Description
本発明は、水棲生物飼育用の水槽の底に敷くゼオライト製底砂に関する。 The present invention relates to zeolite bottom sand laid on the bottom of an aquarium for aquatic life breeding.
ゼオライトは骨格内に細孔を有する多孔体であり、高い吸着能力とイオン交換能力を示すことから、水を浄化する際の濾過剤として広く使用されている。また、水棲生物飼育用の水槽においては、ゼオライトを焼成する等して粒状体に加工して底砂として使用し、水を浄化して藻の繁殖の抑制効果が期待されている（特許文献１、非特許文献１参照）。 Zeolite is a porous body having pores in the skeleton, and exhibits high adsorption ability and ion exchange ability, and is therefore widely used as a filtering agent for purifying water. In addition, in an aquarium for breeding aquatic organisms, zeolite is calcined and processed into a granular material and used as bottom sand, and water is purified to suppress the growth of algae (Patent Document 1). Non-Patent Document 1).
ゼオライト製の底砂は工場で袋詰めに包装されて市場を流通する。ゼオライトは多孔体であるために脆いという特性があり、袋詰め作業時や輸送中に砂粒同士が擦れ合って表面が砕けて微粉末として脱落することは避けられない。そのため、新しい底砂を使用する際は包装袋から取り出して脱落した微粉末を洗い流してから水槽に入れる、というのが一般的な使用方法である。 Zeolite bottom sand is packed in bags at the factory and distributed in the market. Zeolite has a characteristic that it is brittle because it is a porous material, and it is inevitable that the sand particles rub against each other during bagging and during transportation, and the surface is crushed and falls off as a fine powder. For this reason, when using new bottom sand, it is a general usage method to wash out the fine powder that has been taken out from the packaging bag and dropped, and then put it into the water tank.
しかし、微粉末を完全に洗い流すことは難しく、微粉末が混じった底砂を水に投入することになる。微粉末が混じった底砂を水に投入すると微粉末が水中に浮遊して白濁する。しかも、ゼオライトは多孔体であり嵩比重が小さいので微粉末の沈降速度は極めて遅く、沈みきって白濁が解消されるまでに相当の時間がかかるという問題があった。 However, it is difficult to wash away the fine powder completely, and the bottom sand mixed with the fine powder is thrown into the water. When the bottom sand mixed with fine powder is poured into water, the fine powder floats in the water and becomes cloudy. In addition, since zeolite is a porous material and has a low bulk specific gravity, the sedimentation rate of the fine powder is extremely slow, and there is a problem that it takes a considerable amount of time until the cloudiness is eliminated.
ゼオライトを粒状体に加工する際に焼成温度を高くして焼き固めると微粉末の脱落を低減できるが、細孔構造が崩れて吸着能力やイオン交換能力が低下するので高温焼成は好ましくない。 If the calcination temperature is raised at the time of processing the zeolite into a granular material, the fine powder can be prevented from falling off, but the pore structure is destroyed and the adsorption capacity and ion exchange capacity are lowered, so high temperature calcination is not preferred.
なお、特許文献１に記載された底砂はゼオライト底砂はパウダー状の天然ゼオライトをポバールで固形化した層でコーティングされている。前記コーティング層はポバールをバインダーとしてゼオライト粉末が固形化されているので、ゼオライト微粉末は脱落しにくいと考えられるが、表面を有機バインダーを含む層でコーティングすることでゼオライトと水との接触面積が減少して浄化能力も低下すると考えられる。 The bottom sand described in Patent Document 1 is coated with a layer obtained by solidifying powdery natural zeolite with poval. Since the zeolite powder is solidified by using poval as a binder in the coating layer, it is considered that the zeolite fine powder is difficult to fall off, but the contact area between the zeolite and water can be increased by coating the surface with a layer containing an organic binder. It is thought that the purification capacity will decrease as well.
本発明は、上述した技術背景に鑑み、不可避的に発生するゼオライトの微粉末に対し、ゼオライトによる浄化能力を低下させることなく、短時間で白濁を解消できる水槽用底砂を提供することを目的とする。 The present invention has been made in view of the technical background described above, and an object thereof is to provide water tank bottom sand that can eliminate white turbidity in a short time without reducing the purification ability of zeolite with respect to inevitably generated fine zeolite powder. And
即ち、本発明は下記［１］〜［３］に記載の構成を有する。 That is, this invention has the structure as described in following [1]-[3].
