The reverse osmosis membrane is an artificial semi-permeable membrane with specific characteristics, mimicking a biological semi-permeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis is that, under pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating them from water. The reverse osmosis membrane has very small pores, effectively removing dissolved salts, colloids, microorganisms, and organic matter from the water. The system has advantages such as good water quality, low energy consumption, no pollution, simple process, and easy operation. The raw water tank 1 and the quartz sand filter... A raw water pump 2 is installed between filters 3. The raw water pump 2 is a CHL horizontal water supply pump. The input end of the raw water pump 2 is connected to the raw water tank 1.

[0023] When instrument cleaning is required, water in instrument cleaning water tank 10 passes through flow-through UV sterilizer 12, and then water supply pumps 14 and 25 are turned on to send the water through microporous filter 18 to water terminal 20. When performing surgical scrubbing, the switch at water terminal 21 is turned on, and water in surgical scrubbing water tank 11 passes through flow-through UV sterilizer 23, and then water supply pumps 3 and 4 work together to send the water through microporous filter 29 to water terminal 21. Branch water treatment mechanism 1 and branch water treatment mechanism 2 are respectively set between instrument cleaning water tank 10 and water terminal 20, and between surgical scrubbing water tank 11 and water terminal 21. The independent setting of the two branch water treatment mechanisms ensures that there is no mutual interference between water terminal 20 and water terminal 21.

This process is used for instrument cleaning. When cleaning the instrument cleaning water tank 10 and the surgical scrubber water tank 11, ozone generator 1 22 and ozone generator 23 are used in conjunction with the jet injector. The generated ozone is injected into the water through the jet injector to clean the instrument cleaning water tank 10 and the surgical scrubber water tank 11. The water used to clean the instrument cleaning water tank 10 and the surgical scrubber water tank 11 is treated by branch water treatment unit 1 and branch water treatment unit 2, thereby ensuring the cleaning effect of the instrument cleaning water tank 10 and the surgical scrubber water tank 11.

This is to control the switching of the above equipment and provide overload protection, effectively improving the stability of the system during water treatment.

[0027] Working principle: This device stores tap water in raw water tank 1 for later use. When in use, the raw water pump 2 introduces the water in raw water tank 1 into quartz sand filter 3 and activated carbon filter 4 for initial filtration. After passing through softener 5 and security filter 7, the treated water enters the first-stage reverse osmosis module 9 under the action of high-pressure pump 8. The produced water then enters instrument cleaning water tank 10 and surgical scrubbing water tank 11 respectively.

[0028] When instrument cleaning is required, water from instrument cleaning water tank 10 passes through flow-through UV sterilizer 12, and then water supply pumps 14 and 25 are turned on to deliver the water through microporous filter 18 to water terminal 20. When performing surgical scrubbing, the switch at water terminal 21 is turned on, and water from surgical scrubbing water tank 11 passes through flow-through UV sterilizer 23, and then water supply pumps 3 and 4 work together to deliver the water through microporous filter 29 to water terminal 21. Branch water treatment mechanisms 1 and 2 are respectively installed between instrument cleaning water tank 10 and water terminal 20, and between surgical scrubbing water tank 11 and water terminal 21.

Ozone is installed on the outside of branch water treatment mechanisms 1 and 2 respectively. Ozone generator 1 (22) and ozone generator 2 (23) are used in conjunction with an ejector to clean the instrument cleaning water tank 10 and the surgical scrubber water tank 11. The generated ozone is injected into the water through the ejector to clean the instrument cleaning water tank 10 and the surgical scrubber water tank 11. The water used to clean the instrument cleaning water tank 10 and the surgical scrubber water tank 11 is treated by branch water treatment unit 1 and branch water treatment unit 2, thus ensuring the cleaning effect of the instrument cleaning water tank 10 and the surgical scrubber water tank 11. After cleaning, ozone generator 1 (22) and ozone generator 2 (23) are turned off, and the wastewater is discharged and collected by wastewater collection device 24. After being treated by wastewater treatment device 25, it is discharged through discharge pipe 26. At the same time, the drain ends of water terminal 1 (20) and water terminal 2 (21) are connected to wastewater collection device 24 for easy wastewater collection.
