Abstract: PROBLEM TO BE SOLVED: To provide a simple selection method for a separation membrane module capable of certainly making dioxins in waste water to a reference value or less and releasing it, and a simple selection apparatus.
SOLUTION: The method is a selection method for a separation membrane module using for cleaning treatment of the waste water containing the dioxins. The waste water containing the dioxins is passed through a plurality of separation membrane modules having different membrane pore diameters and a relationship of the membrane pore diameter and concentration of the dioxins in the filtered water is determined. The separation membrane module for making the dioxins in the released waste water to a reference value or less is selected.

Abstract: PROBLEM TO BE SOLVED: To provide a contaminated foundation purification method which can be applied to every foundation of a saturated sand foundation, an unsaturated sand foundation, a saturated viscous foundation and an unsaturated viscous foundation, is high in purification efficiency, and can attain the remarkable shortening of a treatment period, and to provide a purification device used therefor.
SOLUTION: In the contaminated foundation purification method, a contaminated foundation in situ is purified by using a stirring apparatus 10 provided with one or more stirring vanes 2 radiately fitted in the lower direction of rotary shafts, air injection ports 3 fitted to the prescribed places in the rotating regions of the stirring vanes 2 and gas suction ports 4 fitted to the prescribed places in the direction upper than the air injection ports 3 in the rotating regions of the stirring vanes 2. In this case, the stirring of in situ soil by the stirring vanes 2 and the injection of air into the rotating regions of the stirring vanes 2 are simultaneously performed, and contaminants are recovered from the gas suction ports 4 to the ground.

Abstract: PROBLEM TO BE SOLVED: To provide a method for force-feeding a fine grain material, in which the separation of the fine grain material is prevented while a fluid resistance can be lowered and the mixing ratio of a thickener can be reduced when the inside of a ground is supplied with the fine grain material such as sand, a silt, iron powder, iron oxide or the like together with water.
SOLUTION: A slurry containing the fine grain material, the thickener and water is prepared, the fine bubble-filled slurry is obtained by supplying fine bubbles from the bottom section of the slurry in an agitating tank and the fine bubble-filled slurry is force-fed into the ground by a pump.

Abstract: PROBLEM TO BE SOLVED: To provide a method for freezing and removing polluted soil, for making block-shaped frozen soil by utilizing a freezing technique and sealing the volatilization of a harmful substance or the malodor of waste with ice to more reduce an environmental risk than before while enhancing the removal/feed-out efficiency of polluted soil.
SOLUTION: This method for freezing and removing polluted soil has a cooling pipe arranging process for arranging cooling pipes in polluted soil, in which a pollutant is present, so as to make the distances between the center parts of the cooling pipes equal, a cooling process for supplying a freezing medium to the cooling pipes to form discontinuous frozen soil comprising the surface part of non-frozen soil and the remainder of frozen soil around the cooling pipes, and a frozen soil removing process for taking out the frozen part of discontinuous frozen soil to the surface of the ground.
