The invention provides a traveling wave type ultrasound reaction vessel, which relates to a device for processing liquid by using the ultrasound cavitation effect. The traveling wave type ultrasound reaction vessel comprises a box body (3), at least one pair of ultrasound energy exchangers and an ultrasound energy exchanger driving circuit, wherein the box body (3) is used for containing liquid to be processed, each pair of ultrasound energy exchangers consists of a first energy exchanger (2) and a second energy exchanger (6) which are respectively arranged on the box wall in opposite directions, and ultrasound traveling waves are formed in the box body of the reaction vessel by the overlapping of ultrasound standing waves with the 90 degrees of phase difference on space and 90 degrees of phase difference on time. The sound reaction vessel uses a traveling wave ultrasound field for working. Although each field point has different time phases, each field point has the same sound pressure amplitude value in theory. Because the intensity of the sound cavitation effect in the liquid only depends on the sound pressure amplitude value, and is irrelevant with the phases of the sound pressure, the sound cavitation effect in the traveling wave ultrasound field is more uniform than that in the standing wave ultrasound field.
