Abstract

L'invention s'utilise dans la détoxication des sédiments provenant des installations d'épuration. Selon cette invention, pour détoxiquer les sédiments provenant des installations d'épuration on détecte la présence de métaux lourds dans ces sédiments et on calcule la quantité nécessaire d'une composition qui comprend de 8,2 à 9,2 % en masse d'hydrates des sels sodiques ou potassiques d'un mélange d'acides aminés; de 3,6 à 4,2 % en masse de peptides, de 0,05 à 0,06 % en masse de peptides, le reste étant constitué d'eau. La composition est obtenue au moyen traitement aquatique et thermique, en présence d'alcalis, de déchets contenant des protéines animales. Les déchets, l'eau et les alcalis sont présents dans des rapports suivants 1: (1,8-2,0): (0,19-0,37), et le traitement est effectué à une température de 120° à 180° C pendant 25 à 90 min.
