Abstract
Description
Die Erfindung betrifft einen Spülrechen zum Zurückhalten von Stoffen im Mischwasser bei Regenentlastungen in Mischwasserkanälen, insbesondere in Regenüberläufen und Beckeneinläufen. Aus wirtschaftlichen und technischen Gründen ist es notwendig, in Mischwasserkanälen Regenentlastungen vorzusehen. Ein Teil des Mischwassers wird dabei von einem Regenüberlaufbauwerk aus direkt zur Kläranlage weitergeleitet, während die größere Wassermenge über ein Regenüberlaufbecken zur Kläranlage geführt oder vom Regenüberlaufbauwerk aus direkt in ein Gewässer eingeleitet wird. Wird die Entlastungswassermenge direkt dem Gewässer zugeführt, ist es besonders wichtig, dieses Mischwasser von den nicht gelösten Schmutzstoffen weitestgehend zu befreien. Gegenwärtig wird das Mischwasser in den meisten Fällen ohne Zwischenschaltung eines Regenüberlaufbeckens direkt in den Vorfluter abgeleitet. Dieses Wasser durchfließt keine Rechenanlage, so dass die Schmutzfracht, die in das Gewässer gegeben wird, sehr hoch ist. Der Einbau eines Rechens wurde bisher aus Kosten- und Wartungsgründen unterlassen. In den Einzelfällen, in denen das Mischwasser vor Einleitung in den Vorfluter in einem Regenwasserklärbecken grobmechanisch gereinigt wird, können die ungelösten Schmutzstoffe zwar zu einem großen Teil zurückgehalten werden, die Entfernung der Stoffe aus den großflächigen Beckensohlen gestaltet sich jedoch schwierig. Oft bleiben diese Stoffe längere Zeit in den trockenen Becken liegen. Geruchsbelästigungen sind die Folge.The invention relates to a rinsing rake for holding back substances in the mixed water when rain is discharged in mixed water channels, in particular in rain overflows and basin inlets. For economic and technical reasons, it is necessary to provide rain relief in mixed water sewers. A part of the mixed water is conveyed from a rain overflow structure directly to the sewage treatment plant, while the larger amount of water is conducted via a rain overflow basin to the sewage treatment plant or is discharged directly from the rain overflow structure into a body of water. If the discharge water is fed directly into the body of water, it is particularly important to remove the undissolved pollutants from this mixed water as far as possible. In most cases, the mixed water is currently discharged directly into the receiving water without the interposition of a rain overflow basin. This water does not flow through any computer system, so that the pollution load that is given into the water is very high. The installation of a rake has so far been omitted for reasons of cost and maintenance. In individual cases in which the mixed water is roughly mechanically cleaned in a rainwater clarification basin before it is discharged into the receiving water, the undissolved pollutants can be retained to a large extent, but the removal of the substances from the large-area basin floors is difficult. Often these substances remain in the dry basin for a long time. The result is unpleasant smells.
Der Erfindung liegt die Aufgabe zugrunde, insbesondere für Regenüberläufe und Beckeneinläufe in Mischwasserkanälen eine automatisch und wartungsfrei arbeitende Rechenanlage zu schaffen.The invention is based on the object of creating a computer system that works automatically and maintenance-free, in particular for rain overflows and basin inlets in mixed water channels.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das gegen den Rechen fließende Mischwasser die an die Rechenblätter stoßenden Stoffe mit einer Abwärtsströmung in eine zur Kläranlage weiterführende Leitung befördert und das Überlaufwasser weitestgehend frei von solchen Stoffen ist.This object is achieved according to the invention in that the mixed water flowing against the rake conveys the substances hitting the rake with a downward flow into a line leading to the sewage treatment plant and the overflow water is largely free of such substances.
Die mit der Erfindung erzielten Vorteile bestehen darin, dass das von den Regenüberläufen ins Gewässer bzw. in die Regenüberlaufbecken fließende Mischwasser weitestgehend von den ungelösten Stoffen befreit wird und somit eine unnötige Belastung der Vorfluter unterbleibt bzw. die umständliche Entfernung der Stoffe aus den großflächigen Sohlen der Regenüberlaufbecken wegfällt und das erforderliche Abpumpen des Mischwassers aus diesen Becken störungsfrei möglich ist.The advantages achieved with the invention are that the mixed water flowing from the rain overflows into the water or into the rain overflow basin is largely freed of the undissolved substances and thus an unnecessary burden on the receiving waters or the laborious removal of the substances from the large floors of the There is no rain overflow basin and the necessary pumping out of the mixed water from these basins is possible without any problems.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the invention is shown in the drawing and is described in more detail below:
Aufbau der Erfindung:Structure of the invention:
In ein Regenüberlauf- bzw. Beckeneinlaufbauwerk 1 ist ein gegen die Fließrichtung geneigter Rechen 2 aus verzinkten Stahlblechblättern angeordnet, der oben an einem senkrechten Staublech 3 und unten an einem Abdeckblech 15 endet, das auf einem Führungskasten 16 aus Beton aufliegt. Der Führungskasten 16 ist an eine Ablaufleitung 17 aus Stahl angeschlossen. Unter der Ablaufleitung 17 befindet sich eine Ablaufkammer 18, von der eine Entlastungsleitung 19 abgeht.In a rain overflow or basin inlet structure 1, a rake 2 inclined against the direction of flow is arranged from galvanized sheet steel sheets, which ends at the top on a vertical baffle 3 and at the bottom on a cover plate 15 which rests on a guide box 16 made of concrete. The guide box 16 is connected to a drain line 17 made of steel. Under the drain line 17 there is a drain chamber 18 from which a relief line 19 branches off.
Wirkungsweise der Erfindung:Mode of operation of the invention:
Die mit dem Mischwasser ankommenden Stoffe stoßen gegen den Rechen 2 und werden in einer Abwärtsströmung zwischen den breiten Rechenblättern in einen Führungskasten 16 und weiter in eine zur Kläranlage abgehende Rohrleitung 17 befördert. Das von den störenden Stoffen weitestgehend befreite Mischwasser strömt durch den Rechen 2 und fällt nach Überfließen des Führungskastens 16 in eine Ablaufkammer 18. Von hier fließt es in einer Entlastungsleitung 19 weiter in ein Regenüberlaufbecken oder direkt in ein Gewässer.The substances arriving with the mixed water collide with the rake 2 and are conveyed in a downward flow between the wide rake blades into a guide box 16 and further into a pipeline 17 leading to the sewage treatment plant. The mixed water largely freed of the disturbing substances flows through the rake 2 and, after overflowing the guide box 16, falls into a drainage chamber 18. From here it flows in a relief line 19 into a rain overflow basin or directly into a body of water.
