ИСПОЛЬЗОВАНИЕ МОДИФИЦИРОВАННОГО ВЕРМИКУЛИТА ДЛЯ ОЧИСТКИ СТОЧНЫХ ВОД ЭЛЕКТРОХИММИЧЕСКИХ ПРОИЗВОДСТВ

There were proposed physicochemical treatment methods highly electroplating effluents containing ions of nickel, copper and zinc using modified forms of vermiculite. In the first step purification is carried out by coagulation with soapy water (purification up to 99%). In the second stage, the resulting dilute solutions were subjected to electrochemical treatment with addition of NaCl using oxide-ruthenium titanium anode and cathode. For nickel and copper galvanic wastewater was introduced the third stage of adsorption by aftertreatment sorbents based on vermiculite in a dynamic mode. The highest degree of purification by nickel and copper ions was achieved by using vermiculite treated with 12% hydrochloric acid and cellulose
