Abstract
PURPOSE: To treat absorbed liquid in closed system and to operate at constant denitrification ratio for a long time by the process, in which a part of the filtrate is drawn out after gypsum recovery and carried to dust recovery cooler as well as Ca(OH)2 or CaCO3 is added to decompose and precipitate the metal salt (additive) in the filtrate and to use the salt circularly for absorbent.
