Description
本発明は、土壌浄化剤組成物に関し、より詳細には、油類によって汚染された土壌、特に重油等の石油系化合物、中でもＣ重油に汚染された土壌を洗浄するための土壌浄化剤組成物に関する。 The present invention relates to a soil cleaner composition, and more particularly, a soil cleaner composition for cleaning soil contaminated by oils, particularly petroleum-based compounds such as heavy oil, especially soil contaminated with C heavy oil. About.
近年、ガソリンスタンドや工場からの敷地跡地に存在する、長期にわたって漏出した有機物で汚染された土壌が社会問題となっており、早急な汚染土壌の浄化対策が求められている。
従来から、油汚染土壌の浄化方法としては、例えば、掘削した油含有土壌を加熱して油を除去する方法、高圧空気で油含有土壌から油を剥離し、微生物を用いて油を分解する方法、土壌洗浄法などが提案されている（特許文献１参照）。このうち土壌洗浄法は、コストや環境の面で優れた土壌浄化方法であり、従来から、例えば浄化薬剤として界面活性剤を用いた土壌洗浄剤や土壌浄化方法が報告されている（特許文献１〜３参照）。
In recent years, soil contaminated with organic matter leaked over a long period of time from the site of a petrol station or factory has become a social problem, and urgent measures to clean up contaminated soil are required.
Conventionally, as a purification method of oil-contaminated soil, for example, a method of removing oil by heating excavated oil-containing soil, a method of peeling oil from oil-containing soil with high-pressure air, and decomposing oil using microorganisms A soil cleaning method has been proposed (see Patent Document 1). Among these, the soil cleaning method is a soil purification method that is excellent in terms of cost and environment, and conventionally, for example, a soil cleaning agent and a soil purification method using a surfactant as a purification agent have been reported (Patent Document 1). To 3).
本発明は、前記従来における諸問題を解決し、以下の目的を達成することを課題とする。即ち、本発明は、油類によって汚染された土壌、特に重油等の石油系化合物、中でもＣ重油に汚染された土壌を効果的に洗浄することのできる、優れた土壌浄化剤組成物を提供することを目的とする。 An object of the present invention is to solve the conventional problems and achieve the following objects. That is, the present invention provides an excellent soil purifier composition capable of effectively washing soil contaminated with oils, particularly petroleum-based compounds such as heavy oil, especially soil contaminated with C heavy oil. For the purpose.
本発明者らは、前記目的を達成すべく鋭意研究を重ねた結果、特定のポリオキシアルキレンアルキルエーテルと、有機アミン化合物とを含有する土壌浄化剤組成物を用いることで、重油、特に粘度が高く洗浄が困難なＣ重油に汚染された土壌から、効果的に重油を除去することができることを見出し、本発明の完成に至った。
前記したような、従来の土壌洗浄剤や土壌浄化方法（特開２００４−３２２０７３号公報、特開２００３−１１９４９５号公報、特開２００１−１７９５５号公報参照）では、例えば、土壌を攪拌せずに現位置で洗浄する際や、粘度が高く洗浄が困難なＣ重油を洗浄する際などにおいては、十分な洗浄力が得られないなどの問題があった。これに対し、本発明の土壌浄化剤組成物は、汚染土壌の洗浄性、及び、土壌中での通液性に優れるものであり、したがって、土壌を攪拌せずに現位置で洗浄する際や、粘度が高く洗浄が困難なＣ重油を洗浄する際などにも、十分な洗浄力を発揮することができるという利点がある。
As a result of intensive studies to achieve the above object, the present inventors have used heavy oil, particularly viscosity, by using a soil purifier composition containing a specific polyoxyalkylene alkyl ether and an organic amine compound. The present inventors have found that heavy oil can be effectively removed from soil contaminated with C heavy oil, which is difficult to wash, and completed the present invention.
In the conventional soil cleaning agent and the soil purification method as described above (see JP 2004-322073 A, JP 2003-119495 A, JP 2001-17955 A), for example, without stirring the soil When cleaning at the current position or when cleaning C heavy oil, which has a high viscosity and is difficult to clean, there was a problem that sufficient cleaning power could not be obtained. On the other hand, the soil purifier composition of the present invention has excellent detergency for contaminated soil and liquid permeability in the soil, and therefore, when the soil is washed at the current position without stirring. Also, there is an advantage that sufficient detergency can be exerted when washing C heavy oil, which has a high viscosity and is difficult to wash.

