    • PROBLEM TO BE SOLVED: To provide a method for recycling building sludge or the like. SOLUTION: When building sludge was mixed with waste newspaper pieces, stirred, further mixed with a polymer coagulant, and then stirred, the flowability of the mixture was eliminated and changed into an aggregate state. The soil A of this example was compared with other soils B and C. When one liters of the masses of the soils A, B and C were immersed in water for a prescribed time, the weights of the soils A, B and C were 1.7 kg, 1.3 kg and 1.1 kg, respectively. The changes of the weights of the soils for each day were measured under the same condition. The soil A of the present invention contained the largest amount of the water, and needed the longest period of about 30 days, until the water is gradually evaporated to give a constant weight free from the evaporation of the water. The soil of the present example can retain a large amount of water and has a long water-retaining period. Thereby, when used as culture soil, the soil can reduce the frequency of watering treatments, can suitably germinate the seeds of plants, and can allow the plants to grow.

    • PROBLEM TO BE SOLVED: To separate or thicken efficiently various kinds of solids having different specific gravities by ultilizing characteristics of a method by a Coanda spiral flow by a method wherein a swirl flow of a solid-liquid mixed phase fluid is generated to an upper stream side in a pipe line wherein the solid-liquid mixed phase fluid is conveyed, and the fluid near an axial center of the generated swirl flow is extracted. SOLUTION: A solid-liquid mixed phase fluid is firstly allowed to flow in a tangential direction of an influent part large diameter cylinder 2 from a tangential influent pipe 1 to generate a swirl fluid in the influent pipe large diameter cylinder 2. Then, the solid-liquid mixed phase fluid is allowed to pass through a diameter-gradually-diminishing pipe 3 to strengthen the swirl flow, and the strong swirl flow of a large free vortex component is generated in a swirl flow pipe line 4. In the spiral flow pipe line 4 at this time, a solid of a less specific gravity than that of the liquid and the solid of a large specific gravity which comprise the solid-liquid mixed phase fluid, are respectively collected in an axial central part of the swirl flow to form the thickened solid-liquid mixed phase fluid. Then, the thickened solid-liquid mixed phase fluid is extracted from a downstream side extracting pipe 5 arranged concentrically in the swirl flow pipe line 4, and the solid is taken out by separation from the swirl flow pipe line 4.

    • PROBLEM TO BE SOLVED: To reduce freezing time by applying electric charge or a magnetic field to a part of a pipeline to flow a refrigerant. SOLUTION: Electric charge or a magnetic field is applied to freezing pipes 1, 2. Therefore, since a metallic ion and an inorganic ion can be gathered to the periphery of an electrode or a magnetic pole on the outer periphery of the freezing pipes 1, 2, when freezing starts from soil 3 in the vicinity of the freezing pipes, moisture in the soil 3 freezes, and at the same time, the metallic ion and the inorganic ion can also be frozen, so that freezing efficiency is improved by preventing the deviatory existence in the soil. A Coanda spiral flow is desirably used to flow in and discharge a refrigerant. The refrigerant can be easily recovered by turning air and a waterdrop gathered in a bent pipe and a U-shape pipe to the shaft center when the Coanda spiral flow is flowed to a pipeline having, for example, the U-shaped pipe or the bent pipe. Therefore, besides freezing time can be reduced, the refrigerant in a freezing outer pipe, a freezing inner pipe and a U-shaped pipe can be easily discharged.