［１］ゼオライト粒に凝集剤を配合してなることを特徴とする水槽用底砂。 [1] A bottom sand for an aquarium characterized by blending a flocculant with zeolite particles.
［２］前記ゼオライト粒１００質量部に対して凝集剤０．０１〜０．１質量部の割合で配合されている前項１に記載の水槽用底砂。 [2] The bottom sand for an aquarium according to item 1 above, blended in a proportion of 0.01 to 0.1 part by weight of a flocculant with respect to 100 parts by weight of the zeolite particles.
［３］前記凝集剤は鉱物由来の凝集剤である前１または２に記載の水槽用底砂。 [3] The bottom sand for an aquarium according to 1 or 2, wherein the flocculant is a mineral-derived flocculant.
上記［１］［２］に記載の水槽用底砂によれば、ゼオライト粒から脱落した微粉末が凝集剤によって速やかにフロックを形成し、短時間で沈降する。このため、ゼオライト微粉末による白濁を短時間で解消できる。 According to the bottom sand for aquariums described in [1] and [2] above, the fine powder dropped from the zeolite particles quickly forms flocs by the flocculant and settles in a short time. For this reason, white turbidity due to zeolite fine powder can be eliminated in a short time.
上記［３］に記載の水槽用底砂は鉱物系凝集剤を使用しているので、水棲生物に影響を及ぼさない。 Since the bottom sand for aquariums described in [3] above uses a mineral flocculant, it does not affect aquatic organisms.
本発明の水槽用底砂はゼオライト粒に凝集剤が配合されている。 The bottom sand for an aquarium of the present invention contains a flocculant in zeolite particles.
ゼオライト粒は粒状体である。例えば、ゼオライト粉末を焼成して造粒したものが用いられ、なかでも７００〜８５０℃で焼成したゼオライト粒は細孔構造を維持して水の浄化能力が優れている。粒の形状は球形、不定形等任意形状のものを使用できる。粒の大きさも限定されず、観賞魚用水槽では直径１〜５ｍｍのものが好まれる。また、ゼオライトの種類も限定されず、天然、人工の別も問わない。 Zeolite grains are granular. For example, a powder obtained by firing and granulating zeolite powder is used. Among these, the zeolite particles fired at 700 to 850 ° C. maintain the pore structure and have an excellent water purification ability. The shape of the grains can be any shape such as a sphere or an indefinite shape. The size of the grains is not limited, and an aquarium fish tank with a diameter of 1 to 5 mm is preferred. Moreover, the kind of zeolite is not limited, either natural or artificial.
凝集剤は、ゼオライト粒から脱落した微粉末を水中で凝集させてフロックを形成するために配合される。微粉末が凝集してフロックを形成すると沈降速度が早くなるので、水中を浮遊する微粉末による白濁を短時間で解消することができる。前記凝集剤の種類は水棲生物の生息環境を悪化させない限り限定されないが、鉱物由来の凝集剤が好ましい。特に火山性土壌のシラスは凝集能力が高く、かつ水棲生物に影響を及ぼさない点で推奨できる。前記凝集剤は粉末状に加工したものが使用され、ゼオライトの微粉末と均一に混合できる微粉末が好ましく、粒径１５０〜２００μｍの微粉末が好ましい。 The flocculant is blended in order to agglomerate the fine powder dropped from the zeolite grains in water to form a floc. When the fine powder aggregates to form a floc, the sedimentation speed increases, so that white turbidity due to the fine powder floating in water can be eliminated in a short time. The type of the flocculant is not limited as long as it does not deteriorate the aquatic environment of aquatic organisms, but a mineral-derived flocculant is preferable. In particular, volcanic soil shirasu is recommended because it has a high coagulation ability and does not affect aquatic organisms. The flocculant processed into a powder is used, and a fine powder that can be uniformly mixed with the fine powder of zeolite is preferable, and a fine powder having a particle size of 150 to 200 μm is preferable.
