    • PROBLEM TO BE SOLVED: To provide a board-shaped vessel for photosynthesis reaction able to be supported at various angles including the vertical. SOLUTION: A photosynthesis reaction vessel 2 is formed by tightly closing both the opening ends of a board-shaped tube 3 having transparent circumference walls with a pair of lids 5. Photosynthesis microorganisms and water are placed in the reaction vessel 2, and the microorganisms and water receive light through the circumference walls. The reaction vessel 2 is fixed on a supporting body W by a fixing means 6. Entrances 16a, 16b are formed on the lid 5, and they enable the exchanging of the water and/or the microorganisms in the reaction vessel 2. A heat transferable partition wall 25b setting apart the outer layer 23 at the atmospheric side from the inner layer 24 at the supporting body side is formed in the reaction vessel 2, and outer layer entrances 16a, 16b, 19a, 19b and inner layer entrances 40a, 40b each separately communicating with the outer layer 23 and with the inner layer 24 are formed on the lid 5. In either 23 (or 24) of the outer layer 23 and the inner layer 24, the photosynthesis microorganisms and water are placed, and a heating medium is introduced into the other layer 24 (or 23). Thus, the temperature of the water in the former layer 23 (or 24) is controlled. In the former layer 23 (or 24), a mixing means 9 is placed.

    • 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.

    • PROBLEM TO BE SOLVED: To provide a cleaning method and device which are capable of uniformly supplying nutrient materials, oxygen and moisture to the entire part of contaminated soil. SOLUTION: The contaminated soil 1 is fed into a contaminated soil cleaning vessel 10 and washing water 4 in which the nutrient materials of contaminant degradation bacteria are included is injected into the cleaning vessel 10 by an injector 21, by which the contaminated soil 1 is submerged. The contaminants 2 having the specific gravity smaller than the specific gravity of the washing water 4 are separated from the surface of the washing water 4 and the washing water 4 is made to flow out by a draining device 27 after the separation of the contaminants 2 and the air is admitted into the contaminated soil 1. The contaminants 2 in the contaminated soil 1 are degraded by the degradation bacterial in the presence of the advancing air and the injected nutrient materials, by which the contaminated soil 1 is cleaned. More preferably, the process from the injection of the washing water 4 to the outflow is iterated according to the decrease of the advancing air or the injected nutrient materials.

    • PURPOSE:To prevent clogging of cord-like carriers and the carrier units thereof by installing the carrier units consisting of plural arrays of the cord-like carriers which are hung in a vertical direction and in parallel to single or multiple stages into a reaction column. CONSTITUTION:The waste water poured from a waste water feed port 15 to a water pressure drop detecting pan 17 falls by gravity in a waste water feed pipe 20 and ascends by passing the spaces between the arrays of the cord-like carriers 12 hung in parallel in the vertical direction as shown in the figure a white arrow W after arriving at the bottom of the reaction column 10. The waste water 1 comes into contact with the bacteria held on the cord-like carriers 12 and is cleaned during the ascending. The cleaned and treated water 4 is passed through a water collecting pan 19 and a water sealing device 24 and a discharged to the outside of the reaction column 10. The carriers 12 formed to a cord shape and are hung in parallel in the vertical direction guide the waste water upward and since the cord-like carriers 12 are arranged along the flow of the waste water, the deposition of the suspensible floating solids and sludge on the surface thereof is extremely decreased and the clogging of the cord-like carriers 12 and the carrier units 11 thereof is prevented.
