FIELD: chemistry.
SUBSTANCE: method includes coagulation, settling in a two-section stabilisation tank and recycling purified water in a closed cycle. The coagulant used is a polymer-colloidal complex coagulant, which is obtained in advance by mixing a water-soluble polyelectrolyte - polydimethyldiallylammonium chloride, aluminium polyoxychloride and a copolymer of an acrylamide with a quaternary ammonium salt of dimethylaminoethyl methacrylate with molecular weight of 8-10 million units and degree of charge of 38-40 in molar ratio of 2:1:1.
EFFECT: high efficiency of aggregating suspended substances in settling tanks, high output and efficiency of clarifying and recycling conditionally clean water, environmental safety of a water treatment plant.
