<p>Reactor for biological sewage purification with activated sludge with a separation of the activated sludge through fluidized bed filtra- tion, especially for purification of small individual sewage contami- nation sources, e.g. family houses, colonies of them, hotels, smaller housing estates and so on. The reactor for biological sewage purifi- cation containing an activation space and an upwards funnel shape separation space (2) for fluidized bed filtration in the tank. The acti- vation space (4) between the wall (3) of the separation space (2) for fluidized bed filtration and the outer casing (1) of the reactor tank is partitioned by at least one partition (5), wherein the separation space (2) communicates with the activation space (4) through a passage (13), the passage being located in front of the partition (5), and through a recirculation set (8) the suction inlet of which is led to the bottom of the separation space (2) and the outlet in the activation space (4) behind the partition (5).</p> |
