FIELD: chemistry.
SUBSTANCE: invention relates to field of processing organic substrates with humidity 95-97% with concentration of organic substance not less than 20 g/l. Such substrates are represented by semi-liquid and liquid manure, formed in the process of self- floating manure removal, primary precipitation and condensed active sludge from constructions of mechanical-biological purification of household sewages (at city purification constructions) and discharges after processing of agricultural production. Apparatus consists of anaerobic section with descending ceiling and immobilising regular nozzle with zones of biomass clarification and condensing with mixing device, located in lower part of section. Clarification zone is hydraulically connected with input of anaerobic biofilter. Anaerobic biofilter is located coaxially inside anaerobic section case with common gas part. Immobilising regular nozzle is made in form of assemblage of rods with possibility of rotation. Anaerobic section is coaxially placed into aerobic section case, whose output has hydraulic connection with anaerobic section.
EFFECT: intensification of combined aerobic-anaerobic process, increase of energy efficiency of methane generation process and improvement of mass and size characteristics of device.
