Problems solved by technology

[0003] Most of the existing ceramic membranes are porous structures fired from clay, which are not strong enough, easy to be damaged during use and cleaning, and have a short service life
[0004] Moreover, microorganisms in the sewage are easy to multiply in the ceramic membrane, causing the membrane pores of the ceramic membrane to be blocked.

Abstract

The invention discloses a ceramic membrane filter which comprises a sealed housing and a ceramic membrane arranged in the sealed housing. The ceramic membrane comprises a porous blank formed by sintering diatomite, wherein an aluminum oxide layer and nano metal particles containing metal ions are attached to the surface of the porous blank. The invention further discloses a preparation method of the ceramic membrane filter. The ceramic membrane has the function of inhibiting bacterial reproduction, is smooth in surface, high in strength and long in service life and can be repeatedly scoured for usage.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a ceramic membrane filter and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the increasing emphasis on water environment protection, ceramic membrane filters are more and more used in the field of water treatment technology. The sealed shell and the ceramic membrane are two major components of the ceramic membrane filter. The sealed shell is provided with a sewage inlet, a sewage outlet and a clean water outlet. The sewage inlet is connected to one end of the ceramic membrane, and the sewage outlet is connected to the other end of the ceramic membrane. The clear water outlet is arranged on the sealed housing, and is used to discharge the clear water filtered by the ceramic membrane. [0003] Most of the existing ceramic membranes are porous structures fired from pottery clay, which have insufficient stre...
