Abstract
Ujawniono sposób wytwarzania nawozu z osadów ściekowych, przeznaczony do poprawienia struktury gleby w zastosowaniach rolniczych, charakteryzujący się tym, że do osadów ściekowych o zawartości powyżej 17% suchej masy dodaje się od 1% do 5%, korzystnie 2,5%, lepiszcze w postaci mąki i dokładnie się miesza z kolei dodaje się wapna palonego od 1% do 5%, korzystnie około 3%, oraz bentonitu suszonego od 30% do 70%, korzystnie około 50%, i tak wytworzoną mieszaninę po zgęstnieniu granulujemy mechanicznie. Następnie suszymy gorącymi gazami o temperaturze powyżej 50°C od punktu rosy do wymaganej twardości.A method for producing fertilizer from sewage sludge is disclosed, which is intended to improve soil structure in agricultural applications, characterized in that sewage sludge with a content of more than 17% of dry matter is added from 1% to 5%, preferably 2.5%, a binder in the form of flour and thoroughly mixed, in turn, quicklime is added from 1% to 5%, preferably about 3%, and dried bentonite from 30% to 70%, preferably about 50%, and the mixture thus obtained is mechanically granulated. Then we dry with hot gases at a temperature above 50 ° C from dew point to the required hardness.
