METHOD OF TREATING NATURAL AND WASTE WATERS CONTAINING IRON, HEAVY, AND NONFERROUS METAL IONS

摘要

FIELD: water treatment. SUBSTANCE: invention is focused on treating plating waste water, rainfall effluents, and drinking water. Water to be purified is treated by reagent and then settled to separate sediment. As reagent, 3-10% aqueous suspension of alkylcarboxysiloxane mixture is used, compound being defined by a general formula where R is CHAB, CHAD, or ordinary bond; A and B are (x=0-16) or (y=0-16 and z=0-16) and D is . EFFECT: increased purification efficiency. 3 cl, 3 tbl
