Abstract

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%.

利用无机和生物活性物质减少鸡粪中氨和硫化氢的排放

由于气态空气污染物的过量排放，鸡粪的堆积对环境造成了巨大的负荷。因此，研究的基础是在无机和生物活性物质的影响下，找出鸡粪中 NH3 和 H2S 的排放水平。研究结果表明，在使用一种复合制剂使鸡粪中的酶过程失活后，鸡粪中的 NH3 排放量最低，为 25.5-32.6%，H2S 排放量最低，为 19.7-24.4%。在所研究的天然吸附剂中，使用蛭石减少鸡粪中 NH3 和 H2S 排放的效果最好，分别减少了 24.4-28.7% 和 12.6-15.9%。Kapeliukhiv Yarok 生物制剂能更有效地减少基质中的 NH3 排放量（24.3-27.7%）和 Scarabei - H2S 排放量（16.1-19.2%）。在鸡粪中引入醋酸镁和过磷酸钙有助于减少 22.2-22.8% 和 22.3-24.3% 的 NH3 排放，以及 16.0-19.2% 和 16.3-17.2% 的 H2S 排放。
