Description
本発明は、藻類増殖促進用資材に関する。 The present invention relates to a material for promoting algae growth.
海域や淡水域等において、水中のケイ酸、カルシウム及び鉄が不足した場合、これらを栄養成分とする藻類（例えば、珪藻）が減少することで、赤潮が発生する場合がある。
また、赤潮が発生することによって、藻場と呼ばれる海草及び海藻等の繁茂する群落が衰退あるいは消失する「磯焼け」と呼ばれる現象が発生して、水棲生物の餌場や住処が減少し、水棲生物の成育環境が悪化するという問題があった。
When silicic acid, calcium and iron in water are deficient in sea areas and fresh water areas, red tide may occur due to a decrease in algae (for example, diatoms) containing these as nutrient components.
In addition, due to the occurrence of red tide, a phenomenon called "isoyake" occurs in which seagrass beds called seagrass beds and communities where seagrass grows decline or disappear, and the feeding grounds and habitats for aquatic organisms decrease, resulting in aquatic life. There was a problem that the growing environment of living things deteriorated.
この問題を解決するために、藻類の栄養成分であるケイ酸や鉄を供給して、海域や淡水域等の環境を保全あるいは改善する様々な技術が提案されている。
例えば、特許文献１には、石炭溶融灰または転炉スラグの少なくとも一方が詰め込まれたココナッツ繊維製の袋を海中に沈設しておくことを特徴とする磯焼け修復方法が記載されている。
また、特許文献２には、酸化珪素、酸化カルシウム、及び、酸化アルミニウムを含む塩基度が１．４以下のガラス化した高炉スラグ、酸化第一鉄、酸化カルシウム及び酸化珪素を含有する固体の粉と粒の混合物及び水酸化カルシウム粉からなる混合物に水を添加して、粒子間に水和物を生成させて凝集させた凝集体であることを特徴とする水域向けミネラル供給剤が記載されている。
さらに、特許文献３には、透水性を有する袋材に、二価鉄含有物質と腐植含有物質とが詰め込まれていることを特徴とする水域環境保全材料が記載されている。
In order to solve this problem, various technologies have been proposed to conserve or improve the environment such as sea areas and freshwater areas by supplying silicic acid and iron, which are nutritional components of algae.
For example, Patent Document 1 describes a method for repairing shore-burning, which comprises submerging a bag made of coconut fiber filled with at least one of molten coal ash or converter slag in the sea.
Further, Patent Document 2 describes a solid powder containing silicon oxide, calcium oxide, and vitrified blast furnace slag having a basicity of 1.4 or less, ferrous oxide, calcium oxide, and silicon oxide containing aluminum oxide. Described is a mineral feeder for water areas, which is an agglomerate in which water is added to a mixture of grains and a mixture of grains and calcium hydroxide powder to generate hydrate between the grains and aggregated. There is.
Further, Patent Document 3 describes a water-based environmental protection material characterized in that a divalent iron-containing substance and a humus-containing substance are packed in a water-permeable bag material.
転炉スラグや高炉スラグ等のスラグを用いて、海域や淡水域等に藻類の栄養成分であるケイ酸や鉄を供給する場合、スラグに含まれるフッ素、硫黄、アルミニウム等が溶出して、藻類や水棲生物の生育に悪影響を与えることがある。また、スラグに含まれるカルシウムにより、海域や淡水域等のｐＨが強アルカリ性（例えば、１２〜１３程度）となり、藻類や水棲生物の生育に悪影響を与えることがある。
また、海域や淡水域等の環境を保全あるいは改善するには、藻類の栄養成分であるケイ酸、カルシウム及び鉄を、長期に亘って安定的に供給することが望ましい。
本発明の目的は、藻類を増殖させるための水のｐＨが強アルカリ性（例えば、１０．０以上）になることを防ぎ、該水中にケイ酸、カルシウム及び鉄を安定的に供給でき、かつ、回収等が不要で、管理が容易な資材を提供することである。
When slag such as converter slag or blast furnace slag is used to supply silicic acid and iron, which are nutrient components of algae, to sea areas and freshwater areas, fluorine, sulfur, aluminum, etc. contained in the slag are eluted and the algae And may adversely affect the growth of aquatic organisms. In addition, calcium contained in slag makes the pH of sea areas and freshwater areas strongly alkaline (for example, about 12 to 13), which may adversely affect the growth of algae and aquatic organisms.
In addition, in order to conserve or improve the environment such as sea areas and freshwater areas, it is desirable to stably supply silicic acid, calcium and iron, which are nutritional components of algae, for a long period of time.

藻類増殖水としては、特に限定されるものではなく、淡水、汽水および海水のいずれでも良い。また、藻類増殖水とは、上述した淡水等の水を収容した養殖池若しくは養殖槽、または、自然界における海水域若しくは河川域等であって、上記藻類が存在している水をいう。該藻類は、自然に存在するものであっても、人為的に投入されたものであってもよい。
本発明の藻類増殖促進用資材は、好ましくは、藻類が減少した海水域若しくは河川域、または、藻類の少ない養殖池若しくは養殖槽に投入する。
By supplying the algae growth promoting material of the present invention into water for growing algae (algae growth water), the algae in the water can be grown.
