The invention discloses a method and equipment for simultaneously inspecting a plurality of liquid substances by using dual-energy computed tomography (CT). The method comprises the following steps of: performing dual-energy CT scanning on inspected liquid substances at a plurality of positions to acquire dual-energy CT protection data; performing CT reconstruction according to the projection data to acquire the CT images for representing physical attribute values of the inspected liquid substances; rotating the CT images of the inspected liquid substances after performing the dual-energy CT scanning at each position so as to align the images formed by multiple times of scanning operation; extracting the physical attribute values of the inspected liquid substances according to the CT images; and judging whether the inspected liquid substances are dangerous substances based on the physical attribute values. By the method, the liquid substances can be inspected rapidly.
