Embodiment 1
[0026] A kind of ceramic ultrafiltration membrane with self-cleaning function, its preparation method is as follows:
[0027] (1) Add 0.1g potassium titanyl oxalate K2TiO(C2O4)2 and 0.1g titanyl sulfate TiOSO4 into a mixed solution of deionized water and diethylene glycol with a total volume of 40mL and a volume ratio of 1:4 to obtain a mixed solution I, add 1g urea and 1.5mL concentrated hydrochloric acid again, after fully stirring, put into the autoclave that volume is 50mL, obtain mixed solution II.
[0028] (2) Put the flat-type alumina micron filter membrane with a size of 2cm×3cm into the autoclave, and conduct a hydrothermal reaction at 220°C for 27.5 hours; after the reaction, take out the wet product of the flat-type alumina micron filter membrane with the nano-layer attached , cooled, rinsed with deionized water, and then dried at 80°C for 2 hours to obtain a ceramic membrane support with nano-layers attached.
[0029] (3) Put the ceramic membrane support with the ...
