<p>The useful model relates to a facility for biological treatment of waste water, specifically of faecal water, with compact and simplified design. It consists of activation treatment tank (1) with inlet (2) for contaminated waste water, in which an aerator (4) and longitudinal sedimentation (deposit) tank (5) with collector channel (6) and outlet (7) of the treated water are situated. In the longitudinal sedimentation (deposit) tank (5) with width-length ratio higher than 1:2, there is at least one inlet (8) for the mixture of treated water and slurry from the activation treatment tank (1) of the longer side of the longitudinal sedimentation (deposit) tank (5) and the collector channel (6) on the opposite longer side of the longitudinal sedimentation (deposit) tank (5). The inlet (8) for the mixture of treated water and slurry from the activation treatment tank (1) can be through an opening in the longer side of the longitudinal sedimentation (deposit) tank (5) and/or opening in the longer side of the longitudinal sedimentation (deposit) tank (5) for the inlet (8) of the treated water and slurry from the activation treatment tank (1) can be created by decreasing the height of the wall of the longitudinal sedimentation (deposit) tank (5) below the level of the mixture from treated water and slurry in the activation treatment tank (1).</p> |
