Description

Verfahren zur Reinigung von Wässern, insbesondere von Abwässern In der Patentschrift 53d.204 ist ein Verfahren zur Reinigung von wäßrigen Flüssigkeiten, insbesondere von Abwässern, z. B. dem sogenannten Ammoniakrollwasser der Kokereien, unter Verwertung der darin gelösten organischen Stoffe beschrieben. welches dadurch gekennzeichnet ist, daß man den zu reinigenden Flüssigkeiten die darin gelösten Stoffe, wie z. B. Pllenole. durch Behandlung mit festen Adsorptionsmitteln entzieht, die Adsorptionsinittel sodann durch Behandlung mit geeigneten Lösungsmitteln oder Gemischen von solchen von den adsorbierten Stoffen wieder befreit und schließlich die Reste der in den Adsorptionsmitteln zurückgehaltenen Lösungsmittel aus diesen auf geeignete Weise, insbesondere durch Erhitzen, z. B. durch Spülen mit Dampf, entfernt.Process for the purification of water, especially waste water In the patent specification 53d.204 is a process for the purification of aqueous liquids, in particular of sewage, e.g. B. the so-called ammonia roll water of the coking plants, under the recycling of the dissolved organic substances. which thereby is characterized in that the liquids to be cleaned are dissolved therein Substances such as B. Pllenole. removed by treatment with solid adsorbents, the adsorbent then by treatment with suitable solvents or Mixtures of such freed from the adsorbed substances and finally the residues of the solvents retained in the adsorbents from these in a suitable manner, in particular by heating, e.g. B. by rinsing with steam, removed.

Beim Arbeiten nach diesem Verfahren erhält man bei Behandlung von Amtllonialcrohwasser Lösungen, welche Gemische der verschiedenen im Rohwasser enthaltenen Stoffe, wie Phenole. Pyridinbasen, Naphthalin, Teer u. dgl., enthalten, die alsdann zwecks weiterer Verwendung meistens in irgendeiner Weise ganz oder teilweise noch getrennt werden Re üSS:'II.When working according to this procedure, one obtains when treating Official raw water solutions, which are mixtures of the various contained in raw water Substances such as phenols. Pyridine bases, naphthalene, tar and the like., The then for the purpose of further use mostly in any way wholly or partially be separated Re üSS: 'II.

Es wurde gefunden, daß man diese Trennungauf einfache Weise mit dein eigentlichen Adsorptionsvorgang nach dein Hauptpatent verbinden kann, wenn inan die Adsorption stufenweise in mehreren hintereinandergeschalteten Adsorptionsbehältern oder auch in verschiedenen Abteilungen eines und desselben Behälters ausführt. Es hat sich nämlich gezeigt, daß zu Beginn der Adsorption die Adsorptionsmittel sämtliche in delle Abwasser moldispers oder kolloidal gelösten oder suspendierten Bestandteile aufnehmen. daß jedoch itli Verlauf der weiteren Adsorlltion, besonders wenn man höhere Schichten des Adsorptionstnittels anwendet, eine weitgeliende und scharfe Trennung der adsorbierten Bestandteile innerhalb der verschiedenen Schichten der Adsorptionsinasse stattfindet. Leitet inan Ammoniakrohwasser durch zwei oder mehrere hintereinandergeschaltete mit Aktivkohle gefüllte Adsorber, so reichern sich bei geeigneter Betriebsweise die teerigen, in dein Wasser enthaltenen Bestandteile in dein ersten Adsorber an, während die wertvollen Phencile in dem zweiten Adsorber zurückgehalten «-erden. Die getrennte Gewinnung der von der Kohle aufgenommenen Bestandteile erfolgt dann durch Extraktion der Füllungen der einzelnen Adsorber gemäß dein Hauptpatent 534 204. mittels eines geeigneten Lösungsmittels, z. B. Benzol.It has been found that this separation can be easily achieved with your actual adsorption process according to your main patent can connect if inan the adsorption step by step in several adsorption vessels connected in series or in different departments of one and the same container. It it has been shown that at the beginning of the adsorption all the adsorbents Moldisperse or colloidally dissolved or suspended components in the wastewater take up. that itli course of further adsorption, especially if one uses higher layers of the adsorbent, a wide and sharp one Separation of the adsorbed components within the various layers of the Adsorptionsinasse takes place. Directs raw ammonia water through two or more series-connected adsorbers filled with activated carbon accumulate at suitable operation the tarry, contained in your water in components your first adsorber, while the valuable Phencile in the second adsorber held back "-grounds. The separate extraction of that absorbed by the coal Components is then carried out by extracting the fillings of the individual adsorbers according to main patent 534 204. by means of a suitable solvent, e.g. B. benzene.

Die getrennte Gewinnung der einzelnen in den Abwässern enthaltenen organischen Bestandfeile hat .in vielen Fällen noch folgenden Vorteil:» Oft enthalten die im Wasser in irgendeiner Form- enthaltenen Bestandteile, insbesondere die teerigen Stoffe, die die Kohle bzw. die sonstigen Adsorptionsmittel schädigen, indem sie beispielsweise auf ihnen verharzen und dadurch deren Adsorptionskapazität verringern. In diesen Fällen erfüllt der zur Abscheidung * der teerigen bzw. sonstigen schädigend wirkenden Bestandteile dienende Adsorber die Funktion eines. Vorreinigers, der die die Kohle schädigenden Bestandteile von den Hauptadsorbern, in denen die.wertvollen Bestandteile abgeschieden und gewonnen- werden, zurückhält.The separate extraction of each contained in the wastewater organic constituent file has the following advantage in many cases: Often the water contains components in some form, especially the tarry substances that damage the coal or other adsorbents, by gumming up on them, for example, and thereby their adsorption capacity to decrease. In these cases, the for separation * fulfills the tarry or other Damaging components serving adsorber the function of a. Pre-cleaner, the carbon-damaging components of the main adsorbers, in which the valuable Components separated and recovered, retains.

Statt, wie beschrieben, mehrere hintereinandergeschaltete Adsorber zu verwenden, kann man die stufenweise Adsorption gemäß der Erfindung auch in verschiedenen Abteilungen oder in geeigneter Weise getrennten Schichten des Adsorptionsmittels in einem und demselben Adsorptionsgefäß durchführen. Auch können natürlich je nach der gewünschten Betriebweise die einzelnen Adsorber oder Adsorberschichten oder -abteilengen in beliebigen anderen Kombinationen, z. B. unter Verwendung von Parallelschaltungen, Gruppenschaltungen u. dgl., angeordnet werden.Instead of several adsorbers connected in series, as described to use, one can also use the stepwise adsorption according to the invention in different Compartments or suitably separate layers of the adsorbent in one and the same adsorption vessel. Also can of course depending on the desired mode of operation, the individual adsorbers or adsorber layers or compartments in any other combination, e.g. B. using parallel connections, Group circuits and the like., Are arranged.

Statt die Adsorption in allen Stufen mit einem und demselben Adsorptionsmittel durchzufüfiren, kann man gegebenenfalls auch mit Vorteil in verschiedenen Stufen verschiedene, z. B. zwei oder mehrere verschiedene Adsorptionsmittel zur Anwendung bringen.Instead of adsorption in all stages with one and the same adsorbent to be carried out, one can optionally also with advantage in different stages various, e.g. B. two or more different adsorbents are used bring.
