FIELD: agriculture.

SUBSTANCE: method for utilizing the liquid fraction of manure drains from pig-breeding farms includes separating the manure, introducing a chemical reagent into the liquid manure fraction, and stirring the mixture. For the purpose of utilizing the liquid fraction of the manure drains from pig-breeding farms, reducing the concentration of organic and inorganic pollutants, the aqueous solution of sodium hypochlorite is introduced in the active chlorine concentration equal to 185 g/l, equivalent to the sum of the concentration of organic components. Thereinafter carbonic acid is added until the neutral acidity of the medium is achieved, and then the cleaned sewage is mixed with the river water at the ratio of 1:10 and discharged into a river basin.
