FIELD: ecology; engines and pumps.SUBSTANCE: invention relates to structural elements of plants for biological treatment of domestic waste waters using water-sludge mixture. Air lift includes portion of “compressed air feed pipeline” and “liquid feed pipeline” parts having adapter between each other, which internal channel connects cavities of these pipelines sections to make air supply pipeline into area of its supply, and in part of “liquid feed pipeline” is mixing zone of fluid with air. At that, part of internal channel of adapter is made in form of truncated cone oriented with top to part of liquid supply pipeline cavity.EFFECT: airlift higher reliability, longer life, increased fail-safe operation of domestic sewage effluents biological treatment plants.1 cl, 1 dwg |
