[0013] 1. The ceramic filter for waste gas treatment is provided with a ceramic filter cartridge 1, an activated carbon filter cartridge and a ceramic filter cartridge 2. When filtering the waste gas, the waste gas is first sent into the interior of the filter body through an air inlet pipe, and the waste gas first enters the ceramic filter cartridge 1 arranged in the interior of the supporting frame 1, and the waste gas is initially filtered by the ceramic filter cartridge 1, and the waste gas passing through the ceramic filter cartridge 1 enters the activated carbon filter cartridge arranged in the interior of the connecting pipe through one end of the connecting pipe, and the waste gas is secondary filtered by the activated carbon arranged in the activated carbon filter cartridge, and the waste gas passing through the connecting pipe is sent into the ceramic filter cartridge 2 arranged on the supporting frame 2 through the other end of the connecting pipe for tertiary filtration, and is discharged through the air outlet pipe arranged at the other end of the filter body after the filtration is completed, thereby completing the tertiary filtration of the waste gas. The arrangement of this structure can effectively improve the degree of purification of the waste gas through three filtrations, reduce the harm of the waste gas to the external atmosphere, and improve the treatment efficiency of the waste gas, thereby solving the problem that the waste gas harms the external atmosphere due to simple filtration in the prior art, and ensuring the safety of the external atmosphere.

[0014] 2.
