Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、溶存酸索量の高い水の製造方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for producing water with a high amount of dissolved acid.
（従来の技術）
水に酸素を溶かすことは、魚などの水中に住む生物を育
てるためだけでなく、植物を育てるためめ、また菌体を
用いた生産等においてもとても重要なことである。また
、活性汚泥などを用いて廃水処理をするときも′溶液中
の酸素濃度を高めておくことが重要である。(Prior Art) Dissolving oxygen in water is very important not only for growing organisms that live in water such as fish, but also for growing plants and in production using bacterial cells. Furthermore, when treating wastewater using activated sludge or the like, it is important to keep the oxygen concentration in the solution high.
従来、水に酸素を溶かす方法としては、空気を水にパブ
リングするなどの方法が行われている。Conventionally, methods such as bubbling air into water have been used to dissolve oxygen in water.
しかし、この様な方法では水に対する酸素の溶け込み効
率は非常に悪い。However, in such a method, the efficiency of dissolving oxygen into water is very low.
そのために、水に対して酸素を効率よく溶かし溶存酸索
量の高い水を作ることが、期待されている。To this end, it is expected to efficiently dissolve oxygen in water to create water with a high amount of dissolved acid.
（発明が解決しようとする課８）
本発明の目的は、簡単な処理により、溶存酸素量の高い
水を製造することにある。(Problem 8 to be Solved by the Invention) An object of the present invention is to produce water with a high amount of dissolved oxygen through simple treatment.

法に関する。(Means for Solving the Problems) The present invention relates to a method for producing water with a high amount of dissolved oxygen by allowing a hydrogen peroxide decomposition catalyst to act on a hydrogen peroxide-aqueous system.
本発明の原料となる過酸化水素水は、水に過酸化水素が
溶解しているものであれば何でも良く、その濃度は、水
に対する酸素の飽和濃度から計算して決めれば良い。例
えば、２０℃で反応を行うとすると、水に溶解する飽和
酸素濃度が、０．００４３４ｇ／１００ｇであるので、
過酸化水素が分解して生じた酸素がその濃度以上になる
ように過酸化水素濃度を調整する。The hydrogen peroxide solution serving as the raw material of the present invention may be any water as long as hydrogen peroxide is dissolved in water, and its concentration may be determined by calculating from the saturated concentration of oxygen with respect to water. For example, if the reaction is carried out at 20°C, the saturated oxygen concentration dissolved in water is 0.00434g/100g, so
The hydrogen peroxide concentration is adjusted so that the oxygen produced by hydrogen peroxide decomposition is at or above that concentration.
本発明において用いられる、過酸化水素分解触媒は、一

水素の濃度や使用する触媒の種類等により異なるが、例
えば、２０℃でイオン交換水１０００ｍｌに３０％過酸
化水素溶液を１ ｍｌ添加した系にカタラーゼを用いる
場合は約０．Ｏｌｇ−０．１ｇ，二酸化マンガンを用い
る場合は約５ｇ〜１０ｇを添加する。通常、反応は１０
分〜１５分程度で終了するが、金属触媒を用いた場合は
反応終了後に溶液をカラム等に通して触媒を除去する。As the hydrogen peroxide decomposition catalyst used in the present invention, a generally well-known metal catalyst such as manganese dioxide or an enzyme catalyst such as catalase that is uniformly soluble in water can be used. At this time, the reaction may be carried out using a catalyst immobilized on a carrier. The amount of catalyst used varies depending on the concentration of hydrogen peroxide and the type of catalyst used, but for example, when catalase is used in a system in which 1 ml of 30% hydrogen peroxide solution is added to 1000 ml of ion-exchanged water at 20°C, approximately 0. If using manganese dioxide, add about 5 g to 10 g. Usually the reaction is 10
The reaction takes about 15 minutes to complete, but if a metal catalyst is used, the catalyst is removed by passing the solution through a column or the like after the reaction is complete.
