METHOD FOR TREATMENT OF SALINE WATER OF NA-CATIONIC PLANTS

摘要

FIELD: treatment of saline water of Na-cationic plants; applicable in plants of ion-exchange water softening of thermal power production using softened water. SUBSTANCE: saline sewage water of Na-cationic plants is treated with solution of technical soda with consumption of 0.8-1.1 equivalents per equivalent of calcium and magnesium cations and pH 8.9-9.3 of treated suspension ensuring efficient precipitation of calcium and magnesium carbonates. EFFECT: higher efficiency. 1 cl, 1 tbl
