摘要:
自制一种复合型氨氮吹脱助剂,引入外加场即超声场和磁场来处理氨氮废水,研究反应的最适宜条件。结果表明,质量浓度1 910～2 000 mg/L的废水在pH为11、助剂的投加量为0.084 8 g/L、水深0.25 m、常温25 ℃下超声吹脱60 min后氨氮脱除率达到了97%以上,比普通曝气吹脱提高了40%左右; 当废水在磁场强度0.27 MT,预磁化时间10 min后,在同等条件下吹脱60 min时氨氮去除率为99.99%,相对于未经磁化的废水脱除率提高了4%左右。
Abstract:
A compound ammonia stripping agent was made to treat the ammonia nitrogen wastewater by introducing the ultrasonic field and magnetic field, and the optimum conditions of reaction were studied. The results showed that, the concentration of wastewater was
