Popis: Dual-frequency ultrasonic assisted ozonation was proposed to degrade pesticide wastewater. The frequencies of ultrasound were 28 kHz and low-MHz (208 kHz, 495 kHz, 679 kHz and 890 kHz). The influence of ultrasound frequency was investigated in this paper. The electrical conductivity of deionized water was measured under different conditions, and degradation rate of acephate solution was used to verify degradation effect of the treatment. The results implied that the 208 kHz system was suitable for ozone dissolving and 495 kHz system was suitable for acephate degradation.
