ADSORPTION TOWER FOR CONTAMINATED WATER TREATMENT, AND CONTAMINATED WATER TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an adsorption tower for contaminated water treatment capable of improving the availability of a filled adsorbent by avoiding the increase in the pressure loss due to a suspended matter and oil.SOLUTION: The adsorption tower includes: a cylindrical or spherical vessel 1; an adsorbent 2 that is filled into the vessel and adsorbs metal ions from contaminated water; a drainage channel 3 disposed in an upper or lower part of the vessel; and a plurality of water feed channels 4 disposed at a plurality of upper and lower places in the vessel in order to introduce the contaminated water into the vessel.SELECTED DRAWING: Figure 1
