一种新型聚磷腈离子交换膜制备与污水处理应用研究

Study on preparation of a new type of ion exchange membrane and its application in wastewater treatment

成功合成了一种新型全氟磺酸型聚磷腈离子交换膜。将该膜作阳离子交换膜对污水进行电渗析处理,废水的氨氮浓度从3955mg/L降低到105mg/L,下降了约97.3%,具有较好的去除效率。

A novel type of polyphosphazene with perfluoroalky sulfonic acid group was synthesized and prepared to ion exchange membrane.The membrane was used as anion membrane in electrodialysis device for sewage treatment.After the process by the membrane,the concentration of ammonia nitrogen in wastewater decreased by about 97.3%,from3955mg/L to 105mg/L.This result showed a good removal efficiency.
