Preparation method of antibacterial ceramic membrane
The invention relates to the technical field of separation membrane materials, in particular to a preparation method of a bacteriostatic ceramic membrane. According to the preparation method, N, N-diethyl-3-(trimethoxysilyl) propylamine is grafted to the surface and pore walls of a ceramic membrane through a covalent bond, then 1, 4-butane sultone is grafted through a quaternization reaction, and a zwitterionic antibacterial functional layer is prepared on the surface and pore walls of the ceramic membrane. The antibacterial ceramic membrane prepared by the method has the advantages of simple preparation process, mild preparation conditions, remarkable antibacterial effect, no influence on the porosity of the ceramic membrane, no damage to the substrate of the ceramic membrane and the like, and can be widely applied to the field of membrane biological reaction for domestic sewage treatment.
本发明专利涉及分离膜材料技术领域，具体为一种抑菌型陶瓷膜的制备方法。本发明通过共价键接枝N,N‑二乙基‑3‑(三甲氧基硅烷基)丙胺到陶瓷膜表面和孔隙壁上，然后通过季铵盐化反应接枝1,4‑丁烷磺酸内酯，在陶瓷膜表面和孔隙壁上制备两性离子化的抑菌功能层。该方法制备的抑菌型陶瓷膜，制备工艺简单、制备条件温和、抑菌效果显著、不影响陶瓷膜的孔隙率、不损伤陶瓷膜的基底等优点，可广泛应用于生活污水处理的膜生物反应领域。
