Ultrasonic chemical treatment technology as a physical means and tool can produce a series of near-extreme conditions in the medium of chemical reaction. This energy can not only stimulate or promote many chemical reactions, accelerate the speed of chemical reaction, but also change the direction of some chemical reactions and produce some desirable results. The ineffective and miracle is ultrasonic chemistry. Ultrasonic chemistry can be applied to almost all chemical reactions, such as extraction and separation, synthesis and degradation, biodiesel production, microbial control, degradation of toxic organic pollutants, biodegradation treatment, cell comminution, dispersion and coagulation, etc.
