      <abstract xml:lang="ru">
        <p>По результатам антирейтинга регионов с экстремальным загрязнением водотоков в Свердловской обл. в последние годы фиксируется самое большое число загрязненных рек – более четверти всех высоких и экстремально высоких загрязнений. Одним из источников загрязнения природных водных объектов на Среднем Урале являются закрытые и затопленные медноколчеданные рудники, на которых продолжают формироваться и разгружаться на поверхность кислые шахтные воды. На нескольких из них организован сбор и двухступенчатая система очистки кислых вод, включающая нейтрализацию известковым молоком и отстаивание в пруде-осветлителе. Несмотря на идентичные схемы, при сбросе в водные объекты фиксируются разные показатели загрязняющих веществ. Цель работы – оценка эффективности применяемой системы очистки кислых шахтных вод и выявление параметров, влияющих на качество очищенных шахтных вод. Лабораторные исследования выполнялись с использованием методов пламенно-эмиссионной спектрометрии, пламенной атомно-абсорбционной, атомно-абсорбционной спектрометрии, масс-спектрометрии с ионизацией в индуктивно связанной плазме, потенциометрический и др. Установлено, что на Дегтярском руднике существующая система очистки шахтных вод позволяет значительно снизить концентрации большинства токсичных компонентов шахтных вод практически до нормативных показателей. На Левихинском руднике кратность превышения предельно допустимых концентраций достигает сотни и тысячи раз. Для достижения более высокой степени очистки необходимо, чтобы продолжительность пассивной очистки была достаточной для взаимодействия реагента с кислыми водами. Однако для обеспечения этой возможности потребуется создание каскада прудов площадью несколько тысяч гектаров. Если для Дегтярского рудника действующая двухступенчатая система является достаточно эффективной, то для Левихинского необходим переход на использование более современных систем, включающих три этапа очистки.</p>

        <p>According to the results of the anti-rating of regions with extreme pollution of watercourses in the Sverdlovsk region, the largest number of polluted rivers has been recorded in recent years – more than a quarter of all high and extremely high pollution. One of the sources of pollution of natural water bodies in the Middle Urals are closed and flooded copper-pyrite mines, where acidic mine drainage continue to form and unload to the surface. Several of them have organized collection and a two-stage acidic drainage purification system, including neutralization with lime milk and settling in a clarifier pond. Despite the identical schemes, different indicators of pollutants are recorded during discharge into water bodies. The aim of the work is to evaluate the effectiveness of the applied acid mine drainage purification system and identify the parameters affecting the quality of treated mine water. Laboratory studies were performed using methods of flame emission spectrometry, flame atomic absorption, atomic absorption spectrometry, mass spectrometry with ionization in inductively coupled plasma, potentiometric, etc. It has been established that the existing mine drainage purification system at the Degtyarskii mine makes it possible to significantly reduce the concentrations of most toxic components of mine waters to almost standard values. At the Levikhinskii mine, the multiplicity of exceeding the maximum permissible concentrations reaches hundreds and thousands of times. To achieve a higher degree of purification, it is necessary that the duration of passive purification is sufficient for the reactant to interact with acidic waters. However, to ensure this possibility, it will require the creation of a cascade of ponds with an area of several thousand hectares. If the current two-stage system is quite effective for the Degtyarskii mine, then for Levikhinskii it is necessary to switch to the use of more modern systems, including three stages of purification.</p>
