In-situ treatment equipment and method for preventing pollutant diffusion during soil remediation

The invention provides in-situ treatment equipment and method for preventing pollutant diffusion during soil remediation, and belongs to the technical field of soil treatment. Comprising an in-situ supporting assembly, and an insertion treatment assembly and an in-situ barrier membrane assembly which are arranged on the in-situ supporting assembly, a mounting platform is arranged at the upper end of the main supporting column, the auxiliary supporting frames are evenly arranged on the outer wall of the bottom end of the main supporting column in the circumferential direction, the inserting-connection blocking frames are connected with the side walls of the auxiliary supporting frames in a one-to-one correspondence mode, and the contaminated soil part between every two adjacent inserting-connection blocking frames forms a plurality of treatment areas; according to the method, the polluted soil can be divided into a plurality of treatment areas, and then the impermeable films are arranged between the adjacent t
