 24 to open or close the raw water input pipeline 24.

[0039] Combination Figure 2 As shown, the wastewater treatment method of the water purification equipment provided in this application includes: S21. During the period between detecting the box arrival trigger signal of the arrival detection device and the next detection of the box arrival trigger signal, acquire the raw water quality parameters and pure water quality parameters.

[0040] S22, based on the ratio of raw water quality parameters to pure water quality parameters, performs multi-path determination.

[0041] S23, determine the target judgment threshold of raw water quality parameters according to the target water quality judgment path, and determine whether to implement the mandatory wastewater treatment procedure based on the raw water quality parameters, pure water quality parameters and the target judgment threshold.

[0042] The multi-path determination includes: determining the corresponding target water quality determination path based on different water quality parameter calculation methods; the wastewater forced treatment procedure includes: controlling the water intake program of the water purification system to be in a prohibited state, and outputting prompts for wastewater dumping and water replenishment.

[0043] In this scheme, the time period between the detection of the tank's arrival trigger signal by the arrival detection device and the next detection of the tank's arrival trigger signal is the time when the original integrated wastewater storage tank is installed in place, until the time it is next lifted and removed. This period can be regarded as the service life of the original integrated wastewater storage tank.

[0044] It should be noted that, after the integrated wastewater storage tank in this application is installed and replenished with raw water, the water purification system can begin to operate and produce pure water. Ideally, during this process, part of the raw water in the integrated wastewater storage tank circulates between the storage tank and the water purification filter cartridge, the filter cartridge produces pure water, and the wastewater flows back to the storage tank as raw water.

[0045] With the original integrated wastewater storage tank full of water and the water purification system continuously operating, the volume of the original integrated wastewater storage tank is fixed. Therefore, as the water purification system continuously purifies the raw water, the flow rate increases, while the water in the original integrated wastewater storage tank gradually decreases, and wastewater continuously flows back into the original integrated wastewater storage tank. Consequently, the TDS value of the raw water flowing into the water purification system will gradually increase. Simultaneously, the TDS value of the pure water produced by the water purification filter cartridge will also gradually increase.

[0046] Therefore, based on the raw water quality parameters and pure water quality parameters within this time period, and based on the ratio of raw water quality parameters to pure water quality parameters, multi-path determination can be performed. Multi-path determination includes: determining the corresponding target water quality determination path based on different water quality parameter calculation methods; different target water quality determination paths correspond to different water quality parameters and have different target determination thresholds.

[0047] Furthermore, the decision to implement a mandatory wastewater treatment procedure can be determined based on raw water quality parameters, purified water quality parameters, and target threshold values. If the mandatory wastewater treatment procedure is implemented, the water intake process of the purification system is prohibited, and prompts for wastewater disposal and water replenishment are displayed. This effectively prevents a decline in the purification effect of the system over long-term use, ensuring that the effluent water quality consistently meets standards.

[0048] Optionally, the prompts for wastewater disposal and water replenishment can be voice messages, light reminders, sound reminders, text prompts on the display screen, or push notifications from a mobile app.

[0049] By employing the aforementioned technical solution, and through coordinated monitoring of raw water and purified water quality parameters during the usage cycle of the integrated wastewater storage tank (the period between two user relocations), and by introducing a multi-path determination mechanism based on the proportional relationship between these two parameters, a more comprehensive assessment of the water quality within the integrated wastewater storage tank can be achieved. Based on the raw water quality parameters, purified water quality parameters, and target thresholds, it can then determine whether to execute a mandatory wastewater treatment procedure. In this way, the solution can identify the degree of water quality deterioration within the integrated wastewater storage tank, avoiding the lag issues caused by relying solely on water level triggers. Through dynamic monitoring and multi-path determination of raw water and purified water quality parameters, the TDS content in the raw water can be determined, triggering the mandatory wastewater treatment procedure, cutting off the water intake function, and issuing a warning. This prevents high-TDS raw water from entering the water purification system at its source, thus avoiding 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 the effluent water quality.

[0050] In the optional implementation scheme of the wastewater treatment method of the above-mentioned water purification equipment, combined with Figure 3 As shown, based on the proportional relationship between raw water quality parameters and pure water quality parameters, multi-path determination is performed, including: S31, determine the product of the raw water quality parameters and the first preset judgment coefficient.

