Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Zer störung zellulärer Strukturen von Suspensionen von Mi kroorganismen insbesondere von Schlämmen aus biologi schen Kläranlagen durch Ultraschall.The invention relates to a method for Zer disruption of cellular structures of suspensions of Mi Croorganisms, in particular from biological sludges treatment plants using ultrasound.
Es ist bekannt, daß sich zelluläre Strukturen von Mi kroorganismen mit Hilfe von Ultraschall zerstören las sen.It is known that cellular structures of Mi destroy microorganisms with the help of ultrasound read sen.
In biologischen Kläranlagen entstehen durch Absetzvor gänge Primärschlämme und durch Verstoffwechselung bio logisch abbaubarer Stoffe durch Bakterien im Bele bungs- oder Tropfkörperverfahren Überschußschlämme (Bakteriensuspension), die häufig einer Faulung zur Erzeugung von Biogas (in der Hauptsache Methan) unter zogen werden. Dabei verbleibt Faulschlamm.In biological wastewater treatment plants, sedimentation occurs primary sludge and through metabolism bio Logically degradable substances by bacteria in the bele Exercise or trickling filter method Excess sludge (Bacterial suspension), which is often used for digestion Generation of biogas (mainly methane) under be drawn. This leaves digested sludge.
Da die Verwendung der anfallenden Schlämme als Dünger zunehmend erschwert wird, verbleibt nur noch entweder die Deponierung oder die Verbrennung.Because the use of the resulting sludge as fertilizer becomes increasingly difficult, only remains either landfill or incineration.
Da beides mit hohen Kosten verbunden ist, ist es von Nutzen die Schlammengen, sowohl nach Volumen wie nach Trockensub stanzmenge zu reduzieren. Die anfallenden Schlämme lassen sich relativ schlecht entwässern. Die Entwässe rung ist nur unter Zugabe von (teuren) Konditionie rungsmitteln möglich. Die Schlämme enthalten noch viel an organischer Substanz vor allem im Inneren der Zellen der Mikroorganismen. Diese organischen Zellin haltsstoffe sind biologisch schwer angreifbar.Since both with is associated with high costs, it is of benefit Mud volumes, both by volume and by dry sub to reduce the punching quantity. The resulting sludge are relatively difficult to drain. The drainage tion is only with the addition of (expensive) conditioning resources possible. The sludge still contains a lot of organic matter especially inside the Cells of microorganisms. This organic cellin Ingredients are difficult to attack biologically.
Durch die Behandlung der Schlämme mit Ultraschall wer den sowohl Primär-, Überschuß- als auch Faulschlamm in der Zellstruktur so zerstört, daß weitgehend nur noch die leeren Zellhüllen als absetzbare Stoffe übrig bleiben, während der größte Teil in echte oder kol loidale Lösungen übergeht. Im Gegensatz zu den nicht mit Ultraschall behandelten Schlämmen lassen sich die Restschlämme leichter und besser entwässern. Zur Ent wässerung ist ein geringerer Einsatz von Konditionie rungsmitteln notwendig.By treating the sludges with ultrasound who the both primary, excess and digested sludge in the cell structure so destroyed that largely only the empty cell shells remain as removable substances stay while most in real or col loidal solutions passes. Unlike that, not sludges treated with ultrasound Drain sludge more easily and better. To ent Watering is less use of conditioning means necessary.
Die in echte oder kolloidale Lösung gegangenen Stoffe können erneut einem mikrobiologischen Abbau unterwor fen werden. Dies kann zum einen im aeroben biologi schen Teil einer Kläranlage geschehen (Belebtschlamm-, Tropfköperverfahren), vorzugsweise dort aber als Pro tonendonator für die Denitrifikation dienen. Dadurch wird das oft ungünstige Verhältnis zwischen leicht ab baubaren Verbindung und dem Nitratgehalt des nitrifi zierten Abwassers verbessert. Eine weitere Möglichkeit besteht darin, die echt oder kolloidal gelösten orga nischen Stoffe gemeinsam mit den anfallenden Schlämmen auszufaulen und so zur Erzeugung von Biogas heranzu ziehen, das zur Energieerzeugung genutzt werden kann.The substances that have gone into real or colloidal solution can again subject to microbiological degradation be opened. On the one hand, this can be in the aerobic biological part of a sewage treatment plant (activated sludge, Drip twill process), but preferably there as a pro clay donor for denitrification. Thereby the often unfavorable relationship between slightly decreases buildable compound and the nitrate content of the nitrifi decorated wastewater improved. One more way consists of the real or colloidally solved orga substances together with the resulting sludge digestion and thus used to produce biogas pull that can be used to generate energy.
