With the increasing water pollution, drinking water health has become a general desire. Water purification devices are increasingly popular with consumers as a health product and have been widely used in daily production and life. The water purification device can purify water by using a filtering technology such as an ultrafiltration membrane, a nanofiltration membrane, a reverse osmosis membrane or ion exchange resin, so as to achieve the effect of improving the water quality.
In water purification unit's use, because current water purification unit only is equipped with a filter core, consequently, the quality of water of the water purification that obtains through purification treatment is fixed usually, can't adjust according to user's needs, leads to user experience poor. In addition, because the water quality of different cities or different areas has great difference, even the water quality of different areas of the same city often has great difference, therefore, the water quality of the effluent can not be adjusted according to the water quality conditions of different cities or different areas by the existing water purifying equipment, so that the adaptability is poor and the requirements of users on different water qualities can not be met.
Therefore, the existing water quality control method of the water purification equipment mainly depends on the types of filter materials equipped for the water purification equipment, and although the existing water purification equipment has the water quality detection function, the water purification equipment cannot adjust the water quality of the outlet water according to the detected water quality parameters, so that the intelligent control of the water quality of the outlet water cannot be realized. Therefore, it is necessary to provide a scheme capable of intelligently controlling the quality of the outlet water so as to adjust the quality of the outlet water according to the water quality conditions of different regions.
The following describes a system architecture of an embodiment of the present invention in a practical application scenario with reference to the drawings.

Specifically, the water quality detecting apparatus is an apparatus for detecting various components (e.g., BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, PH, dissolved oxygen, etc.) in water.

In some embodiments, on the basis of the water quality parameter, the on-off of the first water outlet branch and the second water outlet branch is controlled to control the water quality of the water purifying device, including: comparing the water quality parameter with a preset parameter range to determine whether the water quality parameter is within the preset parameter range, wherein the preset parameter range comprises a first parameter range and a second parameter range; when the water quality parameter is within the first parameter range, opening the first switch valve and closing the second switch valve so that the purified water filtered by the first filtering device flows to the second filtering device and flows out of the water outlet after being further filtered by the second filtering device; and when the water quality parameter is within the second parameter range, opening the second switch valve and closing the first switch valve so that the purified water filtered by the first filtering device flows to the second filtering device, flows to the third filtering device after being filtered by the second filtering device and flows out of the water outlet after being further filtered by the third filtering device.
Specifically, the preset parameter range refers to a range of the set water quality parameter. The preset parameter range may be a water quality parameter (i.e., TDS value) range preset according to empirical data, or a water quality parameter range obtained by adjusting the set water quality parameter range according to actual needs, which is not limited in the embodiment of the present invention. For example, the predetermined parameters may range from 0mg/L to 9mg/L, from 10mg/L to 60mg/L, from 40mg/L to 50mg/L, from 60mg/L to 100mg/L, from 100mg/L to 300mg/L, 300mg/L or more, and the like. Preferably, in the embodiment of the present invention, the preset parameter ranges from 0mg/L to 1000mg/L.
The preset parameter range may include a first parameter range and a second parameter range. Here, the first parameter range refers to a range of TDS values in which impurities contained in water are small, and is generally 0mg/L to 60mg/L, that is, the TDS value in the first parameter range should be greater than or equal to 0mg/L and less than or equal to 60mg/L. The second parameter range refers to the range of TDS values where the impurities contained in the water are moderate, typically 60mg/L to 300mg/L, i.e. the TDS value in the second parameter range should be greater than 60mg/L and less than or equal to 300mg/L.
After acquiring the TDS value, such as 15mg/L, the water purification apparatus determines that the TDS value is within the first parameter range, and at this time, the water purification apparatus opens the first on-off valve and closes the second on-off valve, so that the purified water filtered by the first filtering device flows to the second filtering device, and flows out of the water outlet after being further filtered by the second filtering device. After acquiring the TDS value such as 260mg/L, the water purification apparatus determines that the TDS value is within the second parameter range, and at this time, the water purification apparatus opens the second switch valve and closes the first switch valve, so that the purified water filtered by the first filtering device flows to the second filtering device, flows to the third filtering device after being filtered by the second filtering device, and flows out of the water outlet after being further filtered by the third filtering device.

Specifically, the pressure detection means is means for detecting the line pressure. The pressure detection device may include, but is not limited to, a pressure sensor, a pressure gauge, a high pressure switch, and the like. Preferably, in the embodiment of the present invention, the pressure detecting device is a high-voltage switch, which is a pressure switch that changes its operating state according to the magnitude of the pressure value in the pipeline, and has two operating states of opening and closing. Further, the pressure detection device may be disposed at any position of the main and/or branch of the pipeline, including but not limited to between the third filtering device and the water outlet, between the second switch valve and the third filtering device, between the first switch valve and the water outlet, and so on.

