FIELD: instrument making.

SUBSTANCE: invention relates to purification of sewage with various types of impurities and can be used for purification of industrial outfalls. Proposed device comprises casing with intake sewage intake branch pipe and filtrate discharge branch pipe, perforated baffle and filtration element. Said casing represents rigid skeleton made from several vertical U-like flat steel loops arranged in symmetry about device axis on aforesaid baffle and elongated along device length. Said loops are jointed together by several different-diametre rings secured in horizontal plane at device several heights and passing through and out of every U-like loop. Device filtration elements represent one-piece cover fitted on rigid skeleton and secured at device top part, below disk-baffle and at central (in height) part. Said cover comprises internal and external sorption-filtration layers, while thickness of internal sorption-filtration layer matches up with that of external layer as 1:13.
