PROCEDURE AND DEVICE FOR THE TREATMENT OF UNUSED STRUCTURED BIOLOGICAL WASTE OUDE POOR STRUCTURE

摘要

According to the invention, the unstructured or loosely structured organic waste is comminuted to a maximum grain size of 3 mm and standardized to a homogenous paste (11) with a dry matter content of 5 to 22 % which is then fed to an acidic hydrolysis for a maximum of 24h, after which the paste is subjected to a controlled-temperature methanisation. A vibrating colloid mill is used in the comminution process, a hydrolysis vessel (13), equipped with a vane-type rotary pump, a gas evacuation device and a heating element is used for hydrolysis and for methanisation, an anaerobically operating disc reactor (19) is used which can be heated and fed with gas and which comprises a rotational drive.
