磁化/超声吹脱处理高质量浓度氨氮废水试验研究
Research of Treating High Concentration Ammonia Nitrogen Wastewater by Magnetization and Ultrasound Stripping
摘要
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 was1 910 to 2 000mg/L,when pH was 11,additive dosage was 0.084 8g/L,the depth was 0.25m,temperature was 25℃ and ultrasonic stripping time was 60min,the ammonia nitrogen removal rate was more than 97%,compared with the traditional air stripping,the ammonia nitrogen removal rate was increased by about 40%.When the wastewater was magnetized under the following condition,the magnetic field strength was 0.27MT and the magnetization time was 10min,the ammonia nitrogen removal rate was 99.99% at the same condition; compared with the un-magnetized wastewater,the removal rate increased by about 4%.关键词
