FIELD: treatment plants.
SUBSTANCE: invention relates to technology of purifying waste water from metal ions by sorption. Method of purifying waste water involves treating water stressing cement, mixing and separation of sediment. Self-stressing cement is introduced into water in amount of 80 mg/l at concentration of metal ions in purified water from 1 to 10 mg/l.
EFFECT: technical result consists in reducing consumption of sorbent with wider range of extracted metals.
