Abstract
On the example of LLC "Agroindustrial Complex "Promagro", a list of biological preparations used in the Belgorod region to reduce unpleasant odors from manure effluents has been compiled. In this work, measurements of the content of harmful substances and the level of odors in pig fattening workshops and on the emission of ventilation shafts of pig-breeding complex buildings were carried out: concentrations of carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NO2), sulfur oxide (SO2), methane (CH4), hydrogen sulfide (H2S) and ammonia (NH3), as well as the level of odors in the territories adjacent to the pig complex. The calculation of the dispersion of emissions of harmful and odorous substances in the territories (GOST R 58578-2019 Rules for the establishment of standards and control of emissions into the atmosphere) showed the need to introduce odor destructors into the manure intake baths. In the Belgorod region, the following biological destructors are used at various pig breeding complexes: "Embionic" "Bactofor-3", "Sanvit-K", "Sanvit-K-forte", "Doctor Robik LGN 050", "UBP Bius", "Ecomik Pro V". Among the enterprises actively using "Baktofor-3" is LLC "APK "Promagro", defined as the base. A comparative characteristic of the effectiveness of the drugs was carried out, the optimal concentrations of drugs for the introduction of manure into the baths were determined.
