ML dichlorovs(30 mg/L) is oxidized by ultrasonic in 100 mL beakers. When power is 200 W,600 W and 800 W,the removal is low,for the largest removal is less than 20% at the treatment of 60 min, while the removal is 48% when power is 1000 W. On the mean while, cost raises a lot. Consequently, treatment of dichlorovs by ultrasonic is worthless.