The algae may be any algae whose growth is promoted by the algae growth promoting material of the present invention, and examples thereof include diatoms.
The algae growth water is not particularly limited, and may be fresh water, brackish water, or seawater. Further, the algae breeding water refers to aquaculture ponds or aquaculture tanks containing the above-mentioned freshwater or the like, or seawater areas or river areas in the natural world where the above-mentioned algae are present. The algae may be naturally occurring or artificially introduced.
The algae growth promoting material of the present invention is preferably put into a seawater area or river area where algae is reduced, or a aquaculture pond or aquaculture tank where algae is low.
藻類増殖促進用資材を、藻類増殖水の中に供給する方法としては、藻類増殖促進用資材を、そのまま水中に散布する方法や、藻類増殖促進用資材を収容することができ、かつ、通水性を有する収容手段に、藻類増殖促進用資材を収容した後、水中に沈める方法等が挙げられる。
本発明の粉粒状の形態の藻類増殖促進用資材を、そのまま水中に散布する場合、該資材を構成するケイ酸カルシウム含有材料、腐植物質、鉄化合物および酸化防止剤が水中で分離しないようにする観点から、水深の浅い場所に藻類増殖促進用資材を投入することが好ましい。また、該資材を養殖池や養殖槽に投入する場合において、養殖池等に水を入れる前に、あるいは、養殖池等に水を入れ始めた後であってまだ水深が浅いときに、藻類増殖促進用資材を投入することが好ましい。
As a method of supplying the algae growth promoting material into the algae growth promoting water, a method of spraying the algae growth promoting material as it is in water, a method of accommodating the algae growth promoting material, and water permeability can be used. Examples of the accommodating means having the above include a method of accommodating a material for promoting algae growth and then submerging it in water.
When the algae growth promoting material in the powdery granular form of the present invention is sprayed as it is in water, the calcium silicate-containing material, humus, iron compound and antioxidant constituting the material are prevented from separating in water. From the viewpoint, it is preferable to put the algae growth promoting material in a place where the water depth is shallow. In addition, when the material is put into a aquaculture pond or aquaculture tank, algae grow before the aquaculture pond or the like is filled with water, or after the water is started to be poured into the aquaculture pond or the like and the water depth is still shallow. It is preferable to add promotion materials.
ここで、通水性を有する収容手段とは、例えば、セルロース繊維、ポリアミド合成繊維、ビニロン繊維、ポリエステル繊維、ポリオレフィン繊維、レーヨン繊維、アラミド繊維、ポリプロピレン繊維、ポリエチレン繊維等の有機繊維や、ガラス繊維、セラミック繊維、シリカ繊維、アルミナ繊維、ロックウール、スラグウール等の無機繊維等の繊維を用いた、織布または不織布からなる袋；鉄、プラスチック、木材、石材、陶磁器、または、セメント等の水硬性組成物を原料として形成した、収納スペースを有する容器等が挙げられる。
収容手段における通水性を有する部分は、収容手段の一部分（一領域）でもよいし、全体（全領域）であってもよい。
Here, the storage means having water permeability includes, for example, organic fibers such as cellulose fibers, polyamide synthetic fibers, vinylon fibers, polyester fibers, polyolefin fibers, rayon fibers, aramid fibers, polypropylene fibers, polyethylene fibers, and glass fibers. A bag made of woven cloth or non-woven fabric using fibers such as ceramic fiber, silica fiber, alumina fiber, rock wool, slag wool and other inorganic fibers; water-hardness such as iron, plastic, wood, stone, ceramics, or cement. Examples thereof include a container having a storage space formed from the composition as a raw material.
The water-permeable portion of the accommodating means may be a part (one area) or the whole (entire area) of the accommodating means.
通水性を有する部分の目開きの寸法は、藻類増殖促進用資材の流出を防ぐ観点から、収容手段に収容された藻類増殖促進用資材が通過することができない寸法であることが好ましい。例えば、粒度が３０ｍｍである造粒物からなる藻類増殖促進用資材を収容する収容手段として、目開きの寸法が１０ｍｍであるネット状の袋を使用することができる。 From the viewpoint of preventing the outflow of the algae growth promoting material, the size of the opening of the water-permeable portion is preferably a size that the algae growth promoting material contained in the accommodating means cannot pass through. For example, a net-shaped bag having an opening size of 10 mm can be used as a storage means for accommodating a material for promoting algae growth, which is made of a granulated product having a particle size of 30 mm.
