  Verfahren zur Reinigung und Geruchlosmachung von Abwässern aller Art. 



   Gegenstand der Erfindung ist ein Verfahren zur Reinigung und Klärung von Ab-   wässern, und zwar Dicht   nur von   städtischen   und   Kanalabwässern   sondern auch von 
 EMI1.1 
 fabriken, Webereien, Farbenfabriken und ähnlichen Betrieben. 



   Es ist bekannt, zur   Klärung   von Wasser einerseits Ton und andererseits auch   manche   chemischen Stoffe zu benutzen. Als günstig ist bestimmter Ton, nämlich hoch-   praktischer Ton,   dem feine Mineraltrümmer silikathaltiger Gesteine, insbesondere ver-   wutcrte,   z. l   ! Schluff, zugemischt   sind, vorgeschlagen worden. Keines dieser Mittel er-   möglichst   aber schmutzige und übelriechende Fabriksabwässer so weit zu reinigen, geruch und geschmacklos zu machen, dass sie in die öffentlichen   Flussläufe   abgeführt werden können Überraschenderweise wird nun ein solcher Erfolg erreicht, wenn man mehrere Be-   handlungen   der   Wässer nacheinander   zur Anwendung bringt.

   Langwierige Versuche des   Krnnders haben   gelehrt, dass eine kombinierte Klärung mit Salz, ferner Ton und schliesslich mit Ton und Kalk jedes noch so stark verunreinigte Abwasser unschädlich macht. Es entsteht ein   klares, geruchfreies   Wasser, das frei von äusserlich erkennbaren Stoffen und auch frei von solchen ist, die Fischen, anderem Getier oder Pflanzen schaden. Es wird   al-li   ein Ergebnis erzielt, wie es weder jedes der Einzelelemente, Ton allein, Salz allein, Ton und Kalk oder Ton und Salz zusammen schaffen. 



   Nach der Erfindung wird das zu reinigende Wasser in getrennten Operationen mit

   abpe/ogell.   



   Als Salze haben sich die Chloride und löslichen Sulfate der Erden und Erdalkalien bweahrt, in erster Liuie die des magnesiums, Bariums, Aluminiums und Zinks. Auch
Ammoniumsalze, wie Ammoniumsulfat und ammoniumchlorid, sind hochwirksam. Dagegen sindAlkalisalzewenigervorteilhaft. 



   Diesen Einzelsalzen gleichwertig ist kaliendlauge. Versuche im grossen lehrten, dass volumen-Prozent kaliendlauge zusammen mit der geschilderten besonderen Einwirkung

 aus, wahrend von den anderen Salzen eine etwas grössere Menge erforderlich ist. 



   Die Bchandlung kann sowohl in der Reihenfolge geschehen, dass zunächst Ton, dann   'n (nd Kalk   und schliesslich die Salze genommen werden, zweckmässiger ist aber, mit   ''n Salzzusatz zu beginnen   und dann zu dem Ton, schliesslich zu dem Ton-Kalkgemisch uberzugehen. 



   Beispielsweise verfährt man folgendermassen :
Das schmutzige Abwasser wird zunächst mit dem Erdalkalichlorid oder einem der

  Process for the purification and deodorization of all types of waste water.



   The subject of the invention is a process for the purification and clarification of sewage, specifically only urban and sewer sewage but also from
 EMI1.1
 factories, weaving mills, paint factories and similar establishments.



   It is known to use clay on the one hand and some chemical substances on the other hand to clarify water. A certain clay is favorable, namely highly practical clay, the fine mineral debris of silicate-containing rocks, in particular wasted, z. l! Silt mixed in has been suggested. None of these means, however, as far as possible to purify dirty and foul-smelling factory wastewater, make it odorless and tasteless, that it can be discharged into the public rivers brings.

   Lengthy experiments by the Krnnder have shown that a combined clarification with salt, furthermore clay and finally with clay and lime render any wastewater, however heavily contaminated, harmless. The result is clear, odor-free water that is free of externally recognizable substances and also free of those that harm fish, other animals or plants. Al-li a result is achieved which neither of the individual elements, clay alone, salt alone, clay and lime or clay and salt together, can achieve.



   According to the invention, the water to be purified is used in separate operations

   The chlorides and soluble sulfates of the earths and alkaline earths have been used as salts, primarily those of magnesium, barium, aluminum and zinc. Also
Ammonium salts such as ammonium sulfate and ammonium chloride are highly effective. On the other hand, alkaline salts are less advantageous.



   Potassium lye is equivalent to these individual salts. Experiments on a large scale taught that the percentage by volume of potassium hydroxide solution together with the special effects described

 while a slightly larger amount of the other salts is required.



   The treatment can take place in the order that first clay, then lime and finally the salts are taken, but it is more appropriate to start with the addition of salt and then to move on to the clay, and finally to the clay-lime mixture .



   For example, one proceeds as follows:
The dirty wastewater is first with the alkaline earth chloride or one of the
