Possibilities of Using Higher Aquatic Vegetation in the Process of Treatment of Industrial Wastewater from Mining Enterprises

Abstract

The paper analyzes the possibility of using different higher aquatic vegetation (HAV) and its effectiveness in the treatment of industrial effluents of mining enterprises. The influence of various factors on phytoremediation processes is assessed: natural and climatic (ambient temperature, air humidity, illumination, water temperature) and chemical (pH of water, content of dissolved oxygen in water, concentration of pollutants in water, presence or absence of organic compounds). The cleaning efficiency of both one and several species of hydrophytes, both semi-submersible and free-floating, was analyzed. It was found that the greatest effect of phytoremediation is manifested with the complex use of groups of higher aquatic plants different in their species composition and place of growth.
