Приводятся результаты исследования применения биомассы микроводоросли C. kessleri в качестве биосорбента для очистки модельных сточных вод от ионов Cu2+ в статических условиях. Биосорбция – перспективная технология очистки промышленных стоков, содержащих в себе различные соединения тяжелых металлов, однако вопросы экономической выгоды использования биосорбентов, их экологическая безопасность и стоимость утилизации отработанных сорбентов подвергаются большому обсуждению. Предлагается утилизировать отработанный биосорбент, образующийся после очистки сточных вод от меди как дополнительное топливо. Концентрация меди в фильтрате определена методом колориметрического анализа с диэтилдитиокарбаматом натрия. Эффективность очистки и сорбционная емкость сухой массы C. kessleri получена расчетным путем. Максимальная сорбционная емкость к ионам Cu2+ составила 4.2 мг/г. Эффективность очистки достигала 87% при начальной концентрации ионов Cu2+ = 97 мг/л. Испытания по определению удельной теплоты сгорания биомассы C. kessleri и отработанных биосорбентов на ее основе проведены калориметрическим методом при помощи калориметра бомбы. Удельная теплота сгорания равна 22125 и 21674 кДж/кг соответственно. Приведено сравнение данных величин с традиционными энергоносителями. Разработана технологическая схема безотходного цикла использования C. kessleri для очистки сточных вод промышленных предприятий с получением в качестве конечных продуктов нескольких ценных ресурсов, таких как очищенная вода, энергетические р</p></abstract><trans-abstract xml:lang="en"><p>The use of microalgae Chlorella kessleri VKPM A1-11 ARM (RF, NPO Algobiotechnology) for environmental and energy purposes is considered. The results of our study of the use of C. kessleri microalgae biomass as a biosorbent to purify model wastewater from Cu2+ ions under static conditions are presented. Biosorption is a promising technology for the treatment of industrial effluents containing various heavy metal compounds, but the issues of economic benefits of using biosorbents, their environmental safety and the cost of disposal of used sorbents are subject to much discussion. The paper proposes to dispose the used biosorbent formed after wastewater treatment from copper as an additional fuel. The copper concentration in the filtrate was determined by colorimetric analysis with sodium diethyldithiocarbamate. The cleaning efficiency and sorption capacity of the dry mass of C. kessleri were obtained by calculation. The maximum sorption capacity for Cu2+ ions was 4.2 mg/g. The purification efficiency reached 87% at the initial concentration of Cu2+ ions being 97 mg/l. Tests to estimate the specific heat of combustion of C. kessleri biomass and used biosorbents based thereon were carried out by the calorimetric method using a bomb calorimeter. The specific heats of combustion were 22,125 kJ/kg and 21,674 kJ/kg, respectively. A comparison of these values with traditional energy carriers is given. A technological scheme has been developed for a waste-free cycle of using C. kessleri to treat wastewater from industrial enterprises with the production of several valuable resources as end products, such as purified water, energy resources, fertilizers, and recycled metals. The obtained results of our study can be applied in technologies for post-treatment of wastewater from various industrial enterprises using biological non-waste resources.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микроводоросль Chlorella</kwd><kwd>тяжелые металлы</kwd><kwd>сточные воды</kwd><kwd>биосорбция</kwd><kwd>безотходное использование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microalgae Chlorella</kwd><kwd>heavy metals</kwd><kwd>wastewater</kwd><kwd>biosorption</kwd><kwd>waste-free use</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования Российской Федерации в рамках проекта «Технологические вызовы и социальноэкономические преобразования в контексте зеленых переходов» (Соглашение № 75-15-2022-1136 от 01.07.2022).</funding-statement><funding-statement xml:lang="en">The research was supported by the Ministry of Science and Higher Education of the Russian Federation under the project “Technological Challenges and Socioeconomic Transformation in the Context of Green Transitions” (Agreement No. 75-15-2022-1136 dated 01.07.2022).</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">ГОСТ 4388-72.
