The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to purify tap water used as drinking water, ground water or seawater that has been desalinated and then natural. Another object of the present invention is to provide a method for purifying drinking water that can be changed to drinking water having the same physiological water quality as that of Iwashimizu and spring water.

[0003]

In order to achieve the above object, in the method for purifying drinking water of the present invention, water used as drinking water is purified by passing it through a purification stone layer having an adsorbing action for impurities and an elution action for minerals. It was configured to do.

[0004]

In the method for purifying drinking water of the present invention, as described above, tap water, ground water, etc. are not used as drinking water as they are, but they are used after passing through a layer of purified stone. Cadmium, cyanide, mercury, phthalate ester, PCB, which is harmful to the human body due to the adsorption of impurities
ABS, nitrous acid, BHC, lead, copper, bacteria, radioactivity, etc.
In addition, it removes pigments and odors, and mineralizes the purified stones to elute minerals, neutralizes PH in drinking water, and adjusts hardness appropriately, which is good for your health. You can get delicious drinking water. Further, in the method for purifying drinking water of the present invention, organic matter in drinking water can be decomposed, so it is possible to prevent water from spoiling in the rooftop tank and the like, and to suppress the growth of bacteria in water. Therefore, the freshness of water can be maintained for a long period of time.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is an explanatory view showing an example in which the method for purifying drinking water of this embodiment is applied to a water supply facility of a building. Tap water supplied from a water supply pipe 1 is first stored in an underground tank 2 and then Is pumped to the rooftop tank 4 by the pump 3, and tap water is purified by passing the water through the three water purifiers 5 in sequence. Then, this purified water is used in the kitchen, bathroom or toilet. In the figure, 6 is a ball tap.

In the water purifier 5, a plurality of purification stones having an impurity adsorbing action and a mineral elution action are provided. In this case, in the embodiment, as shown in FIG.
As the layers, the purified stone A layer, the purified stone B layer, and the purified stone C layer are sequentially arranged in the first to third layers, and the purified stone A is formed in the fourth to sixth layers in the same order as described above. Layer, Purified Stone B Layer, Purified Stone C
Layers, and the purified stone B layer is disposed in the lowermost layer on the outflow port 8 side to form a laminated structure of 7 layers of 3 types in total.

Here, the purified stone A layer and the purified stone B layer are composed of quartz diorite (the texture is a complete crystalline porphyry, the rock-forming mineral is mainly plagioclase, and the ablated quartz is mainly used. It is made of crushed stone, clinopyroxene, chlorite, apatite, and chlorite, and has a particle size of 3 mm to 10 mm. Has a positive mineral elution action, and the purified stone B has a physical and chemical adsorption action of harmful substances, pigments, odors and the like mainly contained in tap water. Incidentally, the physical adsorption action here is
Physically adsorbing harmful substances on the porous inner surface of purified stones.Chemical adsorption is the secondary action of the presence of harmful components by the elements or element compounds present on the porous inner surface of purified stones. It refers to chemical adsorption (due to the affinity between elements). The purified stone C is the purified stone A and the purified stone B.
Is melted at a predetermined ratio and cooled, then the particle size is 3 mm
It is crushed to about 10 mm and has an intermediate function of both purification stones A and B.

[Table 1]

Next, the operation of this embodiment will be described. The water pumped up from the underground tank 2 to the rooftop tank 4 is twice subjected to the elution action of the mineral content mainly by the ion exchange action by the purification stone A layer while passing through the running water channel of the purification device 5 and the purification stone. The layer B receives the adsorption action of harmful substances such as various bacteria and heavy metal ions, pigments, and odors three times.
Moreover, the purified stone C layer undergoes an average adsorption action and a mineral elution action twice, thereby improving the water quality and giving a good result to the organism seeking oxygen, and after receiving these actions alternately, the rooftop It will be sent to the tank 4. In this way, in the roof tank 4, harmful substances,
In addition, color and odor are removed, and water mineralized with minerals is stored. Therefore, drinking this water or using it for cooking can contribute to promotion of health.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to the above-mentioned embodiments, and design changes and the like within the scope not departing from the gist of the present invention. Even if it exists, it is included in the technical scope of the present invention. For example, although the three types of purified stone layers are arranged in seven layers in the embodiment, the present invention is not limited to this, and one type of purified stone layer may be arranged in one layer. The method of passing through the purification stone layer having an impurity adsorption action and a mineral elution action is all included in the present invention. In addition, although tap water is used as the drinking water for purification in the embodiment, ground water or water obtained by desalinating seawater may be used for purification, and the same effect can be obtained in this case.
