Abstract

FIELD: anaerobic-aerobic treatment of sewage, poultry and cattle-breeding wastes, human, animal and poultry vital activity products for production of biomethane for agricultural and industrial complexes combining agricultural production with generation of electric and thermal energy and steam during burning solid or liquid nonrenewable fuel. SUBSTANCE: plant has housing 1 with partitions 2 for hydrolytic fermentation chamber 3, acid fermentation chamber 4, acid regression fermentation chamber 5 and alkaline fermentation chamber 6; housing is also provided with mixer located longitudinally and brought in communication with feeder 7 suspended from flexible members 8. Feeder 7 is engageable with vibrator 9; housing is provided with perforated drum 10 where abrasive immobilizing packing 11 is located. Alkaline fermentation chamber 6 is brought in communication with methane fermentation chamber 12 by biogas and mash. Chamber 6 is provided with immobilizing packing made in form of basalt ropes 13 located between biogas inlet branch pipe 14 and outlet branch pipe 15. Pit 16 is located under branch pipe 14. Pit 16 is brought in communication with alkaline fermentation chamber 6 by mash line. Pit 16 is also provided with horizontal drive shaft 17 which holds perforated disks 18 whose lower segments are immersed in mash to create spraying jet in way of motion of biogas. Outlet section of methane fermentation chamber 12 is provided with additional pit 19 which is brought in communication with microfilter 20 and with hydrodynamic, cavitation and thermal disintegrator 21 by methanogen biomass. Disintegrator 21 is brought in communication (by disintegrate) with branch pipe 22 admitting the mash from alkaline fermentation chamber 6 to methane fermentation chamber 12. EFFECT: enhanced efficiency.

Claims (1)

The invention relates to techniques for anaerobic-aerobic treatment of fecal household, poultry, livestock waste and waste products of humans, animals and birds with the production of biomethane and can be used in agro-industrial complexes (AIC), combining agricultural production with the production of electric, thermal energy and steam when burning solid or liquid non-renewable fuels. The inventive biomethane production unit comprises a housing 1 with partitions 2 for chambers 3-6 of hydrolytic, acidic, regression of acidic, alkaline fermentation, respectively, a mixing device located along the housing 1 in the form of a communicating device with a feeder 7, suspended on a flexible element 8, interacting with a vibrator 9 of a perforated drum 10, with a granular abrasive immobilization nozzle 11 placed in its inner cavity, and the alkaline fermentation chamber 6 through biogas and mash is in communication with the methane chamber 12 fermentation and is made with an immobilization nozzle in the form of bundles 13, for example, of basalt fiber placed between the biogas inlet and outlet pipes 14 and 15, respectively, and a pit 16 is placed under the biogas inlet pipe 14, communicated through the mash with the alkaline fermentation chamber 6, with a horizontal drive shaft 17 mounted therein, with perforated disks 18 mounted on the drive shaft 17, immersed in the lower segments by the lower segments and creating a spray torch in the direction of biogas movement, the output section of the chamber Methane fermentation 12 was made with an additional pit 19 connected with a microfilter 20 and methanogen biomass with a hydrodynamic, cavitation, and thermal disintegrator 21, the latter being connected via a disintegrate to a pipe 22 for introducing into the chamber 12 methane fermentation of the mash from chamber 6 of alkaline fermentation.
