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 to avoid the input of high TDS raw water due to excessive accumulation of wastewater, 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 integrated wastewater storage tank. The integrated wastewater storage tank is equipped with a liquid level detection device, and the installation position of the integrated wastewater storage tank is equipped with a positioning detection device. The liquid level detection device is used to detect the water level in the integrated wastewater storage tank and is triggered when the water level in the integrated wastewater storage tank reaches a minimum liquid level threshold. The positioning detection device is used to detect the installation status of the integrated wastewater storage tank and is triggered when the integrated wastewater storage tank is reinstalled after being removed from its position. The wastewater treatment method includes: acquiring raw water quality parameters in the integrated wastewater storage tank in real time. If the raw water quality parameter is greater than or equal to the first preset water quality threshold, then based on the liquid level change trigger signal of the liquid level detection device and the box position trigger signal of the position detection device within the preset traceability time, it is determined whether to enter the multiple confirmation procedure; the multiple confirmation procedure includes: continuously detecting the raw water quality parameter multiple times at preset intervals within the preset detection time. Based on the number of abnormal occurrences of the raw water quality parameters being greater than or equal to the first preset water quality threshold during the multiple confirmation process, it is determined whether to execute the wastewater forced treatment procedure; the wastewater forced treatment procedure includes: controlling the water intake program of the water purification system to be in a prohibited state, and outputting prompt information for wastewater dumping and water replenishment; If the forced wastewater treatment procedure is executed, the determination of whether to terminate the forced wastewater treatment procedure is based on the housing arrival trigger signal of the arrival detection device and the raw water quality parameters.

[0006] When the above technical solution is adopted, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, the system determines whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the tank position trigger signal of the position detection device within the preset traceability time. Furthermore, based on the number of abnormal occurrences of the raw water quality parameters being greater than or equal to the first preset water quality threshold within the multiple confirmation process, the system determines whether to execute the wastewater forced treatment procedure. This enables the determination of wastewater accumulation and pollution levels in the integrated raw and wastewater storage tank. Through dynamic assessment and response to the degree of water quality deterioration, the wastewater forced treatment procedure is initiated. After executing the wastewater forced treatment procedure, by using the tank position status and raw water quality parameters as reset criteria, the system ensures that the wastewater dumping operation is effectively executed while maintaining the raw water quality. This avoids the continuous input of high-TDS raw water into the system, reduces the risk of reverse osmosis membrane scaling, extends filter cartridge life, and improves the safety of the effluent water quality.

[0007] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, if the raw water quality parameter is greater than or equal to a first preset water quality threshold, then determining whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the housing position trigger signal of the position detection device within a preset traceability period includes: If the raw water quality parameter is greater than or equal to the first preset water quality threshold, obtain the liquid level change trigger signal of the liquid level detection device and the box position trigger signal of the position detection device within the preset traceability time. If, within the preset traceability period, the liquid level detection device has a liquid level change trigger signal, and the position detection device does not have a box position trigger signal, then the water purification system is controlled to enter the multiple confirmation procedures.

[0008] In an optional implementation of the wastewater treatment method for the above-mentioned water purification equipment, the step of determining whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the housing position trigger signal of the position detection device within a preset traceability period if the raw water quality parameter is greater than or equal to a first preset water quality threshold further includes: If, within the preset traceability period, the liquid level detection device does not have a liquid level change trigger signal, and the position detection device does not have a tank position trigger signal, then the water purification system is controlled to execute a forced wastewater treatment procedure.

[0009] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, the step of determining whether to execute a mandatory wastewater treatment procedure based on the number of abnormal occurrences of the raw water quality parameters being greater than or equal to a first preset water quality threshold within the multiple confirmation process includes: Within a preset detection time, the raw water quality parameters are detected multiple times at preset intervals, and the number of abnormalities where the raw water quality parameters are greater than or equal to the first preset water quality threshold is determined. If the number of abnormalities is greater than or equal to the preset number, the wastewater forced treatment procedure will be executed.

[0010] 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.

[0011] 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 arrival trigger signal of the arrival detection device and the raw water quality parameters includes: If the wastewater forced treatment procedure is executed, the current raw water quality parameters are obtained when the position detection device has a housing position trigger signal; If the current raw water quality parameters are greater than or equal to the first preset water quality threshold, the wastewater forced treatment procedure will continue to be executed. If the current raw water quality parameters are less than the first preset water quality threshold, the forced wastewater treatment procedure will be terminated.

[0012] 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 latter 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.

