Jun 3, 2017 · Intensified and large-scale pig production leads to large amounts of manure production, and appropriate manure management is urgently needed to reduce manure emissions and environmental pollution. The MFB system has been introduced to recycle these wastes as a resource.
Apr 15, 2020 · Pig manure, cattle manure, and chicken manure are from the farms near the North Campus of Northwest University of agriculture and forestry technology, and no antibiotics have been used in the farms in the near future (Girotto et al., 2017). The biogas slurry is taken from the biogas digester which is normally used by the farmers in Cuixigou, Yangling, Shaanxi Province as the inoculum.
Apr 15, 2020 · Pig manure, cattle manure, and chicken manure are from the farms near the North Campus of Northwest University of agriculture and forestry technology, and no antibiotics have been used in the farms in the near future (Girotto et al., 2017).
Mar 14, 2024 · Whether advanced biological waste treatment technologies, such as hydrothermal pretreatment (HTP) integrated anaerobic digestion (AD), could enhance the removal of different antibiotics remains unclear. This study investigated the outcome of antibiotics and methane productivity during pig manure treatment via HTP, AD, and HTP + AD. Results showed improved removal efficiency of sulfadiazine
animal manure can increase biogas yield up to 400% compared to mono-digestion of the same substrate. Co-digestion of pig manure with glycerol at the ratio of pig manure: glycerol equal to 24:1 under mesophilic condition increased biogas yield up to 400% relative to mono-digestion of pig manure alone. [9, 10] Many researches
Dec 7, 2022 · Some scholars have also found MCG archaea in biogas fermentation systems; Yuan et al detected MCG archaea in a mixed biogas fermentation system of corn straw and pig manure, and Chen found them in an anaerobic bioreactor treating animal manure; Wilkins et al found MCG archaea in a biological treatment reactor for beverage plant wastewater with abundance second only to methanogens.
Jan 16, 2024 · This paper presents a review of additives used in different stages of anaerobic digestion of agricultural waste in terms of gas production performance, including associated bacteria and enzymes for accelerating the rate of hydrolysis, zeolites for controlling ammonia-nitrogen concentration/conductive materials for improving acid accumulation, an
Jan 2, 2014 · AE 1.5 mL CH4 ⋅g COD -1 ⋅d -1 ) than the single MV anaerobic treatment [17]. Thus, the co-digestion of mixed raw materials was found to balance the C/N ratio, dilute toxic substances, and
Jul 1, 2013 · The ectopic fermentation system (EFS) is an advanced technology for treating farm wastewater, and it reduces ammonia nitrogen emission and nitrogen loss of fermentation products. This study observed the functional bacteria succession related to nitrogen metabolism in EFS by high throughput sequencing, and evaluated their associations with environmental factors.
Processes. 2021, 9, 1324 2 of 15 . VS. add (volatile solids added) [5]. If all the swine manure in Taiwan is converted to biogas by anaerobic digestion, predictable annual biogas production is
Mar 5, 2022 · They can be found in a diverse environment, such as POME sludge (Jamali et al. 2019; Mahmod et al. 2019; Zainal et al. 2018), sludge from municipal wastewater plants (Chang et al. 2011; Viana et al. 2019), sludge from food waste (Li et al. 2018), cattle dung (Sen and Suttar 2012), pig manure (Wang et al. 2011) and marine sediments (Liu et al. 2018), many of which has been extensively studied.
High temperature fermentation technology promotes the rapid fermentation of pig manure, and at the same time, high temperature can kill the bacteria and insect eggs in it. And in the process of composting pig manure, composting equipment will help you mix, crush and turn, etc., to make work more efficient.
Jun 1, 2019 · A comparative study of pig manure with different waste straws in an ectopic fermentation system with thermophilic bacteria during the aerobic process: Performance and microbial community dynamics
boundary of the life cycle was the collection and transfer of pig manure to the treatment area. Since the processing area was in the large-scale pig farm where pig manure was collected, the manure transportation process was not included. And the ending boundary was solid waste forming mature compost products.
Jan 14, 2021 · (1) Objective: The objective of this study was to screen amoxicillin (AMX)-degrading bacterial strains in pig manure and optimize the fermentation conditions for these strains to achieve high fermentation rate, which can provide an effective way for the practical application of bacterial strains as antibiotic-degrading bacterial in treating livestock waste for antibiotic residues.
