It has been studied an effect of ratio between arene and alkene organic compounds, as components of olefin production wastewaters, and sodium hypochlorite, as liquid waste of caustic soda and chlorine synthesis, on their interaction. The organics total content was expressed by a value of chemical oxygen demand. A fundamental possibility of the mutual neutralization was confirmed. Use of a cavitation field significantly reduces duration of the process and the ratio between sodium hypochlorite and organic compounds. The implementation of this process under adiabatic conditions allows to accelerate the neutralization due to the environment temperature increase caused by cavitation. It was found from calculated process kinetic parameters that magnetostriction radiator causes cavitation excitation in the diffusion area.
