Abstract
A small sewage treatment plant comprises a first sewage tank in which a preliminary clarification takes place due to the sinking of solid particles to the bottom of the first sewage tank, and a filtering device in a second sewage tank, which filtering device comprises several filters and to which the pre-clarified sewage is fed from above for further clarification. The filtering device has a rotary plate which is rotatable about a vertical axis of rotation and stores several filter containers, each filter container including several filters arranged above each other. In a lid of the second sewage tank, a closable tank opening is provided, via which at least one filter is removable when the associated filter container is opposite to the tank opening after a corresponding rotation of the rotary plate.
