Zusammenfassung:	The utility model discloses a polluted soil sample preparation device, which comprises a saturation cylinder (1) with a sealing cover (12), and a vacuum pump (2) and a liquid storage container (3) which are respectively connected with the saturation cylinder (1), the saturation cylinder (1) is divided into a plurality of cavities (11) by partition plates (13), a multi-way valve (6) is arranged in the middle of the sealing cover (12), one end of the multi-way valve (6) is communicated with the liquid storage container (3), and the other end of the multi-way valve (6) is communicated with the liquid storage container (3). And the other ends of the air inlets (2) are communicated with the chambers (11) one by one through pipelines (7). According to the utility model, the saturation cylinder is divided into a plurality of chambers by the partition plates, so that vacuum saturation can be carried out on soil bodies with different pollutants and pollution concentrations at the same time, the time for subsequently r
