FIELD: water treatment.
SUBSTANCE: invention relates to the mechanical treatment of wastewater and can be used for the treatment of domestic and industrial waste. Grid 2 for sewage treatment from mechanical impurities is made of a metal rod in the shape of a wound truncated cone and contains the sediment-collecting movable mechanism 5. Sediment collecting mechanism 5 is made in the form of a scraper with teeth, pressed laterally to the grid 2. Grid 2 is made with the possibility of vertical axial compression.
EFFECT: invention allows to simplify the design of the grid, to reduce the intensity and increase the reliability of the structure.
