Description
本発明は、土壌に簡単に敷設して使用する水溶性シートに関し、特に、適用された畑などの土壌において、人体に影響を及ぼす土壌中に含まれる有害成分を吸着・固定化することができ、かつ使用に際しては、敷設作業が非常に簡便にでき、製作においては、粉末体の飛散を防止することができると共に、土質に適応して有害成分に対する吸着性能や薬剤処理の変更を自由に設計可能となし得る多機能水溶性シートに関する。 The present invention relates to a water-soluble sheet that can be easily laid and used in soil, and in particular, can be used to adsorb and immobilize harmful components contained in soil that affects the human body in soil such as applied fields. In use, the laying work can be done very easily, and in the production, the powder can be prevented from scattering, and the adsorption performance for harmful components and changes in chemical treatment can be freely designed to adapt to the soil. It relates to a multifunctional water-soluble sheet that can be made possible.
これまで、土壌中のダイオキシン類、使用禁止となった農薬、揮発性有機物質、重金属、その他有害物質を吸着する目的として、土壌を入れ替える方法や土壌を洗浄し活性炭等の吸着剤に処理した水を付着させ回収する方法、また、有害物質を分解する微生物を土壌と撹拌する方法、酸化還元剤の地盤注入で分解する方法、土壌の焼却方法などがあった。しかし、これらの方法は、土壌の入れ替え、洗浄、分解無毒化等に多額の費用を要すると共に処理に数ヶ月から年相当の整備期間を必要とするものであった。そして土壌を洗浄する場合には、シルト分が除去され地盤が不安定化し、また植物が必要とする栄養分なども除去されてしまう為、この方法は、農業に使用する土壌には不向きであり使用上の問題を残していた。
上記に変わる方法として、土壌中の有害物質を低減または土中に固定化する目的として、活性炭を代表とする吸着剤の微粉末を土壌に散布する方法が研究され、実用化された。しかしながら、吸収剤の粉末が飛散し粉塵対策の必要であり、粉塵の飛散防止対策のため覆いを施こさなければならないなどの諸費用が掛かるものであった。この覆いを施した場合でも、吸着剤の微粉末は比重が軽い微粒子であるため、揮発性成分飛散防止や粉塵防御のために施設された簡易ハウス内において特に粉塵爆発の危険の増大、また屋外では微粉末が舞い上がり飛散するため、均一な散布が難しく、効果的な散布ができないという問題を残していた。
また、従来の散布方法も多量の水を必要とするほか、界面活性剤の親水化加工した活性炭入り水を散布した場合、土壌が泡立ったり、水分が過剰気味となり、これにより土壌が粘土化し、次の工程作業への移行がしにくいという問題もあるなどの理由により、作業者の多大な負担となっていた。
作業者も高齢化社会となり、農業の例では農業従事者の農薬散布、改質剤散布などの作業工程は身体的負担となっていた。
現在、カートリッジに詰めた活性炭単体を用いる方法や有害物質を除去する為に活性炭を付着し、回収後、焼却廃棄または再生する目的の非崩壊性の活性炭シートは存在する。
この方法は、土壌を水洗浄し、有害物質を活性炭に吸着させて、回収する方法であり、活性炭の再生に多量の薬剤を使用するので環境負荷も高く、やはり期間と費用がかかる方法であり、生物に必要な土壌中の成分も除去する可能性があり、土壌再生資材として向いていないという問題があった。
また、多くの工程を伴う薬剤処理には一度で済む方法がなく、土壌に対し均一に散布される方法もなかった。
水田など水の多く存在する特殊場所には、発泡性薬錠剤や水溶性個袋入り薬剤など存在するがも広い面積に対する土壌処理には適さない。
現在、崩壊または分解するシートに微粉砕物を添着する方法があっても、微粉砕物の性能を落とさず、高目付に微粉砕物を均一に付着できるシート化できなかった。
So far, water used to adsorb dioxins in soil, agricultural chemicals banned from use, volatile organic substances, heavy metals, and other harmful substances, as well as methods for replacing soil and washing soil and treating it with an adsorbent such as activated carbon. There are a method of attaching and recovering, a method of stirring microorganisms that decompose harmful substances with soil, a method of decomposing by ground injection of a redox agent, and a method of incinerating soil. However, these methods require a large amount of money for soil replacement, washing, detoxification and the like, and the treatment requires several months to a yearly maintenance period. And when washing the soil, the silt content is removed, the ground becomes unstable, and the nutrients required by the plant are also removed, so this method is not suitable for agricultural soil. Was leaving the problem above.
As a method instead of the above, for the purpose of reducing or immobilizing harmful substances in the soil, a method of spraying a fine powder of an adsorbent typified by activated carbon on the soil has been studied and put into practical use. However, the powder of the absorbent is scattered and it is necessary to take measures against dust, and it takes various costs such as covering the dust to prevent dust from scattering. Even with this covering, the adsorbent fine powder is a fine particle with a low specific gravity, which increases the risk of dust explosion, especially in a simple house where volatile components are scattered and dust is protected. However, because fine powder soared and scattered, it was difficult to evenly spread, and there was a problem that it was impossible to spread effectively.
In addition, the conventional spraying method also requires a large amount of water, and when sprayed with water containing activated carbon that has been hydrophilized with a surfactant, the soil becomes foamy or the moisture becomes excessively small, which makes the soil clay, For example, there is a problem that it is difficult to shift to the next process work.
