FIELD: recycling and disposal of waste.
SUBSTANCE: invention relates to a method for disposing of organic waste using an anaerobic digestion apparatus of pig breeding sewage with production of biogas and fertilizers. Device includes a cylindrical sealed container with an opening in the lid for supplying the sewage and a branch pipe in the bottom for the discharge of the liquid fraction with a discharge valve, inclined perforated plate, fixed above the bottom at an angle to the axis of the hollow shaft, nozzles for supplying compressed air from the power source. Nozzles are perpendicularly mounted on the shaft at the same distance from each other and are made in the form of tubes bent at the end at a right angle in a direction opposite to the intended rotation of the shaft due to the energy of the compressed air emerging from the nozzles. Length of the nozzles is increased from top to bottom in the direction of the inclined perforated plate. Angle of inclination of the perforated plate to the axis of the shaft is oriented towards the outlet of the discharge closed conduit to discharge the spent solid fraction of the sludge used as a fertilizer, when rotating the shaft driven by the motor. Discharge pipeline is tilted to its axis, stepped, with the diameter of the steps decreasing in the direction of movement of the spent sludge, and has a discharge device in the form of a shaft with a screw, for the collection of biogas produced during the fermentation process. Under the cover of the tank are installed gas collecting pipes, connected together by means of a common branch pipe.
EFFECT: invention makes it possible to intensify the process of cleaning livestock sewage, while performing water protection measures of the environment.
