本発明は、活性炭マット及び炭化水素で汚染された土壌の浄化方法に関する。   The present invention relates to a method for purifying soil contaminated with activated carbon mats and hydrocarbons.

活性炭を用いて消臭することや、炭化水素分解能を有する微生物を用いて炭化水素で汚染された土壌等を浄化することは、従来より知られている。   It is conventionally known to deodorize using activated carbon or to purify soil contaminated with hydrocarbons using microorganisms having hydrocarbon decomposability.

しかしながら、活性炭は、ニオイ成分を吸着することはできるが、分解することができず、そのため、飽和してしまうと、それ以上の消臭効果を得られなくなってしまうという問題がある。   However, activated carbon can adsorb odor components, but cannot decompose it. Therefore, when it is saturated, there is a problem that a further deodorizing effect cannot be obtained.

本発明は、上記のような問題点に鑑み、活性炭による消臭効果を効果的に延ばすことができ、しかも、それを簡素な構造で容易に実現することができる、活性炭マット等を提供することを課題とする。   In view of the above problems, the present invention provides an activated carbon mat or the like that can effectively extend the deodorizing effect of activated carbon and that can be easily realized with a simple structure. Is an issue.

上記の課題は、通気性を有する袋に活性炭が詰められると共に、袋内と袋外とを連絡する揚水布が設けられ、袋外から前記揚水布を通じて袋内の活性炭に、炭化水素分解能を有する微生物を供給することができるようになされていることを特徴とする活性炭マットによって解決される（第１発明）。   The above-mentioned problem is that activated carbon is packed in a breathable bag, a pumping cloth is provided to connect the inside and outside of the bag, and the activated carbon in the bag has hydrocarbon resolution through the pumping cloth from outside the bag. This is solved by an activated carbon mat characterized by being able to supply microorganisms (first invention).

このマットでは、通気性を有する袋を通じて袋内の活性炭に吸着されたニオイ成分は、該活性炭に供給された微生物によって分解されていき、それによって、袋内の活性炭がニオイ成分の吸着によって飽和するのを防がれ、活性炭による消臭効果を効果的に延ばすことができる。   In this mat, the odor component adsorbed to the activated carbon in the bag through the breathable bag is decomposed by the microorganisms supplied to the activated carbon, thereby saturating the activated carbon in the bag by adsorption of the odor component. Can be prevented and the deodorizing effect by activated carbon can be effectively extended.

しかも、袋内の活性炭に対する微生物の供給は、袋内と袋外とを連絡する揚水布を利用して、袋外から行うことができるので、袋内の活性炭に対する微生物の供給を容易に行うことができると共に、微生物による炭化水素の分解に必要な水や栄養分の供給も揚水布を通じて容易に行うことができる。   In addition, the supply of microorganisms to the activated carbon in the bag can be performed from the outside of the bag using a pumping cloth that connects the inside of the bag and the outside of the bag. Therefore, the supply of microorganisms to the activated carbon in the bag can be easily performed. In addition, water and nutrients necessary for the decomposition of hydrocarbons by microorganisms can be easily supplied through the pumping cloth.

加えて、マットに対して揚水布を袋内と袋外とを連絡するように設けるだけでよいので、袋内の活性炭に対する微生物の供給を簡素な構造で行うことができる。   In addition, since it is only necessary to provide the mating cloth so that the inside of the bag communicates with the outside of the bag with respect to the mat, the microorganisms can be supplied to the activated carbon in the bag with a simple structure.

第１発明において、前記袋の内外にパイプが延ばされ、該パイプによって、
該袋内の空気を吸い込んで袋外の空気を袋を通じて袋内に導入させること、及び／又は、該袋内に空気を吐き出して袋内の空気を袋を通じて袋外に排出させること、ができるようになされているとよい（第２発明）。 In the first invention, a pipe is extended inside and outside the bag,
Air inside the bag can be sucked and air outside the bag can be introduced into the bag through the bag, and / or air can be discharged into the bag and the air inside the bag can be discharged out of the bag through the bag. (2nd invention).

