PROBLEM TO BE SOLVED: To provide a method by which the content of water in sludge as industrial waste is efficiently reduced, and its conveyance efficiency to a final treatment place can be increased. SOLUTION: In the dry treatment method, sludge 3 is laid from one end of a drying bed 1 and is exposed to sunlight, thereafter, a self-propelling agitation means 4 is introduced into the other end of the drying bed 1, and while digging up the sludge 3, it is moved to the other end side of the drying bed 1. Thereafter, sludge 3 is further laid on a space formed by the movement. Then, after the repetition of the digging up and movement of the sludge by the self-propelling agitation means and the charge of new sludge, the moved sludge which remains at the farthest position and in which the content of water reaches a desired one is successively carried out from the drying bed 1.
