Abstract
Description
本発明は、河川、汚濁水等の各種原水を清澄化する水の処理方法に関する。 The present invention relates to a water treatment method for clarifying various raw waters such as rivers and polluted water.
従来、水道水を調整するために河川等から取水した水を種々の方法で処理していた。例えば原水汚濁によっては、活性炭を加えた後、凝集沈殿、ろ過後の、処理水の還元電位を＋４００ｍＶ以下にすることや残留アルミ濃度を０．０５ｍｇ／ｌ以下にすることが困難であった。 Conventionally, water taken from rivers and the like has been treated by various methods in order to adjust tap water. For example, depending on the raw water pollution, it was difficult to reduce the treated water reduction potential to +400 mV or less and the residual aluminum concentration to 0.05 mg / l or less after adding activated carbon, coagulating sedimentation, and filtering.
そこで本発明者は、さらに水質の向上を計る方法について種々検討を加えた結果本発明を完成するに至った。 Therefore, the present inventor made various studies on methods for further improving the water quality, and as a result, the present invention was completed.
すなわち、本発明は、各種原水を電気石により接触・ろ過させ清澄化することを特徴とする水の処理方法である。 That is, the present invention is a water treatment method characterized in that various raw waters are clarified by contact and filtration with tourmaline.
本発明方法によって処理した水は、酸化還元電位を＋３５０ｍＶ以下に低減することができる。 Water treated by the method of the present invention can reduce the redox potential to +350 mV or less.
また本発明方法で処理することによって、従来除去が困難な残留アルミ濃度を０．０５ｍｇ／ｌ以下に低減することができる。 Further, the treatment with the method of the present invention can reduce the residual aluminum concentration, which has been difficult to remove in the past, to 0.05 mg / l or less.
なお、本発明方法によって処理した水は、酸化還元電位が＋３５０ｍＶ以下に低減することで、水粒子が細かく、水素イオン濃度が高いため物質との親和性が良く、そのため混和性に優れる。
現状の飲料水は酸化還元電位が＋４００ｍＶ以上で、酸化還元電位が高く、酸化力が大きい。この酸化還元電位を下げる事は、集団水分子結合を切ることにより、粘性が下がり、浸透力が高まり、溶解性や製造性を高め、高粘性物の溶解性を速めると同時に、酸化しにくく安定し新鮮度を保つことが出来る。In addition, the water treated by the method of the present invention has a good affinity with a substance because the water particles are fine and the hydrogen ion concentration is high by reducing the oxidation-reduction potential to +350 mV or less, and therefore, the miscibility is excellent.
The current drinking water has a redox potential of +400 mV or higher, a high redox potential, and a high oxidizing power. This reduction in oxidation-reduction potential is achieved by cutting the collective water molecule bond, thereby reducing viscosity, increasing osmotic power, improving solubility and manufacturability, speeding up the solubility of high-viscosity materials, and at the same time making it difficult to oxidize and stabilize. The freshness can be kept.
例えば、製造工程で使用される難溶解性、或いは粘性の高い粉末、例えばＣＭＣ（カルボキシメチルセルロースナトリウム）、キサンタンガム等は浸潤性が高く溶解する際に、ママコになり易い。本発明方法によって処理した酸化還元電位の低い水は、細粒化された水分子となり、個体内の溶出性を高め、浸透性・親和性に優れ、難溶解性・粘性の高い粉末粒子状物質或いは高分子化学製品等を短時間に溶解しやすくする。 For example, poorly soluble or highly viscous powders used in the production process, such as CMC (carboxymethylcellulose sodium), xanthan gum, etc., are highly invasive and tend to be masticated. Water with a low oxidation-reduction potential treated by the method of the present invention becomes a finely divided water molecule, improves the dissolution within the individual, has excellent permeability and affinity, and is a powdered particulate material with high solubility and high viscosity Alternatively, polymer chemical products and the like are easily dissolved in a short time.
難溶解性のＣＭＣは弾力性や形状保持に富み、つなぎ的に多くの食品・飼料・餌・化粧品等に使用されている。本発明方法によって処理した水を使用することで、難溶解性であるＣＭＣの保水性・浸透性を高め、溶解しやすくする。 Slightly soluble CMC is rich in elasticity and shape retention, and is used in many foods, feeds, baits, cosmetics and the like. By using the water treated by the method of the present invention, the water retention and permeability of CMC, which is hardly soluble, is increased and is easily dissolved.
本発明方法によって処理した水を使用することで、製麺等の食品製造に用いれば、短時間製造・味付け等が可能になる。 By using the water treated by the method of the present invention, if it is used for producing foods such as noodles, it can be manufactured and seasoned for a short time.
本発明方法によって処理した水道水を製造工程で使用することで、工業的にも前述溶解・湿潤性が高まり、安定した製品作りが可能になる。 By using the tap water treated by the method of the present invention in the production process, the above-mentioned dissolution and wettability is increased industrially, and a stable product can be made.
本発明方法によって処理した水道水の酸化還元電位を下げる技術は、新技術で、水道水の鮮度を保持・持続することを実現したものである。 The technology for lowering the redox potential of tap water treated by the method of the present invention is a new technology that realizes maintaining and maintaining the freshness of tap water.
本発明方法によって処理した水道水は、化粧品として使用でき、保水性・浸透性が高いので皮膚に塗布すると効果的である。 The tap water treated by the method of the present invention can be used as a cosmetic product and is effective when applied to the skin because of its high water retention and permeability.
