Description
本発明は、土壌用液体洗浄剤組成物及び土壌の洗浄方法に関する。 The present invention relates to a liquid detergent composition for soil and a method for cleaning soil.
近年、産業廃棄物の不法投棄、工場における廃棄物処理、最終処分場からの有害物質漏出事故による土壌汚染そして石油コンビナート、ガソリンスタンドや化学工場などの敷地・跡地では、種々の油類の漏出事故や長期にわたる漏出により、様々な場面で深刻な土壌汚染にみまわれるケースが多発している。 In recent years, illegal dumping of industrial waste, waste treatment at factories, soil contamination due to harmful substance leakage accidents from final disposal sites, and various oil leak accidents at sites and sites such as petroleum complexes, gas stations and chemical factories. Due to long-term leaks and long-term leaks, there are many cases of serious soil contamination in various situations.
従来、このような汚染土壌の修復方法には、掘削後の焼却処理、固化・固定化、囲い込み処理、バイオレメディエーション、土壌洗浄法等の技術が用いられてきたが、中でも汚染物質を土壌から除去し、浄化する技術が主流となりつつある。 Conventionally, as a method for repairing such contaminated soil, techniques such as incineration after excavation, solidification / immobilization, enclosing treatment, bioremediation, and soil cleaning method have been used. Among them, pollutants are removed from the soil. However, purification technology is becoming mainstream.
土壌洗浄法は、他の方法と比較して、異なる汚染種（油、重金属）でも浄化出来るため汎用性が高く、バイオレメディエーション等の前処理工程としても利用でき、汚染土壌の処理量が大きく、総合的に浄化費用の低コスト化を実現できる要素を含んでいる。通常、土壌洗浄法では、界面活性剤などを含有する洗浄剤が用いられる。 Compared to other methods, the soil cleaning method is highly versatile because it can purify different contaminated species (oil, heavy metals), and it can also be used as a pretreatment step for bioremediation, etc., and the amount of contaminated soil treated is large. It includes elements that can reduce the purification cost comprehensively. Usually, in the soil cleaning method, a cleaning agent containing a surfactant or the like is used.
特許文献１には、有機汚染物質による地層内汚染区域に、ノニオン界面活性剤などの界面活性剤とグリコール系溶剤などの溶剤との混合液及び水を注入し地層中に存在する有機汚染物質と混合して、乳化・剥離作用により低粘性の乳化液を生成する工程と、発泡剤を注入して地層内での微発泡作用により混合・乳化を促進する工程を備え、低粘性化した乳化液を地上に吸引し回収する汚染土壌の原位置浄化方法が開示されている。 In Patent Document 1, a mixed solution of a surfactant such as a nonionic surfactant and a solvent such as a glycol-based solvent and water are injected into an area contaminated in the formation by an organic pollutant to form an organic pollutant existing in the formation. A low-viscosity emulsion is provided with a step of mixing to generate a low-viscosity emulsion by emulsification / peeling action and a step of injecting a foaming agent to promote mixing / emulsification by a slight foaming action in the formation. Disclosed is a method for in-situ purification of contaminated soil that is sucked and recovered on the ground.
しかしながら、前記特許文献の方法で具体的に用いられている界面活性剤や溶剤は、引火性に伴う危険性や、洗浄性能が満足できないという問題があった。また、土壌の洗浄に用いられる液体洗浄剤組成物には、均一な外観を有するなど組成物の安定性（以下、一液安定性ともいう）に優れ、また、取り扱いやすい適正な粘度を有することが望まれる。 However, the surfactants and solvents specifically used in the method of the above patent document have problems that there is a danger associated with flammability and the cleaning performance cannot be satisfied. In addition, the liquid detergent composition used for cleaning soil has excellent stability of the composition (hereinafter, also referred to as one-component stability) such as having a uniform appearance, and has an appropriate viscosity that is easy to handle. Is desired.
本発明は、土壌汚染に対する洗浄効果に優れ、引火性が低く、一液安定性（外観）に優れ、粘度が低く、土壌用液体洗浄剤組成物及びこれを用いた土壌の洗浄方法を提供する。 The present invention provides a liquid detergent composition for soil, which has an excellent cleaning effect on soil contamination, low flammability, excellent one-component stability (appearance), and low viscosity, and a soil cleaning method using the same. ..
