一种废水处理用陶瓷催化膜及制备方法
摘要：
本发明涉及污水处理领域，公开了一种废水处理用陶瓷催化膜及制备方法。将微孔陶瓷膜预处理后，浸润硝酸铜、硝酸镁的壳聚糖分散液，并通过加入Na2CO3、NaOH，使陶瓷膜的微孔中生成氢氧化铜、氢氧化镁，并利用戊二醛交联处理，通过在隔绝空气环境下焙烧，壳聚糖碳化，在微孔陶瓷薄膜的微孔原位生成由碳网络的氧化铜、氧化镁，其有效防止催化剂流失，并具有与污水、臭氧良好的接触界面，从而提高催化活性。该催化剂能有效辅助臭氧快速分解成羟基自由基，从而将能将废水中的醇、酮、有机酸和酯类等污染物分解。
摘要（英）：

The invention relates to the field of sewage treatment and discloses a ceramic catalytic membrane for treating waste water and a preparation method. The ceramic catalytic membrane is characterized inthat after being pretreated, a microporous ceramic membrane is soaked in chitosan dispersing solution of copper nitrate and magnesium nitrate; by addition of Na2CO3 and NaOH, copper hydroxide and magnesium hydroxide are generated in micropores of the ceramic membrane; crosslinking treatment is carried out by utilizing glutaraldehyde, then the ceramic membrane is roasted without air, and chitosan is carbonized; copper oxide and magnesium oxide networked by carbon are generated in situ in the micropores of the microporous ceramic membrane, the loss of the catalyst is effectively prevented and agood contact interface with sewage and ozone is formed, so that the catalytic activity is improved. The catalyst can assist the rapid decompose of ozone into hydroxyl radicals, so that pollutants suchas alcohol, ketone, organic acid and esters and the like in the waste water can be decomposed.
