Abstract
The optimized processing conditions for treatment of wastewater containing ammonia nitrogen with ultrasonic stripping orthogonal tests were as follows: pH of 11,stripping times of 90 min,temperature of 40 ℃,and ultrasonic power of 80 W.The removal efficiency of ammonia nitrogen under the optimal stripping condition amounted to 99%.The concentration of ammonia nitrogen would be less than 100 mg/L.
