Abstract
PURPOSE: To effectively wash the resins while decreasing the amount of the waste liquid after the treatment by supplying ion exchange resins together with water flow into regenerating towers which have beforehand been supplied with water up to near the free board drain pipe and discharging the clad-contg. waste liquid from the drain pipe.
CONSTITUTION: The contaminated ion exchange resins are admitted together with water flow through a pipe 4 into the 1st regenerating tower 1 which has beforehand been supplied with water up to slightly above a free board drain pipe 2 to be formed with the water layer shown by a water level 15 and the waste liquid containing clad portions is discharged from a drain pipe 2. Thence, when the amount of the resins sedimented on the tower bottom reaches the level of about 30W 35cm below the drain pipe 2, the supplying of the resins is suspended. Air is then press-fed from a pipe 8 into the tower 1 to perform scrubbing, thereby allowing the clad portions deposited on the resins to desorb into the water. Thence, a resin discharge pipe 5 and a lead-in pipe 4' are communicated and the clad-portion-contg. waste liquid and the resins in the 1st regenerating tower 1 are transferred into the 2nd regenerating tower 1' which has beforehand been supplied with water in the same manner as for the tower 1. The same operations having been made in the tower 1 are then continued.