Preferably, in an embodiment of the present invention, the fourth switch valve is a check valve, and one end of the check valve is connected to the third filtering device, and the other end of the check valve is connected to the high-pressure switch. Furthermore, the opening direction of the one-way valve is from the third filtering device to the water outlet, so that water in the second water outlet branch can be prevented from flowing backwards, meanwhile, the one-way valve also has a certain pressure maintaining function, and when water is not taken from the water outlet, certain pressure can be stored in the second water outlet branch.
The supercharging device is a device for supercharging. Preferably, in the embodiment of the present invention, the pressure boosting device is a booster pump, and is disposed between the second filtering device and the third filtering device. The booster pump can improve the pressure of the water entering the water purifying equipment, so that the water with certain pressure passes through the third filtering device, is filtered by the third filtering device to generate drinkable direct drinking water, and flows out from the water outlet through the one-way valve and the high-voltage switch.
The preset pressure threshold refers to a set pressure threshold. The preset pressure threshold may be a pressure threshold preset according to empirical data, or may be a pressure threshold obtained by adjusting a set pressure threshold according to actual needs, which is not limited in the embodiment of the present invention. For example, the predetermined pressure threshold may be 0.02MPa, 0.1MPa, 0.25MPa, 0.3MPa, 0.32MPa, 0.5MPa, or the like.
Further, the preset pressure threshold may include a first pressure threshold and a second pressure threshold. Here, the first pressure threshold refers to a pressure threshold at which the high pressure switch is closed, and is typically 0.09Mpa, that is, when the pressure in the second water outlet branch is less than 0.09Mpa, the high pressure switch is closed; the second pressure threshold is the pressure threshold at which the high-pressure switch is open, typically 0.25Mpa, i.e. when the pressure in the second outlet branch is greater than 0.25Mpa, the high-pressure switch is open.
In some embodiments, controlling the pressure increasing device disposed between the second filtering device and the third filtering device based on the comparison result includes: when the water inlet pressure is smaller than a first pressure threshold value, starting a pressurizing device to enable the water purifying equipment to start to produce water; and when the water inlet pressure is greater than the second pressure threshold value, closing the supercharging device so as to stop the water purification equipment from producing water.
Specifically, when the water inlet pressure of the water outlet is detected to be 0.03Mpa, the water purifying equipment determines that the water inlet pressure is smaller than a first pressure threshold value, and at the moment, the water purifying equipment starts a booster pump to start water production; when the water inlet pressure of the water outlet is detected to be 0.56Mpa, the water purifying equipment determines that the water inlet pressure is larger than a second pressure threshold value, and at the moment, the water purifying equipment closes the booster pump to stop water production.
It should be noted that, when the pressure in the second water outlet branch is greater than or equal to 0.09Mpa and less than or equal to 0.25Mpa, the water purifying apparatus is in a buffering state.
In some embodiments, the water purifying apparatus further comprises a water outlet and a third water outlet branch arranged between the third filtering device and the water outlet, wherein the third water outlet branch is a bypass branch and is provided with a third on/off valve, the preset parameter range further comprises a third parameter range, and the effluent quality control method further comprises: and when the water quality parameter is in a third parameter range, opening the second switch valve and the third switch valve, closing the first switch valve, and opening the pressurizing device so that the wastewater from the third filtering device is discharged from the water outlet through the bypass branch.
Specifically, the third water outlet branch refers to a passage through which wastewater flows, and a third on-off valve is arranged in the third water outlet branch and used for controlling the wastewater flowing through the third water outlet branch. Preferably, in the embodiment of the present invention, the third water outlet branch is a bypass branch, that is, only the passage of the third on/off valve; the third switch valve is a flushing solenoid valve which is an automatic flow limiting device for adjusting water flow according to pressure intensity.
The predetermined parameter ranges may also include a third parameter range, which is a range of higher TDS values of impurities contained in the water, typically above 300mg/L, i.e. the TDS value in the third parameter range should be greater than 300mg/L.
After acquiring the TDS value, such as 620mg/L, the water purification apparatus determines that the TDS value is within the third parameter range, and then the water purification apparatus opens the second and third on/off valves and closes the first on/off valve, and opens the pressurizing means, so that the waste water from the third filtering means is discharged from the drain port through the bypass branch.
It should be noted that the discharge of the wastewater is not limited to the TDS value within the third parameter range, for example, when the water purifying device completes water production, or when the unused time of the water purifying device is greater than the preset time threshold, which is not limited by the embodiment of the present invention.
Because the treatment process of the pure water is complex, the flow is long, after the water purifying equipment operates for a long time, impurities intercepted in the water filtering process are easy to accumulate in the pipeline and the water purifying equipment, the production efficiency of the pure water is reduced, the production load of the water purifying equipment is increased, the water outlet quality is reduced, and the probability of the problems of the reverse osmosis process is the highest. Reverse osmosis, also known as Reverse Osmosis (RO), uses sufficient pressure to separate the solvent water in solution through a reverse osmosis membrane. After the water purifying equipment is used for a period of time, some trapped impurities exist on the membrane of the RO reverse osmosis filter element, and the trapped impurities can cause certain pollution to the RO reverse osmosis membrane, so that the performance of the RO reverse osmosis membrane is influenced. The back washing is the most effective method for cleaning impurities of the ultrafiltration membrane, can prevent the RO reverse osmosis membrane from being polluted, and can prolong the service life of the RO reverse osmosis membrane, so that when water is produced by water purifying equipment, or when the unused time of the water purifying equipment is greater than a preset time threshold value, the water purifying equipment can open the flushing electromagnetic valve and the booster pump so as to flush away the impurities on the RO reverse osmosis membrane.
Here, the preset time threshold may be a time threshold preset according to empirical data, or may be a time threshold obtained by adjusting a set time threshold according to actual needs, which is not limited in the embodiment of the present invention. For example, the preset time threshold may be 18 hours, one day, two days, one week, one month, etc., which is not limited in this embodiment of the present invention. Preferably, in the embodiment of the present invention, the preset time threshold is one week.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