Workers have also become an aging society, and in the case of agriculture, work processes such as spraying agricultural chemicals and spraying modifiers have become a physical burden.
Currently, there are non-disintegrating activated carbon sheets for the purpose of using activated carbon alone packed in a cartridge or attaching activated carbon in order to remove harmful substances, and then incinerating or recycling after collection.
In this method, the soil is washed with water, and harmful substances are adsorbed on activated carbon and recovered, and a large amount of chemicals are used to regenerate the activated carbon, so the environmental load is high, and it is also a time-consuming and expensive method. In addition, there is a possibility that components in the soil necessary for living organisms may be removed, and there is a problem that it is not suitable as a soil regeneration material.
In addition, there is no method that can be used only once for the chemical treatment involving many steps, and there is no method that is uniformly applied to the soil.
In special places where there is a lot of water, such as paddy fields, effervescent medicine tablets and water-soluble medicines in individual bags are present, but they are not suitable for soil treatment over a large area.
At present, even if there is a method of attaching a finely pulverized material to a sheet that disintegrates or decomposes, the performance of the finely pulverized material is not deteriorated, and a sheet that can uniformly adhere the finely pulverized material with high basis weight cannot be obtained.
本発明は、高齢化社会に向けて、従事者の作業工程の簡便化を図って身体的負担を軽減させ、微粉末吸着剤の飛散防止および微粉末の粉塵爆発防止を図り、作業者及び近隣の安全対策を向上させ、水溶性シートをして、多目的な仕様設計可能な水溶性吸着シートとの多機能水溶性シートとして提供することを目的とする。
上記の課題を解決するため、本発明は、散水又は降雨が少量の場合であっても水溶分解を確実にし、少なくとも添付された吸着剤等を機能させることのできように、少量の水量で吸着剤の添付された水溶性シートを水溶分解して、土壌中の有害物質を吸着固定することのできる多機能水溶性シートを提供することである。
また、作業の工程を簡便化するため土壌改良処理に使用する薬剤を添加含有する多機能水溶性シートを提供することである。
本発明によれば、これまで薬剤を均一散布しにくい傾斜地であっても、薬剤を均一に分散配布することのできる多機能水溶性シートをも提供することができる。

According to the present invention, it is possible to provide a multifunctional water-soluble sheet that can evenly distribute and distribute a drug even on a slope where it is difficult to uniformly spray the drug until now.
本発明は、上記従来技術の課題及び現状に鑑み、これらを解決するものであり、今回、提案する多機能水溶性シートは雨水などの少量の水分で微粉末の吸着剤または機能を持つ添加剤を、地下水汚染の恐れのある界面活性剤を用いずに効率よく土壌に分散させ、土壌撹拌後または層状に埋設後、吸収剤と土壌が適度に密着することにより吸収剤の再飛散を防止、有害物質を吸着剤に固定し、植物への吸収を阻害や地下水への汚染を防止することを第一の目的とし、本発明は、簡便で吸着効率を阻害しない水溶性吸着シートを提供する。 The present invention is to solve these problems in view of the above-mentioned prior art and the present situation. The proposed multifunctional water-soluble sheet is an additive having a fine powder adsorbent or function with a small amount of moisture such as rainwater. Can be efficiently dispersed in the soil without using a surfactant that may contaminate groundwater, and after the agitation of the soil or after being buried in layers, the absorbent and the soil are in close contact with each other to prevent re-scattering of the absorbent. The first object of the present invention is to fix a harmful substance to an adsorbent, thereby inhibiting absorption into plants and preventing contamination to groundwater.

肥料を添加した土壌に下記の３種類のシートを作成し、それぞれに作成したシートを添加し、きゅうり育成実験を行った。
三島製紙(株)「現日本製紙パピリア(株)」の水溶紙３０ＭＤＰ(速崩壊性カルボキシメチルセルロース類シート)を使用し、比表面積が１０００ｍ２／ｇであり、２００メッシュを通過する粒子径を有すると共に、その粒子密度が、平均粒度１００μm以下で、その割合が粒度重量の８０％を超える仕様である異なるメーカーの市販活性炭Ａ、市販活性炭Ｂを用い、９０％エチルアルコール水溶液の中にそれぞれ活性炭９５部、ポリビニルアルコール５部を入れ攪拌し各加工液を調整した。加工液を水溶紙の表面に均一になる様散布後乾燥し、それぞれ活性炭含有量１００ｇ／ｍ２になる様に活性炭シートＡ、活性炭シートＢ作成し、活性炭シートなし場合との比較を比較する。
活性炭シートなし（活性炭無添加）のとき、１００％で濃度変化はなかったが、活性炭添加に場合（活性炭シートＡ又は活性炭シートＢ）は濃度比較値３０〜４０％となり、大幅に低減することが判明した。さらに、活性炭の量について、１００ｇ／ｍ２、２００ｇ／ｍ２とで対比試験をしたところ、１００ｇ／ｍ２の場合の濃度比較値は３０〜４０％であったのに対し、２００ｇ／ｍ２の場合の濃度比較値は略１８％となり、活性炭単体で用いるのと同等な性能を示し、シート化による影響もなく、活性炭目付けを増量すると、ディルドリンの量を減量することが判った。
きゅうりの成長阻害もなく、シートの無添加と比べても成長速度の差異は認められなかった。
