The present invention is disclosed an array-type-transducer-based high-power ultrasound delivery system which includes a support bracket, an array-type ultrasound transducer, and a plurality of containers. The support bracket includes a plurality of grooves, and the array-type ultrasound transducer includes a clamp and N ultrasound transducers. The clamp includes a plurality of wedges configured for engaging in the grooves of the support bracket and thereby connecting the array-type ultrasound transducer to the support bracket. The containers are arranged in a two-dimensional matrix so that the ultrasound transducers of the array-type ultrasound transducer can dip into and leave the ultrasound-conducting medium in the containers vertically. The disclosed system features high operation speed and low labor requirement. Moreover, the depth by which and the time for which the ultrasound transducers dip into the ultrasound-conducting medium in the containers can be controlled and quantified.
