Recently, the application of ultrasound for degradation of hazardous chemical compounds has been investigated. And, many studies have been made on the degradation of hazardous organic compounds by combining ultrasonic irradiation with UV light irradiation in the presence of TiO_2 particle. However, from the viewpoint of process intensification, it is found that the synergy effect has not been obtained. On the other hand, the degradation of hazardous organic compounds by direct ultrasonic irradiation in the presence of TiO_2 particle has been investigated in complete darkness. In this study, indirect ultrasonic irradiation method was applied to degradation process of phenol. We focused on the effects of position of the reactor on degradation of phenol, radical generation and ultrasonic power inside the reactor. In results, it is considered that radical generation and degradation rate of phenol were influenced mainly by the positional relation between reactor and transducer. In addition, the degradation rate was improved by addition of TiO_2 particle. On the other hand, it is found that particle addition effect was influenced by the reactor's position.
