2009/3/1/ · The semi-continuous operation of mixture of llama–cow–sheep manure proved to be a reliable system, which could be operated with good stability. The results suggest that in a system digesting a mixture of llama-cow-sheep manure at low temperature (18–25 °C) the maximum OLR value is between 4 and 6 kg VS m 3 d −1.
2024/4/1/ · Sludge and chicken manure anaerobic co-fermentation is an effective way to obtain volatile fatty acids (VFAs). Aimed at exploring the effects of co-fermentation on VFAs production and microbial characteristics, six experimental groups with different pH were set up. The concentration of VFAs under alkaline conditions was 1.4 times that of
In this study, we investigated rural household biogas digesters that were used as fermentation devices to conduct low-temperature (15.2-17.8°C) pilot experiments to specifically evaluate biogas production by mixed anaerobic fermentation of rapeseed cake and sheep manure using seven different ratios of high solid content waste.
Key words: biogas production through anaerobic fermentation /; agricultural waste /; rape seed cake /; resource utilization of livestock manure; Abstract: In order to make full use of the waste resources such as rape cake and cow dung and sheep manure and improve the biogas production performance at the same time, this test was based on the agricultural

Anaerobic digestion (AD) can convert agricultural and pastoral wastes such as crop straws and livestock manure into methane, and has emerged as one of the most promising and rapidly increasing technologies to address energy and environmental concerns [4], [5]. AD mainly includes mono-digestion and anaerobic co-digestion (co-AD).
2020/10/31/ · The physicoc hemical compositions of cow manure and sheep manure showed that v olatile solid (VS) contents were close to each other in manure compositions (77.6% and 64.7%, respectivel y), while
2022/11/21/ · Fermented organic fertilizers made from pig manure contaminated with antibiotics are widely used in fruit tree production. However, their effects on the residual antibiotics and the spread of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in apple orchards are still largely unknown. In the present study, we
2018/2/14/ · The fermentation of plant materials in the ruminant digestive tract and environmental conditions in the rumen, such as pH, temperature, and redox potential, resemble the anaerobic digestion process in a biogas reactor, at least concerning the first steps of the process (hydrolysis and acidogenesis) and hydrogenotrophic
2017/5/1/ · According to Gallegos et al. (2017), anaerobic digestion occurs in three types of fermentation relative to temperature; low at 15 • C, medium at 30 to 38 • C, and high 50 to 55 • C
In this study, the potential to enhance the performance in two full-scale biogas plants operating with cattle manure, in mono-digestion or combined with poultry manure, were investigated. Four continuously-fed laboratory-scale reactors were operated in sets of two, in which one reactor in each set was increased from 37 展开
2023/11/9/ · Co-digestion performance of hulless barley straw mixed with pig, fowl, sheep, and cow manure induced by microbial changes were studied based on mesophilic batch anaerobic digestion (AD) experiments. The mixed AD of hulless barley straw and four kinds of manure yielded the synergistic promotion effect of materials. The highest …
