Verfahren zur Klärung von Abwässern. Patentiert im Deutschen Reiche vom 28. Juni 1908 ab. Process for the clarification of waste water. Patented in the German Empire on June 28, 1908.
Es ist bereits bekannt, behufs Reinigung kommunaler wie industrieller Abwässer diesen fein gemahlene Braunkohle oder Torf und danach ein Metallsalz zuzusetzen. Ferner hat man zwecks Gewinnung von künstlichem Dünger aus Flüssigkeiten, die Stickstoff und Phosphorsäure enthalten, jenen ein Gemisch von Kalk und Pflanzenfasern oder Torf zugesetzt. Es hat sich nun ergeben, daß der VerbrauchIt is already known to use these for the purification of municipal and industrial wastewater Add finely ground brown coal or peat and then add a metal salt. Furthermore has man for the purpose of obtaining artificial fertilizer from liquids, the nitrogen and phosphoric acid contain, to which a mixture of lime and vegetable fibers or peat is added. It has now been found that the consumption
ίο an Braunkohle oder Torf erheblich verringert und die Klärwirkung dadurch gesteigert werden kann, daß man die in der Braunkohle und im Torf enthaltenen Humusverbindungenίο significantly reduced in lignite or peat and the clarifying effect can be increased by the fact that one in the brown coal and humus compounds contained in peat
. mit Alkalien zunächst aufschließt und diese. first unlocks with alkalis and this
iS sodann dem zu reinigenden Abwasser zusetzt.iS then added to the wastewater to be cleaned.
Gemäß dem vorliegenden Verfahren werdenAccording to the present procedure will be
fein zerteilte Braunkohle oder Torf zunächst mit Wasser zu einem Brei angerührt und diesem sodann zweckmäßig unter Erhitzung Alkalien, z. B. Natronlauge, zugesetzt, wobei ein Überschuß von Natronlauge durch Zusatz von Kohle- oder Torf pulver neutralisiert werden kann. Die so* gewonnenen Humusverbindungen werden sodann dem zu reinigenden Abwasser in festem Zustande oder in Lösung zugesetzt; das Wasser erhält dadurch eine dunkelbraune bis schwarze Färbung und enthält die verschiedenen Humusverbindungen, speziell Humussäuren des Torfes oder der Braunkohle, weil gelöst in feinster Verteilung; die Wirkung derselben für den Reinigungsprozeß ist daher die denkbar größte. Setzt man nunmehr zu den so behandelten Wässern in bekannter Weise Salze, deren Basen mit oben genannten Säuren des Torfes usw. unlösliche Verbindungen eingehen, oder Mineralsäuren hinzu, so bildet sich ein sehr voluminöser Niederschlag unter völliger Klärung der Flüssigkeit.finely divided lignite or peat first mixed with water to a pulp and this then expediently with heating alkalis, z. B. sodium hydroxide, added, wherein an excess of caustic soda is neutralized by adding coal or peat powder can be. The humus compounds obtained in this way then become that to be cleaned Waste water added in solid state or in solution; this gives the water a dark brown to black color and contains the various humus compounds, especially humic acids from peat or peat Lignite, because it is dissolved in extremely fine distribution; the effect of the same for the cleaning process is therefore the greatest conceivable. Puts one now to the so treated waters in a known manner salts, their bases with The above-mentioned acids of peat etc. form insoluble compounds, or mineral acids added, a very voluminous precipitate forms with complete clarification of the Liquid.
