液膜法去除萃余液中氨氮的试验研究

Study on the Treatment of Ammonia-Nitrogen Wastewater in Emulsion Liquid Membrane

介绍了液膜法处理某湿法厂高浓度氨氮废水的处理工艺,萃余液氨氮废水(NH3-N>500mg/L)经液膜法处理后,出水NH3-N浓度<15mg/L,无二次污染。

This article introduced the technique of removing ammonia from wastewater in emulsion liquid membrane,the results showed that when the initial concentration of ammonia > 500 mg/L under room temperature,the ammonia in treated wastewater was lower for 15 mg/L,and no secondary pollution factors.
