Purification of air on pig-rearing farms

Abstract

The purpose. To determine extent of completeness of purification of air and fitness of the developed experimental samples of chamber to their application for decreasing content of polluting gases at air removal from rooms of industrial complex. Methods. Measurement of the content of polluting gases in air before and after passage of air through the chamber of purification. Tests were led in department of fattening pigs of «AgroPrime Holding Ltd.» (Karakurt, Bolgrad region, Odesa oblast). Level of concentration of ammonia and hydrogen sulfide was logged by means of certificated and believed device: multicomponent individual warning device-analyzer of gases «Dozor-S-M». Results. It was established that the level of hydrogen sulfide in air of room at altitude of 0,5 m from floor made 3,34 mg/m3, above manure bath — 9,72, on an entry in the upper filter from below — 2,46, on an entry in the upper filter sideways — 3,03, on an exit of stack of exchange of air on roof — 2,83, and on an entry in the side filter — 5,66 mg/m3. Level of ammonia at altitude of 0,5 m from floor made 1,84 mg/m3, above manure bath — 5,28, on an entry in the upper filter from below — 1,34, on an entry in the upper filter sideways — 1,64, on an exit of stack of exchange of air on roof — 1,54, on an entry in the side filter — 3,08 mg/m3. Hydrogen sulfide and ammonia were not revealed on an exit from air channels with chambers for air filtration. Conclusions. The gained results testify to the following: during tests the air, polluted by stinking gases, after chamber of purification was completely freed from gases. They did not fix both by devices or organoleptically presence of ammonia and hydrogen sulfide. Purification of contaminated air of rooms by means of the developed chamber enables completely delete ammonia and hydrogen sulfide. So, it is possible to ventilate rooms without environmental pollution.
