摘要： PROBLEM TO BE SOLVED: To provide a water purifier requiring only a small floor space and having a simplified structure and excellent and economical purifying performance. SOLUTION: This water purifier 1 has concentrically arranged outer tank 2 and inner tank 10. The bottom of the inner tank 10 is open and allowed to communicate with the outer tank 2. The annular space between both tanks is horizontally divided to upper and lower parts by an active-soil unit 20.A contact material 40 for adsorbing the solid in polluted water is provided in the space below the active-soil unit and in the inner tank. A suction pipe 8 is fixed in at center of the outer tank 2. The polluted water introduced into the upper part of the outer tank 2 from an inlet pipe 31 moves circumferentially and then downward. The water is then treated by passing it through the active- soil part, brought into contact with the contact material 40, revolved introduced into the inner tank 10, sent upward and discharged to the outside of the tank from a purified water discharge means 50. The solid released and accumulated at the bottom is efficiently sucked out to the outside of the tank through the suction pipe 8. Power is not needed in the operation, which makes the device economical.

摘要： PROBLEM TO BE SOLVED: To reduce the quantity of waste by adding a soil particle flocculation accelerator to muddy water to flocculate soil particle components in the muddy water to form soil particle aggregate, settling the soil particle aggregate to separate it from the supernatant, and subjecting the precipitated soil particle aggregate to dehydration treatment by a separation means. SOLUTION: When muddy water generated from a drilling site or the like for a shaft is fed into a muddy water storage tank 2 from a feeding pipe 1, the muddy water overflows an agitation tank 5 and flows into the agitation tank 5. At this time, a scooping pump 6 in a flocculation accelerator storage tank 3 is operated to feed a flocculation accelerator into the agitation tank 5 through a feeding pipe 4 and obtain a liquid mixture of the turbid water and the flocculation accelerator here. Next, the liquid mixture is fed to a water receiving tank in a sedimentation tank 8 by a scooping tank 7, and during this period, the soil particle components are flocculated to form flocs. Next, a flow that has overflowed the water receiving tank is caused to fall along an umbrella-shaped partition wall 11, and successively, it is slowly raised in the sedimentation tank 8. Here, the flocs are subjected to sedimentation while their diffusion is restrained.

摘要： PROBLEM TO BE SOLVED: To eliminate disaster by overflow of a large quantity of rainwater by a rainwater overflow protective facility of simple structure. SOLUTION: Plural storage tanks 1 are embedded at a specified interval in a line in a rainwater overflow control zone. Openings 2 in an upper surface are set close to the ground surface, so rainwater flowing on the ground surface gets into the opening 2. A water impermeable wall body 3 exists between the storage tanks 1, 1. A suction pipe 4 exists in the storage tank 1, and upper end parts of the respective suction pipes 4 are connected to a common connection pipe 6. A vacuum pump 8 is connected to one end of the connection pipe 6. A discharge pipe 9 is connected to a discharge port 8b of the vacuum pump 8. In a city area, quantity of rainwater sucked to the ground in rainfall is less, but a large quantity of rainwater flows at once to be concentrated to a river or the like at the time of rainfall to cause a flood. By providing a rainwater outflow protective facility at a necessary position in the city area, rainwater fallen onto the ground surface is temporarily stored in the storage tank 1. By driving the vacuum pump 8 at a proper timing, rainwater W in each storage tank 1 is discharged to a drain facility. Overflow quantity of rainwater can thus be adjusted to prevent floods or landslides.

摘要： PROBLEM TO BE SOLVED: To economically construct an underground storage tank without any auxiliary construction methods even under conditions where an excavation wall surface is not self-supportable and there is a spring. SOLUTION: An excavation guide earth retaining wall 20 is provided within a range where an excavation wall surface can self-support, and surrounded by concrete 21. Muddy water is introduced into the retaining wall 20, and a nearly circular pit is excavated in the muddy water excavation system. A shaft is excavated while muddy water 23 corresponding to the amount of excavation soil is being replenished into the pit. An assembled storage structural body 10 is suspended in the muddy water 23 of a pit 22 where muddy water excavation has been completed. Concrete is placed into a bottom part through a tremie pipe 26, thus forming base concrete 27. A hardener 29 is injected into the gap between the outer-periphery surface of the storage structural body 10 and an excavation wall surface. Overflowing muddy water is discharged by a pump. After conforming the consolidation of the base concrete 27 and the hardener 29 being injected between the storage structure body 10 and the excavation wall, muddy water in the water storage layer is discharged.

摘要： PROBLEM TO BE SOLVED: To provide a processing device for sedimentary soil capable of efficiently processing the sedimentary soil scooped up from a river and capable of processing the muddy water left in the river. SOLUTION: This processing device is provided with cutoff walls 2, 2 partitioning a removal region 3 in a river 1, a force feed means 40 force-feeding the sedimentary soil in the removal region to the outside, a water dripping means 25 separating water from the force-fed sedimentary soil, and a soil improving means 30 applying the soil improving process to the water-dripped sedimentary soil 4. The improved sedimentary soil is carried out by a carrier 24. The muddy water separated from the sedimentary soil is returned to the removal region 3 by a muddy water return pipe 28. A soil grain precipitating agent is mixed with the muddy water in the removal region 3 and stirred, and the muddy water is separated into supernatant water and a soil grain flock. A water-permeable partition member provided in the removal region is moved to allow the supernatant water to pass, and the soil grain flock is accumulated for the final disposal.
