Abstract

The invention relates to an installation and to a method for converting ammonia and/or ammonium from waste water to elemental nitrogen and simultaneously sanitizing the water at a pH of < 9, preferably < 14, using lime and/or bentonite oxygen ozone and/or NOX.

Description

F.O.T- Verfahren AbwasserF.O.T- waste water process
Vorrichtung und Verfahren zur Umwandlung von Ammoniak und/oder Ammonium aus Abwasser in elementaren Stickstoff mit gleichzeitiger Hygienisierung.Device and method for converting ammonia and / or ammonium from waste water into elemental nitrogen with simultaneous sanitation.
Die vorliegende Erfindung betrifft ein Verfahren zur Oxydierung vonThe present invention relates to a process for the oxidation of
Ammonium bzw. Ammoniak aus Abwasser mit gleichzeitigerAmmonium or ammonia from wastewater with simultaneous
Hygienisierung.Sanitizing.
Ammonium bzw. Ammoniak werden üblicherweise durch biologischeAmmonium or ammonia are usually produced by biological
Verfahren aus dem Abwasser entfernt.Process removed from wastewater.
Es ist bekannt, daß Ammonium mit Ozon in Nitrat überführt werden kann, aber nur in geringen Konzentrationen aus Trinkwasser.It is known that ammonium can be converted to nitrate with ozone, but only in low concentrations from drinking water.
Mit dem F.O.T- Verfahren ist es gelungen Ammonium und/oder Ammoniak bis auf einen geringen Restgehalt zu entfernen. Bei einem pH-Wert von < 9 vorzugsweise 14 wird Ozon Sauerstoff und/oder NOX mit einer speziellen Vorrichtung im Wasser gelöst, so daß im drucklosen Zustand 40 bis 100 mg/l Ozon Sauerstoff und/oder NOX sich gelöst im Wasser befindet, (EN 25814 DEV G22) dadurch wird das Ammonium bzw. der Ammoniak nach einer Reaktionzeit in elementaren Stickstoff umgewandelt und gleichzeitig hygienisiert.With the F.O.T process, it was possible to remove ammonium and / or ammonia to a low residual content. At a pH of <9, preferably 14, ozone oxygen and / or NOX is dissolved in the water with a special device, so that 40 to 100 mg / l ozone oxygen and / or NOX is dissolved in the water in the depressurized state 25814 DEV G22) this converts the ammonium or ammonia into elemental nitrogen after a reaction time and at the same time sanitizes it.
Voraussetzung für die Behandlung des Abwassers nach dem F.O.T- Verfahren ist eine ausreichende Vorreinigung, wie beispielsweise Kläranlagenablauf ohne Nitratbehandlung. Die abfiltrierbaren Stoffe sollten >20 mg/l betragen, um den Verbrauch an Ozon bzw. NOX in wirtschaftlichen Grenzen zu halten.A prerequisite for the treatment of wastewater using the F.O.T process is adequate pre-treatment, such as sewage treatment plant outflow without nitrate treatment. The filterable substances should be> 20 mg / l in order to keep the consumption of ozone or NOX within economic limits.
Das Sauerstoff-Ozongemisch sollte < 20 Vo.-% Ozon bei 80 % technischen Sauerstoff betragen.The oxygen-ozone mixture should be <20% by volume ozone with 80% technical oxygen.
Der NOX Anteil sollte bei < 80 % liegen.The NOX percentage should be <80%.
Zur Vermeidung der Geruchsbelästigung wird die gesamte Abluft über einen Biofilter geführt. To avoid odor nuisance, the entire exhaust air is passed through a biofilter.
