The water inlet end of gas-water mixer 3 is connected to pure water circulation pipe 1 through water inlet pipe 21. The pure water in pure water circulation pipe 1 is transported to gas-water mixer 3 through water inlet pipe 21 and mixed with ozone. The finally mixed ozone water is stored in ozone water tank 23. Ozone water can also be prepared while being disinfected. Ozone water in ozone water tank 23 is transported to pure water circulation pipe 1 by ozone circulating pump 6 to achieve ozone disinfection.

[0026] Ozone has strong oxidizing ability and can effectively kill bacteria, viruses, fungi and protozoa and other microorganisms. Its bactericidal effect is more extensive and thorough than that of ultraviolet light. Ozone decomposes into oxygen in water and does not leave chemical residues in water.

[0027] Ozone not only can kill microorganisms, but also can oxidize and decompose organic matter in water, further improve water quality, ozone disinfection reaction speed is fast, can achieve high efficiency disinfection effect in short time, operation is simple.

[0028] Ozone detector is installed between the water inlet end of gas-water mixer 3 and pure water circulation pipe 1 to detect the concentration of ozone water flowing out of pure water circulation pipe 1 and feedback the concentration of ozone water in pure water circulation pipe 1. Ozone detector can also be designed between gas-water mixer 3 and ozone water tank 23, or directly installed in ozone water tank 23 at the water outlet end to monitor the ozone concentration in mixed ozone water in real time.

[0029] Further, check valve 901 and ball valve 902 are installed at the water inlet end of water inlet pipe 21.

[0030] The main function of check valve 901 is to prevent water flow from flowing in reverse direction, and ball valve 902 can be used to control the opening and closing of water flow and adjust the flow.

[0031] In some embodiments, the water replenishment end of the ozone water tank 23 is connected to a water replenishment pipe 7, which is connected to the water outlet pipe 22, and a valve assembly 8 is installed on the water replenishment pipe 7. The valve assembly 8 is provided with an inlet valve and a ball valve 902.

By adjusting the opening of the ball valve 902, the flow of water replenishment can be accurately controlled, ensuring that the water level in the ozone water tank 23 remains within the appropriate range.

[0033] In some embodiments, a safety valve 903 and a pressure gauge 904 are provided near the water inlet end of the gas-water mixer 3.

[0034] The safety valve 903 is used to automatically release pressure when the pressure in the water inlet pipe 21 exceeds the set value, preventing damage to the pipeline or gas-water mixer 3 due to overpressure, and avoiding potential dangers. The set pressure of the safety valve 903 should be selected according to the working pressure and safety requirements of the system.

[0035] The pressure gauge 904 is used to display the pressure value of the water inlet pipe 21 in real time. By monitoring the readings of the pressure gauge 904, the operator can understand the running state of the system and timely find abnormal conditions such as excessive or insufficient pressure, so as to take corresponding measures to avoid accidents. The range of the pressure gauge 904 should be selected appropriately to ensure accurate reflection of the pressure changes of the system.

[0037] Further, a check valve 901 and a ball valve 902 are installed on the water outlet pipe 22 near the water outlet end of the circulating pump.

[0038] The check valve 901 is used to prevent the water in the system from flowing back to the circulating pump after the circulating pump stops working, protecting the circulating pump from the impact and damage of reverse water flow. The ball valve 902 is mainly used to conveniently control the start and stop of the circulating system and adjust the water flow.

[0039] In some embodiments, a liquid level transmitter 905 is installed at the bottom of the ozone water tank 23.

[0040] The liquid level transmitter 905 can detect the change of the liquid level in the ozone water tank 23 and convert it into an electrical signal, which is fed back to the control system in real time. By monitoring the liquid level of the ozone water tank 23 in real time through the liquid level transmitter 905, the possibility of excessive or insufficient liquid level can be avoided, ensuring the safe and stable operation of the system.

[0041] In some embodiments, a sampling valve 906 is installed on the outlet pipe 22 and the inlet pipe 21.

[0042] The sampling valve 906 can be used for regular or irregular sampling to detect whether the water quality after mixing ozone meets the requirements and ensure the effectiveness of the treatment system. The sampling valve 906 installed on the outlet pipe 22 is used to detect the water quality after treatment by the ozone machine 5 and the gas-water mixer 3. The sampling valve 906 installed on the inlet pipe 21 is used to detect the quality of pure water entering the gas-water mixer 3.

[0043] Further, the sampling valve 906 is arranged near the water inlet end of the gas-water mixer 3.

[0044] In some embodiments, the pure water circulation pipe 1 is provided with a sampling valve 906 and a constant pressure valve 907. The sampling valve 906 and the constant pressure valve 907 are arranged near the end of the inlet pipe 21, and the sampling valve 906 and the constant pressure valve 907 are designed with a pressure gauge 904.

[0045] The sampling valve 906 is used to detect the water quality in the pure water circulation pipe 1, and the constant pressure valve 907 is used to maintain the stability of the pressure in the pure water circulation pipe 1. The constant pressure valve 907 can automatically adjust the valve opening according to the water consumption of the system to ensure that the pressure in the pipeline is constant at a set value, which can avoid system instability caused by pressure fluctuations.

[0046] Further, the bottom of the ozone water tank 23 is connected to a drain pipe, and a drain valve 908 is installed on the drain pipe.

[0047] The ozone water tank 23 needs to be cleaned and maintained regularly to remove possible accumulated dirt, sediment or biofilm to prevent affecting the efficiency of the ozone generator and the water quality.

[0048] The drain valve 908 facilitates the drainage operation during cleaning. During system shutdown maintenance or repair, the water in the ozone water tank 23 needs to be completely drained to facilitate repair work.

[0049] During use, there may be a small amount of residual liquid at the bottom of the ozone water tank 23, and the drain valve 908 can conveniently drain the residual liquid to avoid waste and pollution.
