FIELD: technological processes. ^ SUBSTANCE: according to invention, at the first stage sewage is fed to silt granules, afterwards these silt granules undergo fluidisation in the presence of oxygen-containing gas, and the third stage (sedimentation stage) involves silt granule sedimentation. At the first stage sewage is fed at a rate preventing layer fluidisation, and at the third stage silt granules form silt granule layer after sedimentation. ^ EFFECT: possibility of efficient removal of organic nutrient substances, nitrogen compounds and phosphate in relatively restricted reactor space. ^ 4 cl, 2 dwg, 1 tbl, 1 ex |
