To provide a treatment method of dredged soil from a sea bottom which can stably perform treatment processes for washing and dehydrating fine granular soil separated from the dredged soil from a sea bottom.
Treated fine granular soil 7 capable of being used as a cement raw material is obtained by carrying out a wet storage process for supplying fine granular soil 6 obtained by classifying the dredged soil 5 from a sea bottom by a classification apparatus 2 to a storage tank 3 in which water of a volume capable of forming a water surface is made to exist, and a fine granular soil treatment process for taking out the fine granular soil from the storage tank 3 in the wet storage process, and dehydrating the fine granular soil by dehydration equipment 4.
