Description

Water purification device and water purification method for household water {omitted}

The present invention relates to a water purification device and a water purification method for household water, and more particularly, household water which can use clean water at home by removing not only various biological contaminants but also harmful metal contaminants such as heavy metals. It relates to a water purification device and a water purification method of the.

In general, tap water supplied to homes contains a large amount of biological impurities such as viruses and microorganisms and metal impurities caused by corrosion of water pipes.

Therefore, in general households, the above-mentioned biological impurities are used as drinking water at home after removing impurities using a water purifier employing a separate water filter, such as ordinary activated carbon, and the like. there was.

In addition, general household household water was used because it contained impurities without purified water.

Typically, when ultraviolet rays are irradiated to a photocatalyst such as titanium oxide, holes and electrons are generated on the surface of the photocatalyst in the electron band and the progress band, and the generated electrons and the major electrons electrochemically adsorb heavy metal ions and oxygen. Afterwards, the heavy metal ions are photoreduced or produce superroside radicals, which directly decompose the organic material and oxidize the organic material adsorbed on the surface of the photocatalytic particles.

However, the conventional household water purifier has a problem that it is not possible to remove metal harmful substances such as heavy metals contained in tap water, and the general living water is used without being purified, causing ohm salts on the skin by impurities, which is harmful to health.

Normally, when ultraviolet rays are irradiated to a photocatalyst such as titanium oxide, holes and electrons are generated on the surface of the photocatalyst in the electromagnetic band and the progress band, and the generated electrons and the major electrons electrochemically adsorb heavy metal ions and oxygen. Afterwards, the heavy metal ions are photoreduced or produce superroside radicals, which directly decompose the organic material and oxidize the organic material adsorbed on the surface of the photocatalytic particles.

In addition, ozone is a gas formed by combining three oxygen atoms, and exists in a very unstable form. It is strongly oxidized to other substances and changes to a stable state. It has an excellent effect on sterilization and deodorization. Low concentrations of ozone, which are harmful but do not exceed atmospheric environmental standards (0.1 ppm / h), are useful for humans.

The present invention has been made to solve the conventional problems as described above, the object of the present invention by using the photocatalyst and ozone in the raw water supplied to the home as well as biological contaminants contained in the raw water as well as harmful metal contaminants In addition, by injecting a small amount of ozone to improve the quality of the purified water and to provide not only drinking water, but also to provide purified water and home water purification method for household water that can supply purified domestic household water without a separate water treatment device.

In order to achieve the object of the present invention as described above, the water purification device and water purification method of household water of the present invention includes a treatment device for purifying raw water supplied to a home; An ejector provided in a raw water supply pipe through which a raw water is supplied through a first valve and receiving ozone generated from a normal ozone generator through a check valve to supply a raw water supply pipe, and receives ozone from the ejector therein.

In addition, in the filtration step, the aeration step of aeration of the remaining ozone collected in the inner upper layer of the filtration tank 20 to the raw water contained in the filtration tank 20 using the aeration means 24 is further included.

The purification of raw water into household water and drinking water using the household water purification device and the water purification method of the present embodiment as described above is as follows.

First, the first valve V1 provided in the raw water supply pipe 11 is opened to supply raw water to the filtration tank 20.

At this time, the ozone generated from the ozone generator 12 is opened to the raw water flowing into the filtration tank 20, and the ozone is injected through the ejector 13 by opening the check valve CV.

As described above, the raw water injected with ozone is introduced into the filtration tank 20 through the level switch valve SV. At this time, if the desired amount is received in the filtration tank 20, the raw water is blocked by the level switch valve SV. As a result, no supply of raw water is made and a constant amount of raw water is always accommodated inside the filtration tank.

In this way, when the supply of raw water is blocked, the check valve CV is closed to stop the injection of ozone to prevent a large amount of ozone from being injected into the raw water.

As described above, the raw water flowing into the filtration tank 20 is first filtered by the filtration filter F, and various biological contaminants contained in the raw water are oxidized and removed by ozone.

As described above, the ultraviolet lamp 23 is operated while filtration of the raw water by ozone is performed inside the filtration tank 20 to irradiate the raw water and the inner wall of the filtration tank 20.

When the ultraviolet ray is irradiated to the inner wall of the filtration tank 20 using the ultraviolet lamp 23 as described above, the photocatalyst 21 such as titanium oxide coated on the inner wall of the filtration tank 20 is activated to activate the metal oxide contained in the raw water. The same metal contaminants are removed.

Filtration of such raw water is carried out in the filtration tank 20 and continues along the partition space partitioned by the partition wall 22.

At this time, ozone is vaporized and collected in the upper portion of the inside of the filtration tank 20, and the remaining ozone is aerated into raw water by the aeration means 24 and reused.

When the filtration of the raw water is made as described above is used as domestic water such as washing dishes through the living water supply pipe 31 that is opened and closed by the second valve (V2) or flows into the water filter 30 through the third valve (V3). It is purified and used as drinking water that the human body drinks through the drinking water supply pipe 32.

Drinking water discharged through the drinking water supply pipe 32 in the above is used because ozone in the range below the allowable ozone concentration (0.01ppm / h or less) is used, so it is not harmful to the human body, but rather various impurities or bacteria parasitic inside the human body It is effective for improving human health by removing harmful microorganisms and removing minerals and toxic substances.

The water purification device and water purification method of domestic water of the present invention made by the present invention is purified by injecting a small amount of ozone as well as biological contaminants contained in the raw water as well as harmful metal contaminants by using photocatalyst and ozone to supply raw water to the home. It is economical because it can improve the quality of the purified water and supply not only drinking water but also purified household water without separate water treatment device.
