Abstract

Sonophotocatalysis is extensively used in the treatment of wastewater in recent years. A new type of sonophotocatalytic reactor based on the radial ultrasonic technology was designed. The experimental results showed a synergistic enhancement effect of radial sonolysis and photocatalysis on the degradation of organic pollutants. The optimum conditions for the process are initial methylene blue concentration 10 mg L-1, the added P25 catalyst concentration 0.1 g L-1 and ultrasonic intensity 200 W, ultraviolet (UV) lamp intensity 100 W. Under the optimum conditions, the degradation rate can achieved 90 %. The results showed that the distribution of radial ultrasound wave was more uniformity than other sonophotocatalytic reactors. It improved the efficiency of the degradation of organic pollutants. The radial sonophotocatalytic degradation of methylene blue followed pseudo-first order kinetics. The application of radial ultrasonic technology holds a promising future on the treatment of high concentration of persistent organic pollutants.
