Beschreibung.Description.
urobporige, sandige Kulturböden benötigen zur Verbesserung ihrer spezifischen Oberflächen und damit auch zur Verbesserung ihrer Wasserhaltefähigkeit eine Zufuhr an Energie.Urobporige, sandy cultivated soils need to improve their specific Surfaces and thus also a supply to improve their water retention capacity of energy.
Aus dem natürlichen Prozeß bei der Methode der Bracheeinschaltung im älteren Ackerbau und den der Natur nadhgeahmten Methoden der Dungzufuhr sowie der aründüngung ist eine derartige Energiezufuhr, wenn auch wenig beachtet, seit langem bekannt.From the natural process of the fallow engagement method in older agriculture and the methods of manure supply imitated by nature as well Such a supply of energy has been a source of energy, even if little attention has been paid to it, since known for a long time.
Von den Pflanzen des "düngenden" Bestandes ebenso wie von den durch die Nutztiere verzehrten - und ihrer energetischen utzbarkeit weitgehend herabgesetzten - Pflanzen ist die jtrahlungsenergie der Sonne in chemische energie umgewandelt worden. Bei deren Zuführung zum Bodensystem - einschließlich seines biologischen Anteils - bleibt diese Energie erhalten.From the plants of the "fertilizing" stand as well as from the through the livestock consumed - and their energetic usability largely reduced - Plants, the sun's radiation energy is converted into chemical energy been. When they are fed to the soil system - including its biological Share - this energy is retained.
Ebenso sind technische Methoden bekannt, bei denen dem Bodensystem Kolloide zugeführt werden, die ihre Entstehung einem endothermen Prozeß verdanken, wie er zum Beispiel bei dem Zusammenschmelzen von Natriumsalzen und Quarz zu löslichem ilatriumsilikat vorliegt. Auch bei dieser Methode muß die dem Bodensystem zugeführte Energie erhalten bleiben und bei den künftigen chemisch-physikalischen Vorgängen in veränderter Form wieder in Erscheinung treten.Technical methods are also known in which the floor system Colloids are added which owe their formation to an endothermic process, as it happens, for example, when sodium salts and quartz melt together to form soluble ones disodium silicate is present. With this method, too, the soil system must be supplied Energy are retained and in the future chemical-physical processes reappear in a different form.
Es darf daher angenommen werden, daß diesem Faktor der bekannten kolloidhaltigen Mittel ein Teil der Wasserkapazitätsverbesserung zugeschrieben werden kann.It can therefore be assumed that this factor is the well-known colloid-containing Means a portion of the water capacity improvement can be attributed.
Es wurde nun gefunden, daß ein Teil der den Abfallstoffen durch ihren organischen Gehalt noch innewohnenden Energie erhalten bleibt, wenn solche Stoffe mit technischer (40-50 os Wasser enthaltender) Phosphorsäure versetzt und ihre Aggregierung mithilfe von Harnstoff und Methylcellulose herbeigeführt wird. Auch das Vorhandensein von Dipoleigenschaften konnte für solche Mischungen festgestellt werden.It has now been found that some of the waste materials by their organic content still inherent energy is retained when such substances mixed with technical (40-50 os water containing) phosphoric acid and their aggregation using brought about by urea and methyl cellulose. Also the presence of Dipole properties could be determined for such mixtures.
Es ist bei dem Verfahren von geringer Bedeutung, ob geringere Mengen von Phosphorsäure zuerst und die aggregierenden Mittel danach in feuchtem Zustand zugemischt werden, oder ob die Klebmittel zuerst in trockenem Zustand einzeln - Harnstoff und Methylcellulose jeweils sehr fein pulverisiert -und eine größere Menge Phosphorsäure mit der entsprechend größeren Wassermenge als letztes Mittel zugemischt werden.It is of little importance in the process whether smaller amounts of phosphoric acid first and the aggregating agents afterwards in a moist state be mixed in, or whether the adhesives are initially dry individually - Urea and methyl cellulose each very finely powdered - and a larger amount Phosphoric acid mixed in with the correspondingly larger amount of water as a last resort will.
Die Methode läßt sich ebenso einfach mit lufttrockenem Ab-Wasserschlamm wie mit torfhaltigem Geflügelkot aus der Geflügelgroßproduktion wie auch mit Peruguano anwenden.The method is just as easy with air-dry sewage sludge as with peat-containing poultry droppings from large-scale poultry production as well as with Peruguano use.
Beispiel 1.Example 1.
loo kg lufttrockener Abwasserschlamm wird mit lo kg fünfundfünfzigprozentiger Phosphorsäure im Mischgerät besprüht und mit schwach angefeuchteter Mischung von 6 kg Methylcellulose und 6 kg Harnstoff im Mischgerät aggregiert.loo kg air-dry sewage sludge becomes fifty-five percent higher with lo kg Phosphoric acid sprayed in the mixer and with a slightly moistened mixture of 6 kg of methyl cellulose and 6 kg of urea aggregated in the mixer.
Beispiel 2.Example 2.
loo kg lufttrockener Abwasserschlamm wird mit je 8 kg fein pulverisierten Harnstoffs und von Methylcellulose sorgfältig vermischt und anschließend im Mischgerät mit 15 bis 20 kg technischer Shosphorsäure - je nach deren Wassergehalt - im Mischgerät besprüht, hierbei aggregiert.loo kg of air-dry sewage sludge is finely pulverized with 8 kg each Urea and methyl cellulose are carefully mixed and then in the mixer with 15 to 20 kg of technical phosphoric acid - depending on its water content - in the mixer sprayed, here aggregated.
Beispiel 3.Example 3.
100 kg Teruguano werden mit je 6 kg Harnstoff und Methyloellulose sorgfältig vermischt und im Mischgerät mit 20 kg 55/obiger hosphorsäure besprüht, wobei die Aggregierung erfolgt..100 kg Teruguano are made with 6 kg each of urea and methyloellulose carefully mixed and sprayed in a mixer with 20 kg 55 / above phosphoric acid, where the aggregation takes place ..
Alle ähnlichen Abfallmaterialien, deren Beseitigung beim Bestreben nach Umweltschutz erforderlich ist, und ebenso alle-konzentrierten tierischen Düngestoffe können nach dem Patentverfahren in verschiedene Kolloidarten enthaltende lagerfähige und streufähige Krümel aggregiert werden, deren fasergehalt physiologische Vorteile bietet.All similar waste materials, their disposal in the endeavor after environmental protection is required, and likewise all-concentrated animal fertilizers can be stored according to the patent process in various types of colloids and scatterable crumbs are aggregated, the fiber content of which has physiological advantages offers.
Alle Verfahren können auch unter Zusatz trockener, streufähiger, löslicher Alkalisilikate in engen zwischen 5 und 20 kg bezogen auf loo kg Hohmaterial durchgeführt werden.All methods can also be used with the addition of drier, more scatterable, more soluble Alkali silicates carried out in close proximity between 5 and 20 kg based on 100 kg of raw material will.
