Of the existing methods of treating industrial wastewater (mechanical, chemical, physico-chemical and biological), it is the biological method that is of interest today, due to the fact that it is based on the ability of microorganisms and higher aquatic plants to use a variety of pollutants as a power source in the process of life, which ultimately leads to the purification of contaminated water. In the practice of wastewater treatment by the biological method, a floating plant — eichornia (water hyacinth) —was best established on the surface of the roots of which selective microbiocenoses are formed, which contribute to active biodegradation and absorption of both organic and mineral substances. The paper shows the possibility of echornia absorption of pollutants in an indoor environment and proved the possibility of purifying contaminated water with aqueous hyacinth in an indoor environment.
