Electric remediation column and electric remediation system for contaminated soil

The utility model discloses an electric remediation column, an electric remediation system and an electric remediation method for contaminated soil. The electric remediation column comprises a column body, at least one pair of plate frames which are correspondingly arranged up and down is fixed on the peripheral wall of the column body, an angle of 0-70 degrees or 110-180 degrees is formed between the plane where the plate frames are located and the horizontal plane, and electrode plates which can form a vertical electric field after being electrified are placed in the framework of the upper plate frame and the framework of the lower plate frame; an annular sleeve frame is fixedly arranged on the peripheral wall of the column body in a sleeving manner; and an electrode plate capable of forming a horizontal electric field after being electrified is placed in a gap formed between the annular sleeve frame and the column body. The electrode plates capable of forming a vertical electric field and the electrode pla
