Abstract

The fecal wastewater treatment system comprises toilet bowl pipes, by which grey water is discharged from the system for flushing toilets, and pumps and other electrically operating units, which are operated with solar energy. The pipes guides to filters, through which the grey water is guided. The pipe guides from a grey water area of the system, in which the cleaned water is present, into a wastewater tank. The grey water area flows into the pipe between self-draining cockpit and side. An independent claim is included for a method for fecal wastewater treatment using biofiltration for toilets.

Description

Kleinere Sport- und Vergnügungsschiffe – nachfolgend: Yachten – sind nach dem Stand der Technik mit Toiletten ausgestattet, die mit einem Pumpsystem betätigt werden. Mit einem Pumpenhub wird Seewasser durch ein Seeventil zugeführt und als Spülwasser benutzt. Mit dem Pumpendruck werden dann Spülwasser und Fäkalien durch dasselbe Seeventil nach außen entfernt. Auf Hochseeyachten ist diese Ausführung üblich. Auf Binnenseen sind solche Toiletten zunehmend verboten, weil es unerwünscht ist, dass Fäkalien unmittelbar in den See geleitet werden.smaller Sports and pleasure boats - hereinafter: yachts - are according to the state of the art equipped with toilets equipped with a pumping system be operated. With a pump stroke, seawater gets through fed a sea valve and used as rinse water. The pump pressure then rinse water and fecal matter removed by the same sea valve to the outside. On ocean-going yachts is this version is common. On lakes are such Toilets increasingly banned because it is undesirable that faeces are channeled directly into the lake.

Insbesondere bei Yachten, die auf Binnenseen gefahren werden, werden deshalb Chemietoiletten eingesetzt. Fäkalien werden in einen Tank geleitet, der mit einer Chemikalie gefüllt ist, die Fäkalien zersetzt. Diese Fäkalientanks sind in der Regel tragbar. Zum Leeren und Neubefüllen werden sie aus dem Schiff genommen, zu einer Entsorgungsstelle gebracht, dort entleert, wieder befüllt und dann wieder in das Schiff eingesetzt.Especially Yachts that are driven on inland lakes, therefore, become Chemical toilets used. Faeces are in a tank passed, which is filled with a chemical that decomposes fecal matter. These sewage tanks are usually portable. To empty and refill, they are taken out of the ship, too brought to a disposal site, there emptied, refilled and then reinstated in the ship.

Nach dem Patent EP 1 873 120 sind Fäkalienabwasserbehandlungsanlagen durch Biofiltration bekannt. Bei Toiletten, die die Lehre nach diesem Patent benutzen, werden Fäkalien zusammen mit dem Spülwasser in einen Tank geleitet, in dem die Fäkalien im Wege eines biologischen Prozesses abgebaut werden. Das Ergebnis ist eine nicht oder nur noch schwach riechende wässrige Flüssigkeit (”Grauwasser”), die als Abwasser entsorgt werden kann. Dies in gleicher Weise wie Abwasser allgemein, also in die öffentliche Kanalisation und unmittelbar in die Umwelt.After the patent EP 1 873 120 Fecal sewage treatment plants are known by biofiltration. For lavatories using the teachings of this patent, faeces, together with the rinse water, are channeled into a tank where the fecal matter is degraded by a biological process. The result is a no or only faintly smelling aqueous liquid ("gray water"), which can be disposed of as wastewater. This is the same as wastewater in general, ie in public sewers and directly in the environment.

Aufgabe der Erfindung sind Toiletten für Yachten mit Fäkalienabwasserbehandlungsanlagen durch Biofiltration.task the invention are toilets for yachts with Fäkalienabwasserbehandlungsanlagen by Biofiltration.

Nach dem Stand der Technik eignen sich diese Anlagen für Yachten nicht. Für Hochseeyachten deshalb nicht, weil das Spülwasser, das aus dem Meer angepumpt wird, den biologischen Kulturen der Biofiltration schaden würde. Für Binnensee-Yachten deshalb nicht, weil auf Binnenseen die unmittelbare Einleitung von Abwässern in den See zunehmend unzulässig ist.To In the prior art, these systems are suitable for yachts Not. For offshore yachts not because the rinse water, which is pumped from the sea, the biological cultures of biofiltration would hurt. For inland yachts, therefore, not because on lakes the immediate discharge of wastewater into the lake is increasingly inadmissible.

Nach der Erfindung wird die Aufgabe so gelöst: Das Grauwasser, das bei der Biofiltration entsteht, wird zur Toilettenspülung benutzt. (Anspruch 1)To The object is achieved as follows: the gray water, which arises during the biofiltration becomes a toilet flush used. (Claim 1)

Damit wird diese Anlage sowohl für seegehende Yachten tauglich wie auch für Binnenseeyachten. Bei den erstgenannten kann das Grauwasser unbedenklich in die Biofiltration zurückgeleitet werden.In order to This facility is suitable for seagoing yachts as well as for inland yachts. In the former can the gray water safely returned to biofiltration become.

