FIELD: sewage treatment practice. SUBSTANCE: method involves settling sewage, filtering it and sorbing on filtering bed. Novelty of the method is in that settling process is conducted at rate 2-4 mm/s, while filtering and sorption are conducted at the following relationship between diameters and heights of bed-constituting layers: D₁/D₂=0.21-1.3 and H₁/H₂=2.3-6.8.
