Description

Verfahren zur Reinigung von Abwässern aus der Verarbeitung bitumenhaltiger Mineralien, wie Schwelwasser, unter gleichzeitiger Gewinnung von Kunstharzen Die Abwässer aus den der Verarbeitung bitumenhaltiger Mineralien dienenden Verfahren, z. B. der Kokerei, Schwelerei, Holzdestillation, enthalten Phenole und phenolartige Stoffe, welche die Wasserläufe, denen die Abwässer zugeführt werden, verunreinigen.Process for the purification of wastewater from the processing of bituminous Minerals, such as smoldering water, with the simultaneous extraction of synthetic resins Wastewater from the processes used to process bituminous minerals, z. B. the coking plant, wallowing, wood distillation, contain phenols and phenol-like Substances that pollute the watercourses to which the wastewater is fed.

Der Gegenstand der Erfindung ist ein Verfahren zur Abscheidung von Phenolen und phenolartigen Stoffen aus den Abwässern der Verarbeitung von bitumenhaltigen Mineralien, welches darin besteht, daß die Abwässer mit Aldehyden, z. B. Formaldehyd oder Furfurol, behandelt werden, und zwar unter Erwärmen, wobei sich der größte Teil der Verunreinigungen in der Form von kunstharzähulichen Körpern abscheidet.The subject of the invention is a method for the deposition of Phenols and phenol-like substances from the wastewater from the processing of bituminous Minerals, which consists in that the wastewater with aldehydes, e.g. B. formaldehyde or furfural, with heating, the largest being Part of the impurities is deposited in the form of synthetic resin-like bodies.

Vor oder während der Behandlung mit Aldehyden können den Abwässern Klärmittel, z. B. Aluminiumsulfat oder Bleiessig, zugesetzt werden.Before or during the treatment with aldehydes can the wastewater Clarifying agents, e.g. B. aluminum sulfate or lead acetic acid can be added.

Das Verfahren kann in geschlossenen Gefäßen und gegebenenfalls unter erhöhtem Druck ausgeführt werden; zweckmäßig ist langdauerndes Erwärmen auf ungefähr 10o°. Das Verfahren läßt sich allerdings auch in der Kälte ausführen, erfolgt dann aber in unvollkommener Weise und unter Aufwendung längerer Zeit. Wenn die Phenole aus den Abwässern nahezu restlos entfernt werden sollen, so läßt man der Reinigung durch Aldehyde eine solche durch Flotation in an sich bekanntem Verfahren folgen, wobei außer anderen, der Flotation fähigen Stoffen insbesondere Kohlenschlamm verwendet wird.The process can be carried out in closed vessels and, if necessary, under increased pressure are performed; Long-term heating to approximately is advisable 10o °. The process can, however, also be carried out in the cold, if this is the case but in an imperfect way and with a long expenditure of time. When the phenols are to be removed almost completely from the sewage, it is left to the purification aldehydes are followed by flotation in a process known per se, in addition to other substances capable of flotation, coal sludge is used in particular will.

Das gereinigte Schwelwasser hat eine Härte von wenig über Null. Es eignet sich u. a. für Kesselspeisezwecke und ist den Wasserläufen, denen es zugeführt wird, nicht schädlich. Ausführungsbeispiel 1 ooo 1 Schwelwasser mit einem Gehalt von ,41,6 kg in Äther löslichen Stoffen - 4,16 °/", von welchen 34,8 kg - 3,48 "/" in Natronlauge löslich sind, werden in einem Eisenkessel mit 30 kg einer käuflichen 40prozentigen Formaldehydlösung versetzt und 16 Stunden auf etwa 10o° erwärmt. Nach 72stündigem Stehen werden die abgeschiedenen Harze abfiltriert und getrocknet; ihre Menge beträgt 38 kg.The purified smoldering water has a hardness of just over zero. It is suitable, among other things, for boiler feeding purposes and is not harmful to the watercourses to which it is fed. Embodiment 1, ooo 1 smoldering water with a content of .41.6 kg ether-soluble substances - 4.16%, of which 34.8 kg - 3.48 "/" are soluble in sodium hydroxide solution, are poured into an iron kettle with 30% kg of a commercially available 40 percent formaldehyde solution are added and the mixture is heated for 16 hours to about 100 ° C. After standing for 72 hours, the deposited resins are filtered off and dried, the amount of which is 38 kg.

Das Filtrat enthält dann noch 2,56o kg 0,256 "/" in Äther lösliche Bestandteile, welche sämtlich in Natronlauge löslich sind. Demnach sind durch obige Behandlung bereits 93,9 "1" der phenolartigen Stoffe entfernt. Das so vorgereinigte_ Abwasser wird mit Kohlenschlamm von der Schlammhalde flotiert. Es werden 59 kg Schlamm auf i ooo l verwendet. Nach der Flotation ist der Phenolgehalt nur noch I,22 kg pro Kubikmeter - 0,I22 °/o. Es werden also 97,4 °%o der Verunreinigung ausgeschieden.The filtrate then still contains 2.560 kg of 0.256 "/" which are soluble in ether Components that are all soluble in sodium hydroxide solution. Accordingly, through the above Treatment already removed 93.9 "1" of phenolic substances. That Wastewater pre-cleaned in this way is floated with coal sludge from the sludge dump. 59 kg of sludge per 100 liters are used. After the flotation is the phenol content only 1.22 kg per cubic meter - 0.122 per cent. So there will be 97.4% o of the contamination eliminated.
