METHOD FOR ANAEROBIC PROCESSING OF LIQUID ORGANIC WASTES WITH OZONE PRETREATMENT IN A VORTEX LAYER APPARATUS Russian patent published in 2023 - IPC C02F11/04 C02F3/28 

FIELD: concentrated organic substrates utilization.

SUBSTANCE: invention relates to the field of utilization of concentrated organic substrates suitable for further use in production conditions - their sources or in related fields. The method for anaerobic processing of liquid organic waste includes pretreatment of waste in a vortex bed apparatus, fermentation in a digester, separation of the fermented mass into fractions. Ozone-containing air with an ozone concentration of 70 mg/l is additionally supplied to the working chamber of the vortex layer apparatus at a rate of 20 l/min. Pre-treatment is carried out in the working chamber of the vortex layer apparatus for 0.5 min at a magnetic field rotation frequency of 50 Hz. The thermal energy generated as a result of the operation of the vortex layer apparatus is used to ensure the thermophilic temperature regime of the digester.

EFFECT: increasing the efficiency of anaerobic processing of liquid organic waste.
