PATENTAMT.PATENT OFFICE.
Durch die Behandlung von Abwässern, welche durch organische Körper verunreinigt sind, mit metallischen Körpern, namentlich Zinkstaub, bei Anwesenheit von Kalk werden die enthaltenen Eiweißstoffe sowie einige Spaltungsprodukte derselben derart verändert, daß sie durch sogenannte organische Kohle zurückgehalten werden. Diese Abscheidung ist dann vollständig, wenn die von den Niederschlagen getrennten Flüssigkeiten durch ein Filter, welches mit der erwähnten Kohle beschickt ist, geht.By treating waste water polluted by organic bodies are, with metallic bodies, namely zinc dust, in the presence of lime changes the protein substances it contains and some of its breakdown products in such a way that that they are held back by so-called organic charcoal. This deposition is complete when the liquids separated from the precipitates by a Filter, which is loaded with the mentioned coal, goes.
Dieses Verfahren ist durch das D. R. P. 117151 bekannt geworden.This method has become known from D.R.P. 117151.
Demgegenüber besteht das Wesen der vorliegenden Erfindung darin, die durch Metalle, namentlich Zinkstaub, bei Gegenwart von Kalk veränderten organischen Körper, hauptsächlich Eiweiß und seine Spaltungsprodukte, der Flüssigkeit nicht durch sogenannte organische Kohle, sondern durch Körper zu ent-. ziehen, welche durch chemische und Flächenwirkung diesen Zweck erreichen, wie z. B. Tonerde, Eisenhydroxyd, deren Phosphate und andere Salze.In contrast, the essence of the present invention consists in the by metals, namely zinc dust, mainly organic matter changed in the presence of lime Protein and its breakdown products, the liquid not by so-called organic Coal, but through bodies to develop. draw which by chemical and surface effect achieve this purpose, such as B. clay, iron hydroxide, their phosphates and other salts.
In dem hierdurch erzeugten Niederschlage befinden sich die verunreinigenden, stickstoffhaltigen Substanzen. Derselbe kann mit dem durch die Vorreinigung enthaltenen Niederschlage vermischt, mittels Filterpresse ge- sammelt und der trockenen Destillation unterworfen werden. Die Rückstände derselben können wieder, mit Kalk und Zinkstaub vermengt, zur Vorreinigung benutzt werden, wobei naturgemäß die verwendete Tonerde, Eisenhydroxyd bezw. deren Phosphate und andere Salze unwirksam werden.The polluting, nitrogenous ones are found in the precipitate created in this way Substances. The same can be mixed with the precipitate contained in the pre-cleaning, removed by means of a filter press. collects and subjected to dry distillation. The residues of the same can be used again, mixed with lime and zinc dust, for pre-cleaning, where naturally the alumina used, iron hydroxide respectively. their phosphates and other salts become ineffective.
Da sich durch dieses Verfahren die eiweißartigen Körper aus Zuckersäften oder Zuckerfabriksabwässern gleichfalls abscheiden lassen, ohne daß der Zucker derselben niedergeschlagen oder verändert wird oder dessen Gegenwart der Anwendung des Verfahrens hinderlich wäre, so läßt sich dasselbe gleichfalls behufs Wiedergewinnung und Reinigung solcher Flüssigkeiten verwenden.Because this process removes the protein-like bodies from sugar juices or sugar factory wastewater also let it separate without the sugar of the same being precipitated or changed or its The presence of the application of the method would be a hindrance, the same can be said of the same use for the recovery and purification of such fluids.
Behufs praktischer Durchführung des Verfahrens mengt man zu den schon mit Kalk und Zinkstaub, mit oder ohne Kohle, vorbehandelten und geklärten Abwässern oder Flüssigkeiten eine gewisse, durch Vorversuch näher zu bestimmende Menge von Aluminium sulfat, Eisenoxydsulfat- oder Phosphatlösung in den Grenzen von 0,1 bis 5 kg pro 1 m3 Flüssigkeit. Der in der Flüssigkeit enthaltene Kalk bewirkt die Ausscheidung eines voluminösen basischen Niederschlages, welcher die durch die Wirkung des Zinkstaubes ver-For the purpose of practical implementation of the process, a certain amount of aluminum sulfate, iron oxide sulfate or phosphate solution within the limits of 0.1, which has to be determined by preliminary tests, is added to the wastewater or liquids that have already been pretreated and clarified with lime and zinc dust, with or without coal up to 5 kg per 1 m 3 of liquid. The lime contained in the liquid causes the elimination of a voluminous alkaline precipitate, which reduces the effects of the zinc dust.
