[0063] Furthermore, the concentrated water collection tank 1 is connected to the flushing valve 7 to obtain the concentrated water generated during the water production process through the flushing valve 7.

[0064] Furthermore, the first preset height, the second preset height, and the third preset height are adjustable.

[0065] Please refer to Figure 2 , Figure 2 which is an organizational schematic diagram of a water supply system provided by an embodiment of the present application. The water supply system can be a large-scale centralized water purification and supply system, which is a reverse osmosis water purification system that can supply an entire floor. As Figure 2 shown, in addition to the concentrated water utilization subsystem, the water supply system may further include a raw water makeup valve 8, a raw water tank 9, a liquid level float 10, a raw water pump 11, a pressure gauge 12, a multi-media filter 13, a pressure gauge 14, an activated carbon filter 15, a scale inhibitor dosing device 16, a liquid level float 17, a fine filter 18, an inlet solenoid valve 19, a low-pressure protection 20, a pressure gauge 21, a high-pressure pump 22, a standby high-pressure pump 23, a pressure gauge 24, a pressure gauge 25, reverse osmosis membrane elements 26-29, FI-1, a product water conductivity detector 30, a RO pure water tank 31, a water purification and supply variable-frequency pump 32, an ultraviolet sterilizer 33, a fine filter 34, a pressure gauge 35, a flushing valve 36, a product water valve 37, a chemical cleaning bucket 38, a chemical cleaning pump 39, a chemical cleaning valve 40 and other components.

[0066] Among them, the raw water makeup valve 8 is used to supplement raw water into the raw water tank 9 until the water level reaches the preset water level height when it is opened; the liquid level float valve 10 is of two-stage type and can detect high and low water levels; the raw water pump 11 has self-priming and boosting functions, and the first-stage multi-media filter 13 can be made of filter materials such as quartz sand, manganese sand, and resin. Both the multi-media filter 13 and the activated carbon filter 15 are equipped with backwashing valve heads and can backwash the filter elements.

[0067] Figure 2 The water production and supply process of the water supply system shown can include:

[0068] 1. Raw water tank water replenishment process: There is a liquid level float 10 in the raw water tank 9. This liquid level float 10 has three water levels: high, medium, and low. When it is detected that the water level of the liquid level float 10 is at the low water level, the raw water replenishment valve 8 will be opened, and municipal tap water will directly replenish the raw water tank 9 through the raw water inlet until the water level reaches the high water level position. The outlet of the raw water tank 9 connected to the raw water pump 11 is much lower than the low water level position of the liquid level float 10.

[0069] 2. Raw water pump startup process: When it is detected that the liquid level in the raw water tank 9 is greater than or equal to the medium water level, the raw water pump 11 is started. At this time, the raw water pump 11 will send the raw water to the multi-media filter 13 and the activated carbon filter 15 until it is detected by the pressure gauges 12 and 14 that the water pressure is greater than 0.1 Mpa, indicating that the two-stage filter elements are already filled with raw water. At this time, the water will continue to flow into the fine filter 18. The pressure gauges 12 and 14 provide pressure values to the raw water pump 11. When the pressure is greater than the preset pressure, the pump stops; when the pressure is less than the preset pressure, the pump starts.

[0070] 3. Water production process: When the inlet solenoid valve 19 is opened and the low-pressure switch ( Figure 2 the low-pressure protection 20 + pressure gauge 21 in it) detects that the inlet water pressure is greater than 0.1 Mpa, the high-pressure pump 22 is started, and the gate valves at the inlet and outlet of the standby high-pressure pump 23 are in the closed state. The flush valve 7 is closed. At this time, the filtered purified water will flow into the RO water tank 31, and the RO water tank 31 has a liquid level float and a vent hole. At the same time, the liquid level float can detect three liquid level heights: high, medium, and low.

[0071] 4. Water supply process: When the system detects that the water level in the RO water tank 31 is at the low water level, the above water production process needs to be started at this time. When the system detects that the water level in the RO water tank 31 is greater than or equal to the medium water level, the purified water supply variable frequency pump 32 is turned on, the ultraviolet sterilizer 33 is turned on, and the water is further deeply filtered through the fine filter 34 and then supplied to users through the water production valve pipeline. The manual ball valve in the pipeline is in the normally open state. The pressure gauge 35 mainly provides pressure values to the purified water supply variable frequency pump 32. When the pressure reaches the preset value, the pump stops; when it is less than the preset value, the pump starts.

[0072] 5. Purified water reflux process: When the purified water supply variable frequency pump 32 has not been used for the preset time, the purified water reflux process is started. The preset time here can be set according to user needs, and the system initial default value can be 4 hours. As long as no one uses the purified water, the system will first detect whether the liquid level float in the RO water tank 31 is greater than the medium water level. If it is greater than the medium water level, the purified water supply variable frequency pump 32 is turned on, the ultraviolet sterilizer 33 is turned on, and the flush valve 36 is turned on to perform secondary fine filter filtration on the stored water in the system pipeline and perform secondary sterilization at the same time to prevent bacteria from growing. If the system detects that the water level in the RO water tank 31 is less than the low water level, then the system will enter the water production process.

