Embodiment 1
[0025] This embodiment provides a method for treating waste gas in the spraying industry using an ozone catalytic functional ceramic membrane as a catalytic separation material, including:
[0026] A, preparation of ozone catalytic functional ceramic membrane;
[0027] B. Use the ozone catalytic functional ceramic membrane as a catalytic separation material to treat waste gas from the spraying industry.
[0028] preferred, such as figure 1 As shown, the preparation method of ozone catalytic functional ceramic membrane is as follows:
[0029] (1) Pretreatment of substrate ceramic membrane
[0030] The pore diameter of the base ceramic membrane used in the present invention is about 0.1 μm. Before the preparation, the base ceramic membrane was ultrasonically cleaned several times (at least 3 times) with deionized water and ethanol respectively, so as to remove impurities on the surface of the base ceramic membrane. Then put it into a muffle furnace, bake it at 580-600°C for ...
