FIELD: purifying of industrial sewage water with the use of reactants, in particular, of fur processing industry.
SUBSTANCE: method involves introducing into sewage water coagulant, such as aluminum sulfate, and flocculant; separating resultant sediment; using flocculant, in particular, polymer - product of reaction of polyacrylamide and sodium salt of acrylic acid with molar weight of 12.6·106 and ionogenic link content of 19.8 mol% in an amount of (0.3-0.5)·10-3 g/l and aluminum sulfate in an amount of 0.3-0.5 g/l. Method provides for purification of up to 98% of sewage water.
EFFECT: increased extent of purification.
