Abstract
Description
Die Erfindung betrifft ein Verfahren und Einrichtungen zur Stabilisierung von Stickstoffdünger in organischen Restprodukten in flüssiger Phase (Suspension, Emulsion, Lösung) wie Gülle, Gülle-Mistgemischen, Restbrühen (fermentiertes Substrat) aus Biogasanlagen. Die Stabilisierung erfolgt durch die Umsetzung des in den Restprodukten vorliegenden Ammoniumhydrogenkarbonats mit mineralischen Säuren vorzugsweise Schwefelsäure, Phosphorsäure, Kieselsäure und oder Gemischen dieser Säuren in nicht flüchtige Salze dieser Säuren.The The invention relates to a method and devices for stabilization of nitrogen fertilizer in organic residues in liquid Phase (suspension, emulsion, solution) such as manure, Slurry manure mixtures, residual brews (fermented Substrate) from biogas plants. The stabilization takes place through the implementation of the ammonium bicarbonate present in the residual products with mineral acids, preferably sulfuric acid, Phosphoric acid, silica and or mixtures of these acids into non-volatile salts of these Acids.
Die Landwirtschaft trägt mit über 80% zu den Ammoniak-Emissionen (NH3) in Deutschland bei, wobei auf die Lagerung und Ausbringung von Gülle ca. 60% der Ammoniak-Emissionen entfallen. Durch das erfindungsgemäße Verfahren werden die Ammoniak-Emissionen drastisch reduziert. Um nach dem Stand der Technik die Ammoniumverluste zu reduzieren muss die Gülle oder die Restbrühe aus Biogasanlagen unmittelbar nach der Ausbringung in den Boden eingearbeitet werden. Liegt das Ammoniak in der Form von nicht flüchtigen Ammoniumsalzen vor, dann ist dieser Arbeitsgang nicht erforderlich und die erfindungsgemäß behandelte Gülle oder die Restbrühen aus Biogasanlagen können auch als Kopfdünger (Oberflächendüngung) eingesetzt werden.The Agriculture accounts for over 80% of ammonia emissions (NH3) in Germany, taking care of storage and application of manure account for about 60% of ammonia emissions. By the Processes according to the invention are the ammonia emissions drastically reduced. To the state of the art, the ammonium losses The liquid manure or the remaining broth must be reduced from biogas plants immediately after application to the soil be incorporated. Is the ammonia in the form of non-volatile Ammonium salts before, then this operation is not required and the manure treated according to the invention or the residual brews from biogas plants can also used as topical fertilizer (surface fertilization) become.
Es
sind zahlreiche Verfahren zur Fixierung und oder Abtrennung des
in wasserlösicher Form vorliegenden Stickstoffdüngers
in der Gülle oder den Restbrühen aus den Biogasanlagen
bekannt. So wurde vorgeschlagen, den wasserlöslichen Stickstoffdünger
durch Ad-/Absorption an Humus zu binden. Siehe dazu
Andere
Verfahren schlagen vor durch die Zugabe von Gips und Tonmehl oder
Stroh das Ammoniak entweder chemisch oder adsorptiv zu binden. Siehe
dazu:
In
weiteren Verfahren wird vorgeschlagen das Ammoniak aus den biologischen
Reststoffen durch Ausdampfen abzutrennen und dann in nicht flüchtige
Salze zu überführen; siehe
Alle diese Verfahren haben den Nachteil, dass sie entweder keine vollständige Fixierung des Ammoniakdüngers erreichen, oder technisch aufwändig sind und ökonomisch nur in Grossanlagen zu betreiben sind.All These methods have the disadvantage that they are either not complete Achieve fixation of the ammonia fertilizer or technically are complex and economical only in large plants to operate.
