Description

Verfahren zur Entfernung des 1Vlangans aus manganhaltigem Wasser. Gegenstand der Erfindung ist ein Verfahren zur Entfernung des Mangans aus manganhaltigem Wasser durch Behandlung desselben mit Oxyden der .Doppelsalze des Mangans in Gegenwart von .'Fraß oder einem anderen trachytischen Tuff, Eine vorteilhafte Ausführungsform ist dabei die, daß man die Mangandoppelsalze, welche sich im Traß bzw. trachytischen Tuff bilden, durch Behandlung mit Permanganaten in unlösliche manganhaltige Doppelsalze höherer und höchster Oxydationsstufe überführt.Process for removing 1Vlangan from water containing manganese. The invention relates to a method for removing the manganese from manganese-containing Water by treating it with oxides of the double salts of manganese in the presence von .'Fraß or another trachytic tuff, an advantageous embodiment is the fact that you get the manganese double salts, which are in the Trach or trachytic Form tuff by treating with permanganates into insoluble manganese-containing double salts higher and highest oxidation level transferred.

Es wurde bereits vorgeschlagen, Mangan aus dem Wasser mittels Mangansalz abzuscheiden, indem man außer den niederen Oxydstufen der Mangansalze noch Permanganate hinzusetzte, um höhere 0xydstufen zu erzielen. Weiter wurden Zeolithe benutzt, um mittels Permanganaten die Manganzeolithe in unlösliche höhere Oxyde des Mangans überzuführen.It has already been suggested to remove manganese from the water using manganese salt to be deposited by adding permanganates in addition to the lower oxide levels of the manganese salts added to achieve higher oxide levels. Zeolites were also used to by means of permanganates, the manganese zeolites into insoluble higher oxides of manganese convict.

Demgegenüber wird nach dem vorliegenden Verfahren Traß angewendet, also das unter diesem Namen gewonnene natürliche Gestein und insbesondere solches von der Herkunft aus dem Eifelgebiet, insbesondere des Laacher Sees, der sich durch weitgehende Austauschkraft für das Verfahren gemäß der Erfindung im Gegensatz zu Bimsstein eignet. Bei diesem Verfahren wird durch Oxydation der leicht Sauerstoff abgebenden höheren Manganoxyde die Ausfällung der in Wasser gelösten Manganoxydulverbindungen dadurch bewirkt, daß die nicht abfiltrierbare Form der Oxydulverbindungen der Mangansalze in abfiltrierbare Oxydverbindungen übergeführt wird- im Gegensatz zu einem bekannten Verfahren, wo Tuffe zur Enthärtung, Enteisenung und Entmanganung verwendet werden und nicht nur die Entfernung der Härtebilder Kalk und Mangnesia beim Filtrieren über die Tuffe im Basenaustausch erfolgen soll, sondern auch die des Eisens und Mangans. Gegenüber der Verwendung künstlicher Zeoiithe hat die Verwendung des natürlichen Trasses gemäß der Erfindung den Vorteil, daß die Gefahr des Zusammenbackens vermieden wird, wie sie dort bei der Benutzung der reinen, hoch reaktiven Aluminatsilikate eintritt.In contrast, according to the present method, Traß is used, So the natural rock extracted under this name and in particular such from the origin of the Eifel region, in particular the Laacher See, which runs through extensive exchange power for the method according to the invention in contrast to Pumice stone is suitable. In this process, the oxygen is easily oxidized releasing higher manganese oxides, the precipitation of the manganese oxide compounds dissolved in water this causes the non-filterable form of the oxide compounds of the manganese salts is converted into filterable oxide compounds - in contrast to a known one Process where tuffs are used for softening, iron removal and manganese removal and not only the removal of the hardness constituents lime and mangnesia during filtration should take place over the tuffs in the base exchange, but also that of the iron and Manganese. Compared to the use of artificial zeolites, the use of natural Trasses according to the invention have the advantage that the risk of caking is avoided as it is there when using the pure, highly reactive aluminate silicates entry.

Versuche haben folgendes gezeigt: Behandelt man einen trachytischen Tuff, insbesondere den erwähnten Traß, mit Mangansalzen, so bilden sich neuartige Verbindungen in der Form von Doppelsalzen. Werden nun diese -Mangansalze weiter mit Persalzen, z. B. mit Permanganat, behandelt, so entstehen Mangandoppelsalze höherer und höchster Oxydationsstufe. In Verbindung mit dem trachytischen Tuff bzw. dem Traß sind diese Doppelsalze befähigt, die in Lösung vorhandenen, einfachen, gelösten Salze des Mangans aufzunehmen, -wobei es sich nicht nur um die Oxydation der in Lösung befindlichen Manganoxydule durch Sauerstoffabgabe der gebildeten Mangandoppelsalze, sondern um die Bildung von stets neuen Mangandoppelsalzen handelt, welche durch die in Lösung befindlichen Mangansalze in Verbindung mit dem Traß vor sich geht.Experiments have shown the following: Are you treating a trachytic New types of tuff, especially the trass mentioned, with manganese salts are formed Compounds in the form of double salts. Now these manganese salts will continue with persalts, e.g. B. treated with permanganate, this creates manganese double salts higher and highest oxidation level. In connection with the trachytic tuff or these double salts are capable of removing the simple, to absorb dissolved salts of manganese, -which is not only about the oxidation the manganese oxide in solution by releasing oxygen from the manganese double salts formed, but rather the formation of new manganese double salts, which through the manganese salts in solution goes on in connection with the trass.

Beispielsweise wird ein Wasser mit 9 mg Manganoxydul über ein Filter von 6o cm Schichthöhe und 50 mm 1. W. bei einer Durchflußgeschwindigkeit von 8 bis io in pro Stunde absolut #vßn" 4.Mgngan befreit. Durch Zuführung- von- T-uj;@sauerstoff, Ozon oder Sauersföff ahgebetideh ;@Ägenzien ist die Lebensdauer dieses Filters unbegrenzt.For example, a water with 9 mg of manganese oxide is freed through a filter with a layer height of 60 cm and 50 mm 1. W at a flow rate of 8 to 10 in per hour absolute # vßn "4. Mgngan. By supplying-T-uj; With oxygen, ozone or oxygen, the service life of this filter is unlimited.
