Abstract

A method of back-washing an activated carbon (activated charcoal) filter in a sewage treatment plant utilises hot water for the back-washing. The water is heated by the waste heat obtd. from the incineration of rubbish or sludge or from engine exhaust gases. After heating, the water is passed through the filter bed to desorb it and is then cooled and returned to the effluent inlet channel. Since, in order to back-flush a filter, it is of advantage to utilise an appreciably higher temp. than during the adsorption onto the filter material, the use of heat which would otherwise be wasted enables the back-flushing to be carried out considerably more economically at an only slightly increased cost.

Description

Verfahren zur Aktivkohle- Filter- Rückspülung Process for activated carbon filter backwash

und Einrichtung zur Durchführung des Verfahrens Die Wasserreinigung mittels Filtrierung durch Aktivkohle beruht auf Adsorption von Laststoffen, also deren Anlagerung an die Innere Oberfläche aktiver Kohle. and device for carrying out the process The water purification by means of filtration through activated carbon is based on adsorption of pollutants, i.e. their deposition on the inner surface of active carbon.

Um eine optimale Standzeit der Kohle zu erlangen, wird üblicherweise deren Rückspülung durchgeführt. Bei der Rückspülung erfolgt die Desorption angelagerter Stoffe.In order to achieve an optimal service life of the coal, is usually their backwashing carried out. During backwashing, the desorption of accumulated substances takes place Fabrics.

Erfahrungsgemäß erfordert der Adsorptionsprozeß niedrige Temperatur.Experience has shown that the adsorption process requires a low temperature.

Die Ablösung (Desorption) angelagerter Stoffe dagegen verläuft am besten bei erhöhter Temperatur, da mit der Temperaturaufnahme den zu desorb erenden Teilen kinetische Energie übertragen wird.The detachment (desorption) of deposited substances, on the other hand, takes place on best at elevated temperature, since with the temperature absorption the to be desorbable Share kinetic energy is transferred.

Die vorliegende Erfindung dient dazu, die gegebenen Eigenheiten der Adsorption und Desorption 1 m Sinne einer weitestgehenden Relnlgungseffizienz der Filterkohle zu deren Reaktivierung nutzbar zu machen.The present invention serves to address the given characteristics of the Adsorption and desorption 1 in the sense of the greatest possible control efficiency the To make filter carbon usable for their reactivation.

Beschreibung: In Kläranlagen bestimmter Systematik entstehen heiße Motorenabgase oder Verbrennungsabgase. Dies insbesondere dort, wo Verbrennung von Reststoffen oder von erzeugten Gasen (K lärgas etc. ) erfolgt.Description: In sewage treatment plants with a certain system, hot Engine exhaust or combustion exhaust. This especially where there is combustion of Residues or generated gases (sewage gas, etc.) takes place.

Die in den Abgasen enthaltene Wärme wird üblicherweise an die Atmosphäre abgegeben.The heat contained in the exhaust gases is usually released into the atmosphere submitted.

Anstatt die Wärme so ungenutzt in die Atmosphäre abzuleiten, wird sie erfindungsgemäß dem Rückspülwasser übertragen, welches für die desorptive Aktivkohlereinigung eingesetzt wird.Instead of discharging the heat into the atmosphere unused, will they are transferred according to the invention to the backwash water, which is used for desorptive activated carbon cleaning is used.

Erfindungsgemäß erfolgt dies in einem Speicherbecken, welches eine ausreichende Menge an gereinigtem Wasser (oder Trinkwasser) für einen Rückspülprozeß bereithält. Dem Speicherwasser- wird über geeignete Einrichtungen (Rohrspiralen, etc.), durch welche das warme Motoren- oder Verbrennungsabgas geführt wird, deren Wärme übertragen. Das Spülwasser wird nach vollzogener Rückspülung erfindungsgemäß In einen zwelten'Speicher geleitet, wo es abkühlt, ehe es dem Abwasserzulauf der Gesamtanlage zugeleitet wird; Beschreibung einer Einrichtung zur Durchführung des Verfahrens : Fig. I zeigt eine Flußdiagrammdraufsicht.According to the invention, this is done in a storage basin, which has a Sufficient amount of purified water (or drinking water) for a backwash process ready. The storage water is supplied via suitable devices (spiral pipes, etc.), through which the warm engine or combustion exhaust gas is passed, their Transfer heat. After backwashing has been completed, the rinsing water is according to the invention Passed into a second storage tank, where it cools down before it enters the sewage system Entire system is fed; Description of a facility for Execution of the method: Fig. I shows a flow chart top view.

Durch Fig. 1/4 erfolgt der Zulauf des Abwassers zu einer physikalischen Abwasserkläranlage. Im Bereich des Zulaufs befinden sich Rdckhaltebecken Fig. 1/5 mit Sperrschieber Fig. 1/6. Diese Rückhaltebecken dienen als Stauzone für die Zeit der Kohleregeneration-Aktivkoh lefilter- Rückspülung.Through Fig. 1/4 the inflow of the wastewater takes place to a physical one Sewage treatment plant. In the area of the inlet there are back retention basins Fig. 1/5 with locking slide Fig. 1/6. These retention basins serve as a storage zone for the time the carbon regeneration activated carbon filter backwash.

Im Behälter Fig. 1/10 wird durch Abfallwärme über die Heizspiralen Fig. 1/11 das Rückspülwasser erwärmt. Durch Zuleitung Fig. 1/3 wird das Rückspülwasser zum Aktivkohlefilterbett geführt und dient dort als Spülwasser zur Desorption auf die Aktivkohle angelagerter Partikel. Das Rückspülwasser wird über die Leitung Fig. 1/9 zu einem Abkühlstaubecken Fig. 1/8 geführt und dort abgekühlt. Nach Abkühl ung erfolgt Einleiten des Rückspülwassers über Zuleitung Fig. 1/17 zum Abwasserzulau kanl fig. 1/4.In the container Fig. 1/10, waste heat from the heating coils Fig. 1/11 heats the backwash water. The backwash water is supplied through the supply line Fig. 1/3 to the activated charcoal filter bed, where it serves as rinsing water for desorption the activated carbon of deposited particles. The backwash water is supplied via the line Fig. 1/9 led to a cooling reservoir Fig. 1/8 and cooled there. After cooling down The backwash water is introduced via the supply line Fig. 1/17 to the waste water inlet kanl fig. 1/4.

Das Rückspülwasser wird aus gereinigtem Abwasser entnommen, d. h., aus dem Ablauf Fig. 1/15 über die Zuleitung Fig. 1/16 zum Brauchwasserbehälter Fig 1/10 geführt.The backwash water is taken from purified wastewater, i.