Ziel dieser Erfindung ist, durch eine dezentrale Behandlung der biologischen Reststoffe den Stickstoffkreislauf in landwirtschaftlichen Betrieben und bei Betreibern von Biogasanlagen weitgehend zu schließen, womit weniger Mineraldünger eingesetzt werden muss und die Ammoniak-Emissionen drastisch reduziert werden.aim this invention is, by a decentralized treatment of biological Residues the nitrogen cycle in farms and close to operators of biogas plants, with which less mineral fertilizer must be used and the ammonia emissions are drastically reduced.
Erfindungsgemäß gelingt dies dadurch, dass die biologischen Reststoffe im Falle von Gülle oder Gülle-Mistgemischen mit einem pH-Wert von ca. 6,5 mit mineralischen Säuren, vorzugsweise konz. Schwefelsäure auf einen pH-Wert von 5,7 eingestellt werden, entspricht dem pK-Wert von (NH4)2SO4. Das dabei entstehende CO2 entweicht und führt zur Schaumbildung. Während der Zugabe der mineralischen Säure ist die Gülle im Güllelager gut zu durchmischen, was entweder durch (vorhandene) Propellerrührer mit Anschluss an den Trecker oder durch Flüssigkeitsstrahl-Mischer erreicht werden kann. Die konz. Schwefelsäure wird durch eine Flüssigkeitsstrahl-Flüssigkeitspumpe – betrieben mit Druckwasser von 3,5 bis 5 bar – eingebracht, wodurch sie mit einer Konzentration von 20–30% zum Einsatz kommt. Eine intensive Durchmischung der Gülle bei dieser Operation ist anzustreben, damit eine schnelle und gleichmäßige Verteilung der Schwefesäure z. B. in einem 500 cbm Güllelager erreicht wird und das entstehende CO2 schnell entweichen kann. Der Zeitaufwand für diese Operation in einem 500 cbm Güllelager beträgt ca. 2 Stunden.According to the invention succeeds this is due to the fact that the biological residues in the case of manure or slurry manure mixtures with a pH of about 6.5 with mineral acids, preferably conc. sulfuric acid adjusted to a pH of 5.7, corresponds to the pK value of (NH4) 2SO4. The resulting CO2 escapes and leads for foaming. During the addition of the mineral Acid is the manure in the manure storage well to be mixed, either by (existing) propeller stirrer with connection to the tractor or by liquid jet mixer can be achieved. The conc. Sulfuric acid is going through a liquid jet liquid pump - operated with pressurized water of 3.5 to 5 bar - introduced, thereby It is used with a concentration of 20-30%. An intensive mixing of manure during this operation is to strive for a fast and even Distribution of the sulfuric acid z. B. in a 500 cbm slurry storage is achieved and the resulting CO2 can escape quickly. Of the Time spent on this operation in a 500 cbm slurry store is about 2 hours.
Die erfindungsgemäße Behandlung von Restbrühen aus Biogasanlagen erfolgt analog der bei Gülle, mit dem Unterschied, dass die Restbrühen aus Biogasanlagen in der Regel einen höheren Anteil an wasserlöslichem Stickstoffdünger haben, d. h. mit einem pH-Wert von ca. 8,0 anfallen. Die Restbrühe wird mit mineralischen Säuren, vorzugsweise mit konz. Schwefelsäure auf einen pH-Wert von 5,7 entsprechend dem pK-Wert des (NH4)2SO4 eingestellt. Der wasserlösliche Stickstoffdünger liegt dann als Ammonsulfat (AS) vor und wirkt nach der Ausbringung wie der analoge Mineraldünger als Kopfdünger. Die Operation kann im Lagerbehälter unmittelbar vor der Ausbringung zwei mal im Jahr – Frühjahr und Herbst – durchgeführt werden. In den Fällen, wo aus dem Lager Restbrühe in den Fermenter der Biogasanlage rezirkuliert wird, ist die Behandlung der Restbrühe in einem separaten Behälter vorzunehmen, um ein Einschleppen von Sulfat in den Fermenter zu vermeiden.The Inventive treatment of residual broths From biogas plants is analogous to the manure, with the Difference that the residual broth from biogas plants in the Usually a higher proportion of water-soluble Have nitrogen fertilizer, d. H. with a pH of approx. 8.0. The residual broth is mixed with mineral acids, preferably with conc. Sulfuric acid to a pH of 5.7 adjusted according to the pK value of (NH4) 2SO4. Of the water-soluble nitrogen fertilizer is then as ammonium sulfate (AS) before and acts after the application as the analog mineral fertilizer as a topical fertilizer. The operation can take place in the storage container just before application twice a year - spring and fall - be carried out. In cases, where from the stock residual broth in the fermenter of the biogas plant is the treatment of the residual broth in a separate container to make a tow to avoid sulfate in the fermenter.
