本発明は浄水用脱残留塩素剤に関するもので、さらに詳
細に説明μれば市水の脱残留塩素剤として亜硫酸カルシ
ウム（Ｃａ Ｓ ０３ ）と水に難溶性の炭酸塩とを用
いて粒状の脱残留塩素剤を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a residual chlorine removal agent for water purification, and will be explained in more detail. The present invention provides a granular residual chlorine removal agent using the following methods.
近年市水中の残留塩素あるいは不快臭、不快味を除去し
、良質な飲料水を得るために活性炭等の吸着剤を特殊な
容器に収容して、これに塩素処理水を通して脱残留塩素
および各種夾雑物を除去する家庭用浄水器が販売されて
いる。In recent years, in order to remove residual chlorine, unpleasant odors, and unpleasant tastes in city water and obtain high-quality drinking water, adsorbents such as activated carbon are placed in special containers, and chlorinated water is passed through this to remove residual chlorine and various contaminants. There are household water purifiers on the market that remove waste.
特に脱残留塩素剤として市販浄水器には大部分活性炭が
使用され、一部亜硫酸カルシウムも検討されている。In particular, activated carbon is mostly used in commercially available water purifiers as a residual chlorine removal agent, and calcium sulfite is also being considered in some cases.
このように脱残留塩素剤として活性炭が使用される理由
として、脱残留塩素および脱不快味、脱不快臭および市
水中に含まれている各種夾雑物除去などにすぐれた効果
を有することは、良く知られている。The reason why activated carbon is used as a residual chlorine removal agent is that it has excellent effects in removing residual chlorine, unpleasant tastes, unpleasant odors, and various impurities contained in city water. Are known.
しかし、現在活性炭を使用した市販浄水器は、塩素処理
水を脱残留塩素しても（長期間脱残留塩素水を滞留した
場合）、脱残留塩素水中に一般細菌（雑菌）が増殖し、
飲料水水質基準（１００個／ １ ｃｃ以下）をオーバ
ーし飲料に不適な水となる場合がある。However, with current commercially available water purifiers that use activated carbon, even if residual chlorine is removed from chlorinated water (if residual chlorine water is retained for a long period of time), general bacteria (miscellaneous germs) will grow in the residual chlorine water.
Water may exceed drinking water quality standards (100 particles/1 cc or less) and become unsuitable for drinking.
これらの雑菌の増殖は、特に活性炭の表面あるいは細孔
に、市水中の一般細菌あるいは雑菌の栄養源となる各種
夾雑物が長期間使用において蓄積され、あたかも雑菌に
とって栄養源；となり、飲料水水質基準を満足すること
ができないこともあるのではない゛かと考える。The growth of these bacteria is caused by the accumulation of general bacteria in city water or various impurities that serve as a nutrient source for bacteria on the surface or pores of activated carbon over long periods of use, acting as a nutrient source for bacteria, resulting in poor drinking water quality. I think there may be times when it is not possible to meet the standards.
したがって前記雑菌の殺菌法として、最近、極微量で殺
菌効果のある貴金属イオンに着目し、特に銀イオンを利
用した殺菌製造を設けることが提案されているが、望む
ならばこのような特別な殺菌装置を使用しない方が好ま
しい。Therefore, as a method for sterilizing the aforementioned germs, it has recently been proposed to focus on precious metal ions, which have a sterilizing effect in extremely small amounts, and to provide sterilization production that uses silver ions in particular. It is preferable not to use the device.
ところで本発明者らは、従来、脱塩素剤として効果のあ
る亜硫酸カルシウムのみを粒状（造粒成型）にし、２５
０〜５００℃の熱処理をして用いていた。By the way, the present inventors have conventionally made only calcium sulfite, which is effective as a dechlorinator, into granules (granulation molding).
It was used after being heat treated at 0 to 500°C.
このように熱処理を行なわなければ、亜硫酸カルシウム
のみで粒状にしたものは、水中で崩壊し、すぐに元の粉
末になり、粒状物にする長所がなくなってしまうこと、
あるいはまた熱処理（２５０〜５００℃）を行なっても
、強度的に弱い、すなわち、長期間水中に浸漬すること
により、造粒粒子が崩壊し徐々に粉末化現象が起る。If heat treatment is not carried out in this way, granules made from calcium sulfite alone will disintegrate in water and quickly return to their original powder form, eliminating the advantage of making them into granules.
