FIELD: agriculture.
SUBSTANCE: method comprises feeding into the outer chamber of the digestion tank of diluted organic wastes, the process of anaerobic fermentation in the outer and inner chambers of the digestion tank at the temperature of 12-60°C, mixing the fermented mass, removal from the digestion tank of the fermented sludge and selection of biogas from the outer and inner chambers. Prior to the process of fermentation of diluted organic wastes in the outer chamber of the digestion tank the grinding of wastes is carried out by means of ultrasonic vibrations at a frequency of 20±1.5 kHz and intensity of ultrasound from 2 to 5 W/cm2 for 40-60 min.
EFFECT: method provides accelerated processing of solid organic wastes without the loss of finished product quality, increase in the yield of biogas produced without loss of its caloric content, increase in the profitability of production.
