При этом повышение концентрации соединений азота в водной среде может представлять определенную опасность для экосистемы. Если эффективность очистки сточных вод от соединений азота на станции очистки сточных вод не обеспечивается, в поверхностных водах водоемов начинается процесс эвтрофикации, который сопровождается стимуляцией роста водорослей. Процесс глубокой очистки сточных вод от питательных веществ и биогенных элементов, особенно от аммонийного азота и соединений азота, - основная задача станции очистки сточных вод в современном мире. За счет создания аэробной и аноксидной среды в сооружениях со взвешенным активным илом реализуются биохимические реакции нитрификации и денитрификации. Для увеличения эффективности очистки сточных вод от соединений азота с применением взвешенной микрофлоры необходимо определение влияния технологических параметров -- водородного показателя pH, концентрации растворенного кислорода и окислительно-восстановительного потенциала (ORP) на процесс глубокой биологической очистки.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. </p><p>С целью определения влияния технологических параметров на скорость нитрификации и денитрификации в биологическом реакторе проведены эксперименты, направленные на решение поставленных задач по каждой реакции.</p></sec><sec><title>Результаты</title><p>Результаты. </p><p>Получены значения удельной скорости нитрификации при оптимальном значении pH реактора.

Due to creating an aerobic and anoxic media in structures with suspended activated sludge, biochemical reactions of nitrification and denitrification are realized. To increase the efficiency of wastewater treatment from nitrogen compounds using suspended microflora, it is necessary to determine the influence of technological parameters - hydrogen ion concentration, dissolved oxygen level and oxidation-reduction potential (ORP) on the integrated biological wastewater treatment process.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. </p><p>Experiments aimed at solving the problems posed for each reaction were conducted in order to determine the influence of technological parameters on the rate of nitrification and denitrification in a biological contact reactor.</p></sec><sec><title>Results</title><p>Results. </p><p>As a result of the experiment, the values of the specific rate of nitrification with the optimal pH value of the reactor were obtained. For the denitrification process, the ratio between the dissolved oxygen level, the ORP, and the specific denitrification rate are estimated.</p></sec><sec><title>Conclusions</title><p>Conclusions. </p><p>It was shown that the pH value, dissolved oxygen level and ORP play a significant part in the process of integrated wastewater treatment from nitrogen compounds.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глубокая биологическая очистка от соединений азота</kwd><kwd>денитрификация</kwd><kwd>математическое описание</kwd><kwd>нитрификация</kwd><kwd>очистка сточных вод</kwd><kwd>реактор периодического действия</kwd><kwd>реконструкция станции очистки сточных вод</kwd><kwd>технологические параметры</kwd><kwd>удельные скорости денитрификации</kwd><kwd>удельные скорости нитрификации</kwd><kwd>Integrated biological wastewater treatment from nitrogen compounds</kwd><kwd>denitrification</kwd><kwd>mathematical description</kwd><kwd>nitrification</kwd><kwd>wastewater treatment</kwd><kwd>batch reactor</kwd><kwd>reconstruction of wastewater treatment plant</kwd><kwd>technological parameters</kwd><kwd>specific denitrification rate</kwd><kwd>specific nitrification rate</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">Воронов Ю.В., Яколев С.В.