収容手段に収容した藻類増殖促進用資材を、藻類増殖水の中に供給した後、該資材は、ケイ酸、カルシウムおよび鉄が水中に供給されるに従って、徐々に小さくなる。該資材の粒度が、収容手段の通水性を有する部分の目開き寸法よりも小さくなった場合、該資材は、該部分から落下する。該資材が収容手段の中で無くなった場合、新しい資材を収容手段の中に供給すればよい。新しい資材を供給すべき時期は、収容手段の中の藻類増殖促進用資材の目視等によって判断できる。
なお、収容手段の内部または水底に、小さくなった藻類増殖促進用資材が残存していても、時間が経てば自然に消滅するので、除去する必要はない。
After supplying the algae growth promoting material contained in the storage means into the algae growth water, the material gradually becomes smaller as silicate, calcium and iron are supplied into the water. When the particle size of the material becomes smaller than the opening size of the water-permeable portion of the accommodating means, the material falls from the portion. If the material is exhausted in the containment means, new material may be supplied into the containment means. The time when new materials should be supplied can be determined by visually observing the materials for promoting algae growth in the containment means.
Even if the reduced algae growth promoting material remains inside the accommodating means or on the bottom of the water, it does not need to be removed because it disappears spontaneously over time.

[Comparative Example 2]
After obtaining a mixture in the same manner as in Example 1 except that an antioxidant was not used, the pH and the like of the mixture were measured.
The results are shown in Tables 2-5.
表２から、本発明の藻類増殖促進用資材を用いた場合（実施例１〜４）、３時間〜１４日経過時のｐＨは、３．７〜６．４の範囲内であり、強酸性（ｐＨが３．５未満）でも強アルカリ性（ｐＨが１０．０以上）でもないことがわかる。一方、ケイ酸カルシウム含有材料のみを用いた場合（比較例１）、１４日経過時におけるｐＨは、１０．０であり、強アルカリ性になっていることがわかる。
また、表３から、本発明の藻類増殖促進用資材を用いた場合（実施例１〜４）と、ケイ酸カルシウム含有材料のみを用いた場合（比較例１）及び酸化防止剤を含まない場合（比較例２）を比較すると、実施例１〜４では、１４日経過時におけるカルシウムの濃度は、４５．５〜７５．３ｍｇ／リットルであり、比較例１（１８．４ｍｇ／リットル）よりも多く、比較例２（４８．３ｍｇ／リットル）と同様以上であることがわかる。
また、１日経過以降であっても安定的にカルシウムの濃度が大きくなっていることから、長期に亘って安定的に、カルシウムを水中に供給できることがわかる。
From Table 2, when the algae growth promoting material of the present invention was used (Examples 1 to 4), the pH after 3 hours to 14 days was in the range of 3.7 to 6.4, and it was strongly acidic. It can be seen that it is neither (pH less than 3.5) nor strongly alkaline (pH is 10.0 or more). On the other hand, when only the calcium silicate-containing material was used (Comparative Example 1), the pH after 14 days was 10.0, indicating that the material was strongly alkaline.
Further, from Table 3, when the algae growth promoting material of the present invention was used (Examples 1 to 4), when only the calcium silicate-containing material was used (Comparative Example 1), and when the antioxidant was not included. Comparing (Comparative Example 2), in Examples 1 to 4, the calcium concentration after 14 days was 45.5 to 75.3 mg / liter, which was higher than that of Comparative Example 1 (18.4 mg / liter). It can be seen that the amount is similar to or higher than that of Comparative Example 2 (48.3 mg / liter).
In addition, since the calcium concentration is stably increased even after the lapse of one day, it can be seen that calcium can be stably supplied to water for a long period of time.
また、表４から、本発明の藻類増殖促進用資材を用いた場合（実施例１〜４）、１日経過以降であっても安定的にケイ素の濃度が大きくなっていることから、長期に亘って安定的に、ケイ酸を水中に供給できることがわかる。

また、表５から、本発明の藻類増殖促進用資材を用いた場合（実施例１〜４）と比較例２を比較すると、３時間経過時の鉄の濃度は同等であったが、７日経過以降の鉄濃度は、比較例２よりも、実施例１〜４における鉄の濃度の方が大きいことがわかる。
ケイ酸カルシウム含有材料のみを用いた比較例１では、鉄の濃度は０ｍｇ／リットルであった。
Further, from Table 4, when the algae growth promoting material of the present invention was used (Examples 1 to 4), the silicon concentration was stably increased even after 1 day, so that the silicon concentration was stably increased for a long period of time. It can be seen that silicic acid can be stably supplied to water throughout.
In particular, in Examples 1 and 3, the silicon concentrations after 14 days were 18.3 mg / liter (Example 1) and 17.2 mg / liter (Example 3), and Comparative Example 1 (6). It can be seen that the concentration of silicon in Comparative Example 2 (12.6 mg / liter) is higher than that in Comparative Example 2 (1.5 mg / liter).
Further, from Table 5, when the algae growth promoting material of the present invention was used (Examples 1 to 4) and Comparative Example 2 were compared, the iron concentration after 3 hours was the same, but 7 days. It can be seen that the iron concentration after the lapse of time is higher in the iron concentrations in Examples 1 to 4 than in Comparative Example 2.
In Comparative Example 1 using only the calcium silicate-containing material, the iron concentration was 0 mg / liter.