When the content of the component (B) with respect to the amount of the active ingredient is less than 5% by mass, a desired degree of detergency against heavy oil, particularly C heavy oil may not be obtained, and when it exceeds 40% by mass, The component (A) having a desired level may not be blended. On the other hand, when the content of the component (B) with respect to the amount of the active ingredient is within a more preferable range, the component (A) with a desired degree can be blended, which is better for heavy oil, particularly C heavy oil. This is advantageous in that a detergency can be obtained.
また、前記土壌浄化剤組成物が（Ａ１）成分及び（Ａ２）成分の両者を含有する場合、前記（Ａ）成分の含有量（前記（Ａ１）成分及び前記（Ａ２）成分の合計含有量）に対する、前記（Ａ２）成分の含有量としては、０．５〜１０質量％が好ましく、１〜７質量％がより好ましく、２〜５質量％が更に好ましい。前記（Ａ）成分の含有量に対する前記（Ａ２）成分の含有量が、０．５質量％未満であると、（Ａ２）成分の重油、特にＣ重油の分散性能による洗浄力向上効果が得られないことがあり、１０質量％を超えると、相対的に（Ａ１）成分の配合量が減るため重油の可溶化力が低下し、洗浄力が得られないことがある。一方、前記（Ａ）成分の含有量に対する前記（Ａ２）成分の含有量が、更に好ましい範囲内であると、重油の分散性と可溶化力のバランスがとれ、洗浄力がさらに良好となる点で、有利である。 Moreover, when the said soil purifier composition contains both (A1) component and (A2) component, content of said (A) component (total content of said (A1) component and said (A2) component) The content of the component (A2) is preferably 0.5 to 10% by mass, more preferably 1 to 7% by mass, and still more preferably 2 to 5% by mass. When the content of the component (A2) relative to the content of the component (A) is less than 0.5% by mass, an effect of improving the detergency due to the dispersion performance of the heavy oil of the component (A2), particularly C heavy oil, is obtained. In some cases, if the amount exceeds 10% by mass, the blending amount of the component (A1) is relatively reduced, so that the solubilizing power of heavy oil is reduced and the detergency may not be obtained. On the other hand, when the content of the component (A2) relative to the content of the component (A) is within a more preferable range, the balance between the dispersibility of the heavy oil and the solubilizing power can be achieved, and the detergency can be further improved. It is advantageous.
更に、（Ｃ）成分を含有する場合、有効成分量（（Ａ）成分の含有量（（Ａ１）成分と（Ａ２）成分の合計含有量）と（Ｂ）成分と（Ｃ）成分の合計含有量）に対する（Ｃ）成分の含有量としては、０．０８〜１２質量％が好ましく、０．１〜８質量％がより好ましく、０．４〜４質量％が更に好ましい。
前記有効成分量に対する前記（Ｃ）の含有量が、０．０８質量％未満であると、（Ｃ）成分添加の効果が十分に発揮されないことがあり、前記有効成分量に対する前記（Ｃ）の含有量が、１２質量％を超えると、洗浄性が低下することがある。
Further, when the component (C) is contained, the effective component amount (the content of the component (A) (the total content of the components (A1) and (A2)), the total content of the component (B) and the component (C) As content of (C) component with respect to (quantity), 0.08-12 mass% is preferable, 0.1-8 mass% is more preferable, 0.4-4 mass% is still more preferable.
When the content of (C) with respect to the amount of the active ingredient is less than 0.08% by mass, the effect of adding the component (C) may not be sufficiently exhibited. If the content exceeds 12% by mass, the detergency may be deteriorated.
