The ultrasonic probe of the energy-collecting type of the ultrasonic vibrating rod concentrates the energy, and can obtain the strong sound intensity on the ultrasonic radiation end surface The emission end face of the probe is generally designed as a detachable type, so that the probe with the appropriate end face size can be chosen at any time according to the required sound intensity, when the probe is cavitation serious corrosion, only need to replace the end, rather than replace the expensive whole vibrator. Ultrasonic vibrator can be used to treat all kinds of refractory organic wastewater, at present, it has been applied to the treatment of wastewater containing aromaticity, Polycyclic aromatic hydrocarbon, phenols, chlorinated hydrocarbons, chlorinated hydrocarbons, organic acids, dyes, alcohols, ketones, etc. . The equipment has been used to treat papermaking wastewater, printing and dyeing wastewater, tanning wastewater, coking wastewater, pharmaceutical wastewater, landfill leachate, etc. .

In addition, in some scenic lakes, rivers ultrasonic vibrator can also be used to kill algae, algae. The mechanical effect, cavitation effect, thermal effect and sound flow effect of ultrasonic wave make the algal cell break, the chemical bond break in the Substance Molecule Act on the outer wall of the algal, and make it break and die, it can cause a series of biological effects such as ascending and breaking of algal vacuoles, cell death or growth inhibition, and cavitation makes the micro-bubbles in the liquid expand rapidly and then close suddenly, in order to eliminate algae and balance water environment, shock wave and jet are produced. Low intensity ultrasound destroyed the structure and function of phycobilium and interfered the synthesis of chlorophyll, so as to inhibit the growth of algae.
