Description

Beschre ibungDescription

Die Erfindung bezieht sich auf eine Mischwasserantlastungs- bzw. behandlungsanlage mit elaem insbesondere weitgehendem Grobstoffnieckhalt. The invention relates to a mixed water discharge or treatment plant with particularly extensive coarse material retention.

Kischwasserentlastungs- bzw· -behandlungsanlagen sind seit dem letzten Jahrhundert bekannt. Kit der Fortentwicklung der Zivilisation wurden auch die Kanalisation und deren Entlastungsbauwerke weiterentwickelt. An mechanischen Kischwasserentlastungs- bzw. -behandlungsanlagen unterscheiden wir heute Segenueberlaeufe, Eegenbecken mit Beckenueberlauf und/oder Klaerueberlauf, Regenrückhaltebecken und Regenklaerbecken. Ein grosser Teil der im Abwasser befindlichen Grcb- und Schwimmsioffe wird zwar in Hegenbecken zurueckgehalten. Dennoch sind dip kurzzeitigen Entlastungen stark belastet, was in den Gewaessern zu optischen Nachteilen fuehrt. Tauchwaende und neuerdings auch Sechen— und Siebanlagen versuchen diese Schmutzstoffe zurueckzuhalten. Water discharge and treatment systems have been known since the last century. As civilization developed, sewage systems and their discharge structures were also further developed. Today, we distinguish between mechanical water discharge and treatment systems: storm overflows, sewage basins with basin overflow and/or sewage overflow, storm retention basins and storm sewage treatment basins. A large proportion of the coarse and floating waste in the wastewater is retained in retention basins. Nevertheless, the short-term discharges are heavily contaminated, which leads to visual disadvantages in the waters. Submersible walls and, more recently, sieves and screening systems try to retain these pollutants.

Ein Nachteil bei den bisher verwendeten Mischwasserentlastungs- bzw. behandlungsanlagen ist, dass sie durch die zeitweilig grossen Entlastungszeugen trotz Tauchwaenden nicht in der Lage sind, die Grob- und Schwimmstoffe zurueckzuhalten. Rechen- und Siebanlagen haben ausserdsm den Sachteii, dass sie wartungsintensiv und teuer sind. Sie verursachen einen relativ grossen hydraulischen Widerstand und sind nicht selbstreinigend.A disadvantage of the combined sewage discharge and treatment systems used to date is that, despite the presence of submersible walls, they are unable to retain coarse and floating materials due to the large discharge devices. Screening and screening systems also have the disadvantage that they are maintenance-intensive and expensive. They cause a relatively high hydraulic resistance and are not self-cleaning.

Der Erfindung liegt die Aufgabe zugrunde, die vorstehend genannten Hachteile bei Kischwasserentlastungs- und -behandlungsanlagen der eingangs genannten Art zu beseitigen und eine Ablage zu schaffen, die einfach in der Herstellung, sicher in der Wirkungsweise und wartungsarm ist.The invention is based on the object of eliminating the above-mentioned disadvantages in cool water relief and treatment systems of the type mentioned at the outset and of creating a storage system which is simple to manufacture, safe in operation and low in maintenance.

Erreicht ist dieses Ziel dadurch, dass das verschmutzte Abwasser ein aus duennwandigen, oben und unten offenen Hohlkoerpern gebildetes Sieb von unten nach oben dürchstroenrfc. Das Sieb ist vorwiegend horizontal angeordnet.This goal is achieved by allowing the contaminated wastewater to flow from bottom to top through a sieve made up of thin-walled hollow bodies that are open at the top and bottom. The sieve is arranged primarily horizontally.

