Claims (6)

1. Способ обработки отходов, загрязненных тяжелыми металлами, отличающийся тем, что осуществляют следующие стадии : определяют кислотность загрязненного материала, осуществляют частичную нейтрализацию материала, если последний является кислотным, добавляют водный раствор ортофосфорной кислоты и ее соли щелочного металла, получают гомогенную пасту из образовавшейся смеси, добавляют к пасте оксид кальция (СаО) и/или гидроксид кальция (Са(ОН)2), высушивают пасту на воздухе.1. The method of treatment of waste contaminated with heavy metals, characterized in that the following stages are carried out: the acidity of the contaminated material is determined, the material is partially neutralized, if the acid is acidic, an aqueous solution of phosphoric acid and its alkali metal salt are added, a homogeneous paste is obtained from the resulting mixture , calcium oxide (CaO) and / or calcium hydroxide (Ca (OH) 2 ) are added to the paste, the paste is dried in air. 2. Способ по п. 1, отличающийся тем, что загрязненный материал перемешивают. 2. The method according to p. 1, characterized in that the contaminated material is mixed. 3. Способ по п. 1 или 2, отличающийся тем, что на тонну отходов, которые нужно перевести в инертное состояние, добавляют между 50 кг и 350 кг пылевидного оксида кальция и/или гидроксида кальция. 3. The method according to p. 1 or 2, characterized in that per ton of waste to be converted to an inert state, between 50 kg and 350 kg of pulverized calcium oxide and / or calcium hydroxide are added. 4.