前記ゼオライト粒と凝集剤の配合割合は、ゼオライト粒１００質量部に対して凝集剤０．０１〜０．１質量部が好ましい。ゼオライト微粉末の量は水槽用底砂の製造工程や輸送状況によって変動するが、凝集剤が０．０１質量部未満では不足するおそれがある。一方、０．１質量を配合すれば十分であるからそれを超える配合はコスト高となる。また、凝集剤量の増大に伴ってフロックの発生量も増えるので、観賞魚用水槽の美観を損なうおそれがある。特に好ましい配合割合はゼオライト粒１００質量部に対して凝集剤０．０１〜０．０４質量部である。上記のゼオライト粒の１００質量部には粒状体から脱落した微粉末も含まれている。上記の配合割合はゼオライト粒と凝集剤とを混合する際の計量質量である。 The blending ratio of the zeolite particles and the flocculant is preferably 0.01 to 0.1 parts by mass of the flocculant with respect to 100 parts by mass of the zeolite particles. Although the amount of zeolite fine powder varies depending on the manufacturing process and transportation status of the bottom sand for aquarium, there is a fear that the flocculant is less than 0.01 parts by mass. On the other hand, since it is sufficient if 0.1 mass is blended, the blending exceeding it is costly. Moreover, since the generation amount of flocs increases as the amount of the flocculant increases, the beauty of the aquarium fish tank may be impaired. A particularly preferable blending ratio is 0.01 to 0.04 parts by mass of the flocculant with respect to 100 parts by mass of the zeolite particles. 100 parts by mass of the above zeolite particles also include fine powders that have fallen off from the granules. The above blending ratio is a measured mass when mixing the zeolite particles and the flocculant.
前記水槽用底砂はゼオライト粒と凝集剤は均一に混合されていることが好ましい。凝集反応は凝集剤が水に接触すると瞬時に開始するので、凝集剤が偏在していると凝集剤同士でフロックを形成してしまい、ゼオライト微粉末を凝集させるために必要な凝集剤量が不足するおそれがある。従って、ゼオライト微粉末を少量の凝集剤で効率良く凝集させるためには両者が均一に混合されていることが好ましい。凝集剤によってフロックとなったゼオライト微粉末は沈降速度を速めて短時間で槽底に沈んでいく。また、ゼオライト微粉末に対して過剰量の凝集剤は水中を浮遊したままではなく、凝集剤同士でフロックを形成して短時間で槽底に沈んでいく。水槽内は自然環境よりも生物の存在密度が高いので、たとえ鉱物由来の凝集剤であっても微粉末が浮遊していない状態が好ましい。こうしてゼオライトの微粉末および凝集剤が短時間で槽底に沈み、水が透明になる。 In the bottom sand for the water tank, it is preferable that the zeolite particles and the flocculant are uniformly mixed. The flocculent reaction starts instantly when the flocculant comes into contact with water. If the flocculant is unevenly distributed, flocs form with each other, and the amount of flocculant necessary to agglomerate the zeolite fine powder is insufficient. There is a risk. Therefore, in order to efficiently agglomerate the zeolite fine powder with a small amount of a flocculant, it is preferable that both are uniformly mixed. The zeolite fine powder that has flocated by the flocculant sinks to the bottom of the tank in a short time by increasing the sedimentation speed. Further, an excessive amount of the flocculant with respect to the zeolite fine powder does not remain floating in water, but flocs are formed between the flocculants and sink to the bottom of the tank in a short time. Since the existence density of living organisms is higher in the water tank than in the natural environment, it is preferable that the fine powder is not suspended even if it is a mineral-derived flocculant. Thus, the fine zeolite powder and the flocculant sink to the bottom of the tank in a short time, and the water becomes transparent.
前記水槽用底砂は、水槽内の水でフロックを形成して槽底に沈めても良いし、水槽に投入する前に水洗してフロックを形成させ、フロックを洗い流した後に水槽に投入しても良い。いずれの場合も、水槽用底砂を水に接触させた後は速やかに攪拌し、ゼオライト微粉末の凝集する前に凝集剤同士の凝集で凝集剤が消費され尽くさないようににすることが好ましい。 The tank bottom sand may form a flock with the water in the aquarium and sink to the bottom of the tank, or may be washed with water before being put into the aquarium to form a flock, and then washed off the flock and then thrown into the aquarium. Also good. In any case, it is preferable that the bottom sand for the aquarium is brought into contact with water and stirred rapidly so that the flocculant is not consumed due to aggregation between the flocculants before the zeolite fine powder is aggregated. .
本発明の水槽用底砂は、ゼオライト粒および凝集剤以外にも石、砂、ソイルなどを配合することができる。これらを配合しても凝集剤によるフロック形成効果は損なわれることはなく、水の濁りを短時間で解消できる。 The bottom sand for an aquarium of the present invention can contain stones, sand, soil and the like in addition to the zeolite particles and the flocculant. Even if these are blended, the floc forming effect by the flocculant is not impaired, and the turbidity of water can be eliminated in a short time.
