Abstract
ADC foaming agent condensation water belongs to high concentration ammonia nitrogen wastewater and particularly contains a large amount of refractory material and biological organisms toxic substances.According to this characteristic,experiments of removal of ammonia nitrogen from wastewater by stripping were carried out,influencing factors on the removal rate of ammonia-nitrogen including pH value,temperature,air flow rate and aeration gas were investigated.On this basis,the application of ultrasound to wastewater treatment was studied.The results indicated that the removal rate of ammonia nitrogen reached 92% under the optimal conditions as pH 10,temperature 30 ℃,air flow rate 1.0 L·min-1,ultrasonic power 400 W and ultrasound stripping times of 180 min.