[0051] S32, if the pure water quality parameter is less than the product of the raw water quality parameter and the first preset judgment coefficient, then it is determined to enter the raw water judgment path, wherein the target parameter corresponding to the raw water judgment path is determined based on the raw water quality, and the target judgment threshold is the first threshold.

[0052] S33, if the pure water quality parameter is greater than the product of the raw water quality parameter and the first preset judgment coefficient, then it is determined to enter the water purification judgment path. The target parameter corresponding to the water purification judgment path is determined based on the pure water quality parameter, and the target judgment threshold is the second threshold.

[0053] Specifically, the first preset judgment coefficient can be set based on the desalination rate of the RO membrane in the water purification filter cartridge. Optionally, the first preset judgment coefficient is 10% to 20%. Preferably, the first preset judgment coefficient is 15%.

[0054] If the purified water quality parameters are less than the product of the raw water quality parameters and the first preset judgment coefficient, then the system is determined to enter the raw water judgment path. In this case, it indicates that the water purification system's processing capacity is limited, but the raw water quality is relatively normal, and the raw water quality parameters can be used as the target parameters for judgment. Furthermore, if the raw water quality parameters are greater than the first threshold, it indicates that the raw water quality has exceeded the safe range. Therefore, a forced wastewater treatment procedure can be triggered, controlling the water purification system to enter a no-water-take state to force the user to dispose of wastewater, thereby effectively blocking the input of high-TDS raw water.

[0055] If the purified water quality parameter is greater than the product of the raw water quality parameter and the first preset judgment coefficient, the system is determined to enter the water purification judgment path. This indicates that the purified water quality is better than the expected purification effect, and the raw water quality may be abnormally low or the system may be at risk of over-filtration. In this case, the purified water quality parameter can be used as the target parameter for judgment. The raw water quality parameter is then determined based on the ratio of the purified water parameter to the second preset judgment coefficient. If the raw water quality parameter determined based on the effluent water quality parameter is greater than the second threshold, it indicates that the raw water quality has seriously exceeded the standard. Therefore, a forced wastewater treatment procedure can be triggered, controlling the water purification system to enter a no-water-take state to force the user to dispose of wastewater, thereby effectively blocking the input of high TDS raw water and protecting the water purification filter cartridge.

[0056] Both of the aforementioned decision paths ultimately determine whether to trigger a mandatory wastewater treatment procedure by comparing the raw water quality parameters with corresponding thresholds. Whether it's the direct comparison in the raw water decision path or the comparison after inferring raw water parameters from pure water parameters in the purified water decision path, the core objective is to accurately identify the risk of high TDS raw water input. When the system determines there is a risk of exceeding the standard, it immediately prohibits water intake and prompts the user to treat the wastewater until the water quality returns to normal. This proactively protects the water purification system, ensuring stable and safe effluent quality and improving equipment reliability and user experience. Through dynamic path selection and dual-threshold control, adaptability and safety under different water quality conditions are balanced.

[0057] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, a target judgment threshold for the raw water quality parameters is determined according to the target water quality judgment path, and a mandatory wastewater treatment procedure is determined based on the raw water quality parameters, the pure water quality parameters, and the target judgment threshold. This includes: if the target water quality judgment path is the raw water judgment path, then a mandatory wastewater treatment procedure is executed if the raw water quality parameters are greater than a first threshold; if the target water quality judgment path is the purified water judgment path, then a mandatory wastewater treatment procedure is executed if the raw water quality parameters are greater than a second threshold; wherein the raw water quality parameters are determined based on the ratio of the pure water quality parameters to a first preset judgment coefficient.

[0058] Through the above scheme, when the target water quality determination path is the raw water determination path, if the raw water quality parameters exceed the first threshold, it indicates that the raw water quality has exceeded the safe range. Therefore, a forced wastewater treatment program can be triggered, controlling the water purification system to enter a water intake prohibition state, forcing the user to dispose of wastewater, thereby effectively blocking the input of high TDS raw water. If the target water quality determination path is the purified water determination path, and the raw water quality parameters derived from the pure water quality parameters exceed the second threshold, it is also determined to be a high TDS input risk, triggering a forced wastewater treatment program, prohibiting water intake, and prompting the user to treat the wastewater until the water quality returns to the normal range. This dual-path collaborative mechanism ensures accurate risk identification under different water quality conditions, improving system safety and adaptability. By dynamically selecting the raw water or purified water determination path, the system can flexibly cope with complex water quality environments, extending filter life while ensuring effluent quality. In this way, not only is the identification accuracy of high TDS water by the water purification equipment enhanced, but the user's water safety and management intelligence level are also improved.

