[0002] The hospital disinfection supply center is an important unit for disinfecting medical equipment and materials. To ensure the disinfection effect of medical equipment and the integrity of equipment materials, it is crucial to ensure that clean pure water, especially the water used for terminal rinsing, meets the standards (for example, the conductivity of the water used for terminal rinsing needs to be less than 15us / cm).

[0003] In practical applications, raw water is usually treated using conventional membrane purification technology.

The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0020] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0021] In one embodiment of the present application, a disinfection water treatment system includes: a raw water tank, a filtration and reverse osmosis module, a pure water tank, an ultraviolet sterilization device, a conductivity monitoring device and a three-way valve; the water outlet of the raw water tank is connected to the water inlet of the pure water tank through the filtration and reverse osmosis module, the water outlet of the pure water tank is connected to the water inlet of the three-way valve through the ultraviolet sterilization device, the first water outlet of the three-way valve is connected to the water inlet of the raw water tank, and the second water outlet of the three-way valve is connected to the water inlet of the pure water tank; the conductivity monitoring device is arranged on the connecting pipeline between the water outlet of the ultraviolet sterilization device and the water inlet of the three-way valve, and is used to monitor the conductivity of water in the connecting pipeline; the three-way valve is used to control the first water outlet to be closed and the second water outlet to be opened when the conductivity monitoring result is qualified; or, to control the first water outlet to be opened and the second water outlet to be closed when the conductivity monitoring result is unqualified.

[0022] In this embodiment, by setting up a filtration and reverse osmosis module and an ultraviolet sterilization device, the raw water is filtered and reverse osmosis is performed to remove impurities such as suspended matter, particulate matter, colloids, and bacteria. The raw water after the impurities are removed is sterilized by the ultraviolet sterilization device and then enters the connecting pipe. The conductivity of the water in the connecting pipe is monitored. If the conductivity monitoring result is unqualified, the water in the connecting pipe enters the raw water tank through the second water outlet of the three-way valve, and is filtered, reverse osmotic and sterilized again until the conductivity monitoring result of the water in the connecting pipe is qualified after the second treatment, thereby ensuring that the water treated by the disinfection water treatment system meets the standards for terminal rinsing water, thereby avoiding secondary contamination when cleaning and disinfecting medical equipment and materials.

[0023] In this embodiment, the conductivity monitoring device is used to online monitor the conductivity of the water in the connecting pipe. If the conductivity of the water in the connecting pipe is greater than a preset conductivity threshold, the conductivity monitoring result is judged to be unqualified; if the conductivity of the water in the connecting pipe is less than or equal to the preset conductivity threshold, the conductivity monitoring result is judged to be qualified.

[0024] In this embodiment, raw water refers to water taken from natural water bodies or water storage bodies (such as rivers, lakes, ponds or underground aquifers, etc.). These waters have not undergone any artificial purification treatment before being used as water supply sources. The water quality of these water sources varies depending on various factors such as geographical location, climatic conditions, and geological structure.

[0025] In one embodiment of the present application, the filtration and reverse osmosis module includes: a filtration module and a reverse osmosis module; the water outlet of the raw water tank is connected to the water inlet of the filtration module, the water outlet of the filtration module is connected to the water inlet of the reverse osmosis module, and the water outlet of the reverse osmosis module is connected to the water inlet of the pure water tank.

[0026] In this embodiment, the filtration module removes impurities such as suspended matter, colloids, and bacteria from the raw water. The reverse osmosis module is a first-stage reverse osmosis device that removes impurities such as suspended matter, colloids, bacteria, ions, organic matter, and heavy metals from the raw water. The filtration of the raw water by the filtration module and the reverse osmosis module improves its purity. The reverse osmosis module can also be configured as a combination of a first-stage reverse osmosis device and a second-stage reverse osmosis device, as required.

[0027] In one embodiment of the present application, the filtration module includes: a mechanical filter, an activated carbon filter, a softening filter and a precision filter; the water outlet of the raw water tank is connected to the water inlet of the mechanical filter, the water outlet of the mechanical filter is connected to the water inlet of the activated carbon filter, the water outlet of the activated carbon filter is connected to the water inlet of the softening filter, the water outlet of the softening filter is connected to the water inlet of the precision filter, and the water outlet of the precision filter is connected to the water inlet of the reverse osmosis module.