本発明は、（Ａ）ノニオン界面活性剤〔以下、（Ａ）成分という〕と、（Ｂ）エチレングリコールモノブチルエーテル、エチレングリコールモノイソブチルエーテル、ジエチレングリコールモノブチルエーテル、ジエチレングリコールモノイソブチルエーテル及びトリエチレングリコールモノブチルエーテルから選ばれる１種以上の化合物〔以下、（Ｂ）成分という〕と、（Ｃ）水〔以下、（Ｃ）成分という〕と、を含有する土壌用液体洗浄剤組成物であって、（Ｃ）水の含有量が１５質量％以上８０質量％以下である、土壌用液体洗浄剤組成物に関する。 The present invention comprises (A) a nonionic surfactant [hereinafter referred to as (A) component] and (B) ethylene glycol monobutyl ether, ethylene glycol monoisobutyl ether, diethylene glycol monobutyl ether, diethylene glycol monoisobutyl ether and triethylene glycol monobutyl ether. A liquid cleaning composition for soil containing one or more compounds selected from [hereinafter referred to as (B) component] and (C) water [hereinafter referred to as (C) component], (C). ) The present invention relates to a liquid cleaning agent composition for soil having a water content of 15% by mass or more and 80% by mass or less.
また、本発明は、汚染された土壌を、本発明の土壌用液体洗浄剤組成物で洗浄する、土壌の洗浄方法に関する。 The present invention also relates to a soil cleaning method for cleaning contaminated soil with the soil liquid detergent composition of the present invention.
本発明によれば、土壌汚染に対する洗浄効果に優れ、引火性が低く、一液安定性（外観）に優れ、粘度が低く、土壌用液体洗浄剤組成物及びこれを用いた土壌の洗浄方法が提供される。 According to the present invention, a liquid detergent composition for soil and a soil cleaning method using the same have excellent cleaning effect against soil contamination, low flammability, excellent one-component stability (appearance), and low viscosity. Provided.
本発明が効果を奏するメカニズムは不明であるも次のように考えられる。
（Ｂ）成分はいわゆるグリコール骨格を有する化合物であり、一般的にアルコールに比べて分子量が低い割に融点や粘度が高いという性質を持っている。これにより、（Ｂ）成分を、界面活性剤、例えば（Ａ）成分のノニオン界面活性剤と共に配合した土壌用液体洗浄剤組成物は、アルコール系溶剤を用いて処方した製剤に比べて引火点が高くなる、もしくは（Ｃ）成分の水の配合量により、引火点が検出しなくなり、取扱いが容易となる。
さらに（Ｂ）成分は１つのブチル基ないしイソブチル基を有しているが、これにより（Ｂ）成分が汚染物質である油に溶解しやすくなり、（Ａ）成分による油の乳化や土壌からの脱離が促進され、その結果、洗浄性が向上しているものと推察している。ブチル基以外の基、例えば炭素数のより小さいプロピル基、エチル基、メチル基を有する化合物では、汚染物質である油への溶解が少なく洗浄性への寄与が小さい。またブチル基が２つの化合物やヘキシル基などの炭素数のより大きいアルキル基を有する化合物では、汚染物質である油への溶解は良好となるが、疎水性が強くなり過ぎることから、土壌用洗浄剤の製剤化時に白濁、分離や分層などを起こしてしまうものと考えられる。すなわち、（Ｂ）成分は、（Ａ）成分、（Ｃ）成分と組み合わせた組成物において、単に溶剤として機能するのみではなく、一液安定性や粘度の適正化に加え、土壌の洗浄における洗浄力の向上という予想外の効果をもたらすものである。
Although the mechanism by which the present invention is effective is unknown, it is considered as follows.
The component (B) is a compound having a so-called glycol skeleton, and generally has a property of having a high melting point and viscosity in spite of having a lower molecular weight than alcohol. As a result, the liquid detergent composition for soil in which the component (B) is blended with the surfactant, for example, the nonionic surfactant of the component (A), has a flash point higher than that of the formulation formulated using the alcohol solvent. The flash point becomes undetectable due to the increase in the amount or the amount of water of the component (C), which facilitates handling.
Furthermore, the component (B) has one butyl group or an isobutyl group, which makes it easier for the component (B) to dissolve in the contaminating oil, and the component (A) emulsifies the oil or from the soil. It is presumed that the desorption is promoted, and as a result, the detergency is improved. A compound having a group other than a butyl group, for example, a propyl group having a smaller carbon number, an ethyl group, or a methyl group has less dissolution in oil, which is a contaminating substance, and has a small contribution to detergency. In addition, compounds having an alkyl group having a larger carbon number, such as a compound having two butyl groups or a hexyl group, dissolve well in oil, which is a pollutant, but become too hydrophobic, so that they are used for cleaning soil. It is considered that white turbidity, separation and stratification occur when the agent is formulated. That is, the component (B) not only functions as a solvent in the composition combined with the component (A) and the component (C), but also has one-component stability and optimization of viscosity, as well as cleaning in soil cleaning. It has the unexpected effect of improving power.

