Reducing Pollution of the Transboundary Irtysh River by Means of Industrial Wastewater Treatment by Natural Sorbents
Abstract
The paper presents the method of reducing industrial waste pollution by cleaning it with acid and alcali activated bentonites. The results of laboratory studies industrial wastewater from heavy metals Pb (II), Zn (II), Cu(II). Bentonites studied in its natural form and conducted experiments to determine the degree of industrial wastewater polymetallic enrichment plants depending on the weight of bentonite and bentonite contact time and industrial runoff. A method of treatment of industrial effluents polymetallic enrichment plants using acid-activated bentonite horizon 14 neutralization with ammonia and washing with distilled water. The authors defined the way of disposal of residual waste bentonite as its use as an additive in the production of ceramic bricks.
