摘要： PROBLEM TO BE SOLVED: To provide a biological cleaning method and an apparatus for contaminated soil capable of controlling ventilation according as degradation activity of microorganisms. SOLUTION: An oxygen analyzer 5 is disposed in the contaminated soil S and a decrease rate (δ[O 2 ]/δt) of residual oxygen concentration [O 2 ] is measured by using the oxygen analyzer 5. The contaminated soil S is cleaned while the ventilation volume into the contaminated soil S is controlled in accordance with the decrease rate (δ[O 2 ]/δt). The oxygen consumption C 02 in the contaminated soil S is calculated from the decrease rate (δ[O 2 ]/δt) of residual oxygen concentration [O 2 ] and the soil air volume VSPACE of the contaminated soil S and the ventilation volume into the contaminated soil S is controlled in accordance with the oxygen consumption C 02 . Further preferably, a thermometer 6 is disposed in the contaminated soil S and a soil temperature TSOIL is measured by using the thermometer 6. The ventilation into the contaminated soil is then controlled in accordance with the oxygen consumption C 02 and the soil temperature TSOIL. The ventilation volume is preferably controlled by each of respective areas by disposing the oxygen analyzers 5 and/or the thermometers 6 into a plurality of the areas of the contaminated soil S.

摘要： PROBLEM TO BE SOLVED: To provide an instrument for measuring the gas present in the ground surface layer, so well-designed not to be a large-scale framework as even to allow the easy setup, transport and move because of being, as a whole, constructed mainly of a metal pole, also to allow the instrument itself having a built-in gas detecting element to be disposed to the pole above the ground, separated away from the measurement location, wherein a gas suction pipe having a gas suction port at the end edge thereof be only inserted into the ground, to thereby sufficiently serve the purpose thereof without worry about such cloggings or the like even to thereby simplify a maintenance service job, and, further, to make it possible to measure the object without difficulty even as deep as one meter down in the soil. SOLUTION: The gas measuring instrument 11 being accommodated in a case 10 receiving it is disposed atop the metal pole 8, and the gas suction pipe 15 having the gas suction port 16 at the end edge thereof is protruded out of the lower part of the pole 8, then being allowed to pass integrally through the pole 8 and to be connected to the instrument 11, and an insertion-preventing member 13 of a larger diameter than that of a hole 21 to be made in the ground is also arranged t the outer periphery of the lower part of the pole 8.

摘要： PROBLEM TO BE SOLVED: To make rapidly examinable an extensive polluted site in a labor- saving manner by traveling the ground surface of the polluted site in an unmanned manner and automatically detecting gases evolved from the soil while moving. SOLUTION: A gas detector body part 13 is provided on a remote-controlled vehicle 8. The vehicle 8 has a remote-controlled operation controlling part 11 and self-traveling power other than internal combustion engine power. The body part 13 is data-linked to a personal computer 14 for storing measured data, a gas analysis data storing/processing means. A gas suction part 18 connected to the body part 13 is mounted near the ground side of the vehicle 8.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for decontaminating soil by separat ing a contaminant from the contaminated soil by a water-insoluble organic substance such as an oil and the like. SOLUTION: The soil (D) contaminated by the water-insoluble organic substance, water, an alkalizing agent (A) and an oxidizing agent (O) are thrown into a separation tank (4) and the water-insoluble organic substance is made to the state that it is separated from the soil or it is easily separated from the soil. The water-insoluble organic substance is floated up on a water surface by bubbles fed into the separation tank (4) or bubbles generated in the separation tank (4).