In der Zeichnung, Fig. 1 (Draufsicht) und Fig. 2 (Laengsschnitt), ist der Erfindungsgegenstand in einem Ausfuehrungsbeispiel (Regenueberlaufbecken als Vebundbecken im Nebenschluss mit Becken- (6) und Elaerueberlauf (7) dargestellt. Bei Eegenbeginn fliesst das Abwasser, das nicht mehr van der Klaeranlage (8) aufgenommen werden kann ueber den Zulauf (9) und die Schwelle (10) zunaechst in den Fangteil (11) des Regenbeckens. Von da strcemt es ueber die Recüteckaeffnucg (4) in ««n separaten Beckenteil (3) von unten nach oben durch das aus duennwandigen Hahlkoerpern (1) gebildete Sieb (2). Dadurch wird errei^'.J, dass Grob- und Schwimmstoffe beim Durchstraemen zerkleinert bzw·, am Durchstroemen gehindert werden. Durch die Hoehe (d.h. Laenge der Hohlkoerper) wird ausserdem vermieden, d";>s sich Faserstoffe um das Sieb ochlingen, sowie fuer eine gute Stabilitaet des Siebes gesargt. Hach anschliessendem Durchfluss durch den Klaerteil (12) und Passieren der rohrfoermigen Oeffnungen (5) befindet sich ein weiteres Sieb, durch das Grab- und Schwimmstaffe vom Klaerueberlauf (7) und damit vom Gewaesser (13) ferngehalten werden. Bei gefuelltem Becken und weiterhin starkem Abwasserzufluss (9) wird dann auch Abwasser as Eecksnueberlauf (5) in dss Gevsesser (14) entlastet. Auch hier werden Grob- und Schwimmstoffe zurueckgehalten. Fach Absinken des Wasserspiegels loesen sich die an der Flaeche des Siebes anhaftenden Stoffe und fallen nach unten. Der Abloeseprozess kann durch Abspritzen mit einer kleinen Abwasserpumpe noch verbessert werden. Kaegliche Ausbildungsformen sind als Schnitte in den Fig. 3, 4 und 5 wiedergegeben. Die Groesse der Siebe kann den jeweiligen Anforderungen angepasst werden (z.B. Beckenueberlauf grob und Klaerueberlauf fein), lach Entleerung des Fangteils (11) kann der sauberere Inhalt des Klaerteils (12) als Spue!wasser Verwendung finden (15). Bei R<?ndbecken laesst sich der Klaerueberlauf in gleicher Weise van Grab- und Schwimmstoffen fernhalten (separater Beckenteil var dem Klaerueberlauf als Umlauf)In the drawing, Fig. 1 (top view) and Fig. 2 (longitudinal section), the subject matter of the invention is shown in an exemplary embodiment (storm overflow basin as a combined basin in parallel with basin (6) and water overflow (7). At the beginning of the rain, the waste water that can no longer be taken up by the sewage treatment plant (8) flows via the inlet (9) and the sill (10) first into the catchment part (11) of the storm basin. From there it flows via the rectangle opening (4) into a separate basin part (3) from bottom to top through the sieve (2) formed from thin-walled hollow bodies (1). This ensures that coarse and floating materials are crushed as they flow through or are prevented from flowing through. The height (i.e. length of the hollow bodies) determines the It also prevents fibrous material from growing around the sieve and ensures good stability of the sieve. After the subsequent flow through the clarifier part (12) and passing through the tubular openings (5), there is another sieve that keeps the digging and floating material away from the clarifier overflow (7) and thus from the water (13). When the basin is full and the wastewater inflow (9) continues to be strong, wastewater is also discharged via the corner overflow (5) into the water collector (14). Here, too, coarse and floating material is retained. When the water level drops, the materials adhering to the surface of the sieve come loose and fall to the bottom. The removal process can be further improved by spraying with a small wastewater pump. Possible designs are shown as sections in Fig. 3, 4 and 5. The size of the sieves can be adapted to the respective requirements (e.g. coarse basin overflow and fine clarifier overflow). After emptying the catch section (11), the cleaner contents of the clarifier section (12) can be used as rinsing water (15). In circular basins, the clarifier overflow can be kept free of debris and floating matter in the same way (separate basin section in front of the clarifier overflow as circulation).

Eine erfindungsgemaesse Mischwasserent1astungs- bzw. behandlungsanlage bereitet in dar Herstellung ieine Schwierigkeiten. Der zusaetzliche Kastenaufwand fuer die Siebe und den separaten Beckenteil einschl. Oeffnungen ist relativ gering. Durch das zwangsweise Durchstroemen werden Grob- und Schwimmstaffe gezielt und einfach vom Gewaesser ferngehalten und nahezu selbsttaetig gereinigt.A mixed water discharge or treatment system according to the invention presents no difficulties in its manufacture. The additional cost of the box for the sieves and the separate basin section including openings is relatively small. Due to the forced flow, coarse and floating particles are kept away from the water in a targeted and simple manner and are cleaned almost automatically.
