The basic wastewater treatment system regulated in BAT No. 15 ITC-37–2017 does not ensure water quality meets the discharge standards for fishery water bodies. The gravitational sedimentation method used in this technology is effective for coarse particles. However, colloidal systems formed from fine insoluble fractions are challenging to separate in a gravitational field. As an effective method for removing suspended solids from wastewater, we recommend filtering through a stationary layer of granular filtering materials. The study investigates the kinetics and dynamics of filtering suspended particles from the wastewater of coal enterprises using various filtering materials. Sedimentation curves of suspended solids from quarry wastewater have been constructed. The dependence of wastewater treatment efficiency on the size of filtering material fractions has been identified. The study provides an evaluation of the effectiveness of using natural filtering materials for treating wastewater from coal enterprises. The experiments demonstrated that the most efficient and cost-effective granular filtering material is quartzite from the Bobrovskoye deposit, which we recommend using in a combination of fractions 20–50 and 0.7–12 mm (in a ratio of 1 : 2). The optimal flow rate of wash water during the regeneration of the granular filter is also determined.</p></abstract><trans-abstract xml:lang="ru"><p>Взвешенные вещества являются преобладающими загрязнителями сточных вод угольных предприятий. Базовая система очистки сточных вод, регламентируемая в НДТ № 15 ИТС-37–2017, не обеспечивает качества очистки до нормативных значений сброса в водоемы рыбохозяйственного назначения. Используемый в данной технологии метод гравитационного осаждения в прудах-отстойниках эффективен для грубодисперсных частиц. Однако формирующиеся коллоидные системы из мелкодисперсных нерастворимых фракций являются сложными для разделения в условиях гравитационного поля. В качестве эффективного метода удаления взвешенных веществ из сточных вод рекомендуем использовать фильтрование через стационарный слой фильтрующих зернистых материалов. В работе проведено исследование кинетики и динамики фильтрования взвешенных частиц из сточных вод угольных предприятий на фильтрующих материалах различной природы. Построены кривые гравитационного осаждения взвешенных веществ из карьерных сточных вод. Выявлена зависимость степени очистки сточных вод от размера фракций фильтрующих материалов. В работе приведены результаты оценки эффективности применения фильтрующих материалов природного происхождения для очистки сточных вод угольных предприятий от взвешенных веществ. Результаты экспериментов показали, что наиболее эффективным и доступным зернистым фильтрующим материалом является кварцит Бобровского месторождения, который мы рекомендуем использовать, комбинируя его фракции 2,0–5,0 и 0,7–1,2 (в соотношении 1 : 2). Определена оптимальная скорость подачи промывочных вод на этапе регенерации фильтра с зернистой загрузкой.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>угольные предприятия</kwd><kwd>кварцит</kwd><kwd>взвешенные вещества</kwd><kwd>сточные воды</kwd><kwd>фильтрование</kwd><kwd>механическая очистка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coal enterprises</kwd><kwd>quartzite</kwd><kwd>suspended solids</kwd><kwd>wastewater</kwd><kwd>filtration</kwd><kwd>mechanical treatment</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках комплексной научно-технической программы полного инновационного цикла «Разработка и внедрение комплекса технологий в областях разведки и добычи полезных ископаемых, обеспечения промышленной безопасности, биоремедиации, создания новых продуктов глубокой переработки из угольного сырья при последовательном снижении экологической нагрузки на окружающую среду и рисков для жизни населения», утвержденной Распоряжением Правительства Российской Федерации от 11.05.2022 г. №1144-р, при финансовой поддержке Министерства науки и высшего образования Российской Федерации, № соглашения 075-15–2022-1201 от 30.09.2022 г.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This research was conducted within the framework of the comprehensive scientific and technical program for the full innovation cycle “Development and Implementation of a Complex of Technologies in the Fields of Exploration and Mining of Mineral Resources, Ensuring Industrial Safety, Bioremediation, and Creating New Deep Processing Products from Coal Raw Materials while Sequentially Reducing Environmental Impact and Risks to Population Life” approved by the Government of the Russian Federation Decree No. 1144-r dated 11.05.2022, with financial support from the Ministry of Science and Higher Education of the Russian Federation under Agreement No. 075-15–2022-1201 dated 30.09.2022.</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">Ivanova L.
