Waste water treatment with humic substances from coal from heavy metals

Abstract

The activities of many industrial enterprises often lead to pollution of the environment with wastewater containing
harmful substances that have a rather serious negative impact on human health and the state of the biosphere as a whole.
The harm of heavy metals to a living organism is due to their ability to bioaccumulate and concentrate when
moving along the trophic chain, which leads to disruption of the functioning of organ systems. In this regard,
wastewater treatment of industrial enterprises should be carried out until almost complete removal of heavy metals. But using only traditional methods, this is difficult to achieve. One of the most common methods of wastewater treatment
from heavy metals is sorption and ion exchange methods.
This article is devoted to the treatment of wastewater from heavy metals using humic substances obtained from
coal. The results of the studies showed that humic acid well sorbs heavy metals contained in wastewater. These studies
are relevant and bring novelty to the process of wastewater treatment.