〈実施例〉
ゼオライト粒は、ゼオライト粉末を８００℃で焼成して造粒し、直径３〜５ｍｍの粒状体を選別した。
<Example>
Zeolite grains were granulated by calcining zeolite powder at 800 ° C. to select granules having a diameter of 3 to 5 mm.
凝集剤として、比重０．９５３０、平均粒径１８０μｍの天然シラスを用いた。前記天然シラスは、無臭で水に不溶の淡灰色粉末であり、フロックを形成して沈殿しても底砂として違和感の無い色彩である。前記シラスの組成はＮａ２Ｏ３：３０．８８％、ＣａＯ：２１．９０％、ＳＯ３：１９．４２％、Ａｌ２Ｏ３：１３．７７％、ＳｉＯ２：１０．８３％、Ｆｅ２Ｏ３：１．３９％、ＭｇＯ：０．９７％、Ｋ２Ｏ：０．５９％、Ｐ２Ｏ５：０．２５％であり、０．１％液はｐＨ６．１である。前記成分中のＰ２Ｏ５はシラス由来の酸化成分であり、溶出試験において水に溶出しないことを確認した。 As a flocculant, natural shirasu having a specific gravity of 0.9530 and an average particle size of 180 μm was used. The natural shirasu is a light gray powder that is odorless and insoluble in water, and even if it forms a floc and settles, it has a color that does not give a sense of incongruity as bottom sand. The composition of the shirasu was Na 2 O 3 : 30.88%, CaO: 21.90%, SO 3 : 19.42%, Al 2 O 3 : 13.77%, SiO 2 : 10.83%, Fe 2 O 3 : 1.39%, MgO: 0.97%, K 2 O: 0.59%, P 2 O 5 : 0.25%, and the 0.1% solution has a pH of 6.1. It was confirmed that P 2 O 5 in the component is an oxidizing component derived from Shirasu and does not dissolve in water in the dissolution test.
水槽用底砂は、前記ゼオライト粒１００質量部に対して凝集剤０．０４質量部を配合し、攪拌混合して作製した。さらに、トラックで大阪−東京間を往復輸送し、ゼオライト粒の表面を砕いてゼオライト微粉末を生じせた。

上記ゼオライト粒のみで水槽用底砂を作製し、実施例と同じ条件でゼオライト粒の表面を砕いてゼオライト微粉末を生じせた。
〈評価〉
実施例および比較例の水槽用底砂１２００ｇをそれぞれ１２Ｌの水道水を入れた水槽に投入し静置した。また、各水槽には、観賞魚飼育で使用する外掛け式フィルターを取り付けて水を循環濾過した。
The bottom sand for aquarium was prepared by mixing 0.04 parts by mass of a flocculant with 100 parts by mass of the zeolite particles and stirring and mixing them. Furthermore, the truck was transported back and forth between Osaka and Tokyo, and the surface of the zeolite particles was crushed to produce fine zeolite powder.
<Comparative example>
Water tank bottom sand was prepared using only the zeolite particles, and the surface of the zeolite particles was crushed under the same conditions as in the examples to produce zeolite fine powder.
<Evaluation>
The bottom sand for water tanks of Examples and Comparative Examples (1200 g) was put into water tanks each containing 12 L of tap water and allowed to stand. Each tank was fitted with an external filter used for breeding ornamental fish, and water was circulated and filtered.
静置開始から２４時間経過後に、濁度計にて水の濁度をを比較したところ、実施例は０．２７ＮＴＵであり、比較例は４．８１ＮＴＵであった。底砂投入前の水槽内の水道水の濁度は０．３４でＮＴＵであり、実施例は２４時間で水道水と同等以上に透明になったことを示している。さらに、比較例の底砂を投入した水槽が実施例と同等の透明度になるまで静置を続けたところ、要した時間は１４日であった。 When the turbidity of water was compared with a turbidimeter after 24 hours from the start of standing, the example was 0.27 NTU and the comparative example was 4.81 NTU. The turbidity of tap water in the water tank before the bottom sand was 0.34, which was NTU, and the example shows that the turbidity became more than equivalent to tap water in 24 hours. Furthermore, when it left still until the water tank which injected | thrown-in the bottom sand of a comparative example became transparency equivalent to an Example, the time required was 14 days.
