Washing treatment system and washing treatment method for contaminated soil
12 Jul 22
A washing treatment system for contaminated soil, including: a classifier that is configured to obtain a sand fraction having a particle size within a predetermined range and a fine-grained fraction having a particle size smaller than the predetermined range, from contaminated soil containing one or more contaminants selected from dioxins and agricultural chemicals; a detaching/washing unit that is configured to detach a contaminant particle containing the from a surface of the sand fraction; a removal unit that is configured to generate air bubbles in a presence of water containing a flotation chemical, allows the detached contaminant-bearing particles to attach to the air bubbles to form froth, and removes the froth to obtain a first slurry containing primary purified soil; and an up-flow washing unit that is provided downstream of the removal unit, and is configured to supply the first slurry into up-flow water to purify the primary purified soil.

Utility
Rotary inertial mass damper
4 Jan 21
The rotary inertial mass damper has a configuration in which the rotary shaft of the oil-pressure motor rotates due to oil pressure of operating oil that is extruded from an oil chamber through reciprocating movement of the piston rod, and viscosity resistance is produced in operating oil that circulates in the connection pipes.
