Abstract

The installation comprises a basin sunk into the ground and lined with concrete, asphalt, etc. It has a central decantation chamber partitioned from a surrounding, concentric annular chamber for aeration which, in turn, is partitioned from a surrounding, post clarification area. In plan view, the basin presents a contour which is egg-shaped; the inlet end of the basin is a semi-circle concentric with the decantation chamber and the outlet end is exgended with gently curved sides merging with a radiused tip. Pref. the decantation chamber is formed as a funnel with conically tapering sides. Cylindrical partitions bounding the annular, aeration chamber are pref. built up of interlocking, profiled sections of synthetic plastic, partic. PVC extrusions. The oval-shaped surfaces increases the area in contact with atmos. The outlet end sides are easier to construct and maintain than the semicircular end sides. For a given treatment capacity, it is frequently easier to accommodate a longer, narrower basin that a circular one.

Description

Kläranlage:Sewage treatment plant:

Patentanmeldung als Zusatzanmeldung zu P 25 25 909.0 Beschreibung Der Erfindungsgegenstand ist eine Bauweise, Verfahren und ein Bauelementensatz zur Herstellung eines Abwasser-Kläranlage, wie sie sich auf Grund der Ergebnisse der Weiterentwicklung in neuheitlicher und fortschrittlicher Weise ergibt.Patent application as an additional application to P 25 25 909.0 description The subject matter of the invention is a method of construction, a method and a set of components for Manufacture of a wastewater treatment plant as it is based on the results of the Further development in a novel and progressive manner.

Mit dem Erfindungszusatz ist der Baubetrieb noch einfacher, billiger und Boden - unabhängiger, bei noch umfangreicherem Einsatz elastisch einsetzbaren extrudierten Kunststoffprofilen.With the addition of the invention, construction is even easier and cheaper and floor - more independent, flexible to use for even more extensive use extruded plastic profiles.

Der Erfindungsgegenstand ist in beiliegender Zeichnung dem System nach dargestellt.The subject of the invention is the system in the accompanying drawing shown after.

Es zeigen: Fig. 1 der Aufriß der Kläranlage - als Schnitt in der Längsachse.They show: FIG. 1 the elevation of the sewage treatment plant - as a section in the longitudinal axis.

Fig. 2 das Schlammrückführelement Fig, 3 den Querschnitt eines Profilstabes zur Herstellung der Raumteilungs- und Bodenkörper Fig. 4 zu Fig. 3 den Längsschnitt, Jedoch mit Förder-Öffnungen Fig. 5 den Querschnitt einer Variante zu Fig. 3.Fig. 2 shows the sludge return element, Fig. 3 shows the cross section of a profile bar for the production of the space dividing and floor bodies Fig. 4 to Fig. 3 the longitudinal section, However, with conveying openings, FIG. 5 shows the cross section of a variant of FIG. 3.

Die Aufgabe ist im wesentlichen wie folgt gelösts Ein kalpttenförmiger Weiher (1) wird am Standort ausgehoben, der vorzugsweise zum Ablauf (20,21) hin im Längsschnitt erweitert ist, Jedoch im Grundriß sich verengt. Zentral ist die Kalotte (2) mit einem vorzugsweise aus einem Befestigungsteppich 3 aus koppelbaren (24,25) Profilstäben (26,27) abgedeckt. Im Zentrum ist der Raum unterteilt mit einem drehsymmetrischen Mantel (6) aus koppelbaren Profilstäben. Konzentrisch dazu ist ein weiterer vorzugsweise allseits gelrümmter, drehsymmentrischer Mantel (7) eingesetzt.The object is essentially achieved as follows Pond (1) is excavated at the location, preferably towards the drain (20, 21) is expanded in the longitudinal section, but narrowed in the plan. That is central Dome (2) with a preferably from a fastening carpet 3 can be coupled (24.25) profile rods (26.27) covered. In the center the room is divided with a rotationally symmetrical jacket (6) made of connectable profile rods. Is concentric to it a further torsionally symmetrical jacket (7), preferably curved on all sides, is used.

Diese bilden den Vorklärraum und den Belebungsraum.These form the primary clarification room and the activation room.

Die Abwasserzuleitung (4) erfolgt über ein Vertikalrohr (5) mit Schirm (8). Die Schlammrückführung erfolgt über einen Rohrbogen (10) der den Schlamm über (22 nach 23) leitet. Die Stabprofile sind einseitig versetzt (26) durchlöchert, womit die Hohlräume der Profilstäbe zur Wasserstromförderung (11,13,12,14) dienen.The waste water supply line (4) takes place via a vertical pipe (5) with a screen (8th). The sludge is returned via a pipe bend (10) that transfers the sludge (22 to 23) leads. The bar profiles are perforated on one side offset (26), with which the cavities of the profile rods are used to promote water flow (11,13,12,14).

Der Ablauf ist ein Rohr (20) mit Bogen, in dessen Mantel Trockenwetterabflußschlitze (21) angebracht sind. Die Stabprofile haben einen Kartenquerschnitt, der mit jeweils 1 oder 2 Koppelungselementen (24,25) ergänzt ist.The drain is a pipe (20) with an elbow, in the jacket of which has dry weather drainage slots (21) are attached. The bar profiles have a map cross-section that corresponds to each 1 or 2 coupling elements (24,25) is added.

Einbuchtungen in der Wand (29,30) erhöhen die Elastizität im Zusammenbau.Indentations in the wall (29,30) increase the elasticity in the assembly.
