<p>The invention concerns a waste water treatment plant comprising a container-like thick substance separator (1). In order to develop an overall more compact plant, the following features are proposed: a) provided in the container wall (2), preferably on opposite sides, are a waste water inlet (3) for a waste water pipe (4) which can be connected thereto, and a rinsing water outlet (5) for the pre-treated water; b) a lower container section (6) comprises a settling region for thick substances and settled substances; c) the base (7) of this settling region takes the form of a sump for a solids pump (8); d) mounted in the upper region of the container is a removable pot-shaped drainage insert (9) whose base (10) has screening apertures (11); e) provided on the base (10) of the drainage insert (9) is a screen (13) which is disposed concentric to and at a clear spacing from the insert wall (12); f) the annular drainage duct formed between the screen (13), insert wall (12) and insert base (10) is filled with a filter mass (14) consisting of natural materials, in particular chippings; g) the insert base (10) has an outlet opening (16), which is open towards the insert interior and is connected to the pump pressure line (15), and a baffle plate (17) which is aligned with this outlet aperture (16), lies at a clear spacing above the insert base (10) and is used to deflect the pumped-up solids suspension; and h) the thick substance separator (1) can be closed at the top by a container cover (21) which, to allow the container interior to breathe, has an aperture (22) in which a bio-aeration filter (23) is provided.</p> |