[0073] 6. Concentrated water collection and supply process: The wastewater generated during water production and flushing in the system is stored in the concentrated water collection tank 1. There is a liquid level float 5 in this tank, and the liquid level float 5 has three water levels, corresponding to high, medium, and low water levels respectively. At the same time, the concentrated water collection tank 1 is also connected to an overflow port and the water inlet of municipal tap water. The function of the overflow port is that when the amount of wastewater used by the user is less than the wastewater discharge volume, the excess wastewater can be discharged into the sewer. If the amount of wastewater used by the user is much larger than the collected wastewater volume, then at this time, it can be supplemented with municipal tap water to meet the user's usage requirements. The pressure gauge 6 mainly provides pressure values to the wastewater supply variable-frequency pump 3. When the pressure is higher than the preset pressure, it indicates that no one is using water, and this pump stops working. If the pressure is less than the preset value, it indicates that the pipeline pressure is insufficient, and this pump needs to be started. When the liquid level float 5 detects that the water level in the concentrated water collection tank 1 is greater than the low water level, at this time, the wastewater discharge valve 2 and the wastewater supply variable-frequency pump 3 can be opened to supply water to the user. These waters are mainly connected to the toilet pipeline and the mopping faucet pipeline in the user's home. When the system detects that the entire system is producing water normally, and at the same time the wastewater supply variable-frequency pump 3 is also turned on, but the liquid level float 5 in the concentrated water collection tank 1 stays at the low water level for more than the preset time, at this time, the inlet solenoid valve 4 needs to be opened for water replenishment. When the water level in the concentrated water collection tank 1 reaches the medium water level, the water replenishment of the inlet solenoid valve 4 stops. When the system detects a signal from the high water level of the liquid level float 5 and the system is still producing water, then these wastewaters are directly discharged through the overflow port.

[0074] 7. Scale inhibitor addition process: When FI-1 on the concentrated water pipeline detects that the hardness of the system reaches the preset value, for example, when it reaches 260 mg / L, then the system needs to start the scale inhibitor dosing device 16. At this time, the scale inhibitor dosing device 16 needs to first detect whether the liquid scale inhibitor is greater than the low liquid level. If it is greater than the low liquid level, then at this time, the medicine delivery pump is turned on, and the liquid scale inhibitor is sent into the pipeline according to the preset total amount. If the liquid level float 17 detects that the liquid level is less than the low liquid level, then at this time, liquid scale inhibitor needs to be added until a signal is detected at the high liquid level.

[0075] 8. Medicine washing process: The system first detects whether the washing liquid in the medicine washing bucket 38 is greater than the medium water level. If it is greater than the medium water level, then at this time, the medicine washing pump 39 and the medicine washing valve 40 are opened. The medicine washing pump can work in a cycle all the time. After the cycle time reaches the preset design time, this process stops. If the liquid level float in the medicine washing bucket 38 detects that the liquid level of the washing liquid is lower than the low water level, then medicine liquid needs to be added until it is greater than the medium water level before the medicine washing pump 39 and the medicine washing valve 40 can be started. When the liquid level float in the medicine washing bucket 38 detects the high liquid level, the addition of medicine liquid stops.

[0076] Please refer to Figure 2 , Figure 2The figure is a flowchart of a method for using concentrated water provided by an embodiment of the present application. The present application provides the method operation steps as described in the embodiment or flowchart, but based on routine or non-creative labor, it may include more or fewer operation steps. The step order listed in the embodiment is only one way among the execution orders of numerous steps and does not represent the only execution order. When the actual system or server product is executed, it can be executed in the method order shown in the embodiment or the accompanying drawings or executed in parallel (for example, in an environment of parallel processors or multi-threaded processing). As Figure 2 shown, a method for using concentrated water provided by an embodiment of the present application can be applied to a Figure 1 concentrated water utilization subsystem as shown. Specifically, it may include the following steps:

[0077] S210: During the water production process, determine the current liquid level height of the liquid level float in the concentrated water collection tank, and the concentrated water collection tank is used to store the generated concentrated water.

[0078] Feasibly, the current liquid level height detected by the liquid level float can indicate that the concentrated water in the concentrated water collection tank is at a low water level, a medium water level, or a high water level. The low, medium, and high water levels can be preset artificially in advance.

[0079] S220: If the current liquid level height is higher than the first preset height, open the wastewater discharge valve and the wastewater supply variable frequency pump.

[0080] Among them, the first preset height is the preset low water level height. The current liquid level height being higher than the first preset height can also be regarded as the current amount of concentrated water being able to meet a certain degree of domestic water demand.

