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. The system for continuous disposal of the liquid fraction of cattle manure, including a manure accumulator, at least two bioreactors, a pump, a mixer and blowers, according to the invention, has filter sieves with meshes from 2×2 cm to 5×5 cm for manure with varying degrees of pollution, quarantine sites and tank, manure moistening tank, receiving tank with homogenizer and fecal pump, screw separator, blowers equipped with aerators, irrigation water source, injectors for dosed supply of liquid manure fraction and a pipeline network consisting of gravity pipes through which a receiving tank with a homogenizer and a fecal pump are connected in series, a screw separator for separating manure into solid and liquid fractions, a quarantine tank, bioreactors, injectors for dosed supply manure liquid fraction and a mixer for mixing liquid manure fraction with irrigation water. Between the manure accumulator and the filter screens there are channels made with a slope of 5-10°. The same channels are made between the quarantine sites, the outlet of the filter sieves and the inlet of the manure moistening tank. Blowers with aerators are installed in each bioreactor, supplying air under the level of the liquid manure fraction. The source of irrigation water is connected through pipelines with the inputs of the receiving tank with a homogenizer and a fecal pump and a mixer of irrigation water with a liquid manure fraction, which is also connected through a pipeline with the sprinkling machines of the irrigation system.
EFFECT: invention makes it possible to simplify the process of waste processing to obtain a liquid fraction of manure for disposal by sprinkling and provides 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.
