The outlet of the raw water tank 11 and the inlet of the raw water pump 12 are connected by a pipe. The outlet of the raw water pump 12 and the inlet of the quartz sand 13 are connected by a pipe. The outlet of the quartz sand 13 and the inlet of the activated carbon 14 are connected by a pipe. The outlet of the activated carbon 14 and the inlet of the softener 15 are connected by a pipe. The softener 15 is connected to a brine tank 19 by a pipe. The outlet of the softener 15 and the inlet of the security filter 16 are connected by a pipe. The outlet of the security filter 16 and the inlet of the high-pressure pump 17 are connected by a pipe. The outlet of the high-pressure pump 17 and the inlet of the first-stage reverse osmosis module 18 are connected by a pipe.
[0023] The raw water pump 12 can be a CHL horizontal water supply pump. The raw water tank is made of 304 stainless steel and has a built-in level sensor (not shown in the figure). When the water level in the tank reaches a certain height, the water inlet system will stop operating, and when the water level drops to a certain height, the raw water pump will stop operating. The quartz sand 13 consists of a quartz sand filter tank and quartz sand filter media, and the filter tank is made of 304 stainless steel. The activated carbon 14 consists of an activated carbon filter tank and activated carbon filter media, and the filter tank is made of 304 stainless steel. The softener 15 consists of a softening filter tank and softening resin. The filter tank is made of 304 stainless steel. The softening resin is a special resin used to soften hard water. The brine tank 19 consists of a brine tank and regenerated salt. The brine tank is made of PE material. When the softener 15 is backwashed, it can reduce the resin by absorbing the reducing agent in the brine tank 6. The security filter 16 consists of a cylindrical shell and built-in filter elements. The cylindrical shell is made of 304 stainless steel. The filter elements are usually tubular filter elements such as PP melt-blown, wire-burned, pleated, titanium filter elements, and activated carbon filter elements. The first-stage reverse osmosis module 18 consists of a reverse osmosis membrane and a reverse osmosis membrane shell.
[0024] The cleaning water treatment system 2 includes a rinsing and cleaning water tank 21, a flow-through UV sterilizer 22, a water supply pump 23, a microporous filter 24, an endoscope end filter 25, and a water terminal 26. Two water supply pumps 23 are provided. The inlet of the rinsing and cleaning water tank 21 and the outlet of the first-stage reverse osmosis module 18 are connected by a pipe.

The outlet of the endoscope end filter 25 and the inlet of the water terminal 26 are connected by a pipe.
[0025] The rinsing and cleaning water tank 21 is made of 304 stainless steel and has a built-in level sensor. Water production will stop when the softened water level in the tank reaches a certain height, and water supply will stop when the level drops to a certain height. The water supply pump 23 detects the actual water pressure value through a controller (PLC control cabinet 5), compares the set water pressure value with the actual water pressure value, calculates the difference according to the PID control law, and outputs a control signal to the frequency converter. The frequency converter then adjusts the power supply voltage and frequency of the pump motor according to the input signal from the controller. When water consumption increases, the controller controls the frequency converter to increase the motor voltage and frequency, increasing the pump speed and water output; when water consumption decreases, the controller controls the frequency converter to decrease the motor voltage and frequency, decreasing the pump speed and water output. This control method allows the water supply pipe pressure to be maintained at a set value. The microporous filter 24 consists of a cylindrical outer shell and built-in filter elements. The outer shell is made of 304 stainless steel, and the filter elements are typically tubular filter elements such as PP melt-blown, wire-spun, pleated, titanium, and activated carbon filters. The end-filter 25 is mainly used to capture particulate dust and various suspended solids larger than 0.2µm, serving as the final filter in various filtration systems. It uses ultra-fine glass fiber paper as the filter media, folded paperboard, aluminum foil, and other materials as dividing plates, sealed with a new type of polyurethane sealant, and constructed with galvanized steel, stainless steel, or aluminum alloy profiles as the outer frame.
