Bioreactor with moving carriers

Abstract

The invention relates to a bioreactor having a tank (1) with at least one bioreactor compartment (1a-1c) containing a carrier medium, on the surface of which a biofilm may grow, supply means for supplying the water to be purified into the bioreactor compartment (1a-1c) from the first longitudinal end of the compartment, discharge means at the second opposite longitudinal end of the compartment (1a-1c) for discharging the processed water from the compartment, means (7) for supplying the reaction gas required for the purification process into the bioreactor compartment, and means for agitating the carrier medium and the water to be purified into a rotary motion inside the compartment. In the bioreactor compartment (1a-1c), extending in its longitudinal direction, is arranged a perforated pipe (4), which is at a distance from the inner walls (8, 9) of the bioreactor compartment, and in the inlet end area of which pipe (4) are guide means (2a-2c, 13a-13c) for guiding the water to be purified into a bioreactor space outside the pipe (4), from which space the purified water enters inside the perforated pipe (4) and discharges from it through the outlet at the outlet end of the bioreactor compartment (1a-1c).
