The group of inventions refers to the sphere of agriculture and bioenergetics, it can be used in the process of substrate pretreatment for anaerobic digestion of different types of organic waste into eco-friendly and useful substances in a form of fertilizers and biogas with the purpose of biological waste treatment and local stabilization of the ecological situation in the places of its concentration (animal and poultry manure, agricultural and agro-industrial wastes, waste food etc.). The group of inventions includes the substrate pretreatment method for anaerobic digestion of organic wastes and an installation for its realization. The subject matter of this group is characterized in that simultaneously with heating they make degassing of the mixture by means of vacuuming and further treatment with the ultrasonic hydrodynamic radiator energy impact on the mixture flow. Technical result of the group of inventions consists in the increase of substrate quality by means of fine milling, disinfection and homogenization of the mixture - which results in the speed increase of the digestion by 1,5 - 2,0 times and that of the product yield by 2,0 - 2,5 times. |
