METHOD OF PURIFYING TECHNOGENIC WATERS

摘要

FIELD: chemistry.SUBSTANCE: method of purifying technogenic waters includes dissolution of polyethyleneglycol terephthalate in an organic solvent, supply of the obtained mixture into water to be purified and further floatation of the processed water at pH 708 with separation of ions of heavy metals. Polyethyleneglycol terephthalate is dissolved in glycerol in a ratio 1:1-1:3, with supply of the obtained mixture into water to be purified in an amount of 0.2-0.4 l/m.EFFECT: invention makes it possible to increase transparency of the purified water and increase concentration of oxygen dissolved in it with preservation of a high degree of purification.2 tbl