[0026] The water outlet of the water terminal 26 is connected to each cleaning water device through a pipe. Each cleaning water device is connected to the rinsing water tank 21 through a pipe, and an ozone generator 28 and a jet injector 27 are connected to the pipe.
[0027] When the inside of the flushing water tank 21 needs to be cleaned, the water at the water terminal 26 flows back to the flushing water tank 21 through the pipeline. Then, the inside of the flushing water tank 21 is cleaned by the cooperation of the ozone generator 28 and the jet injector 27. After cleaning, the sewage is discharged and then the cleaning water is introduced into the flushing water tank 21 for another flush. After emptying, softened water can be refilled for continued use.

[0029] The acidified water replenishment tank 31 is made of 304 stainless steel and has a built-in liquid level sensor. When the softened water in the tank reaches a certain level, the water production will stop, and when the liquid level drops to a certain level, the water supply will stop. The acidified water machine 35 is an acidic solution with low concentration of available chlorine, high oxidation-reduction potential, and hypochlorous acid as the main active ingredient, generated from the anode side after electrolysis of pure water with added low concentration of sodium chloride (solution concentration less than 0.1%) in an ion-exchange membrane electrolysis cell. The water supply pump 2 33 and water supply pump 1 23 have the same structure and function, and the microporous filter 2 34 and microporous filter 1 24 have the same structure and function, which will not be described in detail here.
[0030] The wastewater treatment system 4 includes a hospital wastewater collection pipeline 41. The outlet pipe of the hospital wastewater collection pipeline 41 is connected to a wastewater treatment device 42. The outlet pipe of the wastewater treatment device 42 is connected to a discharge pipe 43. Wastewater used in various departments of the endoscopy center can be introduced into the wastewater treatment device 42 through the pipeline and the hospital wastewater collection pipeline 41 for wastewater treatment. After the wastewater meets the standards, it can be discharged through the discharge pipe 43.
[0031] Working principle:
[0032] The raw water inside the raw water tank 11 is pumped out by the raw water pump 12 and filtered sequentially by the quartz sand 13, activated carbon 14, softener 15 and security filter 16. Then, the filtered water is further introduced into the first-stage reverse osmosis module 18 for further treatment by the high-pressure pump 17. After the central water treatment system 1 has treated the raw water, it is then distributed to the cleaning water treatment system 2 and the acidification water treatment system 3.
[0033] Water flowing into the cleaning water treatment system 2 first enters the flushing water tank 21. When the water supply pump 23 draws the water, it is sterilized by the flow-through UV sterilizer 22. After sterilization, the water passes through the microporous filter 24 and the endoscope end filter 25 in sequence before finally being directed to the water terminal 26. The water terminal 26 supplies the available water to the various cleaning water equipment in the department. When the inside of the flushing water tank 21 needs to be cleaned, the water at the water terminal 26 flows back to the flushing water tank 21 through the pipeline. Then, the inside of the flushing water tank 21 is cleaned by the cooperation of the ozone generator 28 and the jet nozzle 27. After cleaning, the wastewater is discharged and then rinsed again by introducing cleaning water into the flushing water tank 21. After emptying, softened water can be refilled for continued use.
[0034] Water flowing into the acidified water treatment system 3 first enters the acidified water replenishment tank 31. When the water supply pump 2 33 is pumped out, the water is sterilized by the flow-through UV sterilizer 2 32. After sterilization, the water passes through the microporous filter 2 34 and the acidified water machine 35 in sequence before finally being directed to the acidified water use point 36. The acidified water use point 36 supplies usable water to each acidified water use device in the department.
[0035] Wastewater from the cleaning and acidification water equipment in the department can be piped to the hospital sewage collection pipeline 41. The sewage collection pipeline 41 then collects the wastewater and directs it to the sewage treatment equipment 42 for water treatment. The treated water is then discharged through the discharge pipeline 43.
