Abstract
FIELD: industrial sewage purification, textile industry dye-works and finishing works. SUBSTANCE: order of realization stages of reactantless and with reactant flotation purification is changed, inorganic flocculant is substituted for cation organic flocculant. As a result of increase of sewage purification degree of weighted substances, dye-stuff, surface-active substances it becomes possible to return 90 % surface-active substances for reusage, decreased reactants usage by 90 %, ten times decreased volume of flotation slime as compared with known method. EFFECT: method allows to provide high degree purification from impurities with low usage of reactant and small volume of flotation slime, prevents environment pollution. 1 dwg, 2 tbl
