Abstract
Description
Verwendung eines industriellen Klärschlamms. Use of an industrial sewage sludge.
In der Industrie fallen vielfach als Abfallprodukte Klärschlämme an, deren Entsorgung (Deponie, Verbrennung usw.) aus Gründen des Umweltschutzes problematisch bzw. aufwendig und teuer ist.In industry, sewage sludge is often a waste product, Their disposal (landfill, incineration, etc.) is problematic for reasons of environmental protection or is complex and expensive.
Es ist zwar bekannt, die Klärschlämme in Einzelfällen so zu verarbeiten, daß es möglich ist, die daraus gewonnenen Produkte im Recyclingverfahren wiederzuverwenden. Eine solche Verfahrensweise ist jedoch kostspielig und kommt nur selten in Betracht.It is known to process sewage sludge in individual cases in such a way that that it is possible to reuse the products obtained from it in the recycling process. However, such a procedure is costly and rarely considered.
So ist es beispielsweise aus der US-PS 40 96 061 bekannt, wässrige Dispersionsfarbenabfälle durch organische Stoffe zu koagulieren und nach Abtrennung der entstehenden Feststoffphase diese mit einem dispergierend wirkenden anionischen Agens zu versetzen. Das auf diese Weise gewonnene Produkt ist nach Reemulgierung zur Neubildung einer Dispersionsfarbe verwendbar. Bei diesem Verfahren ist es aber neben den hohen Kosten insbesondere für die Reemulgierung von Nachteil, daß man für unterschiedliche Dispersionskoagulate verschiedene Reemulgierungsmittel einsetzen muß, um die Lagerstabilität des hieraus herzustellenden Produktes zu gewährleisten. Aufgrund dieser Umstände ist das Verfahren für eine breite Anwendung zur Widerverwendung von Abwassergemischen aus verschiedenen Produktionszweigen der Farben- und Putz industrie nicht geeignet. Es ist auch nicht möglich, artfremde Abfälle aus anderen Industriezweigen mit einzubeziehen.For example, it is known from US Pat. No. 4,096,061, aqueous To coagulate emulsion paint waste by organic matter and after separation the resulting solid phase this with a dispersing anionic Agent to relocate. The product obtained in this way is after re-emulsification can be used to create a new emulsion paint. But with this procedure it is In addition to the high costs, in particular for re-emulsification, the disadvantage that one use different re-emulsifying agents for different dispersion coagulates must in order to ensure the storage stability of the product to be manufactured from it. Because of these circumstances, the method is for wide application for reuse of wastewater mixtures from different branches of production of paint and plaster not suitable for industry. It is also not possible to waste alien waste from others Industries to be included.
Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit der Weiterverarbeitung von industriellen Klärschlämmen, insbesondere der Farben- und Putzindustrie zu schaffen, welche die Entsorgung der Schlämme entbehrlich macht und gegenüber bekannten Recclinyverfahren sowohl eine bessere Wirtschaftlichkeit als auch einen breiteren Anwendungsbereich bietet.The invention is based on the object of a possibility of further processing from industrial sewage sludge, especially from the paint and plaster industry, which makes the disposal of the sludge superfluous and compared to known recycling processes both better economy and a wider range of applications offers.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, den Klärschlamm zur Herstellung eines Baustoffes durch Zugabe organischer und/oder anorganischer Additive zu verwenden.To solve this problem it is proposed according to the invention, the sewage sludge for the production of a building material by adding organic and / or inorganic additives to be used.
Dieser Vorschlag beruht auf der Erkenntnis, daß in vielen Industriezweigen, wie z.B. bei der Lack-Dispersions- und Kunstharz produktion sowie bei der Weiterverarbeitung dieser Produkte, ferner bei Lackierverfahren, bei der Holzfaserproduktion, in der Tapetenindustrie usw. Klärschlämme anfallen, deren Zusammensetzung geeignet ist, daraus Baustoffe wie Putze, Mörtel, Kleber, Spachtelmasse u.ä. Produkte herzustellen, indem dem Klärschlamm entsprechend dem angestrebten Qualitätsstandard die jeweils notwendigen Additive zugesetzt werden. Dies ist in der Regel mit einem einfachen Mischgerät zu bewerkstelligen.This proposal is based on the knowledge that in many branches of industry, such as in paint dispersion and synthetic resin production as well as in further processing of these products, also in painting processes, in wood fiber production, in the Wallpaper industry etc. sewage sludge is produced, the composition of which is suitable from it building materials such as plaster, mortar, glue, filler, etc. Manufacture products, by adding the sewage sludge according to the desired quality standard necessary additives can be added. This is usually done with a simple one To accomplish mixing device.
Die als Abfallprodukte anfallenden Klärschlämme werden dadurch in einfacher Weise in wertvolle Baustoffe umgewandelt, womit deren Entsorgung entfällt und gleichzeitig eine besonders umweltfreundliche, wirtschaftliche und vielfach anwendbar Möglichkeit der Weiterverarbeitung der Klärschlämme geschaffen wird.The sewage sludge arising as waste products is thereby in easily converted into valuable building materials, which means that there is no need to dispose of them and at the same time a particularly environmentally friendly, economical and often applicable possibility of further processing of the sewage sludge is created.
Zur Verbesserung der physikalisch/chemischen Eigenschaften des Baustoffes können dem Klärschlamm vor seiner Verarbeitung vor Ort erfindungsgemäß Zement oder ähnliche Produkte zugesetzt werden.To improve the physical / chemical properties of the building material can cement or the sewage sludge prior to its processing on site according to the invention similar products are added.
Es ist ferner im Rahmen der Erfindung möglich, dem Baustoff zur Verbesserung der Verarbeitungseigenschaften und Erhöhung der Qualität bzw. der Lagerstabilitat zusätzlich Dispersionen, Leime, Emulgatoren, Netzmittel, Konservierungsmittel u.ä.It is also possible within the scope of the invention to improve the building material the processing properties and increase in quality or storage stability additional dispersions, glues, emulsifiers, wetting agents, preservatives, etc.
zuzugeben. Eine ähnliche Wirkung wie durch Zugabe von Konservierungsmittel ist auch durch Erhitzen, UV-Bestrahlung oder ähnliche Verfahren erzielbar.admit. An effect similar to that of adding preservatives can also be achieved by heating, UV irradiation or similar processes.
Es besteht auch die Möglichkeit, als Additive anorganische Füllstoffe, die selbst als Abfallprodukte in anderen Industriezwei gen anfallen und sonst zur Entsorgung auf eine Deponie gebracht werden müßten, zu verwenden. Hierfür kommen u.a.There is also the possibility of using inorganic fillers as additives, which themselves arise as waste products in other branches of industry and otherwise for Waste disposal would have to be taken to a landfill to use. Come for this i.a.
Basalt, Sand, Gips u.ä. in Frage.Basalt, sand, plaster, etc. in question.
Es ist auch im Rahmen der Erfindung möglich, Baustoffe aus einer Kombination mehrerer der o.g. Klärschlämme herzustellen.It is also possible within the scope of the invention to use a combination of building materials to produce several of the above-mentioned sewage sludges.
Falls erforderlich, kann der Festkörpergehalt der Klärschlämme durch physikalische Verfahren, wie z.B. Erhitzen oder Zentrifugieren, erhöht werden.If necessary, the solids content of the sewage sludge can through physical processes such as heating or centrifugation can be increased.
Besonders vorteilhafte Verwendungsmöglichkeiten sind in den Unteransprüchen 4 bis 8 angegeben.Particularly advantageous possible uses are set out in the subclaims 4 to 8 indicated.