[0013] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the housing positioning trigger signal of the positioning detection device includes both a departure action and an installation positioning action; The presence of a housing positioning trigger signal by the positioning detection device is determined as follows: The time interval between the departure action trigger signal and the installation action trigger signal of the positioning detection device is obtained; If the interval duration is greater than or equal to the preset interval duration threshold, the box positioning trigger signal is validly triggered, and it is determined that the positioning detection device has a box positioning trigger signal.

[0014] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the raw water quality parameters are less than the first preset water quality threshold and the liquid level detection device has a liquid level change trigger signal, then 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.

[0019] 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.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

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.

[0023] 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.

[0024] 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.

[0025] 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 liquid level detection device 11, and the installation position of the integrated wastewater storage tank 10 is equipped with a positioning detection device 12. 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.

[0026] 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.

[0027] 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 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.

[0028] Alternatively, the purification filter element 21 can also be an ultrafiltration (UF) filter element, a nanofiltration (NF) filter element, or a composite filter element.

[0029] 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. The water quality testing device 14 can be used to detect the TDS (Total Dissolved Solids) in the raw water; specifically, the water quality testing device is a TDS detection device.

[0030] 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 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, a higher TDS value in the raw water results in less pure water output and more wastewater output from the purification filter 21. 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 output is reduced. Therefore, by detecting raw water quality parameters, the number of water quality anomalies within a preset traceability period, and the coordinated detection of liquid level change trigger signals from the liquid level detection device and the tank positioning trigger signals from the positioning 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.

[0031] 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.

[0032] 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.

[0033] Optionally, the liquid level detection device can be installed at a height lower than that of the baffle plate 15.

[0034] 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 monitors this change in real time and, in conjunction with the flow rate data parameters from the flow detection device, treats the wastewater at different levels to improve the quality of the effluent.

[0035] Furthermore, a raw water flow detection device 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Combination Figure 2 As shown, the wastewater treatment method of the water purification equipment provided in this application includes: S21, real-time acquisition of raw water quality parameters in the integrated raw wastewater storage tank.

[0041] S22, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, then determine whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the box position trigger signal of the position detection device within the preset traceability time.

[0042] S23, based on the number of abnormal occurrences in the multiple confirmation process where the raw water quality parameters are greater than or equal to the first preset water quality threshold, determine whether to execute the mandatory wastewater treatment procedure.

[0043] S24. If the wastewater forced treatment procedure is to be executed, determine whether to terminate the wastewater forced treatment procedure based on the position trigger signal of the position detection device and the raw water quality parameters.

[0044] The multiple confirmation procedure includes: continuously testing the raw water quality parameters multiple times at preset intervals within a preset testing time; 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.

[0045] 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.

[0046] 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.

[0047] Therefore, the raw water quality parameters can reflect the pollution level of the raw water in the integrated wastewater storage tank to a certain extent. Based on this, within the preset traceability period, combined with the liquid level change trigger signal and the tank position trigger signal of the liquid level detection device, the usage status of the raw water in the integrated wastewater storage tank can be determined. Furthermore, by combining the number of abnormal times in the multiple confirmation procedures where the raw water quality parameters are greater than or equal to the first preset water quality threshold, it can be determined whether the raw water in the integrated wastewater storage tank needs to undergo mandatory wastewater dumping treatment. Furthermore, by combining the detection of the position detection device and the verification of the raw water quality, it is confirmed whether the wastewater dumping action is performed when the mandatory wastewater treatment procedure is executed, 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 integrated wastewater storage tank has a high TDS content, or avoiding the water output of the purification system.

[0048] It should be noted that the preset traceability time is as follows: starting from the moment the raw water quality parameter is detected to be greater than or equal to the first preset water quality threshold, a preset time is traced back to determine whether there is a liquid level change trigger signal from the liquid level detection device during this period. The preset detection time is as follows: starting from the moment the raw water quality parameter is detected to be greater than or equal to the first preset water quality threshold, timing begins to move forward. Thus, while maintaining the operation of the water purification system, the raw water quality parameter is continuously detected multiple times at preset intervals within the preset detection time.

[0049] Optionally, the first preset water quality threshold can be set to 300 mg / L to 500 mg / L.

[0050] 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 empty and replenish the water in the original integrated wastewater storage tank.

[0051] When the above technical solution is adopted, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, the system determines whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the tank position trigger signal of the position detection device within the preset traceability time. Furthermore, based on the number of abnormal occurrences of the raw water quality parameters being greater than or equal to the first preset water quality threshold within the multiple confirmation process, the system determines whether to execute the wastewater forced treatment procedure. This enables the determination of wastewater accumulation and pollution levels in the integrated raw and wastewater storage tank. Through dynamic assessment and response to the degree of water quality deterioration, the wastewater forced treatment procedure is initiated. After executing the wastewater forced treatment procedure, by using the tank position status and raw water quality parameters as reset criteria, the system ensures that the wastewater dumping operation is effectively executed while maintaining the raw water quality. This avoids the continuous input of high-TDS raw water into the system, reduces the risk of reverse osmosis membrane scaling, extends filter cartridge life, and improves the safety of the effluent water quality.

