PURPOSE: A compression dehydrator for waste is provided to enhance dehydration efficiency by automatically controlling a compressive force of a compression screw according to the strength of an object when compressing all kinds of wastes. CONSTITUTION: A compression dehydrator for waste comprises: a waste gate(10); a first compression screw pipe(20) which is installed on the lower part of the waste gate and includes a first compression screw; a second compression screw pipe(30) which is connected to the outer circumference of the first screw pipe and includes a second compression screw; a compression piping(40) compressing the waste through the movement of the second compression screw; a compression control shaft(50); a stopper plate(60) including a circular hole; a stopper which is fixed to the end of the second compression screw through the circular hole of the stopper plate; a filter which is installed between the second compression screw and the compression piping; and a drive motor(90') driving the first compression screw and the second compression screw.
