Abstract
Background: The research on optimal composition of chemical reagents for deodorization and disinfection of liquid manure slurry of pig breeding complex facility was performed. Results: It was established, that all three compositions (sulfuric acid combined with sodium hypochlorite, ammonium persulphate in combination with peracetic acid, and also the mixture of sodium nitrite and ammonium molybdate) provide the removal of unpleasant odors, however, more preferable from the point of preservation of disinfecting effect, are the mixtures containing ammonium persulphate plus peracetic acid and sodium nitrite combined with ammonium molybdate (high deodorizing and disinfecting effect was observed after 21 days). Conclusion: Manure mixtures obtained as a result of such treatment are harmless for the environment and could be used as a main component of organo-mineral fertilizers.
