Abstract
Description
Nr. 391125No. 391125
Die Erfindung betrifft eine Anordnung zur Reinigung von verunreinigtem Wasser, insbesondere zur Reinigung von anaerob oder aerob wenigstens teilweise vorgereinigtem kommunalem Abwasser, mit einer Bodenköiperfilterkammer, die mehrere, mit Luftzwischenräumen übereinander angeordnete Filterschichten aufweist, durch die das zu reinigende Wasser hindurchtropft und dabei gereinigt wird, wobei die Filterschichten in vorzugsweise tassenförmigen Trögen aufgenommen sind, deren Böden flüssigkeitsdurchlässig ausgebildet sind.The invention relates to an arrangement for cleaning contaminated water, in particular for cleaning anaerobically or aerobically at least partially pre-cleaned municipal waste water, with a bottom body filter chamber which has a plurality of filter layers arranged one above the other with air gaps, through which the water to be cleaned drips and is thereby cleaned, the filter layers being accommodated in preferably cup-shaped troughs, the bottoms of which are liquid-permeable.
Solche Anordnungen, die auch als Bodenkörperfilterkammem bezeichnet werden, werden insbesondere zur Reinigung verunreinigter Abwässer mit einem Schwebstoffgehalt von kleiner als 0,3 mg/1, wie sie nach anaerober oder aerober Vorreinigung kommunaler Abwässer anfallen, verwendetSuch arrangements, which are also referred to as bottom-body filter chambers, are used in particular for cleaning contaminated wastewater with a suspended matter content of less than 0.3 mg / l, such as occurs after anaerobic or aerobic pre-purification of municipal wastewater
Bodenkörperfiltefkammem sind Reinigungsanlagen für kommunale Abwässer, bei denen die Reinigung durch aerobe Umsetzungs-und Zersetzungsprozesse in einem mikrobiellen Bewuchs an der Beschickungsebene (Biokruste) erfolgt. Je nach der Intensität der Beschickung mit Abwasser dauert es unterschiedlich lange, bis sich diese Biokruste ausgebildet hat. Eine voll ausgebildete Biokruste hemmt allerdings den Wasserdurchtritt. Durch die fortschreitende Ausbreitung der Biokruste wird das anfallende Abwasser aus den Faulanlagen gleichmäßig über die Fläche der Anlage verteilt Dieser Teil der Beschickungsebene, der durch starken Bewuchs gekennzeichnet ist, verhindert ein weiteres Einsickem des zufließenden bzw. aufgestauten Abwassers.Soil-body filter chambers are cleaning systems for municipal wastewater, in which the cleaning is carried out by aerobic conversion and decomposition processes in a microbial growth at the loading level (bio-crust). Depending on the intensity of the loading with wastewater, it takes a different amount of time until this organic crust has developed. A fully developed organic crust, however, inhibits water penetration. Due to the progressive spread of the bio-crust, the waste water from the digestion plants is evenly distributed over the area of the plant. This part of the loading level, which is characterized by heavy growth, prevents further infiltration of the inflowing or pent-up waste water.
Die Ausbildung von Wasserlacken in einer Bodenkörperfilterkammer verringert ihre Reinigungskraft erheblich. Es ist daher notwendig, eine hinreichend große Fläche vorzusehen, um eine Verschlammung der Filterschichte zu verhindern bzw. zu verzögern.The formation of water-based paints in a floor filter chamber considerably reduces their cleaning power. It is therefore necessary to provide a sufficiently large area to prevent or delay silting up of the filter layer.
Auf Grund einschlägiger Vorschriften (z. B. ONORM B 2502) ist es aus diesem Grunde auch notwendig, Filterkammern mehrmals, z. B. viermal jährlich auf ihre Durchlässigkeit hin zu prüfen. Wird eine Verschlammung der Filterschichte festgestellt, so ist diese abzuheben und durch neues Material zu ersetzen. Gemäß der ONORM B 2502 sind Filterkammem mit 2 m^/EGW (EGW = Einwohnergleichwert) zu bemessen.Due to the relevant regulations (e.g. ONORM B 2502) it is therefore necessary to filter chambers several times, e.g. B. four times a year to check their permeability. If the filter layer becomes clogged, remove it and replace it with new material. According to ONORM B 2502, filter chambers with 2 m ^ / EGW (EGW = equivalent population) are to be dimensioned.
Da der mikrobielle Abbau des zu reinigenden Abwassers lediglich in der obersten Filterschichte (bis zu 5 cm Tiefe) vor sich geht, erfordern die bekannten Bodenkörperfilterkammem sehr große Flächen.Since the microbial degradation of the wastewater to be cleaned only takes place in the uppermost filter layer (up to 5 cm depth), the known soil filter chambers require very large areas.
