Abstract

The patterns of vibrocavitation purification of industrial wastewater from organic pollutants in the presence of nitrogen were studied. The optimal operating modes of the vibrocavitator were set: frequency – 37 Hz, temperature – 298 K, pressure – 0.1 MPa for cavitation treatment of wastewater. It is shown that the process of vibrocavitation destruction of organic compounds can be described by a first-order kinetic equation.