この場合は、パイプによって、袋内の空気を吸い込んで袋外の空気を袋を通じて袋内に導入させること、及び／又は、該袋内に空気を吐き出して袋内の空気を袋を通じて袋外に排出させること、を行うことにより、酸素が袋内に積極的に導入され、微生物による炭化水素分解能力が高められ、活性炭に促進的に吸着されていくニオイ成分を促進的に分解していくことができて、消臭効果を高いものにすることができながら、そのような高い消臭効果を効果的に延ばすことができる。特に、パイプによって、袋内の空気を吸い込んで袋外の空気を袋を通じて袋内に導入させる場合は、袋外の空気が袋内に積極的に導入され、袋外の空気に含まれていたニオイ成分を袋内の活性炭に促進的に吸着させていくことができる。   In this case, the air in the bag is sucked by the pipe and the air outside the bag is introduced into the bag through the bag, and / or the air is discharged into the bag and the air in the bag is taken out of the bag through the bag. By exhausting, oxygen is actively introduced into the bag, the ability of microorganisms to decompose hydrocarbons is enhanced, and the odor components that are adsorbed by activated carbon are promoted to be decomposed. It is possible to increase the deodorizing effect while effectively increasing the deodorizing effect. In particular, when the air inside the bag is sucked in by the pipe and the air outside the bag is introduced into the bag through the bag, the air outside the bag is actively introduced into the bag and included in the air outside the bag. The odor component can be adsorbed on activated carbon in the bag in an accelerated manner.

第２発明において、前記パイプから袋内に向けて光照射をすることができるようになされているとよい（第３発明）。この場合は、袋内の活性炭に繁殖した微生物に光照射がなされることで炭化水素の分解能力が高められ、しかも、それを、上記のような酸素供給パイプを利用して簡素な構造で実現することができる。   In the second invention, it is preferable that light can be irradiated from the pipe into the bag (third invention). In this case, the ability to decompose hydrocarbons is enhanced by irradiating the microorganisms that propagated on the activated carbon in the bag with light, and this is achieved with a simple structure using the oxygen supply pipe as described above. can do.

また、本発明は、第１〜第３発明のいずれかの活性炭マットであって、炭化水素分解能を有する微生物を揚水布を通じて袋内の活性炭に供給したものを、炭化水素で汚染された土壌に設置し、土壌に含まれる炭化水素を袋内の活性炭に吸着させることを特徴とする、炭化水素で汚染された土壌の浄化方法を含む（第４発明）。   Further, the present invention is the activated carbon mat according to any one of the first to third inventions, wherein a microorganism having hydrocarbon decomposability is supplied to activated carbon in a bag through a pumping cloth, and the soil contaminated with hydrocarbon It includes a method for purifying soil contaminated with hydrocarbons, characterized in that the hydrocarbons contained in the soil are adsorbed onto the activated carbon in the bag (fourth invention).

この方法では、土壌に含まれる炭化水素を活性炭が吸着し、吸着した炭化水素を微生物が分解して、炭化水素で汚染された土壌を効果的に消臭、清浄化していくことができる。袋の内外にパイプが延ばされ、該パイプによって、該袋内の空気を吸い込んで袋外の空気を袋を通じて袋内に導入させること、及び／又は、該袋内に空気を吐き出して袋内の空気を袋を通じて袋外に排出させること、ができるようになされている場合は、微生物による炭化水素分解能力を高めることなどが可能になる。該パイプから袋内に向けて光照射をすることができるようになされている場合は、袋内の活性炭に繁殖した微生物に光照射をして炭化水素の分解能力を高めることができる。   In this method, activated carbon adsorbs hydrocarbons contained in soil, microorganisms decompose the adsorbed hydrocarbons, and the soil contaminated with hydrocarbons can be effectively deodorized and cleaned. A pipe is extended into and out of the bag, and the pipe sucks air inside the bag and introduces air outside the bag through the bag into the bag and / or discharges air into the bag and into the bag. If the air can be discharged out of the bag through the bag, the ability to decompose hydrocarbons by microorganisms can be increased. In the case where light can be irradiated from the pipe into the bag, the microorganisms propagated on the activated carbon in the bag can be irradiated with light to enhance the ability to decompose hydrocarbons.

