Feb 1, 2024 · Pig manure: 1200 °C, O 2 /CO 2 /N 2: Drop tube reactor: The optimum operating conditions for the gasification of the pig manure in terms of syngas heating value and yield 1200 °C, and a gasification atmosphere composed of a mixture of O 2 /CO 2 /N 2. Syngas: 22 mol/kg [87] Chicken Manure: 450 °C, 15 min: U-type batch reactor
May 7, 2020 · These were fed with pig manure and glucose as co‐substrates. Hydraulic retention times were 22, 11, 6, and 3 d. Target pH was 5.5 within 5.3–5.7 and controlled by varying organic loading rate.
Sep 10, 2022 · 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).
Jan 1, 2021 · The EFBS was innovatively designed a combination system with a steel structure house, spray pond, fermentation tank with bedding litters, walking upender and manure slurry spraying system.
Jul 25, 2023 · The samples were divided into three groups: PM raw–untreated pig manure, PM compost 10W–pig manure after 10 weeks of composting, PM storage 4 M–pig manure after four months of storage. Full
Jan 18, 2022 · This study investigated the fate of antibiotic resistance genes (ARGs), metal resistance genes (MRGs), and class 1 integron-integrase gene (intI1) during thermophilic fermentation of swine manure
Apr 1, 2024 · 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 Bioresour.
For the comparison between the two systems, pig manure input is 3.37E+14 sej/j of IMS, which is 60.10% lower than the fertilizer input of MS. Pesticides input of MS with 4.77E+13 sej/j accounts for 0.84% of total emergy input, and that of no input of IMS.
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. This research aims to build a smart solar chicken manure fermentation system to control the conditions of chicken manure fermentation effectively, improve quality, and solve the
Jan 16, 2024 · Recently, Chen Biao (Biao, Shaoying, et al., 2020) conducted a test on the effect of two non-conventional trace elements, such as Se and W, on the fermentation performance that was added to the pig manure fermentation system at different concentrations. The results showed that they could jointly promote the gas production efficiency of the anaerobic digestion system, and the optimal
Nov 9, 2017 · Background Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high
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 various agricultural by-products.
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.
Jun 1, 2019 · 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).
