Research on Ultrasonic Focalized Decomposition of Dying Wastewater

A new method called ¿ultrasonic focalized decomposition¿, which is presented in the paper, is a relatively safe and efficient and economical treatment for high concentration of refractory dying wastewater. Ultrasonic make micro-bubble in the sewage generate cavitation bubble collapse, the capacity of dissolved air in the liquid is improved by pressurized and dissolved air dynamically; ultrasonic focalized method presented here is for saving energy and improving the field strength; frequency automatic tracking system was used to make ultrasonic vibration transducer system have constant power output regardless of the work condition. A set of experimental apparatus was designed on the basis of theoretical research. The effects and the corresponding factors of ultrasonic decomposition of dying wastewater were further explored and analyzed.
