Dredged soil soluble salt removal test method

The invention relates to the technical field of ecological environmental protection, and discloses a dredged soil soluble salt removal test method. The method comprises the following steps: (1) pretreating dredged soil; (2) mixing and stirring the pretreated dredged soil and a solvent, and testing the obtained first mixed material according to a test index; (3) dehydrating the first mixed material, testing the moisture content of the separated solid-phase component, mixing and stirring the separated solid-phase component and the solvent, and testing the obtained second mixed material according to the test index; (4) when the obtained second mixed material is higher than an expected value, repeating the step (3) until the second mixed material is lower than the expected value; wherein in the steps (2) and (3), the test indexes comprise the salt content. According to the technical scheme, theoretical support is provided for resource utilization of the dredged soil, and the salt content of the dredged soil is re
