METHOD AND DEVICE FOR TREATING PERCHLORATE ION-CONTAINING LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a method for treating a highly-concentrated perchlorate ion-containing liquid, in particular a highly-concentrated perchlorate ion-containing liquid included in a supernatant liquid after regeneration of ion-exchange resin having adsorbed perchlorate ions, and to provide a device for treating a perchlorate ion-containing liquid.;SOLUTION: The perchlorate ion-containing liquid, in particular a perchlorate ion-containing liquid obtained by performing coagulating sedimentation of calcium sulfate to separate sulfuric acid by adding calcium carbonate to the supernatant liquid including highly-concentrated perchlorate ions is injected to a heating furnace at 550-950°C to pyrolyze the perchlorate ions, and pyrolyzed gas is made to pass through a gas absorbing liquid.;COPYRIGHT: (C)2013,JPO&INPIT
