Abstract

To clean water soiled with ammonia and/or fresh water, the whole of the water is passed over zeolite. The ammonia enrichment in the zeolite circuit is stripped, leaving clean water which can be used.

Description

Es ist bekannt, insbesondere im Bereich von Kokereien und/oder auch Kraftwerken, daß das Abwasser, was aus dem Prozeß abgeführt werden muß, mit Ammoniak belastet ist.It is known, particularly in the area of coking plants and / or power plants, that the waste water, which must be removed from the process, with ammonia is burdened.

Der Gesetzgeber erwartet, daß diese Belastung bis auf 10 ppm abgebaut werden muß.Legislators expect this burden to be reduced to 10 ppm got to.

Hierzu gibt es mehrere Verfahren.There are several ways to do this.

Wesentlich ist, daß man nach einem wirtschaftlichen Verfahren sucht, um mit wenig Aufwand diese an sich schon stark belastete Industrie wie Kokereien und/oder auch Kraftwerke nicht noch zusätzlich kostenmäßig wesentlich zu belasten.It is essential that you look for an economical process to do with little Effort this industry, which is already heavily burdened, such as coking plants and / or Power plants do not have an additional significant cost impact.

Aus diesem Grunde wird vorgeschlagen, die schwachbelasteten Abwässer und/oder Trinkwasser über einen Zeolithaustauscher projektiv anzureichern.For this reason, it is proposed to use the weakly polluted wastewater and / or Projectively enrich drinking water using a zeolite exchanger.

Hierdurch wird ein enormer Aufwand des Gesamtstrippens vom Gesamtwasser­ volumen gespart. Man kann ein solches Verfahren bis auf 10% des ursprünglichen Wasservolumens reduzieren.As a result, the total stripping of the total water is enormous volume saved. Such a procedure can be reduced to 10% of the original Reduce water volume.

Das Ammoniak wird aus dem Regenerier-Verfahrensschritt ausgelöst, abgestrippt und das Frischwasser wird rückgeführt. Das Ammoniak wird gewonnen und einem Verwendungszweck zugeführt.The ammonia is released from the regeneration process step, stripped and the fresh water is returned. The ammonia is won and one Purpose fed.

Claims (1)

Verfahren zur Reinigung von ammoniakhaltigem Abwasser und/oder Frischwasser dadurch gekennzeichnet, daß die gesamte Wassermenge über Zeolith geführt und eine Anreicherung im Zeolithkreislauf durch einen Stripper das Ammoniak aus dem dann verwendungsfähigen Frischwasser entfernt.Process for the purification of ammonia-containing wastewater and / or fresh water, characterized in that the entire amount of water is passed over zeolite and an enrichment in the zeolite circuit by a stripper removes the ammonia from the fresh water which can then be used.