Bei Binnenseeyachten können die geringen Überschussmengen, die noch entsorgt werden müssen, in den Abwassertank eingeleitet werden. Die überschießende Menge von Grauwasser, die nicht als Spülwasser benutzt wird, kann bei Hochseeyachten problemlos noch entsorgt werden. Um dafür ein gesondertes Seeventil zu vermeiden, wird vorgeschlagen, dass dies in die Leitung geschieht, die vom selbstlenzenden Cockpit ohnehin schon nach außen führt. (Anspruch 2)at Inland yachts can control the small excess quantities, which still need to be disposed of, discharged into the waste tank become. The excess amount of greywater, which is not used as rinse water, can be used in ocean-going yachts be easily disposed of. For a separate To avoid seacock, it is suggested that this be in the line happens anyway, which leads from the self-bailing cockpit anyway to the outside. (Claim 2)

Für Binnenyachten ist diese Leitung für Seen unzweckmäßig, in die auch kleine Menge von Grauwasser nicht eingeleitet werden dürfen. Stattdessen wird eine andere Lösung vorgeschlagen, die zudem auch bei den Hochseeyachten möglich ist, die einen Abwassertank haben. Bei Binnenseeyachten ist ein Abwassertank die Regel. In diesen Abwassertank kann Grauwasser ohne Weiteres eingeleitet werden. (Anspruch 3)For Inland yachts this line is inappropriate for lakes, in which even small amount of gray water can not be discharged allowed to. Instead, another solution is suggested which is also possible with the ocean-going yachts, the have a waste water tank. Inland Sea Yachts is a wastewater tank the rule. Greywater can easily enter this wastewater tank be initiated. (Claim 3)

Je nach Grad der biologischen Reinigung kann Grauwasser noch einen Farbton haben, was zwar hygienisch unbedenklich ist und die technische Funktion und Brauchbarkeit der Anlage nicht beeinträchtigt. Zur optischen Verbesserung und auch mit Ziel, dass Grauwasser auf diese Weise Trinkwasserqualität erhält, wird vorgeschlagen, der Anlagen nach Anspruch 1 einen weiteren Filter nachzuschalten. (Anspruch 4)ever Greywater can still do one after the degree of biological purification Hue, which is hygienic and the technical function and usability of the facility is not affected. to visual enhancement and also with the goal that greywater affects this Drinking water quality, it is proposed the systems according to claim 1 downstream of a further filter. (Claim 4)

Bei der Anlage nach dem Patent werden eine ganze Reihe von Pumpen eingesetzt. Einmal für die Anlage selbst. Diese sind in Intervallen laufend eingeschaltet und bewirken einen ständigen Durchfluss, der biologisch erwünscht ist. Luftpumpen tragen Luft in die Anlage ein, die ebenfalls für den biologischen Prozess benötigt wird. In die Leitungen nach den Ansprüchen 2, 3 und 4 können ebenfalls Pumpen eingesetzt werden. Zweckmäßig werden die Pumpen mit elektrischem Strom betrieben. Dazu wird vorgeschlagen, dass dieser Strom mit einer Solaranlage erzeugt wird, wie sie für Yachten längst Standardtechnik ist. Dies wird auch im Hinblick darauf vorgeschlagen, dass der ständige Einsatz von Pumpen beim biologischen Prozess benötigt wird, also auch zu Zeiten, zu denen die Anlage nicht benutzt wird. Mit Solarstrom kann dies unbegrenzt lange Zeit besorgt werden, was die Anlage insoweit wartungsfrei macht. (Anspruch 5)at The system according to the patent, a whole series of pumps are used. Once for the plant itself. These are at intervals continuously switched on and cause a constant flow, the is biologically desirable. Air pumps carry air in the Plant, which is also for the biological process is needed. In the lines according to the claims 2, 3 and 4 can also be used pumps. expedient The pumps are powered by electricity. It is suggested that This electricity is generated by a solar system, as it is for Yachts have long been standard technology. This will also be in view It suggested that the constant use of pumps needed in the biological process, including at times, to which the plant is not used. With solar power this can be indefinitely long time worried, what the system so far maintenance-free power. (Claim 5)

Selbstverständlich sind Anlagen nach dem Patent nicht nur für Yachten zweckmäßig sondern für sämtliche Einsatzgebiete, insbesondere für Wohnmobile, Caravans, Züge, Flugzeuge, Busse, Ölplattformen, Hotels, Gartenhäuser und alleinstehende Häuser. In allen Fällen ist schon die Wasserersparnis der Anlagen nach der Erfindung ein Vorteil. Der weitere Vorteil besteht in den meisten Fällen darin, dass die Anlage nach der Erfindung ein weitgehend geschlossenes System ist, bei dem nur noch geringfügige Restmengen entsorgt oder einer anderen Verwendung zugeführt werden müssen.Of course, systems according to the patent are useful not only for yachts but for all applications, especially for campers, caravans, trains, planes, buses, oil rigs, hotels, garden sheds and detached houses. In all cases, the water savings of the systems according to the invention is an advantage. The further advantage consists in most cases in the fact that the system according to the invention is a largely closed system in which only insignificant gige remaining quantities must be disposed of or put to another use.