[0059] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, a pure water outlet control device is provided at the outlet end of the pure water outlet pipeline, and a raw water booster device is provided on the raw water inlet pipeline; controlling the water intake procedure of the water purification system to be in a prohibited state includes: controlling the pure water outlet control device to close to cut off the pure water outlet, and / or controlling the raw water booster device to stop operating to interrupt the delivery of raw water.

[0060] 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 pure water outlet pipeline, while the raw water booster device is used to increase the water pressure in the raw water inlet pipeline to ensure the normal working pressure of the purification filter element.

[0061] 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 storage tank cannot participate in the circulation, forcibly achieving a closed-loop water purification process.

[0062] Alternatively, a water purification control valve can be installed on the pure water outlet pipeline to cut off or open the pure water outlet pipeline, thereby blocking or opening the pure water outlet.

[0063] Optionally, a raw water control valve is installed on the raw water inlet pipeline to open or close the pipeline, thereby blocking or opening the raw water output. By controlling the on / off states of the purified water control valve and the raw water control valve, independent or coordinated control of the purified water output and raw water input can be achieved. When the system detects a high TDS risk, it automatically closes the purified water control valve and cuts off the raw water control valve to prevent contamination from spreading. Valve actions and alarm signals can be triggered synchronously to ensure users are promptly informed and can handle any abnormalities.

[0064] In an optional embodiment of the wastewater treatment method for the aforementioned water purification equipment, the method further includes: After the wastewater forced treatment procedure is executed, the housing of the positioning detection device is triggered to be in position. If a box positioning trigger signal is present, the current raw water quality parameters are obtained; If the current raw water quality parameters are greater than the target threshold, the mandatory wastewater treatment procedure will continue to be executed; if the current raw water quality parameters are less than the target threshold, the mandatory wastewater treatment procedure will be terminated.

[0065] In this solution, after the forced wastewater treatment procedure is executed, the system uses the positioning trigger signal from the positioning detection device to confirm whether the user has moved the original integrated wastewater storage tank to empty the wastewater. Specifically, if a positioning trigger signal is present, it indicates that the original integrated wastewater storage tank has been moved and reinstalled. At this time, the user may have replenished the raw water. By acquiring the current raw water quality parameters and comparing them with the target judgment threshold determined in the aforementioned solution, it can be determined whether the replenished raw water meets the water quality requirements for the operation of the water purification system. If the current raw water quality parameters are still greater than the target judgment threshold, the forced wastewater treatment procedure continues to be executed to prevent unqualified water from entering the purification process; if they are less than or equal to the target judgment threshold, it indicates that the water in the original integrated wastewater storage tank may have been emptied. Therefore, the forced wastewater treatment procedure can be terminated, allowing the water purification equipment to restart. If the current raw water quality parameters are greater than or equal to the target 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 emptied is poor; or, it indicates that the original integrated wastewater storage tank was moved but the wastewater was not emptied, and the water quality remains poor after replenishment. In this case, the forced wastewater treatment program will continue to be executed, prohibiting users from taking water, thus forcing users 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 continue to exceed the standard, the water purification equipment will maintain a forced treatment state until the water quality is detected to have improved and stabilized below the target threshold. This achieves a dynamic balance between water quality safety and equipment operating efficiency, avoids the risk of system restart due to human operation delays or misjudgments, improves the safety and reliability of the water purification system, extends the service life of the core filter element, and reduces equipment operating energy consumption.

[0066] Furthermore, if there is no trigger signal indicating the tank is in place, it means the user has not moved the original integrated wastewater storage tank nor dumped the wastewater. However, there is a possibility that the user directly adds raw water. Even if raw water is added, this does not remove dissolved solids such as calcium and magnesium ions and soluble salts from the water. In other words, the total impurity content in the original integrated wastewater storage tank has not decreased; instead, it will continue to accumulate 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 water is consumed during equipment operation. This not only leads to a constantly unstable effluent quality and causes bacterial growth in the water, but also causes the reverse osmosis filter element of the purification system to continuously scale or operate under overload. Therefore, in this case, a forced wastewater treatment procedure must be executed to avoid water quality hazards caused by the user adding water privately and to ensure that the system thoroughly replaces and treats the 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 storage tank, thus blocking the output of high TDS raw water and ensuring the water quality provided by the water purification equipment.