また、前記（Ｃ）成分の種類、添加量としては、土壌浄化剤組成物溶液中の目的とするミセルサイズに応じて適宜選択することができるが、液外観が透明にならない範囲で（Ｃ）成分を添加することが好ましい。
前記ミセルサイズとしては、特に制限はなく、目的に応じて適宜選択することができるが、２００〜７００ｎｍが好ましい。前記ミセルサイズが７００ｎｍより大きいと、通液性向上効果が十分に発揮されないことがあり、前記ミセルサイズが２００ｎｍ未満であると、洗浄性、特にＣ重油の洗浄性が悪化することがある。一方、前記好ましい範囲内であると、土壌浄化剤組成物の洗浄性を維持しながら土壌中の通液性をより向上させる点で、有利である。
前記ミセルサイズは、例えば、動的光散乱光度計ＤＬＳ８０００（大塚電子製）を用いて、土壌浄化洗浄剤の流体力学的半径Ｒｈを測定することができる。
Moreover, as a kind and addition amount of said (C) component, although it can select suitably according to the objective micelle size in a soil purifier composition solution, (C) in the range by which a liquid external appearance does not become transparent. It is preferred to add the components.
There is no restriction | limiting in particular as said micelle size, Although it can select suitably according to the objective, 200-700 nm is preferable. When the micelle size is larger than 700 nm, the effect of improving liquid permeability may not be sufficiently exhibited, and when the micelle size is less than 200 nm, the detergency, particularly the detergency of C heavy oil may be deteriorated. On the other hand, it is advantageous in the said preferable range at the point which improves the liquid permeability in soil, maintaining the detergency of a soil purifier composition.
The micelle size can be measured, for example, by using a dynamic light scattering photometer DLS8000 (manufactured by Otsuka Electronics), the hydrodynamic radius Rh of the soil purification detergent.

<Application method>
The soil purifier composition can be used, for example, in various soil purification methods as shown below, and the method is not particularly limited and can be appropriately selected depending on the purpose.
The soil purification method includes a method for purifying contaminated soil in situ (hereinafter sometimes referred to as “in-situ purification method”) and a method for purifying excavated contaminated soil (hereinafter referred to as “excavation purification method”). Can be broadly divided. The in-situ purification method is a method to purify contaminated soil in-situ, a method of injecting a cleaning agent from an injection well provided near the contaminated area (chemical injection method), and a contaminated soil using a mixing machine such as a stabilizer. For example, there is a method of mixing a cleaning agent with a cleaning agent. The excavation and purification method is a method in which excavated contaminated soil is transported to a purification treatment plant for cleaning.
原位置浄化工法の一種である薬剤注入工法は、特殊な装置が不要であり、汚染土壌を原位置で浄化するためコスト的に有利である一方、洗浄時に機械的攪拌力を作用させることができないため、使用する浄化剤には高い洗浄力が求められる。
薬剤注入工法は、汚染領域の近傍に注入井戸と揚水井戸を設けて、注入井戸から浄化剤を含む液体（以下、「浄化用流体」と称することがある）を注入して揚水井戸から処理液を揚水することにより、注入井戸から揚水井戸へ向かう地下水の流れを形成し、汚染土壌の浄化を行う工法である。なお、注入井戸と揚水井戸は兼用とすることもできる。
The chemical injection method, which is a type of in-situ purification method, does not require a special device and is advantageous in terms of cost because it purifies the contaminated soil in-situ, but it does not allow the mechanical stirring force to act during cleaning. Therefore, a high cleaning power is required for the purifier used.
In the chemical injection method, an injection well and a pumping well are provided in the vicinity of the contaminated area, and a liquid containing a purifying agent (hereinafter sometimes referred to as “purifying fluid”) is injected from the injection well and the treatment liquid is supplied from the pumping well. Is a method of purifying contaminated soil by forming groundwater flow from the injection well to the pumping well. In addition, the injection well and the pumping well can be combined.

