Description
BeschreibungDescription
Die Erfindung betrifft eine Vorrichtung mit . der, in diskontinuierlich betriebenen Kläranlagen, sogenannten Aufstauanlagen oder SBR-Anlagen, 'im -Anschluß an die Abwasserbehandlung und die Sedimentation das gereinigte Abwasser aus dem Becken abgelassen werden kann.The invention relates to a device with which, in discontinuously operated sewage treatment plants, so-called impoundment systems or SBR systems, the purified waste water can be drained from the basin following the waste water treatment and sedimentation.
Die Erfindung umfaßt zwei Varianten, da das gereinigte Abwasser in Abhängigkeit von den örtlichen Verhältnissen im freien Gefalle abgelassen wird oder aus dem Becken, gepumpt werden muß.The invention includes two variants, since the purified waste water is either drained freely or has to be pumped out of the basin, depending on the local conditions.
Sie erfüllt folgende Forderungen:It meets the following requirements:
1. Schneller Abzug des gereinigten Abwassers1. Rapid removal of the treated wastewater
2. Es wird kein sedimentierter Schlamm angesaugt und während der Abzugsphase aufgewirbelt.2. No sedimented sludge is sucked in and stirred up during the discharge phase.
3. Während der Durchmischung außerhalb der Klarwasserabzugsphase gelangt kein Belebtschlamm in die Klarwasserabzugsvorrichtung.3. During mixing outside the clear water discharge phase, no activated sludge enters the clear water discharge device.
4.AlIe Leitungen sind gegen einfrieren frostsicher im Erdreich verlegt. ■ - ■ ·4.All cables are laid in the ground to protect them from freezing. ■ - ■ ·
5. Während der Klarwasserabzugsphase wird kein Schwimmschlamm . angesogen.5. During the clear water discharge phase no floating sludge is sucked in.
Zum Abzug des gereinigten Abwassers aus einer Aufstauanlage wurden in der Vergangenheit eine· Reihe von' Vorrichtungen entwickelt. Das Klarwasser bei einer Ableitung über eine. Druckleitung durch fest installierte oder schwimmende Pumpen abgepumpt. Bei einer Ableitung im freien Gefälle wird dasIn the past, a number of devices were developed to remove the purified wastewater from a reservoir. When the water is discharged via a pressure pipe, it is pumped out by permanently installed or floating pumps. When the water is discharged using free gravity, the
Klarwasser über motorisch absenkbare Tauchrohre oder eine schwimmende Abzugseinrichtungen abgelassen.Clear water is drained via motor-operated lowering pipes or a floating drainage system.
Die derzeit eingesetzten Vorrichtungen haben aber den Nachteil, daß mit dem Beginn der Klarwasserabzugsphase die Ansaugöffnung, über die das Klarwasser angesogen wird, durch in diesem Bereich angeordnete Antriebe geöffnet oder eingetaucht werden muß. Das Verschließen oder Herausheben der Ansaugöffnung ist erforderlich, da während der Durchmischungsphase kein Belebt- oder Schwimmschlamm in die Anzugseinrichtung gelangen darf.However, the devices currently in use have the disadvantage that when the clear water discharge phase begins, the intake opening through which the clear water is sucked in must be opened or submerged by drives arranged in this area. Closing or lifting out the intake opening is necessary because no activated or floating sludge may enter the intake device during the mixing phase.
Bei der hier "vorgestellten Vorrichtung wird die Ansaugöffnung durch eine federbelastete Rückschlagklappe oder durch eine über Hebel' und Gewichtskraft betätigte Verschlußvorrichtung (1.1 oder 2.1) geschlossen gehalten. Mit dem Öffnen der Abflußleitung z.B. des Schiebers (2.2) oder der Inbetriebnahme der Klarwasserabzugspumpe (1.4) wird infolge der Sogwirkung die Verschlußeinrichtung am Einlauf geöffnet. Das Klarwasser kann abfließen. Wird der Klarwasserabzug gestoppt schließt sich die Verschlußeinrichtung (1.1 oder 2.1) selbständig.In the device presented here, the intake opening is kept closed by a spring-loaded check valve or by a locking device (1.1 or 2.1) operated by a lever and weight. When the drain line, e.g. the slide valve (2.2) is opened or the clear water discharge pump (1.4) is started, the locking device at the inlet is opened as a result of the suction effect. The clear water can flow out. If the clear water discharge is stopped, the locking device (1.1 or 2.1) closes automatically.
Die Ansaugvorrichtung der Klarwasserabzugseinrichtung ist schwimmend ausgeführt oder wird durch einen Stellantrieb in einer bestimmten Eintauchtiefe geführt. Somit wird ein möglichst großer Abstand zum Schlammspiegel eingehalten und der Gefahr entgegengewirkt, daß Schwimmschlamm angesogen wird.The suction device of the clear water discharge system is designed to be floating or is guided by an actuator at a specific immersion depth. This maintains the greatest possible distance from the sludge level and counteracts the risk of floating sludge being sucked in.
