摘要
对吹脱法处理稀土氯铵废水进行了研究,分别考察了温度、pH值、气液比、吹脱时间对实验的影响。结果表明,在最佳实验条件下,氨氮的去除率可达到98%以上。用硫酸吸收了尾气,实现了资源回用,避免了二次污染。
The blow-off method for treating rare-earth ammonia chloride wastewater had been studied in the experiment.The influence factors included temperature,pH value,gas-liquid ration and blow-off time,had been investigated.Under the best experimental conditions,the ammonia-nitrogen removal rate could above 98%.The off-gas was imbibed by the sulphuric acid.
