Oct 1, 2022 · Compost quality greatly depends on maturity and humification, and odor emissions can cause severe air pollution and nutrient losses during composting.In this study, a laboratory trial was carried out under different aeration conditions to explore the effects of boundary-oxygen content (microaerobic, aerobic, oxygen-rich) on maturity, humification, and odor emissions during chicken manure
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.
Jan 29, 2024 · Due to the rapid development of animal husbandry, the associated environmental problems cannot be ignored, with the management of livestock and poultry manure emerging as the most prominent issue. Composting technology has been widely used in livestock and poultry manure management. A deeper understanding of the nitrogen conversion process during composting offers a theoretical foundation for
Jan 8, 2020 · The present study indicates the importance of co-composting material to control gases emissions and compost quality during chicken manure composting. The chicken manure had the greatest amount of labile organic matter such as WEC, WEN, HWEC and HWEN.
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
Dec 7, 2022 · As increasing soil organic matter is considered one of the main strategies for reducing desertification in Europe, the production and use of high-quality composts has gained importance during the last decade. It is undisputed that the quantity and quality of humic substances (HS) and their fractions, i.e. fulvic acids (FA) and humic acids (HA) in compost are considered important indicators of
Effect of aqueous phase from hydrothermal carbonization of sewage sludge on heavy metals and heavy metal resistance genes during chicken manure composting - ScienceDirect. Journal of Hazardous Materials. Volume 471, 5 June 2024, 134398.
Aug 4, 2023 · DOI: 10.1016/j.wasman.2023.07.028 Corpus ID: 260659098; Ammonia assimilation is key for the preservation of nitrogen during industrial-scale composting of chicken manure. @article{Zhu2023AmmoniaAI, title={Ammonia assimilation is key for the preservation of nitrogen during industrial-scale composting of chicken manure.}, author={Lin-Min Zhu and Caihong Huang and Wei Li and Wei min Wu and Zhurui
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.
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).
May 1, 2020 · Co-composting is a simple and inexpensive alternative for stabilizing and reducing jointly different biodegradable waste. In this study, the feasibility of co-composting chicken manure (CM
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
This work is based on a simple concept: Activated sludge A+B=C Physicochemical characterization of the activated sludge Activated sludge + poultry manure = Compost For an activated sludge rich in decomposed sawdust, a First, physicochemical analysis (pH, temperature and considerably high C/N ratio (191.17) attracts attention. conductivity
Apr 6, 2024 · Sustainable management of sewage sludge is a challenge to the world. With a high content of organic material and essential nutrients, sewage sludge has been viewed as a cost-effective option for improving soil quality [1,2]. Its high concentration of organic matter and nutrients makes it logical to utilize sewage sludge as a fertilizer . Due to
Aug 17, 2023 · We first revealed the behavior and biochemical mechanism of high iron attapulgite (HIAP) and different dosages affecting sewage sludge (SS) composting. HS/TOC ratio increased, but HA/TOC and HA/FA ratios reduced with the increase in HIAP dose. High-dose HIAP promoted the formation of more HS by weak catalytic effect but could bind more FA than HA by strong adsorption effect to inhibit the
