It is formed, and on the other side, a discharge pipe 12 for supplying water by connecting to a place of use is formed to communicate with the inside at a position that keeps the water level constant.

That is, ozone gas and water are simultaneously introduced into the chamber 10 through the inlet pipe 11, sterilized by OH radicals, and then discharged from the chamber 10 through the outlet pipe 12.

An air vent tube 13 is installed at the top of the chamber 10 to allow excess ozone gas and oxygen to escape.

In addition, a drain hole 14 may be formed at the lower end of the chamber 10, and a valve for opening and closing may be installed in the middle of the pipe of the drain hole 14, of course.

Here, the inlet pipe 11 and the outlet pipe 12 are preferably formed of flanged pipes that have flanges at their ends for connection with other pipes and can be tightened with bolts and nuts.

In addition, the inner circumference of the chamber 10, that is, the inner wall, can be coated with a reflective paint such as aluminum paint or polished to increase the reflectance of the ultraviolet light emitted from the ultraviolet lamp 30, thereby maximizing the irradiation efficiency.

A plurality of quartz tubes 20 are arranged at regular intervals in the chamber 10 to isolate and protect the UV lamp 30 from contact with water.

That is, the quartz tube 20 is formed long along the vertical length direction of the chamber 10 .

The ultraviolet lamp 30 is embedded in the quartz tube 20 to emit ultraviolet rays for sterilizing microorganisms and bacteria in the water.

Here, OH radicals generated in the process of reacting ultraviolet rays with a wavelength of 0.1 to 400 nm emitted from the ultraviolet lamp 30 with water and dissolved oxygen are used to sterilize various bacteria, fungi, and viruses, and decompose and remove pollutants and odors can do.

In addition, it goes without saying that the UV lamps 30 may be installed with different lengths or increased in quantity according to the processing capacity of the chamber 10 .

The mixing pipe 40 has its upper end communicated with the inlet pipe 11 in order to send it to the lower part of the chamber 10 in a state where the particles of the ozone gas supplied through the inlet pipe 11 are reduced to maximize the contact efficiency with water. It is arranged in the central part in the chamber 10 while being connected.

Specifically, the mixing pipe 40 is formed in a structure in which a plurality of funnels 42 are inserted and mounted in multiple stages in at least three layers inside a pipe 41 having a certain length vertically.

And the funnel 42 is formed in the shape of a cone with a wide upper part and a narrow lower part, and holes of different sizes are formed around it in an irregular arrangement so that ozone gas and water pass through.

Here, it is preferable that the gas discharge device 60 adopts a structure in which power supply is not required and ozone gas and oxygen in the chamber 10 are automatically discharged but water is not discharged.

In addition, an ozone eliminator 70 is installed to decompose the ozone gas discharged through the gas discharger 60 into carbon dioxide using a special catalyst and then discharge it to the atmosphere.

The main actions and operating principles of the sterilization and purification device for a water treatment system according to an embodiment of the present invention configured as described above are as follows.

First, the injector (I) flows the ozone gas generated in the ozone generator (O) at a high speed through the inlet pipe (11) of the chamber (10), sucks in the filtered water from the filter (F), mixes it, and ejects it at high pressure. When connected through a pipe, ozone gas and water are supplied through the inlet pipe 11 with the pressure of the injector I and pass through the mixing pipe 40 in the chamber 10.

At this time, the ozone gas and water passing through the mixing pipe 40 repeatedly pass through rapidly and slowly, causing a vortex phenomenon. It is sent to the lower part of the chamber 10, that is, to the lower space of the perforated plate 50, with the contact efficiency maximized.

Subsequently, the micronized ozone gas and water rise from the lower part of the chamber 10 to the upper part and pass through the perforated plate 50 step by step, while being supplied to the water (underwater) in the chamber 10 in a second ultra-fine state.

That is, ozone gas and water rise due to the blade 51 and the hole 52 formed by punching an irregular sawtooth shape in the perforated plate 50 and lifting it up at an acute angle or twisting it in the front and rear or left and right directions. The passage speed (flow rate) increases according to the perforated plate 50 and the process of slowing down when passing between the perforated plate 50 and the other perforated plate 50 occurs repeatedly, and the fine particles of ozone gas are dispersed like fog in a smaller size. Since the contact area with water is increased, the ozone dissolution rate can be maximized.

Subsequently, the ultrafine ozone gas dispersed and dissolved in the water rises and reacts with the ultraviolet light irradiated from the ultraviolet lamp 30 to decompose to generate OH radicals having strong oxidizing power.

Since these OH radicals have a stronger potential difference (3.08V) than ozone, they can sterilize various bacteria, viruses, and harmful microorganisms in water by exerting stronger sterilization power than ozone, and decompose organic matter to purify and efficiently remove odors.

Therefore, it is possible to circulate and supply water in a fresh and clean sterilized and purified state to a water use point such as a fountain or water play facility, thereby maintaining a more hygienic and clean environment and effectively preventing water-borne diseases.

On the other hand, the present invention is not limited by the above-described embodiments (embodiment) and the accompanying drawings, and can be variously modified and applied in various ways not illustrated within the scope without departing from the technical spirit of the present invention, as well as each It is clear to those of ordinary skill in the art that the components can be widely applied by substitution of components and changes to other equivalent embodiments.
