Целью данной работы было определение оптимальных значений коэффициента рециркуляции (RR) сгущённого эффлюента при применении нового подхода к интенсификации анаэробной конверсии, обеспечивающего выход биогаза повышенного качества. Данный подход включает рециркуляцию сгущенного эффлюента и предварительную обработку смеси исходного субстрата и сгущённого эффлюента в аппарате вихревого слоя. Для этого была рассмотрена работа экспериментальной биогазовой установки без рециркуляции и с рециркуляцией, начиная с очень низких значений RR, от 0,034 до 1, для обеспечения высоких объёмного метана (ОВМ, MPR) и удельного (УВМ, MY) выходов метана. С точки зрения ОВМ и УВМ наиболее привлекательными выглядят коэффициенты рециркуляции 0,034 и 0,071, однако при коэффициенте рециркуляции 0,5 содержание сероводорода снижается до 14 ppm с одновременным увеличением ОВМ на 12% по сравнению с контролем.</p></abstract><trans-abstract xml:lang="en"><p>Agricultural waste, called biomass, is of great interest as a renewable energy source. The purpose of this work was to determine the optimal RR values of the solid digestate when applying a new approach to the intensification of anaerobic conversion, providing a high quality biogas yield. This approach includes solid digestate recirculation and pretreatment a mixture of raw waste and solid digestate in a vortex layer apparatus. For this, the operation of an experimental biogas plant without recirculation and with recirculation was considered, starting from very low RR values, from 0.034 to 1, to ensure a high methane production rate (MPR) and methane yield (MY). From the point of view of MPR and MY, the recirculation ratios of 0.034 and 0.071 look the most attractive, however, with a recirculation ratio of 0.5, the content of hydrogen sulfide de-creased to 14 ppm with a simultaneous increase in MPR by 12% compared to the control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анаэробная биоконверсия</kwd><kwd>биогаз</kwd><kwd>рециркуляция эффлюента</kwd><kwd>сгущённый эффлюент</kwd><kwd>аппарат вихревого слоя</kwd><kwd>предобработка</kwd><kwd>органические отходы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anaerobic digestion</kwd><kwd>biogas</kwd><kwd>digestate recirculation</kwd><kwd>solid digestate</kwd><kwd>vortex layer apparatus</kwd><kwd>pretreatment</kwd><kwd>organic waste</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">.