本発明の活性炭マットは、以上のとおりのものであるから、活性炭による消臭効果を効果的に延ばすことができ、しかも、それを簡素な構造で容易に実現することができる。   Since the activated carbon mat of the present invention is as described above, the deodorizing effect by the activated carbon can be effectively extended, and it can be easily realized with a simple structure.

また、本発明の、炭化水素で汚染された土壌の浄化方法によれば、土壌に含まれる炭化水素を活性炭が吸着し、吸着した炭化水素を微生物が分解して、炭化水素で汚染された土壌を効果的に消臭、清浄化していくことができ、しかも、それを簡素な構造で容易に実現することができる。   Further, according to the method for purifying soil contaminated with hydrocarbons of the present invention, activated carbon adsorbs hydrocarbons contained in the soil, microorganisms decompose the adsorbed hydrocarbons, soil contaminated with hydrocarbons Can be effectively deodorized and cleaned, and can be easily realized with a simple structure.

(C) is a plan view in which a bag is seen through, and FIG. 図（イ）及び図（ロ）はそれぞれ、油で汚染された土壌を活性炭マットを用いて清浄化する方法を示す断面正面図である。FIGS. 1A and 1B are cross-sectional front views showing a method of cleaning soil contaminated with oil using an activated carbon mat. 油で汚染された土壌を活性炭マットを用いて清浄化する他の方法を示す断面正面図である。It is a cross-sectional front view which shows the other method of cleaning the soil contaminated with oil using the activated carbon mat.

次に、本発明の実施形態を図面に基づいて説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１に示す実施形態の活性炭マット１は、不織布などからなる通気性を有する袋２内に活性炭３が詰められた偏平な方形状のマットからなっていて、袋２内の幅方向の中央部には、パイプとしての吸引パイプ４が通されており、その端部は袋２の外に導出されている。吸引パイプ４の周壁には、袋２内に存在する部分において、多数の孔４ａ…が分散状態に設けられ、該吸引パイプ４の袋外導出部分に吸引機５を接続して吸引することにより、袋２内の空気が吸引パイプ４の周壁の孔４ａ…を通じて吸い込まれ、袋２の外の空気が通気性の袋２を通じて袋２内に導入されるようになされている。   An activated carbon mat 1 according to the embodiment shown in FIG. 1 is formed of a flat rectangular mat in which activated carbon 3 is packed in a bag 2 having air permeability made of a nonwoven fabric or the like. A suction pipe 4 as a pipe is passed through, and an end portion thereof is led out of the bag 2. The peripheral wall of the suction pipe 4 is provided with a large number of holes 4a in a dispersed state in a portion existing in the bag 2, and a suction machine 5 is connected to the lead-out portion of the suction pipe 4 outside the bag for suction. The air in the bag 2 is sucked through the holes 4a in the peripheral wall of the suction pipe 4, and the air outside the bag 2 is introduced into the bag 2 through the breathable bag 2.

