FIELD: water treatment.
SUBSTANCE: invention relates to water purification technology, in particular, to purification of waste water from copper ions by sorption. Method of purifying waste water from copper ions involves treatment with a sorbent, which is a blast-furnace granulated slag, pretreated with 10 % silica sol, and cleaning is carried out by filtering through a sorbent with a layer thickness of 0.04–0.05 m and grain size of 2.5–5 mm.
EFFECT: reduced consumption of sorbent and increased rate of filtration.