[0052] Combination Figure 3 As shown, in the wastewater treatment method of the water purification equipment provided in this application, if the raw water quality parameter is greater than or equal to a first preset water quality threshold, then determining whether to enter the multiple confirmation procedure based on the liquid level change trigger signal of the liquid level detection device and the housing position trigger signal of the position detection device within a preset traceability period includes: S31, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, obtain the liquid level change trigger signal of the liquid level detection device and the housing position trigger signal of the position detection device within the preset traceability time.

[0053] S32, if within the preset traceability period, the liquid level detection device has a liquid level change trigger signal, and the position detection device does not have a box position trigger signal, then the water purification system is controlled to enter the multiple confirmation procedure.

[0054] In this solution, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, it indicates that the raw water quality is poor. In this case, it is necessary to further determine whether the accumulation of pollutants is due to the original wastewater integrated storage tank not being emptied in a timely manner. Therefore, the liquid level change trigger signal of the liquid level detection device and the tank positioning trigger signal of the positioning detection device are obtained within a preset traceability period. If the liquid level detection device has a liquid level change trigger signal within the preset traceability period, it indicates that the water level in the raw water outlet space of the storage tank has fallen below the minimum preset water level during circulation, triggering the liquid 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 positioning detection device has a tank positioning trigger signal; if there is no tank positioning installation signal, it indicates that the storage tank is always in the installed position, the water in the original wastewater integrated storage tank has not been emptied, and the user may have added water. However, even though adding water dilutes the raw water in the storage tank, lowering 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 integrated wastewater storage tank does not decrease; instead, it accumulates with continuous water addition. Even if the TDS value temporarily decreases due to dilution in the short term, the impurity concentration in the remaining water will rise again as the equipment consumes water during operation. This not only leads to unstable effluent quality and bacterial growth but also causes continuous scaling or overloading of the reverse osmosis filter in the purification system. Therefore, a multiple confirmation procedure is necessary to control the continuous operation of the water purification system. This procedure confirms the raw water quality parameters during system operation, allowing for a determination of whether mandatory wastewater treatment is required.

[0055] By implementing a forced wastewater treatment procedure, water quality deterioration caused by long-term operation is prevented, avoiding the input of high-TDS raw water into the water purification system or the output of high-quality water from the system. Specifically, 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 are forced to empty their wastewater, thereby fully discharging 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.

[0056] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the raw water quality parameters are greater than or equal to the first preset water quality threshold, the determination of whether to enter the multiple confirmation procedure is based on the liquid level change trigger signal of the liquid level detection device and the box position trigger signal of the position detection device within the preset traceability time. The method further includes: if there is no liquid level change trigger signal of the liquid level detection device or no box position trigger signal of the position detection device within the preset traceability time, the water purification system is controlled to execute the wastewater forced treatment procedure.

[0057] In this solution, if the level detection device does not trigger a level change signal and the position detection device does not trigger a tank position signal within the preset traceability period, it indicates that the user may be directly adding raw water to the storage tank. However, even if adding water dilutes the raw water in the storage tank and reduces 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 is not reduced; 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 operates and water is consumed during filtration. This not only causes the effluent water quality to remain unstable, leading to 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, a forced wastewater treatment procedure needs to be implemented.

[0058] Furthermore, even if the level detection device does not have a level change trigger signal, but the position detection device has a tank position trigger signal, it is still impossible to determine whether the water in the original integrated wastewater storage tank has been poured out. In this case, it is still necessary to execute the wastewater forced treatment procedure to block the output of high TDS raw water and ensure the water quality provided by the water purification equipment.

[0059] In an optional implementation of the wastewater treatment method for the aforementioned water purification equipment, determining whether to execute a mandatory wastewater treatment procedure based on the number of abnormal occurrences of raw water quality parameters being greater than or equal to a first preset water quality threshold within the multiple confirmation process includes: Within a preset detection period, the raw water quality parameters are tested multiple times at preset intervals, and the number of abnormal raw water quality parameters that are greater than or equal to the first preset water quality threshold is determined. If the number of abnormal occurrences is greater than or equal to the preset number, a mandatory wastewater treatment procedure will be executed.