注入井戸５の上端には移送ラインＬ１を介して薬剤混合供給装置７が連結されている。これにより、前記土壌浄化剤組成物を含む浄化用流体（薬剤）が薬剤混合供給装置７から注入井戸５を通って飽和層２に注入される。なお、薬剤混合供給装置７の構成は特に制限されないが、例えば、薬剤タンク、及び、注入ポンプなどを含んで構成することができる。
注入井戸５から飽和層２に注入された薬剤は、地下水の流れＡに沿って飽和層２中を移動して、有機物層３に到達する。そして、有機物層３中の土粒子に付着している有機物が該薬剤の作用により土粒子から剥離することにより、汚染土壌の浄化が行われる。そして、剥離した有機物は地下水の流れＡに沿って揚水井戸６まで移動する。
揚水井戸６の上端には揚水ラインＬ２を介して揚水ポンプ８が連結されており、この揚水ポンプ８により揚水（薬剤、水、有機物の混合液）が地上に汲み上げられる。採取された揚水は揚水ポンプ８からラインＬ３を通って油水分離槽９に送られ、揚水が、薬剤と有機物の混合液Ａ及び薬剤と水の混合液Ｂに分離される。分離された混合液Ａは廃棄ラインＬ４から回収される。一方、分離された混合液Ｂは、ラインＬ５を通って薬剤混合供給装置７へ送られ、薬剤の濃度調整を行った後に再利用される。
FIG. 1 is an explanatory view showing a preferred example of a chemical injection method using the soil purifier composition. The purification system 100 shown in FIG. 1 includes an organic substance layer (contaminated layer) present in the saturated layer 2 in the target contaminated region where the unsaturated layer (non-aquifer) 1 and the saturated layer (aquifer) 2 exist. This is a system for purifying 3 in-situ.

The injection well 5 and the pumping well 6 are respectively provided so as to reach below the groundwater level 4, that is, their lower ends are located below the groundwater level 4. A dynamic gradient of groundwater from the well 5 to the pumping well 6 is formed.
A drug mixing and supplying device 7 is connected to the upper end of the injection well 5 via a transfer line L1. As a result, a purification fluid (medicine) containing the soil purification agent composition is injected into the saturated layer 2 from the drug mixture supply device 7 through the injection well 5. The configuration of the drug mixing and supplying device 7 is not particularly limited, but may be configured to include, for example, a drug tank and an infusion pump.
The drug injected into the saturated layer 2 from the injection well 5 moves through the saturated layer 2 along the groundwater flow A and reaches the organic material layer 3. And organic substance adhering to the soil particle in the organic substance layer 3 peels from soil particle by the effect | action of this chemical | medical agent, and purification of contaminated soil is performed. Then, the peeled organic matter moves to the pumping well 6 along the flow A of the groundwater.
A pumping pump 8 is connected to the upper end of the pumping well 6 through a pumping line L2, and the pumping pump 8 pumps pumped water (mixed liquid of medicine, water and organic matter) to the ground. The collected pumped water is sent from the pumping pump 8 through the line L3 to the oil / water separation tank 9, and the pumped water is separated into the liquid mixture A of the medicine and organic matter and the liquid mixture B of the medicine and water. The separated mixed solution A is recovered from the waste line L4. On the other hand, the separated mixed solution B is sent to the drug mixture supply device 7 through the line L5, and is reused after adjusting the concentration of the drug.
図１に示すような実施形態によれば、対象汚染領域において、注入井戸５、及び、揚水井戸６をそれぞれ地下水位４よりも下方に達するように設け、注入井戸５から揚水井戸６へ向かう地下水の動水勾配を形成することにより、浄化効率を一層向上させることができる。即ち、注入井戸５から薬剤を添加することにより、これらの薬剤は地下水の流れＡに沿って十分に速やかに移動することができるようになり、薬剤の到達範囲をより拡大することができるようになる。
また、薬剤注入工法による汚染土壌浄化を更に促進する方法として、汚染領域の下部から注入井戸を通して空気を吹き込む方法、汚染領域をスチームにより加熱する方法、浄化用流体が注入された位置とは異なる位置から土壌内の地下水を真空吸引する方法、汚染領域に超音波を付与する方法、注入井戸から注入する浄化用流体に一定の、又は、間欠的な圧力をかける方法などを併用することができる。なお、前記土壌浄化剤組成物を用いた土壌浄化方法は上記実施形態に限定されるものではない。
According to the embodiment shown in FIG. 1, the injection well 5 and the pumping well 6 are provided so as to reach below the groundwater level 4 in the target contaminated area, and the groundwater heading from the injection well 5 to the pumping well 6. The purification efficiency can be further improved by forming a hydrodynamic gradient. That is, by adding chemicals from the injection well 5, these chemicals can move sufficiently quickly along the flow A of the groundwater, so that the reach of the chemicals can be further expanded. Become.