本発明方法によって浄水場の取水原近傍や直接河川等や、クーリングタワー等で接触・ろ過使用すると殺菌・抗菌効果と酸化還元電位を＋３５０ｍＶ以下
にする事ができる。If the method of the present invention is used for contact and filtration in the vicinity of a water intake at a water purification plant, directly in a river, or a cooling tower, the bactericidal / antibacterial effect and the oxidation-reduction potential can be reduced to +350 mV or less.
本発明における各種処理水としてはダム、河川、湖沼、汚濁水、製造用水、工業用水道、上水道、下水道、廃水処理水等が挙げられる。これらの各種処理は、電気石によって接触・ろ過処理される。 Examples of the various treated waters in the present invention include dams, rivers, lakes, polluted water, production water, industrial water, waterworks, sewers, wastewater treated water, and the like. These various treatments are contacted and filtered with tourmaline.
本発明方法に用いられる電気石は多面体極性結晶体構造を有する天然鉱石で、半永久電極持っているおり、抗菌・脱臭効果を有する。特に鉄分の含有量が多いトルマリン（ショールトルマリン）、マグネシウムの含有量が多いドラバイトが好適に使用できる。このドラバイトの代表的な成分組成を示せばＳｉＯ２３２．７％、Ｂ２Ｏ３９．３４％、Ａｌ２Ｏ３２３．３４％、Ｆｅ２Ｏ３３．８１％、ＭｇＯ２２．６４％、ＣａＯ２．３０％、Ｎａ２Ｏ０．３５％、Ｌｉ２Ｏ０．２０％、Ｐ２Ｏ５０．０５％、Ｆ０．０６％から構成されている。
またこのドラバイトを用いてチップを調整する方法としてはドラバイト粉末（約２μ）にカオリン等を混合して例えばラッシリング型等の所望の形状に成形した後例えば１２５０℃の熱により蒸し焼き（還元焼成）することによって得ることができる。The tourmaline used in the method of the present invention is a natural ore having a polyhedral polar crystal structure, has a semi-permanent electrode, and has an antibacterial and deodorizing effect. In particular, tourmaline having a high iron content (shoal tourmaline) and drabite having a high magnesium content can be preferably used. Representative composition of this drabite is SiO 2 32.7%, B 2 O 3 9.34%, Al 2 O 3 23.34%, Fe 2 O 3 3.81%, MgO 22.64%, CaO2.30%, Na 2 O0.35%, Li 2 O0.20%, P 2 O 5 0.05%, and a F0.06%.
In addition, as a method of adjusting the chip using this drabite, kaolin or the like is mixed with drabite powder (about 2 μm) and formed into a desired shape such as a lashing type, and then steamed by heat at 1250 ° C. (reduction firing). Can be obtained.
次に本発明方法を上水道調達の場合を例にとり説明する。現在河川から上水道とするためには、一般的に取水口より取水した水を取水庭に取り入れ、これを沈砂池に導入し、原水ポンプ所を経て着水井から、急速・緩速攪拌槽で無機凝集剤を注入してフロック形成させ、沈殿池で固・液沈降分離を行う、沈殿物は排泥調整池に移送し、上澄水は、中塩素混和池で塩素、アルカリを注入して処理し、次いで、ろ過池でろ過した後、後塩素混和池において再度塩素、アリカリを注入して処理後、浄水池に送り、上水道として供給される。活性炭やオゾンを使用される場合もある。 Next, the method of the present invention will be described taking the case of water supply procurement as an example. In order to use the river as a water supply, the water taken from the intake is generally taken into the water garden and introduced into the sand basin. The flocculant is injected to form a floc, and solid / liquid sedimentation separation is performed in the sedimentation basin. Then, after filtering in a filtration pond, chlorine and ants are injected again in the post-chlorine mixing basin, treated, sent to a water purification pond, and supplied as water supply. Activated carbon or ozone may be used.
本発明方法は、例えばチップ状等に形成された電気石をネット状の袋に充填したものを、上記した取水口近傍、取水庭、沈砂池、中塩素混和池、ろ過池、後塩素混和池、浄水池など等に接触・ろ過させる処理を行う。 The method of the present invention comprises, for example, an electric stone formed in a chip shape or the like filled in a net-like bag, in the vicinity of the intake port, intake garden, sand basin, medium chlorine mixing pond, filtration pond, post chlorine mixing pond , Make contact with the water purification pond etc.
本発明方法を上水道の取水庭に、チップ状等に形成された電気石をネット状の袋に充填したものをけることによって、原水は電気石に接触・ろ過することで、活性水素、水粒子結合が細分化され、酸化還元電位の低い水となって凝集されやすい状態になる。 The raw water is brought into contact with the tourmaline and filtered by removing the net-shaped bag filled with tourmaline in the water intake garden of the method of the present invention. The bonds are subdivided and become water having a low oxidation-reduction potential, and are easily aggregated.
本発明方法は、他の方法として、電気石に焼成カキ殻、木炭、ゼオライト・チラン粒子状物等を単独または複数を組合せ、処理剤として併用することもできる。 In the method of the present invention, as another method, calcined oyster shells, charcoal, zeolite / tyran particulates or the like can be used alone or in combination as a treating agent.
本発明方法は、処理剤を籠、網状物、筒状カラム、格子状物等の容器に入れ、接触・ろ過させることも出来る。 In the method of the present invention, the treatment agent can be placed in a container such as a basket, a net-like material, a cylindrical column, a lattice-like material, and contacted and filtered.
本発明方法は、電気石を入れた水に電極を入れ、定電圧をかけることで、電解度を上げ、細菌を消滅させることが出来る。 In the method of the present invention, an electrode is placed in water containing tourmaline and a constant voltage is applied, whereby the degree of electrolysis can be increased and bacteria can be eliminated.
次に本発明方法を実施例で説明する。 Next, the method of the present invention will be described in Examples.