そして、袋２内において、吸引パイプ４を挟んだ幅方向の両側には、揚水布６，６が、活性炭３の厚さ方向の中間部を通るように配置されており、各揚水布６，６は、袋２の外に導出されて袋２の内と外とを連絡するようになされており、袋２の外に導出されている部分に、炭化水素分解能を有する微生物１２を供給することで、該微生物１２は、揚水布６，６を通じて袋２内に送り込まれ、袋２内の活性炭３に供給されるようになされている。この微生物１２による炭化水素の分解に必要な水１３や栄養剤１４も揚水布６，６を通じて活性炭３の側に供給することができるのはいうまでもない。   And in the bag 2, the pumping cloth 6 and 6 is arrange | positioned so that it may pass through the intermediate part of the thickness direction of the activated carbon 3 on both sides of the width direction on both sides of the suction pipe 4, and each pumping cloth 6, 6 is led out of the bag 2 so as to communicate the inside and outside of the bag 2, and the microorganism 12 having hydrocarbon decomposability is supplied to the part led out of the bag 2. The microorganism 12 is fed into the bag 2 through the pumping cloths 6 and 6 and supplied to the activated carbon 3 in the bag 2. Needless to say, water 13 and nutrients 14 necessary for the decomposition of hydrocarbons by the microorganism 12 can also be supplied to the activated carbon 3 through the pumping cloths 6 and 6.

更に、吸引パイプ４から袋２内に向けて光照射がなされるようになっている。光は、吸引パイプ４の孔４ａ…を通じて袋２内に照射されるようになされていてもよいし、吸引パイプ４として透明パイプを用いて袋２内に照射されるようになされていてもよい。光照射のための光源７は、ＬＥＤ等からなって、吸引パイプ４内に挿入して光照射を行うようにしてもよいし、吸引パイプ４内を光路にして袋の外から光を送るようにしてもよい。   Furthermore, light irradiation is performed from the suction pipe 4 into the bag 2. The light may be irradiated into the bag 2 through the holes 4a ... of the suction pipe 4, or may be irradiated into the bag 2 using a transparent pipe as the suction pipe 4. . The light source 7 for light irradiation may be an LED or the like and may be inserted into the suction pipe 4 for light irradiation, or light may be sent from outside the bag with the inside of the suction pipe 4 as an optical path. It may be.

上記の活性炭マット１では、通気性を有する袋２を通じて袋２内の活性炭３に吸着されたニオイ成分は、該活性炭３に供給された微生物１２によって分解されていき、それによって、袋２内の活性炭３がニオイ成分の吸着によって飽和するのを防がれ、活性炭３による消臭効果を効果的に延ばすことができる。   In the activated carbon mat 1, the odor component adsorbed on the activated carbon 3 in the bag 2 through the air-permeable bag 2 is decomposed by the microorganisms 12 supplied to the activated carbon 3. The activated carbon 3 is prevented from being saturated by the adsorption of the odor component, and the deodorizing effect by the activated carbon 3 can be effectively extended.

しかも、袋２内の活性炭３に対する微生物１２の供給は、揚水布６を利用して、袋２の外から行うことができるので、袋２内の活性炭３に対する微生物１２の供給を容易に行うことができると共に、微生物１２による炭化水素の分解に必要な水や栄養分の供給も揚水布６を通じて容易に行うことができる。加えて、マット１に対して揚水布６を袋２の内外を連絡するように設けるだけでよいので、袋２内の活性炭３に対する微生物１２の供給を簡素な構造で行うことができる。   Moreover, since the microorganisms 12 can be supplied to the activated carbon 3 in the bag 2 from the outside of the bag 2 using the pumping cloth 6, the microorganisms 12 can be easily supplied to the activated carbon 3 in the bag 2. In addition, water and nutrients necessary for the decomposition of the hydrocarbons by the microorganism 12 can be easily supplied through the pumping cloth 6. In addition, the pumping cloth 6 need only be provided so as to communicate the inside and outside of the bag 2 with the mat 1, so that the microorganisms 12 can be supplied to the activated carbon 3 in the bag 2 with a simple structure.

