| 摘 要： | 采用超声吹脱—吸附工艺处理高浓度氨氮废水。在超声吹脱工艺的基础上,利用改性沸石对超声吹脱后的废水进行超声强化吸附处理,考察了沸石粒度、吸附时间、沸石投加量、吸附温度、吸附超声功率等因素对处理效果的影响。实验结果表明：超声吸附处理废水的优化工艺条件为沸石粒度0.198~0.245 mm、吸附时间60 min、沸石投加量4 g/L、吸附pH 7.0、吸附温度30 ℃、吸附超声功率100 W;在该条件下,超声吹脱—吸附工艺的总氨氮去除率可达77.39%,较单独超声吹脱工艺的41.98%大幅提高。

| Abstract: | The high-concentration ammonia nitrogen wastewater was treated by ultrasonic stripping-adsorption process. Based on the ultrasonic stripping process,the wastewater after ultrasonic stripping was treated by ultrasonic-enhanced adsorption with modified zeolite. The effects of zeolite particle size,adsorption time,zeolite dosage,adsorption temperature and ultrasonic power for adsorption were investigated. The experimental results show that the optimal process conditions for ultrasonic adsorption are as follows：zeolite particle size 0.198-0.245 mm,adsorption time 60 min,zeolite dosage 4 g/L,adsorption pH 7.0,adsorption temperature 30 ℃ and ultrasonic power for adsorption 100 W. Under these conditions,the total ammonia nitrogen removal rate by the ultrasonic stripping-adsorption process can reach 77.39%,which is greatly improved compared with 41.98% by the ultrasonic stripping process alone. |
