Title
(EN) PROCESS AND APPARATUS FOR CLEANING OF WASTE WATER
(FR) PROCEDE ET APPAREIL D'EPURATION D'EAUX USEES
Abstract
(EN)
A process for cleaning of waste water and a corresponding apparatus for the embodiment hereof is described. By the process a column step is combined with a heat exchanging step, where the vapours from the waste water are led to the column, where the compounds in the waste water, which comprise more and less mobile compounds in relation to the mobility of the water, including inter alia weak acids and weak bases, will react and can be removed. By cleaning of manure an essential reaction between acetic acid and ammonia will occur. Additional compounds, including the more mobile compounds, inter alia ammonia, are conducted as steam via a compression step further on to the heat exchanger, where they condense and flow countercurrently to its own condensate. From the heat exchanger the more mobile content compounds can hereafter as steam be removed for possible further heat exchanging. The well cleaned waste water can at the bottom be drained off as condensate. By heat exchanging of manure an essential part of the more mobile compounds will consist of ammonia, which drained off at the top of the heat exchanger.

L'invention concerne un procédé d'épuration d'eaux usées et un appareil associé. Une phase colonne est combinée avec une phase échangeur thermique. Les vapeurs se dégageant des eaux usées sont amenées à la colonne. Les composés contenus dans les eaux usées, qui comprennent des composés plus et moins mobiles en fonction de la mobilité de l'eau, y compris, notamment, des acides et des bases faibles, réagiront et pourront être évacués. Le nettoyage du lisier provoquera une réaction entre l'acide acétique et l'ammoniaque. D'autre composés, y compris les composés mobiles, notamment l'ammoniaque, sont amenés sous la forme de vapeur par le biais d'une phase de compression vers l'échangeur thermique, dans lequel ils se condensent et s'écoulent à contre-courant vers son propre condensat. A partir de l'échangeur thermique, les composés du contenu mobile peuvent être évacués comme vapeur pour un nouvel échange thermique éventuel. Les eaux usées bien épurées peuvent être évacuées par le fond comme condensat. Par l'échange thermique du lisier, une part essentielle des composés plus mobiles sera constituée d'ammoniaque, évacué par le haut de l'échangeur thermique.
