Abstract

The invention relates to the preparation of a bituminous mixture in which part of the mixture comprises sewage sludge or residues from the incineration of sewage sludge. In the preparation process, the sewage sludge produced in the sewage plant (treatment plant) is used in the preparation of a bituminous mixture without significant expenditure of energy. In addition, the opportunity is offered of safe landfilling of incineration residues and of saving raw materials.

Description

Beschreibung der ErfindungDescription of the invention

Titel: Bituminöses Mischgut, Produkt und Verfahren Anwendungs -gebiet: Die Erfindung betrifft die Herstellung von bituminösem Mischgut, wobei ein Teil des Mischgutes aus Klärschlamm oder Verbrennungsrückständen von Klärschlamm besteht.Title: Bituminous mix, product and process Area of application: The invention relates to the production of bituminous mix, with a part of the mixed material consists of sewage sludge or combustion residues from sewage sludge.

Stand der Technik: Zur Herstellung von bituminösem Mischgut werden u.a. auch industrielle Nebenprodukte und Konsumabfälle verwendet (Zeitschrift Strafe und Autobahn, Hft 3/198o, S. 113 -118). Die Nebenprodukte und Konsumabfälle werden dem Mischprozeß in aufbereitetem Zustand (Reifenschnitzel, Müllverbrennungsasche, Metallhüttenschlacke usw.) zugeführt.State of the art: For the production of bituminous mix also used industrial by-products and consumer waste (magazine Strafe and Autobahn, volume 3 / 198o, pp. 113-118). The by-products and consumer waste will be the mixing process in the processed state (shredded tires, incineration ash, Metallurgical slag, etc.) fed.

Kritik des Standes der Technik: Abgesehen von einem gewissen Rohstoffverbrauch zur Herstellung von bituminösem Mischgut ist bei der Verarbeitung von z.B.Criticism of the state of the art: Apart from a certain consumption of raw materials for the production of bituminous mix is necessary when processing e.g.

Müllverbrennungsasche zur Verbrennung des Mülls ein nicht unerheblicher Energieaufwand erforderlich, um den Aschenrückstand dem Mischprozeß zuführen zu können.Incineration ash for incineration of the garbage is a not inconsiderable one Energy expenditure required to feed the ash residue to the mixing process can.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, den in Kläranlagen anfallenden Klärschlamm ohne wesentlichen Energieaufwand bei der Herstellung von bituminösem Mischgut zu verwenden, Lösung: Diese Aufgabe wird erfindungsmäßig durch die kennzeichnenden Merkmale der Ansprüche 1 bzw. 2 gelöst.Task: The invention is based on the task in sewage treatment plants resulting sewage sludge without significant energy expenditure in the production of to use bituminous mix, Solution: This task becomes according to the invention solved by the characterizing features of claims 1 and 2, respectively.

Der Klärschlamm wird mit einem Wassergehalt von 40 - 60 % bei der Vordosierung der Trockentrommel zur Verbrennung zugeführt. The sewage sludge has a water content of 40 - 60% at the Predosing fed to the drying drum for incineration.

Erzielbare Vorteile: Durch die Erfindung wird den Betreibern von Kläranlagen die Möglichkeit geboten, den anfallenden Klärschlamm kostengünstig abzugeben und gleichzeitig die Verbrennungsrückstände sicher zu deponieren.Achievable advantages: The invention will benefit the operators of sewage treatment plants offered the opportunity to dispose of the resulting sewage sludge inexpensively and at the same time to safely deposit the combustion residues.

Bei der Herstellung des o.g. bituminösen Mischgutes können bei der Verwendung von Klärschlamm sowohl Energie wie auch bisher eingesetzte Rohstoffe eingespart werden.When producing the above-mentioned bituminous mix, the Use of sewage sludge, both energy and raw materials previously used can be saved.
