Abstract

One of the priorities of modern environmental research is the development of theoretical and practical aspects of bioremediation of water bodies, based on the use of natural mechanisms of self-purification and self-healing of water bodies, the effect of which is associated with the activities of higher
aquatic plants (HAP) and microorganisms belonging to different types of cyanobacteria and microalgae.
The practical significance of these objects for bioremediation and post-treatment of water bodies is
determined by the uniqueness of their metabolic abilities (photosynthesis, respiration, a variety of carbon sources, the ability to absorb atmospheric nitrogen, etc.), high cumulative and destructive ability
against heavy metals and organic pollutants such as oil, petroleum products, phenols, etc. The aim of
the research was to study the process of wastewater treatment from heavy metals by the consortium of
HAP and microalgae in industrial wastewater. It is shown that the use of the consortium of HAP and
microalgae in wastewater treatment is very effective compared to their use in purification processes in
monoculture. It was found that the use of the consortium of HAP and microalgae improved water quality,
and the effect of purification from pollutants on some indicators was more than 95-100 %.
Key words: higher aquatic plants, microalgae, consortium, bioremediation.
