The peculiarities of the process depending on the conditions of its implementation are established: thermal regime (adiabatic and isothermal regimes); process temperatures; the presence of oxygen in the reaction medium; time operation mode (stationary mode and initiation mode), pressure at the inlet to the hydrodynamic cavitator. It is shown that the decomposition of benzene and toluene in the cavitation field occurs according to similar dependences, and the destruction of phenol occurs only when using an oxidizing reagent. It is established that in the conditions of cavitation decomposition of benzene and toluene in the presence of oxygen in the system their deep oxidation to carbon dioxide and water takes place. During the cavitation conversion of phenol with the participation of hypochlorite solution, intermediate compounds - phenolates - are formed. The energy indicators of cavitation destruction of aromatic compounds are established. The technological scheme of cavitation neutralization of aromatic compounds in wastewater is offered Product Description popup.authors Helesh Andrii B. Zin Olha I Kurylets Oksana H.
