Useful model relates down the systems for the biological purification of sewages with the use of an active silt, in particular, to the installations, used for cleaning of everyday sewerage drains from the cottages and out-of-town houses of in the absence centralized system. The compact two-section installation for the biological purification of waste water, which is characterized by the increased reliability, by longevity and by the lowered energy consumption of the elements of construction with the operation, that ensures the highly effective, controlled and controlled process the stonecrops of effluents, is executed in the form the monoblock, which is the sunk beside the earth capacity, divided by partition beside two sections, carrying out functions of the receiving reservoir, supplied for the sake of means for the supply of effluents and their subsequent supply beside the activation reservoir, and the activation reservoir, supplied for the sake of means for the supply of air and outlet of purified water and excess silt, moreover means for the supply to liquid from the receiving reservoir beside the activation reservoir, the means for the outlet of purified water from the activation reservoir and the means for the outlet of excess silt from the activation reservoir back beside the receiving reservoir they are executed in the form three air bubble pumps - airlifts, means for the supply of air beside the activation reservoir - in the form dual aerator, located before the bottom-dwelling part of the activation reservoir; moreover airlifts and aerator are united beside the united block of intermittent aeration, connected down the compressor, connected with the microprocessor control unit with the possibility of the start of magnetic valves in accordance with the predetermined program of the supply of the compressed air in activation reservoir. Moreover compressor, microprocessor control unit and magnetic valves are made remote from reservoir. Polyethylene is used as the material for preparing the capacity. 2 heads p. of formula, 1 Fig.
