Abstract
Способ очистки сточных вод от тяжелых металлов, по которому в очищаемую воду добавляют известковое молоко, соли железа и цеолит, отличающийся тем, что цеолит добавляют первым, а известковое молоко и соли железа после перемешивания цеолита с водой, затем воду последовательно отстаивают, аэрируют, обрабатывают импульсными барьерными разрядами и фильтруют, причем используют природный цеолит, измельченный до фракции не более 0,3 мм.A method of treating wastewater from heavy metals, in which milk of lime, iron salts and zeolite are added to the water to be purified, characterized in that the zeolite is added first, and milk of lime and iron salts after mixing the zeolite with water, then the water is subsequently settled, aerated, treated they are filtered by pulsed barrier discharges, using natural zeolite, crushed to a fraction of not more than 0.3 mm.