[0028] In this embodiment, a mechanical filter utilizes a filter medium to remove impurities such as suspended matter, colloids, and organic matter from water. As raw water flows through the filter layer within the filter, suspended matter and colloidal particles in the raw water are retained by the filter media, thereby reducing the turbidity of the raw water. An activated carbon filter, primarily filled with activated carbon, utilizes the adsorption properties of the activated carbon to remove impurities such as organic matter, oxides, residual chlorine, and some heavy metal ions from the raw water, while also reducing the color of the raw water. A softening filter utilizes an ion exchange resin to adsorb and decompose ions in the raw water, thereby reducing the hardness of the raw water. A precision filter utilizes the pores of a filter element (e.g., a polypropylene filter element) to mechanically filter, retaining or adsorbing trace suspended particles, colloids, microorganisms, and other impurities remaining in the raw water. It efficiently removes solid particles 0.01 μm and larger from the raw water and controls the oil mist concentration to below 0.01 ppm / wt. The raw water is sequentially filtered through the mechanical filter, activated carbon filter, softening filter, and precision filter, effectively removing impurities from the raw water and reducing its color, hardness, and oil mist concentration.

[0029] In one embodiment of the present application, the disinfection water treatment system also includes: a raw water pump, the water inlet end of the raw water pump is connected to the water outlet of the raw water tank, and the water outlet end of the raw water pump is connected to the water inlet of the mechanical filter.

[0030] In this embodiment, in the process of raw water flowing from the raw water tank to the mechanical filter, the raw water pump provides power for the transportation of raw water, meeting the flow requirements of raw water in the raw water tank flow, mechanical filter, activated carbon filter, softening filter, precision filter, and reverse osmosis module.

[0031] In one embodiment of the present application, the disinfection water treatment system also includes: an oxidation-reduction potential monitoring device and a proton exchange membrane ozone device; the oxidation-reduction potential monitoring device is arranged on the connecting pipeline between the water outlet of the ultraviolet sterilization device and the water inlet of the three-way valve, and is used to monitor the oxidation-reduction potential of the water in the connecting pipeline; the ozone output end of the proton exchange membrane ozone device is connected to the ozone input end of the pure water tank, and is used to be turned on when the oxidation-reduction potential monitoring result is unqualified.

[0032] In this embodiment, the redox potential monitoring device is used to online monitor the redox potential of the water in the connecting pipe. If the redox potential of the water in the connecting pipe is less than a preset redox potential threshold, the redox potential monitoring result is determined to be unqualified; if the redox potential of the water in the connecting pipe is greater than or equal to the preset redox potential threshold, the redox potential monitoring result is determined to be qualified. When the redox potential monitoring result is unqualified, the proton exchange membrane ozone device is activated, and the ozone generated by the proton exchange membrane ozone device is input into the pure water tank. The ozone disinfects and sterilizes the water in the pure water tank, removes organic matter, reduces water color, removes water odor, controls algae concentration, removes inorganic substances such as iron and manganese, as well as hydrogen sulfide and sulfide, thereby adjusting the redox potential of the water in the pure water tank.

[0033] In this embodiment, the conductivity monitoring device and the oxidation-reduction potential monitoring device select the water point position as the monitoring position on the connecting pipeline. If the conductivity monitoring result at the water point position is qualified and the oxidation-reduction potential monitoring result is qualified, it means that the water at the water point position can be used as terminal rinsing water; if the conductivity monitoring result at the water point position is unqualified and the oxidation-reduction potential monitoring result is qualified, the first water outlet is controlled to be opened and the second water outlet is closed, and the water in the connecting pipeline flows into the raw water tank and is filtered and disinfected again until the conductivity monitoring result of the water after re-treatment is qualified and the oxidation-reduction potential monitoring result is qualified; if the conductivity monitoring result at the water point position is unqualified and the oxidation-reduction potential monitoring result is unqualified, the first water outlet is controlled to be opened and the second water outlet is closed. The water inlet is closed, and the proton exchange membrane ozone device is turned on. The water in the connecting pipe flows into the raw water tank, and is filtered and disinfected again. The redox potential in the water is adjusted by the proton exchange membrane ozone device until the conductivity monitoring result of the water after the second treatment is qualified and the redox potential monitoring result is qualified. If the conductivity monitoring result at the water point is qualified and the redox potential monitoring result is unqualified, the first water outlet is controlled to be closed and the second water outlet is opened, and the proton exchange membrane ozone device is turned on. The water in the connecting pipe flows into the pure water tank, and the redox potential in the water is adjusted by the proton exchange membrane ozone device. The water in the pure water tank is sterilized by the ultraviolet sterilization device until the conductivity monitoring result of the water after the second treatment is qualified and the redox potential monitoring result is qualified. Through the dual monitoring of conductivity and redox potential, not only can the water at the water point be guaranteed to meet the standards for end-rinsing water, but also the treatment effect of the disinfection water treatment system is further improved.