[0067] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, a pure water tank is connected to the pure water outlet pipe; obtaining raw water quality parameters and pure water quality parameters includes: determining the water production state of the water purification system; if the water production state is characterized as a stable state, then obtaining the raw water quality parameters and pure water quality parameters; the stable state includes: the pure water level in the pure water tank gradually increases.

[0068] In this solution, by determining and acquiring raw water quality parameters and purified water quality parameters when the water production process is stable, measurement interference during system start-up, shutdown, or fluctuations can be effectively eliminated, improving the accuracy and representativeness of data acquisition. The water quality parameters acquired at this time more accurately reflect the actual treatment effect during the water purification process, providing a reliable basis for subsequent water quality assessment and control strategies. Combined with the trend of a continuously rising purified water level, it can be further confirmed that the system is in a continuous water production stage, avoiding misjudgments due to transient fluctuations. Based on this, by combining the proportional relationship between raw water quality parameters and purified water quality parameters, the purification efficiency and fouling degree of the reverse osmosis membrane can be determined, thereby identifying whether the water purification effect of the filter cartridge has declined, and thus triggering timely warnings or maintenance prompts.

[0069] In the optional implementation scheme of the wastewater treatment method of the above-mentioned water purification equipment, combined with Figure 4 As shown, determining the water production status of the water purification system includes: S41, obtain the continuous water output duration of the purification system.

[0070] S42, within the continuous water output time, if the pure water quality parameter is less than the product of the raw water quality parameter and the second preset judgment coefficient within a preset time period, the number of abnormal pure water outputs is accumulated; wherein, the preset time period is the preset time period before the first preset time period is reached.

[0071] S43, when the number of anomalies is greater than or equal to the preset anomaly threshold, the raw water quality parameters and pure water quality parameters are obtained to enter the multi-path determination.

[0072] Specifically, when the water production state of the purification system is stable, the above scheme can determine whether there are any abnormalities in the pure water preparation process. That is, if, within a preset time period, the pure water quality parameters are less than the product of the raw water quality parameters and a second preset judgment coefficient, it indicates that the pure water quality has not achieved the expected purification effect, possibly due to a decline in reverse osmosis membrane performance or excessive raw water load. By accumulating the number of abnormalities and combining it with a preset threshold, potential risks in the continuous water production process can be effectively identified, avoiding misjudgments caused by occasional fluctuations. When the number of abnormalities reaches the threshold, the collection of raw water quality parameters and pure water quality parameters is triggered. The raw water and pure water quality parameters obtained at this time are based on the stable operation phase of the system, have higher representativeness and reliability, and can accurately reflect the actual treatment performance of the water purification system under continuous operating conditions. By further combining the changing trends of raw water quality parameters and pure water quality parameters, it is possible to monitor the changes in TDS (soluble solids, ion concentration, and organic matter content) in the raw water. This allows for the execution of a forced wastewater treatment procedure, compelling users to dump their wastewater and preventing secondary pollution or a decrease in the efficiency of the water purification system due to wastewater accumulation. This ensures the subsequent water purification effect and protects the water purification filter cartridge.

[0073] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the original integrated wastewater storage tank is equipped with a liquid level detection device. 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 the minimum liquid level threshold. Wastewater treatment methods also include: To determine if the liquid level detection device has a liquid level change trigger signal; If the liquid level detection device generates a liquid level change trigger signal, the wastewater replacement prompt program is executed. The wastewater replacement prompt 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.

[0074] 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.

[0075] In this solution, if there is no liquid level change trigger signal, the current operating state 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 means that the water volume in the storage tank is low. At this time, the wastewater replacement prompt program can be executed directly to guide the user to empty the wastewater and replenish the original water in a timely manner, thereby maintaining the dynamic balance of water circulation in the system.

[0076] 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.

[0077] 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.

[0078] In this solution, if the forced wastewater treatment procedure is executed, even if the positioning detection device detects a tank positioning trigger signal, it is still necessary to confirm whether the wastewater in the original integrated wastewater storage tank has been dumped. Considering that the user may only move the original integrated wastewater storage tank but does not dump the wastewater, a comprehensive judgment must be made based on the raw water quality parameters.

[0079] 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. When the processor executes the computer program, it implements the wastewater treatment method of the water purification device as described in any of the above embodiments.
