Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania nawozu z ustabilizowanych osadów poprocesowych, polegający na zmieszaniu osadów poprocesowych, z dodatkiem alginianu sodu, oraz roztworu chlorku wapnia, w postaci granulatu, charakteryzuje się tym, że stosuje się osady poprocesowe o uwodnieniu 55 - 94% zawierające węgiel organiczny w ilości 1 - 65% wagowych, korzystnie azot w ilości 0,01 - 15% wagowych, magnez w ilości 0,2 - 10% wagowych, korzystnie fosfor lub korzystnie związki fosforu wyrażonej jako P2O5 w ilości 0,05 - 15% wagowych, korzystnie potas lub korzystnie związki potasu wyrażone jako K2O w ilości 0,01 - 1% wagowych, korzystnie wapno lub korzystanie związki wapna wyrażone jako CaO w ilości 0,1 - 50% wagowych, które miesza się z fosforanem trójsodowym w ilości obliczanej w ten sposób że na 1 g magnezu wyrażonego jako jony Mg2+ dodaje się 0,1 - 10 g fosforanu trójsodowego, a następnie dodaje się alginian sodu i miesza, i tak przereagowaną mieszaninę wkrapla się do roztworu chlorku wapnia lub chlorku baru o stężeniu 1 - 10%, korzystnie 2% i pozostawia aż do utwardzenia powstałych granul, korzystnie w czasie 5 - 30 min. Przedmiotem wynalazku jest także nawóz z ustabilizowanych osadów poprocesowych.The subject of the application is a method of obtaining fertilizer from stabilized post-process sludge, consisting in mixing the post-process sludge with the addition of sodium alginate and a solution of calcium chloride in the form of granules, characterized by the use of post-process sludge with hydration of 55 - 94% containing organic carbon in in an amount of 1 - 65% by weight, preferably nitrogen in an amount of 0.01 - 15% by weight, magnesium in an amount of 0.2 - 10% by weight, preferably phosphorus or preferably phosphorus compounds expressed as P2O5 in an amount of 0.05 - 15% by weight, preferably potassium or preferably potassium compounds expressed as K2O in an amount of 0.01-1% by weight, preferably lime or preferably lime compounds expressed as CaO in an amount of 0.1-50% by weight, mixed with trisodium phosphate in an amount calculated by per 1 g of magnesium expressed as Mg2 + ions 0.1-10 g of trisodium phosphate are added, and then sodium alginate is added and stirred, and the thus reacted mixture is added dropwise to the chloride solution in calcium or barium chloride at a concentration of 1 - 10%, preferably 2%, and it is allowed to harden the resulting granules, preferably for 5 - 30 minutes. The subject of the invention is also fertilizer made of stabilized post-process sludge.
