Claims (1)

Способ осаждения ионов тяжелых металлов из промышленных сточных вод, включающий введение щелочного нейтрализатора при величине pH, находящейся в пределах значений 4,0 ≤ pH ≤ 12,0, получение разноименно заряженных золей с их последующей взаимной коагуляцией, отличающийся тем, что осветленную водную фазу отделяют декантацией, а осадок многократно подвергают контакту со следующими порциями исходного раствора с последующей декантацией осветленной водной фазы.The method of precipitation of heavy metal ions from industrial wastewater, including the introduction of an alkaline catalyst at a pH value in the range of 4.0 ≤ pH ≤ 12.0, the production of oppositely charged sols with their subsequent mutual coagulation, characterized in that the clarified aqueous phase is separated by decantation, and the precipitate is repeatedly exposed to the following portions of the initial solution, followed by decantation of the clarified aqueous phase.
