2015/12/1/ · 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.
2024/6/21/ · Considering the economy and long-term operation of the equipment, the heat exchanger pipe in the fermenter is made of 304 stainless steel. The pipe is
2022/3/16/ · The data received on the pig manure amount and its nutrient (nitrogen and phosphorus) content is used to calculate the quantity and quality of resulting organic
2014/4/3/ · A new method for characterizing the aerobic layer thickness in pig manure, based on Fourier transform infrared microspectroscopy (FTIRM), is presented to improve the anaerobic/aerobic co-process
2014/3/1/ · This study aimed to investigate the characteristics of anaerobic digestion of pig manure depending on various growth stages and initial substrate concentrations in a
2024/5/20/ · The large-scale production of maricultural solid waste is not used effectively and has a significant impact on the environment. However, there is no report on the utilization of solid waste in mariculture of maricultural and agricultural solid waste. At present, aerobic composting is a simple and feasible means of waste resource utilization,
2021/1/1/ · Microbial community and function in nitrogen transformation of ectopic fermentation bed system for pig manure composting. Author links open overlay comprising Bacillus licheniformis, Bacillus subtilis, and Penicillium chrysogenum, at different stages of swine manure (SM) aerobic composting, specifically the initial stage and
2022/9/10/ · This study compares the physicochemical properties, lignocellulose degradation, microbial community composition, and carbohydrate-active enzymes (CAZymes) in ectopic fermentation systems (EFS) of pig manure mixed with either conventional padding (C) or straw waste (A). The degradation rates of cellu
The manure from cattle farms is collected in a fermenter with the addition of bacterium for anaerobic fermentation (biogas fermentation; Ozbayram et al., 2018), and after the completion of fermentation, the solid digestate is separated out through solid–liquid separation and can be used as bedding after simple treatment (Zhang et al., 2020).
2023/6/13/ · 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
2019/6/1/ · Ectopic fermentation systems (EFSs), which involve the ex-situ decomposition of pig manure, represent an improved treatment method for deep-litter systems. Transformation and decomposition in a deep-litter system has been studied, in which the animals were raised on a thick layer of litter (Westerath et al., 2009).