また、吸引パイプ４に吸引機５を接続して、吸引機５を駆動すれば、吸引パイプ４に袋２内の空気が吸い込まれ、それにより、袋２の外の空気が袋２を通じて袋２内に積極的に導入され、袋２の外の空気に含まれていたニオイ成分を袋２内の活性炭３に促進的に吸着させていくことができ、しかも、袋２の外の空気が袋２内に積極的に導入されることで、微生物１２による炭化水素分解能力が高められ、活性炭３に促進的に吸着されていくニオイ成分を促進的に分解していくことができて、消臭効果を高いものにすることができながら、そのような高い消臭効果を効果的に延ばすことができる。   Further, if the suction machine 5 is connected to the suction pipe 4 and the suction machine 5 is driven, the air in the bag 2 is sucked into the suction pipe 4, whereby the air outside the bag 2 passes through the bag 2. The odor component that is actively introduced into the bag 2 and contained in the air outside the bag 2 can be adsorbed to the activated carbon 3 in the bag 2 in an accelerated manner, and the air outside the bag 2 By being actively introduced into the inside, the ability of the microorganisms 12 to decompose hydrocarbons is enhanced, and the odorous components adsorbed on the activated carbon 3 can be promoted to be decomposed and deodorized. While the effect can be increased, such a high deodorizing effect can be effectively extended.

更に、吸引パイプ４から袋２内に向けて光照射をすることができるようになされているので、袋２内の活性炭３に繁殖した微生物１２の炭化水素の分解能力を光照射によって高めることができる。   Further, since light can be irradiated from the suction pipe 4 into the bag 2, the ability to decompose hydrocarbons of the microorganisms 12 propagated on the activated carbon 3 in the bag 2 can be enhanced by light irradiation. it can.

上記の活性炭マット１は、例えば、重油などの油で汚染された土壌を清浄化するのに用いることができる。即ち、図２（イ）に示す例は、油で汚染された土壌８を掘削した後、その掘削穴９を囲む土壌面に活性炭マット１を、揚水布６と吸引パイプ４とが地上に残されるように敷き、しかる後、掘削穴９を、汚染されていない清浄土１０で埋めたものである。炭化水素分解能を有する微生物１２、例えば油分解菌は、埋込み前の活性炭マット１の活性炭３に揚水布６を通じて予め供給しておいてもよいし、埋込み後の活性炭マット１の活性炭３に揚水布６を通じて供給するというようにしてもよい。   The activated carbon mat 1 can be used to clean soil contaminated with oil such as heavy oil. That is, in the example shown in FIG. 2A, after excavating the soil 8 contaminated with oil, the activated carbon mat 1 is left on the soil surface surrounding the excavation hole 9, and the pumping cloth 6 and the suction pipe 4 remain on the ground. Then, the excavation hole 9 is filled with uncontaminated clean soil 10. Microorganisms 12 having hydrocarbon decomposability, such as oil-degrading bacteria, may be supplied in advance to the activated carbon 3 of the activated carbon mat 1 before embedding through the pumping cloth 6, or the activated carbon 3 of the activated carbon mat 1 after embedding. 6 may be supplied.

これにより、土壌８に含まれている重油のニオイ成分をマット１内の活性炭３が吸着し、吸着したニオイ成分を微生物１２が分解し、重油で汚染された土壌８は効果的に消臭され清浄化されていく。   As a result, the activated carbon 3 in the mat 1 adsorbs the odor component of the heavy oil contained in the soil 8, the microorganism 12 decomposes the adsorbed odor component, and the soil 8 contaminated with the heavy oil is effectively deodorized. It will be cleaned.

その際に、吸引パイプ４に吸引機５を接続して空気の吸引を行えば、袋２内の空気が吸引パイプ４に吸い込まれていき、それにより、袋２外から空気が袋２内に積極的に導入されて、油によるニオイ成分は袋２内の活性炭３に促進的に吸着されていくと共に、微生物１２によるニオイ成分の分解能力も高められて、油で汚染された土壌８を効果的に消臭、清浄化していくことができる。   At that time, if the suction machine 5 is connected to the suction pipe 4 and the air is sucked, the air in the bag 2 is sucked into the suction pipe 4, so that the air enters the bag 2 from the outside of the bag 2. Actively introduced, the odor component due to oil is adsorbed to the activated carbon 3 in the bag 2 at the same time, and the ability to decompose the odor component by the microorganisms 12 is enhanced, so that the soil 8 contaminated with oil is effective. Can be deodorized and cleaned.

