Ternary composite filter rod containing porous starch granules

The utility model discloses a ternary composite filter rod containing porous starch granules. The ternary composite filter rod comprises a filter element (1) and is characterized in that the filter element (1) is a ternary composite filter element and is formed by connecting a grooved acetate fiber section (11), a porous starch granule section (12) and a grooved acetate fiber section (13) sequentially; the ternary composite filter rod takes the filter element (1) as a core; an inner wrapping layer (2) and an outer wrapping layer (3) are sequentially wrapped outside the filter element (1) from inside to outside; and the inner wrapping layer (2) is wrapped outside the filter element (1), and the outer wrapping layer (3) is wrapped outside the inner wrapping layer (2) and is positioned at the outermost layer of the composite filter rod. Compared with the prior art that a single grooved filter rod is adopted, the ternary composite filter rod has the advantages that the porous starch granules as a novel adsorption
