  Verfahren zur Herstellung eines Diingemittels aus Schlick. 



   Es ist bekannt, dass der Schlick der Salz-und Süsswasser einen hohen Düngewert hat. Besonders der   l\1eeresschlick   wird seit langer Zeit in vielen Küstenorten als Dünger benutzt. Sein hoher Wassergehalt steht aber einem Versand   auf grösseren Strecken   entgegen. Um den Meeresschlick in weiteren Kreisen als Düngemittel zugänglich machen zu können, ist es daher erforderlich, ihn möglichst von seinem Wassergehalt zu befreien. Diese Aufgabe bietet aber Schwierigkeiten. Versucht man, den Schlick bei Temperaturen über 300 C zu trocknen, so tritt an seiner Oberfläche eine Krustenbildung ein, die den Austritt des Wassergehaltes aus seinem Innern erschwert. 



   Um ein vollständiges Austrocknen des Schlicks zu erreichen, müssten daher sehr hohe Temperaturen angewendet werden. Hiebei würden aber die wertvollen,   ursprünglich   kolloidalen   Eigenschaften   des Schlicks verlorengehen. Es entsteht bei solchen Temperaturen eine bröckelige Masse von zementartiger Beschaffenheit, in welcher die kolloidale Form der bis zu 40%   und darüber im Selhliek enthaltenen Kiesel-   säure grösstenteils zerstört ist. Auch die wertvollen Bakterien des   Schlicks   werden bei   Anwendung hoher   Temperaturen vernichtet. 



   Gemäss vorliegender Erfindung geschieht das Austrocknen des   Schlicks   ohne Anwendung hoher Temperaturen dadurch, dass er mit Torf oder anderen   geeigneten humosen   Stoffen, eventuell diese in hydrolysierter Form, wie bekannt, herzustellen mittels chemischer Solventien, Druck und Erhitzung,

  Process for the manufacture of a detergent from silt.



   It is known that the silt of salt and fresh water has a high fertilizer value. The sea silt in particular has been used as fertilizer in many coastal towns for a long time. However, its high water content prevents it from being shipped over longer distances. In order to be able to make the sea silt available as fertilizer in wider circles, it is therefore necessary to free it of its water content as far as possible. But this task presents difficulties. If you try to dry the silt at temperatures above 300 C, a crust formation occurs on its surface, which makes it difficult for the water content to escape from its interior.



   In order to achieve complete drying out of the silt, very high temperatures would therefore have to be used. In doing so, however, the valuable, originally colloidal properties of the silt would be lost. At such temperatures, a crumbly mass of cement-like consistency is created in which the colloidal form of the silica contained in the Selhliek up to 40% and above is largely destroyed. The valuable bacteria in the silt are also destroyed when high temperatures are used.



   According to the present invention, the silt is dried out without the use of high temperatures by making it with peat or other suitable humic substances, possibly in hydrolyzed form, as known, by means of chemical solvents, pressure and heating,

 impairing its valuable properties.
