The main methods for removal dyes from wastewater and the essence of advanced oxidation processes are considered. The advantages of using solid-phase oxidizing agents compared to liquid-phase oxidants are presented. The influence of the specific power (P/V) of ultrasonic cavitation treatment on the efficiency and intensity of dyes degradation using advanced oxidation processes based on simultaneously activated by ultrasonic cavitation and catalysts of solid-phase oxidizing agents is analyzed. It was found that the degradation degree of Congo red using the advanced oxidation process “US/FeSO4/PPI” at P/V=68 W/L was 97.2 %, and the degradation rate constant was 2.401×102 M-1s-1. It was also found that in the case of Rh B degradation using the advanced oxidation process “US/MgMn2O4/SPC” at P/V=51 W/L, the degradation degree was 98 %, and the rate constant was 0.308×102 M-1s-1. The expediency of applying the energy-saving principal when selecting the mode of US treatment is substantiated. A principal technological scheme for dyes degradation was developed, which included combined (cavitation and catalytic) activation of solid-phase oxidizing agents (PPI or SPC).