[0034] In one embodiment of the present application, the disinfection water treatment system also includes: a controller and an alarm; the controller is wirelessly connected to the conductivity monitoring device, and is used to control the switching of the first water outlet and the second water outlet based on the conductivity monitoring result; the controller is wirelessly connected to the oxidation-reduction potential monitoring device, and is used to control the proton exchange membrane ozone device to turn on when the oxidation-reduction potential monitoring result is unqualified; the controller is wirelessly connected to the alarm, and is used to control the alarm to sound an alarm when the oxidation-reduction potential monitoring result is unqualified.

The controller is wirelessly connected to the conductivity monitoring device, which is convenient for real-time reception of the online monitoring results of the conductivity monitoring device. The controller is wirelessly connected to the redox potential monitoring device, which is convenient for real-time reception of the online monitoring results of the redox potential monitoring device. The controller is wirelessly connected to the alarm, which is convenient for sending alarm control signals to the alarm in real time to remind the staff to perform corresponding operations.

[0036] In this embodiment, when the online monitoring result of the conductivity monitoring device is qualified, the controller controls the first water outlet to close and the second water outlet to open; when the online monitoring result of the conductivity monitoring device is unqualified, the controller controls the first water outlet to open and the second water outlet to close, thereby realizing real-time control of the three-way valve by the controller.

[0037] In this embodiment, when the redox potential monitoring result is unqualified, the alarm is controlled to sound an alarm, the proton exchange membrane ozone device is started to sterilize and disinfect the water in the pure water tank, and the redox potential of the water in the pure water tank is adjusted, thereby affecting the redox potential of the water at the water use point, until the redox potential of the water at the water use point is greater than or equal to the preset redox potential threshold.

[0038] In this embodiment, the wireless connection method between the controller and the conductivity monitoring device includes Bluetooth, WiFi (Wireless Fidelity), etc., the wireless connection method between the controller and the oxidation-reduction potential monitoring device includes Bluetooth, WiFi, etc., and the wireless connection method between the controller and the alarm includes Bluetooth, WiFi (Wireless Fidelity), etc.

[0039] In one embodiment of the present application, the disinfection water treatment system further includes: a circulation pump, the water inlet of the circulation pump is connected to the water outlet of the pure water tank, and the water outlet of the circulation pump is connected to the water inlet of the ultraviolet sterilization device.

[0040] In this embodiment, the circulating pump provides power for the water flowing out of the pure water tank, so that the water flowing out of the pure water tank flows into the pure water tank or the raw water tank through the ultraviolet sterilization device.

The water in the pure water tank is transported by the circulation pump, sterilized by the ultraviolet sterilization device, and reaches the water point. The water at the water point is monitored for conductivity and redox potential. If the conductivity monitoring result is qualified and the redox potential monitoring result is unqualified, the water at the water point flows back to the pure water tank and the proton exchange membrane ozone device is started intermittently. The proton exchange membrane ozone device ionizes part of the water molecules to produce ozone molecules, which sterilizes the microorganisms in the water in the pure water tank, thereby regulating the oxygen content of the water in the pure water tank. The redox potential of the water in the pure water tank is adjusted, thereby affecting the redox potential of the water at the water use point, until the conductivity monitoring result of the water at the water use point is qualified and the redox potential monitoring result is qualified; when the conductivity monitoring result is unqualified and the redox potential monitoring result is unqualified, the water at the water use point flows back to the raw water tank and the proton exchange membrane ozone device is started intermittently.
