Вопросы, связанные с поведением хлора и его соединений в  электросталеплавильной пыли, содержащей цинк и свинец, недостаточно изучены. В работе показано, что опасность наличия хлора и его соединений в шихте, а значит, и в выбросах дуговой сталеплавильной печи (ДСП) заключается в том, что он является основным компонентом, участвующим в формировании высокотоксичных органических веществ – диоксинов и фуранов (ДиФ), которые попадают в окружающую среду не только в газообразном, но и в адсорбированном на частичках пыли виде. По разным данным их концентрация составляет 5  –  500  нг/кг пыли и зависит от технологических параметров плавки. Приведен анализ процессов формирования диоксинов и  фуранов в  ДСП и их поведения в уловленной пыли. Установлено, что при содержании в исследуемой электросталеплавильной пыли 1,3 % хлора, источником поступления которого являются шихтовые материалы, 99,9 % образуют относительно безопасные соединения, в основном хлориды, а небольшая часть идет на образование ДиФ. Количество адсорбированных на поверхности частичек уловленной пыли диоксинов и фуранов составило 474 нг/кг пыли. Являясь сильными экотоксикантами (первый класс опасности), ДиФ повышают класс опасности пыли с четвертого до третьего и выше, что необходимо учитывать при обращении с пылью. Кроме того, транспорт диоксинов и фуранов в окружающей среде осуществляется за счет твердых частиц, сорбирующих яды на своей поверхности, поэтому электросталеплавильная пыль с адсорбированными на ее поверхности ДиФ может спровоцировать их попадание в живые организмы. Рассмотрены пути снижения эмиссии диоксинов и фуранов при производстве электростали и процессы ресурсосберегающей и экологически безопасной переработки пыли. В частности, проанализирована возможность использования известкового молочка для орошения отходящих газов в газоходе ДСП и показано, что это позволит снизить содержание ДиФ до допустимых пределов. Оценена эффективность предлагаемых мероприятий.</p></abstract><trans-abstract xml:lang="en"><p>The use of galvanized scrap as a charge material for electric steel-smelting production leads to the formation of metallurgical dust suitable for the extraction of non-ferrous metals. The issues related to the behavior of chlorine and its compounds in zinc and lead containing EAF-dust is not sufficiently studied. Current research exhibits the danger of chlorine and its compounds in charge and, consequently, in emissions of EAF. Chlorine and its compounds are considered to be the main components associated with the formation of highly toxic organic substances – dioxins and furans (D&amp;F). D&amp;F enter the environment not only in gaseous form, but also in the form of compounds adsorbed on the surface of dust particles. According to various data, D&amp;F concentration is 5-500 ng / kg of dust and depends on the technological parameters of melting. Analysis of the formation processes of D&amp;F in EAF and their behavior in the captured dust is given. It was found that at the studied chlorine content of 1.3% in EAF-dust from the charge materials, 99.9% of chlorine form relatively safe compounds, mainly chlorides, and a small amount goes to the formation of D&amp;F. The amount of D&amp;F adsorbed on the surface of captured dust particles was 474 ng / kg of dust. As strong toxicants, D&amp;F increase the hazard category of dust from the 4th to the 3rd and above that must be considered at dust usage. In addition, the transport of D&amp;F in the environment is due to solid particles that absorb poisons on their surface. Therefore, EAF dust, with D&amp;F adsorbed on its surface, can provoke their entry into organisms. The ways of reducing D&amp;F emission in the production of EAF-steel and the resource-saving and environmentally safe technologies of dust processing are considered. In particular, the possibility of using lime milk for the off-gases irrigation in the EAF gas flue was analyzed and it was shown that it allows to reduce the D&amp;F content to acceptable limits. The efficiency of the proposed activities was evaluated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталеплавильная пыль</kwd><kwd>переработка пыли</kwd><kwd>хлор</kwd><kwd>диоксины</kwd><kwd>фураны</kwd><kwd>хлориды металлов</kwd><kwd>адсорбция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel-making dust</kwd><kwd>dust processing</kwd><kwd>chlorine</kwd><kwd>dioxins</kwd><kwd>furans</kwd><kwd>metal chlorides</kwd><kwd>adsorption</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Фонда содействия инновациям в рамках программы «УМНИК», договор № 12699ГУ/2017</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Foundation of Innovations Promotion for the program UMNIK, the agreement No.  12699GU / 2017.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Основные показатели охраны окружающей среды. 2017: Стат. сб. / Росстат. – М.: 2017. – 115 c.</mixed-citation><mixed-citation xml:lang="en">Osnovnye pokazateli okhrany okruzhayushchei sredy. 2017: Stat. sb. / Rosstat [Main indicators of environmental protection. 2017: Stat. coll. / Rosstat].
