Abstract

Wynalazek dotyczy sposobu oczyszczania wodnych scieków o wysokiej zawartosci metali, zwlaszcza Ag i Cu, oraz kompozycji do zastosowania w tym sposobie. Sposób oczyszczania scieków wodnych o zwiekszonej zawartosci metali sklada sie z dwuetapowego procesu, w którym w pierwszym etapie stosuje sie mieszanine specjalnie dobranych rozpuszczalnych soli oraz w pelni biodegradowalnego wielkoczasteczkowego polimeru - chitozanu. Nastepnie odfiltrowuje sie wytracony osad i w drugim etapie oczyszczania ponownie do przesaczu dodaje sie chitozan.The invention relates to a method of treating aqueous wastewater with a high metal content, in particular Ag and Cu, and to a composition for use therein. The method of treating water effluents with an increased metal content consists of a two-stage process, in which in the first stage a mixture of specially selected soluble salts and a fully biodegradable high-molecular polymer - chitosan are used. Then the precipitate is filtered off and in the second stage of purification, chitosan is added to the filtrate again.
