METHOD FOR CONTINUOUS DISPOSAL OF LIQUID FRACTION OF CATTLE MANURE Russian patent published in 2022 - IPC C02F11/04 C02F3/30 C05F3/00 A01C3/00 

FIELD: melioration.

SUBSTANCE: invention relates to the field of melioration and protection of land and water resources and can be used for year-round and continuous utilization of the liquid fraction of manure to improve soil fertility by sprinkling. In the method for continuous utilization of the liquid fraction of cattle manure, which includes obtaining the liquid fraction of manure and its aerobic treatment in bioreactors, according to the invention, manure is filtered from garbage through sieves with meshes of 2×2 cm or 5×5 cm, depending on the contamination of the manure, then it is brought to a moisture content of 88-92% by adding water, homogenized and the manure is separated to separate it into a solid fraction and a liquid one, which is disinfected and sent by gravity to bioreactors for aerobic treatment. After aeration, the liquid fraction of manure is mixed with irrigation water in a ratio of 1:10 and sprinkling is carried out. To ensure continuous disposal of the liquid manure fraction, at least two bioreactors are used, which are alternately filled with the liquid fraction and biofermented for 4-6 months.

EFFECT: invention provides a simplification of waste processing processes in order to obtain a liquid fraction for disposal by sprinkling and the possibility of performing continuous processing of liquid waste for year-round disposal of fertile soils by sprinkling to save their land and water resources.