Es ist daher auch schon vorgeschlagen worden, bei biologischen Reinigungsanlagen mehrere Filter übereinander anzuordnen. In diesem Zusammenhang wird auf die AT-PS 241 372 und 201 003 verwiesen, aus welch letzterer eine Bodenkörperfilterkammer der eingangs genannten Gattung bekannt istIt has therefore already been proposed to arrange several filters one above the other in biological cleaning systems. In this connection, reference is made to AT-PS 241 372 and 201 003, from which the latter a bottom body filter chamber of the type mentioned at the beginning is known
Wenn die Filterschichten in tassenförmigen Trögen aufgenommen und die Böden der tassenförmigen Tröge flüssigkeitsdurchlässig ausgebildet sind, wird nicht nur die wirksame Oberfläche vergrößert, sondern überstehendes Wasser wird in den jeweils darunter angeordneten tassenförmigen Trog geleitet. Damit ist gewährleistet, daß jede Filterebene nur mit soviel Abwasser beschickt wird, wie ohne Beeinträchtigung der Gesamtreinigungswirkung gereinigt werden kann.If the filter layers are accommodated in cup-shaped troughs and the bottoms of the cup-shaped troughs are designed to be liquid-permeable, not only is the effective surface increased, but excess water is led into the cup-shaped trough arranged below it. This ensures that each filter level is only loaded with as much wastewater as can be cleaned without affecting the overall cleaning effect.
Filter mit mehreren übereinander angeordneten Filterschichten sind auch aus der DE-OS 28 40 751 und der US-PS 4 238 335 bekannt. Das aus der DE-OS 28 40 751 bekannte Filter ist ein Entkalkungsfilter für eine Abwasserbehandlungsanlage, das in einem Tankkörper untergebracht ist. Mit dem bekannten Entkalkungsfilter soll insbesondere Abwasser, das reich an Kalziumsulfat ist, in der Weise behandelt werden, daß Gips ausgefällt wird.Filters with a plurality of filter layers arranged one above the other are also known from DE-OS 28 40 751 and US Pat. No. 4,238,335. The filter known from DE-OS 28 40 751 is a decalcifying filter for a wastewater treatment plant, which is housed in a tank body. With the known decalcifying filter in particular wastewater that is rich in calcium sulfate is to be treated in such a way that gypsum is precipitated.
Die Filterschichten des aus der US-PS 4 238 335 bekannten Filters enthalten Sand, um im Seewasser enthaltene Feststoffanteile auszufiltern. Aerobe Umsetzungen und Zersetzungsvorgänge finden in den Filtern gemäß der DE-OS 28 40 751 oder der US-PS 4 238 335 nicht statt.The filter layers of the filter known from US Pat. No. 4,238,335 contain sand in order to filter out solids contained in the sea water. Aerobic reactions and decomposition processes do not take place in the filters according to DE-OS 28 40 751 or US Pat. No. 4,238,335.
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Bodenkörperfilterkammern zu verbessern und insbesondere die Abführung des in der Bodenköiperfilterkammer gereinigten Wassers zu vereinfachen.The invention is based on the object of improving the known bottom body filter chambers and in particular of simplifying the removal of the water cleaned in the bottom body filter chamber.
Erfindungsgemäß wird diese Aufgabe bei einer Anordnung der eingangs genannten Gattung dadurch gelöst, daß das die Filterschichten der Bodenköiperfilterkammer aufnehmende Gehäuse unten offen ist und daß unmittelbar unter dem unten offenen Gehäuse ein vorzugsweise mit Kies od. dgl. gefüllter Sickerschacht angeordnet istAccording to the invention, this object is achieved in an arrangement of the type mentioned at the outset in that the housing receiving the filter layers of the bottom body filter chamber is open at the bottom and in that a drainage shaft, preferably filled with gravel or the like, is arranged directly below the housing which is open at the bottom
Auf diese Weise wird das gereinigte Abwasser ohne Beeinträchtigung der Leistungsfähigkeit der erfindungsgemäßen Anlage beseitigt. Insbesondere sind das gereinigte Abwasser abführende Leitungen entbehrlich.In this way, the cleaned wastewater is removed without impairing the performance of the plant according to the invention. In particular, the cleaned waste water discharge pipes are unnecessary.
Die Unteransprüche betreffen vorteilhafte Ausgestaltungen der erfindungsgemäßen Anordnung.The subclaims relate to advantageous refinements of the arrangement according to the invention.
