Dec 1, 2023 · The role of protein shell (PS) amendment in altering the fungal community during pig manure (PM) composting was investigated. Six different dosages of PS based on the dry weight of PM (0 %, 2.5 %, 5 %, 7.5 %, 10 %, and 12 %; T1–T6, respectively) were mixed with wheat straw to make the initial feedstock and composted for 42 days.
Oct 15, 2022 · Pig manure is rich in protein and other nitrogen substances, with a low C/N (Söderftröm et al., 2002). The fermentation using pig manure as sole substrate can easily cause an ammonia suppression, which is unfavorable to biogas production and leads to poor composting efficiency (Shen et al., 2018).
Jun 3, 2017 · The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM).
May 3, 2024 · Biochar has been reported as an effective additive to enhance methane production during anaerobic digestion due to its large specific surface area, ability to enrich microorganisms, electrical conductivity, and low cost. However, it is not clear whether these effects are applicable to the anaerobic co-digestion (co-AD) of hulless barley straw and pig manure. Under medium temperature batch
Jan 1, 2023 · The objective of this study was to optimize the process parameters of the anaerobic co-digestion of pig manure and rice straw to maximize methane production and system stability. In this study, batch experiments were conducted with different mixing ratios of pig manure and rice straw (1:0, 1:1, 1:5, 1:10, and 0:1), total solid concentrations (6%, 8%, 10%, 12%, and 14%), and inoculum accounts
Aug 1, 2024 · China, leading the world in pig-rearing and pork consumption, saw its production of swine manure (SM) surpass 600 million tons in 2020 (Lin et al., 2024, Liu et al., 2023b). Additionally, as per statistics from the Bolong fermentation tank, China holds the position of the world's foremost apple producer with a notable annual yield of
Jan 18, 2022 · 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
Apr 29, 2023 · Firmicutes dominated pig and chicken manure composts, while Proteobacteria and Chloroflexes dominated sheep and cattle manure composts (Wan et al. 2021). 7.5.2 Bacteria in Biogas Digester The bacteria used in the pretreatment may be derived from microbial cultures from previous fermentations, sludge, lignocellulosic substrates, rumen fluid, and
Jul 25, 2023 · The two strategies for processing pig manure are proposed in this study—storage and composting. (59,84% related to enteric fermentation, ... it is hard to determine the methane production ...
Jul 1, 2023 · To stringently simulate the stable fermentation process of EFS, a pig manure slurry ectopic fermentation was lasted for 66 days in experiment 1. This study compared the change of EFS indicator by using different padding materials under the CMA intervention first.
Apr 1, 2022 · Ex situ fermentation systems (EFSs) represent an organic agricultural technology that utilizes continuous dynamic aerobic fermentation of microorganisms to process livestock and poultry manure in batches with low pollution (Yang et al., 2018, Yang et al., 2019, Zhou et al., 2021).
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
In the present study, ectopic fermentation systems were treated with both solid and liquid waste from livestock. Then, the various physicochemical properties and compositions of microbial communities in different waste straws treatments were compared.
If you want to compost pig manure quickly, our pig waste fermentation tank is suit for you to improve working efficiency in pig manure composting systems. This is an In tank composting equipment in pig manure making process.
Nov 12, 2021 · Traditional chicken manure fermentation is mostly natural composting or exposure, which is not only time consuming but also susceptible to weather, resulting in uncontrollable quality and environmental pollution.
