Abstract

Wastes are mixed, sterilized and formed into a feedstock for digestion. Following this, the residues are pressed, de-watered and sent to combustion in a furnace. The furnace additionally burns the biogas from digestion. Biogas is also fed to a packaged generation plant, to produce heat and electricity. Thickened sludge is stripped of ammonia before further processing as described. It is recycled with recovered water. The liquid phase is also purified by reverse osmosis.

Description

Das kürzlich erlassene gesetzliche Verbot der Tiermehlverfütterung führt zu veränderten Nutzungs- und Entsorgungsverfahren von vorhandenem und entstehendem Tiermehl insbe­ sondere unter Hygieneanforderungen.The recent ban on animal meal feeding has changed Use and disposal procedures for existing and emerging animal meal, in particular especially under hygiene requirements.

Das nachfolgend beschriebene Verfahren betrifft eine Verfahrenskette aus den beiden zentra­ len Prozeßstufen Biogasproduktions-(Vergärung) und Verbrennungsanlage.The process described below relates to a process chain from the two centra len process stages of biogas production (fermentation) and incineration plants.

Dazu wird in oder aus einer TBA (Tierkörper-Behandlungsanlage) hygienisierter (z. B. 133°C, 3 bar) Tierbrei in eine Biogasproduktionsanlage in unterschiedlichen Mengen eingebracht und mit unterschiedlichen Beimengungen Klärschlamm zusammen vergoren. Das entstehende Rohbiogas kann danach über die bekannten Technologien in Energie (elektr. und therm.) aber auch über eine anschließende Reinigung in Treibstoff umgewandelt werden. Der verbleibende Gärrest wird separiert und das daraus abgepreßte Trockengut einer Verbren­ nungsanlage zugeführt und verbrannt.For this purpose, hygienized (e.g. 133 ° C, 3 bar) animal pulp in a biogas production plant in different quantities introduced and fermented together with different admixtures sewage sludge. The resulting raw biogas can then be converted into energy (electr. and therm.) but can also be converted into fuel via subsequent cleaning. The remaining digestate is separated and the dry matter pressed out of a cremation supply system and burned.

Das abgepreßte Gärrestwasser ist mit Ammoniak belastet und wird mittels Strippverfahren von einem hohen Anteil Ammoniak befreit und als Kreislaufwasser dem Prozeß wieder zu­ geführt. Der notwendige Anteil Ausgleichsflüssigkeit wird über Zugabe von frischem Klär­ schlamm über einen Teilstrom erreicht.The extracted digestate water is contaminated with ammonia and is stripped freed from a high proportion of ammonia and returned to the process as circulating water guided. The necessary amount of balancing liquid is obtained by adding fresh clarifier sludge reached via a partial flow.

Statt Klärschlamm können auch andere aufbereitete Flüssigkeitsträger wie z. B. Blutmehl genutzt werden.Instead of sewage sludge, other processed liquid carriers such as. B. blood meal be used.

Das aus der Vergärung entstehende Biogas kann als Energieträger zur Verbrennung des Gärrestes aber auch innerhalb der Strippung bis zur Verdampfung eingesetzt werden.The biogas resulting from fermentation can be used as an energy source to burn the Fermentation residues can also be used within the stripping process until they evaporate.
