A waste liquid treatment apparatus with enhanced treatment capacity for a pre-treatment facility of a liquid radwaste treatment system for a nuclear power plant. The waste liquid treatment apparatus includes: a water tank into which a waste liquid is introduced and from which filtered permeated water is discharged; a waste liquid introduction section through which waste liquid is introduced into the water tank; submerged membranes annularly disposed and spaced apart from each other for filtering foreign substances from the waste liquid; a permeated water suctioning section suctioning the filtered water of the waste liquid and discharging the filtered water outside the water tank; an air supplying section supplying compressed air to the submerged membranes to remove foreign substances; and a porous support plate supporting the submerged membranes.

Device for treatment of waste liquid

Disclosed is a method and device for simply and safely preparing, using a direct synthesis process at room temperature, a radioactive methyl iodine (CHI) tracer for use in evaluating the ability of impregnated activated carbon to adsorb radioactive organic iodine according to ASTM D 3803 (Standard Test Method for Nuclear-Grade Activated Carbon), in which the tracer can be directly synthesized by mixing radioactive sodium iodide (NaI) with methyl iodine (CHI) at room temperature under reduced pressure, thus shortening excessive synthesis time and decreasing the probability of radiation exposure due to leakage of volatile material during the distillation.
