2012/9/1/ · 1. Introduction. Energy crisis and global warming are considered to be two most serious problems worldwide [1].Biomass energy, as a renewable and sustainable form of energy, is becoming more important due to its environmentally-sound and energy-saving production [2].Development of a livestock industry is believed to be a key
2021/9/1/ · The fermentation products of M0, M3, M5, T0, T3 and T5 were divided into two parts consisting of biogas slurry (S) and residue (R). Eleven targeted ARGs including Tetracyclic antibiotics: tetQ, tetX, tetM, tetW, tetO, Macrolide antibiotics: ermB, ermF, mefA, Sulfanilamide antibiotics: sul1, sul2 and the class 1 integron-integrase gene (intI1) in
2021/2/13/ · 1 INTRODUCTION. Biochar, the product of pyrolysis of organic biomass, is characterized by abundant recalcitrant organic carbon (OC) and highly porous structure (Huang et al., 2018; Liu, Zheng, et al., 2020; Liu, Wang, et al., 2020).It has been demonstrated as a more cost-effective relative to activated carbon and eco-friendly soil
This study used biogas residue produced by anaerobic fermentation of food waste as the raw material in large-scale windrow composting. The effects of the addition of a microbial consortium on the physical and chemical properties and stability of composting of biogas residue were studied. The maturit
2017/5/1/ · Afterwards, these materials were blended in proportions of 1:1, 1.8:1, 2.8:1, and 3.8:1 based on their dry mass. The biogas slurry (water content of 84.1%) from final-stage fermentation, taken from a normal biogas digester used in the poultry feeding industry in the Central China Economic District, was used as the inoculation.
2022/7/15/ · The study demonstrated that dry anaerobic fermentation biogas residue of KW can be pyrolyzed into biochar and almost half amount of the biogas residue was reduced. By adding the biochar into dry anaerobic fermentation system of KW, methane production was significantly promoted. This developed a new recycle route for improving
2022/3/1/ · The average long-term biogas yield of the biogas station under investigation is 130.5 m 3 t −1 which (related to dry weight of feedstock and after conversion to CH4 at 0 °C and 101.3 Pa) is 5% lower than reported by Samarappuli and Berti (2018) and some 6% lower than reviewed by Böjti et al. (2017). The reason may be that the
2018/12/15/ · The results showed that the addition of biogas slurry during the fermentation of raw materials improved biogas total production and CH 4 total production and also produced CH 4 in advance. The total amounts of biogas and CH 4 produced were the largest when the amount of biogas slurry added to the fermented mixture was 30%.
2013/4/15/ · Biogas residue is renewable, low-cost, and is composed of organic material that contains the necessary nutritional elements to sustain the growth of microbes. In this study, Biogas residues were used as a substrate for bio-pesticides production by solid state fermentation. Principal component analysis of biogas residue indicated that
A modified biogas solid-state fermentation pilot system, namely the flexible roof membrane garage-type biogas solid-state fermentation system (GBFS), was used in this study. The overall design of the fermentation device is shown in Fig. 1a. The reactor contained two fermentation units, each with a total volume of 75 m 3 (Fig. 1b). The system
2022/8/17/ · Purpose As a high-yield by-products of biogas engineering, biogas residue (BR) are limited in the application of soil fertility due to their ecological threat. Therefore, conversing BR into biochar is to be considered. However, whether BR biochar still had ecological risk to soils (especially the widely distributed soils such as Ultisol soil)
Dry Fermentation Unit Product description: Dry Fermentation technology differs from traditional "wet digester" tank systems that utilize liquid feedstock and physically stir and agitate materials with moving parts. During the fermentation process, no further mixing, pumping or stirring is necessary inside the digester, nor is further material added.
2022/1/6/ · unit area of farmland [16]. China put forward the “Opinions on Accelerating the Utilization of Waste from which is composed of an above-ground fermentation tank, a biogas residue storage, a biogas slurry sedimentation tank, and a discharged water storage tank (Figure2). Based on the principle of random sampling, 18 samples for each …
In this way, we can make use of edible mushroom residue as a substrate for resource utilization and provide basic data and theoretical basis for the design and scale-up with anaerobic fermentation to biogas reactor. Keywords Biogas · Computational uid dynamics (CFD) · Continuous stirred tank reactor (CSTR) · Agaricus bisporus
2022/10/4/ · Agaricus bisporus production gets a lot of residues, which could be fermented by a continuous stirred tank reactor (CSTR). This research was conducted to study the characteristics of the multiphase flow field in the reactor and its influence on the efficiency of biogas production in the CSTR fermentation process of Agaricus bisporus …
