В качестве ее источника использован электроискровой разряд переменного тока при атмосферном давлении. Типы разряда – стримерный, факельный. Рассмотрено одновременное воздействие электромагнитных полей, заряженных частиц и химически активных соединений, образующихся при электроискровом разряде, на эффективность инактивации патогенной микрофлоры для различных поверхностей (акриловый грунт, эпоксидная смола, лак яхтный, бетонно-графитовая смесь). Обрабатываемый материал (биологический макет подстилочной поверхности пола в птичнике с нанесенным защитным слоем) установлен после электроискровой разрядной камеры, продуваемой плазмообразующим газом (атмосферный воздух). Основными поражающими факторами являются активные химические соединения: озон; свободные радикалы (OH, O, O2), ультрафиолетовое излучение в диапазоне 750–1600 ТГц, электромагнитное излучение от 50 Гц до 980 МГц, заряженные частицы и колебательно возбужденные молекулы азота и кислорода. Получены характеристики плотности потока электромагнитного излучения при электроискровом разряде. По результатам исследований максимальный эффект обработки открытых поверхностей низкотемпературной неравновесной плазмой достигается при использовании в качестве защитного материала поверхностей эпоксидной смолы. Количество инактивированных микроорганизмов при экспозиции 10–20 с достигает 100%. При инактивации микроорганизмов, находящихся на открытых поверхностях, длительность экспозиции экономически нецелесообразно принимать более 20 с. В исследованиях не выявлено существенного различия при использовании стримерного или факельного разрядов для обработки открытых поверхностей помещений.</p></abstract><trans-abstract xml:lang="en"><p>The results of research on inactivation of microorganisms on open surfaces of poultry houses using low-temperature non-equilibrium plasma are presented. AC electrospark discharge at atmospheric pressure was used as its source. Discharge types are streamer, flare. The simultaneous effect of electromagnetic fields, charged particles and chemically active compounds formed by electrospark discharge on the efficiency of pathogenic microflora inactivation for various surfaces (acrylic primer, epoxy resin, yacht varnish, concrete-graphite mixture) is considered. The material to be treated (a biological model of the bedding surface of the floor in the poultry house with the applied protective layer) is installed after the electrospark discharge chamber blown with plasmaforming gas (atmospheric air). The main affecting factors are active chemical compounds: ozone; free radicals (OH, O, O2), ultraviolet radiation in the range of 750–1600 THz, electromagnetic radiation from 50 Hz to 980 MHz, charged particles and vibrationally excited nitrogen and oxygen molecules. Characterizations of electromagnetic radiation flux density at electrospark discharge are obtained. According to the research results, the maximum effect of treatment of exposed surfaces with low-temperature non-equilibrium plasma is achieved when epoxy resin is used as a surface protection material. The number of inactivated microorganisms at exposure of 10-20 s reaches 100%. When inactivating microorganisms on exposed surfaces, it is not economically feasible to take exposure time longer than 20 s. The studies found no significant difference when using streamer or flare discharges to treat outdoor facility surfaces.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>низкотемпературная неравновесная плазма</kwd><kwd>электроискровой разряд</kwd><kwd>микроорганизмы</kwd><kwd>инактивация</kwd><kwd>патогенная микрофлора</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-temperature nonequilibrium  plasma</kwd><kwd>electrospark discharge</kwd><kwd>microorganisms</kwd><kwd>inactivation</kwd><kwd>pathogenic microflora</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Акишев Ю.С.
