Abstract
FIELD: waste water purification. SUBSTANCE: cationic flocculant designed for multiply increasing efficiency of removing from waste water suspended substances, anionic surfactants, petroleum derivatives, and other organic impurities, as well as for using in processes of mechanical dehydration of sediments includes alkylation with halogen-organic compounds and polymerization of 2-methyl-2-vinylpyridine. Method is distinguished with that, water-emulsion polymerization of 2-methyl-2- vinylpyridine is first performed and resultant latex with molecular weight 100-300 thousand Dalton is then treated with stoichiometric quantity of benzyl chloride in presence of stabilizing additive. As the latter, polymer quaternary ammonium base is used in amount 6-8 weight parts per 100 weight parts of latex polymer, and the process is carried out at 45-65 C. EFFECT: enhanced efficiency of process.
