The device comprises a reservoir divided into a plurality of sections by means of an intermediate base plate (9), a first partition (13) and a second partition (19). A first section (A) comprises a wall (11) for solids and a wall (12) for floating matter in order to separate floating matter and coarse matter. A second section (B1) comprises a screen member (15) and filtration panels (16, 17, 18) for fine filtration. A further section (B2) comprises bag filters (21) for extra-fine filtration of the pollutants in the polluted liquid. A final section (C) comprises a filtering material (26) for adsorption, absorption or chemical conversion of the pollutants dissolved in the liquid.
