      <abstract xml:lang="ru">
        <p>Карьерные сточные воды предприятий горнодобывающей промышленности при открытой добыче железной руды являются источником загрязнения поверхностных водоемов и подземных вод химическими соединениями, используемыми при ведении разработки, в том числе продуктами распада и неполного расходования нитрата аммония при взрывных работах на рудниках – нитратным, нитритным и аммонийным азотом. Такие особенности сточных вод горнодобывающих предприятий, как многотоннажность, дефицит органического вещества и скудность микробиома, необходимо учитывать при выборе способов обезвреживания. Для очистки сточных вод, загрязненных соединениями азота, используют биологические и физико-химические методы. Ряд методов экономически нецелесообразен в связи со значительными объемами образующихся стоков. Важной задачей является поиск экономически обоснованного и высокоэффективного способа очистки карьерных вод от соединений азота. В статье представлены результаты теоретических и экспериментальных исследований возможности применения проницаемого геохимического барьера на основе редокс-системы, состоящей из железного скрапа и углеродсодержащего материала (отсева производства активного угля марки БАУ) для очистки карьерных вод от нитрат-ионов. Термодинамический анализ позволил определить химизм процесса восстановления нитрат-ионов редокс-системой Fe0-C в нейтральной и слабощелочной среде, характерной для карьерных вод. Изучение кинетических закономерностей восстановления нитрат-ионов позволило установить, что скорость процесса описывается уравнением первого порядка. Установлено, что константа скорости восстановления нитрат-ионов возрастает с повышением температуры реакционной смеси: при 278 K – 0,0365 мин–1, 283 K – 0,0416 мин–1, 288 K – 0,0809 мин–1, 293 K – 0,0901 мин–1. Полученные данные позволят обосновать выбор конструкции реактивного барьера или реактора для проведения процесса очистки. Экспериментальные исследования по очистке реальных и модельных карьерных вод на лабораторной установке, имитирующей геохимический барьер, доказали высокую эффективность редукции нитрат-ионов (более 97 %). Очищенная вода отвечает требованиям к сбросу воды в водоемы рыбохозяйственного назначения.</p>

      <abstract xml:lang="en">
        <p>Quarry wastewater from open-pit iron ore mining enterprises is a source of contamination of surface water bodies and groundwater with chemical compounds used during development, including the products of decomposition and incomplete consumption of ammonium nitrate during blasting operations in mines – nitrate, nitrite, and ammonium nitrogen. Such characteristics of mining wastewater as high tonnage, organic matter deficiency, and sparse microbiome must be considered when selecting neutralization methods. Biological and physicochemical methods are used to treat wastewater contaminated with nitrogen compounds. Some methods are economically infeasible due to the significant volumes of wastewater generated. An important task is to find an economically viable and highly effective method for treating quarry water from nitrogen compounds. The article presents the results of theoretical and experimental studies of the possibility of using a permeable geochemical barrier based on a redox system consisting of iron scrap and carbon-containing material (screenings from the production of birch activated charcoal) for treating quarry waters from nitrate ions. Thermodynamic analysis allowed us to determine the chemistry of nitrate ion reduction by the Fe0-C redox system in a neutral and slightly alkaline medium typical of quarry waters. The study of the kinetic patterns of nitrate ion reduction showed that the process rate is described by a first-order equation. It was found that the rate constant for nitrate ion reduction increases with reaction mixture temperature rise: at 278 K – 0.0365 min–1, 283 K – 0.0416 min–1, 288 K – 0.0809 min–1, 293 K – 0.0901 min–1. The data obtained will allow substantiating the choice of the reactive barrier or reactor design for the treatment. Experimental studies on the treatment of real and model quarry waters in a laboratory setup simulating a geochemical barrier proved the high efficiency of nitrate ion reduction (more than 97 %). The treated water meets the requirements for water discharge into fishery water bodies.</p>
