摘　　要：实验研究了各种条件下超声催化氧化废水中NH3-N的去除效率,并讨论了最优条件组合。实验表明,在超声催化氧化废水中NH3-N时,当pH值为10,温度为60℃,反应时间为90min,以Ag2O+CuO为催化剂的超声催化作用下,NH3-N的去除率可以达到81.5%。The experimental stud the removal efficiency of wastewater ammonia nitrogen under various condi- tions by ultrasonic and catalytic oxidation, and discussed the optimal condition combination. Experimental results showed that,in the ultrasonic and catalytic oxidation wastewater ammonia nitrogen, when the pH=10, the tempera- ture of 60℃, the response time for 90 minutes, with Ag20＋CuO as catalyst under ultrasonic catalysis, ammonia ni- trogen removal rate to 81.5%.
