Abstract

Element, partic. for use in biological effluent treatment plants, is solid or hollow and of any desired shape, e.g. spherical, tube section, cubic or other regular or irregular multi-surface body. It can be formed from a (un)foamed plastic, the closed pores or outer cell skin of which are surface abraded and roughened either mechanically, e.g. by machining, rasping, or grinding, or by chemical or other additives and treatments.

Description

Füllkörper aus Kunststoff für Tropfkörper in biologischen Kläranlagen.Packing of plastic for trickling filters in biological sewage treatment plants.

Die Erfindung bezieht sich auf Füllkörper aus Kunststoff für Tropfkörper in biologischen Kläranlagen.The invention relates to fillers made of plastic for trickling filters in biological sewage treatment plants.

Als Füllmaterial für Tropfkörper wurde bisher Lava- Schlacke oder anderes Gesteinsmaterial sowie Ziegelbrocken verwendet.As a filling material for trickling filters, lava slag or other rock material and bricks were used.

Es ist auch bekannt, PVC- Materialien in Form von gleichmäßig oder ungleichmäßig gewellten oder geknickten Platten, Gittern oder Röhren zu benutzen.It is also known to use PVC materials in the form of uniform or to use unevenly corrugated or kinked plates, grids or tubes.

Das Füllmaterial hat die Aufgabe, einen Haftgrund für die Mikroorganismen abzugeben und soll so gelagert sein, daß ein mögichst gleichmäßiges Durchrieseln mit Abwasser bei gleichzeitig gleichmäßiger Durchlüftung möglich ist.The task of the filling material is to provide a primer for the microorganisms to adhere to and should be stored in such a way that it trickles through as evenly as possible with wastewater with simultaneous even aeration is possible.

Durch das hohe spezifische Gewicht der bisher verwendeten Gesteinsmaterialen sind statisch passive Bauwerke notwendig, die hohe Baukosten verursachen.Due to the high specific weight of the rock materials used so far statically passive structures are necessary, which cause high construction costs.

Die in: letzter Zeit zur Anwendung gelangten PVC- Platten oder Röhren haben den Nachteil der glatten Oberflächen nit geringen Haftungsjöglichkeiten für die Mikroorganismen. Ferner entstehen hohe Her stellungskosten.The PVC sheets or tubes that have been used recently have the disadvantage of smooth surfaces with little chance of adhesion the microorganisms. Furthermore, high production costs arise.

Nach der Erfindung ist die Aufgabe gestellt, Füllkörper in einer besonders günstigen Form aus Kinststoff zu schaffen, mit dem die genannten Nachteile vermieden worden.According to the invention, the task is set in a special packing to create favorable form from Kinststoff, with which the disadvantages mentioned are avoided been.

Gelöst wird die gestellte Aufgabe dadurch, daß die Füllkörper als Voll- oder Hohökörper in jeder beliebigen Form, zum Beispiel als Kulgen, Rohrabschnitte, Würfel oder sonstige beliebige regelmäßige oder unregelmäßige vielglächige Körper ausgebildet sind und aus geschäumten oder ungeschäumtem Kunststoff bestehen, deren geschlosgenen Poren bzw. Zellhaut an ihren Oberflächen durch mechanische Bearbeitung, zum Beispiel durch Fräsen, Raspeln oder Schleifen oder durch chemische oder sonstige Zusätze und Behandlungen aufgerissen und aufgerauht ist. Dadurch wird eine optimale Haftung für die Mikroorganismen ermöglicht.The problem posed is achieved in that the packing as Solid or hollow bodies in any shape, for example as Kulgen, pipe sections, Cubes or any other regular or irregular polyglot Bodies are designed and made of foamed or non-foamed plastic, their closed pores or cell membranes on their surfaces through mechanical processing, for example by milling, rasping or grinding or by chemical or other means Additives and treatments are torn and roughened. This makes an optimal Liability for the microorganisms allows.

Der zur Verwendung kommende geschäumte oder ungeschäulte Kunststoff wird durch die erfindungsgemäße Behandlung zwar an der Oberfläche durch Aufreißen der Zellen aufgerauht, die inneren Zellen bleiben Jedoch geschlossen und gewährleisten, daß kein Wasser eindringen kann.The foamed or unpulled plastic that is used is due to the treatment according to the invention on the surface by tearing open of the cells roughened, but the inner cells remain closed and ensure that that no water can penetrate.

Das Material soll in seinem Anwendungsbereich chemisch und biologisch beständig sein.The material should be chemically and biologically in its area of application be constant.

Für höhere Belastungsfälle werden in weiterer Ausgestaltung der Eriindung zur Erhöhung der Druckfestigkeiten Verstärkungen aus anderen Materialien beigegeben, zum Beispiel Trageskelette aus geeigneten anderen Kuststoffen oder Beimengungen geeigneter Faserstoffe oder sonstiger Materialien.For higher load cases, the invention is further developed Reinforcements made from other materials have been added to increase the compressive strength, For example supporting skeletons made of suitable other plastics or admixtures suitable fibers or other materials.

Die Füllkörper nach der Erfindung sind so ausgebildet, daß sie in ihrer Größe und Form eine geführte Strömung in der Schüttung ermöglichen, die eine optimale Durchrieselung gewährleisten und in ihrem Anwendungsbereich chemisch und biologisch beständig sind. Das Material besteht,außer an der Oberfläche, au geschlosnen Zellen und Poren, sodaß möglichst wenig Wasser aufgenonen wird.The packing according to the invention are designed so that they are in their size and shape allow a guided flow in the bed, which a Ensure optimal trickling through and in their area of application chemically and are biologically stable. Except on the surface, the material is also closed Cells and pores so that as little water as possible is absorbed.
