Abstract
Description
Die Erfindung beschreibt eine wartungsfreie Regenwassernutzungsanlage, bestehend aus Zisterne mit zugehöriger Installation, Regenwasser-Reinigungsweiche und Steuerung, deren besonderes Leistungsmerkmal das Einhalten einer vom Betreiber für die Zisterne vorgegebenen Wasserqualität ist. Daneben erlaubt eine derartige Anlage die Installation einer Zisterne unterhalb des Niveaus des örtlichen Kanalsystems, d. h. ein Anschluß der Zisterne an das Kanalsystem ist nicht erforderlich.The invention describes a maintenance-free rainwater utilization system consisting of Cistern with associated installation, rainwater cleaning switch and control, their A special feature is the compliance with a given by the operator for the cistern Water quality is. In addition, such a system allows the installation of a cistern below the level of the local sewer system, d. H. a connection of the cistern to the Channel system is not required.
Auch beim Betrieb einer Regenwassernutzungsanlage unter Verwendung einer sog. Regenwasser-Reinigungsweiche (wie unter P 42 02 245.2 beschrieben) gelangt Regenwasser mit festen Bestandteilen (Trübung) in die Zisterne. Diese Trübung führt im Laufe der Zeit zu Schlammablagerungen auf dem Behälterboden, die sich inbesondere bei geringem Wasserstand und dadurch erforderlichem Frischwasserzulauf (aus dem öffentlichen Netz in die Zisterne) in einer extremen Verschlechterung der Wasserqualität an der Entnahmestelle bemerkbar machen.Even when operating a rainwater harvesting system using a so-called Rainwater cleaning switch (as described under P 42 02 245.2) gets rainwater with solid components (turbidity) in the cistern. This cloudiness leads to over time Sludge deposits on the bottom of the tank, especially when the water level is low and the required fresh water supply (from the public network to the cistern) in an extreme deterioration in water quality at the point of use.
Insbesondere ist beim Erstbetrieb einer Regenwassernutzungsanlage, bei der mittels Frischwasserzulauf ein Mindestwasserstand in der Zisterne hergestellt wird, eine vorherige Reinigung der Zisterne (ausspülen und abpumpen) erforderlich.In particular, when using a rainwater harvesting system for the first time Fresh water supply a minimum water level is established in the cistern, a previous one Cistern cleaning (rinse and drain) required.
Dem Problem des Verschlammens wird bei der Installation von Zisternen dadurch begegnet, daß die Ansaugstelle zur Entnahme des Regenwassers ca. 10 cm über dem Behälterboden liegt. Spätestens beim Zuführen von Frischwasser bei Niedrigwasserstand wird jedoch diese Maßnahme wirkungslos.The problem of sludge is addressed when installing cisterns by that the suction point for removing the rainwater is approx. 10 cm above the bottom of the container. However, at the latest when fresh water is supplied at a low water level, this becomes Measure ineffective.
Die unter P 42 27 020.0 beschriebene "Anschlußeinheit mit automatischem Frischwasserzulauf für Regenwasser-Zisternen" löst zwar das Problem der Vermischung von verschmutztem Restwasser mit zugeführtem Frischwasser, verhindert jedoch nicht das Bilden von Schlammablagerungen.The "connection unit with automatic fresh water supply described under P 42 27 020.0 for rainwater cisterns "solves the problem of mixing the dirty Residual water with fresh water supplied, however, does not prevent the formation of Sludge deposits.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die vorstehend genannten Nachteile zu beseitigen.The present invention is therefore based on the object, the aforementioned Eliminate disadvantages.
Erfindungsgemäß wird diese Aufgabe, wie in Bild 1 dargestellt, dadurch gelöst,According to the invention, as shown in Figure 1, this object is achieved by
- - daß mit einer sog. Regenwasser-Reinigungsweiche (1, 2) (wie unter P 42 02 245.2 beschrieben) nur Regenwasser einer definierten Qualität in die Zisterne (14) geleitet wird, Regenwasser schlechterer Qualität also in die Kanalisation (9) abgeleitet wird,- that with a so-called rainwater cleaning switch ( 1 , 2 ) (as described under P 42 02 245.2) only rainwater of a defined quality is led into the cistern ( 14 ), rainwater of poorer quality is thus discharged into the sewage system ( 9 ),
- - daß die Wasserqualität der Zisterne dadurch sichergestellt wird, daß vom Zisternen-Boden periodisch (z. B. in niederschlagsfreien Zeiten) Wasser abgesaugt und dem Zulauf (13) der Regenwasser-Reinigungsweiche (1, 2), durch den üblicherweise das Dachablaufwasser (11) einströmt, zugeführt wird; dieser Vorgang kann sofort dann beendet werden, wenn die Qualität des so der Regenwasser-Reinigungsweiche zugeführten Zisternenwassers die Einleitung in die Zisterne erlaubt, - That the water quality of the cistern is ensured by the fact that water is sucked off periodically (e.g. during periods without precipitation) and the inlet ( 13 ) of the rainwater cleaning switch ( 1 , 2 ), through which the roof drain water ( 11 ) flows in, is supplied; this process can be ended immediately if the quality of the cistern water supplied to the rainwater cleaning switch allows it to be discharged into the cistern,
- - daß der Regenwasserzulauf (10) zur Zisterne vollständig von der Regenwasser- Reinigungsweiche (1, 2) kontrolliert werden kann, indem z. B. auch der Zustand "Zisterne voll" von der Reinigungsweiche in ein Ableiten des Dachablaufwassers in die Kanalisation (9) umgesetzt wird,- That the rainwater inlet ( 10 ) to the cistern can be completely controlled by the rainwater cleaning switch ( 1 , 2 ) by z. B. the state "cistern full" is converted from the cleaning switch into a drainage of the roof drain water into the sewage system ( 9 ),
- - daß das zum Zweck der Qualitätssicherung in die Reinigungsweiche notwendige Fördern des Zisternenwassers auch über das Hauswasserwerk erfolgen kann (d. h. während der Kontrollphase des Zisternenwassers kann dann kein Zisternenwasser an andere Verbraucher abgegeben werden),- That the conveyance necessary for the purpose of quality assurance in the cleaning switch of the cistern water can also take place via the domestic waterworks (i.e. during the Control phase of the cistern water can then no cistern water to others Consumers are given),
- - daß die Inbetriebnahme der Anlage vollautomatisch erfolgen kann, indem das zum Erreichen eines Mindestwasserstandes in der Zisterne zugeführte Frischwasser die Zisterne und insbesondere deren Boden spült, und dieses Spülwasser solange zur Regenwasser- Reinigungsweiche gepumpt wird, bis diese das Erreichen der gewünschten Wasserqualität anzeigt und ein Mindestwasser-Niveau in der Zisterne erreicht ist.- That the commissioning of the system can take place fully automatically by the Reaching a minimum water level in the fresh water supplied to the cistern and in particular rinses their bottom, and this rinsing water for rainwater Cleaning switch is pumped until it reaches the desired water quality displays and a minimum water level in the cistern has been reached.
Bild 1 stellt beispielhaft die obig beschriebene Regenwasser-Nutzungsanlage dar. Figure 1 shows an example of the rainwater utilization system described above.
