Изучено несколько типов сточных вод для более полной глубины исследования возможности применения феррата натрия для обеззараживания. Показано, что применение феррата натрия при добавлении 2; 3,5 и 5 об. % от текущего объёма исследуемых образцов сточных вод оказывает высокую инактивацию исследуемой патогенной микрофлоры. Выявлена наиболее эффективная концентрация для практически полного обеззараживания реальной сточной воды мясной промышленности по всем четырём микробиологическим показателям – 5 об. %.</p></abstract><trans-abstract xml:lang="en"><p>The use of sodium ferrate as a disinfectant for industrial wastewater from such groups of pathogenic microorganisms as generalized coliform bacteria (GCB), bacteria of the genus Salmonella, Enterococcaceae and Staphylococcaceae is considered. Several types of wastewater were studied to investigate in more depth the possibility of using sodium ferrate for disinfection. It is shown that the use of sodium ferrate with the addition of 2, 3.5 and 5 vol. % of the current volume of the investigated wastewater samples has a high inactivation of the investigated pathogenic microflora. The most effective concentration for almost complete disinfection of real wastewater from the meat industry for all four microbiological indicators was identified: 5 vol. %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обеззараживание</kwd><kwd>феррат натрия</kwd><kwd>мясная промышленность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>disinfection</kwd><kwd>sodium ferrate</kwd><kwd>meat industry</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">Пальгунов Н.В.