Das erfindungsgemässe Verfahren gestattet auch biologische Reststoffe in Lagunen, für die eine Abdeckung sehr aufwändig ist so zu betreiben, dass bei der Lagerung keine Ammoniak-Emissionen auftreten. Dazu werden die Lagerbrühen bis kurz vor der Ausbringung bei einem pH-Wert von 4,0–5,5 vorzugsweise bei 5,0 gehalten. Damit wird unterbunden, dass während der warmen Sommerzeit die methanogenen Microorganismen, die nicht nur organische Säuren sondern auch Sulfate abbauen können, aktiv werden.The inventive method also allows biological residues in lagoons, for which a cover is very expensive to operate so that no ammonia emissions occur during storage. For this purpose, the stock brews are kept at 5.0 until shortly before application at a pH of 4.0-5.5. This will be prevented that during the warm summertime, the methanogenic microorganisms, which can degrade not only organic acids but also sulfates, become active.
Nach dem erfindungsgemäßen Verfahren kann bei Böden, die bei Maisanbau eine Düngung mit Handelsdünger wie z. B. Diaminphosphat (DAP) benötigen, die Gülle oder die Restbrühe aus der Biogasanlage mit Phosphorsäure auf den entsprechenden pH-Wert eingestellt und unmittelbar vor der Maisaussaat ausgebracht werden. Der Stickstoffdünger liegt dann bereits als DAP in der behandelten Gülle bzw. in der Restbrühe aus der Biogasanlage vor.To the process according to the invention can be applied to soils the maize cultivation fertilization with commercial fertilizer such as As diamine phosphate (DAP), the manure or the residual broth from the biogas plant with phosphoric acid adjusted to the appropriate pH and immediately before the Corn sowing be applied. The nitrogen fertilizer is lying then already as DAP in the treated manure or in the Remainder broth from the biogas plant before.
Die Vorteile des erfindungsgemäßen Verfahrens liegen darin, dass der wasserlösliche Stickstoffdünger in der Gülle bzw. im Restsubstrat aus den Biogasanlagen je nach Bedarf entweder mit Schwefelsäure oder mit Phosphorsäure behandelt wird, wobei der wasserlösliche, schnell verfügbare Stickstoffdünger entweder als AS oder als DAP vorliegen und kein zusätzlicher Mineraldünger notwendig ist. Die wasserunlöslichen Anteile an Stickstoffdünger liegen in Form von Proteinen vor, die den Charakter eines Langzeitdüngers haben. Ein weiterer Vorteil dieser Verfahrensweise ist, dass es bedarfsgerecht eingesetzt und dezentral – vor Ort – durchgeführt werden kann. Daraus ergeben sich kurze Transportwege für den An- und Abtransport von biologischen Reststoffen.The Advantages of the method lie in that the water-soluble nitrogen fertilizer in the manure or in the residual substrate from the biogas plants as required either with sulfuric acid or with phosphoric acid the water-soluble, readily available Nitrogen fertilizer either AS or DAP present and no additional mineral fertilizer necessary is. The water-insoluble components of nitrogen fertilizer are in the form of proteins that have the character of a long-term fertilizer to have. Another advantage of this procedure is that it used as required and decentralized - on site - carried out can be. This results in short transport routes for the Transport and removal of biological residues.