In addition, as a method of further promoting the purification of contaminated soil by the chemical injection method, a method of blowing air from the lower part of the contaminated area through an injection well, a method of heating the contaminated area with steam, and a position different from the position where the purification fluid is injected A method of vacuum suction of groundwater in soil, a method of applying ultrasonic waves to a contaminated area, a method of applying a constant or intermittent pressure to a purification fluid injected from an injection well, and the like can be used in combination. In addition, the soil purification method using the said soil purification agent composition is not limited to the said embodiment.
前記土壌浄化剤組成物は、前記した何れの工法に対しても適用し得るが、前記土壌浄化剤組成物は、重油、特に粘度が高く洗浄が困難なＣ重油の洗浄力に優れ、また、機械的攪拌力を加えなくとも高い洗浄力を示すことから、前記した薬剤注入工法への使用に、特に好適である。 The soil cleaner composition can be applied to any of the above-described methods, but the soil cleaner composition is excellent in detergency of heavy oil, particularly C heavy oil, which has a high viscosity and is difficult to clean, Since it exhibits a high detergency even without applying mechanical stirring force, it is particularly suitable for use in the above-described drug injection method.

-Measurement of soil heavy oil contamination rate (detergency evaluation)-
The prepared model heavy oil-contaminated soil 50 g was packed into a cylindrical column 21 (inner diameter 3 cm, length 4 cm), and the apparatus was set as shown in FIG. The cylindrical column 21 was used as a column for enclosing soil, and a silicon tube 22 (inner diameter 3 mm) was used as a tube. A 500 ml beaker 23 was used as a receiving tank. The soil purifier composition was injected from the lower entrance of the column 21 through the silicon tube 22. At this time, vacuum suction was performed from the tube outlet attached to the column outlet, and the tube was sealed up to the tube outlet. Thereafter, the soil purification agent composition was circulated through the model heavy oil-contaminated soil by adjusting the water level difference shown in FIG. 2 so that the flow rate was 1 ml / min (temperature: 25 ° C.). Thereafter, the cleaning waste liquid was collected from the upper outlet of the cylindrical column 21 through the silicon tube 22.
A total of 300 ml of the soil cleaner composition was passed through the column, and then 100 mL of pure water was further passed to rinse the soil cleaner composition. After the end of the flow of pure water, the washed soil was collected from the column in a petri dish and air-dried at room temperature. Residual heavy oil was extracted from the soil with 150 ml of hexane using HORIBA, Ltd. Fat Extractor B-811 type for 2 hours. The hexane component was heated and evaporated from the hexane layer after Soxhlet extraction, and the weight of the oil component (X (g)) extracted as the residue was measured. The soil heavy oil contamination rate (mass%) of the washed soil was calculated as follows.
Soil weight Y (g) = 50 × (100−8) / 100 = 46 in model heavy oil contaminated soil
Soil heavy oil contamination rate (mass%) = X / (46 + X) × 100
The soil heavy oil contamination rate was measured for the washed soil obtained by conducting the washing test on model heavy oil contaminated soils of A heavy oil and C heavy oil, and the detergency was evaluated based on the measured values (Table 4-6 A heavy oil detergency and C heavy oil washability).
−通液性評価−
前記洗浄性評価の試験の際に、土壌浄化剤組成物を流速１ｍｌ／ｍｉｎ（温度２５℃）で通液させるために要した水位差（ｃｍ）を測定した。なお、水位差が小さい程、通液性に優れた土壌浄化剤組成物であるということができる。
-Liquid permeability evaluation-
During the test for evaluating the detergency, the water level difference (cm) required for passing the soil purifier composition at a flow rate of 1 ml / min (temperature 25 ° C.) was measured. In addition, it can be said that it is a soil purifier composition excellent in liquid permeability, so that a water level difference is small.
＜ミセルサイズの測定＞
ミセルサイズの測定は、動的光散乱光度計ＤＬＳ８０００（大塚電子製）を用いて、土壌浄化洗浄剤の流体力学的半径Ｒｈを測定した。測定条件は、サンプル１質量％水溶液に調製し、光源はアルゴンレーザー（４８８ｎｍ）を使用した。
<Measurement of micelle size>
The micelle size was measured by measuring the hydrodynamic radius Rh of the soil cleaning detergent using a dynamic light scattering photometer DLS8000 (manufactured by Otsuka Electronics). Measurement conditions were prepared in a 1% by mass aqueous solution of the sample, and an argon laser (488 nm) was used as the light source.
