<p>The invention relates to a mechanico-biological waste water purifying plant. The plant has a trough and at least one partially immersible rotatable body arranged therein, the body having a stack of discs which are partially immersed in waste water in the trough and a shaft projecting at its end beyond the stack of discs. The ends of the shaft are supported rotatably in the bearings which have at least two bearing rollers upon which the ends of the shaft are positioned so as to be liftable upwards freely therefrom.</p> |
