Abstract

PURPOSE:To remove odor and to decompose org. compds. effectively by forming ozone with plural sterilizing light sources provided to the inside of a water treating tank, collecting the ozone in a gas collecting pipe and dissolving in water through a gas feeding pipe. CONSTITUTION:A stirring machine 8 is driven at the same time with injection of feed water such as city water to a treating tank 2, and ozonized gas is introduced from a suction cylinder 4, and ultraviolet lamps 7 are lit. Thus, the ozonized gas is mixed with water and contacts therewith to perform deodorization and decomposition of org. compds. by the strong oxidizing effect of the ozone. Furthermore, bacteria contained in the water is sterilized by the ozone and the ultraviolet lamps 7. On one hand, the ozone generated from plural numbers of ultraviolet lamp 7 is collected in a gas collecting pipe 3, which is introduced into water through a suction cylinder 4 interposing a branch pipe 5, performing sterilization and deodorization similarly. By this method, treated water having good quality is obtd.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to improvements in water treatment equipment, and particularly to equipment capable of removing harmful components contained in water.

[Conventional technology]

Generally, water contains plankton and organic compounds that cause odors, and organic compounds in particular have a negative impact not only on odors but also on the human body.

Conventionally, there is a method of deodorizing by passing water through activated carbon and using the adsorption effect of activated carbon, or a method of deodorizing by the chemical action of ozone.
Sterilization methods are being used.

However, according to the method using activated carbon, when the adsorption capacity of activated carbon reaches the saturation point, it is necessary to replace the activated carbon.
If the activated carbon is not replaced, Escherichia coli, general bacteria, etc. will breed on the activated carbon.

In addition, according to the method of deodorizing or sterilizing by the chemical action of ozone, when a general silent discharge ozonizer is used to generate ozone, nitrogen oxides are produced as a by-product in the process of ozonizing the air, and the treated water is It has the disadvantage that it is mixed in as an impurity.

[Purpose of the invention]

The present invention was invented in view of the above points, and an object of the present invention is to provide a water treatment device that can deodorize the odors contained in water and effectively decompose organic compounds that have an adverse effect on the human body. purpose.

[Structure of the invention]

The invention will now be described with reference to FIGS. 1 and 2. 1
Reference numeral 2 denotes a box-shaped water treatment apparatus main body, and 2 a treatment tank housed inside the water treatment apparatus main body, which is made of, for example, stainless steel.

Reference numeral 3 denotes an ozone air collection pipe provided above the processing tank 2, and 4 represents an integral suction tube communicating with the ozone air collection pipe 3, which is configured to be perpendicular to the inside of the processing tank 2. Chiru. Reference numeral 5 designates a branch pipe integrally provided in communication with a part of the suction tube 4, and reference numeral 6 designates a lamp storage pipe provided with its lower end located toward the bottom of the processing tank 2 and its upper end communicated with the ozone collection pipe 3. Numerals 1 and 7 are sterilizing light sources disposed inside the lamp housing tube 6, and are configured by providing a plurality of light sources, for example, the amount of water 4.
It uses an ultraviolet lamp of 40 watts per liter of water, and is designed to sterilize E. coli and other bacteria contained in the water. Reference numeral 8 denotes a stirrer provided at the lower end of the suction cylinder 4, and is configured to be rotated by a motor 9 provided at the upper part of the suction cylinder 4.

Reference numeral 10 denotes an ore layer located in the upper part of the water in the processing tank 2, and the ore layer 10 is located in the center of ores such as kloanite, feldspar, mica, granite, quartz, igneous rock, metamorphic rock, sedimentary rock, and volcanic rock. It consists of at least one type. 11 A filter provided in a part of the lid body 12 of the processing tank 2,
It is constructed using activated carbon. Reference numeral 13 denotes a level sensor installed above the inner end of the processing tank 2, and is configured to send a signal to the electromagnetic valve 14 when the amount of water in the processing tank 2 falls below a predetermined amount. 15 is a drain cock, 16 is a light source fault detector, 17 is a water injection hole, and 18 is a water outlet hole.

Next, the processing in the water treatment apparatus described above will be explained.

■ Pour tap water, for example, into the treatment tank 2 described above:
, :1171: At the same time, the stirrer 8 is rotated.≠ All ozonized gas is fed from the suction tube 4, and the ultraviolet lamp T is turned on.

■ According to such a device, the water is stirred by the stirrer 8, and the ozonized gas sent from the suction tube 4 comes into contact with the water, deodorizes it due to the strong oxidizing power of ozone, and also causes cancer. It is possible to carry out oxidative decomposition treatment of the original organic compounds (particularly organic chlorine compounds), and also to sterilize bacteria contained in the water using ozone and a sterilizing light source.

In particular, according to the device according to the invention, a plurality of sterilizing light sources are used, so that when a certain amount of air is sent into the water, the air passing through the one sterilizing lamp housing tube is The amount of ozone produced by each sterilizing light source increases accordingly (the amount of ozone produced is inversely proportional to the amount of air aeration). 1. It can effectively perform sterilizing action.

Furthermore, since a plurality of sterilizing light sources are used and dispersed in the water, the rate of irradiation of water with ultraviolet rays can be improved and the sterilizing effect can be enhanced.

■ It is also deodorized, sterilized, and stirred by the stirrer 8.
@lt-Contained water passes through while contacting the ore layer 10,
When water passes through the ore layer 10, bubbles in the water burst,
Due to the ultrasonic components generated as the bubbles burst, the chemical components contained in the ore are turned into minerals and eluted into the water, making it possible to easily obtain mineral water.

If the water treatment equipment is stopped for several tens of hours, general bacteria may grow in the ore layer, but by restarting the water treatment equipment, the high concentration of ozone collected in the air collection pipe can effectively sterilize the bacteria. I can do it.

〔Effect of the invention〕

As described above, the present invention is capable of sterilizing bacteria contained in water by disposing a plurality of sterilizing light sources inside a water treatment tank and using ozone generated from the sterilizing light sources. Ozone generated from a sterilizing light source is collected in an air collection pipe, and then the highly concentrated ozone is dissolved into water through the air pipe, and ozone's strong oxidizing power eliminates the odor of the water, and further oxidizes and decomposes organic compounds. It can be carried out effectively and high-quality treated water can be obtained, which is highly useful as drinking water or water for food processing.
