Abstract
(DE)
Gegenstand der Erfindung ist ein Verfahren zur Behandlung von mit organischen Substanzen belastetem Abwasser durch Wasserstoffperoxid in Gegenwart eines Katalysators, wobei der Katalysator eine organische Metallkomplex-Verbindung aus Kationen von Eisen, Zink, Kupfer, Kobalt, Vanadium oder Mangan und einem aus Stickstoff-haltigen aromatischen Heterozyklen bestehenden Komplexbildner mit einem tertiären Alkylamin-Grundgerüst darstellt. Das Verfahren umfasst ferner die Dosierung der erfindungsgemäßen Metallkomplex-Verbindung zur Zersetzung der organischen Bestandteile im Abwasser und die Zersetzung der organischen Abwasserfracht an mit der organischen Metallkomplex-Verbindung geträgertem Katalysatormaterial.
(EN)
The invention relates to a method for treating wastewater containing organic substances, using hydrogen peroxide in the presence of a catalyst. The catalyst is an organic metal complex compound of cations of iron, zinc, copper, cobalt, vanadium, or manganese, and a complexing agent consisting of aromatic heterocyclic compounds containing nitrogen and a tertiary alkylamine matrix. The method also relates to the dosage of the metal complex compound according to the invention for degrading organic components in wastewater, and the degradation of the organic load in wastewater on catalyst material carried by the organic metal complex compound.
(FR)
La présente invention concerne un procédé de traitement d'eaux usées chargées en substances organiques au moyen de peroxyde d'hydrogène en présence d'un catalyseur qui se présente sous la forme d'un composé-complexe de métaux organique qui se compose de cations de fer, de zinc, de cuivre, de cobalt, de vanadium ou de manganèse et d'un agent complexant qui est lui-même composé d'hétérocycles aromatiques contenant de l'azote et présente une structure de base alkylamine tertiaire. Le procédé consiste à doser le composé-complexe de métaux pour décomposer les composants organiques contenus dans les eaux usées, et à décomposer la charge organique des eaux usées au contact avec la matière catalytique supportée par le composé-complexe de métaux organique.
