Preparation method of inorganic porous ceramic membrane
The invention relates to a preparation method of an inorganic porous ceramic membrane. The preparation method includes the following steps: weighing, namely weighing raw materials, a pore former and a sintering aid according to a certain proportion, and mixing them; wet-grinding and dry-grinding a mixture; pelleting a resulting product; performing compression moulding forming; sintering a formed product. Made ceramic has the advantages of large flux, high compressive strength and high reproducibility, and the ceramic membrane is uniform in porosity; the inorganic porous ceramic membrane has the advantages of resistance to high temperature and acid and alkali corrosion, high compressive strength, high reproducible utilization rate and freeness of secondary pollution. Rates of removing COD, oil and suspended solid in water are 82.3%, 85.3% and 89.6% respectively, and good deoiling effect can be realized. A modified ceramic membrane is back-washed under a washing condition of 0.05MPa for reproduction, and clean water flux of the modified ceramic membrane can be restored to 94.7%.
