FIELD: waste treatment. SUBSTANCE: invention relates to removal of organic impurities formed in production processes or in consequence of man-caused catastrophes from substrate for further use of purified substrate in national economy. Method is based on adsorption of impurities by fine crumb (0.1-50 mcm) obtained by mechanical treatment of naturally occurring or synthetic polymer involving acoustic, including ultrasonic, action and subsequent polymerization of impurity mixture, part of substrate, and polymer crumb.