Alternatively, even if heat treatment (250 to 500° C.) is performed, the strength is weak, that is, by immersing it in water for a long period of time, the granulated particles will collapse and a powdering phenomenon will gradually occur.
（しかし高温処理はど粉末化現象は小）。(However, the powdering phenomenon is small after high temperature treatment).
このような欠点をなくするために、本発明者らは、ここ
に亜硫酸カルシウムと水に難溶性の炭酸塩との混合物を
粒状に成型してなる脱残留塩素剤を創案した。In order to eliminate such drawbacks, the present inventors have devised a residual chlorine removal agent made by molding a mixture of calcium sulfite and a carbonate that is sparingly soluble in water into granules.
この成型には必要な水を添加して造粒成型し、造粒成型
後、１００℃以下の温度で、粒状物の水分を除去するだ
けで、長期間水中に浸漬しても粉末化現象は起らず、強
度的に犬なる脱残留塩素剤を製造することができるので
ある。For this molding, the necessary water is added and granulation molded, and after granulation molding, the water content of the granules is simply removed at a temperature of 100°C or less, and there is no powdering phenomenon even if immersed in water for a long period of time. This makes it possible to produce a highly effective residual chlorine removal agent.
さらに熱処理することにより、さらに強度の犬なるもの
が出来る。Further heat treatment produces even stronger dogs.
また、脱残留塩素効果も、亜硫酸カルシウムのみと比較
しても、はとんど変らず、“すぐれた性能を有するもの
である。In addition, the residual chlorine removal effect is almost the same when compared to calcium sulfite alone, and it has "excellent performance."
水に難溶性の炭酸塩として、特に炭酸カルシウム、炭酸
マグネシウムが効″巣的で、一般に食品添加物として使
用されているものは、すべて可能であり、この２つの炭
酸塩は、室温程度の乾燥でも十分、すぐれた固化の効果
、性能を有する。Calcium carbonate and magnesium carbonate are particularly effective as carbonates that are poorly soluble in water, and all of them are commonly used as food additives.These two carbonates can be dried at room temperature. However, it has sufficient solidification effect and performance.
その他の水に難溶性の炭酸塩として、炭酸マンガン、炭
酸等も使用可能である。Other poorly water-soluble carbonates such as manganese carbonate and carbonic acid can also be used.
また、使用上、あるいはコスト、効果（強度）、性能（
脱残留塩素）等の総合的にすぐれたものとして、炭酸カ
ルシウムが最適である。Also, in terms of use, cost, effectiveness (strength), performance (
Calcium carbonate is optimal as it has comprehensive properties such as removal of residual chlorine.
しかし亜硫酸カルシウムと水に難溶性の炭酸塩との組成
比も重要で、
の範囲が良く、これらの中でつ、特に、■＝１０〜に２
の範囲が、使用上（コスト、強度、性能）からもつとも
最適値である。However, the composition ratio of calcium sulfite and carbonate, which is sparingly soluble in water, is also important.
The range of is the optimum value from the viewpoint of use (cost, strength, performance).
１：２０以下すなわち、ＣａＳＯ３が少なくなると、脱
塩素性能が低下し、粒状物の添加量を多くしなければな
らない。When the ratio is less than 1:20, that is, when the amount of CaSO3 decreases, the dechlorination performance decreases, and the amount of granular material added must be increased.
一方１：１以上すなわちＣａＳＯ３が多くすると、亜硫
酸カルシウムのみの場合と同様に、１００℃以上の熱処
理が必要となる。On the other hand, if the ratio is 1:1 or more, that is, if the CaSO3 content is increased, heat treatment at 100° C. or higher is required, as in the case of only calcium sulfite.
しかしながら、１：１以下（１：１０〜に１）の範囲で
はＣａＳＯ３のみの場合と脱残留塩素効果は、はとんど
変らない。However, in the range of 1:1 or less (1:10 to 1), the residual chlorine removal effect is almost the same as in the case of using only CaSO3.
