Description

Schwebstoff-Kontaktanlage zur Reinigung von Wasser Zusatz zum Patent: 1 142797 Die vorliegende Erfindung bezieht sich auf eine Schwebstoff-Kontaktanlage zur Reinigung von Wasser und stellt eine Weiterbildung der in dem Hauptpatent unter Schutz gestellten Schwebstoff-Kontaktanlage dar.Suspended matter contact system for cleaning water Addition to the patent: 1 142797 The present invention relates to a suspended matter contact system for the purification of water and is a further development of the in the main patent Protection against suspended matter.

Die Schwebstoff-Kontaktanlage des Hauptpatents besitzt eine den gesamten Querschnitt der Kläranlage ausfüllende rückspülbare Filteranordnung. Die Reinigung dieser Filteranordnung erfolgt durch Rückspülung in der Weise, daß zur Erzielung eines Wasserrückstoßes eine Entleerungsleitung vorgesehen ist, durch die eine entsprechende Wassermenge stoßartig abgeführt wird unter gleichzeitiger Absperrung der Rohwasserzufuhr. Die Abführungsleitung muß hierbei so bemessen sein, daß das Mehrfache des sonstigen Rohwasserdurchsatzes momentan abgelassen werden kann. Hierdurch sind unter Umständen Schlammverluste in Kauf zu nehmen, die nicht immer erwünscht sind. The suspended matter contact system of the main patent has the entire Cross-section of the sewage treatment plant filling backflushable filter arrangement. The cleaning this filter arrangement is carried out by backwashing in such a way that to achieve a water recoil a drainage line is provided through which a corresponding Amount of water is discharged abruptly while shutting off the raw water supply. The discharge line must be dimensioned so that the multiple of the rest Raw water throughput can be drained momentarily. This may cause Accepting sludge losses, which are not always desirable.

Es wurde nun gefunden, daß sich diese Nachteile vermeiden lassen, wenn erfindungsgemäß unterhalb des Filters eine vorzugsweise ringförmige, unten offene Luftglocke mit durch Ventile absperrbaren Entlüftungsrohren und einer mit diesen in Verbindung stehenden Luftzuführung angeordnet ist. Die erfindungsgemäß angeordnete Luftglocke wird während des Filterbetriebes allmählich mit Luft gefüllt und zur Filterrückspülung plötzlich entlüftet. Das in die Glocke ebenso plötzlich eindringende Wasser durchsetzt die Filteranordnung mit großer Geschwindigkeit von oben nach unten; hierbei können Rückstoßgeschwindigkeiten auftreten, die beispielsweise das 15- bis 20fache der sonstigen Filtrationsgeschwindigkeiten ausmachen. Ein weiterer Vorteil dieser erfindungsgemäß angeordneten Luftglocke liegt in der Vermeidung von Wasserverlusten und in der Tatsache, daß der Schlammumlauf nicht gestört wird, da sich die mit der Rückspülung im Zusammenhang stehenden Vorgänge oberhalb der Schlammtrennebene abspielen. It has now been found that these disadvantages can be avoided if according to the invention below the filter a preferably ring-shaped, below open air bell with vent pipes that can be shut off by valves and one with this related air supply is arranged. According to the invention arranged air bell is gradually filled with air while the filter is in operation and suddenly vented for filter backwashing. That into the bell just as suddenly penetrating water penetrates the filter assembly at great speed up down; recoil speeds can occur here, for example 15 to 20 times the other filtration speeds. Another The advantage of this air bell arranged according to the invention lies in the avoidance of Water losses and the fact that the sludge circulation is not disturbed, there the processes associated with backwashing are located above the sludge separation level play.

Die Zeichnung zeigt eine beispielsweise Ausführungsform der erfindungsgemäß vorgesehenen Luftglocke im Schnitt. The drawing shows an example embodiment of the invention provided air bell in the section.

Man erkennt bei 1 den sogenannten »Kontaktflockulator« mit seinen Bauelementen und das Filter2 innerhalb des Klärraumes. One recognizes at 1 the so-called "contact flocculator" with its Components and the filter2 within the clarification room.

Eine Hälfte dieser Schniffzeichnung (B) zeigt die Funktion des Apparates während des üblichen Flokkungs- und Filtrationsbetriebes, während in der zweiten Hälfte (A) die Vorgänge angedeutet sind, wie sie bei der Rückspülung des Filterteiles ablaufen. One half of this cross-sectional drawing (B) shows the function of the device during the usual flocculation and filtration operation, while in the second Half (A) the processes are indicated, as they are during the backwashing of the filter part expire.

Während des Filterbetriebes kommt es zu einer Verschlammung des Filterteiles, wodurch ein Anstau des Wasserspiegels innerhalb des Mischzylinders eintritt. Während des Filterbetriebes wird die Ringglocke 5 über die Fülleitung 6 mit Luft gefüllt. Der Kontakt4 löst bei bestimmter Stauhöhe den Rückspülvorgang aus. Zunächst wird die Rohwasserarmatut 3 geschlossen, und hiernach werden die Entlüftungsventile 7 geöffnet. Die vorher aufgefüllte Luft entströmt stoßartig der Ringglocke 5 über die Leitungen und die Entlüftungsventile7, so daß das nachströmende Wasser mit entsprechend hoher Geschwindigkeit das Filterteil in der in der Zeichnung angedeuteten Richtung von oben nach unten durchsetzt. When the filter is in operation, the filter part becomes silted up, whereby a build-up of the water level occurs within the mixing cylinder. While During the filter operation, the bell jar 5 is filled with air via the filling line 6. Contact 4 triggers the backwashing process at a certain level. First will the raw water armature 3 is closed, and then the vent valves 7 opened. The previously filled air flows out abruptly from the ring bell 5 the lines and the vent valves7, so that the inflowing water with accordingly high speed the filter part in the direction indicated in the drawing interspersed from top to bottom.

Hierdurch kommt es zu einer besonders energischen Filterspülung. Die herausgerissenen Schlammteilchen fallen in das Schlammbad der Schwebstoff-Kontaktanlage zurück. This results in particularly vigorous filter rinsing. The torn out sludge particles fall into the sludge bath of the suspended matter contact system return.

Eine Zeitschaltvorrichtung sorgt nach vollständiger Auffüllung der Ringglocke 5 mit Wasser für den Abschluß der Entlüftungsventile 7 und die Öffnung der Rohwasserarmatur 3. Der Luftausstoß dauert nur wenige Sekunden, so daß die Anlage nach kurzer Zeit schon wieder in Betrieb ist. A timer ensures that the Ring bell 5 with water for the closure of the vent valves 7 and the opening the raw water fitting 3. The air expulsion takes only a few seconds, so that the system is back in operation after a short time.
