Apr 30, 2024 · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk. In this study, the effects of process
Apr 23, 2024 · The composting of pig manure along with straw to generate organic compost has exhibited superiority over mixing manure with wash water for anaerobic digestion for global warming, albeit inferiority in terms of acidification and eutrophication.
Jan 22, 2024 · The duration required to compost pig manure can vary depending on several factors. With the right conditions and techniques, pig manure can be transformed into nutrient-rich compost within a few months. However, it is important to note that the composting process can take longer under certain circumstances.
Using pig manure and corn straw as raw materials for high-temperature composting, setting three different treat- ments: C/N 15, C/N 25, and C/N 35. Composting period is 120 days, which contains 30 days for ventilation cycle by forced continuous ventilation. Sampled on 0, 22, 30, 60, 90, 120th days,
This equipment consists of transmission device, running gear, turning device and other main components. During turning, SEEC wheel type compost turner can blend the raw material and treated pig manure will be moved 0.7 meter to 1 meter away. By this method, you can realize high-efficiency turning and uniform blend.
Monitoring the internal temperature with a probe-type thermometer can indicate when to turn the windrow (Figure 6). To efficiently compost manure, turn the windrow when the internal temperature drops below 120 degrees F. After five to six turns, the manure should be composted. Temperatures should be taken at various locations and depths.
Jan 1, 2024 · This result showed that the addition of volcanic rock was more conducive to improving the richness and diversity of microorganisms during cow manure composting, which may be because volcanic rock can improve the aerobic condition of the composting.

Feb 23, 2024 · The Qinghai-Tibet Plateau (QTP) is characterized by an extreme hypoxia, which may lead to lack of sufficient oxygen for compost production, and thus seriously affecting the compost quality. The moisture content (MC) has a direct effect on the oxygen content of composting pile. At present, the research on the optimum moisture content of compost production on the QTP is still lacking. This study
Dec 1, 2022 · In this study, we used both chicken and pig manure as the main composting substrates and applied biochar to construct multiple industrial-scale composting systems for processing. By the means of high-throughput sequencing and quantitative PCR technologies, we characterized the dynamic changes of the bacterial community, ARGs and MGEs, during
Feb 1, 2024 · Phenol-rich wine grape pomace (WGP) improves the conversion of pig manure (PM) into humic acid (HA) during composting. However, the impact of using combinations of Fe 2 O 3 and biochar known to promote compost maturation remains uncertain.
Feb 1, 2024 · Greenhouse gas (GHG) emissions from manure management processes deserve more attention. Using three industrial-scale experiments, this study comprehensively evaluated the effects of different aeration coupled with semi-permeable membrane-covered strategies on the structure and function of bacterial communities and their impact on GHG emissions during dairy manure aerobic composting.
The two self-propelled compost turners can be driven by one person, it has a great flexibility. The moving type compost turner uses diesel oil for powder and use the motor works with water. There is water tank on the machine, you need to add water. It has fan as its refrigeration system. The maximum speed is 2200r/min, working speed is 6-10m/min.
