１４１１４２号公報）。[Prior art and problems to be solved by the invention] Conventionally,
A method of using hydrogen peroxide is known as a method for exterminating red tide in seawater and blue-green algae in freshwater (Japanese Unexamined Patent Publication No. 1983-1999).
141142).

た。However, in this method, when hydrogen peroxide is added to water, it immediately reacts with plankton and floating iM dust in the water, especially metal oxides, and generates active oxygen, which exerts a plankton extermination effect. The problem is that the effect is near the water surface and the duration of the effect is short.
また、前記公知例には過酸化水素を担持体に担持させた
状態で水中に投入する方法が記載されているが、具体的
にいかなる担持体が使用されるか開示されていない。Furthermore, although the above-mentioned known example describes a method in which hydrogen peroxide is introduced into water in a state in which it is carried on a carrier, it does not specifically disclose what kind of carrier is used.
そこで、本発明者等は活性酸素の放出持続時間が長い水

特徴する請求項２の発明）。Similarly, in order to achieve the above-mentioned object, the present invention includes means for bringing hydrogen peroxide supported on porous calcium silicate powder into contact with water contaminated with phytoplankton or the like. ).
［作用］
本発明においては過酸化水素の担持体として多孔質珪酸
カルシウム粉粒体を採用しているので、過酸化水素が前
記粉粒体の空隙に吸収される。[Function] In the present invention, porous calcium silicate powder is used as a carrier for hydrogen peroxide, so hydrogen peroxide is absorbed into the voids of the powder.

に水が接触してその粉粒体からカルシウムイオンが溶出
してくる。そして、このカルシウムイオンと過酸化水素
とが反応して活性酸素を発生する。When the granular material that has absorbed hydrogen peroxide is poured into water contaminated by red tide or the like, the water comes into contact with the pores of the porous calcium silicate, and calcium ions are eluted from the granular material. Then, this calcium ion and hydrogen peroxide react to generate active oxygen.
この過程において前記カルシウムイオンの溶出が徐々に
進むので、活性酸素の発生が水中においても持続する。During this process, the elution of the calcium ions proceeds gradually, so that the generation of active oxygen continues even in water.
その結果、活性酸素によるプランクトン等の駆除が持続
することになる。As a result, the extermination of plankton and the like by active oxygen continues.

０．５１）Ｐｍに減少していた。The entire amount of this hydrogen peroxide carrier was poured into 100 liters of fresh water where algal blooms were occurring. Then, the generation status of active oxygen and the color tone of blue-green algae were observed. As a result, water came into contact with the voids in the porous calcium silicate and calcium ions were eluted, and the calcium ions and hydrogen peroxide reacted, generating active oxygen and changing the color tone of the blue-green algae over a period of approximately 2 hours. During this time, the support repeatedly floated and sank in the water, and active oxygen continued to be generated. As a result, the algal blooms were completely exterminated by active oxygen, and after 6 hours, they had settled to the bottom of the container together with the carrier. When phytoplankton in the water was observed under a microscope, no living plankton was observed. Furthermore, when the phosphorus content in the water was quantified before and after the experiment, it was found to have decreased from 5 ppm to 0.51) Pm.

少ないだけでなく発生継続時間も１０分と短かった。[Comparative Example 1] Instead of porous calcium silicate hydrate, concrete powder obtained without steam curing was used as a carrier, and when hydrogen peroxide was added to this, the two reacted violently immediately after the addition. At this point, a considerable amount of active oxygen was released. Using this carrier, an experiment was conducted in the same manner as in the previous example. As a result, the carrier immediately settled to the bottom of the fresh water container after coming into contact with the fresh water, and not only little active oxygen was generated, but the generation duration was as short as 10 minutes.