Häufig liegt der Wasserspiegel im Becken höher als das Niveau ■der Ablaufleitung. Ohne eine Verschlußeinrichtung würde der Behälter bis zu ,dem Niveau der Ablaufleitung leerlaufen. Die hier vorgestellten Abzugseinrichtung wird bei einer Ableitung über eine Freigefälleleitung (2.5) z.B. durch einen Schieber (2.2) verschlossen. Mit' der Öffnung des Schiebers, wirdThe water level in the tank is often higher than the level of the drain pipe. Without a closure device, the tank would drain to the level of the drain pipe. The discharge device presented here is closed, for example, by a slide valve (2.2) when draining via a gravity pipe (2.5). When the slide valve is opened,
automatisch die Verschlußöffnung (2.1) im Ansaugbereich aufgesogen, das gereinigte Abwasser kann ablaufen.automatically the closure opening (2.1) in the suction area is sucked up and the cleaned waste water can drain away.
Bei einer Ableitung über eine Pumpe (1.4) wird bei der vorgestellten Klarwasserabzugsvorrichtung im Verlauf der Druckleitung (1.7), vorzugsweise im Probenahmeschacht (1.2), eine federbelastete oder durch Gewichtskraft betätigte Verschlußvorrichtung (1.3) angeordnet.' Mit Inbetriebnahme der Pumpe (1.4) wird die Verschlußeinrichtung (1.1) im Ansaugbereich aufgesogen und der druckseitige Verschluß (1.3) aufgedrückt. Das Abwasser kann somit ablaufen. Wird die Pumpe (1.4) abgestellt, schließen beide Verschlußeinrichtungen (1.1 und 1.3) selbständig. Die druckseitige Verschlußeinrichtung .(1.3) ist so zu bemessen, daß der Anpressdruck den anstehenden Wasserüberdruck, im Behälter deutlich übersteigt und die Leitung somit sicher verschlossen wird.When draining via a pump (1.4), a spring-loaded or weight-operated closure device (1.3) is arranged in the course of the pressure line (1.7) in the clear water drainage device presented, preferably in the sampling shaft (1.2). When the pump (1.4) is started up, the closure device (1.1) in the intake area is sucked up and the pressure-side closure (1.3) is pressed open. The waste water can then drain away. If the pump (1.4) is turned off, both closure devices (1.1 and 1.3) close automatically. The pressure-side closure device (1.3) must be dimensioned so that the contact pressure significantly exceeds the existing water pressure in the container and the line is thus securely closed.
Die. druckseitigen Verschlußeinrichtung (1.3) ermöglicht es zudem, die Ablaufdruckleitung (1.7) in frostfreier Tiefe zu verlegen. Eine Leitungsführung über den Wasserspiegel mit Entlüftungseinrichtung ist nicht erforderlich. Die Sicherheit gegen einfrieren wird somit erheblich erhöht.The pressure-side closure device (1.3) also makes it possible to lay the discharge pressure line (1.7) at a frost-free depth. It is not necessary to run the line above the water level with a venting device. This significantly increases the protection against freezing.
Bei der Erst- oder Wiederinbetriebnahme der Klarwasserabzugseinrichtung ist' diese mit Luft gefüllt. Damit die entsprechenden selbständig ■ arbeitenden Verschlußeinrichtungen (1.1, 1.3 2.1) funktionieren, ist die Abzugseinrichtung zu entlüften. Hierzu sind hinter der Verschlußeinrichtung an der Ansaugvorrichtung (1.1, 2.1) sowie vor dem Schieber (2.3) bzw. vor der druckseitigen Verschlußeinrichtung ein Entlüftungshahn (1·. 5, .1.6, 2.3, 2.4) angeordnet. Durch Öffnen der Ventile fließt Wasser in · die Leitung. Bei Vollfüllung werden die Entlüftungshähne ' geschlossen und die Abzugseinrichtung ist betriebsbereit 1 Daneben besteht auch die Möglichkeit die Abzugseinrichtung von unten .mit Wasser aus einer unter DruckWhen the clear water discharge device is first put into operation or put back into operation, it is filled with air. In order for the corresponding independently operating closure devices (1.1, 1.3 2.1) to function, the discharge device must be vented. For this purpose, a vent valve (1·. 5, .1.6, 2.3, 2.4) is arranged behind the closure device on the intake device (1.1, 2.1) and in front of the slide (2.3) or in front of the pressure-side closure device. By opening the valves, water flows into the line. When it is full, the vent valves are closed and the discharge device is ready for operation. It is also possible to fill the discharge device from below with water from a pressurized tank.
