摘要： PROBLEM TO BE SOLVED: To provide a construction method for a waste disposal plant which is capable of increasing as waste housing capacity at a low cost. SOLUTION: A vertical type waste disposal chamber 10 is formed at the bottom of a depression type waste disposal plant 1. The vertical type waste disposal chamber 10 is provided with a bottom sealing works 13 and vertical sealing works 14. The upper opening of the vertical type waste disposal chamber 10 is closed by a waterproof cap 18.

摘要： PROBLEM TO BE SOLVED: To provide simple equipment for decontaminating the contaminated soil, in which high-efficiency decontamination can be carried out without expansion of contaminants and a method therefor. SOLUTION: A water barrier wall 2 is constructed to surround the region that the soil is contaminated by a toxic substance. A well 3 surrounded by steel pipes 21, 25 is dug on the downstream side of the contaminated region. The pipe 21 being in contact with the contaminated region is filled with a decontaminating agent 24. The pipe 25 being in contact with the uncontaminated region is provided with a gate 28 to be opened/closed. When the ground water in the region surrounded by the wall 2 passes among the particles of the contaminated soil, the ground water withdraws the toxic substance contained in the contaminated soil 1, passes through an opening of the pipe 21 and flows into the well 3. The toxic substance contained in the ground water is made harmless by the agent 24 in the pipe 21. When the concentration of the toxic substance in the well 2 is lower than the reference value, the ground water in the well 2 is discharged to the outside by opening the gate 28. When the concentration is equal to or higher than the reference value, the water in the well 2 is returned to the contaminated region again and decontaminated. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To promote the growth of a plant for a long period by improving acid soil using a microorganism. SOLUTION: The surface of the acid soil is scattered with a carrier for the microorganism comprising a natural polymeric material such as a bean-curd refuse and a carrier for the microorganism comprising an inorganic porous material such as zeolite and the acid soil is mechanically stirred and mixed with the carriers. The surface of the resultant soil is then scattered with seeds of the plant. A microorganism having the tolerance in the presence of high- concentration aluminum and adsorbing and removing aluminum ions is used as the microorganism and, e.g. Corynebacterium sp. SS-6994 described in Japanese Unexamined Publication Number 10-271990 can be used. The microorganism may previously be made to stick to the carrier and mixed together with the carrier into the soil. Otherwise, the microorganism, together with seeds of the plant, may be mixed with water and sprayed onto the surface of the soil by spraying. Shell lime, etc., together with the carrier, can be mixed into the soil.

摘要： PROBLEM TO BE SOLVED: To enable to easily cope with a distribution situation of contaminated soil and carry out purification treatment of a contaminated material in soil economically and in a short period. SOLUTION: An area containing soil contaminated with a hazardous material is classified in a planar manner into a heavily contaminated area and a lightly contaminated area. The heavily contaminated area C is dug through the interior by erecting a casing from a land surface and back-filled by a non-polluted material. The heavily contaminated soil in entirely replaced by carrying out the above repeatedly. The lightly contaminated area is provided with a pressurizing well 6 and a pumping well 7 at a fixed interval, a purifying treatment liquid injected from a tank 13 into the pressurizing well is penetrated into contaminated soil 15 and pumped up from the pumping well 7. The periphery of the pressurized well or the pumping well is replaced with sand soil 11 having good permeability by digging through erecting the casing and penetration of the treatment liquid is accelerated.
