The pig manure is in this loose material state, the fermentation temperature is controlled at 60-70℃, and the fermentation can be completed by maintaining it for 3-4 days. Adopt the advanced fermentation technology.
Apr 15, 2020 · At medium temperature, the biogas output per unit of pig manure/corn straw is better than that of cow manure/corn straw. When the ratio of pig manure to corn straw is 9:1, the maximum gas production is 283.74 mL/g TS; when the ratio of cow manure to corn straw is 7:3, the minimum gas production is 121.59 mL/g TS.
Jul 25, 2023 · The two strategies for processing pig manure are proposed in this study—storage and composting. The present study examines the changes in the physicochemical properties of treated manure, in
Jan 1, 2021 · The annual quantities of raw waste are as follows: cow manure - 1252 t / a; chicken manure - 427 t / a and pig manure - 639 t / a. The manure is collected in a preliminary tank and then pumped to
Jun 1, 2022 · The substrates for biogas production were composed of maize silage A, with a yield of 4287 t·year −1 (ensiled between January and May 2015); maize silage B, with a yield of 6405 t·year −1 (June 2015 – April 2016); pig manure, with a yield of 13,190 t·year −1; cattle manure, with a yield of 428 t·year −1; and a 1:1 mixture (v:v) of pig manure and digestate.
Mar 1, 2014 · Using pig manure to promote fermentation of sugarcane molasses alcohol wastewater and its effects on microbial community structure Author links open overlay panel Peihong Shen a b , Han Fei a , Su Shuquan c , Zhang Junya a , Chen Zhineng d , Li Junfang a , Gan Jiayi d , Feng Bin d , Wu Bo e
Mar 16, 2022 · The method involves the use of mathematical models, which describe the most common and emerging technological solutions for pig manure processing: long-term storing (maturing), passive and active composting, fermentation in drum and chamber fermenters and multi-stage processing with biological treatment [45,46,47,48,49,50].
Feb 4, 2020 · The aim of this study was the evaluation of the influence of temperature, initial organic load, and C/N ratio in the biochemical hydrogen potential (BHP) by dark fermentation (DF) of mixtures composed of residual biomass derived from the Colombian agro-industry (pig manure, cocoa mucilage, and coffee mucilage) to contribute to residue management and the development of a bio-based economy in
Jan 1, 2023 · The actual values of methane production from pig manure and rice straw fermentation alone in the experiment were determined to be 248.4 and 181.71 mL/g VS, respectively; then, the theoretical calculated values were weighted and superimposed according to the amount of methane production from different proportions of mixed substrates.
Dec 1, 2023 · For example, alkaline in situ fermentation may suit chicken manure better due to the high nitrogen content and high TS content of chicken manure; however, 5 % NaOH pretreatment aiming at more methane production is more suitable for cow manure.
˜e main research content is to take pig manure as the object, conduct anaerobic fermentation through pH adjustment to obtain P-rich supernatant, and then use the two-chamber electrolytic tank to
Feb 1, 2020 · The effect of pig manure content on fermentation. Based on the analysis of the gas production per unit of TS, when the pig manure content is 80%, the unit TS produced has the highest gas yield of 344 ml/g, which is 58.9% higher than that of pure wheat straw fermentation. Fermentation increased by 11.43%.
May 30, 2006 · The results obtained so far from the ongoing IREE-funded study at the SROC, in which a continuous batch fermenter is fed with liquid swine manure with about 1-2% total solids content, have shown that levels of as high as 28% in hydrogen concentration in the off gas from the fermenter can be achieved.
Pig manure is an important biomass resource, and anaerobic fermentation is one of the main ways to treat pig manure. However, the residual anaerobic fermentation slurry becomes a new pollutant; therefore, it is essential to study whether the anaerobic fermentation slurry could be used for soil anaerobic disinfection and enhance the efficiency of the process.
during the process of two different manure treatment -anaerobic fermentation and aerobic composting, and the advantages and disadvantages of the two treatment were compared on the basis of environmental impact. The starting boundary of the life cycle was the collection and transfer of pig manure to the treatment area.
