Description

Verfahren zur Unschädlichmachung von Abwässern aus Urteergewinnungsanlagen 'Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Unschädlichmachung der Abwässer aus Urteergewinnungsanlagen gemäß Patent 401467.Process for rendering waste water from primary tar extraction plants harmless The invention relates to a further embodiment of the method for rendering harmless the wastewater from primary tar extraction plants according to patent 401467.

Das Verfahren gemäß Hauptpatent kennzeichnet sich dadurch, daß durch die Abwässer, bei denen für hinreichende Askalität Sorge getragen ist, noch mehrere Stunden lang Luft hindurchgeleitet und daß gegebenenfalls die erhaltene schwach gefärbte Flüssigkeit einer weiteren B.eharidlung mit Entfärbungsmitteln unterworfen wird. Als Entfärbungsmittel der hier in Betracht kommenden Art werden in dem Hauptpatent bezieichnet Stoffe, wie Tierkohle, Hydrosilikate, Eisenverbindungen, wie Eisensulfat usw., oder an Eisenverbindungen reiche Rückstände.The method according to the main patent is characterized in that the wastewater, for which sufficient rigor has been taken care of, several more Air passed through for hours and that, if necessary, the obtained weak The colored liquid is subjected to further treatment with decolorizing agents will. The main patent refers to substances such as animal charcoal, hydrosilicates, iron compounds such as iron sulfate etc., or residues rich in iron compounds.

Es hat sich nun herausgestellt,- daß ein besonders wirksames kieselsäure-eisenhaltiges Produkt für die hier in Betracht kommenden Zwecke die Aschen aus Generatoren oder anderen. Öfen bilden. Es hat sich des weiteren herausgestellt, daß man bei Verwendung geeigneter Entfärbungsmittel unter Umständen die gemäß Hauptpatent vorzunehmende Entlüftung des Ausgangsmaterials einschränken bzw. ganz unterlassen kann.It has now been found - that a particularly effective iron-containing silica Product for the purposes under consideration here, the ashes from generators or others. Form ovens. It has also been found that when using suitable decolorizing agent may be the one to be carried out in accordance with the main patent Restrict or omit venting of the starting material.
