Description
Verfahren zur Nutzbarmachung von Abfällen und Abwässern der Viskosefabrikation. Das Hauptpatent 368969 betrifft ein Verfahren zur Nutzbarmachung von Abfällen und Abwässern der Viskoseseidefabrikation, nach welchem diese gegebenenfalls unter Zusatz von Salzen, welche keine unlöslichen Xanthate bilden, durch Ausfällung der koagulationsfähigen Stoffe vermittels Erhitzens gereinigt und die Abfälle und Filtrate besonders verwendet werden.Process for the utilization of waste and wastewater from viscose production. The main patent 368969 relates to a process for the utilization of waste and wastewater from viscose silk manufacture, according to which these are cleaned by heating the coagulable substances, if necessary with the addition of salts that do not form insoluble xanthates, and the wastes and filtrates are specially used.
Damit die noch schwefelhaltigen koagulierten Rückstände bei der Zersetzung durch die Kohlensäure :der Luft keine Veranlassung zur Geruchsbelästigung geben können, werden den Abfällen, wie das Zusatzpatent 370592 beschreibt, heim Erhitzen Metalloxyde, Superoxyde oder katalytische Sauerstoffüberträger zugesetzt.So that the coagulated residues still containing sulfur during the decomposition due to the carbonic acid: do not give the air any cause for unpleasant odors the wastes, as described in the additional patent 370592, are heated Metal oxides, super oxides or catalytic oxygen carriers added.
Es hat sich nun herausgestellt, daß der gleiche Zweck, nämlich die Vermeidung der Geruchsbelästigung erreicht werden kann, wenn man, zunächst die Koagulation nach dem Hauptpatent vor sich gehen läßt und die koagulierten Rückstände, welche noch mehr oder minder schwefelhaltig sind, mit sehr geringen Mengender in denn Zusatzpatent angegebenen Zusätze oder anderen Stoffen überstreut. Man verwendet zu diesem Zweck beispielsweise folgende Stoffe: Eisenoxyd, Nickeloxyd, Mangansuperoxyd, Eisenfeile, Blutkohle, Zuckerkohle u. dgl.It has now been found that the same purpose, namely the Avoidance of odor nuisance can be achieved if one, first, the coagulation according to the main patent and the coagulated residues, which are still more or less sulphurous, with very small amounts in the additional patent specified additives or other substances. One uses for this purpose for example the following substances: iron oxide, nickel oxide, manganese superoxide, iron file, Blood charcoal, sugar charcoal, etc.
Es ist überraschend, daß bereits eine außerordentlich geringe Menge die Geruchsentwicklung an der Oberfläche der in Haufen gesetzten koagulierten Abfälle zu unter:drükken vermag, und daß diese entstehende Schicht imstande ist, etwa aus Odem. Innern des Haufens stammende Gerüche ebenfalls zu zersetzen.It is surprising that even an extremely small amount the odor development on the surface of the coagulated waste piled up to suppress: is able to suppress, and that this emerging layer is capable of something Edema. To decompose odors from inside the heap as well.
Der besondere Vorteil dieses Verfahrens liegt in einer sehr erheblichen Ersparnis an Chemikalien unter Erzielung des gleichen technischen Effektes.The particular advantage of this process lies in a very considerable one Saving of chemicals while achieving the same technical effect.
