Abstract

PURPOSE:To perform oxidative decomposition of org. compds. contained in water, sterilization of general bacteria and colibacillus, removal and deodorization by decomposition of residual chlorine, effectively, by mixing ozone in circulating water and irradiating the circulating water effectively with ultraviolet rays. CONSTITUTION:An ultraviolet ray source 12 is installed to an external pipe 13 housed in the inside of a main body 11 of the water treating apparatus and a nozzle 14 is provided to the top of the ultraviolet ray source 12. Further a mixture of water with ozone is ejected from the nozzle 14 and circulated between the main body 11 of the apparatus and the nozzle 14. For example, when city water 20 is injected into the apparatus and the ultraviolet ray source 12 is lit and a pump 16 is driven, the ozone in the external pipe 13 is mixed with the circulating water and ejected around the ultraviolet ray source 12. The circulating water is irradiated with the ultraviolet rays from its source 12, thus, oxidative decomposition of org. compds. in the water, sterilization of general bacteria and colibacillus, and removal and deodorization by decomposition of residual chlorine are performed effectively.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the improvement of water treatment equipment, and particularly to the improvement of water treatment equipment, which oxidizes and decomposes organic compounds contained in water, sterilizes general bacteria and Escherichia coli, and protects humans and water. The present invention relates to a device that can obtain drinking water for storage or water suitable for cultivating fish and shellfish.

[Prior art and its problems]

In recent years, for example, the organic compounds contained in water can be removed by irradiating drinking water for humans, water storage, or aquaculture water for fish and shellfish with ultraviolet rays using an ultraviolet light source and mixing ozone, which is generated in large quantities with ultraviolet light sources. It is oxidized and decomposed, sterilizes general bacteria and E. coli, and decomposes and removes residual chlorine.

For example, as shown in Fig. 2, the conventional processing equipment is
A lamp house 3 having an air intake hole 2 is attached to the lower end of the power supply house 1, an ultraviolet light source 4 is attached inside the lamp house 3, and the same device is attached to the upper part of a T-shaped water pipe 50, and the water pipe The structure is such that the water flowing through the tank is irradiated with ultraviolet rays and ozonized air is mixed therein.

However, according to this device, since the water flowing through the water pipe 5 is irradiated with ultraviolet rays through the hollow part of the lamp house 3, the irradiation rate of ultraviolet rays to the water is low, and the ultraviolet light source enters through the air intake hole 2, causing ozonation. Since the ozonized gas is naturally mixed into the water flowing through the water pipe 5 below, the proportion of ozonized gas mixed into the water is low, and the oxidative decomposition of organic compounds contained in the water and general bacteria are reduced. Disadvantages include low effectiveness in sterilizing E. coli and decomposing and removing residual chlorine.

[Purpose of the invention]

The present invention was invented in view of the above points, and is a water treatment device that can effectively perform oxidative decomposition of organic compounds contained in water, decomposition and removal of residual chlorine for disinfection of general bacteria and Escherichia coli, etc. The purpose is to provide

[Means for solving problems]

The present invention will be explained below with reference to FIG.

In the figure, reference numeral 11 denotes the main body of the apparatus, which is made of, for example, stainless steel and has a cylindrical shape. Reference numeral 12 denotes an ultraviolet light source housed in an outer tube 13 that transmits ultraviolet light, and is, for example, a 12 watt one-time source and housed inside the main body 11 of the apparatus.

Reference numeral 14 denotes a nozzle provided above the ultraviolet light source 12, and is configured to eject a mixture of ozone and water. 15 has one end connected to a part of the nozzle 14 in communication,
A pipe 16 whose other end is connected to the lower part of the device main body 11
is a pump provided in the middle of a part of the pipe 15,
The structure is such that the water in the main body 11 of the apparatus is circulated again to the nozzle 14. 1T is a pipe having one end connected to the outer tube 13 and one end connected to a part of the nozzle 14, which sends ozone generated from the ultraviolet light source 12 in the outer tube 13 to the nozzle 14 and mixes it with water. It is constructed to eject into the water. Reference numeral 18 denotes a treated water outlet, and 19 a plate provided to prevent tap water from being directly sent out from the outlet 18.

[Action of the invention]

Inject water into the above-mentioned water treatment equipment K, for example, tap water 20f, turn on the ultraviolet light source 12, and operate the pump 16tl.

When the ozone is moved, the ozone in the outer tube 13 heats up with the circulating water and is ejected around the ultraviolet light source 12.
By irradiating circulating water with ultraviolet rays, it can effectively oxidize and decompose organic compounds in water, sterilize general bacteria and E. coli, decompose and remove residual chlorine, and deodorize water.

〔Effect of the invention〕

As described above, the present invention includes an ultraviolet light source housed in an outer tube inside the main body of the device, and a nozzle provided above the ultraviolet light source. Since the structure is such that water is ejected into the water and circulated between the device body and the nozzle, as mentioned above, ozone is mixed into the circulating water, and furthermore, ultraviolet rays are emitted by a! l3I
Effectively irradiates water to oxidize and decompose organic compounds in water, sterilize general bacteria and E. coli, and decompose and remove residual chlorine.
It has the advantage of being able to effectively remove odors and having great utility value as drinking water for humans and water reserves, or breeding water for fish and shellfish.
