Integrated emission reduction method based on carbon dioxide capture and utilization

The invention relates to the technical field of carbon dioxide capture, in particular to an integrated emission reduction method based on carbon dioxide capture and utilization. Comprising the following steps: setting working parameters and trapping period duration of a trapping unit according to flue gas parameters in a flue, and setting a storage time node according to the trapping period duration; acquiring carbon dioxide in the trapping unit according to the storage time node, and transporting the trapped carbon dioxide to the storage unit; judging whether the working parameters of the trapping unit are corrected or not according to the carbon dioxide storage amount in the storage unit; by additionally arranging the two sub-trapping parts, carbon dioxide in the flue is alternately trapped, and by arranging the first trapping modules and the second trapping modules in the sub-trapping parts, through chemical adsorption of the first trapping modules and physical adsorption of the second trapping modules, th