なお、パイプ４は、空気吐出機を接続することで袋２内に空気を吐出することができるようになされていてもよく、その場合は、袋２内に積極的に空気が吐き出されて微生物１２によるニオイ成分の分解能力が高められ、油で汚染された土壌８を効果的に消臭、清浄化していくことができる。また、パイプ４は、袋２内の空気を吸引することと、袋２内に空気を吐出することとの両方をできるようになされて、選択的に、袋２内の空気を吸引したり、袋２内に空気を吐出したりすることができるようになされていてもよい。   The pipe 4 may be configured to be able to discharge air into the bag 2 by connecting an air discharge machine. In that case, air is actively discharged into the bag 2 and microorganisms are discharged. The ability to decompose odor components by 12 can be enhanced, and the soil 8 contaminated with oil can be effectively deodorized and cleaned. Further, the pipe 4 is configured to be capable of both sucking the air in the bag 2 and discharging the air into the bag 2, and selectively sucking the air in the bag 2, The air may be discharged into the bag 2.

また、地上から水と栄養剤を揚水布６を通じてもマット１内の微生物１２に供給すると共に、吸引パイプ４から袋２内に向けて光照射をすることにより、袋２内の活性炭３に繁殖した微生物１２の分解能力を高めることができて、油で汚染された土壌８を効果的に清浄化していくことができる。１１は建物の基礎である。   In addition, water and nutrients are supplied from the ground to the microorganisms 12 in the mat 1 through the pumping cloth 6, and light is irradiated from the suction pipe 4 into the bag 2 to propagate on the activated carbon 3 in the bag 2. Thus, the ability of decomposing the microorganisms 12 can be increased, and the soil 8 contaminated with oil can be effectively cleaned. 11 is the foundation of the building.

図２（ロ）に示す例は、油で汚染された土壌８の地表面部に活性炭マット１を敷いたものであり、同様に、油で汚染された土壌８を効果的に消臭、清浄化していくことができる。   In the example shown in FIG. 2 (b), activated carbon mat 1 is laid on the ground surface portion of soil 8 contaminated with oil. Similarly, soil 8 contaminated with oil is effectively deodorized and cleaned. Can be made.

図３に示す例は、油で汚染された土壌８を掘削し、掘削穴９に対して、揚水布６と、掘削した油汚染土８とを上方に向けて交互配置となるように多層に埋め戻していき、最上部に活性炭マット１を敷設したもので、各層に配置した揚水布６…の端は、地上に導出されており、その導出部分を通じて、炭化水素分解能を有する微生物１２と、その栄養剤、水が、油汚染土８中に多層状態に供給されるようになされている。このような構造ないし方法によれば、最上部に活性炭マット１による消臭、清浄化のみならず、油汚染土８中をも効果的に消臭、清浄化していくことができる。   In the example shown in FIG. 3, the soil 8 contaminated with oil is excavated, and the pumping cloth 6 and the excavated oil-contaminated soil 8 are arranged in multiple layers so that the excavated oil-contaminated soil 8 is directed upward with respect to the excavation hole 9. The activated carbon mat 1 is laid back at the top, and the ends of the pumping cloth 6 arranged in each layer are led out to the ground, and through the lead-out part, the microorganisms 12 having hydrocarbon resolution, The nutrient and water are supplied in a multilayer state in the oil-contaminated soil 8. According to such a structure or method, not only deodorization and cleaning by the activated carbon mat 1 at the top, but also the oil-contaminated soil 8 can be effectively deodorized and cleaned.
