Claims (2)

1. Способ очистки сточной воды от хроматов путем пропускания воды через фильтры с высокоосновной анионообменной смолой с последующей регенерацией ее реакционным агентом, отличающийся тем, что регенерацию ведут растворами солей сильных кислот и щелочных металлов или их смесью, а полученные элюаты очищают от хроматов и повторно используют после корректировки состава и подкисления.1. The method of purification of wastewater from chromates by passing water through filters with a highly basic anion exchange resin followed by regeneration with a reaction agent, characterized in that the regeneration is carried out with solutions of salts of strong acids and alkali metals or a mixture thereof, and the resulting eluates are purified from chromates and reused after adjusting the composition and acidification. 2. Способ по п. 1, отличающийся тем, что в регенерационном растворе концентрацию хлоридов, сульфатов и нитратов щелочных металлов или их смесей поддерживают в пределах от 4 до 10 мас.% процентов, а значение рН до величины рН ≤ 3. 2. The method according to p. 1, characterized in that in the regeneration solution, the concentration of chlorides, sulfates and nitrates of alkali metals or mixtures thereof is maintained in the range from 4 to 10 wt.%, And the pH to pH <3.
