The article discusses the methods and ways of protecting the environment by cleaning the exhaust gases of power plants, using the effect of vibration turbulization. The advantages of using jet devices over the use of vibration technology in eco-protective installations are theoretically substantiated.

Keywords: vibration turbulization, environmental protection technologies, energy efficiency

This article provides a theoretical description of the vibration turbulization process. It is shown that with constant physicochemical properties of the system, the volumetric mass transfer coefficient in the liquid phase during vibration turbulization depends on the mixing power and gas content.

Keywords: vibration impact, mass transfer, gas content

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.