[0081] Among them, the wastewater discharge valve and the wastewater supply variable frequency pump are used to transfer the stored concentrated water to the domestic water outlet to use the concentrated water as domestic water, such as for toilet flushing and mop flushing, improving the utilization rate of concentrated water and reducing environmental pollution.

[0082] S230: During the process of transferring the concentrated water in the concentrated water collection tank to the domestic water outlet through the first outlet of the concentrated water collection tank, the wastewater discharge valve, and the wastewater supply variable frequency pump, if the current liquid level height is lower than the first preset height, open the inlet solenoid valve to supplement tap water into the concentrated water collection tank.

[0083] It can be understood that the current liquid level height being lower than the first preset height means that the generation rate of concentrated water is lower than the usage amount of domestic water, and the currently remaining amount of concentrated water may not be able to meet the domestic water demand, and the situation of running out of concentrated water may occur during the process of using concentrated water as a type of domestic water, reducing the user experience.

[0084] Therefore, in the embodiments of the present application, during the process of concentrated water transmission and use, if the current liquid level height is lower than the first preset height, tap water is replenished into the concentrated water collection tank, which can ensure that users can use domestic water smoothly.

[0085] Wherein, the water inlet of the water inlet solenoid valve is connected to the municipal tap water port, and the water outlet of the water inlet solenoid valve is connected to one water inlet of the concentrated water collection tank, and the connection position needs to be higher than the position of the first preset height.

[0086] In an embodiment of the present application, after the water inlet solenoid valve is opened when the current liquid level height is lower than the first preset height, the method further includes:

[0087] If the current liquid level height reaches the second preset height, the water inlet solenoid valve is closed.

[0088] Wherein, the second preset height is higher than the first preset height. The second preset height can be the preset middle water level height. That is to say, the replenishment with tap water is also limited, so as to make the best use of concentrated water as domestic water and improve the utilization rate of concentrated water.

[0089] In an embodiment of the present application, the method further includes:

[0090] If the current liquid level height is higher than the third preset height, the concentrated water in the concentrated water collection tank is discharged through the second outlet of the concentrated water collection tank until the current liquid level height is lower than the third preset height.

[0091] Wherein, the third preset height is higher than the first preset height and higher than the second preset height. The third preset height can be the preset high water level height. When the current liquid level height is higher than the third preset height, it indicates that the concentrated water collection tank is about to be full, and the generation speed of concentrated water is greater than the usage amount as domestic water. In order not to overflow, a part of the concentrated water needs to be discharged.

[0092] In an embodiment of the present application, determining the current liquid level height where the liquid level float in the concentrated water collection tank is located includes:

[0093] Determining the pressure data at the domestic water outlet;

[0094] In the case where the pressure data is lower than the first preset threshold, determining the current liquid level height where the liquid level float in the concentrated water collection tank is located;

[0095] In the case where the pressure data is higher than the second preset threshold, keeping the waste water discharge valve and the waste water supply variable frequency pump in the closed state.

[0096] Wherein, the first preset threshold is lower than the second preset threshold, and the first preset threshold and the second preset threshold can be specifically determined according to the water pressure range during actual water use.

[0097] When the pressure data is higher than the second preset threshold, it indicates that no one is using water, and the wastewater discharge valve and the wastewater supply frequency converter can be stopped and remain closed; when the pressure data is lower than the second preset threshold, it indicates that the pipeline pressure is insufficient. At this time, someone is using water, and the wastewater discharge valve and the wastewater supply frequency converter need to be opened to execute the concentrated water utilization method provided by the embodiments of the present application.

[0098] In an embodiment of the present application, during the process of concentrated water utilization, if it is detected that the pressure data is higher than the second preset threshold, the operation of the concentrated water utilization subsystem can be stopped, including stopping the operation of the wastewater discharge valve, the wastewater supply frequency converter or the inlet solenoid valve.

[0099] In an embodiment of the present application, the method further includes:

[0100] Determine the amount of concentrated water utilized transmitted by the wastewater discharge valve and the wastewater supply frequency converter pump within a preset statistical period, as well as the amount of concentrated water discharged transmitted from the second outlet of the concentrated water collection tank;

[0101] Adjust the first preset height and the third preset height according to the amount of concentrated water utilized and the amount of concentrated water discharged.

[0102] Among them, the preset statistical period can be in units of days or weeks, and there is no limitation here.

[0103] Specifically, when the proportion of the amount of concentrated water utilized in the total amount is relatively low or the proportion of the amount of concentrated water discharged in the total amount is relatively high, it indicates that a relatively large proportion of the generated concentrated water has not been utilized, and there is still room for improvement in the utilization rate of concentrated water. The third preset height can be increased or the first preset height can be decreased, so as to further improve the utilization rate of concentrated water.
