Детальная информация

В учебном пособии рассмотрены научные разработки коллоидной химии, лежащие в основе методов защиты окружающей среды, к которым относятся методы контроля вредных примесей в различных геосферах Земли, методы их рассеивания в атмосфере и гидросфере и большинство методов очистки газовоздушных выбросов и сточных вод. Учебное пособие на английском языке предназначено для изучения дисциплин «Инженерная защита окружающей среды в строительстве» и «Методы очистки природных и сточных вод» в рамках Международной образовательной программы для магистрантов «Инженерная защита окружающей среды в городском строительстве».

The textbook discusses the scientific developments of colloid chemistry, which underlie the methods of environmental protection, which include methods for controlling harmful impurities in various geospheres of the Earth, methods for their dispersion in the atmosphere and hydrosphere, and most methods of atmospheric discharge purification and wastewater treatment. The textbook in English is intended for studying the disciplines “Engineering environmental protection in construction” and “Methods of water and wastewater treatment” within the framework of the International Educational Program for master’s students “Environmental Engineering in Urban Construction”.
