FIELD: agriculture. SUBSTANCE: method involves preliminary and final dehydration of livestock wastes; providing preliminary dehydration by filtering within centrifugal force field relative to motion of livestock waste at separation factor of 80-150; providing final dehydration by centrifuging through filtering partition wall at maximum separation factor of 300-350 with following obtaining of solid fraction; discharging filtrate produced after preliminary and final dehydration processes into anaerobic pond; subjecting anaerobic silt, produced in anaerobic pond due to fermentation, to vacuum filtration dehydration or centrifuging via sediment layer and mixing with solid fraction. Method may be used for reprocessing of sewage water from pig farms and cattle farms.
