Example Embodiment
[0029] Example 1
[0030] Select copper acetate, zinc acetate, and silver nitrate as metal ion sources, soak 200g diatomaceous earth in 1L mixed solution of 80g / L copper acetate and 80g / L zinc acetate, stir and absorb at 80℃ for 4h, slowly add 0.1g / L of silver nitrate solution is dropped into the mixed solution, then filtered and dried to obtain modified porous material powder for use.
[0031] Mix according to the ratio of activated carbon: modified porous material powder: binder = 50%: 30%: 20%, mix thoroughly in a high-speed mixer for 4 hours, and place in a 150 ℃ oven to bake for 4 hours. The dried material Pour into the feeding port of the screw extruder, adjust the three-stage heating temperature of the screw extruder to: 150℃, 350℃, 350℃, adjust the extrusion speed to 50rpm, and extrude into a hollow after high temperature and high pressure treatment by the screw extruder Columnar body, cut the filter element according to the required length.
Example Embodiment
