FIELD: sewage water purification.
SUBSTANCE: device comprises separator 1 widening upwards and having inclined outer walls 2. Separator 1 interior defines separation space having lower part with inlet orifice 5 for liquid with suspension delivering and upper part having means 4 for suspension-free liquid removal. Separation space inside separator 1 expands in upward direction in one area over inlet orifice 5 and below silt layer 14 and is defined by outer walls 2. At least one area for excessive concentrated suspension removal is created at said expanded area near one side wall 2 in separation space of separator. Concentrated suspension flows down as solid streams along inclined outer boundary of fluidized silt layer. Said area includes perforated accumulation pipe 3, orifices 7 for excessive concentrated suspension removal and discharge pipe 11 for compressed air.
EFFECT: improved separation ability and increased economical efficiency.
