The present invention relates to a water purifying agent for removing harmful ions.

Conventionally, various materials have been used to purify tap water, but among them, hollow fiber ( ) A water purifier composed of a membrane and granular activated carbon or a combination of a hollow fiber membrane and a zeolite is recognized as effective. This water purifying agent is mainly intended to remove particles larger than the pore diameter of free chlorine and hollow fiber membranes, and is not intended to remove harmful ions, and no harmful ions are removed.

In addition, there are methods of using anion and cation ion exchange resins to remove harmful ions. However, ion exchange resins are expensive and difficult to operate or regenerate.

On the other hand, protein fibers (e.g., wool) are themselves known as ion exchange resins of various cations and anions, and in particular, have some ability to adsorb heavy metals, but their adsorption capacity and adsorption rate are not practically satisfactory.

Thus, the inventors pay attention to the ion-exchange resin properties of protein fibers, and solve the problem that they are effective in removing harmful ions from the size of their surface area, but are reactively weak and cannot be practically used. And to provide a harmful ion removal water purification agent to effectively remove impurities.

In order to solve the above problems, one of the harmful ion removing water purification agents of the present invention is a multiple polymerization of a composite layer composed of two layers of wool and activated carbon and a composite layer composed of two layers of wool and sponge from the water passage side. It is characterized by being configured.

Another of the harmful ion removing water purifying agents of the present invention is characterized in that a composite layer composed of two layers of sponges, wool, and two layers of activated carbon from the water supply side is alternately polymerized. .

The harmful ion removal water purifier of the present invention configured as described above is disposed and fixed in the flow path of the water to be treated, and when the treated water is permeated, the harmful ions and impurities in the water are temporarily adsorbed to the activated carbon as the absorbent and adsorbent. Animal protein fibers such as beaches have the same properties because of their large surface area, but they are absorbed and absorbed into animal protein fibers such as wool and beach while the water flow is stopped by intermittently operating the treated water using ion exchange resin properties. In addition to treating most of the harmful ions and impurities adsorbed, it also processes the harmful ions absorbed and adsorbed by activated carbon due to the body structure, and the elution of impurities into the water. After the treatment of harmful ions and impurities, it is activated again.

Hazardous ions and impurities absorbed and adsorbed on activated carbon have a longer idle time, and more ions and impurities are released into the water due to temperature changes, pressure changes, and fluctuations, and they are converted into animal protein fibers such as wool and sponges. Is processed. That is, reactivation of activated carbon is performed. In addition, activated carbon plays a role as a buffer reservoir against the increase in the flow rate of intermittent operation, the increase of harmful ions and impurities. And since this chemical reactive treatment is performed in a number of stages, the processing capacity is extremely high. In particular, the treatment of fluoride in hot water is chemically treated using ion exchange resin properties, so the higher the temperature, the higher the treatment capacity.

Referring to the drawings, one embodiment of the harmful ion removing water purifying agent of the present invention is a composite layer composed of two layers of wool (1) and activated carbon (2) in the water passage shaft (lower side) as shown in FIG. (3) and the composite layer 5 which consists of two layers of the wool 1 and the sponge 4 are alternately many, and in this example, it consists of 8-stage superposition | polymerization.

The harmful ion removing water purifier 6 of the embodiment configured as described above is placed in the water purification container 8 by placing a filter 7 such as a nonwoven fabric up and down. Then, the treated water is passed through from below and used.

The specific test example will be described. Hazardous ion removal water purification agent having the structure shown in FIG. 1 at a blending ratio of 10 g of wool, 5 g of sea sponge, and 30 g of activated carbon in a water purification container 8 having an inner diameter of 50 mm, a height of 200 mm, and a capacity of 200 ml ( As shown in Fig. 2, the filter 7 of the nonwoven fabric is placed and set up and down, and the tap water having a residual chlorine concentration of 0.7 ppm is flowed at about 2 at the bottom. When water was passed for 2 minutes at / min and intermittent operation for 4 minutes was performed, the results as shown in Table 1 below were obtained.

TABLE 1

On the other hand, when explaining the comparative example, a non-woven fabric filter with a deionized ion removing water purifier formed of six layers of 15 g of wool and 5 g of sea sponge in the order of wool, sponge, wool, and sponge in the same water purification container as the above test example. And set it, and tap water with a residual chlorine concentration of 0.7 ppm from the lower part 2 When water was passed for 2 minutes at / min and intermittent operation for 4 minutes was performed, the results as shown in Table 2 below were obtained.

TABLE 2

As apparent from Table 1 and Table 2, the noxious ion removing water purification agent of the test example was found to be more water-treated than the noxious ion removing water purification agent of the comparative example, and the residual chlorine removal rate was high.

Next, the filter 7 of the nonwoven fabric is disposed above and below the harmful ion removing water purifying agent 6 as in the test example, set in the purified water container 8, and the amount of the test water for adding tap water and metal ions from the lower side is 200 ml of water each. 50 per / minute After passing through, analysis of the removed state of metal ions and the like was carried out to obtain results as shown in Table 3 below. In addition, analysis was performed according to JISK-0101.

TABLE 3

As is apparent from Table 3 above, according to the harmful ion removing water purifying agent of the present invention, metal ions can be treated, and in particular, hexavalent chromium and cadmium have a high removal rate and can be effectively removed.

In addition, as shown in FIG. 3, another harmful ion removing water purifying agent of the present invention is the composite layer 9 and the sponge 4, which are made of two layers of sea surface 4, wool 1, on the water passing side. The composite layer 10 composed of two layers of activated carbon 2 is alternately polymerized, but the harmful ion removing purifier 11 substantially changes its effect with the harmful ion removing purifying agent 6 of the above embodiment. There is no order, just the order of stratification.

In addition, when the harmful ion removal water purifying agent of the present invention is used in combination with the antibacterial chitosan fiber and silver impregnated activated carbon on the water passage side, bacteria removal is also effectively performed in the initial stage of water passage, and the hollow fiber membrane for filtration, flat membrane and ceramic When a combination of a filter plate, a metal sintered filter plate, a follicle, a polyvinyl alcohol sponge, and the like is used, red rust, oxide particles, and the like are effectively removed in the initial stage of water passage. In addition, by using a combination of mineral-supplemented ganban stone, far-ceramics, zeolite, coral sand, marble and the like on the drainage side, the treated water can be flavored at the final stage of water flow.

As described above, the harmful ion removing water purifying agent of the present invention is intermittently operated for water passing and resting, whereby impurities are chemically treated and removed by wool and sponge during the resting time. In particular, since impurity treatment in hot water is also performed chemically, the higher the temperature, the higher the treatment capacity. In addition, due to the synergistic effect of wool, sponge and activated carbon with activated carbon, the metal can be temperature treated, and in particular, hexavalent chromium and cadmium, which are harmful to the human body, can be effectively removed. Therefore, when used for purification of drinking water at home, the consumption of drinking water per day is only 10 About 2 / Min for 5 minutes of use time, the remaining 23 hours and 55 minutes is a holding time, and impurities and harmful ions absorbed and adsorbed on activated carbon are taken out of wool and sponge during approximately 100% treatment. This is extremely useful. In addition, by adopting a multi-column type conversion treatment method, each tower is given a sufficient down time, which can be used as a continuous water purifier, for the purpose of purifying hot water in which harmful chlorine that damages hair and skin remains. It can be provided for practical use as water purifier for morning beauty shower, water purifier for bathroom hot water supply, water purifier for beauty salon, haircut shop, hospital, water purifier for business use for health conservation, water purifier for food and medicine, etc. have.
