Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania nawozu organiczno-mineralnego, który prowadzi się tak, że w pierwszym etapie komunalny osad ściekowy ogrzewa się w temperaturze od 55°C do 65°C w czasie od 20 do 30 minut, przy czym podczas ogrzewania stosuje się ciśnienie 0,1 MPa. W drugim etapie do ogrzanego osadu ściekowego dodaje się diatomit w ilości od 0,25 do 1,5 kg na 1 kg suchej masy osadu ściekowego i prowadzi się ich mieszanie. W trzecim etapie prowadzi się formowanie granulatu, zaś w czwartym etapie granulat suszy się w temperaturze od 60°C do 85°C w czasie od 30 do 60 minut, a następnie w piątym etapie granulat kruszy się. Zgłoszenie obejmuje także nawóz organiczno-mineralny, który wytworzony jest z ustabilizowanego osadu ściekowego oraz pylistego diatomitu i po wysuszeniu ma on postać granulatu, a ponadto zawiera on przyswajalne formy substancji organicznych, azotu, fosforu i potasu.The subject of the application is a method of producing an organo-mineral fertilizer, which is carried out in such a way that, in the first stage, the municipal sewage sludge is heated at a temperature of 55 ° C to 65 ° C for 20 to 30 minutes, with a pressure of 0 being used during heating. , 1 MPa. In the second stage, kieselguhr in the amount of 0.25 to 1.5 kg per 1 kg of dry weight of the sewage sludge is added to the heated sewage sludge and mixed. In the third step, the formation of the granules is carried out, in the fourth step, the granules are dried at a temperature of 60 ° C to 85 ° C for 30 to 60 minutes, and then in the fifth step, the granules are crushed. The application also covers an organic-mineral fertilizer, which is made of stabilized sewage sludge and powdery diatomite, and after drying it is in the form of granules, and also contains available forms of organic substances, nitrogen, phosphorus and potassium.
