Abstract
Die Erfindung betrifft die Verwendung eines industriellen Klärschlammes zur Herstellung eines Baustoffes dadurch, daß dem Klärschlamm organische und/oder anorganische Additive zugegeben werden. Die in vielen Industriezweigen 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 anwendbare Möglichkeit der Weiterverarbeitung der Klärschlämme geschaffen wird.The invention relates to the use of an industrial sewage sludge for producing a building material by adding organic and/or inorganic additives to the sewage sludge. The sewage sludge that accrues as waste products in many industries is thereby easily converted into valuable building materials, which eliminates the need for disposal and at the same time creates a particularly environmentally friendly, economical and widely applicable possibility for further processing the sewage sludge.
Description
Die Erfindung betrifft die Verwendung eines industriellen Klärschlammes.The invention relates to the 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 produced as a waste product, the disposal of which (landfill, incineration, etc.) is problematic, complex and expensive for environmental reasons.
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 that in individual cases sewage sludge can be processed in such a way that the products obtained can be reused in recycling processes. However, such a procedure is expensive and is 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 Wiederverwendung von Abwassergemischen aus verschiedenen Produktionszweigen der Farben- und Putzindustrie nicht geeignet. Es ist auch nicht möglich, artfremde Abfälle aus anderen Industriezweigen mit einzubeziehen.For example, it is known from US-PS 40 96 061 to coagulate aqueous emulsion paint waste using organic substances and, after separating the resulting solid phase, to add an anionic agent with a dispersing effect. The product obtained in this way can be used to form a new emulsion paint after re-emulsification. However, in addition to the high costs, particularly for re-emulsification, this process has the disadvantage that different re-emulsifying agents have to be used for different dispersion coagulates in order to ensure the storage stability of the product produced from them. Due to these circumstances, the process is not suitable for broad application for the reuse of waste water mixtures from various production branches of the paint and plaster industry. It is also not possible to include dissimilar waste from other branches of industry.
Ferner ist es bekannt, Lackabfälle im Gemisch mit Additiven zur Herstellung von ausgehärteten Werkstoffen wie Entdröhnungs- und Verkleidungsplatten für den Kraftfahrzeugbau wie auch Paneelen zu verwenden (DE-OS 31 50 718, GB 20 48 288).Furthermore, it is known to use paint waste in a mixture with additives to produce hardened materials such as sound deadening and cladding panels for motor vehicle construction as well as panels (DE-OS 31 50 718, GB 20 48 288).
Der Erfindung liegt die Aufgabe zugrunde, ein weiteres Verwendungsverfahren für die Weiterverarbeitung von industriellen Klärschlämmen, insbesondere der Farben- und Putzindustrie zu schaffen, welches die Entsorgung der Schlämme entbehrlich macht und insbesondere gegenüber den bekannten Recyclingverfahren sowohl eine bessere Wirtschaftlichkeit als auch einen breiteren Anwendungsbereich bietet.The invention is based on the object of creating a further use process for the further processing of industrial sewage sludge, in particular in the paint and plaster industry, which makes the disposal of the sludge unnecessary and, in particular, offers both better economic efficiency and a broader field of application compared to the known recycling processes.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, den Klärschlamm im Gemisch mit organischen und/oder anorganischen Additiven als Putz, Mörtel, Kleber oder Spachtelmasse für Bauzwecke zu verwenden.To solve this problem, according to the invention it is proposed to use the sewage sludge in a mixture with organic and/or inorganic additives as plaster, mortar, adhesive or filler for construction purposes.
Dieser Vorschlag beruht auf der Erkenntnis, daß in vielen Industriezweigen, wie z. B. bei der Lack-, Dispersions- und Kunstharzproduktion sowie bei der Weiterverarbeitung dieser Produkte, ferner bei Lackierverfahren, bei der Holzfaserproduktion, in der Tapetenindustrie usw. Klärschlämme anfallen, deren Zusammensetzung geeignet ist, daraus vor ihrem Einsatz noch reaktive Baustoffe wie Putz, Mörtel, Kleber, Spachtelmasse und ähnliche Produkte herzustellen. Hierfür werden dem Klärschlamm entsprechend dem angestrebten Qualitätsstandard die jeweils notwendigen Additive zugesetzt. Dies ist in der Regel mit einem einfachen Mischgerät zu bewerkstelligen.This proposal is based on the knowledge that in many industries, such as the production of paint, dispersions and synthetic resins and the further processing of these products, as well as in painting processes, wood fibre production, the wallpaper industry, etc., sewage sludge is produced whose composition is suitable for the manufacture of reactive building materials such as plaster, mortar, adhesive, filler and similar products before use. To this end, the necessary additives are added to the sewage sludge in accordance with the desired quality standard. This can usually be done with a simple mixing device.
Die in einschlägigen Industriezweigen 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 anwendbare Möglichkeit der Weiterverarbeitung der Klärschlämme geschaffen wird.The sewage sludge that accrues as waste products in relevant industries is thus easily converted into valuable building materials, thus eliminating the need for disposal and at the same time creating a particularly environmentally friendly, economical and widely applicable option for further processing the sewage sludge.
Zur Verbesserung der physikalisch/chemischen Eigenschaften des Baustoffs kann dem Klärschlamm vor seiner Verarbeitung vor Ort erfindungsgemäß Zement zugesetzt werden.In order to improve the physical/chemical properties of the building material, cement can be added to the sewage sludge before it is processed on site.
Es ist ferner im Rahmen der Erfindung möglich, dem Baustoff zur Verbesserung der Verarbeitungseigenschaften und Erhöhung der Qualität bzw. der Lagerstabilität als Additive Dispersionen, Leime, Emulgatoren, Netzmittel und Konservierungsmittel zuzugeben. Eine ähnliche Wirkung wie durch Zugabe von Konservierungsmittel ist auch durch Erhitzen, UV- Bestrahlung oder ähnliche Verfahren erreichbar.It is also possible within the scope of the invention to add dispersions, glues, emulsifiers, wetting agents and preservatives to the building material as additives in order to improve the processing properties and increase the quality or storage stability. A similar effect to that achieved by adding preservatives can also be achieved by heating, UV radiation or similar methods.
Es besteht auch die Möglichkeit, als Additive anorganische Füllstoffe, die selbst als Abfallprodukt in anderen Industriezweigen anfallen und sonst zur Entsorgung auf eine Deponie gebracht werden müßten, zu verwenden. Hierfür kommen u. a. Basalt, Sand, Gips u. ä. in Frage.It is also possible to use inorganic fillers as additives, which themselves are waste products in other industries and would otherwise have to be disposed of in a landfill. Examples of such materials include basalt, sand, gypsum, etc.
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 produce building materials from a combination of several of the above to produce sewage sludge.
Falls erforderlich, kann zur Erhöhung des Festkörpergehalts der Klärschlamm einer physikalischen Behandlung durch Erhitzen oder Zentrifugieren sowie durch UV-Bestrahlung unterzogen werden.If necessary, the sewage sludge can be subjected to physical treatment by heating or centrifugation as well as by UV irradiation to increase the solids content.
Weitere vorteilhafte Verwendungsmöglichkeiten sind in den Unteransprüchen angegeben.Further advantageous uses are specified in the subclaims.
