Производство и накопление различных органических отходов ежегодно растёт, представляя угрозу человечеству и окружающей среде: отходы, попадая на свалку, производят климатически активные газы и фильтруются в почву и водные бассейны. Анаэробное сбраживание является хорошо известным способом биологической конверсии органических отходов животноводческих комплексов. Двухстадийное анаэробное сбраживание (ДАС) с получением водороди метансодержащего биогаза, соответственно в первом (кислотогенном) и втором (метаногенном) реакторе представляет собой перспективную технологию для более полной материальной и энергетической конверсии органического вещества отходов. Хотя ДАС не является новым процессом, информация о стабильности процесса и эффективных условиях эксплуатации ограничена и часто противоречива. В данной работе изучено влияние угольной ткани в качестве материала-носителя биомассы на эффективность термофильного метаногенеза жидкой фракции эффлюента темновой ферментации при переработке модели органических отходов АПК в период запуска системы. Нагрузка по органическому веществу в реакторе темновой ферментации (ТФ) была постоянной (24 г ОВ/(л сут)), в то время как в метаногенных анаэробных биофильтрах изменялась путем соответствующего изменения гидравлического времени удержания (ГВУ) от 1,6 до 3,2 суток. Среднее содержание ХПК в инфлюенте анаэробных биофильтров составило 7400 мг ХПК/л. В среднем, объемный выход водорода был 1,35 л/(л сут), а удельный выход водорода 56,2 мл/ г ОВ были достигнуты при содержании водорода в биогазе 47,9% и рН в реакторе ТФ 4,22. Угольная ткань способствовала увеличению выхода метана в период запуска и позволила увеличить объемный выход метана в среднем на 25% на стационарных режимах при ГВУ 3,2 и 2 суток. При ГВУ 1,6 суток объемный выход метана был больше на 70% в реакторе с угольной тканью, однако оба реактора работали нестабильно. Следует отметить, что анаэробные биофильтры в качестве инфлюента использовали жидкую фракцию эффлюента темновой ферментации, которая является сложным субстратом ввиду низкого рН.

The production and accumulation of various organic wastes increases annually, posing a threat to humanity and the environment: wastes ending up in landfills produce climate-active gases and are filtered into soil and water basins. Anaerobic digestion is a well-known method of biological conversion of organic wastes from livestock complexes. Twostage anaerobic digestion (TAD) with the production of hydrogenand methane-containing biogas, respectively, in the first (dark fermentation) and second (methanogenic) reactors is a promising technology for more complete material and energy conversion of organic matter in wastes. Although TAD is not a new process, information on the process stability and effective operating conditions is limited and often contradictory. In this paper, the effect of carbon cloth as a biomass carrier material on the efficiency of thermophilic methanogenesis of the liquid fraction of dark fermentation effluent during the processing of a model of organic wastes from the agro-industrial complex during the system startup period was studied. The organic matter load in the dark fermentation (DF) reactor was constant (24 g VS/(l day)), while in the methanogenic anaerobic biofilters it was varied by changing the hydraulic retention time (HRT) accordingly from 1,6 to 3,2 days. The average COD content in the influent of anaerobic biofilters was 7400 mg COD/l. On average, the hydrogen production rate of 1,35 l/(l day) and the hydrogen yield of 56,2 ml/g VS were achieved at a hydrogen content in biogas of 47,9% and a pH in the DF reactor of 4,22. The carbon cloth contributed to an increase in the methane yield during the start-up period and made it possible to increase the volumetric methane yield by an average of 25% at steady-state modes at HRT of 3,2 and 2 days. At HRT of 1,6 days, the methane production rate was 70% higher in the reactor with the carbon cloth, however, both reactors operated unstably. It should be noted that anaerobic biofilters used the liquid fraction of dark fermentation effluent as an influent, which is a complex substrate due to its low pH.