本発明の土壌の洗浄方法には、本発明の土壌用液体洗浄剤組成物で述べた事項を適宜適用することができる。
<Soil cleaning method>
The present invention relates to a soil cleaning method for cleaning contaminated soil with the soil liquid detergent composition of the present invention.
The matters described in the liquid detergent composition for soil of the present invention can be appropriately applied to the method for cleaning soil of the present invention.
本発明の土壌の洗浄方法では、汚染された土壌を、前記土壌用液体洗浄剤組成物と水とを混合して得られる洗浄液で洗浄することができる。この場合、汚染された土壌を洗浄する直前に前記洗浄液を調製することができる。 In the soil cleaning method of the present invention, contaminated soil can be washed with a cleaning liquid obtained by mixing the liquid detergent composition for soil and water. In this case, the cleaning solution can be prepared immediately before cleaning the contaminated soil.
本発明の土壌の洗浄方法では、例えば、掘削を行わずに土壌に本発明の組成物又は前記洗浄液を注入して洗浄することができる。本発明では、例えば、本発明の土壌用液体洗浄剤組成物又は前記洗浄液を所定の位置で汚染された土壌に注入し、汚染された土壌中を通過させた後、前記所定の位置とは異なる位置で前記組成物又は前記洗浄液を回収することができる。従って、本発明では、例えば、石油系化合物により汚染された土壌に対して、掘削することなく所定の位置で本発明の組成物又は前記洗浄液を注入し、土壌中を通過する前記組成物又は前記洗浄液に石油系化合物を取り込み、前記所定の位置とは異なる位置で前記組成物又は前記洗浄液を回収することができる。本発明では、回収した前記組成物又は前記洗浄液から石油系化合物などの汚染物質を分離することができる。前記組成物又は前記洗浄液の回収は、揚水法などで行うことができ、具体的には汲み上げポンプなどの汲み上げ手段により行うことができる。また、特開２００５－２７９４２３号公報の方法では、発泡剤を注入する工程を備えているが、本発明の土壌の洗浄方法では、発泡剤を注入しなくても優れた洗浄効果が得られる。本発明の土壌の洗浄方法は、発泡剤、例えば重曹を含む発泡剤、更に重曹と酢酸とを組み合わせた発泡剤を用いない洗浄方法であってよい。 In the soil cleaning method of the present invention, for example, the composition of the present invention or the cleaning liquid can be injected into the soil for cleaning without excavation. In the present invention, for example, the liquid detergent composition for soil of the present invention or the cleaning liquid is injected into the contaminated soil at a predetermined position and passed through the contaminated soil, and then the position is different from the predetermined position. The composition or the cleaning solution can be recovered at the position. Therefore, in the present invention, for example, the composition of the present invention or the cleaning liquid is injected into the soil contaminated with a petroleum compound at a predetermined position without excavation, and the composition or the above-mentioned composition passes through the soil. The petroleum-based compound can be incorporated into the cleaning liquid, and the composition or the cleaning liquid can be recovered at a position different from the predetermined position. In the present invention, pollutants such as petroleum compounds can be separated from the recovered composition or the cleaning liquid. The composition or the cleaning liquid can be recovered by a pumping method or the like, and specifically, by a pumping means such as a pumping pump. Further, although the method of JP-A-2005-279423 includes a step of injecting a foaming agent, the soil cleaning method of the present invention can obtain an excellent cleaning effect without injecting a foaming agent. The soil cleaning method of the present invention may be a cleaning method that does not use a foaming agent, for example, a foaming agent containing baking soda, or a foaming agent in which baking soda and acetic acid are combined.
また、本発明の土壌の洗浄方法では、例えば、掘削土壌を対象として洗浄することができる。従って、本発明により、本発明の組成物又は前記洗浄液で、石油系化合物により汚染された掘削土壌を用いて洗浄する、掘削土壌の洗浄方法が提供される。本発明の掘削土壌の洗浄方法では、洗浄した掘削土壌のすすぎは行ってもよいし、行わなくてもよい。工程の簡略化などの観点では、本発明では、すすぎ工程を実施しなくてもよい。洗浄後の掘削土壌は、採取した場所や別の場所に埋め戻して再利用することができる。 Further, in the soil cleaning method of the present invention, for example, excavated soil can be cleaned. Therefore, the present invention provides a method for cleaning excavated soil by using the composition of the present invention or the cleaning solution for excavated soil contaminated with a petroleum-based compound. In the method for cleaning excavated soil of the present invention, the washed excavated soil may or may not be rinsed. From the viewpoint of simplifying the process, it is not necessary to carry out the rinsing process in the present invention. The excavated soil after cleaning can be reused by backfilling it in the place where it was collected or in another place.
