Sludge Composting. According to statistics there are nearly 600 sewage treatment plants in China at present. And the sludge generated during the sewage treatment process is about 0.3-0.5% of the sewage treatment capacity. If we calculate based on this data, China’s municipal sewage treatment plants discharge is about 1.4 x 10t/a of dry sludge.
Assessment of the maturity and stability of the compost resulting from mixing tomato residues with chicken manure, using a rotary drum bioreactor which is characterized by reducing the time of the active phase to several hours or days instead of weeks or months.
Sewage sludge is the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater. The term "septage" also refers to sludge from simple wastewater treatment but is connected to simple on-site sanitation systems, such as septic tanks . When fresh sewage or wastewater enters a
Apr 21, 2023 · Economical efficiency: With simple operation, this machine has a high degree of automation, small power consumption, and a competitive price. This machine is the perfect organic waste treatment equipment for slag liquid separation, including livestock breeding farm fecal sewage( pig manure, cow dung, chicken manure, duck feces), biogas slurry
Aug 1, 2023 · Ma et al. (2019) found that inoculation with mature compost increases the diversity of microbial communities in the medium- and high-temperature stages of sludge composting. Yang and Zhang (2022) improved the pile porosity and maturity by adding mature compost to kitchen waste.
Jan 1, 2024 · Additives are important for accelerating humification during aerobic composting. The impacts of porous additives biochar and volcanic rock on the physicochemical parameters, maturity indicators, microbial communities, and bacterial functional metabolism during the aerobic composting of cow manure were investigated in this study.
Aug 1, 2020 · Introduction. Poultry production is an important agro-industry worldwide. To take an instance from the global demand for chicken meat and chicken eggs, it was predicted to grow by 61% and 39% up to 2030, and approximate 457 million tons of chicken manure (CM) were globally produced each year (Hwang et al., 2020, Mao et al., 2020).
Aug 4, 2023 · The necessity of investigating the effects of compost derived from chicken manure on the chemical composition and storage of soil organic matter, pore space, and the ecotrophic structure of the
Global expectation for sustainability has prompted the transition of practices in wastewater treatment plants toward not only waste management but also energy and nutrient recovery. It has been shown that low-temperature hydrotherm (HT) treatment can enhance downstream biogas production via anaerobic digestion (AD). Yet, because the application of combined HT and AD is still at an early stage
Jun 13, 2023 · Poultry waste can be produced into high-quality organic fertilizers by composting. In this project, a microbial agent was constructed. The objective of this study was to analyze the effectiveness of additives (microbial agent (TB) and manure compost (TM)) on composting process of chicken litter with mushroom residue. Results indicated that TB exhibited the highest composting temperature (72.1
To optimize the composting process, Cao et al. (2017) inoculated fresh chicken manure with microorganisms after high temperature pretreatment, and determined the effect of high temperature pretreatment on chicken manure composting by analyzing the physical and chemical properties and nutrients. However, the effect of inoculating microorganisms
Aug 15, 2023 · The hydrothermal carbonation (HTC) of sewage sludge (SS) produces a large amount of an aqueous phase (AP), which has become a bottleneck for the development of HTC. Herein, the effectiveness of the AP from HTC as a moisture regulator for composting was investigated in terms of nitrogen (N) retention and humification.
The aim of this study was to investigate the influence of inoculants on compost stability, maturity and enzyme activities during composting of chicken manure and cornstalk. Two microbial inoculants (originated from aerobic municipal sludge and municipal solid waste, respectively) were used in composting at the rate of 0.3% of initial raw
Jun 1, 2021 · Method Three materials, namely sawdust, sewage sludge, and chicken manure were mixed at different ratios (dry weight basis) to reach the initial bulk density of 0.40 Kg.L-1 , the temperature of 30
