Abstract
Przedmiotem zgłoszenia jest sposób unieszkodliwiania odpadów zwierzęcych wysokiego ryzyka, charakteryzujący się tym, że odpad po rozdrobnieniu nie większym niż 3 mm, korzystnie 1 - 2 mm, i zawartości suchej masy od 20% do 60%, miesza się z wodorotlenkiem metalu alkalicznego, w ilości 2 — 10%, najkorzystniej 5% masy odpadu do uzyskania pH mieszaniny powyżej 10, a następnie dodaje się stężonych kwasów mineralnych, korzystnie siarkowego o stężeniu powyżej 70%, korzystnie 85 - 90%, i/lub azotowego o stężeniu powyżej 45 %, korzystnie 50 – 55%, przy czym kwasy dodaje się w ilości co najmniej stechiometrycznej w stosunku do wodorotlenków metali alkalicznych, ale takiej aby uzyskać pH mieszaniny poniżej 4, po czym dodaje się tlenek magnezu, pylisty lub o uziarnieniu poniżej 0,2 mm, w ilości 20 - 60% masy odpadu w przeliczeniu na suchą masę, korzystnie 30 – 50%, a następnie dodaje stężonego kwasu mineralnego, korzystnie jak wyżej siarkowego lub azotowego, w ilości 20 - 60% wsadu z taką szybkością, aby temperatura wzrosła do około 100-150°C przez 30 minut, następnie mieszaninę poreakcyjną schładza się.The subject of the application is a method of neutralizing high-risk animal waste, characterized in that the waste after shredding not larger than 3 mm, preferably 1 - 2 mm, and the dry matter content from 20% to 60%, is mixed with an alkali metal hydroxide in the amount of 2 - 10%, most preferably 5% by weight of the waste to obtain a pH of the mixture above 10, and then concentrated mineral acids, preferably sulfuric acids with a concentration above 70%, preferably 85 - 90%, and / or nitric acids with a concentration above 45%, preferably 50 - 55%, the acids being added in an amount at least stoichiometric to the alkali metal hydroxides, but such that the pH of the mixture is below 4, then magnesium oxide, powdery or grain size less than 0.2 mm, is added in the amount of 20 - 60% of the weight of the waste on a dry basis, preferably 30 - 50%, and then added concentrated mineral acid, preferably sulfuric or nitric acid above, in the amount of 20 - 60% of the charge at this rate After allowing the temperature to rise to about 100-150 ° C over 30 minutes, the reaction mixture is then cooled.
