Mar 1, 2014 · The characteristics of anaerobic digestion of pig manure from different growth stages were investigated. According to growth stage, batch experiments were performed using gestating sow manure (GSM), swine nursery with post-weaned piglet manure (SNM), growing fattening manure (GFM) and mixed manure (MM) as substrates at four substrate concentrations (40, 50, 65 and 80 gVS/L) under mesophilic
This fermentation process combines the advantages of deodorization, pest killing, disease destroying, nutrient enhancement, and elimination of secondary fermentation. Heat will be produced in the process of pig manure fermentation, which can effectively kill the parasitic eggs and disease contained in pig manure and prevent harm to crops.
In present study, four lengths of chopped cornstalks were amended with pig manure respectively for 100 days aerobic fermentation, which aimed to evaluate the impact of different length of agricultural solid wastes on gaseous emission and dominating bacterial community succession and connection.
Feb 5, 2021 · 1. Introduction. Aerobic fermentation is regarded as an important component of sustainable development because it can reduce the environmental problems caused by organic waste, and fermentation products can replace chemical fertilizers to promote the development of circular agriculture (Cáceres et al., 2018; Janczak et al., 2017).
Jan 2, 2024 · Aerobic fermentation is effective in livestock manure compositing because of reduced time and space requirements 18. Researchers are attempting to enhance aerobic fermentation techniques to
Nov 27, 2023 · the pollution caused by them. Pig manure, cow manure, and wheat straw were mixed in di erent proportions (Table 1), and then EM bacterial agent was added separately, along with 0.3% of the organic material [17]. Aerobic fermentation was carried out in a home-made fermentation bucket with a volume of 2L, as shown in Figure 1, with holes punched
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
Furthermore, pig manure with sawdust, rape stem, and rice chaff and pig manure with sawdust, rice straw, and rice chaff vessels had higher concentrations of dissolved nitrogen, which were conducive to the conversion of fermentation wastes into useful fertilizer.
Aug 6, 2021 · Indeed, many recent studies have suggested composting with agricultural residues and manure as a potential solution for agricultural waste disposal all over the world [19, 20]. Composting is an aerobic, thermophilic, solid-state fermentation process where microorganisms play a major role. Microorganisms are the power system of composting.
Dec 1, 2015 · A total of 40 kg of a mixture of PFFR, pig manure and chaff at a ration of 1:2 was used. Rice chaff was added to adjust the initial C:N ratio to approximately 30:1 and the moisture content to approximately 60%. The PFFR-pig mature aerobic co-composting is referred to as “AC” in this paper.
Farming manure, garden waste, municipal sludge, kitchen waste and other wastes are composted by aerobic fermentation equipment, realizing the ripening, harmless, homogenization and drying of materials. It not only produces high-quality organic fertilizer, but also realizes clean production and improves the environment.
Jun 13, 2023 · This study established an anaerobic fermentation system using pig manure/corn straw as substrate to compare the influence on biogas production and Cu and Zn passivation by humic acid (HA), biochar (BC), fly ash (FA), and zeolite (ZS). Results showed that the cumulative gas production was promoted, and the availability of Cu and Zn was decreased substantially with the introduction of
Improper treatment of penicillin fermentation fungi residue (PFFR), one of the by-products of penicillin production process, may result in environmental pollution due to the high concentration of penicillin. Aerobic co-composting of PFFR with pig manure was determined to degrade penicillin in PFFR.
Dec 6, 2014 · Compared with the control in which pig manure was not fermented microbes and cellulase, the content of organic matter decreased by 2.95%~7.70% (except K and XE), the value of C/N decreased by 4.04
