The present invention relates to an apparatus for purifying the quality of drinking water such as tap water and well water to make it of good quality. Activated carbon and cation exchange resins have conventionally been used to improve the quality of drinking water such as tap water and well water. The former type of activated carbon is effective in removing organic matter and scale, but it is difficult to recycle at home, so it has the disadvantage of being used for a long time without being regenerated, causing rot.
Although the latter cation exchange resin has the function of softening hard water, it also has the drawback of removing useful mineral ions. As a water reforming device, a descaling device using calcium sulfite is disclosed in JP-A-51-135169. Further, an apparatus for removing organic matter or descaling using an anion exchange resin or activated carbon is disclosed in Japanese Utility Model Application Publication No. 159793/1983. Further, Japanese Patent Laid-Open No. 52-20657 discloses a water treatment device that can switch between producing pure water using activated carbon and an ion exchange resin or producing mineral water using activated carbon and calcium carbonate. However, both devices only descaling,
Or, it only has the functions of descaling, producing minerals, producing pure water, and removing organic matter, and simultaneously achieves descaling and organic matter removal while containing necessary calcium, ions, and other mineral components. It was not possible to make good drinking water. The present invention not only eliminates such drawbacks and removes scale and organic matter, but also increases the concentration of useful calcium and retains other useful mineral ions such as magnesium and zinc. Moreover, calcium sulfite has excellent descaling power. It is an object of the present invention to provide an excellent water purification device that can suppress the release of sulfite ions, which are harmful if used in too large a quantity, and can obtain safe and high-quality alkaline drinking water. This idea is to provide a descaling layer 3 containing granular calcium sulfite as a main component on the upstream side of an enlarged chamber 2 provided in a water passage 1, and then a descaling layer 3 containing granular calcium sulfite as a main component on the downstream side. Providing an organic matter removal layer 4,
Furthermore, the present invention relates to a water purification device in which a calcium generation layer 5 is formed by being mixed with the descaling layer 3 or the organic matter removal layer 4, or by filling an intermediate space inside the enlarged chamber 2 with limestone pieces. Examples will be described below based on the drawings. The embodiment shown in FIG. 1 includes a descaling layer 3 in which the internal space of the expanded chamber 2 is filled with 200 g of calcium sulfite,
A calcium generation layer 5 filled with 1500 g of limestone chips having a diameter of about 1 to 5 m/m and an organic matter removal layer 4 filled with 400 g of a macroporous weakly basic anion exchange resin were formed in sequence. In this embodiment, the tap water sent from the water passage 1 to the enlarged room 2 is first decalcified by the calcium sulfite in the descaling layer 3 to an almost undetectable extent. Next, the decalcified water has an increased calcium concentration due to calcium leached from the limestone chips of the next calcium-generating layer 5. Furthermore, the organic matter contained in the water is removed by the macroporous weakly basic anion exchange resin of the next organic matter removal layer 4.
It removes COD to 0.5ppm or less and at the same time becomes alkaline with a pH of 7.5 or higher. In addition, the macroporous weakly basic anion exchange resin, which is an anion exchange resin, captures the sulfite ions generated from calcium sulfite in the descaling layer 3 on the upstream side and prevents them from flowing out. This prevents contamination. An anion exchange resin whose performance has deteriorated due to adsorption of a large amount of organic matter can be easily regenerated by passing a sodium carbonate solution through it. An example of the test results of this example is shown in the table below.

スが極めて軽徴で済む。[Table] As can be seen from the test results, the water quality is slightly alkaline, COD has decreased to about 0.2 ppm, calcium concentration is over 60 ppm, which is considered desirable for health, and limescale has become undetectable. There is. It should be noted that another mineral ion generation layer may be provided in the enlarged chamber 2 that generates other mineral ions that are beneficial for health (for example, Mg ++ , Zn ++ , K + ).
In the embodiment shown in Fig. 2, limestone chips are removed from the descaling layer 3.
This is an example in which calcium-generating layers 5 made of only limestone fragments are provided in three separate locations. The operation and effect are the same as in the previous embodiment. As described above, according to the present invention, descaling and removal of organic matter can be sufficiently performed, and the water quality can be made alkaline and rich in calcium, which is useful for health.
Furthermore, there is an effect that excellent drinking water can be obtained by retaining the potassium, magnesium, and zinc ions that are originally contained in tap water and well water. In addition, the anion exchange resin for removing organic matter can be easily recycled at home, so it has the advantage that it can always be used in a fresh state. Moreover, even if calcium sulfite, which has superior descaling power compared to activated carbon, is used, the sulfite ions generated from it, which can be harmful to health if too much is produced, are removed by the organic matter removal layer, which is mainly composed of anion exchange resin, located downstream. 4, it is prevented from flowing out and mixing with drinking water, and is safe while maintaining strong descaling power. Furthermore, like activated carbon, calcium sulfite does not become a breeding ground for bacteria when used for a long period of time, and can be used for a long period of time without being replaced, requiring very little maintenance.
