PROCESS AND EQUIPMENT FOR THE BIOLOGICAL TREATMENT OF SOLID ORGANIC MATERIAL

摘要

The invention relates to a process for the biological treatment of essentially solid organic material, such as fruit, vegetable and garden waste, wherein the material is successively treated in a hydrolysis tank and in an anaerobic methane reactor, and at least a part of the solids issuing from the hydrolysis tank is treated in a second anaerobic reactor with at least one microorganism of the rumen flora of ruminants; the liquid soluble material produced in the second reactor is further treated in the methane reactor. The material is preferably pretreated mechanically in a destructor. The invention furthermore provides an apparatus for carrying out this process.
