Claims (1)

Способ очистки сточных вод от цветных и тяжелых металлов, в присутствии иона растворимой соли щелочного металла, включающий электрофлотацию с нерастворимыми анодами, отличающийся тем, что с целью повышения степени очистки в очищаемую воду с pH=9,0 - 10,0 вводят ортофосфат-ионы PO 3- 4 в виде растворимой соли ортофосфата натрия при массовом соотношении извлекаемого иона металла к введенному ортофосфат-иону 1:(0,5 - 1,0).A method of treating wastewater from non-ferrous and heavy metals, in the presence of an ion of a soluble alkali metal salt, including electroflotation with insoluble anodes, characterized in that in order to increase the degree of purification, orthophosphate ions are introduced into the purified water with pH = 9.0 - 10.0 PO 3- 4 in the form of a soluble salt of sodium orthophosphate at a mass ratio of the recoverable metal ion to the introduced orthophosphate ion 1: (0.5 - 1.0).
