Abstract
The article is devoted to the sorption treatment of industrial effluents, which contain heavy metal ions (HMI) by the natural clay mineral kaolinite - an activated adsorbent. The main sources of HMI receipts are revealed - industrial and agricultural production. The influence of heavy metals on human health is considered. The results of studies of wastewater treatment using filtration through an activated adsorbent of Ni2+, Cu2+, Zn2+, Cr6+, ions, mixed waste are presented. Dolomite and magnetite were chosen as activators. The optimal composition of activators has been determined. When using the proposed method of wastewater treatment, separation into streams of chromium-containing and acid-base wastewater is excluded. The high quality of purified water with an activated adsorbent makes it possible to use it in closed water use systems. The cheapness and availability of natural clay adsorbents, high performance properties, allow us to offer it as an industrial sorbent.
