METHOD FOR CONTINUOUS REMOVAL AND PROCESSING OF MANURE EFFLUENTS OF LIVESTOCK BUILDINGS FOR FARM ANIMALS Russian patent published in 2024 - IPC C02F11/02 A01C3/00 

FIELD: protection of land and water resources.

SUBSTANCE: invention can be used for year-round and continuous removal of manure from premises containing farm animals, and preparation for disposal of liquid fraction of manure on agricultural landscapes. Manure is accumulated in a container with a gravity channel with slope of 5–10 degrees, filtered from debris through sieves with cells measuring 2×2 cm or 5×5 cm, moistened, fed by gravity for homogenisation, separation into solid fraction and liquid fraction. Liquid fraction is sent by gravity for aerobic treatment in bioreactors. In addition, according to the number of livestock premises there are tanks for manure accumulation with outlet controlled gravity channels and a main tray. After aeration, a stream of liquid fraction is fed back from the bioreactor into the tray at pressure of 0.3–0.4 MPa. As an agent providing reverse supply of liquid fraction, used for manure moistening and loosening in the main tray coming from gravity channels, a return pipeline is used, which on one side is connected to the main tray, and on the other—to the bioreactor, and is located parallel to the main tray. Additional channels with slotted nozzles are laid between the return pipeline and the main tray. Slotted nozzles are coupled with gravity channels. One of the slotted nozzles is located at the bottom and at the beginning of the main tray at the point of its connection with the return pipeline.

EFFECT: increased efficiency of continuous removal of manure runoff from premises containing animals, preservation of land and water resources.
