The invention relates to an integrated treatment method of a chemical flooding produced emulsion. The crude oil treatment flow and the sewage treatment process are integrated to optimize oil and water treatment equipment, an adaptive comprehensive treatment agent and a functional treatment agent are selected, a dosing position is reasonably laid, and the chemical flooding emulsion is transferred and treated in the oil and water integrated treatment flow, so that the water content of transported crude oil reaches 0.6%, the oil content of transported sewage is 9.3mg/L, the suspended solid content is 8.0mg/L, the polymer content is 242mg/L, and the retention rate of polymer-bearing sewage polymer is more than 95%, and thereby avoiding the generation of aging oil and polymer-bearing sludge.
