Abstract
The aim. To determine the degree of completeness of air purification and the
suitability of the developed experimental samples of the chamber for its use to reduce
the content of polluting gases during the removal of air from the premises of the
industrial complex. Methods. The research was conducted on the basis of the pig farm
of Agroprime Holding LLC of the Odesa region. The determination of the level of
methyl mercaptan (mg/m3) in air emissions outside the premises was carried out using
a portable gas analyzer Dräger X-am 5600. The determination of the level of ammonia
(mg/m3), hydrogen sulfide (mg/m3) was carried out using a portable multi-component
gas analyzer ANKAT - 7664 Micro. The measurement of the content of polluting gases
in the air before and after passing the air through the purification chamber was carried
out in the pig fattening shop of the pig complex. The concentration level of ammonia
and hydrogen sulfide was recorded using a certified and certified device: a multicomponent
individual alarm-analyzer of gases "DOZOR-S-M". The results. It was
established that the level of hydrogen sulfide in the air of the room at a height of 0.5 m
from the floor was 3.34 mg/m3, above the manure bath – 9.72, at the entrance to the
upper filter from below - 2.46, at the entrance to the upper filter from the side – 3.03, at
the exit from the air exchange shafts on the roof – 2.83, and at the entrance to the side
filter – 5.66 mg/m3. The level of ammonia at a height of 0.5 m from the floor was
1.84 mg/m3, above the manure bath – 5.28, at the entrance to the upper filter from
below – 1.34, at the entrance to the upper filter from the side – 1.64, at the exit from the
air exchange ventilation shaft on the roof – 1.54, at the entrance to the side filter –
3.08 mg/m3. Hydrogen sulfide and ammonia were not detected at the exit from the
ventilation ducts, where air purification chambers were installed. Conclusions. The
obtained results indicate that, during the tests, the air contaminated with foul-smelling
gases, after passing through the purification chamber, was completely freed from gases,
and the presence of ammonia and hydrogen sulfide was not detected either by
apparatus or organoleptically. Purification of polluted indoor air with the help of a
developed chamber makes it possible to completely remove ammonia and hydrogen
sulfide. Therefore, it is possible to ventilate the premises without polluting the
environment.
Key words: pig complex, pig farm, air pollution, hydrogen sulfide, ammonia, air
purification, ecological state of the environment.