本発で用いる前記洗浄液は、ｐＨ６以上８以下であってよい。また、本発明で用いる前記洗浄液における（Ａ）成分の含有量は、例えば０．１質量％以上、更に０．２質量％以上、そして、５質量％以下、更に２質量％以下であってよい。本発明の土壌の洗浄方法に用いる本発明の組成物も、ｐＨや（Ａ）成分の含有量が前記の範囲であってよい。 The cleaning solution used in this engine may have a pH of 6 or more and 8 or less. Further, the content of the component (A) in the cleaning liquid used in the present invention may be, for example, 0.1% by mass or more, further 0.2% by mass or more, and 5% by mass or less, further 2% by mass or less. ..

(3-4) Evaluation of detergency 1. After the injection of the washing liquid was completed in (3-3), 10.0 g of soil was weighed in a 100 ml screw tube and placed in a constant temperature bath at 40 ° C. for 15 hours without a lid. In parallel, about 3 g of the soil after the injection was precisely weighed and placed in a constant temperature bath at 105 ° C. for 15 hours, and the dry clay content of the soil after the injection was measured.
2. 2. After 15 hours, about 50 g of anhydrous sodium sulfate was added to the screw tube and shaken.
3. 3. Further, 50 ml of dichloromethane was added to the screw tube, the mixture was stirred with a pencil mixer for 1 minute, and allowed to stand for 60 minutes.
4. The supernatant after allowing to stand was transferred to a 100 ml volumetric flask, 30 ml of dichloromethane was further added, and the mixture was stirred with a pencil mixer for 1 minute and allowed to stand for 60 minutes.
5. 4. The supernatant was transferred to another 100 ml volumetric flask, 30 ml of dichloromethane was further added, the mixture was stirred with a pencil mixer for 1 minute, and the mixture was allowed to stand for 60 minutes.
6. 5. The supernatant after standing still was transferred to another 100 ml volumetric flask, and the solution was made up to 100 ml with dichloromethane to prepare a dichloromethane extract.
7. The dichloromethane extract was filtered through a 0.45 μm filter, and then the gas oil content was quantified by 6850A gas chromatography manufactured by Agilent Technologies.
8. The quantification result was converted into the amount contained in the dry clay content (dried at 105 ° C.) in the soil after the injection, and used as the residual light oil amount. In the table, the amount of light oil mg per 1 kg of soil is shown as TPH (mg / kg). If the appearance of the liquid detergent composition for soil is not transparent, the cleaning test was not performed because the results of the cleaning property vary widely.
＊１ 比較例３－２ａは、３回洗浄性の評価を行い、その最大値と最小値を示した。比較例３－２ａは、最大値と最小値の誤差が、１５％程度（最小値／最大値で算出）ないし１８％程度（最大値／最小値で算出）であった。なお、実施例で洗浄性を複数回、例えば３回洗浄性評価した場合の誤差は比較例よりも小さいものとなる。例えば、実施例３－２ａは、更に同じ条件で２回洗浄性評価（表に示した評価との合計で３回の洗浄性評価となる）を行ったところ、ＴＰＨは、１６９０ｍｇ／ｋｇと１６７６ｍｇ／ｋｇであった。これらを最大値と最小値として、比較例３－２ａと同様に誤差を算出すると、最大値と最小値のどちらを分母にしても、０．８％程度であり、比較例３－２ａと比べて、誤差が非常に小さかった。なお、実施例３－２ａの、表に示した１回目の測定値は１６８９ｍｇ／ｋｇであり、本例の前記最大値と最小値の範囲に収まっている。 * 1 In Comparative Example 3-2a, the detergency was evaluated three times, and the maximum value and the minimum value were shown. In Comparative Example 3-2a, the error between the maximum value and the minimum value was about 15% (calculated by the minimum value / maximum value) to about 18% (calculated by the maximum value / minimum value). In addition, the error when the detergency is evaluated a plurality of times, for example, three times in the examples is smaller than that in the comparative example. For example, in Example 3-2a, the detergency evaluation was further performed twice under the same conditions (the total of the evaluations shown in the table is three detergency evaluations), and the TPH was 1690 mg / kg and 1676 mg. It was / kg. When the error is calculated in the same manner as in Comparative Example 3-2a with these as the maximum value and the minimum value, it is about 0.8% regardless of which of the maximum value and the minimum value is the denominator, which is compared with Comparative Example 3-2a. The error was very small. The first measured value shown in the table of Example 3-2a was 1689 mg / kg, which was within the range of the maximum value and the minimum value of this example.
