Die Lösung dieser Aufgabe ist Gegenstand der im ersten und siebenten Anspruch offenbarten Erfindung. Weitere zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The solution to this problem is the subject of invention disclosed in the first and seventh claims. Further expedient configurations of the Invention are the subject of the dependent claims.
Das Verfahren zur Behandlung von Abwässern und Biogenen Reststoffen mit Biogas- und Energiegewinnung besteht darin, daß in einem Belebtschlammbecken unter Luftzufuhr Abwasser anfangs wie bekannt behandelt wird. Diese aerobe Behandlung von Abwasser wird jedoch vorzeitig, spätestens auf dem Höhepunkt der Abbauphase, durch Überleiten eines Großteils des im Nachklärbecken abgesetzten aktiven, nicht stabilisierte Schlamm in einen Biogaserzeuger abgebrochen. Dort wird der Schlamm Biogenen Reststoffen, deren Menge die Schlammenge deutlich übersteigt, beigemischt und die Mischung erwärmt im anaeroben Verfahren unter Biogasbildung zu festen Endstoffen und neutralen Flüssigdünger abgebaut, die in einem nachfolgenden Separator voneinander getrennt werden. Biogene Reststoffe fallen als Lebensmittelreste, Fettabscheiderinhalte, Gras- und Baumschnitt Bzw. -häcksel, Festmist, verdorbenes Silo, Schlachthofabfälle u.a.m. an. Vorzugsweise kann frische Gülle dem in den Biogaserzeuger eingebrachten Schlamm als biogener Reststoff beigemischt werden. Die festen Endstoffe werden in einer Kompostanlage unter Wärmegewinnung kompostiert bzw. wie Festmist auf landwirtschaftlichen Flächen ausgebracht. Das gewonnene Biogas wird zum Antrieb von Gasmotoren zur Gewinnung von Elektroenergie verwendet. Die dabei entstehende Abwärme wird wie die Wärme der Kompostanlage hauptsächlich zur Erwärmung des Belebtschlammbeckens und des Biogaserzeugers verwendet. Umgekehrt wird das einströmende frische Abwasser zur Kühlung der Gasmotoren mittelbar über einen Kühlmittelkreislauf verwendet. Der im Biogaserzeuger anfallende geruchsfreie Flüssigdünger kann in das Belebtschlammbecken zurückgeführt und mit frischem Abwasser vermischt werden, wenn er nicht auf Agrarflächen ausgebracht wird, wobei zur Einhaltung der Überwachungswerte das erforderliche BSB5/N-Verhältnis zu prüfen ist. Durch diese Kombination der aeroben mit der aneroben Behandlung von Abwasser und der Mischung des Biogenen Reststoffen kann die Größe der Kläranlage, die Verweilzeit des Abwassers und der für die Abbauprozesse benötigte Sauerstoffbedeutend reduziert werden. Das bedeutet weniger Invest- und Betriebskosten durch die Reduzierung des Klärbeckenvolumens und Senkung des Stromverbrauches für die Belüfter. Durch die Energiegewinnung aus Gülle/Klärschlamm/Biogenen Reststoffen kann der gesamte Energie und Wärmebedarf der Anlage gedeckt und zusätzlich Überschußenergie abgegeben werden.The process for treating wastewater and biogenic residues with biogas and energy generation consists in treating wastewater initially in a activated sludge tank with air supply as is known. However, this aerobic treatment of waste water is stopped prematurely, at the latest at the peak of the breakdown phase, by transferring a large part of the active, non-stabilized sludge deposited in the secondary clarifier to a biogas generator. There, the sludge is mixed with biogenic residues, the amount of which clearly exceeds the amount of sludge, and the mixture is heated in an anaerobic process, with the formation of biogas, broken down into solid end products and neutral liquid fertilizers, which are separated from one another in a subsequent separator. Biogenic residues fall as food residues, fat separator contents, grass and tree cuts or -häcksel, Solid manure, spoiled silo, slaughterhouse waste, etc. Fresh liquid manure can preferably be added to the sludge introduced into the biogas generator as a biogenic residue. The solid end products are composted in a composting plant with heat recovery or spread on agricultural land like solid manure. The biogas obtained is used to drive gas engines to generate electrical energy. The resulting waste heat, like the heat from the composting plant, is mainly used to heat the activated sludge tank and the biogas generator. Conversely, the incoming fresh wastewater is used to cool the gas engines indirectly via a coolant circuit. The odorless liquid fertilizer accumulating in the biogas generator can be returned to the activated sludge tank and mixed with fresh wastewater if it is not applied to agricultural areas, whereby the required BOD 5 / N ratio must be checked to ensure compliance with the monitoring values. This combination of the aerobic and the anerobic treatment of waste water and the mixture of the biogenic residues can significantly reduce the size of the sewage treatment plant, the residence time of the waste water and the oxygen required for the degradation processes. This means lower investment and operating costs by reducing the clarifier volume and reducing the electricity consumption for the aerators. By generating energy from liquid manure / sewage sludge / biogenic residues, the entire energy and heat requirements of the system can be covered and excess energy can also be released.
