Title:
PURIFICATION APPARATUS AND PURIFICATION METHOD FOR PURIFYING CONTAMINATED SOIL
Document Type and Number:
Japanese Patent JP3766933
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a purification apparatus and a purification method which downsize each component unit and efficiently treat hydrophobic material-containing contaminated soil or waste water.
SOLUTION: The purification apparatus has a dehydrator 3 that particularly compresses and dehydrates sediment sludge 15, 15a precipitated in a coagulation sedimentation tank 2, a highly purified water recovery chute 61 that recovers highly purified water 16' squeezed out from a squeeze filter press in the dehydrator 3, a belt conveyor 62 that recovers low purified water squeezed out in the same way and clods, and a filtration-adsorption means 5 comprising a filtration adsorbent 23b. The highly purified water 16' squeezed from the squeeze filter press is recovered by the recovery chute 61 and purified with the filtration adsorbent 23b. As the filtration adsorbent 23b is composed of only one spongy urethane resin, the processing time can be considerably reduced, and all units composing the purification apparatus can be miniaturized.
