Abstract

The plant serves for the decontamination of the soil, sludges, rubble or the like, containing pollutants, with the aid of micro- organisms. It comprises at least one approximately cylindrical closable silo tank (1) serving as a bioreactor and intended for the reception and mixing of the materials to be purified, at least at intervals, with the addition of oxygen or air. The circulating motion serving to mix the materials is executed with the aid of compressed air or hydraulic means. A removal opening (3) situated centrally at the lowest point of the silo tank is provided in the conically designed bottom region of the silo tank (1), the said bottom region tapering like a funnel. In order to ensure a controlled circulating motion of the materials in a particularly simple manner, a circulating pump (22) is connected to the removal opening (3), the said pump being connected to the feed opening (2) of the silo tank (1) via a recirculating line (23) carrying the materials back to the top of the silo. <IMAGE>