[0060] In this solution, if the number of abnormal occurrences of raw water quality parameters exceeding or equaling the first preset water quality threshold within the preset detection period is greater than or equal to a preset number, it indicates that the water quality in the integrated wastewater storage tank is continuously deteriorating, posing a risk of long-term use of high-TDS raw water, thus confirming abnormal water usage. At this point, a forced wastewater treatment procedure needs to be initiated to dump the wastewater, preventing repeated dilution from creating a false impression of water quality and masking the true pollution problem. In this way, through multi-dimensional signal cross-validation and continuous monitoring data, highly concealed improper water usage scenarios can be identified. This ensures user drinking water safety while extending the lifespan of the core filter element, ensuring that the water purification equipment consistently outputs high-quality drinking water that meets standards.

[0061] 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. 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 water intake procedure of the water purification system is prohibited, including: The purified water outlet control device is closed to cut off the purified water outlet, and / or the raw water booster device is stopped to interrupt the delivery of raw water.

[0062] 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.

[0063] 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.

[0064] Optionally, 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.

[0065] 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.

[0066] In an optional implementation of the wastewater treatment method for the aforementioned 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 arrival trigger signal of the arrival detection device and the raw water quality parameters, including: If a mandatory wastewater treatment procedure is performed, the current raw water quality parameters will be obtained when the in-place detection device detects the tank in place and triggers the signal. If the current raw water quality parameters are greater than or equal to the first preset water quality threshold, the wastewater forced treatment procedure will continue to be executed. If the current raw water quality parameters are less than the first preset water quality threshold, the mandatory wastewater treatment procedure will be terminated.

[0067] 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.

[0068] If the current raw water quality parameters are less than the first preset water quality threshold, it indicates that the water in the original wastewater integrated storage tank may have been dumped. Therefore, the forced wastewater treatment program can be terminated, and the water purification equipment can be restarted.

[0069] 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 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. 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 the forced wastewater treatment state until water quality improvement is detected and stabilizes below the first preset threshold. In this way, not only can the safety and reliability of the water purification system be improved, but the service life of the core filter element can also be effectively extended and the energy consumption of equipment operation reduced.

[0070] Combination Figure 4 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: S41, 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.

[0071] S42, 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.

[0072] The second preset water quality threshold is less than the first preset water quality threshold.

[0073] In this scheme, more precise water intake control can be achieved by classifying and determining the raw water quality parameters.

[0074] Specifically, when the water quality parameters are less 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 the forced wastewater treatment program, allowing users to take water without flow restrictions.

[0075] 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.

[0076] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, the housing position trigger signal of the position detection device includes a departure action and an installation position action; the presence of the housing position trigger signal of the position detection device is determined as follows: the interval between the departure action trigger signal and the installation position action trigger signal of the position detection device is obtained; if the interval is greater than or equal to a preset interval threshold, the housing position trigger signal is validly triggered, and the presence of the housing position trigger signal of the position detection device is determined.

[0077] In this solution, if the interval between the departure trigger signal and the installation trigger signal of the positioning detection device is greater than or equal to the preset interval threshold, the positioning trigger signal of the tank can be determined to be a valid trigger. This indicates that the user dumped the wastewater after the original integrated wastewater storage tank was moved, rather than misoperating by immediately reinstalling the original integrated wastewater storage tank after it was moved. This effectively avoids abnormalities in the wastewater treatment process caused by misjudgment.

[0078] Furthermore, after confirming that the housing positioning trigger signal is valid, the system further determines whether the current water quality parameters of the raw water meet the conditions for terminating the mandatory wastewater treatment program. If they do, the mandatory wastewater treatment program is terminated and the system switches to normal water intake mode; if not, the mandatory wastewater treatment program is maintained until the water quality meets the standards. This ensures both the safe disposal of wastewater and the safety of the effluent, effectively improving the water quality safety of the water purification system.

[0079] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the raw water quality parameters are less than the first preset water quality threshold and the liquid level detection device has a liquid level change trigger signal, then the wastewater replacement prompt procedure is executed. 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.

[0080] In this solution, if the raw water quality parameters are lower than the first preset water quality threshold and the level detection device triggers a level change signal, it indicates that the water volume in the integrated wastewater storage tank is insufficient, but the water quality has not deteriorated to the point of requiring mandatory treatment. In this case, the user can be prompted to empty the wastewater and replenish the water, thus guiding them to proactively maintain the tank. This avoids unnecessary mandatory treatment procedures, ensures timely water replenishment and efficient system operation, extends the lifespan of the purification filter, and guarantees the safety of the effluent from the purification equipment.

[0081] In an optional implementation of the wastewater treatment method of the above-mentioned water purification equipment, if the raw water quality parameters are less than the first preset water quality threshold and the liquid level detection device has a liquid level change trigger signal, before executing the wastewater replacement prompt procedure, the method further includes: if the liquid level detection device does not have a liquid level change trigger signal within a preset usage period, then 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, 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.

[0082] 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.

[0083] 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.

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.
