Beschreibung:Description:
Ist der Anschluß an eine öffentliche Kanalisation nicht möglich, ist der Grundstückseigentümer selbst für die Behandlung des Abwassers verantwortlich.If connection to a public sewer system is not possible, the property owner is responsible for treating the wastewater.
Die Abwasserbehandlung erfolgt hier in Kleinkläranlagen.Wastewater treatment takes place here in small sewage treatment plants.
Als Kleinkläranlage werden Anlagen mit einer Reinigungskapazität von maximal 50 EW, bzw. mit einem Abwasseranfall von max. 8 rti3/d bezeichnet, wobei die Auslegung der Anlagen in DIN 42 61 Teil 1 und 2 festgelegt sind.Small sewage treatment plants are plants with a cleaning capacity of maximum 50 PE, or with a wastewater volume of max. 8 rti 3 /d, whereby the design of the plants is specified in DIN 42 61 Parts 1 and 2.
Die konventionellen Kleinkläranlagen bestehen aus einer Mehrkammerausfaulgrube und einer biologischen (aeroben) Nachreinigung.Conventional small sewage treatment plants consist of a multi-chamber septic tank and a biological (aerobic) post-treatment system.
Zur Nachreinigung stehen eine Vielzahl von Verfahren, wie Filtergraben, Pflanzenbeete, Teiche, Belebungsanlagen sowie Tropf- und Tauchkörperanlagen zur Verfügung.A variety of methods are available for subsequent cleaning, such as filter trenches, plant beds, ponds, aeration systems as well as drip and immersion body systems.
Diese Anlagen sind daher mindestens in 4 Kammern unterteilt (Vorklärung Iu.II, aerobe Behandlung, Nachklärung).These plants are therefore divided into at least 4 chambers (pre-clarification Iu.II, aerobic treatment, post-clarification).
Die hier vorgestellte Kleinkläranlage mit einer Kapazität von bis zu 50 EW besteht nur aus einem Behälter, der nicht in einzelne Kammern unterteilt ist.The small sewage treatment plant presented here with a capacity of up to 50 PE consists of only one tank, which is not divided into individual chambers.
Das Abwasser fließt hier direkt in die Kläranlage, dabei erfolgt der Ablauf der einzelnen Reinigungsphasen zeitlich hintereinander.The wastewater flows directly into the sewage treatment plant, with the individual cleaning phases taking place one after the other.
Über Tag wird das Abwasser in dem Behälter gesammelt und belüftet und dabei gereinigt.During the day, the wastewater is collected in the tank and aerated and cleaned.
In den Nachtstunden, mit geringem Abwasseranfall, erfolgt die Sedimentation, anschließend wird das über Tag zugelaufene und gereinigte Abwasser abgepumpt, bzw. abgelassen.Sedimentation takes place at night when there is little wastewater, and then the wastewater that has flowed in and been cleaned during the day is pumped out or drained.
Die Steuerung des Reinigungszyklus erfolgt mit einer Zeitschaltuhr.The cleaning cycle is controlled by a timer.
Schwiminstoffe werden durch eine großzügig dimensionierte Tauchwand zurückgehalten.Floating substances are retained by a generously dimensioned baffle.
Die Kläranlage verfügt über keinen gesonderten Schlammspeicher, da das Belebungsbecken so groß bemessen ist, daß der Schlamm im System verbleiben kann.The sewage treatment plant does not have a separate sludge storage facility because the aeration tank is so large that the sludge can remain in the system.
Aufgrund des hohen Schlammalters ist nur mit einem geringen "■Überschuß s chi ammanfall zu rechnen.Due to the high age of the sludge, only a small amount of excess sludge is to be expected.
Die Belüftung der hier vorgestellten Kleinkläranlage erfolgt durch ein Gebläse oder sonstigem Verdichter, der den Sauerstoff über einen Membranbelüfter am Boden den Sauerstoff ins Becken einträgt.The small sewage treatment plant presented here is ventilated by a blower or other compressor, which introduces the oxygen into the tank via a membrane aerator on the floor.
Alternativ ist auch eine Belüftung mit Injektoren möglich.Alternatively, ventilation with injectors is also possible.
Die Vorschaltung einer Mehrkammerausfaulgrube ist bei einer konventionellen Kleinkläranlage erforderlich, um das Abwasser vorzuklären und von sonstigen Grobstoffen zu befreien.The installation of a multi-chamber septic tank is necessary in a conventional small sewage treatment plant in order to pre-treat the wastewater and remove other coarse materials.
Hierdurch wird die nachfolgende aerobe Reinigungsstufe entlastet und gröbere Bestandteile, die zu Störungen des Anlagenbetriebes führen würden, zurückzuhalten.This relieves the load on the subsequent aerobic cleaning stage and retains coarser components that would otherwise cause disruptions to the system operation.
Eine Vorklärung ist bei der hier vorgestelltenA preliminary clarification is required for the
Kleinkläranlage nicht erforderlich. Die Reinigungskapazität ist so bemessen, daß auch die sonst in der VorklärungSmall sewage treatment plant is not required. The cleaning capacity is sized so that the wastewater that would otherwise be collected in the primary treatment
zurückgehaltene organische Schmutzfracht mitbehandelt werden kann.retained organic contaminants can also be treated.
Grobstoffe können aufgrund der Anlagenkonfiguration zu keinen Störungen führen. Hierdurch können Baukosten eingespart werden.Due to the system configuration, coarse materials cannot cause any disruptions. This can save construction costs.
Zudem fällt kein Fäkalschlamm an, der in einer größeren Kläranlage weiterbehandelt werden müßte.In addition, no faecal sludge is produced that would have to be further treated in a larger sewage treatment plant.
Der Abbau des im wesentlichen aus organischem Material bestehenden FäkaiSchlammes erfolgt hier bereits in der Kläranlage unter aeroben Bedingungen.The decomposition of the fecal sludge, which consists essentially of organic material, takes place in the sewage treatment plant under aerobic conditions.
Die Entsorgungskosten für den Fäkalschlamm, die einen hohen Anteil der Betriebskosten ausmachen, entfallen hier.The disposal costs for the faecal sludge, which make up a large proportion of the operating costs, are eliminated here.
Aus dieser Anlage ist lediglich der aerob stabilisierte, geruchlose Überschußschlamm und die evtl. vorhandene Schwimmschicht zu entsorgen.Only the aerobically stabilized, odorless excess sludge and any floating layer that may be present need to be disposed of from this system.
Die hier vorgestellte Kleinkläranlage speichert das über Tag zugelaufene Abwasser vollständig. Während der Reinigung kann kein Abwasser ablaufen.The small sewage treatment plant presented here stores all the wastewater that flows in during the day. During the cleaning process, no wastewater can flow out.
Eine hydraulische Überlastung, die bei konventionellen Kleinkläranlagen häufig auftritt, ist hier ausgeschlossen.Hydraulic overload, which often occurs in conventional small sewage treatment plants, is excluded here.
