APPARATUS FOR ANAEROBIC PROCESSING OF SUBSTRATES INTO BIOGAS AND FERTILISER Russian patent published in 2011 - IPC C02F11/04 

FIELD: chemistry.

SUBSTANCE: invention relates to apparatus for neutralising and recycling highly concentrated organic wastes (deposits, sludge) arising from biological treatment of household waste water or waste water with similar composition. The apparatus for anaerobic processing of organic substrates into biogas and fertiliser has series-arranged collector of the initial substrate 1, hydrolysis apparatus 2, methane tank 6, effluent separator 13, thermal power unit for generating energy from biogas 22 and a boiler for burning solid hydrolysis wastes 17. The hydrolysis apparatus is fitted with an air bubbling device 3, between the methane tank and the effluent separator there is a floatation installation 9, the air bubbling device 10 of which, together with the air bubbling device of the hydrolysis apparatus, is connected to a compressor 19 with a gas-motor drive 20 operating on biogas, wherein the effluent separator 13 and the initial substrate collector are sealed, and their gas space, together the gas space of the hydrolysis apparatus and the floatation installation, is connected through a gas pipe to the gas boiler-recycler 16, which is in turn connected through a circulation line to the boiler for burning solid hydrolysis wastes, the gas-motor drive of the compressor and the thermal power unit for generating energy from biogas.

EFFECT: apparatus increases energy and environmental efficiency of the process of processing organic wastes into biogas and fertiliser.
