Reducing of Ammonia and Hydrogen Sulfide Emission From Chicken Litter by the Use of Inorganic and Biologically Active Substances

The accumulation of chicken litter, due to the excessive emission of gaseous air pollutants, causes a significant load on the environment. Therefore, the basis of research was to find out the level of NH3 and H2S emission from chicken litter by the influence of inorganic and biologically active substances. It is established that the lowest level of NH3 release from litter - by 25.5-32.6% and H2S by 19.7-24.4% is observed with the introduction of a complex preparation for deactivation of enzymatic processes in chicken litter. Of the studied natural sorbents, the best results for reducing NH3 and H2S emission from the litter were obtained by the use of vermiculite - by 24.4-28.7% and 12.6-15.9%. The biopreparation Kapeliukhiv Yarok more effectively affects the reduction of the NH3 release from the substrate (24.3-27.7%) and the Scarabei - H2S (16.1-19.2%). The introduction in chicken litter magnesium acetate and superphosphate helps to reduce NH3 emission by 22.2-22.8% and 22.3- 24.3%, while H2S by 16.0-19.2% and 16.3-17.2%.
