FIELD: water treatment.
SUBSTANCE: invention relates to the technology of water treatment, in particular to the treatment of wastewater from heavy metal ions by sorption. The method for wastewater treatment from heavy metal ions is carried out by settling in the presence of a sorbent modified with potassium iodide crystals. As a sorbent, hardening products of magnesia binders obtained by mixing magnesium oxide with one-molar solutions of magnesium chloride, with a size of 10×10×10 mm, are used.
EFFECT: decrease in sorbent consumption.
